Description

Detailed Description of the Invention A. Object of the Invention (1) Field of Industrial Application The present invention is directed to sewage in an aquarium used for raising ornamental fish,
In particular, the present invention relates to a cleaning tool in a water tank capable of sucking up and discharging dirty water at the bottom.

(2) Conventional technology To raise appreciation fish such as goldfish and tropical fish in the aquarium, lay gravel and pebbles on the bottom of the aquarium, plant aquatic plants and place ornaments such as stones on it. It is common practice to enhance the decorative effect, but as the breeding time elapses, residual food, feces, dead leaves, etc. gradually precipitate and accumulate, and the water quality in the aquarium is deteriorated for viewing. There is the inconvenience of adversely affecting the raising of fish.

By the way, the water in the aquarium, especially the sewage at the bottom of the
In order to remove the deposits to the outside, conventionally, for example, an electric pump (see, for example, Japanese Utility Model Laid-Open No. 53-21995) is used for suction or scooping of sewage with a scoop or the like is used. However, in the former case, the manufacturing cost and running cost increase, and coarse dirt such as dead leaves is clogged in the valve in the pump, and it is easy to cause a failure such as seizure in the pump drive part. There is a problem that not only water cannot be removed efficiently but also labor is required and the efficiency is extremely low.

The present invention has been made in view of the above circumstances, and is also effective in preventing clogging of coarse filth while allowing sewage in a water tank to be easily and efficiently sucked and discharged, and the structure is extremely simple and low-cost. It is intended to provide a cleaning tool for an aquarium.

B. Configuration of the invention (1) Means for solving the problem The invention of claim (1) for achieving the above-mentioned object is an aquarium cleaning tool for sucking up dirty water in the aquarium by a siphon action and discharging it to the outside of the aquarium. There is a suction pipe having a length reaching from the outside of the water tank to the bottom surface inside the water tank and having an open tip, and the suction pipe having one end connected to the base of the suction pipe and the other end communicating with the suction pipe. The water guide pipe is formed to have a length such that the other end of the water guide pipe reaches below the water tank when the tip of the suction pipe faces the inner bottom of the water tank. The invention according to claim 2 is an in-tank cleaning tool for sucking up sewage in the aquarium by a siphon action and discharging it to the outside of the aquarium. It has a suction A pipe, a flexible water guide pipe having one end connected to the base of the suction pipe and communicating with the suction pipe, and the other end open; The one-way valve has a valve body which is openably and closably hinged in the suction pipe, and is configured to allow the flow of water only from the suction pipe to the conduit pipe. The water guiding pipe is formed to have such a length that the other end of the water guiding pipe reaches below the water tank when the tip of the suction pipe faces the bottom of the water tank. The invention is characterized in that, in addition to the features of the invention of claim 1 or 2, the suction pipe is composed of a transparent body, and the invention of claim 4 is the invention of claim 1, 2 or 3. In addition to the features, it is for removing coarse debris such as dead leaves in the suction pipe. A strainer is provided.

(2) Action In the invention of claim 1, the open end of the suction pipe is located below the water tank and the open end of the suction pipe is immersed below the water surface in the water tank. By repeating the operation of lifting relatively high above the water surface and the operation of submerging the open tip again, it is possible to easily cause a water flow from the suction pipe to the conduit pipe,
Due to the siphon action generated based on this water flow, the dirty water in the water tank can be continuously sucked and discharged to the outside of the water tank through the suction pipe and the water guide pipe. On the other hand, in the second aspect of the present invention, the open end of the water guiding pipe is located below the water tank, and at least the tip of the wicking pile in a substantially upright posture is immersed below the water surface in the water tank. The operation of rapidly pulling up the upper pipe (during this pulling operation, the one-way valve is closed and the inside of the suction pipe tends to have a negative pressure, and the water in the pipe is lifted above the water level in the water tank), and the operation of rapidly pushing it down (At the time of this pushing-down operation, the water in the lifted suction pipe rises in the pipe due to inertia and flows toward the water guiding pipe side with the one-way valve opened). The flow of water toward the water tank can be easily generated, and the siphon action generated based on this water flow continuously sucks the dirty water in the water tank to the outside of the water tank through the suction pipe and the conduit pipe. It can be discharged. Therefore, during the siphon action, the open tip of the suction pipe faces the gravel at the bottom of the water tank or enters the gravel, and the suction pipe is appropriately moved to deposit on the gravel or in the gravel. It is possible to efficiently suck up and discharge fine contaminants such as residual food and feces that are mixed together with sewage. In this case, since the tip of the suction pipe is open, the tip of the pipe can easily enter the deep portion of the gravel layer with low resistance.

Further, in the invention of claim 3, since the suction pipe is made of a transparent material, the suction state of the dirty water in the suction pipe can be easily confirmed from the outside.

Furthermore, in the invention of claim 4, coarse dirt such as dead leaves and pebbles mixed in the wastewater are adsorbed by the strainer in the suction pipe, so that the water guiding pipe is clogged or the one-way valve (particularly dependent on claim 2 is It is effective in preventing clogging (in the case). Incidentally, dead leaves and pebbles adsorbed on the strainer are squeezed in the middle of the flexible water pipe to reduce the amount of water passing therethrough, or the suction pipe is tilted appropriately to change the posture of the pebbles and the like in the pipe. By doing so, the return due to their own weight can be promoted.
