[The problem that the idea attempts to solve]

By the way, in this type of extraction device,
When connected to a drinking water container, drinking water always reaches the valve seat of the device body, and the area from the valve seat to the tip of the extraction nozzle is in communication with the outside air. Therefore, if drinking water is left for a while after being extracted, the area from the valve seat to the tip of the extraction nozzle is likely to become dirty, which is not sanitary. Therefore, it is necessary to clean this area from time to time, but since the valve body of the on-off valve is attached to this area, if you try to remove the area for cleaning, the drinking water in the container may leak out. It leaks out and its removal is impossible.
Therefore, in order to remove the part and properly clean it, it is necessary to extract all the drinking water from the container. In addition, in this type of extraction device, where the extraction nozzle is removably attached to the main body, only the extraction nozzle can be removed and cleaned properly; It is difficult to properly clean these areas.

Therefore, an object of the present invention is to provide an extraction device in which the flow of drinking water in a container is blocked by an on-off valve, and the part on the downstream side of the valve seat can be removed and the part can be accurately cleaned. Our goal is to provide the following.

The present invention provides an extraction device of the type described above, which includes a valve seat part in which the opening/closing valve is provided in the inner hole of the main body, and a seat part that contacts the valve seat part in a separable manner to interrupt the inner hole. a rod-shaped valve body disposed in an intermediate portion and passing through the valve seat portion; and a spring member that urges the valve body to elastically abut the seat portion against the valve seat portion; An extraction nozzle is detachably attached to the tip of the main body and slidable in the axial direction within the inner hole so that the inner end of the extraction nozzle faces the tip of the valve body, and the operation lever is It is rotatably assembled on the main body side and connected to the extraction nozzle, and the valve body is pushed by the sliding of the extraction nozzle by rotation of the operating lever, and the opening/closing valve is pushed open. It is something to do.

[Functions and effects of the idea]

According to this configuration, the opening/closing valve can be pushed open by operating the operating lever to extract a desired amount of drinking water from the container, and even if the extraction nozzle is removed from the main body, the opening/closing valve remains closed and the container remains closed. Prevent drinking water from flowing out. In addition, in such a configuration, the extraction nozzle forms almost all the parts of the main body on the downstream side of the valve seat, so if the extraction nozzle is removed and cleaned, the downstream side of the valve seat is likely to get dirty. All areas will be properly cleaned. Therefore, the extraction device according to the present invention is extremely hygienic.
