Hereinafter, a method of assembling and installing the ultrasonic vibration apparatus of the present embodiment having the above-described configuration will be described.

The piezoelectric body 230 is inserted into the insertion groove 223 of the metal vibrator 220, and the top surface 233 of the piezoelectric body 230 is adhered to the bottom surface of the metal vibrator 220. In this case, the piezoelectric body 230 may be adhered to the metal vibrator 220 through an adhesive or the like.

Subsequently, the third protrusion 262 of the packing 260 is inserted into the groove 226 of the metal vibrator 220, and the metal vibrating body surrounds the outer circumferential surface of the metal vibrator 220 with the first protrusion 261. When the packing 260 is inserted into the 220, the assembly of the metal vibrator 220 and the packing 260 is completed.

In addition, the assembled metal vibrator 220 and the packing 260 are inserted into the fastening hole 117 so that the fitting protrusion 116 is fitted into the fitting groove 263, and then the fixing part 270 below the packing 260. ). The wire 300 installed on the lower surface 231 of the piezoelectric element 230 is drawn out through the first through hole 271 of the fixing part 270. As a result, the metal vibrator 220 is disposed above the fitting protrusion 116 and the fixing part 270 is disposed below the fitting protrusion 116.

As shown in FIG. 3, before fastening the bolt 250, the surface on which the fixing part 270 is formed is formed to have a height lower than that of the outer end of the bending part 273, so that the edge of the fixing part 270 is packed ( The center portion of the fixing part 270 is spaced apart from the packing 260 even if it touches 260. In this state, when the bolt 250 passes through the first fastening hole 224, the second fastening hole 265, and the third fastening hole 272 to fasten the bolt 250, the bolt 250 is bent. The site where the third fastening hole 272 is formed inside of 273 is pressed. Due to this, the fixing part 270 is elastically deformed so that the edge of the fixing part 270 presses the packing 260 and the inner side of the fixing part 270 exerts downward force on the bolt 250 by a force to be returned. Will be added. As a result, the thread of the bolt 250, the metal vibrator 220, the packing 260, and the fixing part 270 are closely attached to each other to prevent the bolt 250 from being loosened. Therefore, the ultrasonic vibrator 200 is firmly fixed to the bottom 112 by the fixing part 270, so that the vibration of the piezoelectric body 230 can be effectively transmitted.

In addition, when the fixing portion 270 is formed in a flat plate shape, the outer side of the portion where the bolt 250 is fastened in the fixing portion 270 is bent to effectively seal the packing 260 to the fitting protrusion 116. However, the fixing portion 270 of the present invention is prevented by the bending portion 273 is formed such that the packing 260 can be in close contact with the fitting protrusion 116.

Therefore, the packing 260 is further in close contact with the fitting protrusion 116 of the bottom 112 through the bolt 250 and the bent part 273, so that the ultrasonic vibrator 200 is fixed to the bottom 112.

As such, the ultrasonic vibrator is assembled and installed, so that the vibration of the piezoelectric body 230 can be more effectively transmitted, and the number of parts is reduced, thereby reducing the number of assembly operations, thereby reducing the assembly time.

In addition, as shown in FIG. 8, a washing basket 400 containing a bowl or fruit to be washed is inserted into a sink in which the ultrasonic vibration device 200 is installed. The washing basket 400 is formed in a mesh shape, and the legs 410 are formed to protrude from the bottom to be spaced apart from the bottom 112 of the sink. As such, the washing basket 400 is spaced apart from the bottom 112 of the sink, so that the vibration of the ultrasonic vibrator 200 may be more effectively transmitted, and the washing may be more effective.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications or variations of the present invention without departing from the spirit and scope of the invention described in the claims below Can be carried out.
