As shown in fig. 1, an embodiment of the present invention provides an aerosol-generating device 100 having a rotary opening and closing mechanism 60. Next, the structure of the rotary opening and closing mechanism 60 in the present application will be described by taking as an example an aerosol-generating device 100 in which the aerosol-generating device 100 is an aerosol-generating device such as cut tobacco. The present embodiment is described as an example, and the technical scope of the present application is not limited thereto. It is understood that in other embodiments, the aerosol-generating device 100 may also be embodied as other devices that are equipped with the rotary opening and closing mechanism 60, such as an opening and closing valve, a door and a window, and the like, without limitation.

The aerosol-generating device 100 has a storage chamber 20 and an aerosol-generating chamber 40 arranged adjacent to each other, the storage chamber 20 being for storing an aerosol-generating substance, and a heating element for heating the aerosol-generating substance being provided in the aerosol-generating chamber 40 for heating the aerosol-generating substance. The rotary opening and closing mechanism 60 is arranged between the storage cavity 20 and the aerosol generating cavity 40, and a user controls the storage cavity 20 and the aerosol generating cavity 40 to be communicated or disconnected by operating the rotary opening and closing mechanism 60.

Specifically, when the aerosol-generating device 100 is not in use, the user may first store the aerosol-generating substance in the storage chamber 20, at which time the storage chamber 20 and the aerosol-generating chamber 40 are disconnected from each other by rotating the opening and closing mechanism 60, thereby preventing the aerosol-generating substance in the storage chamber 20 from entering the aerosol-generating chamber 40. When the aerosol-generating device 100 is needed to be used, the user can control the rotary opening and closing mechanism 60 to communicate the storage cavity 20 with the aerosol-generating cavity 40, and at least part of the aerosol-generating substance in the storage cavity 20 enters the aerosol-generating cavity 40 from the storage cavity 20 through the rotary opening and closing mechanism 60 due to gravity, vibration and the like. When a certain amount of aerosol product enters the aerosol-generating chamber 40, the user can control the rotary opening and closing mechanism 60 to disconnect the storage chamber 20 and the aerosol-generating chamber 40 again, the aerosol product in the aerosol-generating chamber 40 can be heated by the heating element in the aerosol-generating chamber 40, and the aerosol product is heated and atomized to generate aerosol for the user to eat. During heating, since the storage chamber 20 and the aerosol-generating chamber 40 are isolated from each other by the rotary opening and closing mechanism 60, heat in the aerosol-generating chamber 40 is not transferred to the storage chamber 20. It will be appreciated that other structures of the aerosol-generating device 100 other than the rotary opening and closing mechanism 60 are not the main inventive point of the present application and will not be described in detail here.

Referring to fig. 2, 3 and 4, the rotary opening and closing mechanism 60 includes a fixing base 61, an opening and closing component 63 and a rotating component 65, the opening and closing component 63 and the rotating component 65 are respectively coupled to the fixing base 61, and a user can control the opening and closing component 63 to open or close the storage cavity 20 and the aerosol generating cavity 40 by controlling the rotating component 65.

Specifically, the fixing base 61 has a disc-shaped structure, and includes a circular first surface and a circular second surface that are opposite and parallel to each other in the first direction. The center of the fixing base 61 is provided with a first through hole 612 communicating the first surface and the second surface, the cross section of the first through hole 612 is circular, and the central axis of the first through hole 612 coincides with the central axis of the fixing base 61 and extends along the first direction. As such, the storage chamber 20 and the aerosol-generating chamber 40 of the aerosol-generating device 100 may communicate with each other through the first communication hole 612. It is understood that the shape of the first communication hole 612 is not limited thereto, and in other embodiments, may be provided in other regular or irregular shapes as desired.

Further, a limiting rib 614 for limiting the opening and closing assembly 63 is convexly arranged on the first surface of the fixed seat 61. Specifically, the plurality of sets of limiting ribs 614 are circumferentially arranged around the first through hole 612 at intervals, each set of limiting ribs 614 includes a plurality of limiting ribs 614 arranged at intervals, each limiting rib 614 extends from the outer edge of the fixing seat 61 to the edge of the first through hole 612, and the extending direction of each limiting rib 614 is parallel to the radial direction of the first through hole 612.

Referring to fig. 2 to 4, the opening and closing assembly 63 includes at least two opening elements 632, each of the opening elements 632 is movably mounted on the first surface of the fixing base 61, and each of the opening elements 632 can move to different positions on the first surface relative to the first through hole 612, so that the opening and closing assembly 63 has an open state (as shown in fig. 7) for opening the first through hole 612 and a closed state (as shown in fig. 2) for closing the first through hole 612.

Specifically, a limiting groove 6321 matched with the limiting rib 614 on the fixing seat 61 is formed in one side of each opening element 632 facing the first surface of the fixing seat 61, and the matched limiting rib 614 and the limiting groove 6321 can slide relatively in a direction parallel to the radial direction of the first through hole 612. Thus, the opening element 632 can slide along the first communication hole 612 on the first surface of the fixing base 61.

Specifically, each opening element 632 is provided with a plurality of sets of limiting grooves 6321, each set of limiting grooves 6321 includes a plurality of limiting grooves 6321 arranged at intervals, and the extending direction of each limiting groove 6321 is parallel to the radial direction of the first through hole 612. Thus, the opening element 632 is limited by the limiting rib 614 through the limiting groove 6321, and the opening element 632 can only move along the radial direction of the first through hole 612 under the limitation of the limiting rib 614.

It can be understood that the number of the limiting ribs 614 and the limiting grooves 6321 is not limited, in other embodiments, a plurality of sets of limiting ribs may be disposed on one side of the opening-closing member 632 facing the first surface, and the first surface of the fixing base 61 is provided with a limiting groove matching with the limiting ribs.

Further, the orthogonal projection of the opening and closing member 632 on the first surface of the fixing base 61 is fan-shaped, and has two straight edges and an arc-shaped edge connecting the two straight edges. When the opening and closing assembly 63 is in the closed state, the orthographic projection of the opening and closing assembly 63 on the fixing seat 61 is approximately circular, which is concentric with the first communicating hole 612 and has a diameter larger than the first communicating hole 612, the arc-shaped edges of each opening and closing member 632 together form the outer contour of the opening and closing assembly 63, the straight edges of two adjacent opening and closing members 632 are mutually abutted, and the vertex of each opening and closing member 632 is superposed with the central point of the first communicating hole 612, so that the first communicating hole 612 is completely shielded by the opening and closing assembly 63. When the opening/closing assembly 63 is in the open state, the adjacent opening/closing members 632 are separated from each other, and an orthogonal projection of the opening/closing assembly 63 on the fixing base 61 is at least partially located outside an edge of the first through hole 612 to expose the first through hole 612.

In some embodiments, at least a portion of the edge of an opening element 632 that contacts an adjacent opening element 632 is provided with a cutting edge, specifically, one straight edge of each opening element 632 is provided with a cutting edge. As such, when the opening and closing assembly 63 is switched from the open state to the closed state, the adjacent opening and closing members 632 cooperate to perform a cutting function to cut the aerosol-generating substance in the first communication hole 612. It will be appreciated that the shape of the cutting edge is not limited and may be provided in different shapes as desired.

Referring to fig. 2 and 3, the rotating member 65 is a disc-shaped structure and includes a top wall and a side wall extending from the top wall edge of the rotating member to the same direction, the side wall of the rotating member circumferentially surrounds the top wall of the rotating member, and the inner diameter of the rotating member 65 is larger than the outer diameter of the fixing base 61 and covers the side of the fixing base 61 where the opening and closing assembly 63 is disposed. The rotor top wall of the rotor 65 is opened with a second communication hole 652 having the same shape and size as the first communication hole 612. As such, when the opening and closing member 63 is in the opened state, the second communication hole 652 is correspondingly communicated with the first communication hole 612 in the first direction.

Specifically, in some embodiments, the rotating member 65 is provided with a plurality of arc-shaped rotating grooves 654, the plurality of rotating grooves 654 are arranged at intervals around the second communication hole 652 along the circumferential direction, each rotating groove 654 includes a first stopper end 6541 and a second stopper end 6543 which are arranged opposite to each other in the rotating direction of the rotating member 65, the distance of the rotating groove 654 relative to the central axis of the first communication hole 612 gradually increases from the first stopper end 6541 to the second stopper end 6543, and each rotating groove 654 extends in a curved manner and protrudes in a direction away from the second communication hole 652.

Each opening-closing member 632 is provided with a limiting column 6323 protruding toward one side of the rotating member 65, the limiting column 6323 is close to the middle of one side of the arc-shaped edge of the opening-closing member 632, and the limiting column 6323 of each opening-closing member 632 is correspondingly limited in one rotating groove 654. When the rotating member 65 rotates in the first direction relative to the fixed base 61, the position-limiting column 6323 can move along a certain track in the rotating slot 654.

Since the distance from the first position-limiting end 6541 to the second position-limiting end 6543 of the rotating slot 654 to the second communication hole 652 is gradually increased, the rotation of the rotating member 65 around the central axis of the fixing base 61 can be converted into the linear movement of all the opening-closing members 632 along the position-limiting rib 614, thereby switching the opening-closing assembly 63 between the open state and the closed state. When the position-limiting column 6323 is limited at the first position-limiting end 6541, the distance between the position-limiting column 6323 and the central axis of the first through-hole 612 is the smallest, and the opening-closing assembly 63 is in the closed state; when the position-limiting pillar 6323 is limited at the second position-limiting end 6543, the distance between the position-limiting pillar 6323 and the central axis of the first through-hole 612 is the largest, and the opening/closing element 63 is in the open state.

Preferably, in some embodiments, the opening and closing assembly 63 includes three opening elements 632, and correspondingly, three sets of limiting ribs 614 are protruded on the first surface of the fixing base 61, each set of limiting ribs 614 is used for limiting one opening element 632, the rotating element 65 also has three rotating slots 654, and each rotating slot 654 drives one opening element 632 to rotate. Therefore, the opening and closing assembly 63 has a fast opening speed, and the adjacent opening and closing members 632 do not interfere with each other to affect the opening and closing smoothness. It is understood that the number of the opening and closing members 632, the fixing posts 614 and the rotation slots 654 is not limited thereto, and may be set as desired.

Referring to fig. 4 to 7, the process of switching the opening/closing assembly 63 from the closed state to the open state is as follows:

the user rotates the rotating member 65 in the clockwise direction, the rotating member 65 rotates continuously around the first direction with the rotation center of the central axis of the fixing base 61, and the opening member 632 moves in the direction away from the central axis of the first through hole 612 along the radial direction of the first through hole 612 under the driving of the rotating member 65 and the guiding action of the fixing base 61 until abutting against the side wall of the rotating member 65 and being unable to move continuously. At this time, the first communication hole 612 and the second communication hole 652 communicate with each other.

It can be understood that the process of switching the opening/closing assembly 63 from the open state to the closed state is opposite to the process of switching the closed state to the open state, and a user only needs to rotate the rotating member 65 in the counterclockwise direction to switch the opening/closing assembly 63 from the open state to the closed state, which is not described herein again.

In the above-mentioned rotary opening and closing mechanism 60 and the aerosol generating device 100 provided with the same, the rotary opening and closing mechanism 60 is substantially a disk-shaped structure, the volume of the rotary opening and closing mechanism 60 itself is small, and the rotary opening and closing mechanism does not occupy more space when switching between the open state and the closed state, so that the volume of the aerosol generating device 100 provided with the rotary opening and closing mechanism is not excessively increased while ensuring a sufficient opening and closing range. Moreover, the opening and closing member 632 has an effect of cutting the aerosol-generating material while achieving an opening and closing effect, and thus has a wide application range without providing an additional cutting mechanism.

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 invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
