Description

Technical Field

[0001] This application relates to the field of water supply equipment, specifically a nanobubble water supply device. Background Technology

[0002] Nanobubble water dispensers are advanced devices that utilize nanoscale bubble technology to treat water. Through a high-pressure dissolution and release system, gases (such as oxygen and hydrogen) are converted into nano-sized bubbles with a diameter of less than 200 nanometers and uniformly dispersed in the water. Nanobubble water dispensers are widely used in drinking water purification and other fields. Their advantages include high efficiency and energy saving, no chemical additives, effective removal of pollutants, and enhanced self-purification ability of water, making them a green and environmentally friendly new type of water treatment equipment.

[0003] Traditional nanobubble water dispensers typically include an electrolysis cell to purify water through electrolysis. This electrolysis cell is usually located within the dispenser's tank. Since the electrolysis cell requires electrical connections, this integrated design of the water tank and electrolysis cell poses a safety hazard if the electrolysis cell malfunctions, potentially leading to leaks or contamination of the water tank. Furthermore, having the electrolysis cell inside the tank makes cleaning and maintenance difficult. Utility Model Content

[0048] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] like Figure 1As shown, this embodiment provides a nanobubble water supply device, which has a filter assembly 10, a first water tank 40 and a water outlet module 60. The filter assembly 10, the first water tank 40 and the water outlet module 60 are connected in series through pipelines. The inlet end of the filter assembly 10 is used to connect to the water inlet pipeline 101 and filter the water source before delivering it to the first water tank 40. The water in the first water tank 40 is discharged through the water outlet module 60 for user use.

[0050] The filtration assembly 10 in this embodiment includes a primary filter 11 and an RO filter element 12. The input end of the primary filter 11 is connected to the inlet water pipe 101 for preliminary filtration of externally supplied water. The RO filter element 12 is connected to the output pipe of the primary filter 11 for further filtration of the pre-filtered water, thereby improving water quality. The output end of the RO filter element 12 is connected to the first water tank 40 via a pipe.

[0051] In one embodiment, the primary filter 11 can be a commonly used filtration device such as an activated carbon filter, a resin filter, or a ceramic filter. The RO filter 12 mentioned in this embodiment, also known as a reverse osmosis filter, is a core component of the reverse osmosis water purification system. It is mainly used to remove impurities, pollutants, and harmful substances from the water, producing high-quality pure water.

[0052] A first water pump 71 can also be installed in the pipeline of the filter assembly 10 to increase the inlet water pressure.

[0053] The nanobubble water supply device in this embodiment is equipped with a nanobubble generating device 30. One end of the nanobubble generating device 30 is connected to the input end of the first water tank 40 through a pipeline, and the other end is connected to the output end of the first water tank 40 through a pipeline. The nanobubble generating device 30 and the first water tank 40 are connected to form a loop. The nanobubble generating device 30 is used to generate finished water with nanobubbles.

[0054] The nanobubble generator 30, also known as a nanobubble cutter, is a device that efficiently prepares nanoscale bubbles (typically less than 200 nanometers in diameter) in liquids using physical or chemical methods. Its core principle is usually based on techniques such as fluid dynamics shearing, rapid release of dissolved gases under pressure, or cavitation effects. Through precisely designed microstructures or energy fields, macroscopic bubbles are broken down and compressed into nanoscale ultramicrobubbles. These devices are widely used in water treatment and other fields. The nanobubbles they generate, due to their ultra-long residence time, huge specific surface area, and special surface charge characteristics, can significantly improve gas-liquid mass transfer efficiency, catalytic reaction activity, and the adsorption capacity of target substances.

[0055] In one embodiment, the nanobubble generating device 30 employs a jet cutter, which generates micro- and nanobubbles by shearing the fluid.

[0056] Specifically, the jet cutter adopts a dual-chamber structure design. The shell consists of a first chamber and a second chamber connected by a connecting port. The inlet and outlet are connected to the two chambers respectively, forming a liquid flow channel. The jet cutter utilizes a linkage mechanism between its automated cutting component and its elastic movable component. The movable component, composed of elastic elements such as metal sheets, elastic diaphragms, or rubber / silicone rings, serves as the sidewall of the first chamber and is simultaneously connected to the cutting component that controls the opening and closing of the connecting port. When the pressure difference exceeds a set threshold, it achieves a dynamic cutting function to cut the gas-water mixture, thereby obtaining micro-nano bubble liquid.

[0057] The working principle of the jet cutter is as follows: After the gas-water mixture enters the first chamber through the inlet, pressure accumulates. When the pressure difference overcomes the elastic resistance of the moving components, the elastic element deforms, causing the cutting component to instantly open the connection port. The high-pressure mixture is dynamically broken up by the cutting component in the form of a high-speed jet, and the diameter of the cut bubbles can reach the nanometer level. This process achieves automatic opening and closing control through pressure self-feedback, eliminating the need for additional high-pressure equipment. It has advantages such as low energy consumption, compact equipment, and integrated design. The generated nanobubbles have more uniform particle size (deviation less than 50nm) and more concentrated distribution, improving gas dissolution efficiency, making it particularly suitable for small-scale household drinking water purification applications.

[0058] Of course, the nanobubble generating device 30 can also be other devices capable of preparing micro- and nanobubbles; this embodiment is not limited to only one.

[0059] The nanobubble water supply device in this embodiment is further provided with an electrolytic cell pipeline assembly 50, which is separately disposed from the first water tank 40. The input end of the electrolytic cell pipeline assembly 50 is connected to the output pipeline of the filter assembly 10, and the output end of the electrolytic cell pipeline assembly 50 is connected to the input pipeline of the nanobubble generating device 30 for inputting hydrogen into the nanobubble generating device 30, thereby realizing the preparation of micro-nanobubbles by the nanobubble generating device 30.

[0060] In this embodiment, the electrolytic cell pipeline assembly 50 is configured as a loop. The electrolytic cell pipeline assembly 50 includes an electrolytic cell body 51 and a second water tank 52. The electrolytic cell body 51 and the second water tank 52 are connected by pipelines to form a loop.

[0061] like Figure 1 As shown, the output end of the electrolyzer body 51 has a hydrogen output pipe 501, which is connected to the input pipe of the nanobubble generating device 30 to input hydrogen into the nanobubble generating device 30.

[0062] Since the electrolytic cell pipeline assembly 50 can produce hydrogen and oxygen, the hydrogen output pipeline 501 mentioned in this embodiment can also be an oxygen output pipeline, or it can have both a hydrogen output pipeline 501 and an oxygen output pipeline, thereby producing oxygen or producing oxygen-containing nanobubble liquid.

[0063] The second water tank 52 provides electrolyzed water to the electrolytic cell body 51. The inlet of the second water tank 52 is connected to the output pipe of the filter assembly 10 through a pipeline to supplement the water source.

[0064] In this embodiment, the second water tank 52 provides a water source for the electrolytic cell body 51. The independent arrangement of the second water tank 52 and the first water tank 40 allows the electrolytic cell module to be separated from the first water tank 40. Thus, the first water tank 40 serves as a water tank for direct drinking, and its water quality is not affected by the electrolytic cell module.

[0065] As we all know, electrolytic cell modules need to be connected to electricity. However, connecting electricity to a drinking water tank poses certain safety hazards. For example, leakage caused by circuit failure in the electrolytic cell can easily lead to a fire, or damage to the electrolytic cell can cause water pollution. Furthermore, when the electrolytic cell needs maintenance or replacement, its location in the drinking water tank will inevitably cause inconvenience in maintenance operations and make it difficult to guarantee water quality safety.

[0066] In this embodiment, by placing the electrolyzer pipeline assembly 50 outside the first water tank 40, it is possible to produce finished water with nanobubbles. At the same time, the independent setting of the electrolyzer pipeline assembly 50 avoids the safety hazards caused by leakage of the electrolyzer and the problem of water tank contamination caused by damage to the electrolyzer. Furthermore, the independent pipeline of the electrolyzer facilitates the maintenance and cleaning of the electrolyzer, improving the flexibility and practicality of the water supply device.

[0067] like Figure 1 As shown, in one embodiment, a water quality stabilizer 53 is provided on the input pipeline of the electrolytic cell body 51 to optimize the water quality entering the electrolytic cell body 51, thereby protecting the electrolytic cell body 51 and improving the electrolysis efficiency.

[0068] Specifically, the water quality stabilizer 53 can be a purifier or filter, etc., to filter and purify the water. In one embodiment, the water quality stabilizer 53 uses a purification resin to ensure the stability of the water quality inside the electrolyzer body 51.

[0069] like Figure 1 As shown, the output end of the first water tank 40 in this embodiment is divided into two branches. One branch is connected to the water outlet module 60 to provide drinking water to the user, and the other branch serves as the input pipeline of the nanobubble generator 30, which is connected to the inlet end of the nanobubble generator 30.

[0070] In this embodiment, the input pipeline of the nanobubble generating device 30 has an ejector 31, and the hydrogen output pipeline 501 is connected to the ejector 31. The ejector 31 mixes hydrogen into water and sends it to the nanobubble generating device 30.

[0071] In one embodiment, the ejector 31 employs a venturi tube to achieve directional flow of hydrogen. A second water pump 72 can be installed in the pipeline between the venturi tube and the nanobubble generating device 30 to further increase the inlet water pressure.

[0072] In this embodiment, the output pipeline of the nanobubble generating device 30 includes a finished water pipeline 301 and a residual gas water pipeline 302. One end of the finished water pipeline 301 is connected to the outlet of the nanobubble generating device 30, and the other end is connected to the first water tank 40. The finished water containing micro-nano bubbles generated by the nanobubble generating device 30 flows into the first water tank 40 through the finished water pipeline 301.

[0073] Furthermore, the output pipe of the filter assembly 10 is connected to the finished water pipe 301 to mix the purified water with the finished water and then introduce it into the first water tank 40. Of course, the output pipe of the filter assembly 10 can also be directly introduced into the first water tank 40.

[0074] In this embodiment, the residual gas-water pipeline 302 is connected at one end to the gas outlet of the nanobubble generator 30 and at the other end to the first water tank 40, so as to pass the residual gas in the nanobubble generator 30 into the first water tank 40. Since the residual gas inevitably contains water vapor, the residual gas containing water vapor is collectively referred to as residual gas-water.

[0075] In this embodiment, the first water tank 40 has a water inlet and an air inlet. The water inlet is connected to the finished water pipeline 301, and the air inlet is connected to the residual gas water pipeline 302. The air inlet is located in the upper region of the first water tank 40 so that the residual gas water can enter the top of the first water tank 40, minimizing mixing with the water in the first water tank 40. In this embodiment, the air inlet is positioned higher than the water inlet.

[0076] As a further improvement, in one embodiment, the output pipeline of the filter assembly 10 is connected to a connecting valve 20, that is, a three-way valve is provided on the output pipeline of the RO filter element 12. The three-way valve has a first interface, a second interface and a third interface. The first interface is connected to the output pipeline of the RO filter element 12; the second interface is connected to the inlet pipe of the first water tank 40; and the third interface is connected to the inlet pipe of the electrolytic cell pipeline assembly 50.

[0077] Of course, the connecting valve 20 can also be a four-way valve, with the extra valve port connected to the drain pipe 201 for sewage discharge.

[0078] In one embodiment, the connecting valve 20 has a first drain port, the RO filter element 12 has a second drain port, and the first and second drain ports are connected to the drain pipe 201.

[0079] In this embodiment, the connecting valve 20 can be a solenoid valve to achieve intelligent control of each valve.

[0080] like Figure 1 As shown, the water outlet module 60 in this embodiment includes a water outlet pipe 601 and a heating device 61 connected to the water outlet pipe 601. The heating device 61 is used to heat the finished water in the water outlet pipe 601 to provide hot water to the user.

[0081] A third water pump 73 can be installed on the water outlet pipe 601 to increase the water outlet pressure.

[0082] like Figures 2 to 5 As shown, the nanobubble water supply device provided in this embodiment has a housing 80. The aforementioned filter assembly 10, first water tank 40, nanobubble generating device 30, and electrolytic cell pipeline assembly 50 are all housed within the housing 80. The water outlet module 60 extends from inside the housing 80 to its surface. Several switches 81 are provided on the surface of the housing 80, and these switches 81 are electrically connected to the water outlet module 60, serving as the user's water connection point. Several valves 82 are provided on the side wall of the housing 80, and these valves 82 are respectively connected to the aforementioned pipelines to achieve pipeline disconnection control.

[0083] A control valve for the water inlet pipe 101 and the drain pipe 201 is provided on one side of the outer casing 80 for easy operation. In this embodiment, the first water tank 40 and the second water tank 52 are arranged side by side for easy management and to make full use of space. Acrylic columns are provided at the bottom of the first water tank 40 and the second water tank 52 for support, which increases the height of the two water tanks and improves the water pressure.

[0084] Please see Figures 3 to 5 To clearly and concisely illustrate the components inside the outer casing 80, the piping structure is omitted in the figure. The primary filter 11 and the RO filter element 12 are located on one side of the first water tank 40 and the second water tank 52. An arched mounting bracket is located on the other side of the first water tank 40 and the second water tank 52. Above the mounting bracket is a nanobubble generator 30 and several power supplies 90. Below the mounting bracket is an electrolytic cell body 51 and an ejector 31. In the figure, multiple water pumps are correspondingly located within the internal space of the outer casing 80 and are electrically connected to the power supplies 90. In this embodiment, the multiple components inside the outer casing 80 are rationally arranged to achieve internal integration of the water supply device, fully utilizing the internal space of the outer casing 80 and facilitating the miniaturization of the nanobubble water supply device.

[0085] In one embodiment, the surface of the outer casing 80 is also provided with a hydrogen supply interface (shown in the figure), which is connected to the hydrogen output pipeline 501. The hydrogen produced by the electrolyzer pipeline assembly 50 can be supplied to the outside through the hydrogen supply interface. In this way, the hydrogen produced by the electrolyzer pipeline assembly 50 can not only be used to produce nanobubble water, but the excess hydrogen can also be used or collected for other purposes, which improves the versatility and multifunctionality of the nanobubble water supply device.

[0086] For example, excess hydrogen can be used to recharge portable hydrogen fuel cell power banks, replace hydrogen cylinders in hydrogen bicycles, supply hydrogen to various household respirators, and supply hydrogen to various hydrogen appliances such as hydrogen eyeglasses, hydrogen mattresses, hydrogen toothbrushes, and hydrogen combs.

[0087] Similarly, the surface of the outer casing 80 may also be provided with an oxygen supply interface for connecting the aforementioned oxygen output pipeline to realize the collection or utilization of excess oxygen.
