DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Figure 1The structure of a microbubble generating device 10 provided according to an exemplary embodiment of the present invention is shown. The microbubble generating device 10 can be used in multiple links such as water intake, drainage, and filtration of clothing processing equipment, and can also be applied to other fields, which is not limited by the present invention.

[0047] like Figure 1 As shown, the microbubble generating device 10 includes a water inlet pipe, an air guide pipe 420, a jet pipe 200 and a bubble generating pipe 100. Among them, a mounting hole is provided on the pipe wall of the water inlet pipe, and the air guide pipe 420 is fixedly connected to the water inlet pipe through the mounting hole. The air inlet of the air guide pipe 420 is located outside the water inlet pipe, and the air outlet of the air guide pipe 420 is located inside the water inlet pipe, and the air outlet direction of the air outlet is consistent with the water inlet direction of the water inlet pipe. The jet pipe 200 is connected to the water outlet of the water inlet pipe, and the pipe diameter of the jet pipe 200 matches the pipe diameter of the water inlet pipe. The jet pipe 200 is provided with a jet nozzle 220 that gradually narrows along the water outlet direction, and the jet nozzle 220 is used to improve the solubility and water flow rate of the bubbles introduced by the air guide pipe 420 in water. The bubble tube 100 is connected to the jet tube 200 . A filter screen 120 is disposed in the bubble tube 100 . The filter screen 120 is used to separate the gas dissolved in the water to form microbubble water.

[0048] Through the above scheme, when water flows from the water inlet pipe Figure 1 When the air flows from the right side to the left side, a negative pressure will be generated at the air outlet of the air guide pipe 420 located in the water inlet pipe, referring to Figure 2 and Figure 3 , thereby introducing air from the outside of the water inlet pipe into the water inlet pipe through the air inlet of the air guide pipe 420, and the air will be mixed in the water during the flow of water, thereby generating bubbles in the water flow and increasing the solubility of air in the water flow. It can also speed up the water flow, because the kinetic energy of each unit length of the water flow is fixed during the flow of water, and when bubbles are mixed into the water, it is equivalent to reducing the density of this part of the water flow, thereby increasing the flow rate of the water flow and increasing the spray distance.

[0049] like Figure 4 As shown, when the water flows through the jet nozzle 220 in the jet tube 200, the jet nozzle 220 can compress the water flow and pressurize the water flow. While pressurizing, the gas solubility of the water will be further increased, and the air entering through the air guide tube 420, the bubbles that are not dissolved in the water, and the water will be pressurized, which will increase the amount of air dissolved in the water for a second time. After the jet tube 200 compresses the water flow, the outflowing water flow speed increases, and after passing through the filter 120 in the bubble tube 100, the passing water flow is blocked at multiple points, and the pressure drops sharply behind the blocking point, allowing the gas dissolved in the water to be released in the form of bubbles, thereby forming micro-bubble water.

[0050] In detail, after the water flows through the obstacle, the pressure behind the obstacle decreases, and the gas dissolved in water will quickly overflow. Due to the surface tension of water molecules, the water molecules surround the gas to form bubbles. In other words, the lower the pressure behind the obstacle is than before the obstacle, the more bubbles will overflow. In addition, the more gas dissolved in water, the more precipitation will occur, and the higher the pressure, the easier it is for the gas to dissolve in water. Therefore, the present invention uses the air guide tube 420 to introduce gas into the water inlet pipe, and allows the gas to naturally dissolve in water in a longer pipeline, and then pressurizes it through the jet tube 200 to allow more gas to dissolve in water. The pressurized water flow rate becomes faster, and after encountering the filter screen 120 in the bubble tube 100, the pressure difference on both sides of the filter screen 120 in the flow direction of the water flow is larger, making it easier for gas to overflow and generate bubbles.

[0051] When the water inlet pipe stops flowing, since the air inlet of the air guide pipe 420 is an open structure, connected to the atmosphere, and the water flow in the water inlet pipe does not change in flow direction and kinetic energy, it will continue to maintain the original state and flow forward. Therefore, under the action of atmospheric pressure, the water in the water inlet pipe will flow out quickly and will not accumulate in the water inlet pipe, avoiding the formation of scale deposition and affecting the effect of subsequent micro-bubble water production. Otherwise, if there is no air guide pipe 420 in the water inlet pipe, when the valve in the water inlet pipe is closed and the water inlet stops flowing, since the rear end of the water inlet pipe is closed, the water in the water inlet pipe will generate negative pressure at the rear when it flows forward again, so that the water flowing forward is restrained and cannot continue to flow forward. Due to the surface tension of water molecules and the small diameter of the water inlet pipe, it is difficult for air to enter from the bubble tube 100 at the end of the water inlet pipe to relieve the negative pressure. Therefore, the water accumulated inside cannot be discharged. Since the mesh of the filter screen 120 in the bubble tube 100 is small, the surface tension of water molecules is stronger, which is more unfavorable for air to enter.

[0052] The principle by which the microbubble generating device 10 provided by the present invention can avoid the generation of scale deposition is explained below.

[0053] Since tap water generally contains dissolved calcium and magnesium ions, the harder the water, the higher the calcium and magnesium ion content. When harder tap water is in an open and static state for a long time, the water will absorb carbon dioxide, sulfur dioxide and other gases in the air. Carbon dioxide and sulfur dioxide dissolve in water to produce carbonate and sulfate ions. Carbonate and sulfate ions react with calcium and magnesium ions to produce water-insoluble precipitates such as calcium carbonate, magnesium carbonate and calcium sulfate. These precipitates accumulate to form scale.

[0054] Therefore, to avoid the formation of scale, on the one hand, we can reduce the calcium and magnesium ions in the water, for example, we can use water softening solutions. On the other hand, we can reduce the carbon dioxide and sulfur dioxide that cause the calcium and magnesium ions to precipitate, which is more difficult. In addition, we can reduce the time for hard water to combine with carbon dioxide and sulfur dioxide, so that the water has dried before they combine and react chemically. At this time, even if white powder is precipitated, it is calcium chloride and magnesium chloride that are easily soluble in water, and it will be quickly washed away during the next flushing.

[0055] When the valve 500 upstream of the water inlet pipe is closed, the residual water in the water inlet pipe will stop flowing immediately. Since the water inlet pipe is relatively thin, affected by the surface tension between the filter and water and the atmospheric pressure, this part of water will remain in the water inlet pipe for a long time. The location of the bubbler pipe outlet is closest to the air and is most likely to absorb acidic gas, and scale is most likely to be deposited here. Over time, the filter will be blocked and bubbles cannot be sprayed out.

[0056] The present invention provides an air guide pipe 420 in the water inlet pipe, and the air outlet of the air guide pipe 420 is located inside the water inlet pipe, and the air outlet direction of the air outlet is consistent with the water inlet direction of the water inlet pipe. When the valve 500 is closed, the water in the water inlet pipe that has not flowed out continues to flow forward under the action of inertia. At this time, the gas will enter the water inlet pipe through the air inlet. Since there is no negative pressure restraint, the water in the pipeline will continue to flow downstream unimpeded under the action of inertia and / or gravity until it flows out of the filter 120.

[0057] As an example, Figure 2 As shown, for ease of manufacture and installation, the air guide tube 420 is in an inverted L-shape, and its air outlet section ( Figure 2 The horizontal section in the middle) is located at the axis of the water inlet pipe, and the air inlet section ( Figure 2 The vertical section in the water inlet pipe) passes through the mounting hole provided on the water inlet pipe wall and then opens to the air. Alternatively, the air inlet section may also be an inclined section.

[0058] In some embodiments, in order to prevent the water outlet from being blocked artificially or accidentally in extreme cases, and the water in the water inlet pipe from overflowing through the air inlet, the present invention connects a backflow prevention component 450 to the air outlet of the air guide pipe 420. It should be pointed out that when the microbubble generating device 10 is used, the air inlet of the air guide pipe 420 can be connected to a drainage pipeline, or when the air inlet is in a space that can drain water or store water, the above-mentioned backflow prevention component 450 may not be provided.

[0059] As an example, the anti-backflow assembly 450 includes a hard tube 451 of a certain length and an elastic hose 452. One end of the hard tube 451 is sleeved at the air outlet of the air guide tube 420; one end of the elastic hose 452 is clamped between the air outlet of the air guide tube 420 and the hard tube 451, and the other end is set as an elastic water outlet, and the elastic water outlet is located in the hard tube 451.

[0060] Specifically, the hard tube 451 and the elastic hose 452 are overlapped with the air outlet of the air duct 420, and the elastic hose 452 is firmly connected and arranged in the hard tube 451 by sleeve-connecting the hard tube 451 on the air outlet of the air duct 420. In this way, when the water in the water inlet pipe flows normally, the air entering will expand the flat part of the elastic hose 452 to allow air to pass through; and when the water in the water inlet pipe stops flowing, the increased pressure will compress the flat part, thereby preventing the water from flowing out through the air duct 420.

[0061] In some embodiments, Figure 1 As shown, the water inlet pipe includes a main water inlet pipe 300 and a joint pipe 400 detachably connected to the main water inlet pipe 300, and the mounting hole is provided on the joint pipe 400. Figure 2 In this way, the joint pipe 400 and the air guide pipe 420 can be modularized and used as an independent, highly reliable integral component. When in use, the air guide pipe 420 can be connected to the joint pipe 400 and then connected to the main water inlet pipe 300 as a whole.

[0062] In addition, in the pipeline where the integral component is needed, for example, when the main water inlet pipe 300 is directly connected to the tap valve 500 in the user's home, the main water inlet pipe 300 can be cut off, and then the integral component can be inserted into the cut ends of the pipe openings. For example, annular convex ribs 411 can be respectively provided on the outer walls of the two ends of the joint pipe 400, and the two ends of the joint pipe 400 are inserted into the main water inlet pipe 300 so that the pipe opening of the main water inlet pipe 300 exceeds the position of the annular convex ribs 411, and then the pipe clamp is used to tighten it to prevent it from loosening.

[0063] In some embodiments, a boss 412 is provided on the tube wall of the joint tube 400, the mounting hole is a stepped hole 4121, and the stepped hole 4121 passes through the boss 412; the air guide tube 420 is fastened to the boss 412, and a sealing gasket 430 is provided between the air guide tube 420 and the stepped hole 4121. In this way, the integral component consisting of the joint tube 400 and the air guide tube 420 can be conveniently manufactured and assembled in batches.

[0064] As an example, Figure 2 and Figure 3As shown, a truncated cone boss 412 is provided at the top of the connector pipe 400, a stepped hole 4121 is provided on the boss 412 and vertically penetrates the boss 412, and a sealing gasket 430 adapted thereto is provided in the stepped hole 4121, and the setting of the sealing gasket 430 can prevent liquid leakage at the interface. The inner diameter of the stepped hole 4121 increases step by step from the inside to the outside along the radial direction, so that the setting of the stepped hole 4121 can not only install the sealing gasket 430, but also facilitate the insertion of the curved air guide pipe 420 into the connector pipe 400 through this. It should be pointed out that when the air inlet section of the air guide pipe 420 is inclined, the above-mentioned stepped hole 4121 can also be adaptively set as an inclined stepped hole that obliquely penetrates the boss 412, or the stepped hole 4121 is still vertical but the diameter is enlarged, and the sealing gasket 430 is still installed vertically, but the vertical part of the air guide pipe 420 is changed to obliquely pass through the sealing gasket 4121.

[0065] In some embodiments, in order to position the installation of the air guide tube 420, a flange ring 421 can be set on the air inlet section of the air guide tube 420, and the height of the flange ring 421 should ensure that the height of the air outlet section of the air guide tube 420 is at the same height as the axis of the joint pipe 400. In order to ensure that the air outlet section of the air guide tube 420 is coaxial with the joint pipe 400, a plurality of through holes are set on the flange ring 421, and corresponding blind holes are set on the boss 412. After assembly and alignment, they can be fastened by screws 440 to ensure that the two will not loosen. In addition, this can also ensure that the two are always in a coaxial setting state. Since liquids have viscous resistance, the closer to the pipe wall, the greater the resistance, the slower the water flow, and conversely, the closer to the center of the pipe, the faster the water flow, so that the air guide efficiency can be maintained.

[0066] In some embodiments, Figure 4 As shown, the jet nozzle 220 can be manufactured integrally with the jet tube 200. The jet nozzle 220 is a nozzle with a smooth transition and gradually narrowing, which can pressurize and speed up the water flowing through it. The pressurization process can increase the solubility of gas in water. The higher the solubility of air in water, the easier it is to generate bubbles and more bubbles. After the accelerated water flow encounters a mesh obstruction structure such as the filter 120, the pressure drops sharply, which can precipitate more air and generate more bubbles. Both ends of the jet tube 200 are provided with a second threaded section 211 or other connection limiting structures, such as ribs or grooves, which are detachably connected to the outlet of the main water inlet pipe 300.

[0067] In some embodiments, the filter screen 120 is tilted in the bubble tube 100. As an example, the angle α between the filter screen 120 and the water flow direction of the bubble tube 100 is in the range of 5° to 60°. Preferably, α is in the range of 10° to 40°. Since the filter screen 120 is tilted, the area sprayed onto the filter screen 120 is increased, thereby generating more bubbles.

[0068] In some embodiments, the inner wall of the bubble tube 100 is circumferentially provided with a step groove 111 which is elliptical when viewed from its vertical direction, and the filter screen 120 is obliquely clamped on the step groove 111; the jet tube 200 is inserted into the bubble tube 100, and a limiter 130 is embedded between the end of the jet tube 200 and the filter screen 120.

[0069] Specifically, the bubble tube 100 is a straight tube, and an inclined step groove 111 is provided on the inner wall of the bubble tube 100 for limiting the installation of the elliptical filter 120, and a limiting member 130 for fixing the filter 120 is also provided in the step groove 111. As an example, the limiting member 130 is a limiting tube with a standard hollow cylinder at the upper part and an elliptical shape cut off at the lower part.

[0070] The inner diameter of the limiter 130 matches the maximum inner diameter of the jet tube 200 and the minimum inner diameter of the bubble tube 100, so that the water flow will not be blocked additionally. At the same time, a first threaded section 112 or other pipeline connection structure, such as a convex rib, a groove, a buckle and other structures, is provided on the top of the bubble tube 100 for detachable connection with the jet tube 200. The bubble tube 100 should match the connection structure of the jet tube 200. After the jet tube 200 and the bubble tube 100 are installed, the jet tube 200 presses tightly against the limiter 130 to indirectly fix the filter screen 120; the filter screen 120 is installed at a relatively large angle to prevent the silt particles from clogging and adhering to the filter screen 120, and can guide the silt particles to move to the lower angle.

[0071] Optionally, the filter screen 120 is provided with a sand discharge hole 121 at a downstream position along the water flow direction, which can discharge the silt collected there after being filtered by the filter screen 120. In addition, the filter screen 120 is tilted to increase the water flow area and generate more bubbles.

[0072] In addition, the present invention stipulates that the jet tube 200 is detachably connected to the main water inlet pipe 300, and the bubble tube 100 is detachably connected to the jet tube 200. Therefore, even if larger particles of mud and sand accumulate on the jet nozzle 220 or the filter 120, it is easy to disassemble the components of the microbubble generating device 10 for cleaning or replacement.

[0073] The exemplary embodiment of the present invention further provides a clothes treating apparatus, comprising the above-mentioned microbubble generating device 10, wherein the microbubble generating device 10 is, for example, disposed on a water inlet pipe and used to supply microbubble water into a detergent box to accelerate the dissolution of detergent or washing powder.

[0074] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
