Description

Technical Field

[0001] This utility model relates to the field of aroma diffuser technology, and in particular to an aroma diffuser using a single-twist quick-release structure. Background Technology

[0002] Aroma diffusers, as a popular air freshener and atmosphere-creating device, typically consist of a main unit (containing core components such as an air pump and control circuitry) and an essential oil storage container. To facilitate easy addition and replacement of essential oils, the storage container is generally designed to be detachably mounted on the main unit.

[0003] In existing technologies, the detachable installation and fixing of essential oil storage containers mainly relies on two common methods: threaded connection and snap-fit ​​fixing. Threaded connection fixing involves rotating the storage component to engage the threads on its outer wall with the threads on the inner wall of the main body to achieve connection and locking. Snap-fit ​​fixing typically uses protruding snap-fit ​​structures (such as hooks or points) on the storage component or main body, with corresponding grooves or slots. Pressing or pushing deforms the snap-fit ​​and locks it into a predetermined position for fixing. However, these fixing methods generally suffer from inconvenience in disassembly and assembly, and may lead to component damage or poor sealing due to improper operation, thus affecting the overall performance and lifespan of the equipment.

[0004] Therefore, there is an urgent need for a simpler, more efficient, and more reliable solution for assembling and disassembling essential oil storage containers to address the aforementioned shortcomings in existing technologies. Utility Model Content

Each guide groove has an inclined first guide surface. The upper guide has multiple positioning grooves that mate with the guide grooves. Each positioning groove has an inclined second guide surface. The side wall of the rotating component has a limiting shaft. One end of the rotating component passes through the mounting hole and the irregular hole, and the other end passes through the upper guide and extends into the lower guide. When the limiting shaft is located within the positioning groove, the first limiting plate is engaged with the bottom of the essential oil bottle or aligned with the irregular hole. The first elastic member is disposed within the second mounting groove.

[0015] Optionally, the lower guide member has a second limiting post protruding from one end within the fixing groove, and the inner wall of the mounting hole has a third limiting groove corresponding to the second limiting post.

[0016] Optionally, a limiting seat is provided on the side of the upper guide member away from the lower guide member, and the limiting seat is located in the mounting hole.

[0017] Optionally, the diffuser body further includes an air pump assembly, which is disposed within the first housing;

[0018] The essential oil bottle includes a second housing, an atomizing component, and a second limiting plate. The atomizing component is disposed inside the second housing and communicates with the air pump component. The bottom of the second housing is recessed to form a relief groove. The second limiting plate is fixed in the relief groove. The irregular hole is opened on the second limiting plate.

[0019] Optionally, the air pump assembly includes an air pump, a conduit, and an air guide rod. The air pump is detachably installed in the first housing. One end of the conduit is connected to the air pump, and the other end is connected to the air guide rod.

[0020] The lower guide member, the upper guide member, the rotating member, and the second housing are provided with through holes, and the air guide rod passes through the through holes and communicates with the atomizing component.

[0022] This utility model provides a diffuser with a single-twist quick-installation structure, employing the following technical solution: A first mounting groove and mounting holes are provided on the diffuser body, and a shaped hole corresponding to the mounting hole is provided on the bottom of the essential oil bottle; a pressing mechanism is provided on the diffuser body, including a guide component, a first elastic element, and a rotating component. One end of the rotating component has a first limiting plate, and the other end is rotatably connected to the guide component, with elasticity provided by the first elastic element. When the essential oil bottle is installed in the first mounting groove, pressing the essential oil bottle presses the rotating component downwards, forcing it to rotate under the action of the guide component, thereby locking or unlocking the first limiting plate by engaging it with the bottom of the essential oil bottle or aligning it with the shaped hole.

[0023] This technical solution links rotational motion with pressing action, using the rotation of the rotating component to automatically lock and release the limiting snap-fit ​​structure. This avoids the inconvenience of multiple rotations required by traditional threaded connections and also avoids the fatigue fracture problem of snap-fit ​​structures under frequent disassembly and assembly. Simultaneously, with the cooperation of the guide component and the elastic component, the rotating component can stably and reliably position the limiting plate, ensuring a firm connection and good sealing during use of the essential oil bottle.

[0024] Therefore, this technical solution not only improves the ease of assembling and disassembling the essential oil bottle, but also effectively enhances the reliability and service life of the structure. It significantly improves the problems of cumbersome operation, easily damaged buckles, and poor sealing in the existing technology, thereby effectively improving the practicality of the diffuser.

[0039] This utility model proposes a diffuser that uses a single-twist quick-release structure.

[0040] In the embodiments of this utility model, such as Figures 1 to 7 As shown, the diffuser with a single-twist quick-release structure includes:

[0041] The diffuser body 10 is provided with a first mounting groove 13, and the bottom wall of the first mounting groove 13 is provided with a mounting hole 14.

[0042] An essential oil bottle 20 is detachably installed in the first mounting groove 13, and the bottom of the essential oil bottle 20 is provided with an irregular hole 231 corresponding to the position of the mounting hole 14;

[0043] The pressing mechanism includes a guide component 30, a first elastic element 34, and a rotating element 33. The guide component 30 is fixed on the diffuser body 10 at the position corresponding to the mounting hole 14. One end of the rotating element 33 is provided with a first limiting plate 331 adapted to the irregular hole 231, and the other end extends into the guide component 30 and is rotatably connected to the guide component 30. The first elastic element 34 is provided in the guide component 30, and one end of the first elastic element 34 abuts against the guide component 30, and the other end abuts against the rotating element 33.

[0044] When the essential oil bottle 20 is installed in the first mounting slot 13, pressing the essential oil bottle 20 causes the essential oil bottle 20 to squeeze the rotating member 33. The guide component 30 drives the rotating member 33 to rotate so that the first limiting plate 331 is engaged with the bottom of the essential oil bottle 20 or aligned with the irregular hole 231.

[0045] In this embodiment, there is a diffuser body 10, an essential oil bottle 20, and a pressing mechanism.

[0046] The diffuser body 10 is provided with a first mounting groove 13 for mounting an essential oil bottle 20. The bottom wall of the first mounting groove 13 is provided with a mounting hole 14 for the rotating part 33 to pass through and cooperate with the essential oil bottle 20.

[0047] The essential oil bottle 20 is detachably installed in the first mounting slot 13, allowing users to easily replace or add different essential oils as needed. The bottom of the essential oil bottle 20 is provided with an irregularly shaped hole 231, which corresponds to the mounting hole 14 of the diffuser body 10, and is used to engage or unlock with the first limiting plate 331 of the rotating component 33.

[0048] The pressing mechanism is used to reliably fix or release the essential oil bottle 20, and includes a guide assembly 30, a first elastic element 34, and a rotating element 33. The guide assembly 30 is disposed on the diffuser body 10 and corresponds to the mounting hole 14, serving to guide and constrain the rotation trajectory of the rotating element 33. One end of the rotating element 33 is provided with a first limiting plate 331, which is adapted to the irregular hole 231 to lock or release the essential oil bottle 20; the other end of the rotating element 33 extends into the guide assembly 30 and is rotatably connected to it, allowing it to change angle during pressing.

[0049] The first elastic member 34 is disposed inside the guide assembly 30, with one end abutting against the guide assembly 30 and the other end abutting against the rotating member 33, providing a rebound force so that the rotating member 33 maintains its initial position in the non-operating state.

[0050] In actual use, when the user inserts the essential oil bottle 20 into the first mounting slot 13 and presses it down, the bottom of the essential oil bottle 20 will contact and press down on the rotating part 33. Under the elastic force provided by the first elastic part 34, the rotating part 33 rotates along the path set by the guide assembly 30, so that the first limiting plate 331 is aligned or engaged with the irregular hole 231, thereby realizing the quick installation or removal of the essential oil bottle 20.

[0051] Through the above structural combination, this embodiment provides a compact and easy-to-operate single-twist quick-release structure. Users only need to press once to install or remove the essential oil bottle, avoiding the cumbersome operation and wear problems of traditional buckle or threaded connection, thus improving the practicality and user experience of the diffuser.

[0052] This utility model provides a diffuser with a single-twist quick-release structure, employing the following technical solution: A first mounting groove 13 and mounting holes 14 on the bottom wall of the diffuser body 10 are provided; the bottom of the essential oil bottle 20 has a shaped hole 231 corresponding to the mounting hole 14. A pressing mechanism is provided on the diffuser body 10, including a guide component 30, a first elastic element 34, and a rotating component 33. One end of the rotating component 33 has a first limiting plate 331, and the other end is rotatably connected to the guide component 30, with elasticity provided by the first elastic element 34. When the essential oil bottle 20 is installed into the first mounting groove 13, pressing the essential oil bottle 20 presses the rotating component 33 downwards, forcing it to rotate under the action of the guide component 30. This causes the first limiting plate 331 to engage with the bottom of the essential oil bottle 20 or align with the shaped hole 231, achieving locking or unlocking.

[0053] This technical solution links rotational motion with pressing action, utilizing the rotation of the rotating component 33 to automatically lock and release the limiting snap-fit ​​structure. This avoids the inconvenience of multiple rotations required by traditional threaded connections and also avoids the problem of fatigue fracture caused by frequent disassembly and assembly of snap-fit ​​structures. Simultaneously, with the cooperation of the guide component 30 and the first elastic component 34, the rotating component 33 can stably and reliably position the limiting plate 331, ensuring a firm connection and good sealing of the essential oil bottle 20 during use.

[0054] Therefore, this technical solution improves the ease of assembling and disassembling the essential oil bottle 20, effectively enhances the reliability and service life of the structure, and significantly improves the problems of cumbersome operation, easy damage to buckles, and poor sealing in the existing technology, thereby effectively improving the practicality of the diffuser.

[0055] Furthermore, such as Figures 1 to 5 As shown, the diffuser body 10 includes a first housing 11 and a mounting bracket 12. The first housing 11 has a mounting opening 111, and the mounting bracket 12 is fixed inside the first housing 11 corresponding to the mounting opening 111. A first mounting groove 13 is formed on the mounting bracket 12. The guide component 30 is located at the bottom of the mounting bracket 12. In this embodiment, the diffuser body 10 includes a first housing 11 and a mounting bracket 12. The first housing 11 has a mounting opening 111, which facilitates the user to insert or remove the essential oil bottle 20. The mounting bracket 12 is fixedly set inside the first housing 11 and corresponds to the mounting opening 111, providing stable support. The first mounting groove 13 is set on the mounting bracket 12 to accommodate the essential oil bottle 20. The guide component 30 is located at the bottom of the mounting bracket 12 and aligns with the mounting hole 14 at the lower end of the essential oil bottle 20, achieving precise cooperation between the rotating component 33 and the irregular hole 231, ensuring the reliability of fixing and unlocking.

[0056] Furthermore, such as Figures 1 to 4As shown, the guide assembly 30 includes an upper guide member 31 and a lower guide member 32. The lower guide member 32 is fixed to the mounting bracket 12 and has a second mounting groove 321. The upper guide member 31 is disposed within the second mounting groove 321. The inner wall of the second mounting groove 321 is recessed to form a plurality of guide grooves 322. The guide grooves 322 are provided with inclined first guide surfaces 323. The upper guide member 31 is provided with a plurality of positioning grooves 311 that cooperate with the guide grooves 322. The positioning grooves 311 are provided with inclined second guide surfaces 312. The rotating component 33 has a limiting shaft 332 on its side wall. One end of the rotating component 33 passes through the mounting hole 14 and the irregular hole 231, and the other end passes through the upper guide 31 and extends into the lower guide 32. When the limiting shaft 332 is located in the positioning groove 311, the first limiting plate 331 is engaged with the bottom of the essential oil bottle 20 or aligned with the irregular hole 231. The first elastic member 34 is located in the second mounting groove 321. One end of the first elastic member 34 abuts against the inner wall of the lower guide 32, and the other end abuts against the rotating component 33.

[0057] In this embodiment, the guide assembly 30 consists of an upper guide member 31 and a lower guide member 32. The lower guide member 32 is fixedly mounted on the mounting bracket 12 and has a second mounting groove 321. The upper guide member 31 is assembled into the second mounting groove 321, forming a guideable limiting structure with the lower guide member 32. The inner wall of the second mounting groove 321 has multiple guide grooves 322, each guide groove 322 having an inclined first guide surface 323 for guiding the rotation path of the limiting shaft 332 on the side wall of the rotating member 33. The upper guide member 31 has multiple positioning grooves 311 that cooperate with the guide grooves 322, and the positioning grooves 311 have second guide surfaces 312, forming a locking displacement path during rotation.

[0058] During use, when the user presses down on the essential oil bottle 20, the rotating component 33 slides and rotates along the guide surface, and the first limiting plate 331 rotates accordingly. When the limiting shaft 332 slides into the specific positioning groove 311 under the guidance of the guide component, and the first limiting plate 331 is engaged with the lower part of the essential oil bottle 20, the fixation of the essential oil bottle 20 to the diffuser body 10 is completed. When the user presses down on the essential oil bottle 20 again, the rotating component 33 continues to rotate, causing the limiting shaft 332 to slide into another adjacent positioning groove 311, thereby aligning the first limiting plate 331 with the irregular hole 231, thus unlocking and allowing the user to remove the essential oil bottle 20 from the diffuser body 10.

[0059] Furthermore, such as Figures 1 to 4 , Figure 6 and Figure 7As shown, the outer wall of the mounting bracket 12 protrudes to form a mounting base 121, and the mounting base 121 has a fixing groove 122. One end of the lower guide member 32 is fixed in the fixing groove 122. The groove wall of the second mounting groove 321 of the lower guide member 32 is recessed to form a first limiting groove 324. The outer wall of the upper guide member 31 protrudes to form a limiting ring 313 that cooperates with the first limiting groove 324. The limiting ring 313 is located in the first limiting groove 324. In this embodiment, the mounting base 121 extends outward from the outer wall of the mounting bracket 12. The mounting base 121 is integrally formed on the side of the mounting bracket 12 and is used to fix and cooperate with the lower guide member 32. The fixing groove 122 is used to limit the installation of the lower guide member 32. Specifically, it is adapted to the end shape of the lower guide member 32. One end of the lower guide member 32 is embedded in the fixing groove 122 and fastened with screws, thereby ensuring that the lower guide member 32 is stably installed in the diffuser body 10 and is not easy to loosen or shift.

[0060] The first limiting groove 324 is used to cooperate with the limiting ring 313 to fix the upper guide member 31 in the lower guide member 32. Specifically, the first limiting groove 324 extends from the opening of the second mounting groove 321 into the groove, and the limiting ring 313 is located in the first limiting groove 324 and abuts against the groove wall of the first limiting groove 324, thereby effectively restricting the upper guide member 31 from moving in the horizontal direction, thereby improving the structural stability of the pressing mechanism.

[0061] Furthermore, such as Figure 6 and Figure 7 As shown, a plurality of first limiting posts 325 are spaced apart within the first limiting groove 324, and a plurality of second limiting grooves 314 are correspondingly provided on the limiting ring 313 of the upper guide member 31; or, a plurality of second limiting grooves 314 are provided on the groove wall of the first limiting groove 324, and a plurality of first limiting posts 325 are correspondingly spaced apart on the limiting ring 313 of the upper guide member 31. In this embodiment, the first limiting posts 325 and the second limiting grooves 314 are fitted together to form a limiting fit structure, which is used to restrict the axial or circumferential movement of the upper guide member 31 within the second mounting groove 321 to achieve precise positioning.

[0062] Specifically, the first limiting post 325 is a protruding structure, arranged at intervals along the length of the first limiting groove 324. The arrangement of multiple limiting posts not only enhances the limiting stability but also provides multi-point limiting support, thereby effectively preventing the upper guide member 31 from rotating, shifting, or dislodging during the operation or movement of the diffuser with a single-twist quick-release structure. The second limiting groove 314, as a groove structure matching the first limiting post 325, is set on the limiting ring 313 (or the inner wall of the limiting groove), allowing the multiple first limiting posts 325 to accurately embed into the corresponding second limiting grooves 314 during assembly.

[0063] Through the aforementioned structural cooperation, during the pressing and installation of the essential oil bottle 20, the limiting ring 313 of the upper guide 31 can be precisely positioned with the first limiting post 325 via multiple second limiting grooves 314, thereby ensuring consistent assembly position of the guide and controlled rotation state, greatly improving the structural stability and operational reliability of the pressing mechanism. Simultaneously, the spaced arrangement of the multiple first limiting posts 325 also provides redundancy; even if tolerances accumulate or wear occurs in some positions, effective positioning can continue through other limiting posts, thus improving the durability and service life of the entire diffuser product using the single-twist quick-release structure.

[0064] Furthermore, such as Figure 6 and Figure 7 As shown, the lower guide member 32 has a second limiting post 326 protruding from one end within the fixing groove 122, and a third limiting groove 141 is formed on the inner wall of the mounting hole 14 corresponding to the second limiting post 326. In this embodiment, the second limiting post 326 serves as a limiting protrusion structure, inserted into and slidingly fitted within the third limiting groove 141, forming a guiding and limiting fit relationship to limit the movement path and position of the lower guide member 32 within the mounting hole 14. Specifically, the engagement of the second limiting post 326 with the third limiting groove 141 effectively prevents the lower guide member 32 from radially or rotationally shifting during installation, ensuring stable installation of the lower guide member 32 along a predetermined direction and avoiding structural misalignment or jamming due to excessive displacement. This fit relationship effectively improves the assembly accuracy and mechanical reliability of the overall structure.

[0065] Furthermore, such as Figure 6 and Figure 7 As shown, a limiting seat 315 protrudes from the side of the upper guide member 31 away from the lower guide member 32, and the limiting seat 315 is located within the mounting hole 14. In this embodiment, the limiting seat 315, through contact with the inner wall of the mounting hole 14, effectively restricts the radial movement of the upper guide member 31 along the mounting hole 14, preventing it from becoming loose or misaligned during use. This structural design ensures that the upper guide member 31 can maintain a stable position, guaranteeing the structural integrity and motion accuracy of the entire pressing mechanism.

[0066] Furthermore, such as Figure 2 and Figure 3As shown, the first elastic element 34 is a spring, and the outer wall of the rotating element 33 has a fourth limiting groove 333. One end of the spring is located within the fourth limiting groove 333. In this embodiment, the first elastic element 34 can also be other mounting parts with elastic deformation capabilities, such as rubber or silicone, to achieve the reset function of the rotating element 33. However, a spring is preferred as the first elastic element 34 because it has better elasticity and higher durability. One end of the spring is fitted into the fourth limiting groove 333 on the outer wall of the rotating element 33 to ensure a stable fit between the spring and the rotating element 33. The other end abuts against the bottom wall of the second mounting groove 321. The spring force enables the rotating element 33 to automatically reset after the external force is removed, ensuring the stability of the structure and the sensitivity of operation.

[0067] Furthermore, such as Figures 1 to 3 As shown, the diffuser body 10 also includes an air pump assembly, which is disposed within the first housing 11; the essential oil bottle 20 includes a second housing 21, an atomizing assembly 22, and a second limiting plate 23. The atomizing assembly 22 is disposed within the second housing 21 and communicates with the air pump assembly. The bottom of the second housing 21 is recessed to form a relief groove 211, and the second limiting plate 23 is fixed within the relief groove 211. The irregular hole 231 is formed on the second limiting plate 23. In this embodiment, the air pump assembly is used to provide a stable airflow driving force for the atomizing assembly 22, promoting the thorough mixing of essential oil and airflow to achieve effective atomization and spraying of essential oil; the second housing 21 is used to accommodate and fix the atomizing assembly 22, and at the same time communicates with the air pump assembly to form a complete airflow transmission channel. The bottom of the second housing 21 is designed with a recessed relief groove 211 to provide space for the first limiting plate 331 of the rotating component 33 to move. At the same time, the second limiting plate 23 is fixed in the relief groove 211 and has an irregular hole 231. The irregular hole 231, together with the limiting structure of the first limiting plate 331 and the rotating component 33, realizes the locking and unlocking function between the essential oil bottle 20 and the diffuser body 10, ensuring the convenience and safety of disassembly and assembly.

[0068] Furthermore, such as Figures 1 to 3As shown, the air pump assembly includes an air pump 151, a conduit 152, and an air guide rod 153. The air pump 151 is detachably installed inside the first housing 11. One end of the conduit 152 is connected to the air pump 151, and the other end is connected to the air guide rod 153. The lower guide member 32, the upper guide member 31, the rotating member 33, and the second housing 21 have through holes, and the air guide rod 153 passes through the through holes and communicates with the atomizing assembly 22. In this embodiment, the air pump 151 acts as an airflow generating device, responsible for providing stable and continuous airflow power to deliver air to the atomizing assembly 22, driving the essential oil to achieve efficient atomization. The conduit 152 connects the air pump 151 and the air guide rod 153, playing a role in airflow conduction and sealing guidance, ensuring smooth and leak-free airflow transmission. The air guide rod 153 serves as the final airflow guiding structure, directly introducing the airflow into the atomizing assembly 22, ensuring concentrated airflow and stable atomization effect.

[0069] The air pump 151 features a detachable installation design, which allows users or maintenance personnel to quickly replace the air pump 151 when it is damaged or its performance deteriorates, thereby extending the service life of the entire diffuser and reducing maintenance costs.

[0070] Furthermore, the lower guide member 32, the upper guide member 31, the rotating member 33, and the second housing 21 are all provided with through holes. These through holes are coaxially arranged to form a straight airflow channel. The air guide rod 153 passes through this coaxial through hole and communicates with the atomizing component 22. This design ensures that the air guide rod 153 is accurately positioned among the components and that the airflow transmission path is smooth, effectively avoiding airflow obstruction and leakage, and improving atomization efficiency and the overall stability of the equipment.

[0071] Furthermore, such as Figures 1 to 3 As shown, the air pump assembly further includes a second elastic element 155. The rotating component 33 has a movable groove 334. The air guide rod 153 has an abutment plate 154 at a position corresponding to the movable groove 334. The second elastic element 155 is sleeved on the air guide rod 153, with one end of the second elastic element 155 abutting against the abutment plate 154 and the other end abutting against the bottom wall of the second mounting groove 321. In this embodiment, the second elastic element 155 is used to improve the stability of the communication between the air guide rod 153 and the atomizing component 22. Specifically, the second elastic element 155 abuts against the abutment plate 154 on the air guide rod 153, which can always provide an upward supporting force for the air guide rod 153. This support ensures that the air guide rod 153 remains tightly and stably connected to the atomizing component 22 during installation, preventing loosening or displacement of the connection due to vibration or external force. This effectively improves the sealing and connectivity stability of the airflow path between the air guide rod 153 and the atomizing component 22, ensuring the continuous and stable atomization effect of the diffuser.
