DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] First, the schematic configuration of an aroma diffuser according to the present invention will be described with reference to FIGS.

[0014] The aroma diffuser 1 comprises a diffuser body 9 (see also FIG. 6 ) in which an oil storage bottle 5 is stored in a storage body, storage section, or storage recess 3 with a front opening and an air pump 7 is disposed on the back side of the storage body 3, a design panel 11 removably attached to the front side of the diffuser body 9, and a casing 15 with a wall mounting flange 13 at its front end that is removably attached to the diffuser body 9 so as to cover the rear side of the front side of the diffuser body 9, or the middle to rear side of the diffuser body 9, or the rear side of the diffuser body 9.

[0015] The decorative panel 11 has a magnet 17 on its back surface, and this magnet 17 is attached to the mounting plate 21, which is attached to the front side of the diffuser body 9 using an adhesive screw 19, thereby allowing the panel to be detachably attached to the diffuser body 9 (see also Figure 6).

[0016] When the design panel 11 is removed from the diffuser body 9 (see FIG. 4), the five oil containing bottles 5 are exposed, making it possible to check the remaining amount of aromatic oil and to remove the oil containing bottles 5.

[0017] A flange portion 25 is provided at the front end of the container 3 of the diffuser main body 9, except for the upper middle portion 23. The upper middle portion 23 of the front end is formed with outlet holes 27 for discharging or spraying the aromatic oils in the oil containing bottles 5, and an airflow indicator 29 and a timer display portion 31 are provided on the side of the flange portion 25, along with a power switch 33, an aroma selection switch 35, a discharge amount selection switch 37, a timer setting switch 39, and a switch 41 for the LED light emitter.

[0018] In addition, a thin indirect lighting LED light-emitting section 43 is provided on the front end side of the diffuser body 9 so as to extend around the entire circumference and be continuous with the flange portion 25 on the rear side of the flange portion 25. The indirect lighting LED light-emitting section 43 is equipped with LED light-emitting elements (see symbol 44, symbol 44 indicates the LED light-emitting elements or the arrangement position of the LED light-emitting elements) arranged in a row in the longitudinal direction and a thin, translucent LED cover 45 which covers the LED light-emitting elements.

[0019] The aroma diffuser 1 configured as above is attached by embedding the casing 15 into a wall 47 through mounting holes 48 formed in the wall 47 so that the wall mounting flange 13 abuts against the surface of the wall 47, as shown in Figure 5. The outlet holes 27 for discharging or spraying aroma oil are located inside the room or on the room side of the wall 47. The attachment is performed, for example, by fixing the wall mounting flange 13 to the wall 47 with mounting screws (not shown). The aroma diffuser 1 is attached to the wall 47 in the following order: first, embed the casing 15 into the wall 47 and fix it, then fit and fix the diffuser body 9 into the casing 15, and then attach the mounting plate 21 to the diffuser body 9, and then attach the design panel 11.

[0020] In the figure, reference numeral 49 denotes a passage or pull-out portion for the power cord.

[0021] Next, the internal structure of the aroma diffuser 1 will be described with reference to FIGS.

[0022] Within the housing 3 of the diffuser main body 9, five plastic adapter stays 51 are attached in a line in the width direction slightly above the oil storage bottles 5, and each adapter stay 51 is formed with, for example, a deformable holding claw 53. An aroma adapter 59 having an air supply hole 55 (see FIG. 9) and an air discharge hole 57 (see FIG. 2) is screwed and attached to each oil storage bottle 5, and the oil storage bottle 5 is placed and attached within the housing 3 by fitting the aroma adapter 59 into the adapter stay 51 and being held by the claw 53 (in FIG. 7, the two oil storage bottles 5 and the aroma adapter 59 are omitted in order to show the shape of the adapter stay 51). Note that the oil storage bottle 5 can be removed from or attached to the adapter stay 51 with the aroma adapter 59 attached, and the aroma adapter 59 can be rotated to be removed from or attached to the aroma adapter 59 while attached to the adapter stay 51.

[0023] A tube mounting part 61 is formed to protrude from the back surface of the adapter stay 51, and this tube mounting part 61 extends rearward through the bottom surface of the container 3. An air passage is formed penetrating the tube mounting part 61 to supply air into the air supply hole 55 of the aroma adapter 59.

[0024] Five pump mounting frames 63 corresponding to the respective adapter stays 51 are formed on the underside of the back surface of the housing 3 of the diffuser body 9, and an air pump 7 is disposed in each pump mounting frame 63. The air pump 7 is fixed to the back surface of the housing 3 by attaching a cover 65 to the pump mounting frame 63.

[0025] The air discharge portion 67 of each air pump 7 and the tube attachment portion 61 of the corresponding adapter stay 51 are connected by an air tube 69 .

[0026] In the drawing, reference numeral 71 denotes a power supply / control board, and 72 denotes a power supply terminal. The bottom of the container 3 of the diffuser body 9 is fixed to an attachment piece 73 extending downward from the upper surface of the casing 15.

[0027] The operation of the aroma diffuser 1 will be described with reference to FIG.

[0028] A known structure can be used as a mechanism for supplying air or compressed air through the air tube 69 into the air supply hole 55 of the aroma adapter 59 by operating the air pump 7 and discharging the air containing aromatic oil. For example, as shown in FIG. 9, an oil suction pipe 75 is provided in the aroma adapter 59 so as to extend to the lower side of the oil containing bottle 5. A passage 77 is also formed through which the supplied air passes at high speed, and the upper end of the oil suction pipe 75 is connected to the passage 77. When the air passes through the passage 77 at high speed, it sucks up the aromatic oil from the suction pipe 75 (arrow X). The air containing aromatic oil is discharged from the air discharge hole 57 (arrow Y) and pressurizes the aromatic oil in the oil containing bottle 5 (arrow Z), causing it to rise in the suction pipe 75.

[0029] The operation control mode of the aroma diffuser 1 will be described with reference to FIG.

[0030] Information from the aroma selection switch 35, the discharge volume selection switch 37, the timer setting switch 39 and the LED light-emitting unit switch 41 is input to a control unit 79 consisting of a CPU, ROM, RAM, etc., which are configured on the power supply / control board 71, and based on the input information, the control unit 79 controls the operation of the air pump 7, the illumination of the air volume indicator 29, the illumination of the timer display unit 31 and the illumination of the indirect lighting LED light-emitting unit 43.

[0031] First, when the power switch 33 is operated to turn the power ON, the control unit 79 operates the air pump 7 that was selected when the power was OFF in the mode that was selected when the power was OFF, causes the indirect lighting LED light-emitting unit 43 to emit light in a color corresponding to this air pump 7, and adjusts the emission of the air volume indicator 29 to correspond to the operating mode of the air pump 7.

[0032] The control unit 79 switches the air pump 7 to be operated each time the aroma selection switch 35 is operated. Switching of the air pump 7 to be operated is performed, for example, by shifting the air pump 7 to be operated from left to right in Fig. 4, and after the right-most air pump 7, it is switched to the left-most air pump 7. Each aroma-containing bottle 3 or air pump 7 is assigned a different color from the others out of blue, orange, white, green, and purple, and the control unit 79 causes the indirect lighting LED light-emitting unit 43 to emit light in the color that corresponds to the selected air pump 7 to be operated.

[0033] The air pump 7 operates intermittently by repeatedly stopping and starting. The control unit 79 adjusts the discharge volume by switching the combination of stop time and operation time each time the discharge volume selection switch 37 is operated. The combination of stop time and operation time is preset in five stages, and the discharge volume is switched so that the discharge volume increases, but after the stage with the highest discharge volume, it switches to the stage with the lowest discharge volume. The control unit 79 adjusts and displays the length or width of the light-emitting portion of the air volume indicator 29 to correspond to the selected discharge volume.

[0034] The control unit 79 sets the operation time to one hour by operating the timer setting switch 39 once, and to two hours by operating it twice, and after the operation time has elapsed, turns off the power to stop the operation of the air pump 7. The control unit 79 causes one of the timer display units 31 to emit light when the operation time is set to one hour, and causes both timer display units 31 to emit light when the operation time is set to two hours.

[0035] The control unit 79 switches the indirect lighting LED light-emitting unit 43 between emitting and not emitting light each time the LED light-emitting unit switch 41 is operated. If the indirect lighting LED light-emitting unit 43 was not emitting light when the power was OFF, the control unit 79 causes the indirect lighting LED light-emitting unit 43 to emit light for three seconds in the color corresponding to the air pump 7 that was selected when the power was OFF when the power was turned ON.

[0036] The power switch 33, the aroma selection switch 35, the discharge amount selection switch 37, the timer setting switch 39 and the LED light emitting unit switch 41 can be configured as, for example, a touch switch or a capacitance switch. [Explanation of symbols]
