BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a so-called ultrasonic humidifier.

[0002]

2. Description of the Related Art Conventionally, a water tank of this type of ultrasonic humidifier is formed by closing a water supply port formed on the bottom surface of a container with a lid portion having a valve body. The ribs formed in the water tank open the valve body to supply the water in the water tank to the water tank. Since the container of this water tank is formed in a bottle shape with only the water supply port opened, the water tank normally reaches a position above the bottom surface of the lid at the water level, and the water level decreases to the water surface and the bottom surface of the lid. When a gap is formed between the two, air enters the water tank through the gap and the valve element, and the water in the water tank is supplied into the water tank as the air invades.

However, in this structure, water must be supplied to the water tank by removing the water tank and the lid portion, and there is a drawback that the water supply operation to the water tank is troublesome.

In order to solve this drawback, a water tank having a water supply port formed on the upper surface is disclosed in Japanese Utility Model Laid-Open No. 60-135544 (F2).
Proposed on 4F 6/12). In this configuration, since the atmospheric pressure is constantly applied to the water surface in the water tank, if the above-described configuration in which the valve element is always opened by the rib formed in the water tank is taken, the water level in the water tank reaches the predetermined water level. Nevertheless, all the water in the water tank is supplied to the aquarium.
Therefore, a float for detecting the water level in the water tank is provided, and when the water level in the water tank drops due to the float, the valve body is opened.

However, when the dust or the like that has entered the water tank is caught between the valve body and the lid body and the valve body is not completely closed, all the water in the water tank is supplied to the water tank. was there.

[0006] Therefore, the applicant of the present application filed on March 8, 1990 as Japanese Patent Application No. 2-223664, which covers the upper opening of the water tank at the water passage portion. However, in this structure, in order to prevent dust and the like from entering the water tank, it is necessary to make the eyes of the water passage portion fine. When the eyes are made small, water is supplied through the water passage portion into the water tank. At this time, if the water passage part is covered with water, the air in the water tank will not be exhausted to the outside, so the water will form a film on the water passage part, and water will not be smoothly supplied from the water passage part into the water tank. was there.
