Description

  The present invention relates to a decorative body placed in a water tank for appreciating fish, and more particularly to a decorative body suitably used to make sludge and garbage in the water tank inconspicuous.

Organic matter, such as fish excrement and residual food, pollutes the water and generates toxic ammonia, so it is necessary to clean it regularly when raising fish in an aquarium.
On the other hand, gravel is often laid on the bottom of the aquarium to enhance the appreciation effect and calm the fish.
Such gravel is difficult to separate from organic matter, so cleaning is extremely troublesome and may kill the breeder's willingness to keep it.
Therefore, instead of laying gravel, a decorative substrate having a large number of water passage holes penetrating in the vertical direction and integrally including artificial ornaments such as stone, sand, and rock on the upper surface is provided as the bottom surface of the aquarium. A technique has been proposed in which organic substances falling from the water holes are collected in the space (Patent Document 1). Furthermore, a configuration (Patent Document 2) in which a filtering material is accommodated in the space and a configuration (Patent Documents 3 and 4) in which the bottom surface of the water tank is inclined so that organic substances gather at one corner of the bottom surface have been proposed.

However, in the configuration described in Patent Document 1, in order to remove organic matter from the water tank, after lifting the decorative substrate, the organic matter spreading over the entire bottom surface is collected or sucked up, or the water above the decorative substrate is drained. It must be transferred to a separate container with the fish or discarded. In the former case, the organic matter eventually mixes with the water above the substrate. The latter is a cumbersome work like conventional gravel. In addition, the configuration described in Patent Document 2 is simply configured such that a filter medium is placed, and water is not filtered by the filter medium.
On the other hand, in the configurations described in Patent Documents 3 and 4, the bottom surface of the water tank must be formed in a considerably steep slope, or the organic substance must wait for a considerable long period of time, for example, several months, until it gathers at one corner of the bottom surface. The former is unrealistic because the total height of the aquarium becomes too high, and the latter eventually contaminates the water with minute organic matter that does not fall to the bottom.
Therefore, the subject of this invention is providing the aquarium decoration body which can remove easily the organic substance in an aquarium with a realistic structure.

In order to solve the problem, the aquarium decorative body of the present invention is
The floor member has a number of water holes, the upper surface is decorated to resemble a natural water bottom, and the lower surface is arranged to face the bottom surface of the aquarium with a space therebetween, near one corner of the aquarium A floor member having a collection chamber provided by partitioning a part of the interval;
And a stirrer for circulating water within the interval.
And the organic substance which moves with the water circulated by the stirrer can be recovered in the recovery chamber.

  According to this aquarium decorative body, organic matter such as excrement and residual bait falls to the bottom surface of the aquarium through the water passage holes of the floor member, so that the surface of the floor member is difficult to get dirty. Since the bottom of the aquarium is covered with a floor member, the fallen organic matter is difficult to see from the outside. And since the upper surface of the floor member is decorated to resemble the natural water bottom, the inside of the aquarium looks more beautiful than gravel without laying gravel.

  The fallen organic matter moves with the water by circulating the water with a stirrer, and is collected in the recovery chamber. Therefore, when the collection chamber is a cartridge type that can be attached to and detached from the floor member body, the collection chamber can be taken out and the organic matter can be discarded. When the collection chamber is provided integrally with the floor member, it can be opened and closed on the top surface. The organic matter can be easily removed by forming a simple outlet, opening the outlet and sucking it up with a pump or the like.

  The organic matter that has fallen to the bottom of the aquarium is difficult to see from the outside, so the aquarium needs less cleaning. The dropped organic matter is collected in the collection chamber, so that the organic matter can be easily removed and cleaning is easy.

It is a perspective view which shows the state which put the water tank decoration body of 1st embodiment in the water tank (an electric system storage box is omitted). It is also a front view (including an electrical system storage box). It is a disassembled perspective view which shows the said water tank decoration body. It is sectional drawing which shows the place cut | disconnected horizontally in the intermediate | middle height position of the water flow hole in a floor member, and a recessed part bottom surface in the state which put the water tank decoration body of FIG. 1 in the water tank. It is a horizontal sectional view of the second aquarium decorative body.

Embodiment 1
1-4, the aquarium decorative body 1 according to the first embodiment is a decorative body laid on a flat bottom in a rectangular parallelepiped-shaped aquarium 10, and is made of resin and is a plan view of the aquarium 10. A floor member 2, a rock member 3, an impeller 4, and a filter 5, each having a rectangular shape complementary to the inner periphery, are provided. An electric system storage box 6 is placed on the upper end surface of the water tank 10.

  The floor member 2 has a large number of water passage holes 21 having a diameter of about several millimeters to 20 mm, the upper surface is decorated to resemble a natural water bottom, and the legs 22 protrude downward along the periphery of the lower surface. The bottom surface of the leg 22 is disposed so as to face the bottom surface of the water tank 10 with a space therebetween by contacting the bottom surface of the water tank. At one corner of the floor member 2, a rectangular parallelepiped recess 23 having a top surface opened and having a bottom surface is provided, and a shaft hole 24 through which a rotation shaft, which will be described later, passes is formed at the center of the bottom surface of the recess 23. A radial cut 25 is formed around the periphery of the shaft hole 24. At a diagonal position of the recess 23, there is provided a collection chamber 26 having a rectangular shape in plan view, the upper surface of which can be opened and closed by a lid 29 and which has no bottom surface.

  The collection chamber 26 is partitioned from the remaining space at the space between the lower surface of the floor member 2 and the water tank 10 by projecting downward along the periphery so that the skirt 27 substantially contacts the bottom surface of the water tank 10. It has a rectangular parallelepiped space. In the skirt 27, a plurality of slits 28 are formed in a portion parallel to the long side of the water tank 10, and water can enter and exit the collection chamber 26 through the slits 28.

  The rock member 3 is made of resin, has a box shape in which the lower half portion can be fitted into the recess 23 and the entire rear side is open, and the outer appearance of the upper half portion is shaped to resemble natural rock, and the shaft A shaft hole 31 having the same center line as the hole 24 is provided so as to penetrate in the vertical direction. Further, a window 32 communicating with the shaft hole 31 is formed near the upper end. A motor 41 is fixed to the upper end of the shaft hole 31.

The impeller 4 includes a rotation shaft 42 attached to the drive shaft of the motor 41 and passed through the shaft hole 31 and the shaft hole 24, and a stirring blade 43 attached to the lower end of the rotation shaft 42. A blade 44 is attached to the rotary shaft 42 at a position corresponding to the window 32.
The filter 5 is housed in the lower half of the rock member 3 so as not to interfere with the rotating shaft 42 and to surround it.
The storage box 6 is made of a transparent resin at the bottom, has a cylindrical portion surrounding the motor 41, and a lighting fixture and a power circuit (not shown) are stored outside the cylindrical portion.

  According to this embodiment, when water and fish are put into the aquarium 10, organic matter such as fish excrement and remaining bait passes through the water holes 21 and falls to the bottom surface of the aquarium 10. Therefore, the organic matter is difficult to see from the outside of the water tank 10. When the motor is driven, a vortex is generated under the floor member 2 by the stirring blade 43, and the organic matter passes through the slit 28 and is collected in the recovery chamber 26. The collected organic matter can be easily removed and collected by opening the lid 29 and sucking it up with a pump (not shown).

  Furthermore, in this embodiment, in addition to the action of the stirring blade 43, water is discharged from the window 32 as the blade 44 rotates, and at the same time, water around the filter 5 is filtered by the filter 5. As a result, the water in the water tank 10 can be kept clean. When the filter 5 is washed, the rock member 3 is lifted together with the rotating shaft 42 with the motor 41 stopped, and the rock member 3 is taken out together with the stirring blade 43 while elastically deforming the triangular piece sandwiched between the adjacent cuts 25. The filter 5 may be taken out.

  In this embodiment, the collection chamber 26 is integrated with the floor member 2, but is not limited thereto, and may be a detachable cartridge type. For example, a box-shaped cartridge tank having a slit similar to the slit 28 is used as the collection chamber 26. It may be placed in the position, and when the organic matter is accumulated, the tank may be taken out and opened to dispose of the organic matter.

Embodiment 2
The aquarium decorative body according to the second embodiment includes a magnetic stirring bar 7 instead of the impeller 4 as shown in FIG. The water tank 10 is placed on the magnetic stirrer 71. When the stirrer 71 is driven, the stirrer 7 is rotated by the action of magnetic force, and accordingly, a vortex is generated under the floor member 2, and the organic matter passes through the slit 28 and is collected in the recovery chamber 26. Since the impeller 4 is not required, the floor member 2 may not be provided with a shaft hole, and the rock member 3 may or may not be detachable from the floor member 2.
