Description

Technical Field

[0001] The present invention relates to an aerosol generator. Background Art

[0002] Existing aerosol generators are provided with a filler slot for inserting a drawable material. However, when the user removes the drawable material, the open end of the filler slot is in an open state and is always exposed. This allows the aerosol inside the device to escape from the open end, and at the same time, dust or contaminants from the outside can enter the filler slot through the open end, causing contamination of the device. To prevent dust or contaminants from entering the filler slot through the opening, a silica gel plug or a dustproof cover is usually provided in the device. However, although the silica gel plug is easy to operate, it is easily lost; on the other hand, existing dustproof covers are usually sliding mechanisms provided outside the device, which not only affect the aesthetics of the product, but also usually have problems such as a large opening and closing stroke of the dustproof cover, making the in-place operation inconvenient.

[0003] Therefore, the prior art still needs to be improved and enhanced. Summary of the Invention

[0004] The main object of the present invention is to provide an aerosol generator, aiming to improve the convenience of operation and the stability of opening and closing of the dustproof cover.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] An aerosol generator includes an inner shell, a dustproof cover, and a sleeve shell. The inner shell is provided with a filler slot for placing a drawable material. Both ends of the dustproof cover are rotatably connected to opposite sides of the open end of the filler slot to be mounted on the open end. The sleeve shell is rotatably sleeved on the outer periphery of the inner shell. Both ends of the dustproof cover are respectively provided with gears, and the end face of the sleeve shell close to the open end is provided with a matching rack. When the sleeve shell is rotated by an external force, the rack rotates and meshes with the gears, and the gears drive the dustproof cover to rotate relative to the open end to open or close the open end.

[0007] In the aerosol generator, the dustproof cover includes a first cover body and a second cover body. The first cover body and the second cover body have the same structure, and both include a main body, a gear and a runner respectively connected to both ends of the main body. The gear and the runner are coaxially rotatably connected to both sides of the open end so that the main body is mounted on the open end. When the two gears are respectively engaged and driven with the corresponding racks, the corresponding runners are driven to rotate, so that the main bodies of the first cover body and the second cover body rotate relative to the open end to open or close the open end.

[0008] The aerosol generator, wherein the gears of the first cover and the second cover are respectively located on both sides of the open end. Correspondingly, the two racks are respectively located on both sides of the open end. When the housing rotates under an external force, the racks rotate and mesh with the corresponding gears, so that the two gears rotate in opposite directions, and drive the two bodies to separate from each other to open the open end, or to fit together to close the open end.

[0009] The aerosol generator, wherein the body has an arc-shaped plate structure. When the body of the first cover fits with the body of the second cover, a hemispherical structure adapted to the open end is formed to close the open end.

[0010] The aerosol generator, wherein a first slot is provided on the side of the body of the first cover facing the body of the second cover, and a second slot is provided on the side of the body of the second cover facing the body of the first cover. A limiting post is provided on the side wall of the open end. When the two bodies fit together, the first slot and the second slot enclose a limiting hole adapted to the limiting post, and the limiting post passes through the limiting hole.

[0011] The aerosol generator further includes an elastic damping member having at least two adjacent flanges. The elastic damping member is sleeved on the outer periphery of the inner shell and can slide along the axial direction of the inner shell. The housing is elastically pressed against one end of the elastic damping member having a flange, and a protrusion is provided and is received in any one of the flanges. When the housing is forced to rotate, the protrusion is driven to rotate and slide into another flange, so that the elastic damping member deforms and slides along the axial direction of the housing.

[0012] The aerosol generator, wherein the elastic damping member includes an elastic member and a pressing ring that are sequentially sleeved on the inner shell in the direction close to the open end. One side of the pressing ring elastically abuts against the elastic member, and the other side abuts against the housing and is provided with the at least two adjacent flanges.

[0013] The aerosol generator, wherein at least one slide rail extending in the axial direction is convexly provided on the outer periphery of the inner shell, and a matching chute is provided on the elastic damping member. The slide rail is received in the corresponding chute, so that the elastic damping member can only slide along the axial direction of the inner shell.

[0014] The aerosol generator, wherein a first limiting ring is convexly provided on the outer periphery of the inner shell, and a second limiting ring is convexly provided on the inner side wall of the housing. An annular limiting groove is formed between the first limiting ring and the second limiting ring, and the elastic damping member is received in the annular limiting groove.

[0015] The aerosol generator, wherein, at least one limiting buckle protrudes from the inner wall of one end of the sleeve shell far away from the opening end, at least one limiting groove extending along the circumferential direction is provided on the outer periphery of the inner shell, and the limiting buckle is accommodated in the limiting groove and can move along the extending direction of the limiting groove.

[0016] The aerosol generator, wherein, at least one arc-shaped dot is provided on the outer periphery of the inner shell, and the inner shell contacts the inner wall of the sleeve shell through the dot.

[0017] The aerosol generator further includes a housing having an avoidance hole, the housing covers the sleeve shell and is fixedly connected to the sleeve shell. When the housing is rotated by force, it drives the sleeve shell to rotate and opens the dust-proof cover so that the opening end is exposed in the avoidance hole. When the housing is rotated by force, it drives the sleeve shell to rotate and closes the dust-proof cover so that the dust-proof cover is exposed in the avoidance hole.

[0018] Beneficial effects: The present invention provides an aerosol generator, including an inner shell, a dust-proof cover and a sleeve shell. The inner shell is provided with a filler groove for placing the material to be aspirated. The two ends of the dust-proof cover are respectively rotatably connected to the two sides opposite to the opening end of the filler groove to be erected on the opening end. The sleeve shell is rotatably sleeved on the outer periphery of the inner shell. Gears are respectively provided at the two ends of the dust-proof cover, and a matching rack is provided on the end face of the sleeve shell close to the opening end. When the sleeve shell is rotated by an external force, the rack rotates and meshes with the gear, and the gear drives the dust-proof cover to rotate relative to the opening end to open or close the opening end. Through the meshing transmission of the gear and the rack, the opening and closing of the dust-proof cover are realized, which is not only stable in rotation but also easy to operate.

[0036] The present invention provides an aerosol generator, which includes an inner shell 1, a dust-proof cover 3, and a sleeve shell 2. The inner shell 1 is provided with a filling groove 11 for placing the material to be sucked. Both ends of the dust-proof cover 3 are rotatably connected to the two sides opposite to the opening end 111 of the filling groove 11 so as to be erected on the opening end 111. The sleeve shell 2 is rotatably sleeved on the outer periphery of the inner shell 1. Both ends of the dust-proof cover 3 are respectively provided with gears 32, and the end surface of the sleeve shell 2 close to the opening end 111 is provided with a matching rack 21. When the sleeve shell 2 is rotated by an external force, the rack 21 rotates and meshes with the gear 32, and the rack 21 drives the dust-proof cover 3 to rotate relative to the opening end 111 to open or close the opening end 111. In this embodiment, through the meshing transmission of the gear 32 and the rack 21, the opening and closing of the dust-proof cover 3 are realized, which is not only stable in rotation but also easy to operate.

[0037] In this embodiment, a heating component is provided inside the inner shell 1. The heating method of the heating component can be central heating, peripheral heating, infrared heating, electromagnetic heating, or air heating. The material to be sucked is placed in the filling groove 11 and is heated at a low temperature by the heating component to generate aerosol. The material to be sucked can be solid e-liquid, tobacco particles, naturally arranged tobacco shreds, or orderly arranged tobacco shreds, etc. Preferably, the material to be sucked is made into a cylindrical structure. Correspondingly, the size and shape of the filling groove 11 are adapted to the material to be sucked.

[0038] The dust-proof cover 3 includes a first cover body 301 and a second cover body 302. The first cover body 301 and the second cover body 302 have the same structure and both include a body 31, a gear 32, and a runner 33. Since the material to be sucked adopts a cylindrical structure, the filling groove 11 is a matching cylindrical groove, and its opening end 111 is also circular. Correspondingly, the body 31 is in the shape of an arc-shaped plate adapted to the opening end 111. When the bodies 31 of the first cover body 301 and the second cover body 302 are attached, the two form a hemispherical structure adapted to the opening end 111 to completely cover the opening end 111 and play a protective role.

[0039] Furthermore, the gear 32 is connected to one end of the body 31, and the runner 33 is connected to the other end of the body 31 opposite thereto. On opposite sides of the outer periphery of the inner shell 1, a first rotating shaft 17 and a second rotating shaft (not shown in the figure) protrude outward respectively. The gear 32 and the runner 33 are provided with through holes adapted to the first rotating shaft 17 and the second rotating shaft. Through the through holes, the gear 32 is rotatably sleeved on the first rotating shaft 17, and the runner 33 is rotatably sleeved on the second rotating shaft. Alternatively, the gear 32 is rotatably sleeved on the second rotating shaft, and the runner 33 is rotatably sleeved on the first rotating shaft 17. Thus, the body 31 is rotatably mounted on the open end 111. When the gear 32 meshes with the corresponding rack 21, it drives the gear 32 to rotate, so that the body 31 rotates around the first rotating shaft 17 and the second rotating shaft. Preferably, the first rotating shaft 17 and the second rotating shaft are concentrically arranged, so that the gear 32 and the rack 21 can rotate coaxially, ensuring the stability of the rotation of the body 31.

[0040] Furthermore, several first gear teeth 321 are provided at one end of the gear 32 away from the body 31. The sleeve 2 is rotatably sleeved on the outer periphery of the inner part, and the end face close to the open end 111 contacts the gear 32 and is provided with several second gear teeth adapted to the first gear teeth 321 to form an arc-shaped rack 21 structure. When the sleeve 2 is rotated by an external force, the second gear teeth mesh with the first gear teeth 321 for transmission, so that the gear 32 rotates around the first rotating shaft 17, thereby driving the runner 33 to rotate around the second rotating shaft, and finally driving the body 31 to rotate relative to the opening to open or close the open end 111. In this embodiment, the opening and closing of the dust cover 3 are realized through the meshing transmission of the gear 32. It is not only convenient to operate, but also the gear teeth can play a positioning role during the meshing process, making the rotation more accurate and stable. On the other hand, by applying a force to the sleeve to rotate it around its central axis, the opening and closing of the dust cover are controlled, and there is almost no impact on the overall appearance of the device during the opening and closing process of the dust cover, which is easy to control.

[0041] Preferably, the gears 32 of the first cover body 301 and the second cover body 302 are respectively located on opposite sides of the open end 111. That is, the first gear teeth 321 on the first cover body 301 and the first gear teeth 321 on the second cover body 302 are respectively located on both sides of the open end 111. Correspondingly, the sleeve 2 is correspondingly provided with two arc-shaped racks 21 distributed on both sides of the open end 111. When the sleeve 2 is rotated by an external force, the two racks 21 rotate and mesh with the corresponding gears 32 for transmission, so that the two gears 32 rotate in opposite directions and drive the two bodies 31 to separate from each other to open the open end 111 or fit together to close the open end 111.

[0042] Specifically, in this embodiment, the gear 32 of the first cover 301 is sleeved on the first rotating shaft 17, and the runner 33 of the first cover 301 is sleeved on the second rotating shaft. At the same time, the gear 32 of the second cover 302 is sleeved on the second rotating shaft, and the runner 33 of the second cover 302 is sleeved on the first rotating shaft 17. Taking this as an example, when the gear 32 of the first cover 301 applies a clockwise rotating force to the sleeve 2, the two racks 21 move clockwise around the center of the sleeve 2 driven by the sleeve 2 and engage with the corresponding gears 32. Thereby, the gear 32 of the first cover 301 rotates clockwise around the first rotating shaft 17, and the runner 33 of the first cover 301 rotates clockwise around the second rotating shaft. Since the gear 32 of the first cover 301 and the gear 32 of the second cover 302 are respectively located on opposite sides of the open end 111, that is, they are centrosymmetric. Therefore, when viewed from the direction facing the gear 32 of the first cover 301, the gear 32 of the second cover 302 rotates counterclockwise around the second rotating shaft, and the runner 33 of the second cover 302 rotates counterclockwise around the first rotating shaft 17. Thereby, the bodies 31 of the first cover 301 and the second cover 302 are respectively driven to rotate in opposite directions and move away from each other. Finally, the open end 111 is completely exposed in the space formed between the two bodies 31 to completely open the open end 111 and realize the opening process of the dust cover 3. Similarly, when the gear 32 of the first cover 301 applies a counterclockwise rotating force to the sleeve 2, the two racks 21 move counterclockwise around the center of the sleeve 2 driven by the sleeve 2 and engage with the corresponding gears 32. Thereby, the gear 32 and the runner 33 of the first cover 301 rotate counterclockwise, and the gear 32 and the runner 33 of the second cover 302 rotate clockwise, and finally drive the two bodies 31 to approach each other until they are completely attached to form a closed hemispherical structure that completely covers the open end 111, realizing the closing process of the dust cover 3. In this embodiment, the opening and closing of the dust cover 3 are realized by the reverse rotation of the two bodies 31, reducing the rotation stroke of the two bodies 31 and making the rotation operation simpler and more controllable.

[0043] Furthermore, in order to prevent the two bodies 31 from colliding and being damaged during the process of approaching each other, a first slot 311 is provided on the side of the body 31 of the first cover 301 facing the body 31 of the second cover 302, and a second slot 312 is provided on the side of the body 31 of the second cover 302 facing the body 31 of the first cover 301. A limiting post 12 protrudes outward from the side of the open end 111. When the two bodies 31 rotate to fit together, the first slot 311 and the second slot 312 respectively abut against both sides of the limiting post 12 to limit the rotation positions of the two bodies 31 through the limiting post 12.

[0044] The limiting post 12 can be one or two. Preferably, there are two limiting posts 12, which are respectively located directly above the first rotating shaft 17 and the second rotating shaft to achieve centered setting, so that the two bodies 31 receive balanced acting forces from the limiting posts 12 during rotation. Preferably, when the two bodies 31 are completely fitted, the first slot 311 and the second slot 312 respectively cover both sides of the limiting post 12 to enclose a limiting hole adapted to the limiting post 12, thereby maximizing the contact area between the two slots and the limiting post 12, preventing the acting force between the slot and the limiting post 12 from being too concentrated, and at the same time facilitating the complete closing of the dust cover 3 and avoiding gaps between the two bodies 31.

[0045] In this embodiment, the aerosol generator further includes an elastic damping member 4. The elastic damping member 4 has an annular structure and includes an elastic member 42 and a pressure ring 41 that are sequentially sleeved on the inner shell 1 along the direction close to the opening end 111. The elastic member 42 can be a spring. At least two adjacent flanges 411 are provided at one end of the pressure ring 41 facing away from the elastic member 42. The housing 2 is pressed against the end of the pressure ring 41 provided with the flanges 411 so that the pressure ring 41 pre-presses the elastic member 42, thereby elastically abutting against the elastic member 42. Preferably, a first limiting ring 16 protrudes from the outer periphery of the inner shell 1, and a second limiting ring 24 protrudes from the inner wall of the housing 2. There is a distance between the first limiting ring 16 and the second limiting ring 24 in the axial direction to enclose an annular limiting groove 6, and the elastic damping member 4 is accommodated in the annular limiting groove 6. That is, the second limiting ring 24 presses against the pressure ring 41 so that the pressure ring 41 pre-presses the elastic member 42, so that one end of the elastic member 42 elastically abuts against the first limiting ring 16 and the other end elastically abuts against the pressure ring 41. The elastic damping member 4 is limited in the axial direction by the annular limiting groove 6, and at the same time, the elastic damping member 4 is facilitated to be installed and positioned by respectively providing limiting rings on the housing 2 and the inner shell 1.

[0046] Furthermore, the housing 2 is provided with a protrusion 22 adapted to the flange 411 facing the pressure ring 41, that is, the second limiting ring 24 is provided with the protrusion 22. The protrusion 22 is located within any one of the flanges 411. When the housing 2 is forced to rotate, the protrusion 22 is driven to rotate and slide into another flange 411. During this process, the pressure ring 41 moves downward along the axial direction of the inner shell 1 under the action of the protrusion 22 and further compresses the elastic member 42. In turn, the elastic member 42 generates a resilience force acting on the pressure ring 41 and is transmitted to the housing 2, thereby increasing the resistance to the rotation of the housing 2, buffering the instantaneous impact force and providing a damping feel.

[0047] Preferably, the flange 411 is a smooth arc-shaped flange 411, and the protrusion 22 is a smooth arc-shaped protrusion 22. In this way, during the process of the protrusion 22 sliding from one flange 411 to its adjacent flange 411, the contact is smooth, which is beneficial to reducing the resistance of the protrusion 22 during sliding and making the sliding smoother. In practical applications, one protrusion 22 corresponds to at least two adjacent flanges 411 to form a set of sliding combinations. The sliding combinations can be one, two, or more. Preferably, the sliding combinations are two, and the two sliding combinations are symmetrically distributed about the center of the inner shell 1. That is, the protrusions 22 are respectively provided on both sides of the sleeve 2, and the connection line of the two protrusions 22 intersects the central axis of the inner shell 1. Correspondingly, the pressing ring 41 is symmetrically distributed with two sets of flanges 411. In this way, the two symmetric sides of the sleeve 2 are respectively subjected to the same rotational resistance, thereby achieving balanced force.

[0048] Preferably, at least one slide rail 13 extending in the axial direction is convexly provided on the outer periphery of the inner shell 1, and a matching chute 412 is provided on the inner side wall of the pressing ring 41. When the pressing ring 41 is sleeved on the outer periphery of the inner shell 1, the slide rail 13 is accommodated in the corresponding chute 412. Thus, through the cooperation between the chute 412 and the slide rail 13, the pressing ring 41 can only slide along the axial direction of the inner shell 1, and will not rotate along the outer periphery of the inner shell 1 and generate radial displacement.

[0049] Furthermore, at least one limiting buckle 23 is convexly provided on the inner side wall of the end of the sleeve 2 far away from the opening end 111, and the limiting buckle 23 extends along the circumferential direction of the sleeve 2. Correspondingly, a limiting groove 14 extending along the circumferential direction is provided at the corresponding position on the outer periphery of the inner shell 1. The limiting buckle 23 is accommodated in the limiting groove 14. When the sleeve shell 2 rotates, the limiting hole moves along the extending direction of the limiting groove 14. Preferably, the thickness of the limiting buckle 23 in the axial direction of the sleeve 2 is equal to or slightly smaller than the width of the limiting groove 14 in the axial direction of the sleeve 2. In this way, the buckle can only move along the extending direction of the limiting groove 14, and cannot move along the axial direction of the sleeve 2, so that the sleeve 2 can only rotate relative to the inner shell 1 without generating axial displacement.

[0050] In this embodiment, at least one arc-shaped wave point 15 is provided on the outer periphery of the inner shell 1, and the outer periphery of the inner shell 1 contacts the inner wall of the sleeve 2 through the at least one wave point 15. When the sleeve 2 rotates, the inner wall of the sleeve 2 forms smooth electrical contact with at least one of the wave points 15, reducing the contact area between the two, thereby reducing the rotational resistance and making the rotation smoother.

[0051] In this embodiment, the aerosol generator further includes a housing 5. The housing 5 has a hollow structure, with an opening at one end and an avoidance hole 51 at the other end. The housing 5 is fastened and covered on the outer periphery of the sleeve 2 from the opening, and the dust-proof cover 3 or the filling groove 11 is exposed from the avoidance hole 51. In practical applications, a clamping groove (not shown in the figure) is provided on the inner side wall of the housing 5, and a matching buckle (not marked in the figure) is provided on the outer periphery of the sleeve 2. The housing 5 and the sleeve 2 are firmly connected through the cooperation between the clamping groove and the buckle. When the inner and outer housing 5 is rotated, the housing 5 drives the sleeve 2 to rotate relative to the inner housing 1, and the gear 32 meshes with the rack 21 to open or close the dust-proof cover 3. When the dust-proof cover 3 opens the opening end 111, the opening end 111 is exposed from the avoidance hole 51. At this time, the user can sequentially pass through the avoidance hole 51 and the opening end 111 and add the drawable material into the filling groove 11. When the dust-proof cover 3 closes the opening end 111, the dust-proof cover 3 is exposed from the avoidance hole 51. In this embodiment, the dust-proof cover 3 is covered by the housing 5, so that only a part of the dust-proof cover 3 is exposed in the avoidance hole 51, which not only maintains the beauty and integrity of the device appearance, but also is convenient to operate and can prevent the dust-proof cover 3 from being accidentally touched. On the other hand, by rotating the housing 5, the way of rotating the housing around its own central axis hardly changes the overall appearance and structure of the device, and it is easy to control the rotation stroke, making the operations of opening and closing the dust-proof cover 3 easy to control.

[0052] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
