Description

Technical Field

[0001] This invention specifically relates to an integrated solution preparation device suitable for use with multiple water sources and a method for preparing solutions based on the integrated solution preparation device, which can be used in particular to provide high-quality seawater for aquariums used for keeping marine life at home. Background Technology

[0002] As society continues to develop, people's demands for material life are also increasing. Currently, many families have a need to keep marine life, and marine aquariums are constantly developing and expanding. However, for families who do not live near the sea, the availability of seawater for keeping marine life has become a problem. Keeping marine life in marine aquariums requires high water quality. Chlorine ions and other trace elements contained in ordinary tap water can affect the water quality of marine aquariums, increasing the difficulty of keeping them.

[0003] The seawater used to keep marine life in aquariums generally needs to be prepared by adding sea salt to pure water. Pure water is water that has been filtered through an RO reverse osmosis membrane. The function of the RO reverse osmosis membrane is to allow only water molecules to pass through through a membrane with tiny pores, while filtering out other compounds, particles, metal ions, molecules, etc. The TDS of pure water is close to 0 when measured by a TDS tester. The specific concentration of seawater prepared by adding sea salt to pure water is crucial for aquariums used for keeping marine life at home.

[0004] Existing patents, such as 202410782132.8, disclose an automatic water changing system for a seawater tank. The system itself does not have the function of providing pure water and requires an external RO machine. It cannot be used in multi-water source environments, has limited applicability, and the overall system size is relatively large.

[0005] At the same time, there is a lack of miniaturized, integrated equipment in the existing technology that can prepare target solutions.

[0006] The above background information is provided only to aid in understanding the inventive concept and technical solution of this invention. It does not necessarily belong to the prior art of this invention. In the absence of clear evidence that the above information was disclosed before the filing date of this invention, the above background information should not be used to evaluate the novelty and inventiveness of this invention.

[0014] According to some preferred embodiments of the present invention, the preparation container is equipped with a preparation level sensor, and the volume of the preparation container corresponding to the preparation level sensor matches the volume corresponding to the default solution concentration of the integrated solution preparation device. A fixed amount of solvent is added each time by the solvent adder.

The lower limit liquid level sensor is positioned higher than the highest point of the second pump, heating assembly, temperature sensor, water flow generating assembly, and concentration detector, ensuring that the components are always submerged below the liquid level. The upper limit liquid level sensor is used to ensure safety, preventing water overflow and damage to the equipment caused by excessively low user-set concentrations requiring a large volume of pure water.

Preferably, a concentration detector is provided within the storage device for detecting whether the filtered pure water meets the standard, and can also output a filter replacement signal to ensure that the water entering the preparation container is pure water.

[0019] According to some preferred embodiments of the invention, a control device is included, which is electrically connected to and controls the operation of each device. The control device includes a control panel, the top surface of which is flush with the top surface of the solvent adder, so that the integrated solution preparation device is generally in the shape of a cuboid or cube, resulting in a simpler overall appearance while ensuring a sufficiently small space occupation, making it suitable for home use.

[0020] According to some preferred embodiments of the present invention, the pressureless water source interface and pressurized water source interface of the water supply device, and the pure water outlet interface and solution outlet interface of the water outlet device are respectively located at two opposite corners on the same surface of the housing, and the height of the pure water outlet interface and solution outlet interface is greater than the height of the pressureless water source interface and pressurized water source interface. The greater distance between the water source interface and the outlet interface allows for the addition of connecting pipes, enabling more components to be housed inside the equipment while maintaining a compact design and a small overall size.

[0021] The present invention also provides a solution preparation method based on the integrated solution preparation device described above, comprising the following steps: The unpressurized water source passes through the unpressurized water source interface, then through the first pump and the first valve, and enters the filtration device to produce pure water for storage; and / or, the pressurized water source passes through the pressurized water source interface, then through the first valve, and enters the filtration device to produce pure water for storage. Pure water is output from the storage device through the pure water outlet; and / or, pure water is output from the storage device to the preparation device, and after being prepared into a solution by the preparation device, it is output from the solution outlet.

[0022] According to some preferred embodiments of the present invention, when the user changes the solution concentration through the control system, i.e., when a target solution concentration needs to be prepared, the step further includes: setting the preparation concentration of the solution through the control device, wherein the concentration detector in the preparation container continuously detects the concentration of the solution in the preparation container; When the concentration of the solution in the preparation container reaches the set concentration, the concentration detector sends a stop signal to the control device.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] Example 1: Integrated solution preparation equipment for multiple water sources like Figure 1-5 As shown, the integrated solution preparation device for multiple water sources in this embodiment includes a housing 1, a water supply device, a filter device 3, a storage device 4, a preparation device 5, a water outlet device, and a control device disposed within the housing 1. The water supply device, filter device 3, storage device 4, and preparation device 5 are connected in sequence. The storage device 4 is located above the preparation container 51, and an overflow port is provided on the side of the storage device 4. The overflow port is connected to the upper end of the overflow pipe 42, and the lower end of the overflow pipe 42 extends into the interior of the preparation container 51. By placing the storage device 4 above the preparation container 51, pure water enters the preparation container 51 through the overflow port and the overflow pipe 42, eliminating the need for an additional power supply for water supply. Meanwhile, the water supply device and the filter device 3 are disposed on the side of the preparation container 51. Preferably, a reinforcing plate 8 is provided on the side of the preparation container 51, and the water supply device and the filter device 3 are fixed to the reinforcing plate 8 to strengthen the overall structural strength and further reduce the space required.

[0028] The water supply device is used to provide a water source, the filtration device 3 is used to filter the water source, the storage device 4 is used to store the pure water obtained by the filtration device 3, the preparation device 5 is used to prepare a solution using the pure water in the storage device 4, the water outlet device is connected to the storage device 4 to output pure water and to the preparation device 5 to output the prepared solution, and the control device is electrically connected to each device and controls the operation of each device.

[0029] The water supply device includes a pressureless water source interface 21 and a pressurized water source interface 22, a first pump 23, and a first valve 24. The pressureless water source interface 21 is connected to the first pump 23, and the first valve 24 is connected to the pressurized water source interface 22, the first pump 23, and the filter device 3. Preferably, the first pump 23 is a self-priming pump, which draws water and provides pressure to make the water flow through the filter device 3. The first valve 24 is a two-position three-way solenoid valve, with its inlet connected to both the first pump 23 and the pressurized water source interface 22.

[0030] The filtration device 3 includes a PP cotton filter assembly 31, an activated carbon filter assembly 32, and an RO reverse osmosis membrane filter assembly 33 connected in sequence. The PP cotton filter assembly 31 is connected to the first valve 24, and the RO reverse osmosis membrane filter assembly 33 is connected to the storage device 4. The PP cotton filter assembly 31 is used for coarse filtration of large particles, the activated carbon filter assembly 32 is used for filtration of small particles, and the RO reverse osmosis membrane filter assembly 33 is used for filtration of ions, thereby outputting pure water. The first valve 24 is connected to the bottom of the PP cotton filter assembly 31, the top of the PP cotton filter assembly 31 is connected to the top of the activated carbon filter assembly 32, the bottom of the activated carbon filter assembly 32 is connected to the bottom of the RO reverse osmosis membrane filter assembly 33, and the top of the RO reverse osmosis membrane filter assembly 33 is connected to the storage device 4. The connecting pipes between the PP cotton filter assembly 31, the activated carbon filter assembly 32, and the RO reverse osmosis membrane filter assembly 33, as well as some connecting pipes between the PP cotton filter assembly 31 and the first valve 24, and some connecting pipes between the RO reverse osmosis membrane filter assembly 33 and the storage device 4, are located on the same vertical plane, which is parallel to the reinforcing plate 8. This pipe arrangement optimizes the overall structure and reduces the volume occupied.

[0031] Preferably, such as Figure 2 and Figure 3 As shown, water is delivered to the bottom of the PP cotton filter assembly 31 through the first valve 24. After being filtered by the PP cotton filter assembly 31, water enters the activated carbon filter assembly 32 through its top and the top of the activated carbon filter assembly 32 for further filtration. Then, water passes through the bottom of the activated carbon filter assembly 32 and the bottom of the RO reverse osmosis membrane filter assembly 33 for further filtration. After being filtered by the RO reverse osmosis membrane filter assembly 33, pure water is output from the top of the RO reverse osmosis membrane filter assembly 33 to the storage device 4. Through this pipeline and sequence arrangement, the water achieves a high elevation during filtration and finally overflows into the preparation container 51 from the storage device 4. There is no need to use additional components or energy to actively deliver pure water from the storage device 4 to the preparation container 51, saving energy and space.

[0032] The water outlet device includes a pure water outlet 61 and a solution outlet 62. The pure water outlet 61 is connected to the storage device 4, and the solution outlet 62 is connected to the preparation device 5. The pressureless water source interface 21 and the pressurized water source interface 22 of the water supply device are located at two opposite corners on the same surface of the housing 1, respectively, and the heights of the pure water outlet 61 and the pressurized water source interface 62 are greater than the heights of the pressureless water source interface 21 and the pressurized water source interface 22. The greater distance between the water source interface and the outlet interface allows for the addition of connecting pipes, enabling more components to be installed inside the equipment while maintaining a compact design and a small overall size.

[0033] The preparation device 5 in this embodiment includes a preparation container 51, a solvent adder 52 located above the preparation container 51, a second pump 53 located inside the preparation container 51, a heating assembly 57, a temperature sensor 58, a water flow generating assembly 59, and a concentration detector 7. The solvent adder 52 is used to add liquids or solids corresponding to the target solution, such as salt. For example, if seawater needs to be prepared, the solvent is solid sea salt. The second pump 53, heating assembly 57, temperature sensor 58, water flow generating assembly 59, and concentration detector 7 are all located at the bottom of the preparation container 51 and are positioned corresponding to the solution outlet 62. The second pump 53 is connected to the solution outlet 62. The solvent adder 52 adds solvent to the preparation container 51 as needed, and after preparation, the prepared solution is output from the solution outlet 62 via the second pump 53. Heating component 57 and temperature sensor 58 control the liquid in preparation container 51 to maintain a certain temperature. Heating component 57 can be a heating rod. Water flow generating component 59 is used to increase the flow of water in preparation container 51, using a wavemaker, turbulence pump, or stirrer to increase the dissolution rate of solvents such as salts. Concentration detector 7 detects the concentration of the prepared solution, preferably a TDS detector. Preferably, baffles are provided on the inner wall of preparation container 51 to further increase the turbulence effect and accelerate solvent dissolution.

[0034] The preparation container 51 is equipped with a lower limit level sensor 54, a preparation level sensor 55, and an upper limit level sensor 56, arranged sequentially from bottom to top and on the same vertical line. The volume of the preparation container 51 corresponding to the preparation level sensor 55 matches the volume corresponding to the default solution concentration of the integrated solution preparation equipment. The solvent adder 52 adds a fixed amount of solvent each time. With the preparation level sensor 55 set, when pure water is added, a solution of the default concentration can be obtained with a fixed volume of pure water and a fixed amount of solvent. The lower limit level sensor 54 is positioned higher than the highest points of the second pump 53, heating assembly 57, temperature sensor 58, water flow generating assembly 59, and concentration detector 7, ensuring that these components are always submerged below the liquid level. The upper limit level sensor 56 ensures safety by preventing water overflow and damage to the equipment caused by an excessively low concentration requiring a large volume of pure water. When the water level reaches the upper limit level sensor 56, the equipment cuts off the water supply and power, triggers an alarm, and requires manual intervention.

[0035] The storage device 4 is equipped with a third pump 41, a concentration detector 7, and a pure water level sensor 43. The third pump 41 is connected to the pure water outlet 61. The concentration detector 7 and the third pump 41 are located at the bottom of the storage device 4. The concentration detector 7 is used to detect whether the filtered pure water meets the standard, and can also output a filter replacement signal to ensure that the water entering the preparation container 51 is pure water. The concentration detector 7 in the storage device 4 is preferably a TDS detector. The pure water level sensor 43 is positioned below the bottom of the overflow port, so that the pure water level in the storage device 4 is always maintained between the bottom of the overflow port and the pure water level sensor 43.

[0036] The control device includes a control panel 9, the top surface of which is flush with the top surface of the solvent adder 52, making the integrated solution preparation device a cuboid or cube shape. This design minimizes space requirements and results in a simpler overall appearance, suitable for home use. Preferably, the control device has cloud and local area network connectivity, allowing it to upload device operating data to a mobile device.

[0037] The control panel 9 in this embodiment has function buttons for self-priming, solution (seawater), pure water, filtration, temperature, concentration (salinity), and power. Corresponding to the function buttons on the control panel 9, the integrated solution preparation device has two water inlet methods: the default is tap water (with a pressurized water source). When the self-priming function button is activated, the self-priming pump (first pump 23) starts, allowing connection to a non-pressurized water source. After pressing the seawater function button, the second pump 53 starts, providing the prepared solution through the solution outlet 62. A long press of the solution function button switches the solution supply volume (e.g., 2L, 3L, 5L, 8L, 10L, 15L, 20L). After pressing the pure water function button, the third pump 41 starts, providing pure water through the pure water outlet 61. A long press of the pure water function button switches the pure water supply volume (e.g., 2L, 3L, 5L, 8L). The system has display boxes for filtration, temperature, and salinity. When the filtration display box is red, the PP cotton filter assembly 31 needs to be replaced; when it's yellow, the activated carbon filter assembly 32 needs to be replaced; and when it's purple, the RO reverse osmosis membrane filter assembly 33 needs to be replaced. The temperature display box shows the temperature; pressing and holding the temperature function button allows you to set the temperature. The salinity display box shows the salinity; pressing and holding the salinity function button allows you to set the salinity to output a solution of the set concentration. The power button controls the power switch.

[0038] Example 2 Solution Preparation Method The solution preparation method based on the above-described integrated solution preparation equipment in this embodiment includes the following steps: The unpressurized water source passes through the unpressurized water source interface 21, then through the first pump 23 and the first valve 24, and then enters the filter device 3 for filtration, producing pure water to the storage device 4; or, the pressurized water source passes through the pressurized water source interface 22, then through the first valve 24, and then enters the filter device 3 for filtration, producing pure water to the storage device 4. Pure water is output from storage device 4 through pure water outlet 61; or, pure water is output from storage device 4 to preparation device 5, and after being prepared into a solution by preparation device 5, it is output from solution outlet 62. At this time, the output solution is the default concentration corresponding to the amount of solvent added at one time and the volume of water in the liquid level sensor 55 at the preparation position.

[0039] When the user changes the solution concentration through the control system, i.e. when the target solution concentration needs to be prepared, the above steps also include: setting the solution preparation concentration through the control device, and the concentration detector 7 in the preparation container 51 continuously detecting the concentration of the solution in the preparation container 51; when the concentration of the solution in the preparation container 51 reaches the set solution preparation concentration, the concentration detector 7 sends a stop signal to the control device, the control device receives the stop signal and sends a shut-off signal to the first pump 23 and the first valve 24, so that the first pump 23 and the first valve 24 are shut off.

[0040] like Figure 6 As shown, the specific steps for preparing a target concentration solution, such as seawater, based on the above integrated solution preparation equipment are as follows: Step 1, Water Intake Pressurized water, such as tap water, enters the filter device 3 through the pressurized water source interface 22 and the three-way solenoid valve.

[0041] When the self-priming function button is pressed on the control panel 9, the first pump 23 (self-priming pump) is turned on, allowing access to a pressureless water source. When a pressureless water source is connected, the water is drawn in by the self-priming pump and then enters the filter device 3 through the three-way solenoid valve.

[0042] The first pump 23 (self-priming pump) is controlled to start and stop via the self-priming function button. When the self-priming function is activated, the pump starts working; otherwise, it is turned off. The self-priming pump can actively draw water and provide a pressure of at least 0.4 MPa to allow the water to pass through the filter device 3.

[0043] The first valve 24 is a three-way solenoid valve with two inlets and one outlet. The inlets are connected to the self-priming pump interface and the pressurized water source interface 22, respectively. The self-priming function button controls the switching: when self-priming is started, the inlet switches to the self-priming pump interface; when self-priming is stopped, it switches to the tap water interface. When both pressurized and unpressurized water sources are connected simultaneously, the equipment first uses the unpressurized water source. If the control device detects that the pure water level has not increased after the first pump 23 (self-priming pump) has supplied water for 10 seconds, meaning that the pure water level sensor 43 has not detected a water level, the control device assumes that the unpressurized water source is depleted and automatically switches to the pressurized water source.

[0044] As mentioned above, the position of the pure water level sensor 43 is lower than the bottom of the overflow port. Normally, the water level in the storage device 4 is at the bottom of the overflow port. After the third pump 41 in the storage device 4 starts to output pure water, the pure water level drops. When the pure water level sensor 43 does not sense water, the first valve 24 opens and water is injected into the storage device 4 by starting the filter device 3 until the pure water level sensor 43 is triggered to sense water again. This ensures that the water level in the storage device 4 is at the designated position, between the bottom of the overflow port and the pure water level sensor 43.

[0045] Step 2, Filtering The outlet of the three-way solenoid valve is connected to a PP cotton coarse filter assembly to filter large particles of impurities from the water source. Then, it is connected to an activated carbon filter assembly 32 to filter small particles of impurities. After that, it is connected to an RO reverse osmosis membrane filter assembly 33 to filter other ions, and outputs pure water to a pure water container (storage device 4).

[0046] Step 3: Pure water output Storage device 4 is equipped with a pure water supply pump (third pump 41), whose start-up and operating time can be controlled by a pure water function button. Storage device 4 has an overflow port and overflow pipe on one side. When the water level is higher than the overflow port, pure water flows into the preparation container 51 through the overflow port and overflow pipe. The pure water container is equipped with a level sensor, and the sensor detection position is lower than the overflow port, ensuring that there is water between the bottom of the overflow port and the pure water level sensor 43. As described in step 1, when the water level is lower than the pure water level sensor 43, the device automatically controls the self-priming pump to add water. The pure water container is equipped with a TDS detector to detect whether the filtered pure water meets the standard, and can also output a filter replacement signal to ensure that the water entering the preparation container 51 is pure water.

[0047] Step 4: Seawater preparation The following uses seawater as an example to illustrate the preparation process: An alarm will sound when the amount of sea salt is less than the preset value, prompting you to add sea salt. Each time a fixed amount of sea salt is added, it will be added to the preparation container 51.

[0048] Users can set the temperature and salinity using the function buttons on control panel 9 (the salinity is initially set to the standard seawater salinity).

[0049] Pure water flows into the seawater preparation container 51 through the overflow port and overflow pipe 42 of the pure water container. When the water level reaches the lower limit water level of the corresponding lower limit liquid level sensor 54, the solvent adder 52 automatically adds a fixed amount of sea salt, the water flow generating component 59 (wave generator) works, the heating rod works, the TDS detector continuously detects the salinity of the solution in the preparation container 51, and the temperature sensor 58 detects the temperature of the prepared solution. If it is lower than the set value, the heating rod is activated. At this time, the seawater function button displays red and seawater cannot be supplied.

[0050] As pure water is continuously injected, the sea salt is continuously dissolved. When the TDS detector detects that the salinity and temperature have reached the user's preset values, it sends feedback to the control device, which then stops the water supply, the water flow generator 59 stops working, the heating rod stops working, the preparation is complete, and the seawater indicator light indicates that seawater can be supplied.

[0051] If the water level triggers the preparation level sensor 55 during preparation but does not trigger the upper limit level sensor 56, it is normal and the original amount of solvent (sea salt) is maintained. If the water level reaches the upper limit corresponding to the upper limit level sensor 56 during preparation, the equipment will cut off the water supply and power supply, the equipment will alarm, and manual intervention will be required. The alarm will be lifted after the solution is discharged below the preparation level sensor 55 to prevent water from overflowing the preparation container 51.

[0052] If the user does not set the salinity through the function keys on the control panel 9, the solvent adder 52 adds a fixed amount of sea salt. When the water level in the preparation container 51 reaches the preparation level sensor 55, it feeds back to the control device, which then stops the water supply. This is the default concentration, i.e., the standard seawater salinity.

[0053] Figures 1 to 6 The use of the terms "seawater" or "sea salt" in some of the accompanying drawings is not intended to limit the scope of protection of this invention, but merely to illustrate the preparation of seawater in the embodiments. In practical applications, the device of this invention can be used to prepare other target solutions, such as other types of brine, etc., and the material of the device can be adapted to the corrosiveness of the target solution.

[0054] This invention relates to an integrated solution preparation device that can be used with multiple water sources. It incorporates a built-in filtration system with an RO reverse osmosis membrane filter assembly and can be configured with either a pressureless or pressurized water source interface depending on the situation. It can produce pure water or solutions of specific concentrations as needed, thus broadening its applicability. The integrated design is compact, space-saving, and aesthetically pleasing, making it suitable for home use. When used to prepare seawater, this integrated solution preparation device provides high-quality seawater to marine aquariums. It has the function of filtering water sources into pure water and can be connected to tap water or a pressureless water source (it is equipped with a high-pressure self-priming diaphragm pump). Simply connect the water pipe to the water source to prepare the required high-quality seawater. It can provide pure water to replenish water evaporated from the marine aquarium or provide high-quality seawater for water changes. This invention provides families with an intelligent seawater preparer and water filtration device that can prepare high-quality seawater, facilitating the preparation of seawater and providing pure water, reducing the difficulty of keeping marine life at home, and increasing the diversity of integrating nature and family life.
