Description

Faucet Valve {Valve for Faucet}

The present invention relates to a faucet on-off valve, and relates to a simple and compact faucet on-off valve for performing repeated opening and closing of the faucet by repeatedly pressing the button.

As a valve device for controlling the opening and closing of the tap as a final discharge port of the tap water, the tap is made of a lever 2 for controlling the valve on the faucet fixture 1 as shown in FIG.

The lever (2) is generally provided to perform the cold and hot water flow control in one lever (2), the discharge port of the faucet fixture body (1) is formed so that tapping is formed to be connected to other mechanisms.

On the other hand, in recent years there is a trend that the water-saving device for saving water based on such a faucet is installed.

This is due to the inconvenience of using the faucet lever.For example, assuming you wash your face at the sink, it is common to use soap after applying water to your hand or face. It is cumbersome to wash your face and wash again with water.

Therefore, most users wash the soap with soap while keeping the water running, and then wash in the running water, which causes the waste of water.

As another example, when washing dishes, it is more watery than washing the face, which makes it more reluctant to operate the faucet lever with detergent and food residue on the hand, and later wash the lever. This is due to the inconvenience that must be followed.

A water saving device for improving this is expected, but conventional water saving devices are not only inconvenient to use as water saving devices in public facilities where water waste is expected, but also have a problem that productivity is reduced due to a complicated structure.

In connection with the present invention, the water-saving wash basin valve (application number 20-2001-00001638) of the diaphragm structure forms a button 3 protruding from the faucet body 1 as shown in FIG. The water is discharged by pressing the button (3). Since the water is discharged only while the button 3 is pressed, the hand is not free at the time of washing, and the inconvenience of having to hold the button at the time of washing is followed.

Moreover, since various devices including diaphragms are added to facilitate the operation force of the button 3, the structure is complicated and it is difficult to expect effective productivity.

Similarly, a faucet using an object detection sensor is performed, but this is also nothing different from the above-described button-type faucet, and there is a concern that the complexity and reliability of the structure may be deteriorated by the addition of an electronic component such as a sensor.

Alternatively, a water-saving one-touch valve device (application number 20-2002-0027455) or a foot-valve drive water-saving device (application number 20-2000-0027657) provided with a fixed button is provided.

Among them, the water-saving one-touch valve device uses a gear-driven valve body using a ratchet in the housing as illustrated in FIG. 2B, so that the opening and closing operations are repeated every time a button is pressed to secure the freedom of the hand and the valve. It is to increase the convenience of opening and closing.

However, as shown in the figure, the complexity of parts and structures cannot be avoided, and since it is difficult to mount directly on existing faucets, it is not effective in terms of difficulty of installation and productivity, and a foot-valve-driven water saving device is also used. It is the same.

In addition, there was a self-closing valve that was performed, which is a button-type water-saving device to determine the outflow time of water by the time of returning by the rod with the operation of the button.

However, this is used for waste of water in public baths, and the outflow time of the water is not at the user's discretion, and it is inconvenient to use for washing and washing dishes, and the volume and productivity of the faucet body according to the complexity of the structure are increased. Not preferable in terms of

The present invention is to provide a simple and compact faucet open and close valve for performing repeated opening and closing of the faucet by repeatedly pressing the button.

The present invention for this purpose is to apply the push-button structure of the writing instrument as the opening and closing operation opening and the valve body is attached to the valve housing directly connected to the faucet so that the opening and closing is performed by the button, the valve body is opened by pressing To facilitate this, a small primary valve that performs primary depressurization is dually coupled to the base valve.
