Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cartridge tank that can be detachably attached to equipment such as a humidifier or a kerosene stove.

[Technical background of the invention]

Conventionally, this type of cartridge tank has a valve case that also serves as a cap, which forms a liquid outlet and is equipped with a valve body that normally closes the liquid outlet, which is screwed into a liquid inlet formed in the tank body. When the tank body is supplied with liquid (water for a humidifier, oil for an kerosene stove), the tank body is installed so that the liquid inlet faces upward. In this state, the valve case is removed, liquid is injected from the opened liquid inlet, and the valve case is attached to the liquid inlet to close the liquid inlet. When installing the tank body in a device, place the tank body at a predetermined part of the device with the liquid inlet facing downward, and push up the valve body of the folding valve case by the push-up part of the device. As a result, the liquid outlet is opened, and the liquid inside is supplied from the liquid outlet to a predetermined liquid chamber.

[Problems with background technology]

However, with the above-mentioned conventional type, each time the liquid is supplied into the tank body, the valve case must be removed from the liquid inlet and the valve case must be reinstalled. There was also a risk of losing it.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to supply liquid into the tank body without having to take the trouble of attaching and detaching the valve case one by one, and at the same time, to avoid the risk of losing the valve case. We provide a cartridge tank that is totally free of charge.

[Summary of the idea]

In the present invention, a liquid inlet is formed in the tank body, a support cylinder having a liquid passage port is provided inside the liquid inlet, and a valve case has a liquid outlet between the support cylinder and the liquid inlet. is movably provided, and the valve case is provided with a valve body that normally closes the liquid outlet, and when the tank body is in a state where the liquid inlet faces downward, the liquid inlet is closed by the valve case. When the valve case is closed and facing upward, the valve case is moved inwardly of the tank body by the hydraulic pressure of the liquid supplied into the tank body or by its own weight, and the liquid inlet is opened. The present invention is characterized in that liquid can be supplied into the tank body while the valve case remains attached to the tank body.

[Example of idea]

An embodiment in which the present invention is applied to a cartridge tank of a humidifier will be described below with reference to the drawings.
First, since the humidifier shown in FIG. 1 is well known, its configuration will be briefly described. 1 is a main body case, 2 is an atomizing water tank, 3 is a tank mounting part, 4 is a push-up protrusion, and 5
is an ultrasonic transducer.

Reference numeral 6 denotes a cartridge tank which is detachably mounted on the tank mounting section 3, and will be described below with reference to FIGS. 1 to 3. First, in Figures 1 and 2, 7 is a rectangular tank body, with a handle 8 (Figure 1) formed in the upper part and a liquid inlet 9 (Figure 2) formed in the lower part. A substantially cylindrical mouth portion 10 is formed protruding from the outer surface of the peripheral edge of the liquid inlet 9, and a support cylinder 12 having a liquid passage port 11 is formed protruding from the inner surface of the peripheral edge. .
13 is a valve case, in which the flange 13a is connected to the support cylinder 1.
A relatively weak spring 14 is inserted into the liquid inlet 9 so as to be movable up and down. The spring 14 urges the valve case 13 in a direction in which the flange 13a always closes the liquid inlet 9, as shown in FIG. Reference numeral 15 denotes a liquid outlet cylindrically protruding from the valve case 13, and a support portion 16 is formed inside the liquid outlet 15. 17 is a bowl-shaped valve body having a valve stem 18;
6 is inserted into the liquid outlet 15 so that it can be opened and closed. 19 is a spring, this is valve stem 1
8 is wound around the spring seat 18a formed at the end of the valve stem 18 and the support portion 16,
The valve body 17 normally closes the liquid outlet 15 by receiving the spring force of the spring 19.

Now, FIG. 2 shows the case where the cartridge tank 6 is removed from the humidifier and the tank body 7 is placed in a state with the liquid inlet 9 facing downward.
When this is done, the valve case 13 receives not only the biasing force of the spring 14 but also the internal water pressure to close the liquid inlet 9, and in this state, the tank body 7 is inserted into the tank as shown in FIG. When placed on the placement section 3, the push-up protrusion 4 pushes up the valve stem 18 against the urging force of the spring 19 and the water pressure, thereby pushing the valve body 17 into the second position.
The liquid outlet 15 is raised as shown by the two-dot chain line in the figure.
, and supplies water to the atomizing water tank 2. On the other hand, when water is to be supplied into the tank body 7, the tank body 7 is placed in a state with the liquid inlet 9 facing upward as shown in FIG. 3, and water from a tap (not shown) is supplied to the spout 10. In this case, the water from the faucet flows into the valve case 1 due to its water pressure Wp.
3 against the biasing force of the spring 14 to open the liquid inlet 9, and open the liquid inlet 9 and the liquid passage port 1.
1 and is supplied into the tank body 7.

In the embodiment described above, the spring 14 is provided, and the valve case 13 is subjected to water pressure (hydraulic pressure) that resists the spring force of the spring 14.
However, the spring 14 may not be provided and the valve case 13 may be moved only by its own weight. Although the present invention has been described as being applied to a cartridge tank for a humidifier, the present invention can be widely applied to cartridge tanks for other equipment such as kerosene heaters.

[Effect of idea]

As is clear from the above description, the present invention includes a movable valve case having a liquid outlet formed in the liquid inlet formed in the tank body, and a valve that normally closes the liquid outlet in the valve case. of the liquid to be supplied into the tank body when the liquid inlet is closed by the valve case and the liquid inlet is directed upward when the tank body is in a state where the liquid inlet faces downward. This cartridge tank is characterized in that the valve case is moved by hydraulic pressure or its own weight to open the liquid inlet, and with this, the following effects can be obtained. That is, since the liquid inlet can be opened by moving the valve case while the valve case remains attached to the tank body, the valve case must be removed from the liquid inlet and then reattached in order to supply liquid into the tank body. Unlike conventional methods, which required a lot of trouble, there is no need for such troublesome work when supplying liquid into the tank body, and it is extremely easy to supply liquid into the tank body, and there is no need to worry about losing the valve case. Then there is no fear that it will happen.

[Brief explanation of drawings]

The drawings show one embodiment of the present invention.
Figure 1 is a vertical cross-sectional view of the entire humidifier, Figure 2 is an enlarged vertical cross-sectional view of the main parts of the tank body with the liquid inlet facing downward, and Figure 3 is a vertical cross-sectional view of the tank body with the liquid inlet facing downward. FIG. 3 is an enlarged vertical cross-sectional view of the main part when the device is in an upwardly facing state. In the figure, 6 is a cartridge tank, 7 is a tank body, 9 is a liquid inlet, 13 is a valve case, 15 is a liquid outlet, and 17 is a valve body.
