Description

Technical Field

[0001] This invention belongs to the field of aromatherapy technology, specifically relating to an aromatherapy structure, a heater and its air outlet assembly. Background Technology

[0002] Currently, space heaters are common household appliances widely used for winter heating. Traditional space heaters primarily heat the air, but some modern models also incorporate aromatherapy components. These components consist of an aromatherapy box and an aromatherapy carrier. The carrier holds the aromatic substances and allows the scent produced by their volatilization to diffuse outwards. The carrier is typically located inside the aromatherapy box and is fixed to the aroma diffuser section. When the space heater blows hot air within a preset temperature range, the temperature of the aroma diffuser section rises, potentially burning the aromatherapy carrier. Therefore, this issue needs to be addressed. Summary of the Invention

[0003] Therefore, the present invention provides an aromatherapy structure, a heater and its air outlet assembly, which can solve the technical problem in the prior art that when the heater blows hot air within a preset temperature range, the temperature of the aroma diffuser part of the aromatherapy box is affected and rises accordingly, easily scorching the aromatherapy carrier.

[0004] To address the aforementioned problems, the present invention provides an aromatherapy structure comprising an aromatherapy box and an aromatherapy carrier; the aromatherapy carrier is configured to carry aromatherapy substances and to allow the odor generated by the volatilization of the aromatherapy substances to diffuse to the outside of the aromatherapy carrier; the aromatherapy box has a fragrance dispersing section with a first fragrance dispersing hole; the aromatherapy carrier is movably disposed within the aromatherapy box and opposite to the fragrance dispersing section; wherein, the aromatherapy structure further includes a position adjustment mechanism for driving the aromatherapy carrier to move, so as to drive the aromatherapy carrier away from the fragrance dispersing section from its initial position when the temperature of the fragrance dispersing section rises to a first preset temperature range.

[0005] In some embodiments, within the first preset temperature range, the higher the temperature of the fragrance dispersing part, the more the position adjustment mechanism drives the fragrance carrier to move to a position farther away from the fragrance dispersing part.

[0006] In some embodiments, the position adjustment mechanism is also used to drive the aromatherapy carrier back to the initial position when the temperature of the fragrance diffuser returns to the initial preset temperature range.

[0007] In some embodiments, the position adjustment mechanism includes a bimetallic component that is thermally connected to the fragrance diffuser; wherein the bimetallic component includes a first metal member and a second metal member stacked together, the first metal member having a greater coefficient of thermal expansion than the second metal member, and the bimetallic component is configured to bend toward the second metal member when heated and expanding; wherein the position adjustment mechanism drives the fragrance carrier to move through the bimetallic component.

[0008] In some embodiments, the bimetallic component is disposed on the aromatherapy box and connected to the aromatherapy carrier via the first metal member; wherein, the bimetallic component is disposed on the side of the aromatherapy carrier opposite to the fragrance dispersing part, and the first metal member is located between the aromatherapy carrier and the second metal member.

[0009] In some embodiments, the position adjustment mechanism is further configured to drive the aromatherapy carrier from the initial position toward the aromatherapy portion when the temperature of the fragrance diffuser drops to a second preset temperature range; wherein the temperature in the second preset temperature range is lower than the temperature in the initial preset temperature range.

[0010] In some embodiments, within the second preset temperature range, the lower the temperature of the fragrance dispersing part, the more the position adjustment mechanism drives the fragrance carrier to move to a position closer to the fragrance dispersing part.

[0011] In some embodiments, when the position adjustment mechanism includes a bimetallic component and the bimetallic component is thermally connected to the fragrance diffuser; the bimetallic component includes a first metal part and a second metal part stacked together, the coefficient of thermal expansion of the first metal part being greater than that of the second metal part, and when the position adjustment mechanism drives the fragrance carrier to move through the bimetallic component, the bimetallic component is configured to bend toward the first metal part when it contracts upon cooling.

[0012] In some embodiments, the aromatherapy substance is an aromatherapy oil, and the aromatherapy carrier is an oil-absorbing elastic block; wherein, the aromatherapy structure further includes a heat-sensitive element, which is used to expand as the temperature rises and contract as the temperature falls within a third preset temperature range; the heat-sensitive element is connected to the aromatherapy carrier so as to drive the aromatherapy carrier to expand or contract together.

[0013] In some embodiments, the heat-sensitive element is embedded in the aromatherapy carrier or laminated onto the surface of the aromatherapy carrier by means of adhesive; wherein, the heat-sensitive element is provided with a second fragrance dispersing hole.

[0014] In some embodiments, the fragrance dispersing part is provided with a fragrance substance addition hole; And / or, the aromatherapy box has a lid and a box body, the fragrance diffuser is disposed on the lid, and the aromatherapy carrier is disposed in the box body; wherein, the lid is detachable from the box body, and when the lid is detached from the box body, the aromatherapy carrier can be installed or removed through the opening of the box body.

[0015] The present invention also provides an air outlet assembly for a heater, which includes the aromatherapy structure described in any one of the above-mentioned methods.

[0016] In some embodiments, the air outlet assembly has an air outlet side, and the aromatherapy box has a receiving groove, through which the aromatherapy carrier is received; wherein the receiving groove is located on the upper part of the air outlet side.

[0017] In some embodiments, when the aromatherapy box has a lid and a body, and the fragrance diffuser is disposed on the lid and the aromatherapy carrier is disposed in the body, the air outlet assembly has an air outlet duct component, and the air outlet assembly outlets air through the air outlet duct component; wherein the air outlet duct component forms the body.

[0018] In some embodiments, the air outlet assembly of the heater further includes a mesh cover that fastens to the air outlet side of the air outlet duct component; wherein the area of ​​the mesh cover corresponding to the fragrance diffuser has a window opening, and the cover can be detached from the window opening.

[0019] The present invention also provides a heater that includes the aromatherapy structure described in any one of the above descriptions; or includes the air outlet component described in any one of the above descriptions.

[0020] In some embodiments, the heater is supported by a support structure; when the heater is supported on a horizontal surface by the support structure, the angle α between the centerline of the air outlet and the horizontal surface is from ° to °.

[0021] In some embodiments, the support structure includes a first leg, a second leg, and a third leg, all of which have the same structure; the first leg and the second leg are symmetrically arranged; the third leg is located above both the first leg and the second leg, and is connected to the body of the heater via an adapter.

[0022] The aromatherapy structure, heater, and air outlet assembly provided by this invention have the following beneficial effects: 1. The present invention uses a position adjustment mechanism to drive the fragrance carrier away from the fragrance carrier from its initial position when the temperature of the fragrance dispersing part rises to a first preset temperature range. This helps to maintain a safe distance between the fragrance carrier and the fragrance dispersing part and reduces the risk of the fragrance carrier being burned by the high temperature of the fragrance dispersing part.

[0023] 2. This invention incorporates a heat-sensitive element on the aromatherapy carrier. When the heater is activated, the hot air from the heater raises the ambient air temperature. When the temperature at the heat-sensitive element reaches a second preset temperature range, the heat-sensitive element expands, causing the oil-absorbing elastic block to expand as well. This increases the contact area between the oil-absorbing elastic block and the hot air, automatically accelerating the release rate of aromatherapy molecules. When the temperature decreases (e.g., at a low fan speed setting), the heat-sensitive element contracts, causing the oil-absorbing elastic block to contract as well. This reduces the contact area, automatically slowing down the release rate.

[0024] 3. This invention makes it easy to assemble and disassemble the aromatherapy structure on the heater. Furthermore, by placing the aromatherapy carrier in a container located directly above the heater's air outlet, the high-temperature environment at the outlet makes the aromatherapy molecules move more actively, thereby improving the aromatherapy's evaporation efficiency and achieving a better fragrance diffusion effect.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0030] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0031] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0032] See also Figure 1-3 As shown, according to an embodiment of the present invention, an aromatherapy structure is provided, which includes an aromatherapy box 1 and an aromatherapy carrier 2. The aromatherapy carrier 2 is configured to carry aromatherapy substances and allow the scent generated by the evaporation of the aromatherapy substances to diffuse to the outside of the aromatherapy carrier 2. The aromatherapy carrier 2 can be an oil-absorbing cotton block, etc. The aromatherapy box 1 has a fragrance dispersing part 11, and the fragrance dispersing part 11 is provided with a first fragrance dispersing hole 101. The aromatherapy carrier 2 is movably disposed inside the aromatherapy box 1 and opposite to the fragrance dispersing part 11, so that the scent generated by the evaporation of the aromatherapy substances can be diffused through the first fragrance dispersing hole 101.

[0033] The aromatherapy structure also includes a position adjustment mechanism, which is used to drive the aromatherapy carrier 2 to move away from the aromatherapy carrier 2 from the initial position when the temperature of the fragrance dispersing part 11 rises to a first preset temperature range.

[0034] In the above example, when the aromatherapy structure is applied to a heater, the first preset temperature range can be matched with the temperature of the heater's hot air output. This invention, by setting a position adjustment mechanism, drives the aromatherapy carrier 2 away from the aromatherapy section 11 when the temperature of the aromatherapy section 11 rises to the first preset temperature range. This helps maintain a safe distance between the aromatherapy carrier 2 and the aromatherapy section 11, reducing the risk of the aromatherapy carrier 2 being burned by the high temperature of the aromatherapy section 11.

[0035] In some embodiments, within the aforementioned first preset temperature range, the higher the temperature of the fragrance diffuser 11, the more the position adjustment mechanism drives the fragrance carrier 2 to move to a position farther away from the fragrance diffuser 11. This is more conducive to maintaining a safe distance between the fragrance carrier 2 and the fragrance diffuser 11, further reducing the risk of the fragrance carrier 2 being burned by the high-temperature fragrance diffuser 11.

[0036] It should be noted that within the first preset temperature range, the lower the temperature of the fragrance dispersing part 11, the closer the fragrance carrier 2 is to the fragrance dispersing part 11. In this way, while ensuring a safe distance, the efficiency of the fragrance carrier 2 in dispersing fragrance through the first fragrance dispersing hole 101 on the fragrance dispersing part 11 can be improved.

[0037] In some embodiments, the aforementioned position adjustment mechanism is also used to drive the fragrance carrier 2 back to its initial position when the temperature of the fragrance dispersing section 11 returns to the initial preset temperature range, so as to avoid the fragrance carrier 2 being too far away from the fragrance dispersing section 11 and affecting the efficiency of fragrance dispersal when the temperature is within the initial preset temperature range. It should be noted here that the temperature within the initial preset temperature range is lower than the temperature within the aforementioned first preset temperature range.

[0038] To achieve the aforementioned function of the position adjustment mechanism, in some embodiments, such as Figure 1-6 As shown, the aforementioned position adjustment mechanism may include a bimetallic component 4. This bimetallic component 4 is thermally connected to the fragrance diffuser 11, enabling it to sense the temperature of the fragrance diffuser 11. The bimetallic component 4 includes a first metal element 41 and a second metal element 42 stacked together. The coefficient of thermal expansion of the first metal element 41 is greater than that of the second metal element 42. The bimetallic component 4 is configured to bend towards the second metal element 42 when heated and expanding. The position adjustment mechanism drives the fragrance carrier 2 to move via the bimetallic component 4.

[0039] The working principle of the thermal expansion of the bimetallic component 4 is the same as that of the bimetallic sheet in the prior art, so the working principle of the thermal expansion of the bimetallic component 4 will not be described again here.

[0040] In the above example, the bimetallic component 4 can realize the function of the aforementioned position adjustment mechanism, so as to drive the fragrance carrier 2 away from the fragrance dispersing part 11 when the temperature of the fragrance dispersing part 11 rises to the first preset temperature range. Within the first preset temperature range, the higher the temperature of the fragrance dispersing part 11, the farther the fragrance carrier 2 is from the fragrance dispersing part 11.

[0041] In some implementations, such as Figure 1-3As shown, the aforementioned bimetallic component 4 is disposed on the aromatherapy box 1 and connected to the aromatherapy carrier 2 via a first metal part 41. For example, the first metal part 41 and the aromatherapy carrier 2 can be bonded together. The bimetallic component 4 is disposed on one side of the aromatherapy carrier 2 with the fragrance-dispersing part 11 on the back, and the first metal part 41 is located between the aromatherapy carrier 2 and the second metal part 42.

[0042] In the above example, when the temperature of the fragrance diffuser 11 rises to the first preset temperature range, the heat on the fragrance diffuser 11 is conducted to the bimetallic component 4. The bimetallic component 4 expands due to heat and bends toward the second metal part 42, so as to drive the fragrance carrier 2 away from the fragrance diffuser 11.

[0043] In some embodiments, the bimetallic component 4 is disposed on the housing 12 of the aroma diffuser box 1 to achieve a heat-conductive connection with the fragrance diffuser 11 via the housing 12. Specifically, the bimetallic component 4 can be fixed to the housing 12 of the aroma diffuser box 1 using threaded fasteners such as screws.

[0044] It should be noted that the heat deformation temperature range of the bimetallic component 4 mentioned above matches the first preset temperature range. In a specific application example, the heat deformation temperature range of the bimetallic component 4 is 35℃~55℃ (matching the hot air temperature range of the heater), and the deformation is 0~1.5mm.

[0045] In a specific application example, the aforementioned first metal part 41 can be made of copper, while the second metal part 42 can be made of steel. Copper has a greater coefficient of thermal expansion than steel.

[0046] It should be noted here that: in one example, the aforementioned bimetallic component 4 can be a bimetallic sheet. In another example, such as... Figure 4 As shown, both the first metal part 41 and the second metal part 42 can be columnar, so that both the first metal part 41 and the second metal part 42 have sufficient structural strength, thereby making the bimetallic component 4 strong and able to provide stable support for the aromatherapy carrier 2.

[0047] In some embodiments, the aforementioned position adjustment mechanism is also used to drive the fragrance carrier 2 from its initial position closer to the fragrance dispersing section 11 when the temperature of the fragrance dispersing section 11 drops to a second preset temperature range. The temperature within the second preset temperature range is lower than the temperature within the initial preset temperature range.

[0048] In the above example, when the aromatherapy structure is applied to a heater with a cooling function, the aforementioned second preset temperature range can be matched with the cooling air temperature of the heater. This invention, by setting a position adjustment mechanism, drives the aromatherapy carrier 2 from its initial position closer to the aromatherapy carrier 11 when the temperature of the aromatherapy section 11 drops to the second preset temperature range. This improves the efficiency of the aromatherapy carrier 2 in dispersing fragrance through the first aroma dispersing hole 101 on the aromatherapy section 11.

[0049] In some embodiments, within the second preset temperature range, the lower the temperature of the fragrance dispersing part 11, the more the position adjustment mechanism drives the fragrance carrier 2 to move to a position closer to the fragrance dispersing part 11, thereby further improving the efficiency of the fragrance carrier 2 in dispersing fragrance through the first fragrance dispersing hole 101 on the fragrance dispersing part 11.

[0050] In some embodiments, when the aforementioned position adjustment mechanism includes a bimetallic component 4 and the bimetallic component 4 is thermally connected to the fragrance dispersing part 11; the bimetallic component 4 includes a first metal part 41 and a second metal part 42 stacked together, the coefficient of thermal expansion of the first metal part 41 is greater than the coefficient of thermal expansion of the second metal part 42, and when the position adjustment mechanism drives the fragrance carrier 2 to move through the bimetallic component 4, the bimetallic component 4 is also configured to bend toward the first metal part 41 when it is cooled and contracted.

[0051] The working principle of the bimetallic component 4 under cold contraction is the same as that of the bimetallic sheet in the prior art, so the working principle of the bimetallic component 4 under cold contraction will not be described again here.

[0052] In the above example, the bimetallic component 4 can realize the function of the aforementioned position adjustment mechanism, so as to drive the fragrance carrier 2 closer to the fragrance dispersing part 11 when the temperature of the fragrance dispersing part 11 drops to the second preset temperature range. Within the second preset temperature range, the lower the temperature of the second fragrance dispersing part 11, the closer the fragrance carrier 2 is to the fragrance dispersing part 11.

[0053] It should be noted that the cold deformation temperature range of the bimetallic component 4 is matched with the second preset temperature range.

[0054] In some embodiments, the aforementioned aromatherapy substance can be an essential oil, and the aforementioned aromatherapy carrier 2 can be an oil-absorbing elastic block, such as an oil-absorbing cotton block. Figure 2-3 As shown, the aromatherapy structure of the present invention also includes a heat-sensitive element 3. The heat-sensitive element 3 is used to expand as the temperature rises within a third preset temperature range and to contract as the temperature falls. The heat-sensitive element 3 is connected to the aromatherapy carrier 2 so as to cause the aromatherapy carrier 2 to expand or contract together.

[0055] The aforementioned third preset temperature range can be matched with the hot air outlet temperature range of the heater. In a specific application example, the hot air outlet temperature range of the heater is 35℃-55℃, and the third preset temperature range is 30℃-50℃.

[0056] In the example above, when the heater is turned on, the hot air from the heater raises the ambient air temperature. When the temperature at the heat-sensitive element 3 rises to the third preset temperature range, the heat-sensitive element 3 expands, causing the aromatherapy carrier 2 to expand as well. This increases the contact area between the aromatherapy carrier 2 and the hot air, automatically accelerating the release rate of aromatherapy molecules. When the temperature decreases (e.g., at a low fan speed setting), the heat-sensitive element 3 contracts, causing the aromatherapy carrier 2 to contract as well. This reduces the contact area, automatically slowing down the release rate.

[0057] The above settings allow the release rate of the essential oils to adapt to temperature changes, creating a dynamic linkage with the overall temperature system of the heater.

[0058] In a specific application example, such as Figure 10-11 As shown, the aforementioned heat-sensitive element 3 can be in sheet form, in which case it can also be referred to as a heat-sensitive elastic film. The heat-sensitive element 3 is embedded in the aromatherapy carrier 2 or laminated onto the surface of the aromatherapy carrier 2 by means of adhesion. The heat-sensitive element 3 is provided with a second fragrance dispersing hole 31 to reduce the impact on the volatilization of the aromatherapy substance.

[0059] The aforementioned heat-sensitive element 3 can be made of thermoplastic polyurethane material.

[0060] The number of the aforementioned second fragrance dispersing holes 31 can be two or more, and they are evenly distributed on the heat-sensitive element 3.

[0061] In some implementations, such as Figure 7-8 As shown, the aforementioned fragrance diffuser 11 may be provided with a fragrance substance addition hole 102. In this way, when the fragrance substance is used up, fragrance substance can be added directly into the fragrance box 1 through the fragrance substance addition hole 102 on the fragrance diffuser 11 without disassembling the fragrance box 1.

[0062] In some embodiments, the aforementioned aromatherapy substance can be aromatherapy oil. The aromatherapy substance addition hole 102 is opposite to the middle of the aromatherapy carrier 2 to facilitate the aromatherapy oil to drip onto the aromatherapy carrier 2 and then diffuse in all directions.

[0063] The aforementioned first fragrance dispersing holes 101 can be two or more, and are arranged around the fragrance substance adding hole 102. The diameter of the fragrance substance adding hole 102 is larger than the diameter of the first fragrance dispersing hole 101.

[0064] In some embodiments, the aforementioned aromatherapy box 1 has a lid and a box body 12. The aforementioned fragrance diffuser 11 is disposed on the lid, and the aromatherapy carrier 2 is disposed inside the box body 12. The lid is detachable from the box body 12, and when the lid is detached from the box body 12, the aromatherapy carrier 2 can be installed or removed through the opening in the box body 12.

[0065] Existing aromatherapy structures are mostly fixed, making them inconvenient to replace and clean, resulting in inconvenience and affecting user experience. This invention, however, allows the lid to be detached from the body 12. Once the lid is removed from the body 12, the aromatherapy carrier 2 can be installed or removed through the opening in the body 12. This facilitates the replacement or maintenance of the aromatherapy carrier 2 and also makes cleaning of the lid and the inside of the body 12 easier.

[0066] In some embodiments, the aforementioned lid can be detachably connected to the box body 12 via snap-fit ​​fasteners. Specifically, the lid can be fastened to the box body 12 via two symmetrical snap-fit ​​structures.

[0067] In some embodiments, the present invention also provides an air outlet assembly for a heater, which may include the aromatherapy structure described above.

[0068] In some implementations, such as Figure 7 As shown, the aforementioned air outlet assembly has an air outlet side 17, and the aforementioned aromatherapy box 1 has a receiving groove 121, through which the aromatherapy box 1 receives the aromatherapy carrier (2); wherein, the receiving groove 1 is located on the upper part of the air outlet side 17.

[0069] In existing technologies, some space heaters, while incorporating aromatherapy structures, typically place the aromatherapy device inside the unit or near the air inlet 151, resulting in low aroma evaporation efficiency. This invention, however, positions the aromatherapy carrier 2's container 121 at the upper part of the air outlet 17. The hot air from the outlet 17 converges directly upwards, significantly raising the temperature at the location of the container 121. This hot air environment effectively promotes the thermal motion of aromatherapy substances, such as essential oil molecules within the aromatherapy oil, within the container 121, increasing the aroma evaporation rate and optimizing the aroma diffusion effect.

[0070] It should be noted that when the aromatherapy box 1 has a lid and a body 12, the aforementioned receiving groove 121 is provided on the body 12.

[0071] In some implementations, such as Figure 12 As shown, when the aromatherapy box 1 has a lid and a body 12, and the fragrance diffuser 11 is disposed on the lid, and the aromatherapy carrier 2 is disposed inside the body 12, the air outlet assembly has an air outlet duct component 6, through which the air outlet assembly discharges air. The air outlet duct component 6 has an air outlet 61, and the air outlet duct component 6 forms the aforementioned body 12.

[0072] In the above example, by forming the air outlet duct component 6 of the heater into the box body 12 of the aromatherapy box 1, the aromatherapy structure can be fully integrated into the structural components of the heater itself, which helps to make the overall structure more compact.

[0073] In some embodiments, the aforementioned air outlet assembly further includes a mesh cover 5 that snaps onto the air outlet side of the air outlet duct component 6. The area on the mesh cover 5 corresponding to the fragrance diffuser 11 also has a window opening 51. The lid can be removed and installed through the window opening 51 to facilitate repair or replacement of the lid.

[0074] It should be noted that the aforementioned air outlet duct component 6 can also be referred to as a mesh cover bracket in some situations.

[0075] In some implementations, such as Figure 9 As shown, the aforementioned air outlet duct component 6 can be annular, and the number of the aforementioned air outlets 61 can be two or more, arranged sequentially along the circumference of the air outlet duct component 6. The various air outlets 61 can cooperate to form a near-annular air outlet structure. The heater has a heating element 14, which can be annular, and the heating element 14, in conjunction with the air outlet duct component 6, achieves annular air outlet.

[0076] like Figure 12-13 As shown, the aforementioned mesh cover 5 and the air outlet duct component 6 can be snapped together for secure fixation. The mesh cover 5 is also annular, with snaps such as flange buckles 52 on both its outer and inner rings. The outer ring of the air outlet duct component 6 has a groove 63 for engaging with the flange buckle 52, and the inner ring of the air outlet duct component 6 has a protrusion 62 for engaging with the flange buckle 52. The mesh cover 5 can be securely fixed by bending the flange buckle 52 and snapping it onto the pre-set protrusion 62 and groove 63 of the air outlet duct component 6.

[0077] The aforementioned heater also includes an infrared receiver for receiving infrared commands from a remote control. The air outlet assembly further includes an infrared receiving window 8, which is mounted on the air outlet duct component 6. The air outlet duct component 6 has a mounting groove into which the infrared receiving window 8 can be installed with an interference fit. The infrared receiving window 8 corresponds to the signal receiving end of the infrared receiver. Infrared signals can pass through the infrared receiving window 8 and be received by the signal receiving end of the infrared receiver. In a specific application example, the infrared receiving window 8 can be a transparent ABS injection molded part, located close to the display panel and main board. The main function of the infrared receiving window is to ensure that the signal received by the entire unit from the remote control can pass through the receiving window, enhancing the infrared reception performance of the entire unit.

[0078] The air outlet assembly is a pre-installed, integrated unit. The mesh cover 5, as the outermost structure of the product, features a fully perforated design. Warm air is guided by the air outlet duct component 6 and then blown to the user through the mesh cover 5. The mesh cover 5 has an opening 51, allowing the user to directly access the lid without disassembling the air outlet assembly. The lid is fitted into a receiving groove 121 directly above the air outlet duct component 6. This receiving groove 121 is used to hold the aforementioned aromatherapy carrier 2, such as an oil-absorbing cotton pad. The aforementioned aromatherapy substance is essential oil, which the oil-absorbing cotton pad can absorb. An aromatherapy substance addition hole 102 is provided in the center of the surface of the fragrance diffuser 11 for adding aromatherapy substances such as essential oil.

[0079] In some embodiments, the present invention also provides a heater that may include the aromatherapy structure of any of the above-described embodiments, or the air outlet component of any of the above-described embodiments.

[0080] In some implementations, the aforementioned heater can be a flame heater.

[0081] In some implementations, such as Figure 14 As shown, the heater is supported by the support structure 9. When the heater is supported on a horizontal surface by the support structure 9, the angle α between the center line of the air outlet 61 and the horizontal surface is 12° to 18°, preferably 15°.

[0082] In the example above, by making the angle α between the centerline of the air outlet 61 and the horizontal plane 12° to 18°, the air blown out by the heater is tilted upwards. Specifically, when the heater is working, hot air is blown out of the air outlet 61 at an elevation angle of 12° to 18°, forming a turbulent airflow with a diffusion angle. This airflow diffuses upwards after leaving the air outlet 61 for a short distance. Since the receiving groove 121 is located on the upper part of the air outlet side 17, the upwardly diffused airflow can directly cover the surface of the fragrance diffuser 11, transferring heat to the aromatherapy carrier 2 through forced convection. The fragrance diffuser 11 is located on the central axis of the hot air diffusion cone, and the hot air flowing over its surface is inevitable. It is not "directly facing" but "diffused coverage," which further enhances the aromatherapy diffusion effect.

[0083] In some implementations, such as Figure 14 As shown, the aforementioned support structure 9 may include a first leg 91, a second leg 92, and a third leg 93. The first leg 91, the second leg 92, and the third leg 93 have the same structure. The first leg 91 and the second leg 92 are arranged symmetrically. The third leg 93 is located above both the first leg 91 and the second leg 92, and the third leg 93 is connected to the body 10 of the heater via an adapter 7.

[0084] In the above example, since the first leg 91, the second leg 92, and the third leg 93 have the same structure, material types can be saved. Furthermore, by symmetrically arranging the first leg 91 and the second leg 92, and placing the third leg 93 above both the first leg 91 and the second leg 92, and connecting the third leg 93 to the body 10 of the heater via an adapter 7, the height of the adapter 7 is designed to facilitate the coordination of the first leg 91, the second leg 92, and the third leg 93, allowing the heater to tilt and discharge air at a set angle when supported on a horizontal surface by the support structure 9.

[0085] In some embodiments, both the first leg 91 and the second bracket are threadedly connected to the body 10 of the heater. The adapter 7 can be fixedly connected to the body 10 of the heater using threaded fasteners such as screws. The third leg 93 can be threadedly connected to the adapter 7.

[0086] In some implementations, such as Figure 15 As shown, the heater also includes a motor 16 and a fan blade 13. The fan blade 13 can be an axial flow fan blade, and the motor 16 can be a DC motor. The heater body 10 has a rear shell 15 with an air inlet 151, and a rear air duct inside the body 10. When the heater is started, the DC motor 16 drives the fan blade 13, drawing air in through the air inlet 151 of the rear shell 15. The air enters the rear air duct and is blown along it towards the air outlet 61 on the air outlet component 6. The heating element 14 is fixed at the air outlet 61, thus heating the cold air, which is then blown out from the arc-shaped air outlet 61. Finally, the air is tilted upwards by the mesh cover 5.

[0087] The aforementioned aromatherapy structure is precisely positioned above the air outlet duct component 6, and hot air from the air outlet 61 converges upwards, significantly increasing the temperature at the aromatherapy structure location. This hot air environment effectively promotes the thermal motion of essential oil molecules within aromatherapy substances such as essential oils, increasing the aromatherapy evaporation rate and optimizing the aromatherapy diffusion effect.

[0088] This invention innovates the placement of the aromatherapy structure on the heater. By positioning the receiving groove 121 for the aromatherapy carrier 2 on the upper part of the heater's air outlet side 17, the aromatherapy carrier 2 is located directly above each air outlet 61, rather than on the side or bottom as in traditional methods. This allows the heater's air temperature to directly heat the aromatherapy carrier 2, increasing the kinetic energy of the aromatherapy molecules and maximizing diffusion efficiency. Furthermore, by having the lid snap onto the body 12 of the aromatherapy box 1, the lid can be disassembled without tools, solving the problems of traditional methods requiring tools for disassembly and having many hard-to-clean areas. The fragrance diffuser 11 also features an aromatherapy substance addition hole 102, which allows for replacement of the aromatherapy carrier 2 without disassembling the entire unit. When the aromatherapy carrier 2 is an oil-absorbing elastic block, this invention also embeds a heat-sensitive element 3, such as a heat-sensitive elastic film (e.g., thermoplastic polyurethane material), into the oil-absorbing elastic block. This heat-sensitive element 3 expands and contracts as the temperature rises within a range of 30-50°C. When the heater is turned on, the temperature of the air outlet 61 rises (usually 35-55℃), and the heat-sensitive component 3 expands, increasing the contact area between the oil-absorbing elastic block (such as oil-absorbing cotton) and the hot air, automatically accelerating the release rate of aromatherapy molecules. When the temperature decreases (e.g., at low fan speed settings), the heat-sensitive component 3 contracts, reducing the contact area and automatically slowing down the release rate. This allows the heater's hot air temperature to adapt to the aromatherapy release mechanism, making the aromatherapy rate dynamically linked with the overall temperature system. The invention also includes a bimetallic component 4 installed at the bottom of the aromatherapy carrier 2, which senses the temperature of the fragrance dispersing section 11 and automatically adjusts the safe distance between the aromatherapy carrier 2 and the fragrance dispersing section 11—the higher the temperature, the larger the distance (to prevent burning); the lower the temperature, the smaller the distance (to maintain efficiency). Key parameters: the heat deformation temperature range of the bimetallic component 4 is 35℃~55℃ (matching the hot air temperature range of the heater), and the deformation is 0~1.5mm, thus achieving thermal expansion-based safe gap adjustment.

[0089] This invention solves the technical problems of low aromatherapy evaporation efficiency, inconvenient replacement, and poor safety caused by the unreasonable placement of aromatherapy structures in traditional heaters. This invention achieves convenient assembly and disassembly of the aromatherapy structure on the heater. Furthermore, by placing the receiving groove 121 for the aromatherapy carrier 2 directly above the air outlet 61 of the heater, the high-temperature environment at the air outlet 61 makes the aromatherapy molecules move more actively, thereby improving the evaporation efficiency and achieving a better fragrance diffusion effect.
