Abstract
The utility model relates to a water changing device for a fish tank. The water changing device for the fish tank comprises the fish tank and a flexible pipe. The flexible pipe is lapped on a side wall of the fish tank. A sleeve is installed at an end part of the flexible pipe outside the fish tank. A piston is slidingly installed in the sleeve. The water changing device provided by the utility model is simple in structure and low in cost. The sleeve is installed at the end part of the flexible pipe outside the fish tank. The piston is slidingly installed in the sleeve. The piston is twitched, so that dirty water enters into the flexible pipe when the water is needed to be changed. The piston is pulled out of the sleeve after a siphon is formed, so that the dirty water can flow out freely. The water changing device is quite convenient and clean.
Description
Technical field
The utility model relates to a kind of changing water in fish tank instrument, especially a kind of changing water in fish tank device.
Background technology
Fish jar is a kind of very common household articles, and water-filling in it is used for the cultivation of fish, because fish all will carry out metabolism every day, so the water in the fish jar is very easy dirty, this just must change, during operation, people are immersed an end of a flexible pipe below the water surface, and the other end of flexible pipe is contained in the mouth, then air-breathing, form siphon pipe after water enters flexible pipe, water flows out naturally, but holds easily air-breathing the time bad, very easily with in the addle suction inlet, unhygienic.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of changing water in fish tank device simple in structure, with low cost is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of changing water in fish tank device comprises fish jar and flexible pipe, and flexible pipe rides over a sidewall of fish jar, it is characterized in that: the hose end that is in the fish jar outside is installed a sleeve pipe, and a piston is slidingly installed in this sleeve pipe.
And the hose end that the aspect ratio of described sleeve pipe bottom is in fish jar inside is low.
Advantage of the present utility model and beneficial effect are:
The utility model is simple in structure, with low cost, and the hose end that is in the fish jar outside is installed a sleeve pipe, and a piston is slidingly installed in this sleeve pipe.When needs change water, twitch piston, make addle enter flexible pipe, behind the formation siphon pipe, piston to be extracted in sleeve pipe, addle flows out naturally, very convenient, health.
