Description

[Technical Field]

[0001] The present disclosure relates to an aroma lamp. [Background technology]

[0002] Aroma pots that heat liquid aromatic materials such as aroma oils using a candle flame have been commercially available. Aroma pots have a structure in which a candle is housed inside a translucent housing, and a container containing the aromatic material is placed above the candle. When the candle is lit, the aromatic material is heated by the candle flame. This causes the aromatic material to vaporize and diffuse its scent. In addition, the flickering flame of the candle flame can have a relaxing, refreshing effect on the user.

[0003] Since aroma pots require lighting a candle, users must prepare matches or a lighter, etc. Furthermore, users must use aroma pots with due care in handling fire.

[0004] Therefore, aroma lamps that house a large light bulb in a housing as a heat source to replace candles are available on the market. Aroma lamps are designed to heat aromatic materials using the heat generated when the light bulb is lit (see Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 11-283439 Summary of the Invention [Problem to be solved by the invention]

[0006] However, like conventional aroma lamps, even if a single large light bulb is housed in a housing and turned on, the light does not penetrate the entire housing, making it impossible to illuminate the entire lamp evenly and beautifully. This poses a problem in that the visual effect of the light cannot be fully conveyed to the user.

[0007] The present disclosure aims to provide an aroma lamp that can solve the above problems. [Means for solving the problem]

[0026] The aroma lamp of the present disclosure is configured to heat an aromatic material to diffuse the aroma and also to create a visual effect using light. The aroma lamp of the present disclosure allows the user to enjoy various aromas depending on the type of aromatic material, and the aroma effects can provide the user with various effects such as a relaxing effect and a refreshing effect. Furthermore, by allowing the user to enjoy both the aroma and the light at the same time, various effects such as a relaxing effect and a refreshing effect can be effectively provided to the user.

[0027] The aromatic material may be solid or liquid. Examples of aromatic liquids include essential oils and aroma oils. Solid aromatic materials include natural materials that exist in nature and emit fragrance, such as herbs, nuts, fragrant woods such as agarwood and sandalwood, wood chips made by finely chipping cypress, birch, cherry, and pine, tea leaves such as Japanese tea and black tea, and coffee beans, as well as materials impregnated with aromatic liquids such as essential oils and aroma oils extracted from natural materials such as plants, such as cloth, dried flowers, or porous materials. It is preferable to use natural materials as the aromatic material.

[0028] Aromatic liquids are refined by extracting aromatic components from natural materials, etc., but because some aromatic components are removed during the refining process, aromatic liquids and aromatic materials impregnated with aromatic liquids may not be able to diffuse the original scent of the natural materials. By using natural materials in aromatic materials, the aromatic components inherent in the natural materials can be diffused as they are, allowing users to enjoy the original scent of the natural materials. The aromatic materials are not particularly limited, but are preferably natural materials that emit fragrance at low temperatures, for example, about 60°C to 90°C, such as cinnamon, cardamom, and peppermint.

[0029] Hereinafter, an embodiment of an aroma lamp according to the present disclosure will be described with reference to the accompanying drawings.

[0030] 1 to 4 show an aroma lamp 1 according to one embodiment of the present disclosure. Aroma lamp 100 comprises an aroma unit 101 that diffuses a fragrance and a light-emitting unit 102 that diffuses light. Aroma unit 101 is located at the top of aroma lamp 100, and light-emitting unit 102 is located at the bottom of aroma lamp 100, with light-emitting unit 102 located below aroma unit 101. Aroma lamp 100 further comprises a handle 9 that is held by a user's hand when carrying aroma lamp 100.

[0031] <Explanation of the light-emitting part> 2 and 4, the aroma lamp 100 includes, as a light-emitting unit 102, a light source unit 5 and a lampshade 6 that encompasses the light source unit 5. The aroma lamp 100 is configured such that light is emitted from the light source unit 5 and passes through the lampshade 6, thereby diffusing the light into the external space.

[0032] The heavy lampshade 6 of the aroma lamp 100 is located at the bottom of the aroma lamp 100, and the center of gravity of the aroma lamp 100 is at the bottom. This reduces the burden on the user when they grasp the handle 9 and lift the aroma lamp 100, and also allows the aroma lamp 100 to be placed stably.

[0033] In addition, when a user carries the aroma lamp 100 by holding the handle 9, the handle 9 swings, and the heavy lampshade 6 is located at the bottom of the aroma lamp 100, so that the center of gravity of the aroma lamp 100 is at the bottom, preventing the container 1 placed on the installation part 3 from tilting. This prevents the aromatic material placed in the container 1 from spilling out of the container 1.

[0034] <Lampshade explanation> As shown in FIG. 10 , the lampshade 6 has the shape of a hollow, bottomed housing that can accommodate the light source unit 5 and the control unit 7 that controls the lighting operation of the light source unit 5. An opening is provided at the top of the lampshade 6 for inserting the light source unit 5 and the control unit 7 into the lampshade 6. The material of the lampshade 6 is not particularly limited as long as it is translucent and allows light to pass through. The lampshade 6 may be transparent or translucent, and may be colored, such as milky white or white, or may be colorless. The lampshade 6 can be made of, for example, glass, resin, ceramics, etc.

[0035] In the illustrated example, the lampshade 6 has a bottle shape and is composed of a cylindrical body 60 with a bottom that can accommodate the light source unit 5, the control unit 7, etc., and a cylindrical neck 61 that is integrally formed with the body 60. The body 60 forms the lower part of the lampshade 6, and the neck 61 forms the upper part of the lampshade 6. The neck 61 is formed to be slightly smaller than the body 60. The neck 61 is formed with two recesses 62 that are recessed inward on both the inner and outer surfaces. The two recesses 62 extend along the circumferential direction of the neck 61 and are formed at positions that face each other in the circumferential direction of the neck 61.

[0036] <Explanation of the light source> 2, 4, and 9, the light source unit 5 includes a plurality of light emitters 50. The light emitters 50 are not particularly limited as long as they emit light under the control of the control unit 7, and may be LED lights using light-emitting diodes, incandescent bulbs, or the like. In the illustrated example, the light emitters 50 are small LED lights.

[0037] The plurality of light emitters 50 are attached to a cylindrical casing 51. The casing 51 has, for example, a cylindrical shape with a polygonal cross section, and a plurality of side surfaces 52 are connected in the circumferential direction of the casing 51. Each side surface 52 of the casing 51 extends from near the upper end to near the lower end of the body 60 of the lampshade 6, and a plurality of light emitters 50 are arranged in each side surface 52 at intervals in the vertical direction of the casing 51. In other words, the light source unit 5 has a structure in which a plurality of light emitters 50 are arranged at intervals in the vertical direction, and a plurality of rows of these light emitters 50 arranged in the vertical direction are arranged at intervals in the circumferential direction. This allows light to be diffused into the external space by passing through the entire lampshade 6, not just a portion of the lower or upper part of the lampshade 6. Furthermore, no shadows are formed between the lights emitted from the adjacent light emitters 50, and the center of the light of each light emitter 50 does not show through, and uniform light without spots is emitted from the plurality of light emitters 50, so the entire lampshade 6 can be illuminated beautifully.

[0038] The interval between adjacent light emitters 50 in the vertical direction is preferably 0.5 mm or more and 2.5 mm or less in order to make the entire lampshade 6 brightly illuminated.

[0039] The multiple light emitters 50 may all emit light of the same color, or may all emit light of different colors, or may be color-coded into predetermined groups, with some emitting light of the same color, some emitting light of another same color, and the rest emitting light of yet another same color.

[0040] For example, at least some of the multiple light emitters 50 are configured as first light emitters 50A, 50B that emit orange light. Note that orange light is light with a color temperature of, for example, 1800 K or more and 3000 K or less. This allows the multiple light emitters 50A, 50B to produce a light that resembles a candle flame.

[0041] 18, the row of light emitters 50 attached to each side surface portion 52 of the casing 5 includes at least one pair of first light emitters 50A, 50B in which two first light emitters 50A, 50B that emit orange light are adjacent to each other in the vertical direction. In the illustrated example, rows 1-6 of six light emitters 50 lined up in the circumferential direction include two, one, two, two, one, and two pairs of first light emitters 50A, 50B that are adjacent to each other in the vertical direction, respectively.

[0042] As shown in FIG. 19 , the first light emitters 50A and 50B are lit with a waveform that repeats a cycle in which the luminance gradually decreases from a maximum value to a minimum value and then gradually increases back to the maximum value. In a pair of first light emitters 50A and 50B, the first light emitters 50A and 50B are lit so that their lighting timing is shifted. The time by which the lighting timing is shifted between the first light emitter 50A and the other first light emitter 50B is not particularly limited. For example, the first light emitters 50A and 50B are lit so that when the luminance of one first light emitter 50A reaches its maximum value, the luminance of the other first light emitter 50B reaches its minimum value, and when the luminance of one first light emitter 50A reaches its minimum value, the luminance of the other first light emitter 50B reaches its maximum value. This allows the flickering of a candle flame to be expressed using multiple first light emitters 50A and 50B. The lighting cycle of the first light emitters 50A, 50B is not necessarily limited to a gentle wavy cycle as shown in Fig. 19, and may be such that the luminance temporarily increases as it decreases from the maximum value to the minimum value and then reaches the minimum value, or may be such that the luminance temporarily decreases as it increases again to the maximum value and then reaches the maximum value. Furthermore, the cycle may be changed as it is lit, or may return to the original cycle.

[0043] In order to more accurately reproduce the flickering of a candle flame using the multiple light emitters 50A, 50B, it is preferable that the rows of light emitters 50 attached to each side surface portion 52 of the casing 5 have the positions of the pairs of first light emitters 50A, 50B offset in the vertical direction between the rows of light emitters 50 adjacent to each other on both the left and right sides in the circumferential direction, as shown in Fig. 18. In the illustrated example, the multiple light emitters 50 include first light emitters 50A, 50B that emit orange light, as well as a second light emitter 50C that emits white light. Note that white light is light with a color temperature of 3000K or higher and 5000K or lower, for example.

[0044] The light emitters 50 adjacent to the second light emitter 50C in the upper and lower directions of the casing 51, as well as the light emitters 50 adjacent to the second light emitter 50C on both the left and right sides in the circumferential direction 51 of the casing, are designated as first light emitters 50A and 50B. As a result, in the row of light emitters 50 attached to each side portion 52 of the casing 5, the order of one first light emitter 50A, the other first light emitter 50B, and the second light emitter 50C is repeated in the vertical direction, but as one goes in the circumferential direction, the order of one first light emitter 50A, the other first light emitter 50B, and the second light emitter 50C is shifted by one in the vertical direction. For this reason, in the illustrated example, for one first light emitter 50A, the light emitter 50 adjacent on both the left and right sides in the up-down direction and the circumferential direction is the other first light emitter 50B or the second light emitter 50C, and for the other first light emitter 50B, the light emitter 50 adjacent on both the left and right sides in the up-down direction and the circumferential direction is one first light emitter 50A or the second light emitter 50C. In this state, by alternately lighting one adjacent first light emitter 50A and the other adjacent first light emitter 50B without lighting the second light emitter 50C, the flickering of a candle flame can be more reproducibly expressed.

[0045] When the first light emitters 50A and 50B are lit, the second light emitter 50C is not lit, thereby allowing the flickering of a candle flame to be expressed by the multiple first light emitters 50A and 50B. However, it is not necessary to keep the second light emitter 50C from lighting when the first light emitters 50A and 50B are lit, and the second light emitter 50C may be lit at the same time.

[0046] By turning on the second light emitter 50C, bright white light can be emitted to the surroundings, thereby brightening the area around the aroma lamp 100.

[0047] In the illustrated example, the first light-emitting bodies 50A and 50B emit orange light to reproduce the flickering of a candle flame, but the first light-emitting bodies 50A and 50B may emit light of a color other than orange (except white), and in that case, the first light-emitting bodies 50A and 50B can still create a visual effect by flickering light.

[0048] 1 to 4 and 7 to 9, the head 30 constituting the installation unit 3, which will be described later, is provided with a light-emitting switch 53 for setting the light emission amount of each light-emitting body 50. In the illustrated example, the light-emitting switch 53 is configured with a rotatable knob, and by rotating the knob, the user can turn each light-emitting body 50 on / off and adjust the brightness. The lighting operation of each light-emitting body 50 in response to the operation of the light-emitting switch 53 is controlled by the control unit 7.

[0049] For example, the light-emitting switch 53 can be used to turn each light-emitting body 50 on and off and adjust its brightness in the following lighting patterns: When the light-emitting switch 53 is operated (in the illustrated example, the light-emitting switch 53 is turned) with each light-emitting body 50 turned off, the first light-emitting bodies 50A and 50B are first turned on, and as the light-emitting switch 53 is operated (in the illustrated example, the light-emitting switch 53 is turned), the first light-emitting bodies 50A and 50B are turned on so that their brightness increases. When the light-emitting switch 53 is then operated further (in the illustrated example, the light-emitting switch 53 is turned a predetermined amount), the first light-emitting bodies 50A and 50B are turned on while the second light-emitting body 50C is turned on; and then, as the light-emitting switch 53 is further operated (in the illustrated example, the light-emitting switch 53 is turned a predetermined amount), the first light-emitting bodies 50A and 50B are gradually turned off while the second light-emitting body 50C is turned on so that its brightness increases.

[0050] <Explanation of the aromatic part> 1 to 5, aroma lamp 100 includes, as fragrance unit 101, container 1 containing a solid aromatic material, lid 2 detachably attached to container 1, installation unit 3 on which container 1 is detachably installed, and heater 4 that heats container 1 installed on installation unit 3 from below. Aroma lamp 100 is configured so that the aromatic material contained in container 1 and lid 2 is heated by heater 4 to emit a fragrance, and the fragrance passes through lid 2, diffusing the fragrance into the external space.

[0051] <Container description> 1 to 5, the container 1 is located at the top of the aroma lamp 100 and is exposed to the outside. This makes it easy to put aromatic material into the container 1 and to remove used aromatic material from the container 1.

[0052] In the illustrated example, the container 1 is removable from the installation section 3 of the aroma lamp 100, so that the container 1 can be removed from the aroma lamp 100 and placed within reach of the user. This allows the container 1 to be cleaned if it becomes dirty, facilitating maintenance. In addition, while the container 1 can be placed in the installation section 3 and the used aromatic material can be removed from the container 1, placing the container 1 within reach of the user makes tasks such as replacing the aromatic material even easier.

[0053] The container 1 is made of a material with good thermal conductivity. The container 1 is preferably made of a metal such as aluminum or copper. A metal container 1 has a glossy surface and a beautiful appearance, which can improve the design of an aroma lamp 100 equipped with a metal container 1. The container 1 can also be made of materials other than metal, such as heat-resistant resin, ceramics, pottery, or stoneware.

[0054] 11 to 15, the container 1 comprises a bottom portion 10 on which the aromatic material is placed, a peripheral portion 11 rising from the outer periphery of the bottom portion 10, a flange portion 12 protruding outward from the upper edge of the peripheral portion 11, and a surrounding wall portion 13 rising from the outer periphery of the flange portion 12. The container 1 has a circular shape in a plan view, but the shape of the container 1 can be variously formed to match the shape of the installation portion 3, which will be described later.

[0055] The bottom portion 10 is plate-shaped with flat upper and lower surfaces. A solid aromatic material is placed on the upper surface of the bottom portion 10. When the container 1 is placed on the placement portion 3, the bottom portion 10 is placed on a heater plate 40 constituting the heater 4 described below, and the lower surface of the bottom portion 10 contacts the upper surface of the heater plate 40 (see FIG. 5). Because the lower surface of the bottom portion 10 is flat and a large contact area with the heater plate 40 can be secured, the aromatic material placed on the bottom portion 10 can be efficiently heated by the heater plate 40.

[0056] The peripheral portion 11 has a wall shape that is perpendicular to the bottom portion 10 or that slopes outward. The peripheral portion 11 surrounds the fragrance material placed on the bottom portion 10 and holds it on the bottom portion 10.

[0057] The flange portion 12 is plate-shaped with a flat bottom surface and a curved top surface. When the container 1 is placed on the installation unit 3, the flange portion 12 is placed on a support portion 33 located around the heater plate 40 in the installation unit 3, which will be described later, and the bottom surface of the flange portion 12 contacts the top surface of the support portion 33 (see FIG. 5).

[0058] The upper surface of the flange portion 12 is composed of an inner inclined surface 120 that slopes upward relative to the horizontal direction and an outer horizontal surface 121. When the lid 2 is attached to the container 1, legs 21 that form the outer peripheral edge of the lid 2, which will be described later, are placed on the horizontal surface 121 of the flange portion 12 (see FIG. 13 ). When the lid 2 is attached to the container 1, it is placed on the flange portion 12 that surrounds the bottom surface 10 of the container 1. The bottom surface 10 of the container 1 is the part that is heated by the heater 4, but when the lid 2 is placed on the bottom surface 10, heat applied to the bottom surface 10 is easily conducted to the lid 2, and the heat is easily dissipated from the bottom surface 10. This reduces the heating efficiency of the aromatic material placed on the bottom surface 10. By placing the lid 2 on the flange portion 12 that surrounds the bottom surface 10 of the container 1, it is possible to prevent heat applied to the bottom surface 10 from dissipating to the lid 2. This allows efficient heating of the aromatic material placed on the bottom surface portion 10. In addition, the natural material does not smell burnt due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0059] The surrounding wall 13 has a wall shape that is perpendicular to the horizontal surface 121 of the flange 12. When the lid 2 is attached to the container 1, the surrounding wall 13 surrounds the lid 2 placed on the horizontal surface 121 of the flange 12 and holds it on the flange 12 (see FIG. 13). This allows the lid 2 to be placed stably on the container 1.

[0060] The container 1 is provided with a handle 14 that the user can grasp with their hand when carrying the container 1, such as when placing the container 1 on the installation unit 3 or removing the container 1 from the installation unit 3. The handle 14 is formed so as to protrude upward from the container 1. The handle 14 can be formed, for example, in a "U" shape or a "C" shape, and can be formed integrally with the container 1 by fixing both ends to the container 1 by welding or the like.

[0061] The handle 14 can be formed on the bottom 10, flange 12, or surrounding wall 13 of the container 1, but is preferably formed on the flange 12 or surrounding wall 13 that is farthest from the bottom 10, and more preferably on the surrounding wall 13 that is farthest from the bottom 10. In the illustrated example, both ends of the handle 14 are fixed to the upper surface of the surrounding wall 13 of the container 1. The bottom 10 of the container 1 is the part that is heated by the heater 4, but if the handle 14 is formed on the bottom 10, heat applied to the bottom 10 will be easily conducted to the handle 14, and the heat will easily escape from the bottom 10. This reduces the heating efficiency of the aromatic material placed on the bottom 10. For example, compared to heating an aromatic material with a candle flame, heating an aromatic material with heater plate 40 requires that the aromatic material be heated at a relatively low temperature (approximately 60°C to 90°C), and therefore the heat applied to bottom portion 10 must be efficiently transferred to the aromatic material. As shown in the illustrated example, by forming handle 14 on a part of container 1 away from bottom portion 10, it is possible to prevent the heat applied to bottom portion 10 from escaping to handle 14, and the aromatic material placed on bottom portion 10 can be efficiently heated. In addition, low-temperature heating prevents the natural material from developing a burnt smell, and the fragrance can be continuously released while maintaining its strength.

[0062] <Explanation of the lid> As shown in Figures 1 to 5 and 11 to 13, the lid 2 is removably attached to the container 1. When the lid 2 is attached to the container 1, it covers the aromatic material on the bottom surface 10 of the container 1. This traps heat applied to the bottom surface 10 of the container 1 in the space between the container 1 and the lid 2, making it less likely to escape to the outside space, thereby efficiently heating the aromatic material placed on the bottom surface 10. In the illustrated example, the lid 2 is attached to the container 1 simply by placing it over the container 1, and is removed from the container 1 simply by lifting it up from the container 1.

[0063] The lid 2 is preferably made of metal like the container 1, which improves the design of the aroma lamp 100. The lid 2 can also be made of materials other than metal, such as heat-resistant resin, ceramics, earthenware, or stoneware.

[0064] As shown in Figures 11 to 13 and Figures 16 to 17, the lid 2 includes a top surface 20 and legs 21 formed on the outer periphery of the top surface 20. The top surface 20 has a circular plate shape in a plan view. One or more diffusion holes 22 are formed in the top surface 20. The diffusion holes 22 are through-holes that penetrate the top surface 20 in the thickness direction and serve to widely disperse the scent diffused by heating the aromatic material into the external space. It is preferable that the top surface 20 has multiple small diffusion holes 22 formed uniformly scattered over a wide area. This prevents heat applied to the bottom surface 10 of the container 1 from escaping to the external space through the diffusion holes 22, while facilitating the transmission of the scent emitted from the aromatic material to the external space through the diffusion holes 22.

[0065] In a vertical cross section, the top surface 20 has a shape that rises higher at the center than at the outer periphery. In the illustrated example, the top surface 20 is curved in an upwardly convex dome shape, and when the lid 2 is attached to the container 1, the center of the lid 2 in a plan view becomes the part that is farthest from the bottom surface 10 of the container 1.

[0066] The top surface 20 is provided with a handle 23 that the user can grasp with their hand when carrying the lid 2, such as when attaching the lid 2 to the container 1 or removing the lid 2 from the container 1. The handle 23 is formed to protrude upward from the top surface 20. The handle 23 can be formed, for example, in a "U" shape or a "C" shape, and can be formed integrally with the lid 2 by fixing both ends to the top surface 20 by welding or the like.

[0067] The handle 23 can be formed at any part of the top surface 20, but is preferably formed at the center of the top surface 20, which is the highest point and farthest from the bottom surface 10 of the container 1. The bottom surface 10 of the container 1 is the part heated by the heater 4. If the handle 23 is formed on the lid 2 in a part close to the bottom surface 10 of the container 1, heat applied to the bottom surface 10 will be easily conducted to the handle 23 of the lid 2, and the heat will be more likely to escape from the bottom surface 10. This reduces the heating efficiency of the aromatic material placed on the bottom surface 10. As shown in the illustrated example, by forming the handle 23 on the lid 2 in a part farthest from the bottom surface 10 of the container 1, the heat applied to the bottom surface 10 can be prevented from escaping to the handle 23 of the lid 2, allowing the aromatic material placed on the bottom surface 10 to be efficiently heated. In addition, the natural material will not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0068] The top surface portion 20 is not limited to the curved plate shape described above, and may be, for example, a flat plate shape.

[0069] The legs 21 are annular protrusions with a predetermined width that hang down from the outer periphery of the top surface 20. The lower surfaces of the legs 21 are flat. The lid 2 is attached to the container 1 by placing the legs 21, which form the outer periphery, on the container 1.

[0070] <Explanation of the first protrusion> As shown in Figures 12 to 13 and Figures 16 to 17, at least one protrusion 24 (hereinafter referred to as "first protrusion 24") facing vertically is provided on the leg 21 of the lid 2 or on the flange 12 of the container 1, which is the portion on which the leg 21 of the lid 2 is placed. A protrusion facing vertically means that the protrusion extends in the up-down direction perpendicular to a horizontal plane. In the illustrated example, the first protrusion 24 is formed on the underside of the leg 21 of the lid 2 so as to protrude downward. Note that when the first protrusion 24 is provided on the flange 12 of the container 1, the first protrusion 24 is formed on the horizontal plane 121 outside the flange 12 so as to protrude upward.

[0071] Preferably, three or more first protrusions 24 are formed on the underside of the leg portion 21 of the lid 2 or on the outer horizontal surface 121 of the flange portion 12 of the container 1, and more preferably, the three or more first protrusions 24 are formed at uniform intervals in the circumferential direction. This allows the lid 2 to be stably placed on the container 1. When the lid 2 is placed on the container 1, the first protrusions 24 are interposed between the leg portion 21 of the lid 2 and the flange portion 12 of the container 1, preventing the underside of the leg portion 21 and the outer horizontal surface 121 of the flange portion 12 from coming into surface-to-surface contact. This prevents heat applied to the bottom surface 10 of the container 1 from escaping from the flange portion 12, which contacts the lid 2 on the container 1, to the lid 2, thereby efficiently heating the aromatic material placed on the bottom surface 10. In addition, the natural material does not develop a burnt odor due to low-temperature heating, and the fragrance is continuously released while maintaining its strength.

[0072] <Explanation of the second protrusion> The lid 2 is attached to the container 1 by placing the legs 21 forming the outer peripheral edge on the container 1, and as shown in Figures 11 to 14, the legs 21 of the lid 2 or the surrounding wall 13 of the container 1 that surrounds the legs 21 of the lid 2 are provided with at least one protrusion 15 (hereinafter referred to as "second protrusion 15") that faces horizontally. A protrusion facing horizontally means that the protrusion extends in a direction parallel to the horizontal plane. In the illustrated example, the second protrusion 15 is formed on the inner surface of the surrounding wall 13 of the container 1 so as to protrude inward. Note that when the second protrusion 15 is provided on the legs 21 of the lid 2, the second protrusion 15 is formed on the outer surface of the legs 21 so as to protrude outward.

[0073] Preferably, two or more second protrusions 15 are formed on the outer surface of the leg portion 21 of the lid 2 or the inner surface of the surrounding wall portion 13 of the container 1, and more preferably, the two or more second protrusions 15 are formed at uniform intervals in the circumferential direction. This allows the lid 2 to be stably placed on the container 1. When the lid 2 is placed on the container 1, the second protrusions 15 are interposed between the leg portion 21 of the lid 2 and the surrounding wall portion 13 of the container 1, preventing the outer surface of the leg portion 21 from coming into surface contact with the inner surface of the surrounding wall portion 13. This prevents heat applied to the bottom portion 10 of the container 1 from escaping from the surrounding wall portion 13 that contacts the lid 2 to the lid 2, allowing the aromatic material placed on the bottom portion 10 to be efficiently heated. In addition, the natural material does not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0074] <Installation section description> As shown in Figures 1 to 5 and 7 to 9, the container 1 is detachably mounted on the mounting part 3. The aroma lamp 100 includes, as the mounting part 3, a head 30 attached to a neck part 61 forming the upper part of the lampshade 6. The head 30 is not particularly limited, but is preferably made of a material that is thermally insulating and has lower thermal conductivity than the metal that is the material of the container 1 and the lid 2. The head 30 can be made of, for example, a synthetic resin, but can also be made of materials other than synthetic resin, such as ceramics, pottery, or wood.

[0075] As shown in Figures 5, 7, and 8, the head 30 comprises a top surface 31 with an opening formed in the center, and a cylindrical peripheral surface 34 hanging down from the outer periphery of the top surface 31. A heater plate 40 constituting the heater 4 is disposed in the central opening of the top surface 31. The head 30 has a circular shape in a plan view, but the shape of the head 30 is not particularly limited and can be various shapes. The central opening of the top surface 31 has a circular shape in a plan view, but the shape of the opening is not particularly limited and can be various shapes.

[0076] The top surface portion 31 is annular and plate-shaped with a predetermined width. The top surface portion 31 includes a base portion 32 on the outer periphery side and a support portion 33 on the central opening side. The upper surface of the base portion 32 is located higher than the upper surface of the support portion 33, and the boundary between the base portion 32 and the support portion 33 is stepped. The support portion 33 is located around the heater plate 40. In the illustrated example, the lower surface of the bottom portion 10 of the container 1 contacts the upper surface of the heater plate 40, and the flange portion 12 of the container 1 is placed on the support portion 33 of the head 30, thereby installing the container 1 on the head 30, which constitutes the installation portion 3. The flange portion 12 and surrounding wall portion 13 of the container 1 fit inside the base portion 32 of the top surface portion 31, allowing the container 1 to be stably installed on the head 30, which constitutes the installation portion 3. Furthermore, because the head 30 forming the mounting portion 3 has thermal insulation properties, it is possible to prevent heat applied to the bottom portion 10 of the container 1 from escaping from the flange portion 12 to the mounting portion 3. This allows for efficient heating of the aromatic material placed on the bottom portion 10. In addition, the natural material does not develop a burnt smell due to low-temperature heating, and the fragrance can be continuously released while maintaining its strength.

[0077] 6, the peripheral surface portion 34 has an upper portion 35A and a lower portion 35B, the inner surface of the lower portion 35B is positioned outward from the inner surface of the upper portion 35A, and the boundary between the upper portion 35A and the lower portion 35B is a step 36. In the illustrated example, the head 30 is attached to the lampshade 6 so that the upper end of the neck portion 61 of the lampshade 6 abuts against the step 36 of the peripheral surface portion 34 and the lower portion 35B of the peripheral surface portion 34 surrounds the neck portion 61 of the lampshade 6.

[0078] 6, mounting portions 37 are formed on the lower portion 35B of the peripheral surface portion 34 to attach fasteners 8 that fix the head 30 to the neck portion 61 of the lampshade 6. In the illustrated example, two mounting portions 37 are formed at positions facing each other in the circumferential direction of the neck portion 61.

[0079] <Fastener Description> 1 to 9, the fastener 8 is not particularly limited as long as it can secure the head 30 to the neck portion 61 of the lampshade 6. In the illustrated example, the fastener 8 is configured to secure the head 30 to the neck portion 61 of the lampshade 6 and to arrange the handle 9 rotatably around the head 30. As shown in FIG. 6, the fastener 8 includes a latch 80, a fixing member 81, a ring 82, a washer 83, and a cap 84. The handle 9 can be made of wood, for example, but can also be made of materials other than wood, such as metal, resin, ceramics, leather, etc.

[0080] The latch 80 includes a base 85 that is annular and plate-like and has a predetermined thickness, and a pair of opposing protrusions 86 that protrude from one surface of the base 85. The latch 80 is attached to the attachment portion 37 so that the base 85 is disposed inside the circumferential surface 34 of the head 30 and the pair of protrusions 86 extend outside the circumferential surface 34, passing through the circumferential surface 34.

[0081] The fixing device 81 may be a screw, a bolt, or the like, and in the illustrated example, a set screw is used. The fixing device 81 is fixed to the mounting part 37 by fitting into a screw hole 38 formed in the mounting part 37. The tip of the fixing device 81 penetrates the base 85 of the latch 80 and abuts against the recess 62 in the neck part 61 of the lampshade 6. The head 30 is fixed to the neck part 61 of the lampshade 6 by clamping and supporting the neck part 61 of the lampshade 6 from multiple directions with the multiple fixing devices 81 fixed to the mounting part 37.

[0082] In the illustrated example, the tips of the fasteners 8 abut against recesses 62 formed in the neck portion 61 of the lampshade 6, so that the head 30 can be stably fixed to the neck portion 61 of the lampshade 6 by the multiple fasteners 8.

[0083] The ring 82 is installed on the mounting part 37 so that a part of it fits inside the recess 39 formed in the outer surface of the neck part 61 of the lampshade 6 and a part of it protrudes outward from the recess 39. The washer 83 is placed on the end of the ring 82 that protrudes from the recess 39.

[0084] The cap 84 comprises a disk-shaped cover portion 87 having a predetermined thickness, and an annular wall portion 88 that protrudes from one side of the cover portion 87 at a position inward from the outer periphery. A female thread is formed on the inner surface of the annular wall portion 88, and by fitting with a male thread formed on the outer surface of a pair of protrusions 86 of the latch 80, the cap 84 is integrated with the latch 80. A step is provided on the outer surface of the annular wall portion 88 of the cap 84, and the ring 82 and the washer 83 are sandwiched between this step and a recess 39 formed on the outer surface of the neck portion 61 of the lampshade 6.

[0085] A gap is formed between the cover portion 87 of the cap 84 and the washer 83, and the handle 9 is attached to this gap. The handle 9 is strip-shaped with a predetermined thickness and is bent, for example, into a "U" or "C" shape. Through holes are formed at both ends of the handle 9, and the annular wall portion 88 of the cap 84 is inserted into these through holes. The handle 9 is then rotatably attached to the head 30 by being sandwiched between the washer 83 and the cover portion 87 of the cap 84. The handle 9 is rotatable so as to be able to move at least between a horizontally tilted state and a vertically erected state. When the handle 9 is rotated to be erected vertically, the handle 9 extends over the fragrance portion 101, i.e., the container 1 and the lid 2. A user can easily carry the aroma lamp 100 by grasping the top of the handle 9 with their hands. When a user carries the aroma lamp 100 by holding the handle 9, the handle 9 swings relative to the head 30, thereby preventing the container 1 placed on the head 30 from tilting and preventing the aromatic material placed in the container 1 from spilling out of the container 1.

[0086] The handle 9 is rotatably attached to the fastener 8 between the base end of the fastener 8 fixed to the head 30 (in the illustrated example, the cover portion 87 opposite the tip of the fastener 8) and the peripheral portion 34 of the head 30. Here, the head 30 is fixed to the neck portion 61 of the lampshade 6 by the multiple fasteners 8 penetrating the head 30 and the tip of each fastener 8 abutting against the neck portion 61 of the lampshade 6. Therefore, when a user holds the handle 9 and carries the aroma lamp 100, the head 30 can be prevented from coming off the lampshade 6.

[0087] <Heater Description> 5, 7, and 8, the heater 4 heats the bottom surface 10 of the container 1 placed on the placement section 3 from below. There are no particular limitations on the heater 4 as long as it can heat the bottom surface 10 of the container 1, but it is preferable to use a heater plate 40 in order to efficiently heat the bottom surface 10 of the container 1 at a low temperature. A conventionally known heater plate can be used as the heater plate 40, and the bottom surface 10 of the container 1 is placed on a heating plate 41 made of a metal such as aluminum.

[0088] The heater plate 40 is fixed to a holder 42. The holder 42 is fixed to at least one of the head 30 and a casing 51 fixed to the head portion 30 so that the heating platen 41 of the heater plate 40 faces the central opening in the top surface portion 31 of the head 30.

[0089] The head 30 is provided with a heating switch 43 for setting the amount of heat from the heater 4. In the illustrated example, the heating switch 43 is configured with a rotatable knob, and by rotating the knob, the user can turn the heater 4 on and off and adjust the volume. The heat generation operation of the heater 4 is controlled by the control unit 7.

[0090] <Explanation of the control section>

[0091] The control unit 7 shown in FIGS. 5 and 9 controls the lighting operation of the light source unit 5 and the heat generation operation of the heater 4. The control unit 7 is configured with one or more printed circuit boards including a control circuit that receives input signals from the switches 43 and 53 to control the amount of heat generated by the heater 4 and the amount of light emitted by each light emitter 50 of the light source, and a power circuit that receives commands from the control circuit and supplies electricity to the heater 4 and each light emitter 50. The control circuit is configured, for example, using a microcontroller, and a program for lighting each light emitter 50 in a predetermined pattern is written in the microcontroller. The control circuit is configured to light each light emitter 50 in a predetermined pattern in response to an input signal from the light-emitting switch 53. For example, as described above, the control unit 7 can control the lighting operation of the multiple light emitters 50 so that, in response to operation of the light-emitting switch 53, the brightness of the first light emitters 50A and 50B in an unlit state gradually increases, causing the first light emitters 50A and 50B to light up, and further operation of the light-emitting switch 53 causes the second light emitter 51 in an unlit state to light up. In addition, the control unit 7 can control the lighting operation of the multiple light-emitting bodies 50 so that the second light-emitting body 51 lights up while the first light-emitting bodies 50A and 50B remain lit, and as the light-emitting switch 53 is further operated, the first light-emitting bodies 50A and 50B gradually turn off, and the second light-emitting body 51 lights up while its brightness gradually increases.

[0092] The control unit 7 is fixed to a casing 51. As shown in Figures 3, 4 and 8, the head 30 is provided with a receptacle 70 to which an AC / DC adapter plug can be connected in order to supply operating power to the control unit 7 from an external power source, which is an AC power source. A battery that can be charged with operating power to be supplied to the control unit 7 is fixed to the casing 51.

[0093] <Actions and effects of aroma lamps> The aroma lamp 100 of this embodiment described above comprises a fragrance section 101 that diffuses fragrance and a light-emitting section 102 that diffuses light, the light-emitting section 102 comprising a light source section 5 and a lampshade 6 that encompasses the light source section 5, the light source section 5 comprising a cylindrical casing 51 and a plurality of light-emitting bodies 50 attached to the casing 51, the light-emitting bodies 50 being arranged in a plurality of rows spaced apart in the vertical direction of the casing 51, and the plurality of rows of light-emitting bodies 50 arranged in a plurality of rows in the vertical direction of the casing 51 being arranged in a plurality of rows spaced apart in the circumferential direction of the casing 51.

[0094] According to the aroma lamp 100 of this embodiment, the light source unit 5 has a structure in which a plurality of light emitters 50 are arranged at intervals in the vertical direction of the casing 51, and a plurality of rows of these vertically arranged light emitters 50 are arranged at intervals in the circumferential direction of the casing 51. This allows light to be diffused into the external space by passing through not only a portion of the lower or upper part of the lampshade 6 containing the light source unit 5, but also the entire lampshade 6. Furthermore, shadows are not formed between the light emitted from adjacent light emitters 50, and the center of the light of each light emitter 50 is not visible through the lampshade 6, and uniform light is emitted from the plurality of light emitters 50 without mottling. This allows the entire lampshade 6 to be illuminated beautifully, providing the user with a sufficient visual effect created by light.

[0095] Furthermore, the aroma lamp 100 of this embodiment is characterized in that the row of light emitters 50 includes at least one pair of first light emitters 50A, 50B in which two first light emitters 50A, 50B emitting light of a certain color are adjacent to each other in the vertical direction of the casing 51, and the first light emitters 50A, 50B are illuminated with a waveform that repeats a cycle in which the brightness gradually decreases from a maximum value to a minimum value and then gradually increases back to the maximum value, and the illumination operation is controlled so that the illumination timing of one first light emitter 50A and the other first light emitter 50B in the pair of first light emitters 50A, 50B is staggered.

[0096] According to the aroma lamp 100 of this embodiment, the plurality of first light emitters 50A, 50B can express the flickering of light, thereby enabling an effective light-based effect.

[0097] Furthermore, the aroma lamp 100 of this embodiment is characterized in that the positions of the pairs of first light-emitting bodies 50A, 50B in the vertical direction of the casing 51 are offset between the rows of light-emitting bodies 50 adjacent to each other on both the left and right sides of the casing 51 in the circumferential direction.

[0098] According to the aroma lamp 100 of this embodiment, the plurality of first light emitters 50A, 50B can effectively express the fluctuation of light, thereby enabling a more effective light-based effect.

[0099] Furthermore, the aroma lamp 100 of this embodiment is characterized in that the multiple light-emitting bodies 50 include first light-emitting bodies 50A, 50B and a second light-emitting body 50C that emits light of another color, and the light-emitting bodies 50 adjacent to the second light-emitting body 50C above and below the casing 51, as well as the light-emitting bodies 50 adjacent to the second light-emitting body 50C on both the left and right sides of the circumferential direction of the casing 51, are the first light-emitting bodies 50A, 50B.

[0100] According to the aroma lamp 100 of this embodiment, the plurality of first light emitters 50A, 50B can more effectively express the fluctuation of light, thereby enabling a more effective light-based effect.

[0101] The aroma lamp 100 of this embodiment is characterized in that the first light emitters 50A and 50B emit orange light.

[0102] The aroma lamp 100 of this embodiment can produce a candle flame-like light using the multiple light emitters 50A, 50B. Therefore, the flickering flame of the candle flame can provide a relaxing effect, a refreshing effect, and the like to the user.

[0103] The aroma lamp 100 of this embodiment is characterized in that the second light emitter 52C emits white light.

[0104] According to the aroma lamp 100 of this embodiment, by turning on the second light emitter 50C, bright white light can be emitted to the surroundings, and the area around the aroma lamp 100 can be brightened.

[0105] <Modified Aroma Lamp> Although one embodiment of the aroma lamp of the present disclosure has been described above, the aroma lamp of the present disclosure is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present disclosure.

[0106] For example, as a modified example, a known planar heater may be used as the heater 4 in place of the heater plate 40, as long as a large contact area with the underside of the bottom portion 10 of the container 1 can be ensured. Alternatively, a sheathed heater in which metal pipes are densely arranged may be used as the heater 4.

[0107] As another example of a modified example, the positions of the handle 14 of the container 1 and the handle 23 of the lid 2 can be changed as appropriate. The handle 14 of the container 1 may be formed to protrude upward from the bottom surface 10. In this case, the handle 14 of the container 1 may penetrate the top surface 20 of the lid 2 to integrate the lid 2 and the container 1, and the lid 2 may be configured to be able to move up and down along the handle 14 of the container 1, making the lid 2 detachable from the container 1. In this modified example, the lid 2 is integrated with the container 1, which reduces the risk of the lid 2 being lost.

[0108] As another example of a modified example, the first protrusion 24 may be provided on the container 1, and the second protrusion 15 may be provided on the lid 2. Alternatively, the first protrusion 24 may not be provided on the container 1 and the lid 2, and the second protrusion 15 may not be provided on the container 1 and the lid 2.

[0109] As a further modification, for example, the shape of the container 1 and the shape of the lid 2 can be changed as appropriate.

[0110] As another example, the storage section for storing the aromatic material does not need to be configured as a container 1 that is removable from the installation section 3, but may be formed integrally with the head 30 that constitutes the installation section 3.

[0111] Also, for example, as a modified example, the installation part 3 does not need to be configured by the head 30 attached to the lampshade 6, but can be modified as appropriate.

[0112] As another example, the aroma lamp 100 may have other functions in addition to the light emitting function and the fragrance function.

[0113] Furthermore, as a modified example, the color and arrangement of the light emitted by each light emitter 50 of the light source unit 5 of the aroma lamp 100 are not particularly limited, and can be appropriately modified in design. [Explanation of symbols]
