Description

Technical Field

[0001] The present invention belongs to the technical field of aerosol generating devices, and particularly relates to a tobacco extraction mechanism and an aerosol generating device. Background Art

[0002] Existing heat-not-burn smoking devices include a main body and an atomization device mounted on the main body. The atomization device includes a housing and a tobacco extraction device for storing tobacco sticks. The tobacco extraction device is mounted in the housing and can only be operated by an operation button provided outside the housing. For example, when a user takes out a tobacco stick, the operation button of the tobacco extraction device needs to be lifted before the tobacco stick can be taken out from the tobacco extraction device. This is not only inconvenient for taking out the tobacco, but also the structure of the tobacco extraction device is complex. Summary of the Invention

[0003] An object of the present invention is to provide a tobacco extraction mechanism and an aerosol generating device, so as to overcome the drawback that the operation of taking out a tobacco stick through a tobacco extraction device is relatively complex.

[0004] To achieve the above object, on the one hand, the present invention provides a tobacco extraction mechanism mounted on a housing of an aerosol generating device, including:

[0005] A fixed seat, which is movably disposed up and down in the housing. The fixed seat is provided with a receiving cavity for accommodating an aerosol matrix, and a sliding groove communicating with the receiving cavity is formed on an outer peripheral wall of the fixed seat; and

[0006] A clamping mechanism, including a top seat and a clamping member. The clamping member is provided with a rotating end and a clamping end. The rotating end is rotatably disposed on the top seat, and the clamping end can extend into the receiving cavity through the sliding groove;

[0007] Wherein, when the aerosol matrix is inserted into the receiving cavity to drive the sliding groove to move downward, the sliding groove can drive the clamping end to rotate downward and extend into the receiving cavity to clamp the aerosol matrix. When the aerosol matrix is pulled out of the receiving cavity to drive the clamping end to rotate upward, the clamping end moves away from the receiving cavity to release the aerosol matrix.

[0008] Preferably, in the above technical solution, a limiting bracket is further included. A first limiting portion is convexly provided on an outer peripheral wall of the fixed seat. The limiting bracket is disposed above the first limiting portion. When the fixed seat moves upward, the first limiting portion can abut against the limiting bracket.

[0009] Preferably, in the above technical solution, the top seat is provided with a second limiting portion. When the fixed seat moves downward, the first limiting portion can abut against the second limiting portion.

[0010] Preferably, in the above technical solution, the first limiting portion is provided with a first magnetic connector, and the limiting bracket is provided with a second magnetic connector adapted to the first magnetic connection.

[0011] Preferably, in the above technical solution, there are a plurality of the clamping members, and the plurality of the clamping members are evenly arranged on the periphery of the accommodating cavity, and the peripheral wall of the fixing seat is provided with sliding grooves corresponding to each of the clamping members.

[0012] Preferably, in the above technical solution, the rotating end of the clamping member is a rotating shaft, the clamping end has at least one tooth opening, and the rotating shaft is rotatably disposed on the top seat.

[0013] Preferably, in the above technical solution, the rotating end of the clamping member is an axial hole, the clamping end has at least one tooth opening, and the axial hole is rotatably provided on the top seat through a rotating shaft.

[0014] Preferably, in the above technical solution, the top seat is provided with a hinge portion, the top of the hinge portion is provided with a hinge groove with an open upper end, the rotating end of the clamping member is hinged to the hinge groove, and the hinge groove is provided with an avoidance groove that matches the partial position of the clamping member when the rotating end of the clamping member rotates downward to a preset distance.

[0015] Preferably, in the above technical solution, a stopper is provided at the upper end of the slide groove, and an inclined surface inclined toward the accommodating cavity is provided at the lower end of the slide groove.

[0016] To achieve the above object, in another aspect, the present invention provides an aerosol generating device, comprising the above-mentioned cigarette providing mechanism.

[0017] Compared with the existing technology, the present invention has the following beneficial effects:

[0018] 1. When inserting and removing cigarettes, the present invention inserts the cigarette into the bottom of the accommodating cavity, continues to push the cigarette to drive the accommodating cavity to move downward, and the slide groove in the accommodating cavity drives the clamping end of the clamping member to move downward to squeeze the side of the cigarette to clamp the cigarette; on the contrary, when the cigarette is pulled out of the accommodating cavity, the clamping end of the clamping member is driven by the cigarette to move upward, and when it moves to a certain distance, the clamping end is separated from the cigarette, so that the cigarette can be pulled out smoothly. In this way, the cigarette lifting mechanism is driven to move by the cigarette, which is not only simple in structure but also easy to operate, and the cigarette can be taken out without adding unnecessary actions.

[0019] 2. In order to prevent the accommodating cavity from falling after the cigarette is pulled out, the present invention introduces a magnetic suction method to adsorb the accommodating cavity onto the limiting bracket, so that the clamping end of the clamping piece is always located outside the accommodating cavity, so as not to hinder the reinsertion of the cigarette, making the cigarette insertion smoother.

[0037] As Figure 1 and Figure 4 shown, a smoke lifting mechanism in this embodiment is installed in the housing 1 of the aerosol generating device, and includes a fixed seat 3, a clamping mechanism 2 and a limiting bracket 4. The fixed seat 3 is provided with a receiving cavity 31 extending out of its upper end, and a perforation for inserting a heating component 5 of the aerosol generating device is provided in the receiving cavity 31. The receiving cavity 31 is mainly used for receiving an aerosol matrix (i.e., a cigarette 6). In this embodiment, heat dissipation holes 35 may also be provided on the side wall of the receiving cavity 31 near the bottom. Providing the heat dissipation holes 35 can make the heat generated when the cigarette is heated dissipate more easily, thereby more quickly reducing the temperature of the housing 1 of the aerosol generating device. Continuing to refer to Figure 4 、 Figure 5 and Figure 6 , the fixed seat 3 is arranged in the housing 1 in a manner that it can move up and down a certain distance. A sliding groove 32 communicating with the receiving cavity 31 is provided on the upper part of the outer peripheral wall of the fixed seat 3. The clamping mechanism 2 includes a clamping member 21 and a top seat 22. The top seat 22 is arranged in the housing 1 outside the upper part of the receiving cavity 31. The clamping member 21 is provided with a rotating end 211 and a clamping end 212. The rotating end 211 is rotatably arranged on the top seat 22, and the clamping end 212 can pass through the sliding groove 32 and extend into the receiving cavity. Among them, in the initial state, the fixed seat 3 is located at the uppermost part of the moving stroke. At this time, the clamping end 212 of the clamping member 21 abuts against the sliding groove 32 and is located outside the receiving cavity 31. When a cigarette 6 is inserted into the receiving cavity 31 of the fixed seat 3 and drives the sliding groove 32 to move downward, the sliding groove drives the clamping end 212 of the clamping member 21 to rotate downward and extend into the interior of the receiving cavity 31. The clamping end 211 of the clamping member 21 extending into the interior of the receiving cavity 31 clamps on the side wall of the cigarette 6, thereby clamping the cigarette 6 tightly in the receiving cavity 31. At this time, the cigarette 6 is inserted into the heating component 5 of the aerosol generating device. When the cigarette 6 is taken out, when the cigarette 6 is pulled out of the receiving cavity 31 of the fixed seat 3 and drives the clamping end 212 of the clamping member 21 to rotate upward, the clamping end 211 of the clamping member 21 moves away from the receiving cavity 31, thereby loosening the cigarette 6 and enabling the cigarette 6 to be smoothly pulled out. Through the insertion and extraction of the cigarette 6, the actions of lifting and clamping the cigarette can be performed. It is not only simple in structure but also convenient to operate.

[0038] It can be understood that in the initial state, the fixed seat 3 is located at the uppermost part of the moving stroke. If it is in a vertical state, the fixed seat 3 may fall to the lowermost part of the moving stroke due to its own gravity, making it impossible to perform the cigarette inserting action. At this time, during operation, the aerosol generating device can be placed upside down first to make the fixed seat 3 located at the uppermost part of the moving stroke, and then the aerosol generating device is placed flat and then the cigarette 6 can be inserted. Of course, this embodiment is not limited thereto, and other more preferable structural settings are also introduced in the following embodiments. See the following for further elaboration.

[0039] Optionally, referring to Figure 4 , to facilitate the up and down movement of the clamping end 212 of the clamping member 21 at the sliding groove 32, a stop portion is provided at the upper end of the sliding groove 32, that is, the stop surface (not shown in the figure) at the upper end of the sliding groove 32. For example, when the receiving cavity 31 of the fixed seat 3 moves downward, the stop surface at this place of the sliding groove 32 is more likely to press the clamping end 212 of the clamping member 21, making the clamping end 212 more likely to move downward. Correspondingly, an inclined surface 321 inclined toward the receiving cavity 31 is provided at the lower end of the sliding groove 32. For example, when the clamping end 212 of the clamping member 21 is located outside the sliding groove 32, the clamping end 212 is more likely to enter the receiving cavity 31 of the fixed seat 3 along this inclined surface 321.

[0040] Continuing to refer to Figure 1 , in this embodiment, optionally, there may be multiple clamping members 21, and the multiple clamping members 21 are uniformly arranged on the outer periphery of the receiving cavity 31, and sliding grooves 32 corresponding to each clamping member 21 are provided on the outer peripheral wall of the fixed seat 3. The clamping ends 212 of the multiple clamping members 21 jointly form a clamping space for clamping the cigarette 6. When the clamping ends 212 of the multiple clamping members 21 approach each other, the outer peripheral wall of the cigarette 6 is clamped, and when the clamping ends 212 of the multiple clamping members 21 move away from each other, the outer peripheral wall of the cigarette 6 is released. The cigarette 6 is clamped by the clamping ends 212 of the multiple clamping members 21, and the clamping effect is better.

[0041] It can be understood that in this embodiment, the clamping member 21 can be in the form of a sheet or a hook. Of course, it is not limited thereto, and other forms of clamping members 21 can also be used. Correspondingly, the clamping end 212 of the clamping member 21 has at least one tooth opening or a hook body. Of course, other forms such as an arc-shaped clamping opening can also be used. Further, the rotating end 211 of the clamping member 21 can be set in various forms. For example, as Figure 2a shown, the rotating end 211 of the clamping member 21 is set as a rotating shaft, and the clamping member 21 can be rotated by being hinged to the top seat 22 through the rotating shaft. Another example is Figure 2bAs shown in the figure, the rotating end 211 of the clamping member 21 is provided with a shaft hole. The shaft hole is rotatably arranged on the top seat 22 through a rotating shaft 213. At the same time, the shaft hole can be rotatably connected to the rotating shaft 213. The rotating shaft 213 can be fixedly connected or rotatably connected to the top seat 22. When there are rotational connections between the shaft hole and the rotating shaft 213 and between the rotating shaft 213 and the top seat 22, even if one of the connections between the shaft hole and the rotating shaft and between the rotating shaft and the top seat cannot rotate, it does not affect the rotation of the clamping member.

[0042] Correspondingly, referring to Figure 3 , the top seat 22 is provided with a hinge portion 221. The top of the hinge portion 221 is provided with a hinge groove 2211 with an open upper end. The rotating end 211 of the clamping member 21 is hinged to the hinge groove 2211. It can be understood that the distance between the openings at the upper end of the hinge groove 2211 is smaller than the diameter of the hinge groove 2211, so that the rotating end 211 of the clamping member 21 can be limited within the hinge groove 2211. The hinge groove 2211 is provided with an avoidance groove 2212 that matches a part of the clamping member 21 when the rotating end 211 of the clamping member 21 rotates downward to a preset distance. At this time, a 90° angle is formed between the clamping member 21 and the side wall of the cigarette rod 6. At this time, the clamping space formed by the clamping end 212 of the clamping member 21 is the smallest, so that the force for clamping the cigarette rod 6 is the largest, and thus the cigarette rod 6 can be clamped more stably.

[0043] In this embodiment, in order to enable the fixed seat 3 to move up and down within the housing 1 by a certain distance, specifically, referring to Figure 1 , Figure 5 and Figure 6 , a limiting bracket 4 is provided above the accommodation cavity 31 of the fixed seat 3. A first limiting portion 33 protrudes from the outer peripheral wall of the upper part of the fixed seat 3. Correspondingly, the first limiting portion 33 is a protrusion protruding in the opposite direction of the side wall of the fixed seat 3. When the first limiting portion 33 moves upward, it can abut against the position of the limiting bracket 4 corresponding to the upper part of the first limiting portion 33. Preferably, the limiting bracket 4 can be set in a ring shape, and the first limiting portion 33 can be arranged at a position close to the lower end of the upper end of the fixed seat 3, so that a part of the upper end of the accommodation cavity 31 can pass through the middle hole of the ring-shaped limiting bracket 4, and the first limiting portion 33 abuts against the periphery of the ring-shaped limiting bracket 4. This setting not only enables the first limiting portion 33 to be aligned with the periphery of the limiting bracket 4 regardless of its position, but also because a part of the upper end of the accommodation cavity 31 passes through the middle hole of the ring-shaped limiting bracket 4, a smaller space can be used to achieve the maximum upward movement stroke. Further, referring to Figure 4, the top seat 22 is provided with a second limiting portion 222. When the fixing seat 3 moves downward, the first limiting portion 33 can abut against the second limiting portion 222. Specifically, the second limiting portion 222 is a limiting groove formed above the top seat 22. When the fixing seat 3 moves downward, the second limiting portion 333 can be directly sleeved in this limiting groove, thereby preventing the fixing seat from continuing to move downward. Thus, the up-and-down movement distance of the fixing seat 3 is formed by the limiting distance between the top seat 22 and the limiting bracket 4, so that the fixing seat 3 can move up and down a certain distance within the outer shell 1.

[0044] It can be understood that the number of the first limiting portion 33 and the second limiting portion 222 can be designed and selected according to needs, and can be one group or several groups, which is not limited in this embodiment. Moreover, when the scheme of several groups of the first limiting portion 33 and the second limiting portion 222 is selected, the stress parts of the fixing seat 3 abutting against the limiting bracket 4 can be more, so that the stress on the limiting bracket 4 is more uniform and not easily damaged.

[0045] Furthermore, continue to refer to Figure 1 , in order to make it more convenient to insert the cigarette stick 6 again in this embodiment, the fixing seat 3 must be locked when moving upward to the maximum. Therefore, a first magnetic connecting member 34 is provided on the first limiting portion 33, and the limiting bracket 4 is provided with a second magnetic connecting member 41 adapted to the first magnetic connection 34, so that when the fixing seat 3 rises to the maximum distance, the first magnetic connecting member 34 and the second magnetic connecting member 41 can be attracted to each other. At this time, the fixing seat 3 can be locked at the maximum upward position, and the clamping end 212 of the clamping member 21 is also located outside the accommodating cavity 31, so that when the cigarette stick 6 is inserted next time, it can be directly inserted. Specifically, in this embodiment, grooves 331 are formed at the corresponding parts of the first limiting portion 33 and the limiting bracket 4, and the first magnetic connecting member 34 and the second magnetic connecting member 41 are respectively fixed in the corresponding grooves 331. Preferably, the first magnetic connecting member 34 and the second magnetic connecting member 41 are suction magnets. Optionally, the number of the first magnetic connecting member 34 and the second magnetic connecting member 41 can be selected according to needs, and can be one group or several groups. If there are several groups, the locking effect of the fixing seat 3 is better.

[0046] Finally, refer to Figure 5 and Figure 6, a specific embodiment with four clamping members 21 is disclosed. In the initial state, the fixed seat 3 is magnetically attracted to the second magnetic connecting member 41 of the limiting bracket 4 through the first magnetic connecting member 34. The clamping ends 212 of the clamping members 21 are located at the sliding grooves 32 outside the accommodating cavity 31. When a cigarette 6 is inserted into the bottom of the accommodating cavity 31 of the fixed seat 3 and then continues to drive the sliding groove 32 to move downward, the four sliding grooves 32 of the accommodating cavity 31 respectively drive the clamping ends 212 of the four clamping members 21 to rotate downward and extend into the interior of the accommodating cavity 31. The clamping ends 212 of the four clamping members 21 extending into the interior of the accommodating cavity 31 clamp on the side wall of the cigarette 6. When the clamping ends 212 of the four clamping members 21 are perpendicular to the side wall of the cigarette 6, the cigarette 6 is clamped tightly in the accommodating cavity 31, and the cigarette 6 is also inserted into the heating component 5 of the aerosol generating device. When the cigarette 6 is taken out, when the cigarette 6 is pulled out of the accommodating cavity 31 of the fixed seat 3 and drives the clamping ends 212 of the four clamping members 21 to rotate upward, the clamping ends 212 of the four clamping members 21 move away from the accommodating cavity 31, thereby loosening the cigarette 6 and enabling the cigarette 6 to be smoothly pulled out. The fixed seat 3 is magnetically attracted to the second magnetic connecting member 41 of the limiting bracket 4 again to facilitate the insertion of the next cigarette 6.

[0047] The present invention provides an aerosol generating device, including the cigarette lifting mechanism as described above.

[0048] When the present invention performs the operation of inserting and pulling out the cigarette, the cigarette is inserted into the bottom of the accommodating cavity, and the cigarette is continuously pushed to drive the accommodating cavity to move downward. The sliding groove in the accommodating cavity drives the clamping end of the clamping member to move downward to squeeze the side of the cigarette to clamp the cigarette; on the contrary, when the cigarette is pulled out of the accommodating cavity, the clamping end of the clamping member is driven by the cigarette to move upward. When it moves a certain distance, the clamping end disengages from the cigarette, so that the cigarette can be smoothly pulled out. Thus, by driving the cigarette lifting mechanism to act through the cigarette, not only is the structure simple, but also the operation is convenient, and the cigarette can be taken out without adding extra actions.

[0049] The foregoing description of the specific exemplary embodiments of the present invention is for the purposes of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made in accordance with the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present invention, as well as various different selections and changes. The scope of the present invention is intended to be defined by the claims and their equivalents.
