And a discharge port 63 for discharging mist.

  The reflection chamber 61 is partitioned by a bottomed cylindrical lower casing 64 and a covered cylindrical upper casing 65. The lower casing 64 and the upper casing 65 are made of resin such as polypropylene. A flange portion 64 a is formed at the upper end portion of the lower casing 64, and a flange portion 65 a is formed at the lower end portion of the upper casing 65. The flange portions 64a and 65a are connected to each other via screws (not shown). Further, the flange portions 64 a and 65 a are ultrasonically welded to enhance the sealing performance of the reflection chamber 61. In addition, fixation of the collar parts 64a and 65a is not limited to ultrasonic welding, An adhesive agent etc. may be sufficient.

  An introduction port 62 is formed at the bottom of the lower casing 64. The introduction port 62 is formed at a position offset from the center of the bottom portion toward the outer peripheral edge. The introduction port 62 is partitioned by a cylindrical body extending downward. The cylinder is fitted into a mist outlet 35 at the top of the mist separation chamber 28. A discharge port 63 is formed at the top of the upper casing 65.

The concave groove 67 has a shape that meshes with the protrusion 66. Since the protrusion 66 and the groove 67 are engaged with each other, sound leakage from the connection surface between the lower casing 64 and the upper casing 65 is reduced. Furthermore, a second protrusion 68 having a triangular cross section is formed on the tip surface of the protrusion 66. The second protrusion 68 is pressed against the planar bottom surface portion of the concave groove 67, thereby improving adhesion and further reducing sound leakage.

  On the side of the ridge 66, a convex portion 66a (see FIGS. 8 and 9) protruding outward is formed. A concave portion 67a (see FIG. 9) is formed on the side of the concave groove 67 so as to be recessed outward. The concave portion 67a has a shape that meshes with the convex portion 66a. Positioning of the lower casing 64 and the upper casing 65 is achieved by engaging the convex portions 66a and the concave portions 67a.

  According to the aroma mist generator 1 having the above-described configuration, the noise from the aroma mist generator 20 is introduced into the reflection chamber 61 from the introduction port 62 together with the mist. Noise is efficiently reduced by reflecting and resonating with the inner wall of the reflection chamber 61.

  Here, since the discharge port 63 is formed at a position offset with respect to the central axis of the introduction port 62, the sound that enters the reflection chamber 61 from the introduction port 62 hits the inner wall of the reflection chamber 61 and is reflected. It becomes difficult to come out directly from the discharge port 63. That is, since the sound emitted from the discharge port 63 is a sound after being reduced by reflection and resonance, the sound volume emitted from the discharge port 63 is reduced, and the noise reduction effect can be enhanced.

  Moreover, in the aroma mist generator 1 which concerns on this invention, since the soundproof cover 43 is provided around the compressor 22, the motor sound of the compressor 22 can also be reduced. Furthermore, since the buffer material 50 is provided around the compressor 22, the motor noise can be further reduced. Therefore, the noise reduction effect in the aroma mist generator 1 as a whole can be further enhanced.

  As described above, the aroma mist generator 1 with reduced noise can be used without worrying about noise even when placed at bedtime. Moreover, since the aroma mist generator 1 which concerns on this embodiment is a rechargeable type, it can be used without using a power cord. Therefore, the place where the aroma mist generator 1 is used is not limited. Furthermore, since the two aroma mist generators 1 are set, it is possible to enjoy different aroma mists by day and night, for example, by changing the type of aroma oil.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not the meaning limited to the said embodiment, A design change is possible suitably in the range which does not deviate from the meaning of this invention. For example, the shape of the outer shell of the aroma mist generator 1 is an example, and is not limited to the above configuration.

  Moreover, the aroma mist generator 1 is not limited to one set with two bodies, but may be a single body. Furthermore, it is not limited to a rechargeable type, an electric wire may be connected to an outlet, and a battery type may be sufficient.

  Furthermore, in the said embodiment, although the soundproof cover 43 and the silencer 60 are comprised with resin, such as a polypropylene, it is not limited to this. For example, the soundproof cover 43 and the silencer 60 may be made of a material other than resin such as glass. In this case, the lower casing 64 and the upper casing 65 of the reflection chamber 61 are fixed not by ultrasonic welding but by using an adhesive or the like.
