The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of illustrating the present invention and are not to be construed as limiting the present invention.

The micro-nano bubble liquid generating system 100 according to the embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1, 7 and 8, the micro-nano bubble liquid generating system 100 according to the embodiment of the present invention includes an air dissolving device 1, a pump body 75, a first valve 73, a second valve 74, a first pipeline 8, a third valve 81, a second pipeline 9 and a fourth valve 91.

Wherein, be formed with mixing chamber 16 in the device 1 of dissolving gas, be formed with intake pipe 5, feed liquor pipe 7 and drain pipe 6 that are linked together with mixing chamber 16 on the device 1 of dissolving gas. Wherein the inlet pipe 7 can introduce liquid into the mixing chamber 16, the inlet pipe 5 can introduce gas into the mixing chamber 16, and the outlet pipe 6 can be used for leading out liquid to a water terminal.

Further, the pump body 75 is disposed on the liquid inlet pipe 7, and the pump body 75 can pressurize the entire micro-nano bubble liquid generation system 100 during operation.

Further, a second valve body 74 and a first valve body 73 are provided on the liquid inlet pipe 7. The pump body 75 is disposed between the second valve body 74 and the first valve body 73, further, the first valve body 73 is disposed on the liquid inlet side of the pump body 75, and the second valve body 74 is disposed on the liquid outlet side of the pump body 75. That is, the second valve body 74 is closer to the gas dissolving device 1 than the first valve body 73.

Further, a third valve body 81 is provided on the first pipe 8 to control the opening and closing of the first pipe 8. The first inlet end 82 of the first pipeline 8 is connected between the first valve body 73 and the pump body 75, and the first outlet end 83 of the first pipeline 8 is connected with the liquid outlet pipe 6.

Then, with the third valve 81 open and the second valve 74 closed, the liquid flowing through the first valve 73 can directly enter the liquid outlet pipe 6 through the first pipeline 8; with the first valve element 73 and the second valve element 74 open, the liquid flowing through the first valve element 73 can be discharged not only directly from the third valve element 81 to the outlet pipe 6, but also via the gas dissolving device 1 to the outlet pipe 6.

Still further, a fourth valve body 91 is provided on the second pipe 9 to control the opening and closing of the second pipe 9. The second inlet end 92 of the second pipeline 9 is connected between the pump body 75 and the second valve body 74, and the second outlet end 93 of the second pipeline 9 is connected to the outlet pipe 6 and located at the outlet side of the first outlet end 83. That is, the first liquid outlet 83 is closer to the air dissolving device 1 than the second liquid outlet 93, and when the liquid in the air dissolving device 1 flows into the liquid outlet pipe 6, the liquid can preferentially enter the first pipeline 8 from the first liquid outlet 83 under a specific flow path, so as to provide a reliable structural guarantee for liquid discharge and air intake of the air dissolving device 1.

When the first valve element 73 is opened, the third valve element 81 is closed and the fourth valve element 91 is opened, the liquid flowing through the pump body 75 can flow not only into the air dissolving device 1 through the second valve element 74, but also directly to the liquid outlet pipe 6 through the second pipeline 9. When the first valve 73 and the second valve 74 are both closed and the third valve 81 and the fourth valve 91 are both opened, the air dissolving device 1 can form a complete passage with the liquid outlet pipe 6, the first pipeline 8, the liquid inlet pipe 7 and the second pipeline 9, so that liquid drainage and air inlet of the air dissolving device 1 are realized in the operating state of the pump body 75.

With the above structure, the micro-nano bubble liquid generation system 100 according to the embodiment of the present invention can realize different liquid inlet forms and liquid outlet forms by changing states of different valve bodies, and can realize flexible and variable liquid outlet forms by cooperating with operation of the pump body 75.

As shown in fig. 2, when the first pipeline 8 and the second pipeline 9 are respectively communicated with the liquid inlet pipe 7 and the liquid outlet pipe 6, under the action of the pump body 75, the liquid in the mixing chamber 16 can be sequentially discharged from the liquid outlet pipe 6, the first pipeline 8, the liquid inlet pipe 7, the second pipeline 9 and the liquid outlet pipe 6, so that the pressure in the mixing chamber 16 is reduced, the air inlet pipe 5 enters air into the mixing chamber 16, a liquid outlet mode is realized, at this time, the original liquid in the mixing chamber 16 can be separately discharged from the liquid outlet pipe 6 to a water using terminal, and the water using terminal of the mixing chamber 16 still keeps a certain amount of water outlet in the air inlet process.

As shown in fig. 3 and 4, when feed liquor pipe 7 communicates mixing chamber 16, then can feed liquor fast in the mixing chamber 16 to make the liquid of mixing chamber 16 increase fast and the pressure boost, make the gas that gets into in the mixing chamber 16 can the rapid dissolution in liquid, realize mixing chamber 16's dissolved gas, and then drain pipe 6 can outwards discharge dissolved gas liquid, provides reliable guarantee for micro-nano bubble water for follow-up processing.

As shown in fig. 5 and 6, when the liquid inlet pipe 7 is communicated with the second pipeline 9, the rapid discharge of the bubble-free normal liquid can be realized.

When the liquid inlet pipe 7 is communicated with the first pipeline 8, the liquid inlet pipe 7 can be quickly discharged from the liquid outlet pipe 6 without passing through the pump body 75, for example, in a specific example, the liquid outlet pipe 6 can be always kept from being cut off by the flow path, and even in the process of supplementing air by the air dissolving device 1, the liquid outlet pipe does not need to be cut off.

In the micro-nano bubble liquid generating system 100 according to the embodiment of the present invention, the pump body 75 can be opened or closed in different flow paths. For example, when the air inlet pipe 5 in fig. 2 is used for introducing air into the mixing chamber 16, the pump 75 is opened to provide a certain power for discharging the liquid in the mixing chamber 16, so that the liquid in the mixing chamber 16 preferentially enters the first pipeline 8 from the first liquid outlet end 83 and is introduced into the second pipeline 9 by the action of the pump 75, and the liquid in the second pipeline 9 reenters the position of the liquid outlet pipe 6 closer to the water use terminal from the second liquid outlet end 93, so as to be output to the water use terminal through the liquid outlet pipe 6.

For example, in the case of the aforementioned fig. 3, when the liquid inlet pipe 7 is fed toward the mixing chamber 16, the pump body 75 is closed to feed the mixing chamber 16 normally; when the pump body 75 is opened, the mixing cavity 16 can enter a rapid pressurizing liquid inlet mode, and the liquid inlet efficiency in the mixing cavity 16 is improved. Therefore, the pump body 75 can be used as a liquid discharge pump and a booster pump of the system, and the operation efficiency of the system is improved.

It can be understood that, compared with the pressurized gas dissolving method in the prior art which needs a booster pump for pressurization, the micro-nano bubble liquid generating system 100 of the invention has simple structure and low cost; the whole body is modularized, the volume is small, the arrangement is compact, the device is convenient to use on small equipment, the occupied volume can be changed, different use scenes are met, the noise is low, and the vibration is small. Compared with the scheme that air inlet control needs to be carried out by an air pump in the prior art, the micro-nano bubble liquid generation system 100 can realize air inlet through the pressure difference between the mixing cavity 16 and the air inlet pipe 5 when the pump body 75 discharges liquid, can control pressurization liquid inlet, simplifies components and improves the air inlet and air dissolving efficiency of the mixing cavity 16. Compared with the scheme that the system is difficult and inconvenient to switch between the micro-nano bubble effluent and the common effluent in the prior art, the micro-nano bubble liquid generation system 100 can realize the quick switching between the micro-nano bubble effluent and the common effluent by adjusting the opening and closing of different valve bodies and the operation of the pump body 75, and the water use form of the water use terminal is flexible.

In the description of the invention, features defined as "first", "second", "third" and "fourth" may explicitly or implicitly include one or more of the features for distinguishing between the described features, whether sequential or not.

It should be noted that the liquid in the present invention refers to a liquid in which a certain gas is dissolved, or a heated liquid, or a tap water with a certain impurity and a relatively low temperature, or a purified water purified by a purification device, or a relatively pure water supplied from a living water tank, and the water inlet described in the present invention refers to a liquid inlet, and the water outlet refers to a liquid outlet, which should be understood widely, and should not be limited to the water described in the chemical field.

Optionally, the first valve body, the second valve body, the third valve body and the fourth valve body of the invention can be normally open valves or normally closed valves, and can also be simple electromagnetic valves as long as the corresponding pipelines can be controlled to be opened and closed.

In some embodiments of the present invention, as shown in fig. 1, 7 and 8, the micro-nano bubble liquid generating system 100 further includes a first one-way valve 62, the first one-way valve 62 is disposed on the liquid outlet pipe 6 between the first liquid outlet end 83 and the second liquid outlet end 93, and the first one-way valve 62 enables the liquid outlet pipe 6 to be in one-way conduction.

In these examples, the first one-way valve 62 allows the liquid in the outlet pipe 6 to flow only from the direction of the air dissolving device 1 to the direction of the second outlet end 93, but not in the opposite direction; alternatively, the first one-way valve 62 may allow the liquid in the outlet pipe 6 to flow only from the direction of the first outlet end 83 to the direction of the second outlet end 93, but not in the opposite direction. Then, in the process of air intake of the air dissolving device 1 shown in fig. 2, the pump body 75 only enables the liquid in the air dissolving device 1 to be sucked into the first pipeline 8 and discharged onto the liquid outlet pipe 6 through the second pipeline 9 in the process of operation, and the liquid discharged onto the liquid outlet pipe 6 cannot reversely flow to the first liquid outlet end 83 through the first check valve 62, so that the liquid in the mixing cavity 16 can be continuously discharged from the liquid outlet pipe 6 to the water use terminal in the process of operation of the pump body 75, and the water flow is prevented from forming dead circulation.

Of course, in other examples, the first check valve 62 may not be provided, and the distance between the second liquid outlet end 93 and the first liquid outlet end 83 may be increased, so as to dispose the second liquid outlet end 93 farther from the first liquid outlet end 83, and no matter how the pump body 75 operates, the liquid in the second pipeline 9 will not be pumped back into the first pipeline 8, and no dead circulation of the water flow when the mixing chamber 16 discharges and admits the liquid will be formed.

In some embodiments of the present invention, the mode of the mixing chamber 16 has an intake mode and a dissolved air mode, and the switching of the modes is achieved by changing the operating states of the first valve body 73, the second valve body 74, the third valve body 81, the fourth valve body 91, and the pump body 75.

In some examples, as shown in fig. 2, the first valve 73 and the second valve 74 are closed, and the liquid inlet pipe 7 is no longer supplied with liquid, and the gas dissolving device 1 is no longer supplied with liquid, but a certain amount of liquid is retained in the gas dissolving device 1. Further, the third valve 81 is opened to make the first pipeline 8 respectively communicate with the liquid inlet pipe 7 and the liquid outlet pipe 6; the fourth valve 91 is opened to make the second pipeline 9 communicate with the liquid inlet pipe 7 and the liquid outlet pipe 6 respectively, and at the same time, a part of the liquid inlet pipe 7 between the first liquid inlet end 82 and the second liquid inlet end 92 is communicated, and a part of the liquid outlet pipe 6 between the gas dissolving device 1 and the first liquid outlet end 83 is also communicated. When the pump body 75 operates, the pump body 75 provides power and discharges the liquid in the mixing cavity 16 from the liquid outlet pipe 6, the first pipeline 8, the liquid inlet pipe 7, the second pipeline 9 and the downstream of the liquid outlet pipe 6 in sequence, meanwhile, the liquid in the mixing cavity 16 is continuously reduced to reduce the pressure in the mixing cavity 16 with a certain volume, a pressure difference is formed between the mixing cavity 16 and the air inlet pipe 5, so that the gas in the air inlet pipe 5 can rapidly enter the mixing cavity 16, and finally the mixing cavity 16 is switched to an air inlet mode. In the air inlet mode, because the liquid outlet pipe 6 still discharges liquid, the water terminal does not stop flowing before the mixing cavity 16 finishes discharging liquid, and the water terminal can keep feeding water when the mixing cavity 16 admits air.

In some examples, as shown in fig. 3 and 4, at least when the first valve 73 is opened to allow the liquid inlet pipe 7 to be supplied with liquid, the second valve 74 is opened to allow the liquid to be supplied to the gas dissolving device 1, and the third valve 81 is closed to stop the liquid outlet of the first pipeline 8, the gas dissolving device 1 can be rapidly filled with liquid, so that the volume of the mixing chamber 16 with a certain volume is rapidly filled with liquid, so that the pressure in the mixing chamber 16 is sharply increased, the gas previously entering the mixing chamber 16 is dissolved in the liquid under high pressure, so that the mixing chamber 16 is switched from the gas inlet mode to the gas dissolving mode, and the liquid outlet pipe 6 can deliver a large amount of gas dissolving liquid outwards.

As shown in fig. 4, in the air dissolving mode, the pump 75 of the present invention is opened, and the pump 75 can further increase the liquid inlet flow rate or the liquid inlet pressure of the air dissolving device 1, thereby improving the air dissolving effect. In the example of fig. 4, the fourth valve body 91 is also kept closed, so that the liquid outlet pipe 6 outputs only the dissolved gas liquid.

As shown in fig. 6, in the air dissolving mode, the fourth valve body 91 is opened, and the liquid outlet pipe 6 at this time can output not only a large amount of air dissolving liquid but also ordinary bubble-free liquid to the outside, so that the water output of the liquid outlet pipe 6 is increased, and the requirement of the user for a large water output can be met. In these examples, the mixing chamber 16 may also be suitably replenished with a certain amount of liquid, which facilitates a constant flow of water at the end of the subsequent replenishment in the mixing chamber 16 and with a certain amount of liquid available for use.

In other examples, of course, the second valve body 74 and the fourth valve body 91 can be opened alternatively, so that on the premise that a certain amount of dissolved air liquid is in the air dissolving device 1, either the dissolved air liquid can be discharged outwards or the ordinary liquid can be directly discharged outwards, so that the output of the dissolved air liquid and the output of the ordinary bubble-free liquid can be switched efficiently and conveniently, and the water terminal can be used for realizing flexible water utilization.

In some examples, as shown in fig. 5, the second valve 74 is closed to stop the air dissolving device 1 from feeding liquid, the third valve 81 is closed to stop the first pipeline 8 from discharging liquid, the first valve 73 is opened to stop the liquid feeding pipe 7 from feeding liquid, the fourth valve 91 is opened to stop the second pipeline 9 from discharging liquid, and when the pump 75 is opened, the normal water pressurization fast water discharge without bubbles can be realized, and then the water using terminal can obtain a large amount of water without bubbles without discharging liquid through the air dissolving device 1, so that the flow path is saved, and the efficiency of the micro-nano bubble liquid generating system 100 when switching to the normal water mode is improved.

In some embodiments of the present invention, the micro-nano bubble liquid generating system 100 further includes a second one-way valve 51, and the second one-way valve 51 is disposed on the gas inlet pipe 5 to make the gas flow from the gas inlet pipe 5 to the mixing chamber 16 in one way. The gas in the mixing chamber 16 does not enter the inlet pipe 5 in the reverse direction from the second check valve 51, thereby ensuring that the pressure state in the mixing chamber 16 is controllable. Therefore, when the liquid inlet pipe 7 is used for feeding liquid to the mixing cavity 16, the pressure in the mixing cavity 16 can be stably and step-by-step improved, and the gas dissolving effect is ensured.

Optionally, as shown in fig. 7, the micro-nano bubble liquid generating system 100 further includes an inflator 52, the inflator 52 is disposed on the air inlet pipe 5, the inflator 52 is disposed on the air inlet side of the second one-way valve 51, and the inflator 52 may inflate the mixing chamber 16.

The inflator 52 is used for pumping air into the air dissolving device 1, and the air pressure pumped by the inflator 52 is greater than or equal to the pressure in the air dissolving device 1, so that the inflator 52 actively pumps the air into the mixing cavity 16, the air intake of the mixing cavity 16 is realized, and the air intake efficiency of the mixing cavity 16 is improved.

It will be appreciated that the use of the inflator 52 and pump body 75 of the present invention provides for more efficient intake of the mixing chamber 16. The pump body 75 is used for pumping liquid to reduce the pressure in the mixing cavity 16, and at the same time, the inflator 52 is actively operated to increase the pressure in the air inlet pipe 5, so that the pressure difference between the air pressure pumped by the inflator 52 and the pressure in the air dissolving device 1 is larger, the air inlet of the mixing cavity 16 is controlled more quickly, and the efficient air inlet of the mixing cavity 16 is easier to realize.

That is, in the left-right direction, the ratio between the width dimension of the mixing chamber 16 and the width dimension of the dissolved water chamber is in the range of one fifth to one, and when the ratio between the width dimension of the mixing chamber 16 and the width dimension of the dissolved water chamber is less than one fifth, the width dimension of the mixing chamber 16 in the left-right direction is small, and sufficient air bubbles cannot be generated in the mixing chamber 16 to mix, thereby affecting the bubble content of the dissolved water and the quality of the dissolved water; when the ratio between the width dimension of the mixing cavity 16 and the width dimension of the dissolved water cavity is greater than 1, the width dimension of the mixing cavity 16 in the left-right direction is large, the width dimension of the dissolved water cavity in the left-right direction is small, the air bubble mixed flow in the mixing cavity 16 is large, the water to be dissolved in the dissolved water cavity is small, and the air bubble mixed flow cannot be completely dissolved in the inlet water, so that the waste of resources is caused, and the requirement of a user for using the dissolved water is influenced.

As shown in fig. 9, in the left-right direction, the ratio of the width dimension of the mixing chamber 16 to the width dimension of the dissolved water chamber is in the range of one fifth to one, so that the water flow parallel to the partition 15 is prevented from impacting the partition 15 to influence the generation of air bubble mixed flow, when the water flow impacts to form the air bubble mixed flow, in the mixing chamber 16 with a relatively small space, the air bubbles in the air bubble mixed flow are denser, the micro-nano bubble content is more, and the quality of the micro-nano bubble water is improved. Therefore, the generated air bubbles are mixed and dissolved into the dissolved water sufficiently, the waste of resources is avoided, and the quality of the dissolved water is ensured.

Therefore, the sufficient content of micro-nano bubbles in the air bubble mixed flow is ensured, and the economical practicability of the air dissolving device 1 is improved.

In some embodiments, the ratio between the volume of the mixing chamber 16 and the volume of the dissolving water chamber is in the range of 1/4 to 1. When the ratio of the volume of the mixing cavity 16 to the volume of the dissolved water cavity is less than one fourth, the volume of the mixing cavity 16 is small, air bubbles generated in the mixing cavity 16 are insufficient in mixing, and the content of the bubbles in the dissolved air liquid cannot be guaranteed, so that the quality of the dissolved air liquid is reduced, and the user experience is influenced; when the ratio of the volume of the mixing cavity 16 to the volume of the dissolved water cavity is larger than one, the volume of the mixing cavity 16 is larger, the air bubbles in the mixing cavity 16 are mixed more, the liquid to be dissolved in the dissolved water cavity cannot be dissolved into the air bubbles as much as possible, the air bubbles are mixed more, and the waste of resources is caused.

In some specific examples, the ratio between the volume of the mixing chamber 16 and the volume of the dissolved water chamber may be: 1/4, 1/3, 1/2, 1, and so forth.

Optionally, the ratio between the volume of the mixing chamber 16 and the volume of the dissolving water chamber is 1/2. Therefore, the volume capacity of the dissolved water cavity is ensured to be enough for users to use, and the content of micro-nano bubbles in the air bubble mixed flow is ensured to be sufficient, so that the economical practicability of the air dissolving device 1 is improved.

In some embodiments, the ratio of the height dimension of the partition 15 in the up-down direction to the up-down dimension of the cross-section of the housing 14 at the location of the partition 15 is between 0.4 and 0.9. That is to say, the upper portion or the lower portion of baffle 15 and casing 14 separate to form and overflow the passageway, and when the ratio between the height dimension of baffle 15 in the up-down direction and the up-down direction dimension of casing 14 cross baffle 15 position department cross-section was less than 0.4, the air bubble mixed flow can only get into the dissolved water chamber through the through-hole 151 of baffle 15, and the air bubble mixed flow is less, and the air bubble mixed flow is incomplete, inhomogeneous with water, has reduced the content of micro-nano bubble in the micro-nano bubble water to the quality of micro-nano bubble water has been reduced.

When the ratio of the height dimension of the partition plate 15 in the up-down direction to the dimension of the shell 14 in the up-down direction of the cross section of the position where the partition plate 15 is located is larger than 0.9, the distance between the upper side of the partition plate 15 and the upper end of the shell 14 is larger, a large amount of air bubble mixed flow directly enters the dissolved water cavity from the mixing cavity 16 from the overflowing channel at the upper end of the partition plate 15, so that the air bubble mixed flow in the main cavity is not completely and uniformly mixed with water, the quantity of micro-nano bubbles in the micro-nano bubble water is reduced, and the quality of the micro-nano bubble water is reduced.

Therefore, the ratio of the height dimension of the partition plate 15 in the vertical direction to the dimension of the cross section of the shell 14 passing through the partition plate 15 in the vertical direction is 0.4-0.9, so that the mixing speed of the air bubble mixed flow and the water in the main cavity is accelerated, and the air bubble mixed flow and the water are fully mixed.

In a specific example, the ratio of the height dimension of the partition 15 in the up-down direction to the dimension of the cross section of the housing 14 at the position where the partition 15 passes is between 0.4 and 0.9: 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, etc.

Optionally, the ratio of the height dimension of the partition 15 in the vertical direction to the dimension of the cross section of the shell 14 passing through the partition 15 in the vertical direction is 0.4, so that the quality of the micro-nano bubble water is ensured, the mixing speed of the air bubble mixed flow and the water in the main cavity is increased, and the air bubble mixed flow and the water are mixed fully.
