Description

Technical Field

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

[0002] The existing aerosol generator is provided with a stuffing groove for inserting a drawable material. However, when the user takes out the drawable material, the open end of the stuffing groove is in an open state and is always exposed. This causes the aerosol in the device to dissipate from the open end, and at the same time, dust or pollutants from the outside can also enter the stuffing groove through the open end, resulting in contamination of the device. In order to prevent dust or pollutants from entering the stuffing groove through the opening, a silica gel plug or a dust-proof cover is usually provided in the device. However, although the silica gel plug is easy to operate, it is easy to lose; on the other hand, the existing dust-proof 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 dust-proof 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 dust-proof cover.

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

[0006] An aerosol generator, comprising an inner shell, a sleeve shell, and a dust-proof cover. The inner shell is provided with a stuffing groove for accommodating a drawable material. Both ends of the dust-proof cover are rotatably connected to opposite sides of the open end of the stuffing groove so as to be mounted on the open end. At least one first gear tooth is provided at both ends of the dust-proof cover. The sleeve shell is rotatably sleeved on the outer periphery of the inner shell, and at least one second gear tooth adapted to the at least one first gear tooth is provided. When the sleeve shell is forced to rotate relative to the inner shell, the second gear tooth is driven to mesh with the first gear tooth, so that the dust-proof cover rotates relative to the inner shell and opens or closes the open end.

[0007] In the aerosol generator, the dust-proof 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 first rotating part and a second rotating part respectively connected to both ends of the main body. The first rotating part and the second rotating part are coaxially rotatably connected to both sides of the open end so that the main body is mounted on the open end. At least one of the first rotating parts is provided with the first gear tooth; when the first gear tooth meshes with the second gear tooth, the first rotating part drives the corresponding second rotating part 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 a first rotating part of the first cover body and a first rotating part of the second cover body are respectively located on two sides of the open end, and the sleeve correspondingly is provided with second gear teeth distributed on two sides of the open end. When the sleeve rotates under an external force, the second gear teeth rotate and mesh with corresponding first gear teeth for transmission, so that the two first rotating parts 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, and when the body of the first cover body fits with the body of the second cover body, a spherical structure adapted to the open end is formed to close the open end.

When the two bodies fit together, the first slot and the second slot respectively abut against two sides of the limiting post.

[0011] The aerosol generator further includes an elastic member provided with a slideway. The elastic member is fastened to a side of the body facing the open end, and the slideway extends along a rotation direction of the body. Correspondingly, the open end is provided with a clamping post adapted to the slideway. The clamping post extends into the slideway and can slide along the slideway.

[0012] The aerosol generator, wherein a width of at least a partial area of the slideway is smaller than an outer diameter of the clamping post. When the clamping post slides to the partial area, the clamping post elastically abuts against the slideway.

[0013] The aerosol generator, wherein the elastic member includes a U-shaped body, and a first fixing part and a second fixing part formed by bending away from two sides of an opening of the U-shaped body. The U-shaped body extends from the opening to a closed end to form the slideway.

[0014] The aerosol generator, wherein the body is provided with a mounting groove adapted to the elastic member, and the mounting groove is respectively provided with buckling parts corresponding to the closed end, the first fixing part and the second fixing part of the U-shaped body to fasten the elastic member.

[0015] The aerosol generator, wherein a side wall of the sleeve is provided with a guiding groove extending along a rotation direction, an outer periphery of the inner shell is provided with a matching guiding block, and the guiding block is received in the guiding groove. When the sleeve rotates under force, it drives the guiding groove to move relative to the guiding block until the guiding block abuts against an end wall of the guiding 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 outer shell through the dots.

[0017] The aerosol generator further includes an outer shell having an avoidance hole. The outer shell covers the outer shell and is fixedly connected to the outer shell. When the outer shell drives the outer shell to rotate to open the opening end of the dust cover, the opening end is exposed from the avoidance hole; when the outer shell drives the outer shell to rotate to close the opening end of the dust cover, the dust cover is exposed from the avoidance hole.

[0018] Beneficial effects: The present invention provides an aerosol generator, including an inner shell, an outer shell, and a dust cover. The inner shell is provided with a filler groove for accommodating the drawable material. The two ends of the dust cover are respectively rotatably connected to the two sides opposite to the opening end of the filler groove to be mounted on the opening end, and at least one first gear tooth is respectively provided at the two ends of the dust cover. The outer shell is rotatably sleeved on the outer periphery of the inner shell, and at least one second gear tooth adapted to the at least one first gear tooth is provided. When the outer shell is forced to rotate relative to the inner shell, the second gear tooth is driven to mesh with the first gear tooth, so that the dust cover rotates relative to the inner shell and opens or closes the opening end. By providing a dust cover to shield and protect the opening end of the filler groove, and at the same time adopting the method of gear meshing transmission to realize the opening and closing of the dust cover, the operation is convenient and reliable.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Please refer to Figures 1-9 , which is a schematic diagram of a preferred embodiment of the aerosol generator of the present invention. The aerosol generator includes an inner shell 1, a sleeve shell 2, and a dust-proof cover 3. The inner shell 1 is provided with a filler groove 11 for accommodating the drawable material. Among them, the drawable material can be solid e-liquid, tobacco particles, naturally arranged tobacco shreds, or orderly arranged tobacco shreds, etc. After the drawable material is placed in the filler groove 11, it is heated by a heating component arranged inside the aerosol generator to generate aerosol. Both ends of the dust-proof cover 3 are rotatably connected to the two sides opposite to the opening end 111 of the filler groove 11 to be erected on the opening end 111, and at least one first gear tooth 321 is provided at both ends of the dust-proof cover 3. The sleeve shell 2 is rotatably sleeved on the outer periphery of the inner shell 1, and at least one second gear tooth 21 adapted to the at least one first gear tooth 321 is provided. When the sleeve shell 2 is forced to rotate relative to the inner shell 1, it drives the second gear tooth 21 to mesh with the first gear tooth 321 for transmission, so that the dust-proof cover 3 rotates relative to the inner shell 1 and opens or closes the opening end 111. In this embodiment, by providing the dust-proof cover 3 to shield and protect the opening end 111 of the filler groove 11, and at the same time adopting the method of gear meshing transmission to realize the opening and closing of the dust-proof cover 3, the operation is convenient and reliable.

[0037] In this embodiment, a heating component is provided inside the inner shell 1, and the heating method of the heating component can be central heating, peripheral heating, infrared heating, electromagnetic heating, or air heating. The drawable material placed in the filler groove 11 is heated at a low temperature by the heating component to generate aerosol. Preferably, the drawable material is made into a cylindrical structure, and correspondingly, the size and shape of the filler groove 11 are adapted to the drawable material. As Figure 3As shown, the dust 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 first rotating part 32, and a second rotating part 33. Since the suctionable material has a cylindrical structure, the stuffing groove 11 is a matching cylindrical groove, and its open end 111 is also circular. Correspondingly, the body 31 has an arc-shaped plate structure adapted to the open end 111. When the bodies 31 of the first cover body 301 and the second cover body 302 are attached, the two bodies 31 form a hemispherical structure adapted to the open end 111 to completely cover the open end 111 and play a protective role.

[0038] Further, as Figure 2 , Figure 4 and Figures 6-9 shown, the first rotating part 32 is connected to one end of the body 31, and the second rotating part 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 16 and a second rotating shaft (not shown in the figure) symmetrically protrude outward respectively. The first rotating part 32 is rotatably sleeved on the first rotating shaft 16, and the second rotating part 33 is rotatably sleeved on the second rotating shaft. Or the first rotating part 32 is rotatably sleeved on the second rotating shaft, and the second rotating part 33 is rotatably sleeved on the first rotating shaft 16. Thus, the body 31 is rotatably mounted on the open end 111. Preferably, both the first rotating part 32 and the second rotating part 33 are circular, and the rotating shafts respectively pass through the centers of the corresponding rotating parts to achieve rotation.

[0039] Further, at least one first gear tooth 321 is provided at one end of the first rotating part 32 away from the body 31 to form a gear structure. The sleeve 2 is rotatably sleeved on the outer periphery of the inner shell 1, and the end face close to the open end 111 contacts the first rotating part 32 and the second rotating part 33, and is provided with at least one second gear tooth 21 adapted to the first gear tooth 321 to form an arc-shaped rack structure. When the sleeve 2 is rotated by an external force, the second gear tooth 21 meshes with the first gear tooth 321 for transmission, so that the first rotating part 32 rotates around the first rotating shaft 16, thereby driving the second rotating part 33 to rotate around the second rotating shaft, and finally driving the body 31 to rotate relative to the open end 111 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 gears, which is not only convenient to operate, but also the gear teeth can play a positioning role during the meshing process, making the rotation more precise and stable. On the other hand, by applying force to the sleeve to rotate it around its central axis to control the opening and closing of the dust cover, there is almost no impact on the overall appearance of the device during the opening and closing process of the dust cover, and it is easy to control.

[0040] Preferably, the first rotating parts 32 of the first cover body 301 and the first rotating parts 32 of the second cover body 302 are respectively located on opposite sides of the opening 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 opening end 111. Correspondingly, the sleeve 2 is correspondingly provided with second gear teeth 21 distributed on both sides of the opening end 111. When the sleeve 2 is rotated by an external force, the second gear teeth 21 rotate and mesh with the corresponding first gear teeth 321 to drive the two first rotating parts 32 to rotate in opposite directions, and drive the two bodies 31 to separate from each other to open the opening end 111, or to fit together to close the opening end 111.

[0041] Specifically, as Figures 6-9As shown in the figure. In this embodiment, the first rotating part 32 of the first cover body 301 is sleeved on the first rotating shaft 16, the second rotating part 33 of the first cover body 302 is sleeved on the second rotating shaft, and at the same time, the first rotating part 32 of the second cover body is sleeved on the second rotating shaft, and the second rotating part of the second cover body 302 is sleeved on the first rotating shaft 16 as an example for illustration. When a clockwise rotating force is applied to the housing 2 by facing the first rotating part 32 of the first cover body 301, the second gear teeth 21 move clockwise around the center of the housing 2 driven by the housing 2 and mesh with the corresponding first gear teeth 321. Thereby, the first rotating part 32 of the first cover body 301 rotates clockwise around the first rotating shaft 16, and the second rotating part 33 of the first cover body 301 rotates clockwise around the second rotating shaft. Since the first rotating part 32 of the first cover body 301 and the first rotating part 32 of the second cover body 302 are located on opposite sides, that is, they are centrosymmetric. Therefore, from the direction facing the first rotating part 32 of the first cover body 301, the first rotating part 32 of the second cover body 302 rotates counterclockwise around the second rotating shaft 16, and the second rotating part 33 of the second cover body 302 rotates counterclockwise around the first rotating shaft. Thereby, the main bodies 31 of the first cover body 301 and the second cover body 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 main bodies 31 to completely open the open end 111 and realize the opening process of the dust cover 3. Similarly, when a counterclockwise rotating force is applied to the housing 2 by facing the first rotating part 32 of the first cover body 301, the second gear teeth 21 move counterclockwise around the center of the housing 2 driven by the housing 2 and mesh with the corresponding first gear teeth 321. Thereby, the first rotating part 32 and the second rotating part 33 of the first cover body 301 rotate counterclockwise, and the first rotating part 32 and the second rotating part 33 of the second cover body 302 rotate clockwise, and finally drive the two main 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 main bodies 31, reducing the rotation stroke of the two main bodies 31 and making the rotation operation simpler and more controllable.

[0042] Furthermore, in order to prevent the two main bodies 31 from colliding and being damaged during the process of approaching each other, a first slot 313 is provided on the side of the main body 31 of the first cover body 301 facing the main body 31 of the second cover body 302, and a second slot 314 is provided on the side of the main body 31 of the second cover body 302 facing the main body 31 of the first cover body 301. A limiting post 12 protrudes outward from the side of the open end 111. When the two main bodies 31 rotate to fit together, the first slot 313 and the second slot 314 respectively abut against both sides of the limiting post 12 to limit the rotation positions of the two main bodies 31 through the limiting post 12.

[0043] The limiting posts 12 may be one or two. Preferably, there are two limiting posts 12, which are respectively located directly above the first rotating shaft 16 and the second rotating shaft to achieve centering arrangement, so that the two bodies 31 are subjected to balanced acting forces from the limiting posts 12 during rotation. Preferably, when the two bodies 31 are completely fitted, the first slotted groove 313 and the second slotted groove 314 respectively cover both sides of the limiting post 12 to enclose a limiting hole adapted to the limiting post 12, so as to maximize the contact area between the two slotted grooves and the limiting post 12, prevent the acting force between the slotted groove and the limiting post 12 from being too concentrated, and at the same time facilitate the complete closing of the dust cover 3 and avoid gaps between the two bodies 31.

[0044] Preferably, as Figure 2 and Figure 5 shown, the aerosol generator further includes an elastic member 4, which is fastened to one side of the body 31 facing the opening end 111. The elastic member 4 is provided with a slideway 411 extending along the rotation direction of the body 31. Correspondingly, the opening end 111 is provided with a clamping post 13 adapted to the slideway 411 facing the body 31, and the clamping post 13 extends into the slideway 411. When the body 31 rotates, it drives the slideway 411 to rotate, so that the clamping post 13 moves along the slideway 411. In this embodiment, the cooperation between the clamping post 13 and the slideway 411 is used to guide the rotation of the body 31 to make its rotation smoother.

[0045] Furthermore, as Figure 7 and Figure 9 shown, the width of at least part of the slideway 411 is smaller than the outer diameter of the clamping post 13. When the clamping post 13 moves relative to the slideway 411 to this part of the area, the clamping post 13 is elastically clamped in this area. That is to say, when the clamping post 13 slides through this part of the area, it needs to overcome the acting force between it and the slideway 411, thereby increasing the resistance of the body 31 to rotate, and further enhancing the sense of rotational damping.

[0046] In this embodiment, the elastic member 4 includes a U-shaped body 41, a first fixing portion 42, and a second fixing portion 43. The U-shaped body 41 extends from the opening to the closed end to form the slideway 411. When the body 31 rotates, the clamping post 13 slides from the opening to the closed end or from the closed end to the opening. Preferably, the opening of the U-shaped body 41 faces the center of the inner shell 1, that is, the opening is closer to the center of the inner shell 1 and is located at the proximal end, and the closed end is farther from the center of the inner shell 1 and is located at the distal end. When the two bodies 31 rotate to separate from each other to completely open the opening end 111 of the stuffing box 11, the clamping post 13 slides along the slideway 411 to abut against the closed end. The body 31 is limited by the closed end to prevent the dust cover 3 from colliding with the sleeve 2 during the opening process.

[0047] The first fixing portion 42 is formed by bending outward from one side of the opening of the U-shaped body 41, and the second fixing portion 43 is formed by bending outward from the other side of the opening of the U-shaped body 31. The U-shaped body 41, the first fixing portion 42, and the second fixing portion 43 form a C-shaped structure. The body 31 is provided with a mounting groove 311 adapted to the elastic member 4. The body 31 is embedded in the mounting groove 311 and fits with the side of the body 31 facing the opening end 111. The mounting groove 311 is respectively provided with buckling portions 312 corresponding to the closed end, the first fixing portion 42, and the second fixing portion 43 of the U-shaped body 41 to fasten the elastic member 4 to the body 31 in a triangular fixing manner, improving the installation stability.

[0048] In this embodiment, the side wall of the sleeve 2 is provided with a guiding groove 22 extending along the rotation direction, and a matching guiding block 14 is convexly provided on the outer periphery of the inner shell 1. The guiding block 14 is received in the guiding groove 22. When the sleeve 2 is forced to rotate, the guiding groove 22 is driven to move relative to the guiding block 14 until the guiding block 14 abuts against the end wall of the guiding groove 22. The rotation of the sleeve 2 is guided and limited through the cooperation between the guiding block 14 and the guiding groove 22, making its rotation smoother and more stable. In practical applications, the guiding groove 22 can be arranged at any position on the side wall of the sleeve 2. For example, it can be arranged on the upper end face or the lower end face of the side wall, the middle part, the upper part or the lower part of the side wall, etc.

[0049] Preferably, as Figure 3 shown, at least one arc-shaped dot 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 dot 15. When the sleeve 2 rotates, the inner wall of the sleeve 2 forms a smooth point contact with at least one dot 15, reducing the contact area between the two, thereby reducing the rotation resistance and making the rotation smoother.

[0050] In this embodiment, as Figures 1-3 shown, 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 covers the outer periphery of the sleeve 2 from the opening, and the dust cover 3 is exposed from the avoidance hole 51. A clamping groove is provided on the inner side wall of the housing 5, and a matching clamping buckle is provided on the outer periphery of the sleeve 2. The housing 5 and the sleeve 2 are tightly connected through the cooperation between the clamping buckle and the clamping groove. When the housing 5 is rotated, the housing 5 drives the sleeve 2 to rotate relative to the inner housing 1, and the first gear teeth 321 cooperate with the second gear teeth 21 to open or close the dust cover 3. When the dust 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 to add the drawable material into the filling slot 11. When the dust cover 3 closes the opening end 111, the dust cover 3 is exposed from the avoidance hole 51. In this embodiment, the dust cover 3 is covered by the housing 5, so that the dust cover 3 is only partially 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 cover 3 from being misoperated. 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 operation of opening and closing the dust cover 3 easy to control.

[0051] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present invention.
