Description

Technical Field

[0001] The invention relates to the technical field of fish tank filtration, and in particular to a fish tank water quality regulating device and an intelligent fish tank. Background Art

[0002] After adding water to the fish tank, the fish live in the fish tank. The fish eat, drink, defecate and urinate in the fish tank. Therefore, the water quality treatment capacity of the fish tank filter is particularly important. At present, the fish tank filters on the market all rely on the experience and judgment of fish lovers, manually clean the filter cotton, and change the water in the fish tank. However, due to the uneven experience of fish lovers in fish farming and the inability to ensure timely and scientific water changes, it is easy to cause fluctuations in the water quality of the fish tank. Manually cleaning the filter cotton increases the chance of secondary pollution, which poses a greater hidden danger to fish farming safety. In addition, because of the daily care of feeding, changing water and cleaning ornamental fish, fish farmers have many concerns when they go out for travel and vacation. The custodial institutions on the market need to operate on-site, which has caused a great mental burden on fish farmers.

[0003] Therefore, the development of an artificial intelligence fish tank that can solve the problems of difficulty in keeping fish alive, changing water, and hosting is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] A first aspect of the present invention provides a fish tank water quality regulating device.

[0006] A second aspect of the present invention provides a smart fish tank.

[0007] In view of this, according to a first aspect of the present invention, there is provided a fish tank water quality regulating device, comprising: a cylinder body, on which an inlet and an outlet are arranged; a filtering device, which is connected with the inlet and the outlet of the cylinder body, so that water in the cylinder body can flow into the filtering device through the outlet of the cylinder body, and the filtering device can filter the inflowing water; a circulating device, which connects the cylinder body and the filtering device to realize water flow exchange between the cylinder body and the filtering device through the operation of the circulating device; and a water quality intelligent control device, which is connected with the filtering device and the circulating device, and can control the operation of the filtering device and the circulating device.

[0008] The fish tank water quality regulation equipment provided by an embodiment of the present invention includes a tank body, a filtering device, a circulating device, and a water quality intelligent control device. Among them, the filtering device is connected to an inlet and an outlet provided on the tank body. The water in the tank body can enter the filtering device through the outlet. After the water is filtered by the filtering device, through the operation of the circulating device, the filtered water is pumped back into the tank body from the filtering device, realizing the circulation of water between the tank body and the filtering device, and further forming a 24-hour physical and biochemical circulation filtration. Further, the water quality intelligent control device is connected to the filtering device and the circulating device, and can control the operation of the filtering device and the circulating device to realize the intelligentization of the fish tank water quality regulation equipment. The fish tank water quality regulation equipment of the present invention can realize artificial intelligence management with a relatively high degree of automation, does not require manual cleaning of the filter element of the fish tank water quality regulation equipment, does not require a large amount of working hours for changing water, does not require fish farmers to have fish-raising knowledge, and scientifically manages the fish tank through artificial intelligence, effectively ensuring the stability of water quality, promoting the improvement of the ornamental value and convenience of fish-raising, and further playing a great role in promoting the development of the aquarium industry.

[0009] In addition, the fish tank water quality regulation equipment provided by the above technical solution of the present invention further has the following additional technical features:

[0010] In a possible design, the filtering device includes: a sedimentation tank connected to the outlet of the tank body, and the water in the tank body can flow into the sedimentation tank; a washing bin; a water collecting box arranged in the washing bin, the water collecting box is located in the upper part of the washing bin, the water collecting box is snap-connected to the inner wall of the washing bin, and a water outlet is provided at the center of the water collecting box; a filter element arranged in the washing bin, the filter element is connected to the water collecting box, and the water flowing out of the water outlet of the water collecting box is filtered through the filter element.

[0011] In this design, it is further defined that the filtering device includes a sedimentation tank, a washing bin, a water collecting box, and a filter element. Among them, the sedimentation tank is connected to the outlet of the tank body. After the tank body and the filtering device are filled with water, the circulating device starts to pump water, and injects the filtered water in the filtering device into the tank body. After the liquid level in the tank body rises, it flows into the sedimentation tank of the filtering device through the outlet, and primary separation is completed in the sedimentation tank. The feces and residual bait with a large specific gravity settle at the bottom of the sedimentation tank, and the sewage with a small specific gravity flows into the water collecting box. It can be understood that because the water body of the sedimentation tank is large, the speed of the water coming from the fish tank is reduced, and the feces and residual bait with a large specific gravity naturally settle at the bottom. Further, the water collecting box is arranged in the washing bin. Specifically, steps can be provided on the inner wall of the washing bin, and the water collecting box is installed at the steps on the inner wall of the washing bin through a card slot to realize the snap connection between the water collecting box and the washing bin. Further, the outer end surface of the bottom of the water collecting box is a plane, which is convenient for realizing the connection between the water collecting box and the washing bin. A water outlet is provided at the center of the water collecting box, and the water returned from the tank body flows into the filter element through the water outlet, and the water returned from the tank body is filtered through the filter element.

[0012] In a possible design, the filter core includes: a cotton core body, which is in a plate shape, a bowl shape with an upward opening, or a barrel shape with an upward opening; and a buoyancy ring, which is arranged at the upper edge of the cotton core body.

[0013] In this design, it is specifically described that the filter core includes a cotton core body and a buoyancy ring. The cotton core body is composed of a composite material. For example, it is composed of a cotton and linen fiber filter cotton board to form a plate shape, a bowl shape, or a barrel shape. The buoyancy ring is arranged at the upper edge of the cotton core body (barrel shape, bowl shape, plate shape). The combined filter core has upward buoyancy and restoring force. After being washed and rubbed by the washing device, the mouth of the filter core still remains upward, rises with the water surface, and approaches the bottom of the water collection box. The mouth of the filter core is aligned with the water outlet at the center of the bottom of the water collection box. In order to avoid the filter core curling and overlapping during the washing and rubbing process, an appropriate counterweight or support block can be provided at the center of the filter core.

[0014] Further, the water outlet of the water collection box can be tubular or have countless dense pores dispersed, corresponding to a filter core of a suitable shape. If the filter core is in a plate shape or a bowl shape, it can correspond to a water outlet with countless dense pores in a scattered manner. If the filter core is in a barrel shape, it can correspond to a tubular water outlet.

[0015] Preferably, the water outlet is tubular, and the corresponding filter core is in a barrel structure. An appropriate counterweight is provided at the midpoint of the bottom of the barrel of the filter core. In this way, it can be ensured that the filter core can stand upright after being impacted by water flow and washed and rubbed, with the barrel mouth floating upward on the water surface. As the water surface rises, the barrel mouth approaches the bottom of the water collection box and aligns with the water outlet.

[0016] In a possible design, the fish tank water quality adjustment device further includes: a guiding ring, which is arranged in the washing chamber. The guiding ring is configured as a bowl shape with both ends open, and the two open ends of the guiding ring are of different sizes. The small open end of the guiding ring faces upward and fits with the bottom of the water collection box, and the large open end of the guiding ring is connected to the inner wall of the washing chamber.

[0017] In this design, a guiding ring is also arranged in the washing chamber. The guiding ring is configured as a barrel-shaped structure similar to a bottomless bowl, with the small head facing upward and tightly attached to the bottom plane of the water collection box. The large open end of the guiding ring is connected to the inner wall of the washing chamber. For example, the large open end of the guiding ring is seated on the inner wall slot of the washing chamber and is hermetically connected to the inner wall of the washing chamber. The guiding ring can play a role in straightening the filter core. In this way, it can be ensured that after being impacted by water flow and washed and rubbed, the filter core can stand upright under the straightening action of the guiding ring, with the barrel mouth floating upward on the water surface. As the water surface rises, the barrel mouth approaches the bottom of the water collection box and aligns with the water outlet.

[0018] In a possible design, the fish tank water quality adjustment device further includes: a flow channel disposed on the guiding ring, and the water in the washing chamber flows out through the flow channel after passing through the filter element; a biochemical chamber, the biochemical chamber is connected to the guiding ring through the flow channel, and the biochemical chamber is connected to the cylinder body.

[0019] In this design, a flow channel is provided on the guiding ring. For example, the flow channel is disposed at the waist of the guiding ring. After the fine particles in the fish tank water are physically intercepted and filtered by the filter element, the purified water seeps out from the pores of the filter element, flows through the flow channel at the waist of the guiding ring to the biochemical chamber, and is injected into the cylinder body through the circulation water pump in the biochemical chamber, forming a 24-hour physical and biochemical circulation filtration.

[0020] In a possible design, the fish tank water quality adjustment device further includes: a bacterial house disposed in the biochemical chamber.

[0021] In this design, a bacterial house with porous materials for breeding bacteria is provided in the biochemical chamber, which can enable the bacteria to multiply and form a nitrifying flora. The water passing through the filter element flows through the flora in the biochemical chamber for biochemical reactions, and the toxic substances such as ammonia nitrogen and nitrite in the water are degraded and neutralized. The biochemical chamber and the washing chamber can be of an integral structure or a split structure. The biochemical chamber and the washing chamber cooperate together to achieve the filtration of the water in the fish tank and the degradation and neutralization of toxic substances, so that the water quality after being treated by the fish tank water quality adjustment device can continue to be used for fish farming.

[0022] In a possible design, the number of biochemical chambers is multiple, and the multiple biochemical chambers are connected in series; the circulation device includes: a circulation water pump disposed in the last-stage biochemical chamber among the multiple biochemical chambers, the circulation water pump is connected to the inlet of the cylinder body, and the circulation water pump is connected to the water quality intelligent control device.

[0023] In this design, according to the size of the fish tank water body, multiple biochemical chambers can be designed. For example, additional split-type biochemical chambers are added. The multiple biochemical chambers are connected in series through a pipe manifold. The circulation water pump is placed in the last-stage biochemical chamber and connected to the inlet of the cylinder body. The circulation water pump is connected to the water quality intelligent control device. The water quality intelligent control device can control the operation of the circulation water pump to realize the transportation of the water in the biochemical chamber to the cylinder body, and further realize the regular automatic water replenishment and water change for the cylinder body to ensure that the water in the cylinder body is suitable for fish survival.

[0024] In a possible design, the fish tank water quality adjustment device further includes: a lower pipe manifold; a washing sewage pump disposed in the washing chamber, the washing sewage pump is connected to the water quality intelligent control device, and the washing sewage pump can extract the sewage in the washing chamber to the lower pipe manifold; a sedimentation sewage pump disposed in the sedimentation tank, the sedimentation sewage pump is connected to the water quality intelligent control device, and the sedimentation sewage pump can extract the sewage in the sedimentation tank to the lower pipe manifold.

[0025] In this design, the fish tank water quality regulation equipment further includes a downpipe assembly, a washing sewage pump, and a sediment sewage pump. During the circulation process, since feces and residual bait with a large specific gravity settle at the bottom of the sedimentation tank, in order to ensure water quality, it is necessary to clean this part of the dirt. Therefore, a sediment sewage pump is provided in the sedimentation tank, which is used to regularly extract the sediment at the bottom of the sedimentation tank according to the program settings of the water quality intelligent control device, and extract the sewage and sediment into the downpipe assembly together, and then discharge it through the downpipe connected to the downpipe assembly to achieve automatic sewage discharge; further, a washing sewage pump is provided in the washing tank, which is used to discharge sewage from the washing tank after washing the filter element. Specifically, when the filter element cleaning is completed, the washing sewage pump at the bottom of the washing tank starts to discharge sewage into the downpipe assembly, and then discharges it through the downpipe connected to the downpipe assembly to achieve automatic sewage discharge.

[0026] In a possible design, the fish tank water quality regulation equipment further includes: a washing device, connected to the water quality intelligent control device, the washing device is arranged in the washing tank and connected to the filter element, and the washing device can clean the filter element.

[0027] In this design, a washing device is also arranged in the washing tank, and the washing device can clean the filter element. For example, the washing power can create water flow in the water body by means of water pump flushing, agitator rotation, etc. The washing device of the present invention preferably uses a triangular motor of a washing machine as the power, and is connected to the agitator at the bottom of the washing tank through a speed reducer. The motor drives the agitator to create water flow in the water body, so that the filter element is stirred with the water flow, and the dirt and the filter element are separated under the action of centrifugal force and eddy current. Further, in order to dehydrate the filter element, the washing power can select the power structure of a fully automatic agitator washing machine, and an inner dehydration barrel, a clutch, and an agitator are added to the washing tank to form a dehydration structure. The inner barrel is driven to rotate by the program circuit and the holding spring to achieve dehydration.

[0028] In a possible design, the fish tank water quality regulation equipment further includes: a make-up water solenoid valve, connected to the water quality intelligent control device, and the make-up water solenoid valve is arranged on the pipeline connected to the inlet of the cylinder body; a low-level sensor of the washing tank, arranged in the washing tank and connected to the water quality intelligent control device, when the low-level sensor of the washing tank sends a signal, the water quality intelligent control device can control the circulation water pump and the make-up water solenoid valve to start working; a high-level sensor of the washing tank, arranged in the washing tank and connected to the water quality intelligent control device, when the high-level sensor of the washing tank sends a signal, the water quality intelligent control device can control the circulation water pump and the make-up water solenoid valve to stop working.

[0029] In this design, in order to better achieve the function of sewage separation and self-cleaning of the fish tank, after automatically cleaning the filter element, it is also possible to automatically supplement new water to complete small-dose water change in a cycle. The fish tank filtering device further includes a water replenishing solenoid valve, a low-level sensor of the washing bin, and a high-level sensor of the washing bin. Specifically, when the filter element cleaning is completed, the washing and sewage discharging pump at the bottom of the washing bin starts to discharge sewage to the sewer manifold. After the sewage is emptied, the low-level sensor of the washing bin at the bottom of the washing bin sends a signal, and the water quality intelligent control device sequentially starts the water replenishing solenoid valve and the circulating water pump works. The water in the biochemical bin is sucked by the circulating water pump, passes through the water replenishing solenoid valve, and is injected into the washing bin. When the liquid level reaches the high water level, the high-level sensor of the washing bin cuts off the circuit, and the water replenishing of the washing bin is completed. At this time, if secondary washing is required, the water quality intelligent control device sequentially starts the procedures of washing, sewage discharging, and water replenishing. After the set automatic washing program is completed, the system program automatically switches to the circulating physical and biochemical filtration mode for periodic circulation.

[0030] In a possible design, the fish tank water quality regulating device further includes: a standby water tank communicated with the filtering device; a water inlet arranged on the standby water tank; and a partition arranged in the standby water tank, and the partition can isolate the space in the standby water tank into multiple independent sub-spaces.

[0031] In this design, the fish tank water quality regulating device is equipped with a standby water tank. The standby water tank can be separately arranged from the filtering device or combined into an integral body. From the perspective of easy handling, a preferred embodiment of the present invention selects to place the filtering device and the standby water tank separately. The standby water tank is provided with a water inlet and a partition. The water inlet is connected to the tap water pipeline by a first float valve switch to ensure the liquid level of the standby water tank. Multiple partitions are arranged in the middle of the standby water tank to isolate the space in the standby water tank into multiple independent sub-spaces, which are respectively used to store new water and well-aired old water. The bottom of the standby water tank is connected to the biochemical bin by a second float valve switch. When the liquid level in the biochemical bin drops, the second float valve switch in the biochemical bin drops with the liquid level, and the water supply switch opens. The water in the standby water tank sequentially displaces along the partition into the biochemical bin. When the liquid level in the biochemical bin rises to a certain height, the second float valve switch rises with the liquid level to close, realizing the water replenishing work. At the same time, the water level of the standby water tank drops, and the first float valve switch drives the water replenishing switch to realize the injection of tap water, and new water displaces old water along the partition into the biochemical bin. After the water replenishing is completed, the first float valve switch of the standby water tank closes the water replenishing switch with the rise of the liquid level.

[0032] According to the second aspect of the present invention, the present invention provides an intelligent fish tank, including the fish tank water quality regulating device provided in any embodiment of the first aspect. Therefore, the intelligent fish tank provided by the embodiments of the present invention has all the beneficial effects of the fish tank water quality regulating device provided in any embodiment of the first aspect, which will not be listed one by one here.

[0033] In a possible design, the intelligent fish tank further includes: an automatic feeding device, which is connected to the water quality intelligent control device of the fish tank water quality regulation equipment, and the automatic feeding device can automatically feed according to the feeding regime generated by the water quality intelligent control device.

[0034] In this design, the intelligent fish tank further includes an automatic feeding device connected to the water quality intelligent control device. After the system generates a scientific diet regime, fish-keeping users can select an automatic feeding device with automatic feeding function. Users can set the dose per meal and the number of feedings per day to achieve automatic feeding.

Detailed implementation manners

[0044] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0046] The following refers to Figures 1 to 5 to describe the fish tank water quality adjustment equipment 100 and the intelligent fish tank provided according to some embodiments of the present invention.

[0047] As Figure 1 and Figure 2 shown, an embodiment of the first aspect of the present invention provides a fish tank water quality adjustment equipment 100, including: a tank body 110, with an inlet and an outlet provided on the tank body 110; a filtration device 120, connected to the inlet and the outlet of the tank body 110, the water in the tank body 110 can flow into the filtration device 120 through the outlet of the tank body 110, and the filtration device 120 can perform filtration treatment on the inflowing water; a circulation device, the circulation device is connected to the tank body 110 and the filtration device 120 to realize the water flow exchange between the tank body 110 and the filtration device 120 through the operation of the circulation device; a water quality intelligent control device 160, connected to the filtration device 120 and the circulation device, and the water quality intelligent control device 160 can control the operation of the filtration device 120 and the circulation device.

[0048] The fish tank water quality adjustment device 100 provided by an embodiment of the present invention includes a tank body 110, a filtering device 120, a circulation device, and a water quality intelligent control device 160. Among them, the filtering device 120 is connected to an inlet and an outlet provided on the tank body 110. The water in the tank body 110 can enter the filtering device 120 through the outlet. After the water is filtered by the filtering device 120, through the operation of the circulation device, the filtered water is pumped back into the tank body 110 from the filtering device 120, realizing the circulation of water between the tank body 110 and the filtering device 120, and further forming a 24-hour physical and biochemical circulation filtration. Further, the water quality intelligent control device 160 is connected to the filtering device 120 and the circulation device, and can control the operation of the filtering device 120 and the circulation device, realizing the intelligentization of the fish tank water quality adjustment device 100. The fish tank water quality adjustment device 100 of the present invention can realize artificial intelligence management with a relatively high degree of automation, does not require manual cleaning of the filter element 124 of the fish tank water quality adjustment device 100, does not require a large amount of working hours for water change, does not require fish farmers to have fish-raising knowledge, scientifically manages the fish tank through artificial intelligence, effectively ensures the stability of water quality, promotes the improvement of fish-raising ornamental value and convenience, and thus can play a great role in promoting the development of the aquarium industry.

[0049] It should be noted that, as Figure 1 and Figure 2 shown, the fish tank water quality adjustment device 100 provided by the embodiment of the present invention can collect information of the ornamental fish in the fish tank through the water quality intelligent control device 160. After artificial intelligence analysis and processing, the working system of the fish tank is determined, and the corresponding electrical appliances are started through the program control circuit, truly realizing the maintenance-free and intelligent management of the fish tank. The working principle mainly includes three parts: artificial intelligence generating the working system, the system program running in a loop, and big data information feedback, which are specifically described as follows:

[0050] First, in the process of artificial intelligence generating the working system, the water quality intelligent control device 160 can be connected to a computer and a mobile phone through a WIFI module and a cloud server. For example, when a user buys a fish tank and starts raising fish, it is necessary to identify and connect the device through the APP, and complete the information settings such as the variety, age, density, and fish tank size of the ornamental fish in the settings. After the water quality intelligent control device 160 collects the information, through artificial intelligence algorithm identification and processing with the built-in big data of the original ecological living habits of the ornamental fish, the working system of this fish tank is determined: the power matching system of electrical equipment such as the circulation water pump 150 and the heating rod; the environmental condition system such as simulated sunlight illumination, water temperature, PH, ammonia nitrogen, and nitrite; determining the cleaning system of the filter element 124 and the periodic water change system; determining the scientific diet system. For example, the water quality intelligent control device 160 can specifically be a central brain integrated circuit.

[0051] Specifically, the intelligent water quality control device 160 includes a remote communication module, a central brain, a cloud server, a program control device, a remote control, and a user terminal device, which are connected to control each electrical unit of the fish tank;

[0052] The remote communication module uses a WI-FI module and accesses the Internet through Beidou satellites, GPRS, 4G / 5G networks, etc. to upload to the cloud server, and then sends it to the user terminal device through the cloud server.

[0053] The user terminal device includes devices such as a background computer, a tablet computer, a mobile phone, etc., and software such as an APP connected to the cloud server.

[0054] The central brain can communicate through wifi, local area network or Bluetooth receiver to connect to each electrical unit of the fish tank (such as a thermostat, a lighting lamp, a camera, a feeder, a bacteria supplementer, a sterilization lamp, these electrical products are relatively common on the market) and the program control device, and set the working system adjustment through an embedded development program to achieve two-way feedback of instructions and information.

[0055] For example, store information commands in advance according to the living environment conditions of various ornamental fish. When the user sets the type of ornamental fish raised through the user terminal device such as a mobile phone APP, the central processor will command each electrical unit of the fish tank and the program control device to make appropriate working parameter adjustments, achieving suitable temperature, suitable lighting, suitable feces cleaning and separation system, and regular periodic water change and regular bacteria supplement working system, so as to realize artificial intelligence for maintaining ornamental fish.

[0056] The program control device includes a built-in communication module, a program control circuit, and an infrared receiver;

[0057] The built-in communication module of the program control device can be a WIFI communication module or Bluetooth, connecting to the central brain for two-way feedback of command information;

[0058] The built-in program control circuit of the program control device is connected to electrical units such as a sewage pump in the washing bin, a drainage pump in the sedimentation bin, a circulation water pump, a water replenishment solenoid valve, a washing motor, a high-level sensor, and a low-level sensor. Through parameter setting, it realizes the free switching between the circulation filtration mode and the washing and sewage discharge mode;

[0059] The built-in infrared receiver of the program control device is connected to the infrared transmitter of the remote control. Commands are sent to the transmitting program control circuit through the built-in program of the remote control to realize the free switching between the circulation filtration mode and the washing and sewage discharge mode.

[0060] Second, during the cyclic operation of the system program, the user can set the artificial intelligence hosting mode to run. The water quality intelligent control device 160 sequentially starts the physical and biochemical cyclic filtration mode and the sewage separation self-cleaning mode, and works in a cyclic manner, thereby achieving the purpose of fish tank maintenance-free. Specifically, in the case of the physical and biochemical cyclic filtration mode of the fish tank, the fish tank can be in a state of 24-hour water flow cyclic operation, ensuring that the water quality is filtered and purified; it can achieve automatic water replenishment to prevent the circulation water pump 150 from running dry due to water shortage; it can achieve regular discharge of sediment garbage and small-dose supplementary water change, avoiding water quality fluctuations and ensuring water quality stability. Further, according to the system program set in the artificial intelligence hosting mode, the physical and biochemical cyclic filtration mode runs and is timed to switch to the sewage separation self-cleaning mode. In the sewage separation self-cleaning mode, the fish tank can achieve automatic cleaning of the filter cotton and sewage discharge; automatically replenish new water to complete small-dose water change in a cycle. Further, the regular water change of the fish tank is assisted in the process of the physical and biochemical cyclic filtration mode. During the process of the physical and biochemical cyclic filtration mode, various reasons require water replenishment: due to the evaporation of the fish tank water, the liquid level in the biochemical bin 129 of the fish tank drops, and water replenishment is required; during the circulation process, a sediment drainage pump 133 is provided at the bottom of the sedimentation tank 121, and the bottom sediment is regularly sucked according to the program setting. Each sewage discharge will cause the water level in the biochemical bin 129 to drop, and water replenishment is required at this time.

[0061] Third, during the operation of big data information feedback, when the fish tank operates regularly with the water quality intelligent control device 160, the working states of each electrical appliance and various data of the fish tank will be timely fed back to the cloud server through the water quality intelligent control device 160, and the cloud server will transmit them to the computer terminal and the mobile terminal for service personnel to monitor and grasp.

[0062] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, the filtering device 120 includes: a sedimentation tank 121, which is connected to the outlet of the cylinder body 110, and the water in the cylinder body 110 can flow into the sedimentation tank 121; a washing bin 122; a water collecting box 123, which is arranged in the washing bin 122, the water collecting box 123 is located in the upper part of the washing bin 122, the water collecting box 123 is clamped and connected to the inner wall of the washing bin 122, and a water outlet is provided at the center of the water collecting box 123; a filter element 124, which is arranged in the washing bin 122, the filter element 124 is communicated with the water collecting box 123, and the water flowing out of the water outlet of the water collecting box 123 is filtered through the filter element 124.

[0063] In this embodiment, the filtering device 120 is further defined to include a sedimentation tank 121, a washing bin 122, a water collection box 123, and a filter element 124. Among them, the sedimentation tank 121 is connected to the outlet of the cylinder block 110. After the cylinder block 110 and the filtering device 120 are filled with water, the circulation device starts pumping water, and injects the filtered water in the filtering device 120 into the cylinder block 110. After the liquid level in the cylinder block 110 rises, it flows into the sedimentation tank 121 of the filtering device 120 through the outlet, and primary separation is completed in the sedimentation tank 121. The feces and residual bait with a larger specific gravity settle at the bottom of the sedimentation tank 121, and the sewage with a smaller specific gravity flows into the water collection box 123. It can be understood that because the water body of the sedimentation tank 121 is large, the water inflow speed from the fish tank is reduced, and the feces and residual bait with a larger specific gravity naturally settle at the bottom. Further, the water collection box 123 is arranged in the washing bin 122. Specifically, steps can be provided on the inner wall of the washing bin 122, and the water collection box 123 is installed at the steps on the inner wall of the washing bin 122 through a card slot to achieve the clamping connection between the water collection box 123 and the washing bin 122. Further, the outer end surface of the bottom of the water collection box 123 is a plane, which is convenient for realizing the connection between the water collection box 123 and the washing bin 122. A water outlet is provided at the center of the water collection box 123, and the water returned from the cylinder block 110 flows into the filter element 124 through the water outlet, and the water returned from the cylinder block 110 is filtered through the filter element 124.

[0064] In an embodiment of the present invention, as Figure 3 , Figure 4 and Figure 5 shown, the filter element 124 includes: a cotton core body 125, and the cotton core body 125 is in a plate shape, or a bowl shape with an upward opening, or a barrel shape with an upward opening; a buoyancy ring 126, which is arranged at the upper edge of the cotton core body 125.

[0065] In this embodiment, it is specifically described that the filter element 124 includes a cotton core body 125 and a buoyancy ring 126. The cotton core body 125 is composed of a composite material. For example, it is composed of a cotton and linen fiber filter cotton board and formed into a plate shape, a bowl shape or a barrel shape. The buoyancy ring 126 is arranged at the upper edge of the barrel shape, bowl shape or plate shape of the cotton core body 125. The combined filter element 124 has upward buoyancy and restoring force. After being washed and kneaded by the washing device 134, the mouth of the filter element 124 still remains upward, and as the water surface rises, it approaches the bottom of the water collecting box 123. The mouth of the filter element 124 is aligned with the water outlet in the center of the water collecting box 123. In order to prevent the filter element 124 from curling and overlapping during the washing and kneading process, an appropriate weight or a support block can be provided in the center of the filter element 124. Further, the water outlet of the water collecting box 123 can be tubular or have countless dense pores dispersed, corresponding to the appropriate shape of the filter element 124. If the filter element 124 is plate-shaped or bowl-shaped, it can correspond to a water outlet with countless dense pores scattered. If the filter element 124 is barrel-shaped, it can correspond to a tubular water outlet. Preferably, the water outlet is tubular, and the corresponding filter element 124 is of a barrel structure, and an appropriate weight is provided at the midpoint of the bottom of the barrel of the filter element 124, so that it can be ensured that the filter element 124 can stand upright after being impacted by water flow, washed and kneaded, and the barrel mouth floats upward on the water surface. As the water surface rises, the barrel mouth approaches the bottom of the water collecting box 123 and is aligned with the water outlet.

[0066] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a guide ring 127, which is arranged in the washing bin 122. The guide ring 127 is configured as a bowl shape with both ends open. The two open ends of the guide ring 127 are of different sizes. The small open end of the guide ring 127 faces upward and fits with the bottom of the water collecting box 123, and the large open end of the guide ring 127 is connected to the inner wall of the washing bin 122.

[0067] In this embodiment, a guide ring 127 is also arranged in the washing bin 122. The guide ring 127 is configured as a barrel structure similar to a bottomless bowl, with the small head facing upward and closely attached to the bottom plane of the water collecting box 123. The large open end of the guide ring 127 is connected to the inner wall of the washing bin 122. For example, the large open end of the guide ring 127 is seated on the inner wall slot of the washing bin 122 and is hermetically connected to the inner wall of the washing bin 122. The guide ring 127 can play a role in straightening the filter element 124, so that it can be ensured that after being impacted by water flow, washed and kneaded, the filter element 124 can stand upright under the straightening action of the guide ring 127, and the barrel mouth floats upward on the water surface. As the water surface rises, the barrel mouth approaches the bottom of the water collecting box 123 and is aligned with the water outlet.

[0068] Optionally, the water collection box 123 and the guide ring 127 are of an integral structure. It mainly plays a role in guiding and straightening. The filtered water flows from the washing bin 122 to the biochemical bin 129.

[0069] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a flow channel provided on the guide ring 127, and the water in the washing bin 122 flows out through the flow channel after passing through the filter element 124; a biochemical bin 129, the biochemical bin 129 is connected to the guide ring 127 through the flow channel, and the biochemical bin 129 is connected to the cylinder body 110.

[0070] In this embodiment, a flow channel is provided on the guide ring 127. For example, the flow channel is provided at the waist of the guide ring 127. After the fine particles in the fish tank water are physically intercepted and filtered by the filter element 124, the purified water seeps out from the pores of the filter element 124 and flows to the biochemical bin 129 through the flow channel at the waist of the guide ring 127, and is injected into the cylinder body 110 through the circulation water pump 150 in the biochemical bin 129, forming a 24-hour physical and biochemical circulation filtration.

[0071] As Figure 1 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a bacteria house 130 provided in the biochemical bin 129.

[0072] In this embodiment, a bacteria house 130 made of a porous material for breeding bacteria is provided in the biochemical bin 129, which can enable the bacteria to reproduce and form a nitrifying flora. The water passing through the filter element 124 flows through the flora in the biochemical bin 129 for a biochemical reaction, and the toxic substances such as ammonia nitrogen and nitrite in the water are degraded and neutralized. The biochemical bin 129 and the washing bin 122 are an integral whole, and the biochemical bin 129 and the washing bin 122 cooperate to realize the filtration of the water in the fish tank and the degradation and neutralization of toxic substances, so that the water quality after being treated by the fish tank water quality adjustment device 100 can continue to be used for raising fish.

[0073] As Figure 1 shown, in an embodiment of the present invention, the number of the biochemical bins 129 is multiple, and the multiple biochemical bins 129 are connected in series; the circulation device includes: a circulation water pump 150, the circulation water pump 150 is provided in the last-stage biochemical bin 129 among the multiple biochemical bins 129, the circulation water pump 150 is connected to the inlet of the cylinder body 110, and the circulation water pump 150 is connected to the water quality intelligent control device 160.

[0074] In this embodiment, multiple biochemical chambers can be designed according to the size of the water body in the fish tank. For example, a split-type biochemical chamber 129 is added. The multiple biochemical chambers 129 are connected in series through a pipe manifold. The circulation water pump 150 is placed in the last-stage biochemical chamber 129 and connected to the inlet of the cylinder body 110. The circulation water pump 150 is connected to the water quality intelligent control device 160. The water quality intelligent control device 160 can control the operation of the circulation water pump 150 to realize the transportation of the water in the biochemical chamber to the cylinder body 110, thereby realizing the regular automatic replenishment and replacement of water in the cylinder body 110 to ensure that the water in the cylinder body 110 is suitable for fish survival.

[0075] As Figure 2 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a downpipe manifold 131; a washing sewage pump 132 disposed in the washing chamber 122, the washing sewage pump 132 is connected to the water quality intelligent control device 160, and the washing sewage pump 132 can extract the sewage in the washing chamber 122 to the downpipe manifold 131; a sediment sewage pump 133 disposed in the sedimentation tank 121, the sediment sewage pump 133 is connected to the water quality intelligent control device 160, and the sediment sewage pump 133 can extract the sewage in the sedimentation tank 121 to the downpipe manifold 131.

[0076] In this embodiment, the fish tank water quality adjustment device 100 further includes a downpipe manifold 131, a washing sewage pump 132, and a sediment sewage pump 133. During the circulation process, since the feces and residual bait with a large specific gravity settle at the bottom of the sedimentation tank 121, in order to ensure the water quality, it is necessary to clean this part of the dirt. Therefore, a sediment sewage pump 133 is provided in the sedimentation tank 121 to regularly extract the sediment at the bottom of the sedimentation tank 121 according to the program setting of the water quality intelligent control device 160, and extract the sewage and sediment to the downpipe manifold 131, and then discharge it through the downpipe connected to the downpipe manifold 131 to realize automatic sewage discharge.

[0077] Furthermore, a washing sewage pump 132 is provided in the washing chamber 122 for discharging sewage from the washing chamber 122 after the washing filter element 124. Specifically, when the cleaning of the filter element 124 is completed, the washing sewage pump 132 at the bottom of the washing chamber 122 is started to discharge the sewage to the downpipe manifold 131, and then discharged through the downpipe connected to the downpipe manifold 131 to realize automatic sewage discharge.

[0078] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a washing device 134 connected to the water quality intelligent control device 160, the washing device 134 is disposed in the washing chamber 122 and connected to the filter element 124, and the washing device 134 can clean the filter element 124.

[0079] In this embodiment, a washing device 134 is further provided in the washing bin 122, and the washing device 134 can clean the filter element 124. For example, the washing power can be used to create water flow in the water body by means of water pump flushing, rotation of the agitator 136, etc. The washing device 134 of the present invention preferably uses the triangular motor 135 of a washing machine as the power, and is connected to the agitator 136 at the bottom of the washing bin 122 through a speed reducer 137. The motor 135 drives the agitator 136 to create water flow in the water body, so that the filter element 124 is stirred with the water flow, and the dirt is separated from the filter element 124 under the action of centrifugal force and eddy current. Further, in order to dehydrate the filter element 124, the washing power can be selected as the power structure of a fully automatic agitator 136 washing machine, and a dehydration inner barrel and a clutch are added to the washing bin 122. The agitator 136 and the motor 135 form a dehydration structure, and the inner barrel is driven to rotate by the program circuit and the holding spring to achieve dehydration.

[0080] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a makeup water solenoid valve 138, connected to the water quality intelligent control device 160, and the makeup water solenoid valve 138 is arranged on the pipeline communicating with the inlet of the cylinder body 110; a low-level sensor 139 of the washing bin, arranged in the washing bin 122 and connected to the water quality intelligent control device 160. When the low-level sensor 139 of the washing bin sends a signal, the water quality intelligent control device 160 can control the circulation water pump 150 and the makeup water solenoid valve 138 to start working; a high-level sensor 140 of the washing bin, arranged in the washing bin 122 and connected to the water quality intelligent control device 160. When the high-level sensor 140 of the washing bin sends a signal, the water quality intelligent control device 160 can control the circulation water pump 150 and the makeup water solenoid valve 138 to stop working.

[0081] In this embodiment, in order to better implement the function of sewage separation and self-cleaning of the fish tank, after automatically cleaning the filter element 124, it is also possible to automatically supplement new water to complete small-dose periodic water change. The fish tank filtration device 120 further includes a water replenishing solenoid valve 138, a low-level sensor 139 of the washing bin, and a high-level sensor 140 of the washing bin. Specifically, after the filter element 124 is cleaned, the washing and sewage discharge pump 132 at the bottom of the washing bin 122 is started to discharge sewage to the sewer manifold 131. After the sewage is emptied, the low-level sensor 139 of the washing bin at the bottom of the washing bin 122 sends a signal, and the water quality intelligent control device 160 sequentially starts the water replenishing solenoid valve 138, and the circulation water pump 150 operates. The water in the biochemical bin 129 is sucked by the circulation water pump 150 and injected into the washing bin 122 through the water replenishing solenoid valve 138. When the liquid level reaches the high water level, the high-level sensor 140 of the washing bin cuts off the circuit, and the water replenishment of the washing bin 122 is completed. At this time, if secondary washing is required, the water quality intelligent control device 160 sequentially starts the procedures of washing, sewage discharge, and water replenishment. After the set automatic washing program is completed, the system program automatically switches to the circulating physical and biochemical filtration mode for periodic circulation.

[0082] It can be understood that during actual use, the water in the cylinder body 110 also needs to be replenished due to reasons such as evaporation. Moreover, each sewage discharge will cause the water level in the biochemical bin 129 to drop, and at this time, water replenishment is also required.

[0083] As Figure 1 shown, in an embodiment of the present invention, the fish tank water quality adjustment device 100 further includes: a standby water tank 141, which is connected to the filtration device 120; a water inlet, which is arranged on the standby water tank 141; a partition 142, which is arranged in the standby water tank 141, and the partition 142 can isolate the space in the standby water tank 141 into multiple independent sub-spaces.

[0084] In this embodiment, the fish tank water quality adjustment device 100 is equipped with a standby water tank 141. The standby water tank 141 can be separately arranged from the filtration device 120 or integrated into a whole. From the perspective of easy handling, in a preferred embodiment of the present invention, the filtration device 120 and the standby water tank 141 are placed separately. The standby water tank 141 is provided with a water inlet and a partition 142. The water inlet is connected to the tap water pipeline by a first float valve switch 143 to ensure the liquid level of the standby water tank 141. A plurality of partitions 142 are arranged in the middle of the standby water tank 141 to isolate the space in the standby water tank 141 into multiple independent sub-spaces, which are respectively used to store fresh water and aged water that has been sun-dried. The bottom of the standby water tank 141 is connected to the biochemical tank 129 through a second float valve switch 144. When the liquid level in the biochemical tank 129 drops, the second float valve switch 144 in the biochemical tank 129 drops with the liquid level, and the water supply switch is opened. The water in the standby water tank 141 sequentially displaces along the partition 142 into the biochemical tank 129. When the liquid level in the biochemical tank 129 rises to a certain height, the second float valve switch 144 rises with the liquid level to close, realizing the water replenishment work. At the same time, the water level of the standby water tank 141 drops, and the first float valve switch 143 drives the water replenishment switch to realize the injection of tap water, and fresh water displaces aged water along the partition 142 into the biochemical tank 129. After the water replenishment is completed, the first float valve switch 143 of the standby water tank 141 closes the water replenishment switch as the liquid level rises.

[0087] In this embodiment, the intelligent fish tank further includes an automatic feeding device connected to the water quality intelligent control device 160. After the water quality intelligent control device 160 generates a scientific diet system, fish hobbyist users can select an automatic feeding device with an automatic feeding function, and the user can set the dose per meal and the number of times of feeding per day to realize automatic feeding.

[0088] It can be understood that since feeder products with automatic feeding functions are already relatively common on the market, the present invention will not elaborate.
