Description

Technical Field

[0001] The utility model relates to the technical field of liquid purification, in particular to a dual-purpose device for fish tank liquid circulation and discharge. Background Art

[0002] With the progress of society and the acceleration of the pace of life, more and more people begin to look for hobbies that can relax the body and mind, decorate the space and improve the quality of life. Raising aquatic organisms is one of them. Compared with traditional square fish tanks, round fish tanks are favored by people because of their unique beauty and small floor area. At present, most of the filtering methods for round fish tanks on the market are to place the water pump into the tank body through the tank mouth, which not only occupies the activity space of aquatic organisms, but also affects the overall beauty of the fish tank. In addition, since the water pump is placed in water for a long time, there is a risk of electric leakage. And as more and more people like large-sized round fish tanks, the water capacity of large fish tanks is larger. When it is necessary to change water and clean the fish tank, the original fish tank liquid needs to be discharged. Large fish tanks are not only difficult to move, but also easy to be bumped and damaged during the moving process. What's more troublesome is that before and after each cleaning of the fish tank, it is necessary to remove and install related equipment such as water pumps, and the operation steps are cumbersome. Content of the Utility Model

[0003] In order to solve the above problems, the utility model provides a dual-purpose device for fish tank liquid circulation and discharge. Specifically, the technical scheme adopted is as follows:

[0004] A dual-purpose device for fish tank liquid circulation and discharge includes a container, a suction member and a liquid guide pipe. The container is provided with a liquid discharge port and an opening. The liquid in the container flows out through the liquid discharge port, and the liquid flows back into the container through the opening. The suction member is connected to the liquid guide pipe and conveys the inhaled liquid to the liquid guide pipe. The liquid guide pipe guides the conveyed liquid into the container for reflux or to the outside of the container for discharge.

[0005] Further, the liquid guide pipe is a pipe with a hollow interior and both ends communicating. The pipe orifice at the inlet end is communicated with the delivery port, and the pipe orifice at the outlet end extends to the opening of the container.

[0006] Further, when there is liquid in the container, the outlet end of the liquid guide pipe is set higher than the water level of the container. Due to the pressure difference, the liquid in the liquid guide pipe will not flow out by itself. When it is necessary to clean the container or change water and discharge the liquid, the outlet end is lowered to be lower than the water level of the container, and the liquid flows out naturally under the action of gravity or the suction member is operated to guide the liquid to the outside of the container, so as to conveniently complete the liquid replacement or container cleaning operation without moving the container.

[0007] Further, the liquid discharge port is provided at the bottom of the container. Since excrement or impurities will settle at the bottom, setting the liquid discharge port at the bottom can greatly improve the filtration effect. The liquid discharge port is communicated with the inside of the container, and the liquid and sediment flow out of the container through the liquid discharge port.

[0008] Further, a separation net can be provided at the upstream position of the liquid discharge port, and the separation net can prevent aquatic organisms from being sucked in.

[0009] Further, a base is provided at the bottom outside the container. The base can prevent the container from being knocked during daily use and can install the required components in the base space to improve the overall ornamental value.

[0010] Further, a quick connector is provided between the liquid discharge port and the liquid guide pipe. The quick connector is communicated with the liquid discharge port, and the suction member is connected or separated from the liquid guide pipe through the quick connector.

[0011] Further, the quick connector includes a push-in type, a threaded connection or a socket connection method to connect with the liquid guide pipe.

[0012] Further, the suction member can be an automatic pump or a manual suction source component, which is located outside the container.

[0013] Further, a liquid discharge regulator is also provided outside the container, which is provided at the downstream position of the liquid discharge port and is used to adjust or control the channel of the liquid flowing through the liquid discharge port, so as to control the outflow and flow rate of the liquid. The liquid discharge regulator is provided with a liquid inlet end and a liquid outlet end. The liquid inlet end is communicated with the liquid discharge port, and even if the outlet end of the liquid guide pipe is lower than the water level of the container, the liquid in the container can be adjusted whether to flow out.

[0014] Further, the liquid discharge regulator is equipped with a valve, including a manual valve switch and an electric adjustment switch. The manual valve switch realizes the adjustment of liquid discharge through manual opening and closing; the electric adjustment switch can be an electromagnetic valve, which adjusts the liquid discharge through electric drive.

[0015] Further, a filter element for placing the filter medium is also provided on the return path of the liquid flowing out of the liquid discharge port to the inside of the container. The filter element includes a bottom plate for supporting the medium, and the shape of the bottom plate can be rectangular, circular or other geometric shapes suitable for accommodating the medium.

[0016] Further, the edge of the bottom plate of the filter element extends upward and / or obliquely, or is combined with the adjacent side wall to form a space for accommodating the medium, preventing the medium from slipping out of the filter element.

[0017] Further, at the top of the edge extension of the bottom plate of the filter element, a flange extending outward is provided.

[0018] Further, the bottom plate and / or the extension part of the filter element are provided with water leakage openings. After the liquid flowing out of the container is filtered by the filter medium of the filter element, it flows back into the container through the water leakage openings, avoiding food residues and feces being immersed in water for a long time, and at the same time, the filter medium can be conveniently replaced or cleaned.

[0019] Further, the filter element includes a part that can be set at the opening or the base of the container. When located at the opening of the container, the filter element fits with the edge of the container opening and can be stably installed at the opening; when located at the base, the base is hollow inside and the bottom is sealed. Above the bottom of the base, there is a horizontal opening communicating with the internal space. The filter element enters the inside of the base through this horizontal opening. A limiting part is provided inside the base. The limiting part is horizontally connected to the lower edge of the horizontal opening and the inner wall, and is used to support and limit the position of the filter element while not affecting the downward flow of the liquid.

[0020] Further, the outlet end of the liquid guiding pipe can be extended or the direction can be changed for draining operation to drain the liquid to the outside of the container.

[0021] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0022] Excreta and impurities are easily deposited at the bottom of the container. Therefore, the liquid discharge port provided at the bottom of the container significantly improves the filtration efficiency. Through the cooperation of the suction part and the liquid guiding pipe, the liquid conveyed by the suction part can be diverted to the inside of the container for reflux or discharged to the outside of the container. The structure is simple, the cost is low, and the suction part is located outside the container, greatly reducing the interference with the activity space of aquatic organisms and improving the ornamental value of the fish tank. At the same time, the risk of electric leakage caused by placing the water pump in the water is avoided. A base is provided at the bottom of the container, which can protect the container from being bumped and hide components, improving the overall aesthetics. In addition, a filter element is also provided on the reflux path. The filter element can filter and purify the circulating liquid and quickly replace or clean the filter medium in daily life. Without moving the container, the liquid can be diverted to the outside of the container through the liquid guiding pipe, so as to conveniently replace and clean the liquid in the container, and the maintenance is simple.

The liquid discharge port 2 is located at the bottom of the container 1 and is in communication with the interior of the container 1. There are openings on the cylinder wall below the opening of the container 1 for the nozzle of the leading end 11 of the liquid guiding pipe 9 to enter the container 1 through the openings. The liquid guiding pipe 9 is a flexible silica gel hollow pipe, with its lower end being the leading-in end 10 and the upper end being the leading-out end 11. Below the openings on the cylinder wall, limiting members 18 are respectively provided at four positions, namely the front, rear, left, and right, on the inner wall of the container 1. The limiting members 18 are horizontally bonded and fixed to support the filtering member 12. The filtering member 12 is a disc-shaped bottom plate, whose size is adapted to the inner diameter of the opening of the container 1, and forms a space for accommodating the medium in combination with the adjacent wall of the container 1. The bottom plate of the filtering member 12 is provided with a plurality of water leakage ports 19. The liquid flowing out of the container 1 is filtered by the filtering medium 20 of the filtering member 12 and then flows back into the container 1. The positions of the openings and the limiting members 18 are both set above the water level when the container is in use.

[0043] A base 3 is provided at the bottom outside the container 1. The base 3 is a hollow body with a bottom surface at the upper end. The bottom surface is provided with an opening corresponding to the liquid discharge port 2 at the bottom of the container 1 and is adhesively bonded to the bottom of the container 1. It has a space inside that can accommodate the components required for installation. Through holes are respectively provided on the front side, rear side, and side surface of the base 3. The through hole on the front side is for the switch member 16 to protrude, the through hole on the rear side is for the power cord 15 to pass through and enter the space of the base 3, and the through hole on the side surface is for the liquid guiding pipe 9 to pass through.

[0044] A suction member 6 is provided in the space of the base 3. The suction member 6 has positive and negative terminal connectors. The suction member 6 is a water pump with a tubular liquid suction port 7 and a delivery port 8. A fixing frame is sleeved outside the pump body, and the fixing frame is installed on the inner bottom surface of the base 3 by an adhesive bonding method. The delivery port 8 of the suction member 6 is connected to the nozzle of the leading-in end 10 of the liquid guiding pipe 9, and the liquid suction port 7 of the suction member 6 is connected to one end of a conduit 13, and the other end of the conduit 13 is connected to the liquid discharge port 2.

[0045] A switch member 16 is provided on the front side of the base 3. The switch member 16 is a push-button switch with a self-locking function.

One terminal connector is connected to the positive pole of the power cord 15, and the other terminal connector is connected to the positive terminal of the suction member 6. The negative terminal of the suction member 6 is connected to the negative pole of the power cord 15. When the switch is pressed, the suction member 6 is energized and operates.

[0046] The circulation and discharge principle of this embodiment is as follows:

[0047] When the container 1 is filled with liquid, the liquid will flow to the liquid suction port 7 of the suction member 6 under the action of water pressure. The liquid suction port 7 is communicated with the delivery port 8. Therefore, the liquid will flow into the interior of the liquid guide pipe 9 through the delivery port 8. Since the outlet end 11 of the liquid guide pipe 9 is higher than the water level of the container 1, the liquid will not flow out from the drain port 2 due to the pressure difference. When the suction member 6 operates, it will transport the liquid to the nozzle at the outlet end 11 and flow out, and then return to the interior of the container 1 through the water leakage port 19 of the filter member 12, repeating this cycle.

[0048] When liquid needs to be drained from the container 1, the nozzle at the outlet end 11 of the liquid guide pipe 9 is pulled out from the opening in the cylinder wall, and the liquid is guided out of the container by using the liquid guide pipe 9. The drainage process can be accelerated when the suction member 6 is operating, or when the suction member 6 is turned off, the outlet end 11 can be lowered to a level lower than the water level of the container 1, and the liquid will flow out naturally under the action of gravity. Thus, the drainage operation can be quickly completed without moving the container 1, so as to clean and change the water in the container.

[0049] Embodiment 2

[0050] Referring to Figure 3 and Figure 4 , this embodiment provides a dual-purpose device for fish tank liquid circulation and drainage, including a container 1, a liquid guide pipe 9 and a suction member 6.

[0051] The container 1 is a circular fish tank, with a drain port 2 at the bottom communicating with the interior. The drain port 2 is larger than the outer diameter of the body of the liquid guide pipe 9. There is an opening at the top. At the position of the drain port 2 on the outside of the container 1, a quick connector 5 is provided. The quick connector 5 is a hollow body with one end bottom surface closed and the other end open. The open end covers the drain port 2 and is adhesively bonded to the bottom of the container 1. Two openings are provided on the bottom surface of the closed end, and one of the openings is located vertically below the drain port 2.

[0052] The suction member 6 is a water pump, provided with a tubular and communicating liquid suction port 7 and a delivery port 8. The delivery port 8 passes through the opening at the position vertically below the drain port 2 of the quick connector 5 and partially enters the interior of the quick connector 5. The part that enters is used to connect with the nozzle at the inlet end 10 of the liquid guide pipe 9. The liquid suction port 7 passes through the other opening on the bottom surface of the quick connector 5 and enters the interior. The suction member 6 and the quick connector 5 are connected by adhesive bonding.

[0053] A base 3 is provided at the bottom outside the container 1. The base 3 is a hollow cylinder, and its upper end is adhesively bonded to the bottom of the container 1. A switch through-hole is provided on the front side of the base 3 for the key switch of the switch member 16 to protrude. A wire passing hole is provided on the rear side for the power cord 15 to enter the interior of the base 3. The switch member 16 is a key switch with a self-locking function and is installed inside the base 3, and its key cap protrudes through the switch through-hole. The switch member 16 has two wiring terminals, one of which is connected to the positive pole of the power cord 15, and the other is connected to the positive wiring terminal of the suction member 6. The negative wiring terminal of the suction member 6 is connected to the negative pole of the power cord 15. When the switch is pressed, the suction member 6 is powered on and operates. After all components are assembled, a bottom surface 17 adapted to it is adhesively bonded to the lower end of the base 3.

[0054] A disc-shaped filter member 12 is installed at the opening of the container 1. The filter member 12 includes a bottom plate for supporting the medium.

The height of its outlet end is higher than the water level of the container 1.

[0056] The circulation and discharge principle of this embodiment is as follows:

[0057] When the container 1 is filled with liquid, the liquid will flow into the inside of the quick connector 5 through the liquid discharge port 2 under the action of water pressure. The suction member 6 operates, and the liquid suction port 7 sucks the liquid inside the quick connector 5 into the delivery port 8. Since the delivery port 8 is connected to the pipe orifice of the inlet end 10 of the liquid guide pipe 9, the transported liquid will not return to the inside of the quick connector 5, but is transported to the filter member 12 above through the liquid guide pipe 9. The liquid will flow downward under the action of gravity to the space filled with the filtering medium, and the filtered liquid will flow back downward through the water leakage hole 19 into the interior of the container 1, and so on in a cycle.

[0058] When the water in the container 1 needs to be drained, an extension pipe is connected to the pipe orifice of the outlet end 11 of the liquid guide pipe 9, and the liquid is guided to the outside of the container 1 by using the extension pipe, so that the liquid drainage operation can be quickly completed without moving the container 1.
