Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to an aquarium placed on top of an aquarium of ornamental fish such as goldfish and tropical fish, and used to circulate the water in the aquarium and purify the water in the aquarium. For filters.

In particular, the present invention stores a filter for water purification in a watertight pack, and circulates water in the pack, so that when the filter for water purification is fouled, touch the dirty filter inside. The present invention relates to a filter pack for an aquarium, which allows replacement of the filter.

[Technical background of the invention and its problems] A top-mounted filter device used for purifying water in an aquarium is a box-shaped filter accommodating case that is hung on the upper part of the aquarium, and is housed inside the box. It is composed of a water purification filter such as a matte or activated carbon filter, a pump that pumps water in the aquarium to the filter in the case, and a drain port provided in the storage case for dropping the purified water into the aquarium. . In addition, the storage case has a flow path for dispersing pumped water to each part of the water purification filter,
A lid for the storage case is also provided to cover the filter.

In such a filter device, dust in the water tank, fish feed, etc. become sludge and adhere to the filter, so it is necessary to replace the filter at regular intervals. Since the filter is stored directly, it is necessary to touch the filter when replacing the dirty filter, which is uncomfortable and not hygienic. Moreover, since the dirty filter contains water, when taking it out from the storage case, water may drop and stain the surroundings, so prepare a bucket etc. on the side of the water tank and quickly filter from the storage case. It had to be taken out, which made it difficult to work. Furthermore, if the filter is stored directly in the case, dirt will adhere not only to the filter but also to the inner surface of the case.Therefore, it is necessary not only to replace the filter, but also to remove it from the water tank and clean it. Considering these, the conventional filter replacement was very troublesome.

[Object of the Invention] It is an object of the present invention that when replacing the filter, it is not necessary to touch the dirty filter, and there is no risk of water dripping around, and the filter is stored as it is in the storage case of the conventional filter device. Another object of the present invention is to provide a filter pack for an aquarium that can be used and does not stain the storage case.

[Summary of the Invention] The filter pack of the present invention contains the entire filter for water purification in a watertight pack. The filter pack is set in a storage case of a conventionally known filter device, and the upper part of the pack is set. The water in the water tank is poured into the purifying filter in the pack through the inlet provided in the pack to purify it, and the purified water is discharged from the outlet provided in the pack to the drain of the storage case.

According to the present invention having such a configuration, the water purification filter,
Since it is set in the storage case of the filter device while being stored inside the pack, the inside of the storage case will not be contaminated and the filter can be taken out of the storage case together with the pack during replacement. Eliminates the need to touch the dirty filter in. Further, since the filter containing water is also stored in the pack, the water of the filter does not drip around even if the filter is taken out from the storage case.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings.

In the exploded perspective view of FIG. 1, reference numeral 1 is a box-shaped tray portion having an open top, and the tray portion 1 is formed of a relatively thin synthetic resin molded product. First, activated carbon filters 2 and 1 are stored in the tray portion 1. As the activated carbon filters 2 and 2, two activated carbons housed inside a net are arranged side by side like the one used in the conventional purifying device. In order to prevent the two activated carbon filters 2, 2 from moving at the bottom of the tray part 1, a positioning projection 3 is provided at the bottom of the tray part 1 as shown in the sectional view of FIG. . Also, this activated carbon filter
A plurality of convex portions 4 are provided in the longitudinal direction of the tray portion 1 for supporting the trays 2 and 2 in a state of being lifted from the bottom portion of the tray portion 1.

A discharge port 5 for discharging water in the tray portion 1 is provided on one end surface of the tray portion 1. The position of the discharge port 5 may be at the lower part of the end face or at the upper part of the end face, but in the present embodiment, the lower end of the end face is prevented so that water will not be spilled even if the tray part 1 is lifted while some water remains inside. It is provided slightly above.

Above the activated carbon filters 2 and 2 in the tray unit 1,
A mat-shaped filter 6 is stored. As the mat-shaped filter 6, for example, a filter in which a coarse filter 6a and a fine filter 6b are integrally laminated is used. Of course, only one type of filter is required.

The upper opening portion of the tray portion 1 is first closed by the flow path inner lid 7. The inner lid 7 is heat-welded to the flange portion around the tray portion 1 at the flange portion around the inner lid 7. The central portion of the inner lid 7 is lowered by one step as compared with the flange portion, and this lowered portion serves as a flow path 8 for dispersing circulating water from the water tank to each portion of the filter.
A plurality of holes 9 for pouring the circulating water from the flow path 8 to the filter in the tray portion 1 are provided at the bottom of the flow path 8. In addition, a filter is provided by the bottom of the flow path 8.
The tray portion 1 is pressed so as not to move carelessly.

The upper opening of the inner lid 7 is closed by a plate-shaped lid 10. Like the inner lid 7, the lid portion 10 is also heat-welded to the flange portion of the tray portion 1. This heat welding is performed all at once with the tray portion 1, the inner lid 7, and the lid portion 10 being stacked. An outlet 11 is provided on the upper surface of the lid 10 to allow the circulating water from the water tank to flow into the flow path 8 between the lid 10 and the inner lid 7. The inflow port 11 is provided at a position higher than the discharge port 5, and the water that has flowed into the tray portion 1 from the inflow port 11 is discharged from the discharge port 5. The position of the inflow port 11 is provided on the opposite side of the discharge port 5 so that the circulating water is supplied over the entire area of the filter.

In order to use the filter pack of the present embodiment having such a structure, as shown in FIG. 2, a filter pack having a filter enclosed therein is provided in the case of a conventionally known purifying device provided at the upper part of the water tank. Set it up, use a suction pump to pump up dirty water for the aquarium, and pour it into the inlet 11 of the filter pack. The circulating water that has flowed into the inflow port 11 flows through the channel 8 and spreads over the entire area of the filter pack, and is poured into the upper surface of the mat-shaped filter 6 from the hole 9 at the bottom of the channel 8. First by the mat filter 6
The purified water of the stage reaches the activated carbon filters 2, 2 in the stage below it, where it is adsorbed with dirt and becomes cleaner and goes to the outlet 5. At this time, since the gap is formed between the activated carbon filters 2, 2 and the bottom portion of the tray portion 1 by the convex portion 3, water easily flows. of course,
Water can flow to the discharge port 5 through the activated carbon filters 2, 2 without this gap.

In this case, since the water from the discharge port 5 is purified and becomes clean, the filter storage case of the purification device supporting the filter pack of the present embodiment is different from the conventional case where the filter is directly set. The dirt is much less.

Further, if the internal filter becomes dirty as a result of long-term use, the filter can be replaced without touching the dirty filter by removing the internal filter together with the filter pack from the storage case. In particular,
In this embodiment, since the outlet is provided at a position higher than the bottom of the tray unit 1, the inside of the filter pack is lifted by the inlet 11 side of the filter pack and the water inside is spilled from the outlet 5. For example, even if the filter pack is lifted from the storage case, water does not spill and the filter can be replaced without polluting the surrounding area.

[Other Embodiments] The present invention is not limited to the above-described embodiments, and also includes the following other embodiments.

A filter that uses only mat-shaped filters.

Circulating water is poured directly from the inlet to the filter without providing a flow path inside.

As shown in FIG. 4, a nozzle 20 is provided at the discharge port so that the water from the discharge port does not directly drop on the water surface of the aquarium to contaminate the filter pack or the storage case supporting it. The nozzle 20 may be provided integrally with the tray portion, or may be provided as a separate member and inserted into the discharge port or joined.

A filter is provided at the outlet to prevent the fine particles of the activated carbon filter generated at the beginning of use from flowing into the water tank. It should be noted that this filter may be detachably attached to the discharge port, and may be removed when the waste from the activated carbon filter is no longer present. Also, it may be attached to the tip of the nozzle.

As shown in FIG. 5, a partition wall 30 is provided on the lower surface of the inner lid, and the partition wall 30 divides the filter storage portion and the discharge port, and the partition wall 30 has an opening portion 31 communicating between them, The one that overflows the clean water from the outlet.

The handle part is formed by overhanging the upper flange part of the filter pack a little, and the handle part is used to drain water from the pack, or the handle part is used to remove the filter pack from the storage case.

The bottom of the tray is inclined toward the outlet so that the water inside will flow smoothly to the outlet.

The pack is made of transparent material, and the dirt on the internal filter can be easily seen from the outside.

The strength of the pack containing the filter is high, and the filter pack can be supported directly on the top of the water tank without using a separate storage case.
