Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water-filling cap for a sink sink.

[0002]

[Prior art]

 Conventional caps are simply flat circular and are configured to cover the trap drain, so unless people are constantly watching when filling the sink, water will overflow from the top edge of the sink and There was a risk of causing an accident in which the rooms on the lower floor were flooded. In addition, when the cap was removed from the drain port after filling with water, there was a problem that the hand had to be inserted to the bottom of the sink.

Further, conventionally, there has been a structure in which the mouth of the drainage pipe is exposed to the flank of the sink and overflows from there. However, the structure is complicated and expensive, there are many problems such as clogging in the pipe, and the water level cannot be adjusted.

[0004]

[Problems to be solved by the device]

 The present invention was made in order to solve the above-mentioned conventional problems, and the purpose thereof is to prevent water from overflowing from the sink to flood the floor or the like, and the structure is simple and inexpensive. In addition to being able to adjust the amount of water filling, it is also possible to provide a cap for water filling the sink sink that can be removed near the surface of the water only with a fingertip.

[0005]

[Means for Solving the Problems]

 The water-filling cap of the sink of the present invention comprises a conical cylindrical body that opens downward, a large-diameter opening at the lower end is provided with a fitting part that fits into the sink drain port, and a small-diameter opening at the upper end. Is composed of a cap body provided with a guide cylinder portion; and a movable cylinder body slidably fitted in the guide cylinder portion. Provide stopper flanges at the upper and lower ends of the movable cylinder to prevent it from coming off the guide cylinder.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a conical cap body which opens downward, a ring-shaped fitting portion 1a is provided at a large diameter opening at a lower end thereof, and a short cylindrical shape is provided at a small diameter opening at an upper end thereof. A guide tube portion 1b is provided.

The cap body 1 is not limited to the conical shape as long as it has a shape that can be stably installed by applying an appropriate water pressure from the outer surface thereof, and may be a pyramid, a polygonal pyramid, or the like. In short, any cylindrical cone that is open downward may be used.

The fitting portion 1a has a shape and size that fits into the trap drain of the sink sink. Since the normal trap opening is circular, the fitting portion 1a is circular even if the cap body 1 has a shape other than the conical shape. An elastic material such as a rubber material may be attached to the outer peripheral surface of the fitting portion 1a so as to be fitted in a watertight state with the trap drain opening when fitted.

The movable cylinder 2 is fitted in the guide cylinder 1b so as to be slidable in the vertical direction. The movable cylinder 2 has a length such that the upper end opening thereof is located near the upper end of the edge of the sink when the movable cylinder 2 is extended most upward (in the state of the phantom line in FIG. 2). Stopper flanges 2a and 2b are provided at the upper and lower ends of the movable cylinder 2.

Since the cap of the present embodiment is configured as described above, when using the cap, the fitting portion 1a is fitted into the drain port of the trap 4 of the sink 3 as shown in FIG.

In this state, when water is poured into the sink 3 from the faucet, the water is collected in the sink 3. When the water surface rises to the upper end opening of the movable cylinder 2, it flows into the movable cylinder 2 and is drained from the trap drain port, so that the water level does not rise any higher, so that it does not overflow from the sink 3. Absent.

In order to adjust the water depth, the movable tubular body 2 may be moved up and down to adjust the position of the upper end opening.

[0014]

[Effect of device]

 1) Even if the water level in the sink rises, the upper end opening of the movable cylinder serves as an overflow drainage outlet for reliable drainage, so there is no risk of water overflowing from the sink and flooding the floor. 2) Since it is composed of a conical cylindrical cap body and a movable cylindrical body, the structure is simple and can be provided at low cost. 3) The water level can be adjusted extremely simply by sliding the movable cylinder vertically. 4) It can be removed from the trap drain port by simply picking up the upper end of the movable cylinder, and there is no need to worry about getting your hands wet.
