Then, when the first valve 73 is opened, the third valve 81 is closed and the fourth valve 91 is opened, the liquid flowing through the pump body 75 can not only flow into the air dissolving device 1 through the second valve 74, but also flow 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, thereby realizing liquid drainage and air inlet of the air dissolving device 1 in the operating state of the pump body 75.

According to the structure, the utility model discloses micro-nano bubble liquid generation system 100 through the state that changes different valve bodies, can realize different feed liquor forms and play liquid form, and the operation of the deuterogamying pump body 75 can realize nimble changeable play liquid form.

As shown in fig. 2, when the first liquid outlet end 83 is closer to the gas dissolving device 1, 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 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 the mixing chamber 16, a liquid outlet mode is realized, the original liquid in the mixing chamber 16 can be separately discharged from the liquid outlet pipe 6 to a water terminal, and the water terminal of the mixing chamber 16 still keeps a certain amount of water outlet in the air inlet process. On the contrary, when the second liquid outlet 93 is closer to the air dissolving device 1, 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 cavity 16 can be discharged from the liquid outlet pipe 6, the second pipeline 9, the liquid inlet pipe 7, the first pipeline 8 and the liquid outlet pipe 6 in sequence, so that the pressure in the mixing cavity 16 is reduced, and the air inlet pipe 5 is used for introducing air into the mixing cavity 16. The direction of the pump liquid in the pump body 75 can be changed according to the actual design, thereby changing the circulating discharge direction of the liquid.

As shown in fig. 3 and 4, when the feed liquor pipe 7 communicates the 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 be fast dissolved in liquid, realize the dissolved gas of mixing chamber 16, and then drain pipe 6 can outwards discharge the 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.

The utility model discloses micro-nano bubble liquid generation system 100, pump body 75 can realize opening or closing under the flow path of difference. For example, when the air inlet pipe 5 in fig. 2 is used for introducing air into the mixing chamber 16, the pump body 75 is opened to provide certain power for draining the mixing chamber 16, so that the liquid in the mixing chamber 16 enters the first pipeline 8 from the first liquid outlet end 83 which is closer to the air dissolving device 1 preferentially; the liquid is introduced into the second pipeline 9 under the action of the pump body 75, and the liquid in the second pipeline 9 reenters the position of the liquid outlet pipe 6, which is closer to the water use terminal, from the second liquid outlet end 93, so that the liquid is output to the water use terminal through the liquid outlet pipe 6; or enters the second pipeline 9 from the second liquid outlet end 93 which is closer to the air dissolving device 1, and is introduced into the first pipeline 8 through the action of the pump body 75, and the liquid in the first pipeline 8 reenters the position of the liquid outlet pipe 6 which is closer to the water using terminal from the first liquid outlet end 83, so as to be output to the water using terminal through the liquid outlet pipe 6.

For example, when the liquid inlet pipe 7 is used for feeding liquid into the mixing chamber 16 in the aforementioned fig. 3, the pump body 75 is closed to feed liquid into 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 utility model has simple structure and low cost; the whole body is modularized, the size is small, the arrangement is compact, the device is conveniently used for small equipment, the occupied size can be changed, different use scenes are met, the noise is low, and the vibration is small. Compare the scheme that needs rely on the air pump to carry out air admission control among the prior art, the utility model discloses a pressure differential between the mixing chamber 16 and the intake pipe 5 realizes admitting air when the 75 flowing back of the pump body of micro-nano bubble liquid generation system 100 accessible pump body, and the part has been simplified to the controllable pressure boost feed liquor, has improved the dissolved gas efficiency of admitting air of mixing chamber 16. Compare in prior art between the micro-nano bubble goes out water and the ordinary system that goes out correlation between the water between difficult, the inconvenient scheme, the utility model discloses a micro-nano bubble liquid generation system 100 accessible adjusts the switching of the different valve bodies of switching and the operation of pump body 75 and realizes the quick switch-over between micro-nano bubble goes out water and the ordinary water, and water terminal water use form is nimble.

In the description of the present invention, features defined as "first", "second", "third" and "fourth" may explicitly or implicitly include one or more of the features for distinguishing between descriptive features, non-sequential, non-trivial and non-trivial.

It should be noted that, the liquid in the present invention refers to the liquid dissolved with certain gas, or the heated liquid, or the lower tap water of temperature with certain impurity, or the purified water purified by the purification device, or the comparatively pure water supplied in the living water tank, and the water intake described in the present invention mainly refers to the liquid intake, and the water outtake mainly refers to the liquid outtake, and the extensive understanding should be done, and should not be narrowly limited to the water described in the chemical field.

Optionally, the utility model provides a first valve body, second valve body, third valve body, fourth valve body all can choose for use normally open valve or normally closed valve, also can be for simple solenoid valve, as long as can control corresponding pipeline break-make then can.

In some embodiments of the present invention, as shown in fig. 1, fig. 7 and fig. 8, the micro-nano bubble liquid generating system 100 further includes a first check valve 62, the first check 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 check valve 62 makes the liquid outlet pipe 6 conduct in one direction.

Taking the example where the first water end 83 is closer to the air dissolving device 1 than the second water end 93, then in these examples, the first one-way valve 62 can make the liquid in the liquid outlet pipe 6 only flow from the direction of the air dissolving device 1 to the direction of the second liquid outlet end 93, but not in the opposite direction; alternatively, the first one-way valve 62 can make the liquid in the outlet pipe 6 flow only from the first outlet end 83 to 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, during the operation of the pump body 75, the liquid in the air dissolving device 1 can only be sucked into the first pipeline 8 and discharged from the second pipeline 9 to the liquid outlet pipe 6, and the liquid discharged to the liquid outlet pipe 6 cannot reversely flow to the first liquid outlet end 83 through the first check valve 62, so that when the pump body 75 operates, the liquid in the mixing cavity 16 can be continuously discharged from the liquid outlet pipe 6 to the water use terminal, and the water flow is prevented from forming a dead cycle.

Of course, in other examples, the first check valve 62 may not be provided, and the distance between the second liquid outlet 93 and the first liquid outlet 83 may be increased, so that the second liquid outlet 93 is further arranged relative to the first liquid outlet 83, and no matter how the pump 75 operates, the liquid in the second pipeline 9 is not pumped back into the first pipeline 8, and no dead circulation of the water flow is formed when the mixing chamber 16 is used for discharging liquid and air.

In some embodiments of the present invention, the mode of the mixing chamber 16 has an air intake mode and an air dissolving mode, and the switching of the modes is realized 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 respectively communicate with the liquid inlet pipe 7 and the liquid outlet pipe 6, meanwhile, 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 using terminal does not stop flowing before the mixing cavity 16 discharges liquid, and the water using terminal can keep water inlet 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, under the dissolved air mode, the utility model discloses a pump body 75 is opened, and pump body 75 can further increase the flow of the device 1 feed liquor of dissolving air or the pressure of feed liquor, and then promotes the effect of dissolving air. 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 a 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 gas liquid exists in the gas dissolving device 1, either the dissolved gas liquid can be discharged outwards or the normal liquid can be directly discharged outwards, so that the output of the dissolved gas liquid and the output of the normal bubble-free liquid can be switched efficiently and conveniently, and flexible water use is realized by using the water terminal.

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 terminal can obtain a large amount of water without bubbles without discharging liquid through the air dissolving device 1, so that a 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 comprises a second one-way valve 51, and the second one-way valve 51 is disposed on the air inlet pipe 5, so that the air flows from the air inlet pipe 5 to the mixing chamber 16 in one direction. 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 increased, and the gas dissolving effect is ensured.

The second check valve 51 can effectively control the flow direction of the airflow in the air inlet pipe 5, so that the airflow can only be inflated towards the mixing chamber 16 from the inflator 52 in a single direction, and the opposite process is not performed, thereby ensuring that the pressure between the air inlet pipe 5 and the air dissolving device 1 is controllable, and preventing the air dissolving device 1 from being decompressed and even incapable of being inflated. 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 combination of the inflator 52 and the pump body 75 of the present invention provides for more efficient intake of air into 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 1/5 to 1, 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 1/5, 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 bubbles in the mixing cavity 16 are mixed, the amount of water to be dissolved in the dissolved water cavity is small, and the air bubbles are mixed, so that the water cannot be completely dissolved into water, thereby causing resource waste and affecting the requirement of a user for using the dissolved water.

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 1/5 to 1, 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, and 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 can be more dense and the content of micro-nano bubbles is more, so that 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.

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 smaller than 1/4, the volume of the mixing cavity 16 is smaller, 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 dissolving water cavity is greater than 1, the volume of the mixing cavity 16 is large, the air bubbles in the mixing cavity 16 are mixed more, the liquid to be dissolved in the dissolving 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, etc.

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

In some embodiments, the ratio of the vertical dimension of the partition 15 to the vertical 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 part of baffle 15 and casing 14 interval 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 size 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 15 in the vertical direction to the dimension of the cross section of the position where the partition 15 is located is larger than 0.9, the distance between the upper side of the partition 15 and the upper end of the shell 14 is large, 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 15, so that the air bubble mixed flow in the main cavity is incompletely and unevenly 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 water in the main cavity is accelerated, and the air bubble mixed flow and 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.
