Description

[Detailed Description of the Invention] Cartridge tanks attached to water tanks such as humidifiers have their water supply openings frequently opened and closed, and are required to have high sealing performance and dimensional accuracy. This made it difficult to clean the inside of the tank through the mouth. On the other hand, if a large-diameter hole for cleaning is provided separately from the water supply port, the handle that supports the tank must be placed away from the water supply port when the tank is turned over to supply water. This is inconvenient, and the large-diameter cleaning hole requires a large amount of force to tighten the lid.

The purpose of this invention is to obviate the above-mentioned inconvenience.

This invention provides a lid for a large-diameter opening at the bottom of a tank that is removably provided with a valve box for a valve that opens when placed in the water tank, and a handle for supporting the tank and a tightening bolt. It is equipped with a handle that also serves as a lever for use.

Next, the structure, operation, and effects of the present invention will be explained with reference to one embodiment of the present invention shown in the drawings.

In FIG. 1, 1 is a cartridge tank (hereinafter simply referred to as a tank), and 2 is a water tank incorporating a fog generating section, an air blowing section, and a control section. FIG. 2 is a diagram showing a state in which the tank 1 is placed on the water tank 2.

The water tank 2 includes a part on which the tank 1 is placed and a water reservoir part sunk lower than the part.

According to the present invention, a large-diameter opening 13 is provided on the bottom of the tank 1, and the lid 9, which is screwed into this opening in a watertight manner via a gasket 14, has a tightening lever, a support for the tank, and a lid 9. A handle 8 that also serves as a transportation device is integrally provided, and a water level adjustment valve 4 is provided in the center of the lid 9.
The cylindrical portion of the valve box 5 is easily attached and detached and is watertightly attached. Valve 4 is closed by spring 6,
When the tank 1 is placed on the water tank 2, it is pushed up by the protrusion 3 provided on the water tank 2 and opened. Therefore, when the water level A in the water tank 2 falls below the lower edge of the cylindrical part of the valve box 5, air rises inside the valve box 5, enters the tank 1 through the open valve 4, and enters the tank 1. The water replaces air and flows down into the water tank 2 to restore the water level.

To refill empty tank 1, open tank 1.
If the valve box 5 is removed from the water tank 2, turned over as shown in Fig. 3, and the valve box 5 is removed, an opening for water supply will be created as shown in Fig. 4. When water is supplied from the faucet 11 and the tank is filled with water, the valve box 5 is screwed into the opening and tightened. Since the valve 4 is closed by the spring 6 at this time, water will not leak when the tank 1 is turned over again and carried by the handle 10.

As the tank 1 is used for a long period of time, organic matter and dirt contained in the water become limescale and adhere to the inner walls, becoming dirty. In this case, when the lid 9 is turned and removed using the handle 8, the large-diameter opening 13 opens, making it easier to clean the inside.

As shown in FIG. 5, the handle 8 of the lid 9 has an arm longer than the diameter of the opening, so a large force is not required to close the lid 9. Further, if a claw receiving part 12 that supports the end of the handle 8 is provided on the bottom surface of the tank, the handle 8 can support the weight of a tank full of water, so that the tank can be handled safely.

To summarize the effects of the present invention, 1. Since the water supply port is provided in the lid 9, the handle 8 is close to the water supply port, making it easy to support the tank during water supply.

2. By removing the lid 9, the large diameter opening opens, making it easy to clean the inside of the tank.

3. By attaching the valve box 5 to the lid 9, only one opening is required for the tank, the structure is simple, and the above two effects can be achieved.
