[0032] The application will be described in further detail below with specific reference being made to the drawings in which the same or similar elements of different drawings have the same or similar reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one of ordinary skill in the art that aspects of the application can be practiced without all the specific details given below. In other instances, well-known methods have not been described in detail in order to avoid unnecessarily obscuring the application. Reference throughout this report to "various embodiments" or "one embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Therefore, appearances of the phrases "various embodiments" or "one embodiment" in various places throughout this specification are not necessarily referring to the same embodiment.

[0033] In addition, features, operations, or characteristics described in the specification can be combined in any suitable manner in various embodiments. Also, various steps or acts in a method described in the specification can be performed in a different sequence from the one described or can be performed concurrently. Therefore, the various sequences described in the specification are illustrative only and not mandatory for the practice of the application, unless otherwise specified. Other steps or acts can be provided prior to, after, or in between the steps or acts described herein.

[0034] The serial numbers of components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The "connection" and "coupling" in the application include direct and indirect connections (couplings) unless otherwise specified.

[0035] Some heat-not-burn devices are provided with a dust cover 200 at the base material insertion port 121 to prevent dust or debris from entering the heating cavity through the base material insertion port 121. The dust cover 200 is movably arranged outside the housing 100 through a sliding rail or a rotating shaft 231 parallel to the insertion direction of the aerosol substrate 700, so that the dust cover 200 can be opened and closed by sliding or rotating. Before use, the dust cover 200 is moved to expose the base material insertion port 121, so that the aerosol substrate 700 can be inserted. After the aerosol substrate 700 is pulled out, the dust cover 200 is moved back to block the base material insertion port 121.

[0036] Although such a dustproof design can play a dustproof role, it will increase the size of the heat-not-burn device and affect portability. Moreover, the user needs to actively adjust the position of the dust cover 200 during use, which increases the complexity of operation and has some shortcomings in practicality.

[0037] In the embodiments of the present application, the dust cover 200 adopts a hidden inward turning design, and can be opened and closed during the insertion and extraction of the aerosol substrate 700 without special operation. Compared with the sliding and rotating translation opening and closing mode described above, the dust cover 200 does not increase the size of the heat-not-burn device, and is not easy to produce wear marks on the shell 100, which is beneficial to maintain the appearance of the product and help to improve the practicability of the dustproof design.

[0038] In one embodiment, a heat-not-burn device is disclosed, please refer to Figures 1-6 The heat-not-burn device comprises a shell 100, a dust cover 200, an elastic member 300, and other components as needed.

[0039] Please refer to Figure 1 and Figure 2 The shell 100 can be understood as a collection of related components that constitute the basic structural framework and outer contour form of the heat-not-burn device.

[0040] Please refer to Figure 2 and Figure 3 The shell 100 is provided with a substrate insertion port 121, and the shell 100 is provided with a substrate containing cavity 130 in communication with the substrate insertion port 121. The substrate insertion port 121 is used for inserting the aerosol substrate 700 into the substrate containing cavity 130.

[0041] For example, please refer to Figure 1 , Figure 3 and Figure 4 The shell 100 comprises a main shell 110 and an end cover 120. The end cover 120 is assembled on the main shell 110 to form the substrate containing cavity 130 together with the main shell 110. The substrate insertion port 121 is arranged in the middle of the end cover 120, and the aerosol substrate 700 can be inserted into the substrate containing cavity 130 through the substrate insertion port 121. Those skilled in the art can understand that in other embodiments, the end cover 120 and the main shell 110 can also be integrally arranged, and the substrate insertion port 121 can also be arranged on the main shell 110.

[0042] Please refer to Figure 3 and Figure 4 The dust cover 200 is reversibly arranged at the substrate insertion port 121, Figure 3 The direction of the dashed arrow shown in the figure is the turning direction of the dust cover 200. The dust cover 200 has a closed position and an open position. The dust cover 200 can be turned from the closed position to the open position along the insertion direction of the aerosol substrate 700; as Figure 3 shown, when the dust cover 200 is in the closed position, the dust cover 200 blocks the substrate insertion port 121, and the outer surface of the dust cover 200 is flush with the outer wall surface of the shell 100; as Figure 4As shown, when the dust cover 200 is in the open position, the substrate insertion port 121 is open, and the aerosol substrate 700 can be inserted into the substrate receiving cavity 130 through the open substrate insertion port 121.

[0043] Please refer to Figure 4 and Figure 5 The elastic member 300 acts on the dust cover 200 to exert a force on the dust cover 200 to flip it to the closed position, so that after the aerosol substrate 700 is pulled out, the dust cover 200 can automatically flip to the closed position to seal the substrate insertion port 121, and when the aerosol substrate 700 is inserted, the dust cover 200 can be pried open by the aerosol substrate 700, without the need for additional operation, which is convenient for users to use. In different embodiments, the elastic member 300 can be at least one of a torsion spring, a compression spring, an elastic sheet, or other elastic structural elements, which can meet the design and use requirements.

[0044] Those skilled in the art can understand that the flipping arrangement of the dust cover 200 is not limited, for example, a pivot hole 230 for inserting a pivot 231 can be provided on the dust cover 200, and a pivot 231 can be provided on the housing 100 near the substrate insertion port 121, so that the dust cover 200 can be arranged to be flipped at the substrate insertion port 121 by the pivot 231; the pivot 231 can also be integrated on the dust cover 200, and a pivot hole 230 can be provided on the housing 100 near the substrate insertion port 121 to achieve the flipping arrangement of the dust cover 200; in short, any flipping arrangement that meets the design and use requirements can be used.

[0045] In order to save the space required for flipping the dust cover 200 and improve the structural compactness of the heat-not-burn device, in one embodiment, please refer to Figure 4 and Figure 5 The dust cover 200 includes a main body portion 210 and a pivot portion 220, and the main body portion 210 and the pivot portion 220 together form a pivot hole 230 for realizing the flipping of the dust cover 200. At least part of the pivot hole 230 is located in the main body portion 210, so that the flipping space required for flipping the dust cover 200 is reduced, which not only facilitates the design of the heat-not-burn device, but also helps to improve the structural compactness of the heat-not-burn device.

[0046] In order to further save the space required for flipping the dust cover 200, in one embodiment, please refer to Figure 5, the main body part 210 includes a cover part 211 and a connecting part 212, the cover part 211 is arranged corresponding to the substrate accommodating cavity 130, the connecting part 212 is arranged at the side of the cover part 211, and the rotating shaft part 220 is arranged at the connecting part 212. By arranging the connecting part 212 at the side of the cover part 211, the size of the cover part 211 can be matched with the size required for inserting the aerosol substrate 700, without expanding the size of the cover part 211 in the direction parallel to the axis of the rotating shaft hole 230 to provide the arrangement space of the rotating shaft part 220, which helps to save the width of the turnover space required for the dustproof cover 200.

[0047] For example, referring to Figure 4 and Figure 5 , the dustproof cover 200 includes the main body part 210 and the rotating shaft part 220, the main body part 210 includes the cover part 211 and the connecting part 212, the connecting part 212 is arranged at the side of the cover part 211, and the rotating shaft part 220 is arranged at the middle of the connecting part 212, the side of the connecting part 212 close to the substrate accommodating cavity 130 is arranged with the first groove 2121 corresponding to the rotating shaft part 220, the side of the rotating shaft part 220 close to the first groove 2121 is provided with the through hole 221 communicating with the first groove 2121, the through hole 221 and the part of the first groove 2121 opposite to the through hole 221 jointly form the rotating shaft hole 230, the rotating shaft 231 is inserted in the rotating shaft hole 230, and the rotating shaft 231 is arranged to pass out of the rotating shaft hole 230 along the first groove 2121, and the projection of the rotating shaft 231 in the projection of the dustproof cover 200 in the insertion direction of the aerosol substrate 700 protrudes from the projection of the connecting part 212, that is, the ends of the rotating shaft 231 protrude from the connecting part 212 along the length direction of the first groove 2121.

[0048] For example, referring to Figure 6 , the inner wall of the end cover 120 can be arranged with the connecting lug 122 on both sides of the substrate insertion port 121 in a symmetrical manner, and arranged with the second groove 123 corresponding to the first groove 2121, the lug hole 1221 communicating with the second groove 123 is arranged on the connecting lug 122, the hole wall of the lug hole 1221 and the groove wall of the second groove 123 jointly form the mounting hole for the end of the rotating shaft 231 to be rotatably inserted, so that the dustproof cover 200 can be arranged at the substrate insertion port 121 in a rotatable manner. The elastic member 300 can be a torsion spring, the torsion spring is sleeved on the rotating shaft 231, one end of the torsion spring is fixed on the inner wall of the end cover 120, and the other end is provided with the rod body part 310, the rod body part 310 abuts against the inner wall of the main body part 210 in the direction perpendicular to the axial direction of the rotating shaft 231, so as to apply a force to the dustproof cover 200 to rotate to the closed position.

[0049] In other embodiments, the dustproof cover 200 and the elastic member 300 can adopt other arrangement forms, as long as they can meet the design and use requirements.

[0050] In order to enable the dust cover 200 to be kept in the closed position, and when in the closed position, the outer surface of the dust cover 200 can be flush with the outer wall of the shell 100, so as to improve the dustproof effect and the appearance of the heat-not-burn device, in an embodiment, please refer to Figure 6 , one side of the dust cover 200 is provided with a protruding part 240, which is used to abut against the shell 100. In some embodiments, a limiting groove 124 can also be provided on the inner wall of the shell 100, so that when the dust cover 200 is in the closed position, the protruding part 240 is clamped in the limiting groove 124. Those skilled in the art can understand that the setting position and the number of the protruding part 240 are not limited, as long as they can meet the design and use requirements.

[0051] For example, the protruding part 240 is arranged on the side of the cover part 211 away from the connecting part 212, and the protruding part 240 is located on the side of the cover part 211 close to the substrate receiving cavity 130. The limiting groove 124 is correspondingly arranged on the inner wall of the end cover 120, and the length and width of the limiting groove 124 are not less than the length and width of the protruding part 240. When the dust cover 200 is flipped under the elastic force of the elastic member 300, the protruding part 240 can be clamped in the limiting groove 124, so that the dust cover 200 can be positioned at the closed position, achieving the plugging of the substrate insertion port 121, and the outer surface of the dust cover 200 can be flush with the outer wall of the shell 100.

[0052] In order to increase the difficulty of dust and other impurities entering the substrate receiving cavity 130 through the substrate insertion port 121 during use of the heat-not-burn device, in an embodiment, please refer to Figure 5 and Figure 6 The side of the cover part 211 away from the connecting part 212 has a first arc surface 2111, and the side of the connecting part 212 away from the cover part 211 has a second arc surface 2122, and the radius of curvature of each part of the second arc surface 2122 is smaller than the radius of curvature of each part of the first arc surface 2111. By arranging the first arc surface 2111 and the second arc surface 2122, the connecting part 212 is smaller than the cover part 211, and thus the area of the region of the substrate insertion port 121 opposite to the connecting part 212 is reduced. That is, when the aerosol substrate 700 is inserted into the substrate insertion port 121, the area of the exposed part of the substrate insertion port 121 is reduced, so that dust and other impurities are not easy to enter the substrate receiving cavity 130 through the substrate insertion port 121, improving the dustproof effect during use. For example, the main body part 210 can be arranged in the shape of a goose egg, the large end of the main body part 210 forms the first arc surface 2111, and the small end of the main body part 210 forms the second arc surface 2122. The first arc surface 2111 and the second arc surface 2122 can be connected by a flat surface or an arc surface.

[0053] In an embodiment, the substrate socket 121 is provided with a guide surface for guiding the insertion and removal of the aerosol substrate 700. For example, the curvature of the first curved surface 2111 can be designed in reference to the curvature of the outer wall of the aerosol substrate 700 that is matched with the heat-not-burn device. The curved surface opposite to the first curved surface 2111 at the substrate socket 121 can serve as a guide surface for guiding the insertion and removal of the aerosol substrate 700, which helps to precisely insert the aerosol substrate 700.

[0054] In an embodiment, referring to Figure 3 and Figure 4 the heat-not-burn device further comprises a heating element 400, which is arranged in the substrate accommodating cavity 130 and is spaced apart from the substrate socket 121. The spacing portion can be used as a flipping space for the dust cover 200. In order to reduce the space occupied by the spacing portion, in a further embodiment, a avoiding groove 410 can be arranged at one end of the heating element 400 close to the substrate socket 121, which is arranged in correspondence with the flipping track of the dust cover 200 to provide a flipping space for the dust cover 200.

[0055] For example, referring to Figure 4 the heating element 400 is arranged as a heating cup, the cup opening of the heating cup is arranged towards the substrate socket 121 and is spaced apart from the substrate socket 121. After the aerosol substrate 700 is inserted from the substrate socket 121, it can be inserted into the inner cavity of the heating cup through the spacing portion for heating. The avoiding groove 410 is arranged at one side of the cup opening of the heating cup. Figure 4 As shown in the perspective view, the avoiding groove 410 can be arranged below the rotating shaft portion 220, and the size of the avoiding groove 410 can be arranged to allow the protruding portion 240 to enter and exit, so as to accommodate the protruding portion 240 when the dust cover 200 is flipped to the open position.

[0056] In an embodiment, referring to Figure 3 and Figure 4 the heat-not-burn device further comprises a sealing sleeve 500, which is arranged in the substrate accommodating cavity 130 and located between the heating element 400 and the outer shell 100. The sealing sleeve 500 has a substrate passage 510, which communicates the substrate socket 121 and the substrate accommodating cavity 130 to improve the dustproof performance and prevent water vapor, dust and the like outside the heat-not-burn device from entering the heating element 400 through other openings or paths other than the substrate socket 121, which helps to improve the dustproof effect.

[0057] In an embodiment, referring to Figure 3The heat-not-burn device can further include a power supply assembly 600, which can be an electric core or a combination of an electric core and a circuit board, to supply power to electric elements such as the heating element 400 in the heat-not-burn device, and can also be used to control the heating power of the heating element 400 and the like.

[0058] The above describes the present application by using specific examples, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, those skilled in the art can make several simple deductions, deformations or substitutions.
