[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] This application discloses a dust cover assembly, which is applied in a heated non-combustible device. It is used to avoid the opening 14 on the top cover 1 when the heated non-combustible device is in use, so that the aerosol product (not shown in the figure) can be inserted into the receiving cavity 61 through the opening 14. It is also used to cover the opening 14 on the top cover 1 when the heated non-combustible device is in standby mode, so as to prevent external dust or debris from entering the receiving cavity 61 and affecting the subsequent use of the heated non-combustible device.

[0027] Please refer to the dust cover assembly of this application embodiment. Figure 1 and Figure 2 The device includes a top cover 1, a guide 2, and a sliding cover 3. The top cover 1 has an opening 14 through which an aerosol product can be inserted into the receiving cavity 61 of the heated non-combustible device. In some embodiments, the top cover 1 is located on top of the heated non-combustible device, and a portion of the top cover 1 is exposed outside the heated non-combustible device, forming part of the housing of the heated non-combustible device.

[0028] The guide member 2 is installed on the top cover 1. The guide member 2 has two slide rails 21 arranged at intervals in the first direction. The slide rails 21 extend in the second direction. The first direction is perpendicular to the second direction. Both the first direction and the second direction are perpendicular to the height direction of the heating non-combustion device in use, that is, the extension direction of the accommodating cavity 61.

[0029] The sliding cover 3 is located between two slide rails 21. The sliding cover 3 has a blocking position for blocking the opening 14 and a clearance position for avoiding the opening 14. The sliding cover 3 can move between the blocking position and the clearance position relative to the slide rail 21 in a second direction via the guide structure 4. In this way, when the heated non-combustible device is in use, the sliding cover 3 can be moved to the clearance position to facilitate the insertion of aerosol products into the receiving cavity 61 from the opening 14. When the heated non-combustible device is in standby mode, the sliding cover 3 can be moved to the blocking position to prevent dust or debris from entering the receiving cavity 61 from the opening 14 and affecting the subsequent use of the heated non-combustible device.

[0030] Furthermore, the dust cover assembly in this embodiment has a small number of parts and a simple structure. During assembly, it is only necessary to make the sliding cover 3 cooperate with the slide rail 21 through the guide structure 4 and install the guide member 2 on the top cover 1. This facilitates the assembly of the dust cover assembly, helps to simplify the assembly process, and improves production efficiency.

[0031] In some embodiments, please refer to Figure 2 The guide member 2 is installed on the top cover 1 through the snap-fit ​​structure 5. The snap-fit ​​structure 5 includes a matching slot 52 and a hook 51. The hook 51 is located on the guide member 2 and extends toward the top cover 1. The slot 52 is located on the top cover 1. The hook 51 can be inserted into the slot 52 in the height direction of the heating non-combustible device and engage with the edge of the slot 52 to realize the connection between the guide member 2 and the top cover 1. The hook 51 can also abut against the side wall of the slot 52 in the first and second directions to restrict the movement of the guide member 2 relative to the top cover 1.

[0032] In some embodiments, the guide member 2 has two hooks 51, each hook 51 being connected to one of the two slide rails 21. That is, the two slide rails 21 are respectively mounted on the top cover 1 via a snap-fit ​​structure 5, which helps ensure the relative position of the two slide rails 21 and the accuracy of their installation position on the top cover 1. In other embodiments, multiple hooks 51 can be provided, with each slide rail 21 connected to multiple hooks 51. The slide rails 21 are snapped into the slots 52 on the top cover 1 via the hooks 51.

[0033] In some embodiments, the guide member 2 can also be mounted on the top cover 1 by fasteners, such as each slide rail 21 in the guide member 2 can be locked onto the top cover 1 by screws.

[0034] In some embodiments, please refer to Figure 2The top cover 1 is provided with a recessed groove 11. The groove opening of the recessed groove 11 faces the first direction and the second direction. The guide 2 and the sliding cover 3 are both located in the recessed groove 11. This can reduce the height of the guide 2 and the sliding cover 3 protruding from the top cover 1 when the groove opening of the recessed groove 11 is facing upward, which helps to reduce the height of the heating non-combustible device and realize the miniaturization design of the heating non-combustible device.

[0035] In some embodiments, please continue to refer to Figure 2 The top cover 1 is also provided with an installation groove 12 on the bottom wall of the sink 11. The shape of the installation groove 12 is adapted to the outer contour shape of the guide 2. The guide 2 is located in the installation groove 12. The guide 2 can be pre-positioned through the installation groove 12, which facilitates the fixed connection between the guide 2 and the top cover 1.

[0036] In the hook 51 structure, the latch 52 is located on the bottom wall of the mounting groove 12. After the guide 2 and the top cover 1 are fixedly connected by the snap-fit ​​structure 5, the position of the guide 2 can be restricted by the side wall of the mounting groove 12 to prevent the guide 2 from shaking.

[0037] In some embodiments, to prevent the position of the guide member 2 from changing during the guiding movement of the sliding cover 3 relative to the guide member 2, the guide member 2 is also fixed in the mounting groove 12 by adhesive. Before the guide member 2 is fixed to the top cover 1 by the snap-fit ​​structure 5 or by fasteners, adhesive is applied in the mounting groove 12. During the connection between the guide member 2 and the top cover 1, the guide member 2 is also glued to the groove wall of the mounting groove 12. This helps to ensure the connection strength and connection stability between the guide member 2 and the top cover 1.

[0038] In some embodiments, please continue to refer to Figure 2 The shape of the mounting groove 12 is adapted to the shape of the guide 2. In order to prevent the glue from being squeezed out during the installation of the guide 2 in the mounting groove 12, multiple protrusions 13 are provided on the bottom wall of the mounting groove 12. Two adjacent protrusions 13 are arranged at intervals. After the guide 2 is connected to the top cover 1 through the snap-fit ​​structure 5 or fasteners, the guide 2 and the protrusions 13 abut against each other. The guide 2 and the bottom wall of the mounting groove 12 enclose each other between two adjacent protrusions 13 to form a first glue-containing space. The setting of the first glue-containing space can reduce the probability of glue being squeezed out, help increase the contact area between the guide 2 and the top cover 1 and the glue, and improve the connection strength and connection stability of the guide 2 and the top cover 1.

[0039] In some embodiments, the recessed groove 11 or the mounting groove 12 on the top cover 1 can be omitted, as long as it is ensured that the position of the guide member 2 does not change during the movement of the sliding cover 3 relative to the guide member 2 after the guide member 2 is connected to the top cover 1. In some embodiments, the guide member 2 is installed in the mounting groove 12, and the guide member 2 can be fixedly connected to the top cover 1 by adhesive.

[0040] In some embodiments, to facilitate the installation of the guide member 2 on the top cover 1 and to improve the guiding performance of the two slide rails 21 for the guide member 2, please refer to... Figure 1 and Figure 2 The guide member 2 also has a first connecting part 22 and a second connecting part 23. The slide rail 21 has a first end 211 and a second end 212 located at both ends in the second direction. The first connecting part 22 connects the first end 211 of the two slide rails 21, and the second connecting part 23 connects the second end 212 of the two slide rails 21. In this way, the guide member 2 can be installed on the top cover 1 at one time without the need to install the two slide rails 21 separately, which facilitates the fixed connection between the guide member 2 and the top cover 1.

[0041] Furthermore, the slide rail 21 reciprocates relative to the guide member 2 in the second direction. When the slide rail 21 moves to the blocking position, one end of the slide cover 3 in the second direction contacts the first connecting part 22. When the slide cover 3 moves to the clearance position, the other end of the slide cover 3 in the second direction contacts the second connecting part 23. In this way, the two end side walls of the slide cover 3 can be prevented from contacting the top cover 1 during the movement of the slide cover 3, which helps to ensure the appearance of the top cover 1 and prevent the side wall of the top cover 1 corresponding to the end side wall of the slide cover 3 from being scratched by the slide cover 3.

[0042] Of course, in other embodiments, the guide member 2 has only two slide rails 21, which are respectively installed on the top cover 1. When the slide cover 3 moves to the avoidance position and the blocking position, the side wall of the end of the slide cover 3 contacts the top cover 1 respectively.

[0043] In some embodiments, please continue to refer to Figure 1 and Figure 2 The sliding cover 3 has a first arcuate surface 31 located at one end in the second direction. The first connecting part 22 is adapted to the first arcuate surface 31. The first connecting part 22 has a first arcuate mating surface 221 facing the first arcuate surface 31 in the second direction. The first arcuate mating surface 221 has a first protrusion 222 facing the sliding cover 3 in the second direction at the middle position in the first direction. The first protrusion 222 can contact the first arcuate surface 31 of the sliding cover 3 when the sliding cover 3 is in the blocked position, so as to avoid the first arcuate surface 31 being completely fitted with the first arcuate mating surface 221. In this way, when the sliding cover 3 is in the blocked position, the gap between the guide member 2 and the sliding cover 3 is ensured, while avoiding the sliding cover 3 from being fitted with the first arcuate mating surface 221, which would cause the guide member 2 to be scratched, thus helping to ensure the appearance of the guide member 2.

[0044] The sliding cover 3 also has a second arcuate surface 32 located at the other end in the second direction. The second connecting part 23 is adapted to the second arcuate surface 32. The second connecting part 23 has a second arcuate mating surface 231 facing the second arcuate surface 32 in the second direction. The second arcuate mating surface 231 has a second protrusion 232 facing the sliding cover 3 in the second direction at the middle position in the first direction. The second protrusion 232 can contact the second arcuate surface 32 of the sliding cover 3 when the sliding cover 3 is in the clearance position, so as to avoid the second arcuate surface 32 from being completely fitted with the second arcuate mating surface 231. In this way, when the sliding cover 3 is in the clearance position, the gap between the guide member 2 and the sliding cover 3 is ensured, while avoiding the sliding cover 3 from being fitted with the second arcuate mating surface 231 and causing the guide member 2 to be scratched, which helps to ensure the appearance of the guide member 2.

[0045] In some embodiments, the guide member 2 can also be a rectangular frame structure, with the first connecting part 22 and the second connecting part 23 being straight segments. When the sliding cover 3 is in the blocking position and the sliding cover 3 is in the avoidance position, the first arc-shaped surface 31 at the second direction end of the sliding cover 3 makes point contact with the first connecting part 22, and the second arc-shaped surface 32 makes point contact with the second connecting part 23. This can also prevent the first arc-shaped surface 31 and the second arc-shaped surface 32 from fitting against the guide member 2 respectively, thus avoiding scratches on the guide member 2 and also helping to ensure the appearance of the guide member 2.

[0046] In some embodiments, please refer to Figure 2 The sliding cover 3 moves between a blocking position and a clearance position relative to the slide rail 21 of the guide member 2 in a second direction via the guide structure 4. The guide structure 4 includes a cooperating guide protrusion 42 and a guide groove 41. One of the guide protrusion 42 and the guide groove 41 is located on the slide rail 21 of the guide member 2, and the other is located on the sliding cover 3. In one embodiment, the guide groove 41 is located on the slide rail 21 and extends in the second direction. The opening of the guide groove 41 faces the slide cover 3 in the first direction. The guide protrusion 42 is disposed on the slide cover 3 and arranged at both ends of the slide cover 3 in the first direction. The guide protrusions 42 at both ends face away from each other in the first direction. The guide member 2 can be a wire frame structure. During the assembly of the slide cover 3 and the guide member 2, it is necessary to slightly bend the slide rail 21 so that the guide protrusion 42 of the slide cover 3 can be inserted into the guide groove 41 of the corresponding side slide rail 21. The guide member 2 can also be a separate structure of two slide rails 21. In this way, during the assembly of the slide cover 3 and the guide member 2, it is only necessary to insert the guide protrusion 42 at the end of the slide cover 3 in the first direction into the guide groove 41 of the corresponding side slide rail 21.

[0047] The guide groove 41 on the slide rail 21 not only provides guidance for the sliding cover 3, but also restricts the movement of the sliding cover 3 away from the top cover 1 through the side wall of the guide groove 41. This helps to reduce the gap between the top cover 1 and the sliding cover 3, and prevents dust or debris from entering the receiving cavity 61 through the opening 14 through the gap between the sliding cover 3 and the top cover 1 when the sliding cover 3 is in the blocked position.

[0048] In another embodiment, the guide groove 41 can also be provided on the sliding cover 3. The guide groove 41 extends in the second direction, and the guide protrusion 42 is provided in the middle position of the slide rail 21 in the second direction. The guide protrusion 42 cooperates with the guide groove 41, and the guide protrusion 42 can reciprocate within the guide groove 41.

[0049] In other embodiments, the guide groove 41 in the guide structure 4 can be replaced by a guide hole, which is located on the slide rail 21 and the guide protrusion 42 is located on the slide cover 3. The guide hole penetrates the slide rail 21 in the first direction.

[0050] In some embodiments, the guide protrusion 42 in the guide structure 4 is disposed on the slide cover 3. The guide groove 41 or guide hole in the guide structure 4 can be formed by the top cover 1 and the slide rail 21 of the guide member 2. For example, the slide rail 21 has a notch or groove extending in the second direction at the middle position in the second direction. After the slide rail 21 is installed on the top cover 1, the slide rail 21 and the top cover 1 form a guide hole at the notch, or the slide rail 21 and the top cover 1 form a guide groove 41 at the groove. During the process of the slide cover 3 and the slide rail 21 cooperating, it is only necessary to press the guide protrusion 42 on the slide cover 3 into the guide groove 41 or guide hole between the guide member 2 and the top cover 1 in the direction perpendicular to the first direction and the second direction during the process of fixing the guide member 2 and the top cover 1.

[0051] In some embodiments, please continue to refer to Figure 2 To prevent the sliding cover 3 from wobbling relative to the guide member 2 in the second direction, a first magnetic member 17 is installed on the top cover 1, and a second magnetic member (not shown in the figure) is installed on the sliding cover 3. The first magnetic member 17 and the second magnetic member repel each other, and the sliding cover 3 can be kept in a clearance position or a blocking position by the repulsive first magnetic member 17 and the second magnetic member. In this way, the sliding cover 3 can be prevented from shaking and blocking the opening 14 when the heating non-combustible device is in use, and the opening 14 can also be prevented from shaking and being exposed when the heating non-combustible device is in standby state.

[0052] In other embodiments, the first magnetic element 17 and the second magnetic element can be omitted. A protrusion can be provided on the bottom wall of the guide groove 41 so that the protrusion cooperates with the guide protrusion 42 in the blocking position and the avoidance position, thereby restricting the sliding cover 3 from swaying in the second direction without external force by passing over the protrusion. When the sliding cover 3 needs to switch between the blocking position and the avoidance position, an external force is applied to the sliding cover 3 so that the guide protrusion 42 on the sliding cover 3 passes over the protrusion in the guide groove 41 and moves in the guide groove 41.

[0053] In some embodiments, the first magnetic element 17 and the second magnetic element can both be mounted on the corresponding top cover 1 and sliding cover 3 by an interference fit.

[0054] In some embodiments, please refer to Figure 2 The top cover 1 has a first receiving groove 15. The opening of the first receiving groove 15 faces the first direction and the second direction perpendicular to it. The opening of the first receiving groove 15 faces the sliding cover 3. The first receiving groove 15 is located between the blocking position and the clearance position of the sliding cover 3 in the second direction. The first magnetic component 17 can be installed in the first receiving groove 15 by adhesive. A plurality of first protrusions 16 are provided on the bottom wall of the first receiving groove 15. The first protrusions 16 contact the first magnetic component 17. The first magnetic component 17 and the top cover 1 form a second adhesive space between two adjacent first protrusions 16. The adhesive can be located in the second adhesive space, which can reduce the probability of adhesive overflowing from the first receiving groove 15 during the installation of the first magnetic component 17, and can also increase the contact area between the adhesive and the first magnetic component 17 and the groove wall of the first receiving groove 15, thereby improving the connection strength and connection stability between the first magnetic component 17 and the top cover 1.

[0055] In some embodiments, the sliding cover 3 has a second receiving groove (not shown in the figure). The opening of the second receiving groove faces the perpendicular second direction and the first direction, and the opening of the second receiving groove faces the top cover 1. The second receiving groove is located in the middle position of the sliding cover 3 in the second direction. The second magnetic component can be installed in the second receiving groove by adhesive. A plurality of second protrusions are provided on the bottom wall of the second receiving groove. The second protrusions contact the second magnetic component. The second magnetic component and the sliding cover 3 form a third adhesive space between two adjacent second protrusions. The adhesive can be located in the third adhesive space, which can reduce the probability of adhesive overflowing from the second receiving groove during the installation of the second magnetic component, and can also increase the contact area between the adhesive and the second magnetic component and the groove wall of the second receiving groove, thereby improving the connection strength and connection stability between the second magnetic component and the sliding cover 3.

[0056] This application also discloses a heat-not-burning device, which includes a device body 6 and a dust cover assembly as described in any of the above embodiments. The dust cover assembly is connected to the device body 6, and the top cover 1 in the dust cover assembly is connected to the shell 62 in the device body 6 to form the outer shell of the entire heat-not-burning device. The device body 6 has a receiving cavity 61, and the receiving cavity 61 corresponds to and communicates with the opening 14 on the top cover 1 in the vertical first direction and the vertical second direction. When the sliding cover 3 moves to the clearance position relative to the slide rail 21, the aerosol product can be inserted into the receiving cavity 61 of the heat-not-burning device through the opening 14. In the standby state of the heat-not-burning device, the sliding cover 3 can move to the blocking position relative to the slide rail 21 to prevent external dust or debris from entering the receiving cavity 61 along the opening 14 and affecting the subsequent use of the heat-not-burning device.

[0057] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
