Technical Field

[0001] This utility model relates to the field of aromatherapy technology, specifically an aromatherapy diffuser that facilitates the full release of fragrances. Background Technology

[0002] Aromatherapy has a long history and was often used by the ancients as a daily necessity for health preservation and cultivating their mind. Modern pharmacological research has proven that certain aromatherapy products have antibacterial, disinfectant, calming, and health-preserving effects. Therefore, aromatherapy still exists in people's lives and health care today.

[0003] Aroma diffusers, also known as essential oil diffusers, fragrance diffusers, or incense burners, are devices that convert fragrances such as incense, essential oils, and incense liquids into gas through heating and atomization. They are commonly used aromatherapy devices.

[0004] In existing electric aromatherapy diffusers, when using solid fragrances such as granules or powders, the fragrance remains stationary throughout the heating process after being added. This prevents fragrances far from the heat source or those piled up inside from being fully heated and releasing their aroma, resulting in insufficient use of the fragrance and waste. Furthermore, the fragrance release is not sustained, affecting the user experience.

[0005] Therefore, we need to design an aromatherapy diffuser that allows for the full release of fragrance. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an aromatherapy burner that facilitates the full release of fragrances. The aromatherapy burner utilizes a structural design that allows the fragrances to be stirred and turned during the heating process, thereby keeping the accumulated fragrances in motion and ensuring that the fragrances are heated more comprehensively and fully, thus guaranteeing that the fragrances are fully heated and release their aroma.

Several stirring blades are arranged at the bottom of the stirring drum. A magnetic stir bar is also fixed at the bottom of the stirring drum. The furnace body is located below the cylindrical heating chamber and is equipped with a drive motor and a permanent magnet connected to the output shaft of the drive motor. The permanent magnet and the magnetic stir bar are both horizontally arranged and face each other. The permanent magnet can rotate under the drive motor to drive the magnetic stir bar to rotate through magnetic force, and the magnetic stir bar synchronously drives the stirring drum to rotate circumferentially.

[0008] Based on the above technical solution, the upper cylinder and the lower cylinder are connected as one unit by threads; the top wall of the stirring cylinder protrudes outward to form a leak-proof retaining ring, and an annular groove is provided at the lower end of the upper cylinder. When the upper cylinder and the lower cylinder are connected as one unit, the leak-proof retaining ring is installed in the annular groove to form a paired structure.

[0009] Based on the above technical solution, a positioning groove is provided at the middle position of the bottom of the mounting groove, and a rolling bearing is provided in the positioning groove. A positioning shaft is also provided at the middle position of the bottom of the stirring cylinder. The positioning shaft is positioned in the positioning groove and is inserted into the inner ring of the rolling bearing to form a pair. A sliding bearing is also provided at the bottom of the mounting groove outside the positioning groove, and the bottom of the stirring cylinder is slidably supported on the sliding bearing.

[0010] Based on the above technical solution, a heat-insulating positioning ear is also provided on the outer side of the top of the upper cylinder, and two positioning plates are also provided opposite to each other on the top of the furnace body, forming a positioning notch between the positioning plates.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model utilizes an electric heating element to heat the circumference of the heat-conducting fragrance cylinder over a large area, thereby increasing the heating area and heat of the fragrance, making the fragrance more fully and completely heated, fully releasing the fragrance, increasing its utilization rate, improving the fragrance diffusion effect, and making the fragrance more lasting.

[0019] 2. This utility model utilizes a drive motor, a permanent magnet, and a magnetic stir bar to form a magnetic stirring structure. The drive motor and permanent magnet can drive the magnetic stir bar to rotate, which in turn drives the stirring drum to rotate. This causes the spices inside to rotate under the action of the stirring drum, and the position of the spices is dynamically changing. Under the action of the stirring blades, the disturbance at the bottom of the spices increases, and the entire pile of spices will move with the rotation of the stirring drum and can perform a certain up-and-down movement. This not only increases the heat received by the spices, but also solves the problem that the spices cannot be heated inside and thus cannot release their aroma. This further improves the utilization rate of the spices and ensures the aroma release effect of the spices.

[0020] 3. The heat-conducting fragrance cylinder of this utility model has a movable connection design between the upper cylinder and the lower cylinder, which makes the entire heat-conducting fragrance cylinder not only easy to load, unload and assemble, but also easy to clean. The stirring cylinder can also be easily removed, replaced or cleaned, which increases the overall convenience of using the aromatherapy diffuser. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] The aromatherapy diffuser in this embodiment is mainly used for heating various solid aromatherapy products such as blocks, strips, granules or powders, and can be applied to many fields such as aromatherapy care, aromatherapy, respiratory therapy, and health preservation.

[0034] like Figures 1 to 8As shown, this embodiment of the aroma diffuser, which facilitates the full release of fragrance, includes at least a diffuser body 1 and a diffuser cover 2. The diffuser cover 2 is placed on the diffuser body 1. The diffuser body 1 has a cylindrical heating chamber 3 with an opening at the top. The circumferential sidewall of the cylindrical heating chamber 3 is also embedded with an electric heating element 4. The diffuser cover 2 has several aroma outlets 5 that communicate with the cylindrical heating chamber 3. A heat-conducting fragrance cylinder 6 is placed inside the cylindrical heating chamber 3 and can be inserted or removed from the top opening. The heat-conducting fragrance cylinder 6 includes an upper cylinder 7 and a lower cylinder 8 that are movably connected. The top of the lower cylinder 8 is recessed to form an installation groove. 9. A rotatable stirring drum 10 is installed in the mounting slot 9. Several stirring blades 11 are provided at the bottom of the stirring drum 10. A magnetic stir bar 12 is also fixed at the bottom of the stirring drum 10. The furnace body 1 is located below the cylindrical heating chamber 3 and is also provided with a drive motor 13 and a permanent magnet 14 connected to the output shaft of the drive motor 13. The permanent magnet 14 and the magnetic stir bar 12 are both horizontally arranged and face each other. The permanent magnet 14 can rotate under the drive motor 13 to drive the magnetic stir bar 12 to rotate through magnetic force, and the magnetic stir bar 12 synchronously drives the stirring drum 10 to rotate circumferentially.

[0035] When in use, remove the furnace lid 2 and take out the heat-conducting fragrance cylinder 6 to pour in the fragrance, or pour the fragrance directly into the heat-conducting fragrance cylinder 6. Then close the furnace lid 2. At this time, the electric heating element 4 can be turned on to heat the heat-conducting fragrance cylinder 6. The heat-conducting fragrance cylinder 6 is heated and transfers heat to the interior, causing the fragrance inside to release its aroma. The aroma is then discharged from the aroma outlet 5. During the heating process, the drive motor 13 can also be turned on simultaneously to drive the permanent magnet 14 to rotate. When the permanent magnet 14 rotates, the magnetic field changes regularly. Under the influence of the regularly changing magnetic field, the magnetic stir bar 12 will also rotate, thereby driving the magnetic stir bar 12, which is fixed to the permanent magnet 14, to rotate. The stirring drum 10 rotates horizontally within the mounting groove 9. The fragrance located in the heat-conducting fragrance cylinder 6 is dynamically disturbed or turned over by the stirring drum 10 and stirring blades 11, so that the fragrance is not stationary within the heat-conducting fragrance cylinder 6. Furthermore, the stirring drum 10 is located at the bottom of the heat-conducting fragrance cylinder 6, which can further push the fragrance to move in a circular and vertical direction. This allows the fragrance accumulated inside to move up, down, left, and right under the stirring, thereby increasing the heating area and heat of the fragrance. This makes the fragrance more fully and completely heated, resulting in full release of fragrance, high utilization rate, good fragrance diffusion effect, and longer-lasting aroma.

[0036] After use, the furnace cover 2 can be opened and the heat-conducting fragrance cylinder 6 can be taken out to pour out the waste fragrance for reuse. When cleaning or replacement is required, the heat-conducting fragrance cylinder 6 can be taken out and disassembled into the upper cylinder 7 and the lower cylinder 8. At this time, the stirring cylinder 10 can be taken out from the installation slot 9, so that the upper cylinder 7, the lower cylinder 8 and the stirring cylinder 10 can be cleaned or replaced respectively. The overall structure is extremely convenient to use and disassemble.

[0037] In application, both the furnace body 1 and the furnace cover 2 can be configured as cylindrical structures, and they can be paired together using threads, snap-fit ​​mechanisms, or other methods. Furthermore, the furnace body 1 and the furnace cover 2 are detachably connected via threads. Additionally, both the furnace body 1 and the furnace cover 2 are made of rigid PVC plastic.

[0038] In application, the bottom of the stirring drum 10 is also provided with a slot, in which the magnetic stir bar 12 can be locked, thereby achieving a stable connection. Furthermore, the magnetic stir bar 12 can be a glass magnetic stir bar or a polyethylene tetroxide magnetic stir bar.

[0039] It should be noted that the drive motor 13, permanent magnet 14 and magnetic stirrer 12 together constitute a magnetic stirring structure, which is similar to the magnetic stirring structure and principle in the prior art and belongs to the existing mature technology. Therefore, the specific structure and principle of the three will not be further explained in this embodiment. Those skilled in the art can implement it based on the existing magnetic stirring structure, and will not be elaborated here.

[0040] like Figure 7 , Figure 8 As shown, the upper cylinder 7 and the lower cylinder 8 are connected as one piece by threads; the top wall of the stirring cylinder 10 protrudes outward to form a leak-proof retaining ring 15, and the lower end of the upper cylinder 7 is provided with an annular groove 16. When the upper cylinder 7 and the lower cylinder 8 are connected as one piece, the leak-proof retaining ring 15 is installed in the annular groove 16 to form a paired structure.

[0041] During use, due to the rotation of the mixing drum 10, the internal fragrance, especially the powdered fragrance, is prone to leak into the mounting groove 9, which increases the rotational resistance of the mixing drum 10 and affects its normal rotation. Alternatively, the fragrance may also easily leak out of the lower drum 8 and contaminate the cylindrical heating chamber 3, affecting its use.

[0042] Based on this, this embodiment designs a leak-proof retaining ring 15 on the top wall of the mixing drum 10. It is paired with the annular groove 16 and forms a sealing annular groove structure under the force of the threaded connection between the upper cylinder 7 and the lower cylinder 8. The design of the leak-proof retaining ring 15 can block the fragrance, effectively prevent the fragrance from leaking, ensure the cleanliness of the whole device during use, and ensure the normal rotation of the mixing drum 10.

[0043] Continue reading Figure 7 , Figure 8The mounting groove 9 has a positioning groove 17 at the bottom center, and a rolling bearing 18 is provided in the positioning groove 17. The stirring cylinder 10 also has a positioning shaft 19 at the bottom center. The positioning shaft 19 is positioned in the positioning groove 17 and is inserted into the inner ring of the rolling bearing 18 to form a pair. The bottom of the mounting groove 9 is also provided with a sliding bearing 20 outside the positioning groove 17, and the bottom of the stirring cylinder 10 is slidably supported on the sliding bearing 20.

[0044] To ensure better circumferential rotation of the mixing drum 10, this embodiment uses the design of positioning shaft 19 and positioning groove 17 to ensure that the circumferential rotation trajectory of the mixing drum 10 is constant. The positioning shaft 19 is rotated by pairing with rolling bearing 18, and the rotation of the positioning shaft 19 is ensured by using sliding bearing 20. The combination of the two bearings reduces the friction force experienced by the mixing drum 10 during rotation, and the entire rotation process is easier to achieve and execute.

[0045] like Figure 4 As shown, the upper cylinder 7 is also provided with a heat-insulating positioning ear 21 on the outer side of the top, and two positioning plates 22 are also provided opposite to each other on the top of the furnace body 1. A positioning notch 23 is formed between the positioning plates 22. When the heat-conducting fragrance cylinder 6 is placed in the cylindrical heating chamber 3, the heat-insulating positioning ear 21 is engaged in the positioning notch 23.

[0046] When the stirring drum 10 rotates during use, it may cause the entire heat-conducting fragrance cylinder 6 to rotate, which may lead to the failure of the stirring drum 10 or prevent the entire stirring drum 10 from rotating. Therefore, in this embodiment, by setting the heat-insulating positioning ear 21 to match the positioning notch 23, the heat-conducting fragrance cylinder 6 is snapped and positioned in the cylindrical heating chamber 3. This not only prevents the upper cylinder 7 and lower cylinder 8 from rotating, but also ensures that the heat-conducting fragrance cylinder 6 can be stably placed in the cylindrical heating chamber 3 without shaking due to the rotation of the stirring drum 10, thus ensuring the stability of the device. At the same time, when the heat-conducting fragrance cylinder 6 needs to be removed after heating, the heat-insulating positioning ear 21 also has a heat insulation effect, so that a person can hold the positioning ear 21 to remove the entire heat-conducting fragrance cylinder 6 without burning their hands, thus ensuring good safety.

[0047] As one specific implementation, the heat-insulating positioning ear 21 is made of heat-insulating materials, such as alumina ceramic, rigid polyurethane foam, polyethylene plastic material, etc.

[0048] In one specific implementation, the upper cylinder 7, lower cylinder 8, and stirring cylinder 10 are all made of silicon nitride ceramic. Silicon nitride ceramic, with its high thermal conductivity, can quickly transfer the heat generated by the electric heating element 4 to the interior to heat the fragrance, ensuring effective fragrance heating.

[0049] like Figure 3 , Figure 6As shown, the furnace body 1 has an opening at the bottom of the cylindrical heating chamber 3 for an electrical component installation chamber 24. The drive motor 13 and the permanent magnet 14 are installed in the electrical component installation chamber 24. The furnace body 1 also has an openable and closable sealing plate 25 at the opening of the electrical component installation chamber 24.

[0050] In application, in order to facilitate the installation and removal of electrical components inside the furnace body 1 and to better isolate them from the heat generated by the electric heating element 4, the furnace body 1 in this embodiment has a separate electrical component installation compartment 24 at the bottom for installing the drive motor 13 and the permanent magnet 14. This can effectively isolate heat and ensure the normal use of electrical components. At the same time, the openable structure also facilitates the installation, removal and replacement of the drive motor 13 and the permanent magnet 14.

[0051] Based on this, a heat insulation layer is provided on the top of the electrical component mounting chamber 24. In this embodiment, the heat insulation layer can effectively isolate the heat transfer and influence of the cylindrical heating chamber 3 during the heating process, further ensuring the safety of the electrical components inside the electrical component mounting chamber 24.

[0052] Based on this, an electrical component positioning mounting plate 26 is also installed inside the electrical component mounting compartment 24. The electrical component positioning mounting plate 26 can be removed through the opening of the electrical component mounting compartment 24; the drive motor 13 is mounted on the electrical component positioning mounting plate 26. In order to further facilitate the loading, unloading and replacement of electrical components, this embodiment uses the electrical component positioning mounting plate 26 to unify the installation structure of electrical components. Thus, when needed, the electrical component positioning mounting plate 26 can be removed as a whole from the electrical component mounting compartment 24 for loading, unloading and replacement of electrical components, avoiding the inconvenience caused by the small space inside the electrical component mounting compartment 24.

[0053] Continue reading Figure 3 , Figure 6 The electrical component installation compartment 24 is also equipped with a storage battery 27 and a controller 28; the electric heating element 4 and the drive motor 13 are both electrically connected to the controller 28, and the controller 28 is electrically connected to the storage battery 27; the front and back of the furnace body 1 are respectively equipped with a charging interface 29 and a touch screen display 30, and both the charging interface 29 and the touch screen display 30 are electrically connected to the controller 28.

[0054] In use, the battery 27 provides power to all electrical components, while the controller 28 controls the opening and closing and power of each component, such as controlling the heating power of the electric heating element 4 and the speed of the drive motor 13. The charging interface 29 is used to connect to an external power source or to charge the battery 27. The touch screen 30 is used to interact with the user, displaying heating temperature, drive motor speed, working status, battery level, etc., and provides touch-sensitive buttons for customers to select functions, including the on / off button for the aroma diffuser, the heating temperature control button, the speed control button, etc. Thus, through the cooperation of the above electrical components, the aroma diffuser becomes more convenient and intelligent to use.

[0055] Based on this, when the electrical component positioning and mounting plate 26 is present, the battery 27 and the controller 28 can both be installed on the electrical component positioning and mounting plate 26.

[0056] As one specific implementation method, quick plugs can be set for the connection lines of the electric heating element 4, drive motor 13, charging interface 29, and touch display screen 30. The controller 28 can be set with a corresponding quick plug socket to achieve quick plug-in. In addition, it is also convenient to disconnect all circuit connections when the electrical component positioning and mounting plate 26 is removed, so as to achieve quick loading and unloading.

[0057] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
