Abstract
The utility model discloses a water pumping device for a fishbowl, and belongs to living goods. The water pumping device comprises a hose and a piston, wherein the cylindrical piston is mounted in the hose, and contacted with an inner wall of the hose; a pulling rope hole is formed at each end of the piston; the pulling rope holes are connected with pulling ropes; and the other ends of the pulling ropes are connected with pull rings. The water pumping device for the fishbowl drives the piston to move by pulling the pull rings and pumps out water in the fishbowl; the water does not need to be sucked by a mouth; and the water pumping device is clean and convenient.
Description
Technical field
The utility model relates to a kind of pumping device that we use when giving changing water in fish tank, specifically a kind of fish jar pumping device.
Background technology
In family, the people that breeds fish knows, the water in fish jar is to need often to change, and one can increase the oxygen content in water, and can clear up the foreign material in fish jar, allows fish jar keep clean.When changing water, we generally use a pipe, and an end inserts in water, and the other end is inhaled with mouth, utilize siphon principle that the water in fish jar is released, when inhaling with mouth, dynamics is difficult to hold, the dynamics of inhaling is little, and water can't pump out, great efforts can be with in the addle suction inlet, very unhygienic.
The utility model content
The purpose of this utility model is to provide a kind of fish jar pumping device, and this fish jar pumping device can conveniently be extracted the water in fish jar out, facilitates us to changing water in fish tank.
The technical scheme in the invention for solving the technical problem is: a kind of fish jar pumping device, it is characterized in that, comprise flexible pipe and piston, in the inside of flexible pipe, one piston is installed, piston is cylindrical, and piston contacts with hose inner wall, and respectively there is a stay cord hole at the two ends of piston, stay cord is connected with stay cord on the hole, and the other end of stay cord is connected with draw ring.
The beneficial effects of the utility model are: this fish jar pumping device is released the water in fish jar by pulling draw ring to drive piston movement, needn't absorb water with mouth again, and is hygienic and convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 flexible pipe, 2 pistons, 3 stay cord holes, 4 stay cords, 5 draw rings.
Embodiment
As shown in Figure 1.A kind of fish jar pumping device, comprise flexible pipe 1 and piston 2, one piston 2 is installed in the inside of flexible pipe 1, piston 2 is cylindrical, piston 2 contacts with flexible pipe 1 inwall, and respectively there is a stay cord hole 3 at the two ends of piston 2, is connected with stay cord 4 on stay cord hole 3, the other end of stay cord 4 is connected with draw ring 5, and the design of draw ring 5 can conveniently pull with hand stay cord 4.
During use, only need first piston 2 to be moved to an end of flexible pipe 1, flexible pipe 1 is put into fish jar, grasp draw ring 5 and pull stay cord 4, stay cord 4 just can drive piston 2 motions, and piston 2 motions make the interior generation vacuum of flexible pipe 1, under the effect of atmospheric pressure, water in fish jar just enters in flexible pipe 1, just the water in fish jar can have been released.This fish jar pumping device simplicity of design, hygienic and convenient.
