BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic atomizer for atomizing a liquid by vibrating a vibrator incorporated in a main body.

[0002]

2. Description of the Related Art An ultrasonic atomizing apparatus is provided in a main body case, is opened upward, and has a vibrator at the bottom, a liquid tank attached to the opening of the water tank, and a detachable liquid tank. Equipped with a liquid tank cover that can be freely closed and a blower fan. And the atomized liquid is sent to the outside. In this type of ultrasonic atomizing apparatus, the liquid tank cover can be removed to facilitate cleaning, liquid filling, and the like. Normally, when the air passage cover, the upper cover of the main body and the like are mounted on the main body case, they are fixed by these covers or locked with a knob.

[0003]

Among the above-mentioned conventional ultrasonic atomizers, the one in which the liquid tank cover is fixed with an air passage cover or the like, requires the air passage cover to be removed every time the liquid tank cover is removed. It has to be opened, which is troublesome, and in each case, there is a possibility that liquid, dust and the like may enter the air passage, which is not preferable for sanitation. In addition, what locks the liquid tank cover by a method of locking and unlocking with a knob,
There is a problem that the knob requires force to operate, and when the hand is wet with water or the like, it is difficult to slide and lock.

[0004] If the cover is not securely mounted, there is a problem that the liquid in the liquid tank leaks out and the liquid enters the inside through the hole for attaching the dial, which is not preferable.

[0005] The present invention has been made in view of the above problems, and can easily attach and detach the liquid tank cover, and
It is an object of the present invention to provide an ultrasonic atomizer in which liquid, dust and the like do not enter the air passage, and liquid and the like do not enter the inside of the main body.

[0006]

An ultrasonic atomizing apparatus according to the present invention is provided in a main body case, is opened upward, and has a vibrator at the bottom, and a liquid tank attached to the opening of the water tank. And a liquid tank cover that detachably covers the liquid tank. A liquid tank cover fixing arm that is rotatable by a predetermined angle in the horizontal direction is provided near the water tank on the upper surface of the main body case. The liquid tank cover is fixed by the cover fixing arm.

In the ultrasonic atomizing apparatus of the present invention, when the liquid tank cover fixing arm is rotated to the position where it comes to the top of the liquid tank cover, the liquid tank cover is fixed by the liquid tank cover fixing arm. When the fixing arm is rotated in a direction away from the top of the liquid tank cover with a finger, the fixing of the liquid tank cover is released.

[0008] In the ultrasonic atomizing apparatus of the present invention, an operation section having a dial is provided on the upper surface of the main body case at a position different from the opening of the water tank, and a convex structure is provided on the main body case surface to which the dial is attached. It may be formed, and this convex structure may be covered with a dial.

Further, the inner cylindrical surface of the projection structure of the main body case and the dial may be joined by an O-ring.

Further, the operation section provided on the upper surface of the main body case may be inclined at an angle within 45 degrees.
