Abstract

An improved aquarium structure includes an aquarium body, which can be combined with a filtering device. The body is provided with a main partition to divide the body into a breeding chamber and a diversion chamber; the diversion chamber is provided with a secondary partition to divide the diversion chamber into a first space and a second space. The first space has a first partition and a (fluid) output port connected to the filtering device; and the second space is provided with a (fluid) input port and a (fluid) guide port. Therefore, the fluid in the culture chamber can enter the first space through the main partition, and enter the filtering device through the output port for filtering; the filtered fluid enters the second space through the input port, and is input into the culture chamber from the guide port (cooperating with the guide channel), thereby forming a fluid filtering circulation mechanism, and ensuring that the fluid in the culture chamber will not cause (excessive) loss of fluid and/or fail to circulate water normally to be injected into the aquarium due to external factors (or siphon phenomenon).

Description

Aquarium Improvement Structure

This work is about an aquarium structure; in particular, it is about an aquarium structure (combined filtration equipment) that achieves a technology to ensure that the fluid in the aquarium will not be lost due to siphoning (or external factors).

It is a known technology to use aquariums to cultivate aquatic plants, fish or the like for aesthetic/decoration, viewing and other purposes. Such aquariums are usually combined with filtering equipment to filter and purify the fluid in the aquarium to improve water quality and aquaculture ecology and increase the life span of aquarium aquaculture. For example, Taiwan Patent No. 83107694 "Aquarium Breeding Device Simulating Natural Ecology" and No. 102216929 "Water Exchange Device for Sedimentation Filtration" provide typical embodiments.

One of the issues concerning the structure and application of this type of aquarium and filtration equipment is that there are often some external factors (such as power outages, abnormal operation of the filtration equipment or motor, etc.) that interfere with or hinder the normal operation of the aquarium, causing siphoning to suck the fluid in the aquarium (backflow or reflux), resulting in the loss of fluid in the aquarium and/or the inability to circulate water into the aquarium normally.

In particular, in some special cases, excessive loss of fluid in the aquarium has affected the life of the cultured animals; this is not what we want.

Typically, these references show techniques for learning aquariums and related equipment or similar structures; if the structural type of the aquarium (or aquarium combination filtration equipment) is redesigned to make its structure different from that of the user, its usage form can be changed and different from the old method; or further, its structural type can be made to respond to changes in external factors to ensure that the fluid in the aquarium (or its breeding room) will not cause (excessive) loss of fluid due to siphoning and/or the water supply cannot be circulated normally into the aquarium.

These topics are not taught or specifically disclosed in the above-mentioned references.

Therefore, the main purpose of the invention is to provide an improved aquarium structure, including an aquarium body, the body (lower or bottom area) can be combined with a filtering device. The body is provided with a main partition, which divides the body into a breeding room and a diversion room; the diversion room is provided with a secondary partition, which divides the diversion room into a first space and a second space. The first space has a first partition and a (fluid) output port connected to the filtering device; and the second space is provided with a (fluid) input port and a (fluid) guide port. Therefore, the fluid in the culture chamber can enter the first space through the main baffle (or the main body, or the grating located in the main baffle area), so that the fluid enters the filtering device through the output port for filtering; the filtered fluid enters the second space through the input port, and is input into the culture chamber from the guide port (cooperating with the guide channel or conduit located at the bottom of the main body), thereby forming a fluid filtering circulation mechanism and ensuring that the fluid in the culture chamber will not be lost due to external factors (or siphon phenomenon) and/or cannot be circulated normally to supply water to the aquarium.

According to the improved structure of the aquarium of this invention, a first partition is provided in the first space (along the direction perpendicular to the axis of the body), and the first space is divided into a first main space and a first secondary space; the output port is provided in the (bottom) area of the first secondary space. Also, the height of the first partition is smaller than that of the main partition. Therefore, after the fluid in the breeding room enters (fills) the first main space from the grating hole, the fluid will pass through the first partition, enter the first secondary space, and be output from the output port, enter the filtering device, and perform fluid filtering (and/or purification) operations.

In particular, if an external factor (or siphon phenomenon) occurs to prevent the normal circulation movement (or filtering operation) of the fluid, even if (part of) the fluid flows out from the first secondary space through the outlet, the first partition can actually retain the fluid volume in the first main space and the culture chamber to prevent the fluid from being lost.

According to the improved structure of the aquarium of this invention, the second space (along the direction parallel to the axis of the body) is provided with a second partition and an auxiliary partition, and the second space is divided into a second main space, a second auxiliary space and a second auxiliary space; the input port is provided in the area of the second main space. And, the height of the second partition is smaller than that of the auxiliary partition. Therefore, after the fluid filtered (and/or purified) by the filtering device enters (fills) the second main space from the input port, the fluid will pass through the second partition, enter the second auxiliary space, and be injected into the breeding room from the guide port (cooperating with the guide channel), forming a (normal) circulation movement of the fluid.

In the feasible embodiment, the auxiliary partition (bottom area) is formed with a notch structure, so that the auxiliary space is connected to the second auxiliary space. Therefore, (part of) the fluid entering the second auxiliary space will enter (fill) the second auxiliary space through the notch; and the main body is provided with an auxiliary hole in the upper area of the second auxiliary space to prevent the occurrence of siphon phenomenon, and the auxiliary hole connects the second auxiliary space to the breeding room.

It is understood that, assuming that an external factor (or siphon phenomenon) occurs to block the normal circulation of the fluid, the fluid in the culture chamber enters the second subsidiary space or the second space through the subsidiary hole (backflow or reflux) due to the siphon phenomenon, and when the fluid height in the culture chamber is lower than the height position of the subsidiary hole, the state of the above-mentioned fluid continuing to reflux is blocked, thereby achieving the situation of retaining the fluid volume in the second space and the culture chamber and preventing the loss of fluid.

Please refer to Figures 1 and 2. The improved aquarium structure of the present invention includes an aquarium body, generally indicated by reference number 50; the body 50 defines an axis X. In addition, the body 50 (the lower or bottom area) can be combined with a filter device 90; the filter device 90 belongs to the known technology and is not described in detail.

In the following descriptions, when upper, top (upper end), lower, lower (lower end), bottom, side, etc. are mentioned, the directions shown in the figures are used as reference directions.

The figure shows that the main body 50 is provided with a main partition 30 along the axis X direction perpendicular to the main body 50, dividing the main body 50 into a culture chamber 55 and a diversion chamber 60 that can accommodate fluid; the diversion chamber 60 is provided with a secondary partition 40 along the axis X direction parallel to the main body 50, dividing the diversion chamber 60 into a first space 10 and a second space 20. The first space 10 has a first partition 11 and a (fluid) output port 12 connected to the filtering device 90. In addition, a closing plate 45 is provided on the second space 20; the second space 20 is provided with a (fluid) input port 28 and a (fluid) guide port 29. The input port 28 can cooperate with a delivery pipe 98 and connect to the filtering device 90, so that the filtered and/or purified fluid can enter the input port 28 and the second space 20 through the delivery pipe 98.

In the embodiment adopted, a plurality of (fluid) injection holes 56 are provided on one side of the bottom area of the body 50 (or the breeding chamber 55), and a plurality of (fluid) screen holes 35 are provided on the other side of the bottom area of the body 50 (or the breeding chamber 55) (or the bottom area of the main partition 30). Therefore, the fluid in the culture chamber 55 can enter the first space 10 through the grating 35 of the body 50 (or the main partition 30), so that the fluid enters the filtering device 90 through the output port 12 for filtering; the filtered fluid enters the second space 20 through the input port 28, and is input into the culture chamber 55 through the guide port 29 (cooperating with the guide channel 59 or the conduit located at the bottom of the body 50) through the injection port 56, thereby forming a fluid filtering circulation mechanism and ensuring that the fluid in the culture chamber 55 will not be lost due to external factors (or siphon phenomenon) and/or cannot be circulated normally to supply water to the aquarium.

2 and 3 , the first space 10 is provided with a first partition 11 along the axis X direction perpendicular to the main body 50, so as to divide the first space 10 into a first main space 18 and a first sub-space 19; the output port 12 is provided at the bottom (or bottom end) area of the first sub-space 19. In addition, the height of the first partition 11 is less than (or lower than) the main partition 30.

Therefore, after the fluid in the culture chamber 55 enters (fills) the first main space 18 through the grating 35, the fluid will pass through the first partition 11 and enter the first secondary space 19, and then be output from the output port 12 and enter the filtering device 90 for fluid filtering (and/or purification); for example, the situation depicted in FIG. 3 .

In particular, if an external factor (or siphon phenomenon) occurs to hinder the normal circulation movement (or filtering operation) of the fluid, even if (part of) the fluid flows out from the first secondary space 19 through the outlet 12, the first partition 11 can indeed retain the fluid volume in the first main space 18 and the culture chamber 55 to prevent (excessive) loss of the fluid.

In the embodiment adopted, the second space 20 is provided with a second partition 22 and an auxiliary partition 23 along the axis X direction parallel to the body 50, and the second space 20 is divided into a second main space 24, a second auxiliary space 25 and a second auxiliary space 26; the input port 28 is provided at the bottom area of the second main space 24. The height of the second partition 22 is less than (or lower than) the auxiliary partition 40. In addition, the closing plate 45 is conducive to the second space 20 (or the second main space 24, the second auxiliary space 25) to form a closed flow path.

Please refer to Figure 4. Therefore, after the fluid filtered (and/or purified) by the filtering device 90 enters (fills) the second main space 24 from the delivery pipe 98 through the input port 28, the fluid will pass through the second partition 22 and enter the second secondary space 25, and then be injected into the culture chamber 55 from the guide port 29 and the guide channel 59 through the injection hole 56, forming a (normal) circulation movement of the fluid.

In a feasible embodiment, the accessory partition 23 (bottom area) is formed with a notch 27 structure, so that the second accessory space 26 is connected to the second auxiliary space 25. Therefore, (part of) the fluid entering the second auxiliary space 25 will enter (fill) the second auxiliary space 26 through the notch 27; and the main body 50 is provided with an accessory hole 58 in the upper area of the second auxiliary space 26 to prevent the generation of a siphon phenomenon, and the accessory hole 58 connects the second auxiliary space 26 to the culture chamber 55.

It is understood that, assuming that an external factor (or siphon phenomenon) occurs to block the normal circulation of the fluid, the fluid in the culture chamber 55 enters the second auxiliary space 26 or the second space 20 through the auxiliary hole 58 (backflow or reflux) due to the siphon phenomenon, and when the fluid level in the culture chamber 55 is lower than the height of the auxiliary hole 58, (the intervention of air) blocks the above-mentioned siphon phenomenon (destroying the closed flow path) or the state where the fluid continues to reflux, thereby achieving the situation where the fluid volume in the second space 20 and the culture chamber 55 is actually retained and the fluid loss is prevented.

Please refer to FIG. 5 and FIG. 6 (and/or FIG. 2 ), the main body 50 is provided with a first auxiliary partition 17 (and/or a stop partition 15 parallel to the axis X direction) at one end of the first space 10 (or a region away from the second space 20) along the axis X direction parallel to the main body 50; the first auxiliary partition 17 (and/or the stop partition 15) defines a first auxiliary space 16 in the main body 50 (or the first space 10). Therefore, after the fluid in the above-mentioned culture chamber 55 enters (fills) the first main space 18 from the grating 35, the fluid will also pass through the stop partition 15 and enter the first auxiliary space 16.

In the embodiment adopted, the main body 50 (or the upper area of the main partition 30 adjacent to the first space 10, or the upper area of the main partition 30 away from the second space 20) is provided with a plurality of auxiliary screen holes 57, and the main body 50 is provided with an auxiliary output port 13 at the bottom of the first auxiliary space 16; the auxiliary output port 13 can be connected to the pipeline 95 (and/or the control valve (not shown), the filtering device 90), providing the function of regular or irregular automatic drainage, water replacement (or removal of suspended matter).

The figure also depicts that the first auxiliary partition 17, the main partition 30, and the first sub-partition 11a define the first auxiliary sub-space 17a, and the first auxiliary sub-space 17a is connected to the sub-grating hole 57. The first sub-partition 11a can be separately arranged in the body 50 (or the first space 10), or the first sub-partition 11a and the first partition 11 form an integral structure. In addition, the first sub-partition 11a (or the first partition 11) is provided with a through hole 14 in the lower area; the through hole 14 connects the first auxiliary sub-space 17a to the first sub-space 19.

In the embodiment adopted, the height of the auxiliary screen hole 57 is higher than the height of the stop baffle 15, and the height of the stop baffle 15 is lower than the first baffle 11 (or the first auxiliary baffle 17); the height of the first auxiliary baffle 17 is not greater than (or less than, equal to) the height of the main baffle 30, and the height of the first auxiliary baffle 17 is greater than the height of the first baffle 11.

Therefore, the auxiliary screen hole 57 allows the upper layer or top layer fluid of the culture chamber 55 (and/or the floating matter floating on the upper layer of the fluid in the culture chamber 55) to enter the first auxiliary auxiliary space 17a (cooperating with the first auxiliary baffle 17 and/or the first auxiliary baffle 11a to prevent the floating wastewater entering the first auxiliary auxiliary space 17a from generating a backflow), enters the first auxiliary space 19 through the through hole 14, and then enters the filtering device 90 from the output port 12 for filtering (and/or purification) operation.

FIG. 5 and FIG. 6 (and/or FIG. 2 ) also depict that, assuming that the main body 50 is to perform a water replacement (or drainage) operation, the personnel can operate to discharge the fluid from the auxiliary output port 13; the height of the stop baffle 15 is lower than the first baffle 11 (and/or the main baffle 30, the first auxiliary baffle 17), so assuming that in the case of personnel negligence (or other external factors), even if the fluid in the first auxiliary space 16 is completely discharged from the auxiliary output port 13, the stop baffle 15 can be used to keep the fluid height of the entire breeding room 55 approximately equal to the height of the stop baffle 15, and the fluid will not be completely emptied (or backflow) will not occur.

In short, the function of the stop baffle 15 is to stop the fluid from being completely discharged from the secondary output port 13.

It should be noted that the above-mentioned grating holes 35, auxiliary grating holes 57 and/or auxiliary holes 58 can be directly formed on the main partition 30, and the first partition 11 can also extend to the first auxiliary auxiliary space 17a (forming the above-mentioned first auxiliary partition 11a). Furthermore, the above-mentioned embodiments show that the main partition 30 cooperates with the sub-partition 40 to jointly define the second space 20, the main partition 30 cooperates with the first auxiliary partition 17 (and/or the first partition 11, the first sub-partition 11a) to jointly define the first auxiliary sub-space 17a, and the main partition 30 (and/or the first partition 11) cooperates with the first auxiliary partition 17 and the stop partition 15 to jointly define the first auxiliary space 16; in other words, the sub-partition 40 can also cooperate with another partition (not the main partition 30) to jointly define the second space 20, and the first auxiliary partition 17 can also cooperate with another partition (and/or the first sub-partition 11a) other than the main partition 30 to jointly define the structure of the first auxiliary sub-space 17a. Furthermore, the outlet 12, the inlet 28, the guide port 29, the screen hole 35, the injection hole 56, the guide channel 59 and/or the filtering device 90 are arranged below or at the bottom area of the main body 50, which is helpful to assist in removing (or purifying) dirt or the like located at the bottom layer of the main body 50 (or the culture chamber 55).

Typically, this improved aquarium structure has the following advantages over the old method:

1. The main body 50 and related component structures have been redesigned. For example, a guide channel 59 and a delivery pipe 98 are provided below or at the bottom of the main body 50, and a filter device 90 is combined; the main body 50 is provided with a flow chamber 60, a main partition 30, and a secondary partition 40, which together define a first space 10 and a second space 20. The first space 10 is provided with a first partition 11 to define a first main space 18, a first secondary space 19, and an outlet 12 disposed at the bottom of the first secondary space 19; the second space 20 is provided with a second partition 22 and an auxiliary partition 23 with a notch 27 (at the bottom), thereby defining a first main space 18, a first secondary space 19, and an outlet 12 disposed at the bottom of the first secondary space 19. The first main space 24, the second sub-space 25, and the second sub-space 26; the main body 50 is provided with a first sub-partition 17 to define the first sub-space 16, the bottom area of the main body 50 is provided with a screen 35 and an injection hole 56, the main body 50 is provided with a first sub-partition 17, a stop screen 15, a first sub-space 16, and a first sub-sub-space 17a, and the upper area of the main body 50 is provided with a sub-screen 57, etc., which are obviously different from those of the users and also change the known structure or combination relationship, so that its use and operation mode are different from the old method.

2. In particular, the structural form of the body 50 can be adapted to changes in external factors to ensure that the fluid in the aquarium (or breeding chamber 55) will not be lost due to siphoning and/or water cannot be circulated normally to be injected into the aquarium (or breeding chamber 55). This significantly improves the structure and application of the known aquarium (and/or filtration equipment), which is often disturbed or hindered by some external factors in the normal operation of the aquarium, resulting in siphoning (backflow or reflux) to suck the fluid in the aquarium, causing the loss of fluid in the aquarium and/or the failure to circulate water normally to be injected into the aquarium, or excessive loss of fluid in the aquarium, which affects the life of the cultured animals.

Therefore, this invention provides an effective improved aquarium structure, the spatial form of which is different from the known one and has advantages that cannot be compared with the old method. It shows considerable progress and fully meets the requirements of a new patent.

However, what is described above is only a feasible implementation example of the present invention and is not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of the patent application for the present invention are covered by the patent scope of the present invention.
