Abstract

PURPOSE:To prevent invasion of water into a body through an air supplying cylinder if water is supplied into a water container with a water tank full of water by forming a capacity from an inner case bottom surface including the water container to a wind outlet of a wind blowing cylinder to be larger than that of the water tank. CONSTITUTION:A water tank 20 is supplied with water by pouring it from an opening on an upper surface. In this instance, if dirts and the like invade into the water tank 20 together with the water during this water supply and go between a lid 22 and a valve 24 to hinder a complete closing of the valve 24, it is possible that the water in the water tank 20 flows into the water container 5. In order to prevent this, an inner case 4 is formed to have a laterally sectioned area larger than that of the water container 5, a wind supplying cylinder 13 is extended upward from a bottom surface of the inner case 4, and a height from the bottom surface of the inner case 4 to a wind outlet of the wind supplying cylinder 13 is made to be sufficiently large, so that even if the water in the water tank 20 which is full of water entirely flows into the inner case 4, the water level does not reach the wind outlet of the wind supplying cylinder 13. That is, a capacity from the bottom surface of the inner case 4 to the wind outlet of the wind supplying cylinder 13 including the water container 5 is formed larger than that of the water tank 20.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to improvements in ultrasonic humidifiers.

(b) Conventional technology Conventionally, the water tank of this type of ultrasonic humidifier is formed by closing a water supply port formed on the bottom of a container with a lid body having a valve body. The water in the water tank was supplied into the water tank by opening the valve body using ribs formed on the water tank. The container of this water tank is shaped like a bottle with only the water supply opening open, so the water level of the tank normally reaches a position above the bottom of the lid.
When the water level decreases and a gap is formed between the water surface and the bottom of the lid, air enters the water tank through the gap and the valve body, and as the air enters, the water in the water tank flows into the tank. It is designed to be supplied internally.

However, in the second configuration, supplying water to the water tank requires removing the water tank and removing the lid, which has the drawback that the task of supplying water to the water tank is troublesome.

In order to solve this drawback, a water tank with a water supply port formed on the top surface was published in Japanese Utility Model Application Publication No. 135544/1984 (F2
4F6/12). In this configuration, atmospheric pressure is always applied to the water surface in the water tank, so if the above-mentioned configuration in which the valve body is constantly opened by the ribs formed in the water tank is used, the water level in the water tank will reach a predetermined water level. Despite this, all the water in the water tank ends up being supplied into the tank. Therefore, a float is installed to detect the water level in the aquarium.
The valve body is opened when the water level in the water tank decreases due to the float.

However, there are cases where dirt, etc. that has entered the water tank gets caught between the valve body and the lid, preventing the valve body from closing completely, and all the water in the water tank is supplied into the tank. If all the water in the water tank is supplied into the water tank when the tank is almost full, water will enter the main unit through the air outlet formed above the air cylinder, damaging the electrical components inside the main unit. was there.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and even when the water tank is full and all the water in the water tank is supplied, water still flows into the air blowing cylinder. An object of the present invention is to provide an ultrasonic humidifier that does not penetrate into the main body through the ultrasonic humidifier.

(d) Means for Solving the Problems The present invention comprises: an inner case having a water tank with an ultrasonic vibrator attached to the bottom; a main body housing the inner case and housing a blower; a blower tube body having a blower port that guides the air into the inner case;
Equipped with a top-opening water tank that supplies water to the aquarium by opening a valve element on the bottom when the water level in the aquarium drops, and the capacity of the water tank is smaller than the capacity up to the air outlet in the inner case. It is characterized by what it did.

(e) When the water in the working water tank runs out, water is produced from the top opening and is supplied into the water tank. etc. entered the water tank, and when the valve body closed, it got caught between the valve body and the water tank, and the valve body did not close completely, causing all the water in the water tank to flow out into the inner case. However, since the volume from the bottom of the inner case containing the water tank to the air outlet of the air cylinder body is larger than the volume of the water tank, even if all the water has flowed out from the water tank when it is full, the air will not be blown. The water in the inner case does not flow through the cylinder into the space surrounded by the main body and the inner case, and the electrical components placed in the space surrounded by the main body and the inner case are not damaged.
