Referring to figure 1, embodiments of the present application provide an aerosol-generating device 100 for heating an aerosol-generating substrate to produce an aerosol for use by a user. Wherein the heating means may be convection, conduction, radiation, or a combination thereof. The aerosol-generating substrate is preferably in the form of a columnar solid. The aerosol generating substrate includes, but is not limited to, materials for medical, health, cosmetic purposes, e.g., the aerosol generating substrate is a plant-based material, such as roots, stems, leaves, flowers, buds, seeds, etc. of a plant.

The aerosol-generating device 100 includes a main housing 10, and in the following embodiments, the main housing 10 has a cylindrical structure with a rectangular cross section, a width direction of the main housing 10 is a first direction (i.e., an X direction in fig. 1), a length direction of the main housing 10 is a second direction (i.e., a Z direction in fig. 1), and a thickness direction of the main housing 10 is a third direction (i.e., a Y direction in fig. 1).

Further, as shown in fig. 2 to 5, the main housing 10 has an accommodating cavity 12 and a mounting cavity 14, the mounting cavity 14 is located at one end of the main housing 10 in the second direction, and one side of the mounting cavity 14 communicates with one end of the main housing 10 in the second direction to form a communication port 141 for communicating with the external environment. Hold chamber 12 and be located the one end that the communication port 141 was kept away from to installation cavity 14 and be located main casing body 10 in one side on the first direction on the second direction, hold the one end intercommunication installation cavity 14 of chamber 12, the other end that holds chamber 12 extends towards the direction of keeping away from installation cavity 14 along the second direction. In this way, an end of the aerosol-generating substrate may be inserted into the receiving cavity 12 from the communication opening 141 through the mounting cavity 14 in the second direction.

In order to avoid that the communication port 141 allows foreign matter to enter the accommodation chamber 12 to affect the service life of the aerosol-generating device 100, the aerosol-generating device 100 of the present application further includes a movable cover 20 coupled to the main housing 10, and the movable cover 20 is movable in a first direction relative to the main housing 10 to switch between a cover-closing position and a cover-opening position. As shown in fig. 2, when the movable lid 20 is located at the lid closing position, the movable lid 20 covers and is lower than or flush with the communication port 141 of the installation cavity 14. As shown in figure 5, when the moveable lid 20 is in the uncapped position, the moveable lid 20 is misaligned with the communication port 141 to expose the communication port 141 so that the aerosol-generating substrate can be inserted into the receiving cavity 12 through the mounting cavity 14 via the communication port 141.

The aerosol-generating device 100 can effectively prevent dust and impurities from entering the accommodating cavity 12 through the arrangement of the movable cover 20, so that the service life of the aerosol-generating device 100 is prolonged. Moreover, since the movable lid 20 in the closed position is lower than or flush with the communication port 141 of the accommodation chamber 12, a high aesthetic level is obtained, and the movable lid 20 can be prevented from being damaged by an impact force when dropped.

In order to switch the movable lid 20 between the lid-closing position and the lid-opening position, the movable lid 20 in the lid-closing position may be moved in the second direction to pass through the unlock position to the switch position, and then moved in the first direction to the lid-opening position.

Specifically, as shown in fig. 2, when the movable cover 20 is located at the cover closing position, the movable cover 20 is flush with the communication port 141 of the accommodation chamber 12 and fixed relative to the main casing 10 in the first direction, thereby maintaining a state of shielding the communication port 141. In other embodiments, the movable cover 20 may be recessed inward relative to the main housing 10 below the communication port 141. As shown in fig. 3, when the movable cover 20 is in the unlocked position, the movable cover 20 is retracted into the accommodating chamber 12 and is movable in the second direction relative to the main housing 10 to be switchable to the switching position. As shown in fig. 4, when the movable cover 20 is at the switching position, the movable cover 20 protrudes out of the communication port 141 of the accommodation chamber 12 and is movable in the first direction relative to the main casing 10 to switch to the open cover position. When the movable lid 20 is in the uncapped position, the movable lid 141 is higher than the communication port 141 and is misaligned with the communication port 141 in the second direction, so that the aerosol-generating substrate can be inserted into the accommodation chamber 12 through the mounting chamber 14 through the communication port 141. It will be appreciated that the removable cover 20 in the uncapped position may be completely misaligned with the communication port 141 in the second direction to fully expose the communication port 141, and may also shield a portion of the communication port 141, as long as it allows for smooth insertion of the aerosol-generating substrate into the receiving chamber 12.

Further, the aerosol-generating device 100 further includes a mounting bracket 40, the mounting bracket 40 is disposed in the mounting cavity 14 and is movable relative to the mounting bracket 40 along a first direction, one side of the mounting bracket 40 in the first direction is provided with a mounting groove for mounting the movable cover 20, and the other side of the mounting bracket 40 in the first direction is provided with a fixing post for fixing the torsion spring 50.

The movable cover 20 includes a mounting portion 21 and a covering portion 23 connected to one end of the mounting portion 21. The mounting part 21 is inserted into the mounting groove of the mounting bracket 40, and the mounting part 21 can move synchronously with the mounting bracket 40 along a first direction to switch between a switching position and an uncovering position and can also move reciprocally relative to the mounting bracket 40 along a second direction to switch between a covering position, an unlocking position and a switching position. The cover portion 23 protrudes out of the mounting groove of the mounting bracket 40 in the second direction, and the shape of the cover portion 23 matches the shape of the communication port 141 of the main casing 10. When the movable cover 20 is in the closed position, the outer edge of the covering portion 23 is tightly attached to the inner side wall of the communication port 141, and the end surface of the covering portion 23 away from the mounting portion 21 is flush with the end surface of the main housing 10 where the communication port 141 is opened, so that the end surface of the main housing 10 where the communication port 141 is provided forms a complete plane. When the movable cover 20 is at the switching position, the cover portion 23 protrudes out of the communication port 141 in the second direction, and the dimension of the mounting portion 21 in the second direction is smaller than the length of the communication port 141 in the first direction, so that the movable cover 20 is movable in the second direction.

The aerosol-generating device 100 further includes a torsion spring 50, one end of the torsion spring 50 is sleeved on the fixing column of the mounting bracket 40, and the other end of the torsion spring 50 is limited to the main housing 10. The torsion spring 50 is used to apply a force to the mounting bracket 40 so that the movable lid 20 mounted to the mounting bracket 40 is alternatively located at the switching position or the lid opening position without staying at an intermediate transition position between the switching position and the lid opening position. When the movable lid 20 is switched from the switching position to the open lid position, the torsion spring 50 applies a tensile force to the movable lid 20 to cause the movable lid 20 to have a tendency to move toward the open lid position. When the movable lid 20 is switched from the lid opening position to the switching position, the torsion spring 50 applies a tensile force to the movable lid 20 to have a tendency to move the movable lid 20 toward the switching position.

In some embodiments, the aerosol-generating device 100 further comprises a resilient member 60 and a fastener 70. The fastening member 70 is formed of a screw, one end of the fastening member 70 is inserted into the mounting portion 21 of the movable cover 20, and the other end of the fastening member 70 extends out of the mounting portion 21 and penetrates through the mounting bracket 40 to extend into the accommodating chamber 12. The elastic element 60 is formed by a compression spring or other elastically deformable components, one end of the elastic element 60 is limited at one end of the fastening element 70 extending into the accommodating cavity 12, and the other end of the elastic element 60 abuts against one end face of the mounting bracket 40 facing the accommodating cavity 12, so as to apply an acting force to the movable cover 20 facing the communication port 141 along the second direction.

In the closed position, the movable lid 20 can be kept in the closed position by the elastic member 60. The elastic member 60 further stores elastic potential energy during the process of switching the movable lid 20 from the lid closing position to the unlocking position. In the process of switching the movable cover 20 from the unlock position to the switching position, the elastic member 60 releases the elastic potential energy to push the movable cover 20 to protrude out of the communication port 141.

As shown in fig. 8, one of the mounting bracket 40 and the movable cover 20 is provided with a limiting portion, the other of the mounting bracket 40 and the movable cover 20 is fixedly connected to one end of the limiting member 80, and the other end of the limiting member 80 is limited to the limiting portion, so that the movable cover 20 is located at a cover closing position, an unlocking position, or a switching position.

A first limiting protrusion 212 is convexly arranged on the bottom wall of the first limiting groove 211, and the first limiting protrusion 212 is located in the middle area of the bottom wall of the first limiting groove 211. A supporting surface 212a for supporting the limiting element 80 is formed on a side surface of the first limiting protrusion 212 close to the covering portion 23, a side of the first limiting protrusion 212 away from the covering portion 23 and a side wall of the first limiting groove 211 define together to form a first sliding slot 213 and a second sliding slot 214, the first sliding slot 213 and the second sliding slot 214 are substantially arranged in a V shape, and an end of the first sliding slot 213 away from the first limiting protrusion 212 is connected to an end of the second sliding slot 214 away from the first limiting protrusion 212 (see fig. 12 and 13).

Referring to fig. 7, a second limiting groove 215 is disposed on the other side surface of the mounting portion 21 of the movable cover 20 in the third direction, and a bottom wall of the second limiting groove 215 is perpendicular to the third direction. The bottom wall of the second limit groove 215 is convexly provided with a second limit bulge 216 and a third limit bulge 217. The second stopper protrusion 216 is located in the middle region of the bottom wall of the second stopper groove 215, the third stopper protrusion 217 is disposed at a distance from the second stopper protrusion 216 and located on the side of the second stopper groove 215 close to the covering portion 23, and the third stopper protrusion 217 forms a first guide surface 322 extending obliquely with respect to the second direction toward the side of the second stopper protrusion 216. One side of the second limiting protrusion 216 away from the third limiting protrusion 217 and the side wall of the second limiting groove 215 define together to form a first sliding groove 213 and a second sliding groove 214, the first sliding groove 213 and the second sliding groove 214 are arranged in a substantially V-shaped manner, and one end of the first sliding groove 213 away from the second limiting protrusion 216 is connected with one end of the second sliding groove 214 away from the second limiting protrusion 216. A second guide surface 216a is formed on a side of the second stopper protrusion 216 close to the third protrusion, and the second guide surface 216a extends obliquely with respect to the second direction (see fig. 13 and 15).

Specifically, referring to fig. 8 and 9, when the movable lid 20 is at the lid closing position, the elastic element 60 applies a pushing force to the movable lid 20 away from the accommodating cavity 12, and the limiting element 80 abuts against the abutting surface 212a in the second direction to prevent the movable lid 20 from moving in a direction away from the accommodating cavity 12, so that the movable lid 20 is kept at the lid closing position.

Referring to fig. 10 and 11, in the process that the movable cover 20 is switched from the cover closing position to the unlocking position, the user applies a pressure to the movable cover 20 toward the accommodating cavity 12, the elastic member 60 stores elastic potential energy, one end of the limiting member 80 slides along the first guide surface 322, and since the first guide surface 322 extends obliquely relative to the second direction, one end of the limiting member 80 is away from the abutting surface 212a in the first direction and is separated from the abutting surface 212a.

Referring to fig. 12 and 13, in the process of switching the movable cover 20 from the unlocking position to the switching position, the pressure applied to the movable cover 20 by the user disappears, the elastic element 60 releases the elastic potential energy, the movable cover 20 moves in the direction away from the accommodating cavity 12 to extend out of the communication port 141, and one end of the limiting element 80 slides along the first sliding slot 213 to one end of the first limiting slot 211 connected to the second limiting slot 215.

The two limiting members 80 are respectively located on two opposite sides of the mounting portion 32 in a radial direction, one end of each limiting member 80 is fixedly connected to the mounting bracket 40, and the other end of each limiting member 80 is limited to the limiting portion.

Thus, the movable cover 30 at the cover closing position can linearly move along the second direction and simultaneously rotate around the central axis thereof, so that the matching between the limiting part and the limiting part 80 is realized.

Specifically, when the movable cover 30 is in the closed position, the elastic element 60 applies a pushing force on the movable cover 30 away from the accommodating cavity 12, and the limiting element 80 abuts against the abutting surface 321 in the second direction to stop the movable cover 30 from moving in a direction away from the accommodating cavity 12, so that the movable cover 30 maintains the closed position.

In the process that the movable cover 30 is switched from the cover closing position to the unlocking position, the user applies pressure to the movable cover 30 towards the accommodating cavity 12, the elastic member 60 stores elastic potential energy, one end of the limiting member 80 slides along the first guide surface 322, and since the first guide surface 322 extends obliquely relative to the second direction, the movable cover 30 rotates around the rotation axis relative to the limiting member 80 while moving towards the direction close to the accommodating cavity 12, and one end of the limiting member 80 is far away from the abutting surface 321 in the first direction and is separated from the abutting surface 321.

In the process of switching the movable cover 30 from the unlocking position to the switching position, the pressure applied to the movable cover 30 by the user disappears, the elastic member 60 releases the elastic potential energy, the movable cover 30 rotates around the rotation axis while moving in the direction away from the accommodating cavity 12, and one end of the limiting member 80 slides along the first sliding groove 323 to one end of the first sliding groove 323 connected to the second sliding groove 324.

In the process of switching the movable cover 30 from the switching position to the unlocking position, the user applies pressure to the movable cover 30 toward the accommodating cavity 12, the elastic member 60 stores elastic potential energy, the movable cover 30 rotates around the rotation axis while moving in the direction close to the accommodating cavity 12, and one end of the limiting member 80 slides from one end of the second sliding groove 324 connected with the first sliding groove 323 to the other end of the second sliding groove 324.

In the process of switching the movable cover 30 from the unlocking position to the closing position, the pressure applied to the movable cover 30 by the user disappears, the elastic member 60 releases the elastic potential energy, the movable cover 30 rotates around the rotation axis while moving in the direction away from the accommodating cavity 12, and the limiting member 80 slides along the second guide surface 325 toward the abutting surface 321 until abutting against the abutting surface 321 again.

As shown in fig. 19 and 20, in some other embodiments, the covering portion 34 and the mounting portion 32 of the movable cover 30 are separately provided, and the mounting portion 32 is rotatably coupled to one end of the covering portion 34 around a rotation axis. Since the cover 34 is fitted to the stopper 80 via the pivotable attachment portion 32, the cover 34 does not pivot when the cover 34 is pushed, and therefore, the cover 34 does not need to be shaped like a rotating body to facilitate pivoting.

Further, in some embodiments, in order to facilitate manufacturing of the movable cover 30, the covering portion 34 is composed of a first body 341 and a second body 343, one end of the second body 343 is inserted into the first body 341 and fixed by a screw, and the other end of the second body 343 is opened with a mounting hole to be rotatably connected with the mounting portion 21. It will be appreciated that in other embodiments, the cover portion 34 may be an integral structure that directly mates with the mounting portion 21.

The aerosol generating device 100 shields the accommodating cavity 12 through the movable cover 20/30 to prevent dust and impurities from entering the accommodating cavity 12, and the service life of the aerosol generating device 100 is effectively prolonged. More importantly, since the movable lid 20/30 is lower than or flush with the communication opening 141 when in the closed position and extends out of the communication opening when it is required to switch to the open position, damage to the movable lid 20/30 when the aerosol-generating device 100 is dropped can be prevented and the overall aesthetic appeal of the aerosol-generating device 100 is improved. In addition, since the movable cover 20/30 is protruded out of the communication port 141 by pressing, a hand-clasping space for clasping the movable cover 20/30 is not required.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent application shall be subject to the appended claims.
