The inlet flow path 7 may introduce liquid into the mixing chamber 16 and the inlet gas path 5 may introduce gas into the mixing chamber 16.
Further, the air inlet assembly 50 is connected with the air dissolving device 1, the air inlet assembly 50 enables the air inlet path 5 to inlet air to the mixing cavity 16, and at the moment, the air in the mixing cavity 16 is increased continuously; and the gas and the liquid in the gas dissolving device 1 are mixed to form a gas-liquid mixed liquid.
The air intake assembly 50 includes a check valve 51, and the check valve 51 is provided on the air intake path 5 to control an air intake direction of the air intake path 5.
According to the structure, in the micro-nano bubble liquid generation system 100 provided by the embodiment of the invention, the air inlet assembly 50 can quickly inlet air towards the air dissolving device 1, so that the air dissolving device 1 is filled with air; dissolve gas device 1 outwards discharges liquid simultaneously at the process of admitting air to the gas-liquid mixture in the in-process that admits air dissolves gas device 1 can flow out to the water end, and whole process need not to cut off water, provides the guarantee for follow-up formation micro-nano bubble water. The one-way valve 51 is provided to allow the gas in the gas inlet path 5 to move toward the mixing chamber 16 during the gas inlet and liquid outlet processes, so that the gas inlet and liquid outlet operations of the mixing chamber 16 are reliable.
Compared with the pressurizing and air dissolving method which needs a booster pump for pressurization in the prior art, the invention has the advantages of simple structure and low cost; the whole body is modularized, the size is small, the arrangement is compact, the device is convenient to be used on small equipment, and the occupied size can be changed to meet different use scenes; the cost performance of the product is improved, the air inlet and air dissolving process is simple to control, water can not be cut off at the water end, the air can be filled midway, the condition of water flow closing does not exist, the user experience is good, and the starting speed of the whole machine is improved.
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 lower temperature, or a purified water purified by a purification device, or a relatively pure water supplied to a living water tank, and the water inlet described in the present invention refers to a liquid inlet mainly, and the water outlet refers to a liquid outlet mainly, which should be understood widely, and should not be limited to the water described in the chemical field.
In some embodiments of the present invention, the liquid passage pressure regulating valve assembly 70 in the above example is provided on the intake liquid flow passage 7, the liquid passage pressure regulating valve assembly 70 is used to regulate the pressure of the intake liquid flow passage 7, and the liquid passage pressure regulating valve assembly 70 has a large water pressure state and a small water pressure state, that is, the liquid passage pressure regulating valve assembly 70 can regulate the gas pressure and the water pressure in the gas dissolving apparatus 1, thereby changing the internal state of the mixing chamber 16.
Correspondingly, when the liquid path pressure regulating valve assembly 70 is in a low water pressure state, the air dissolving device 1 is in an air inlet state and the air inlet assembly 50 is operated, so that the air inlet path 5 is enabled to inlet air to the mixing cavity 16; when the liquid path pressure regulating valve assembly 70 is in a high water pressure state, the gas dissolving device 1 is in a gas dissolving state and the gas in the mixing chamber 16 is dissolved with the liquid phase to form a gas dissolving liquid.
The air inlet assembly 50 cooperates with the liquid path pressure regulating valve assembly 70 to regulate the pressure of the liquid inlet flow path 7, so as to keep the pressure of the liquid inlet end of the air dissolving device 1 at a preset value, and change the flow rate of the liquid in the liquid inlet flow path 7 and the air pressure in the mixing cavity 16.
Then, when the liquid path pressure regulating valve assembly 70 is switched to a low water pressure state, a small amount of liquid is formed in the liquid inlet flow path 7 at this time, the amount of liquid flowing out of the mixing cavity 16 is larger than the amount of liquid flowing in, the air pressure in the mixing cavity 16 is reduced, and after the air pressure in the mixing cavity 16 is smaller than the air pressure in the air inlet path 5, the gas in the gas source communicated with the air inlet path 5 can be charged into the mixing cavity 16, so that the gas can be rapidly charged toward the gas dissolving device 1 on the premise that the water pressure of the liquid inlet flow path 7 is stable, so that the required gas is charged into the gas dissolving device 1, and the gas charging process of the gas dissolving device 1 is realized. Meanwhile, as a certain amount of liquid is always stored in the air dissolving device 1 and the air dissolving device 1 keeps feeding liquid, the liquid can be discharged from the liquid outlet flow path 6 to the water using end all the time in the air feeding process of the air dissolving device 1, and the water cut is prevented.
After the gas dissolving device 1 is filled with more gas, the liquid path pressure regulating valve assembly 70 is switched to a high water pressure state, at the moment, the liquid inlet flow path 7 forms large flow liquid inlet, the amount of the liquid flowing into the mixing cavity 16 is larger than the amount of the liquid flowing out, so that more liquid flows into the mixing cavity 16 rapidly to stably increase the pressure in the mixing cavity 16, the gas filled into the gas dissolving device 1 is further promoted to be dissolved into the liquid rapidly to form gas dissolving liquid, and reliable guarantee is provided for the subsequent further generation of micro-nano bubble water.
It can be seen that, in the present invention, the air inlet assembly 50 and the liquid path pressure regulating valve assembly 70 are matched with each other, so that the air dissolving device 1 can be greatly facilitated to perform air inlet and air dissolving, and water can be always supplied to a user.
In some embodiments of the present invention, as shown in the sixth aspect example of fig. 19, 20, 21, the seventh aspect example of fig. 22, 23, and 24, the eighth aspect example of fig. 26, 27, and 28, and the ninth aspect example of fig. 29-31, the intake assembly 50 includes a pump body 53, and the pump body 53 draws liquid to cause the intake air path 5 to intake air toward the mixing chamber 16 in a low water pressure state. In these examples, since the liquid amount flowing into the mixing chamber 16 from the liquid inlet flow path 7 is small under a small water pressure, the pump body 53 can rapidly pump out the liquid at the corresponding position, so as to form a low-pressure region with a pressure lower than the pressure of the air source outside the air inlet path 5, so as to promote the air source to enter the low-pressure region, and finally, the air dissolving device 1 is filled with more air.
It should be noted that the pump body 53 may be a common water pump for pumping water.
For example, as shown in fig. 19, 20, and 21, which are examples of a sixth aspect, and fig. 26, 27, and 28, which are examples of an eighth aspect, the gas dissolving device 1 is formed with a liquid outlet flow path 6 communicating with the mixing chamber 16, and the pump body 53 is provided on the liquid outlet flow path 6 for pumping the liquid in the gas dissolving device 1 so that the gas pressure in the gas dissolving device 1 is lower than the gas pressure in the gas inlet path 5, and the gas inlet path 5 introduces gas into the mixing chamber 16. In these examples, when the pressure regulating valve assembly 70 is in a low pressure state, the liquid flow rate entering the liquid inlet flow path 7 to the mixing chamber 16 is small, and during the pumping process of the pump body 53, the liquid in the mixing chamber 16 will decrease sharply, so that the air pressure in the mixing chamber 16 with a certain volume is reduced, and a certain low pressure area is formed in the mixing chamber 16; meanwhile, the air pressure in the mixing chamber 16 is also rapidly reduced to be lower than the air pressure of the air source supply system connected with the air inlet path 5, at this time, the air can rapidly inflate into the mixing chamber 16 through the air inlet path 5, so that the mixing chamber 16 completes efficient air inlet, and the pressure in the mixing chamber 16 is relatively stable.
On the contrary, when the pump body 53 stops pumping, the liquid path pressure regulating valve assembly 70 is in a state of high water pressure and rapidly discharges liquid toward the mixing chamber 16, so that the gas space in the liquid inlet flow path 7 is sharply reduced, the pressure in the gas dissolving device 1 is increased, and the gas previously entering the mixing chamber 16 can be more rapidly dissolved into the liquid to form gas-dissolved liquid.
For another example, as shown in the seventh example of fig. 22, 23, and 24 and the ninth example of fig. 29 to 31, the air dissolving device 1 is further provided with a merging channel 8 communicating with the mixing chamber 16, one end of the merging channel 8 communicates with the intake channel 7 and the intake air channel 5, respectively, and the other end of the merging channel 8 communicates with the mixing chamber 16. Both the gas and the liquid can now enter the mixing chamber 16 through the converging flow path 8.
Further, the pump body 53 is provided on the merging flow path 8, and in a low water pressure state, the pump body 53 pumps the liquid to make the intake air path 5 intake the mixing chamber 16, and specifically, the pump body 53 pumps the liquid at the rear of the liquid path pressure regulating valve assembly 70, so that the liquids in the intake flow path 7 to the mixing chamber 16 are rapidly reduced and form a certain low pressure region, and the liquid pumped by the pump body 53 is discharged into the mixing chamber 16, and the low pressure region is simultaneously connected with the intake air path 5, so that the low pressure region will rapidly make the gas in the gas source supply system connected with the intake air path 5 enter the mixing chamber 16 through the merging flow path 8, thereby filling the mixing chamber 16 with the required gas amount.
On the contrary, the liquid amount of the liquid inlet flow path 7 is large under the large water pressure state, so that the liquid quickly enters the mixing chamber 16 through the converging flow path 8, the pump body 53 stops running, the space rich in air in the mixing chamber 16 is quickly filled with the liquid, the pressure of the gas dissolving device 1 is further increased, and the gas dissolving device 1 enters the gas dissolving state, so that the gas entering the mixing chamber 16 can be dissolved in the liquid and form a sufficient amount of gas dissolving liquid for subsequent use.
In some embodiments of the present invention, as shown in the first aspect example in fig. 1-2, the second aspect example in fig. 4-5, the third aspect example in fig. 7-8, the fourth aspect example in fig. 12-13, and the fifth aspect example in fig. 16-17, the intake assembly 50 includes an inflator 52, the inflator 52 is disposed on the intake air path 5, 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.
In some examples, the inflator 52 alone may be used to achieve air intake control and efficient air intake of the mixing chamber 16, such as the first aspect example in fig. 1-2, the second aspect example in fig. 4-5, the third aspect example in fig. 7-8, the fourth aspect example in fig. 12-13, and the fifth aspect example in fig. 16-17.
In other examples, the inflator 52 may also be used in the foregoing examples with the pump body 53, such as in the examples of the sixth aspect in fig. 19, 20, 21, the examples of the seventh aspect in fig. 22, 23, and 24, the examples of the eighth aspect in fig. 26, 27, and 28, and the examples of the ninth aspect in fig. 29-31, so as to implement the combination of the inflator 52 and the pump body 53.
In a specific example, the pump body 53 can pump liquid to reduce the pressure in the mixing chamber 16 or reduce the pressure in the liquid inlet flow path 7, and then the inflator 52 is actively operated to raise the pressure in the air inlet path 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 chamber 16 is controlled more quickly, and the efficient air inlet of the mixing chamber 16 is easier to realize. The above examples are intended to fall within the scope of the present invention.
Alternatively, in examples where the aforementioned aspects are provided with an inflator 52, the check valve 51 inflates the inflator 52 towards the mixing chamber 16. The one-way valve 51 can effectively control the flowing direction of the air flow in the air inlet path 5, so that the air flow can only be inflated from the inflator 52 to the mixing chamber 16 in one direction, but not in the opposite process, thereby ensuring that the pressure between the air inlet path 5 and the air dissolving device 1 is controllable, and preventing the air dissolving device 1 from releasing pressure or even being incapable of air inlet.
Of course, in various examples without the inflator 52, the check valve 51 may be disposed on the air intake path 5, so that the air of the air source connected to the air intake path 5 can flow into the air dissolving device 1 in one direction, and does not flow back to the air source from the air dissolving device 1 in the opposite direction, thereby ensuring that the pressure of the air dissolving device 1 after air intake is controllable.
As shown in the fifth aspect example in fig. 16-17, the sixth aspect example in fig. 20 and 21, the seventh aspect example in fig. 22, 23 and 24, the eighth aspect example in fig. 27 and 28, and the ninth aspect example in fig. 29-31, the micro-nano bubble liquid generating system 100 further includes a pressure stabilizing valve 72, the pressure stabilizing valve 72 is arranged in parallel with the liquid path pressure regulating valve assembly 70, and the pressure stabilizing valve 72 can ensure the pressure at the liquid inlet end of the air dissolving device 1, so that the air dissolving device 1 can be fed with liquid under a certain pressure; smooth air intake of the air intake path 5 can also be achieved by selecting the pressure maintaining valves 72 having different pressures. In a specific example, if the water outlet pressure of the pressure stabilizing valve 72 is P1, the air outlet pressure of the inflator 52 is P2, and the pressure P2 is controlled to be equal to or greater than P1, smooth liquid inlet of the liquid inlet flow path 7 can be realized, and smooth air inlet of the air inlet air path 5 is ensured.
Alternatively, as shown in each example of fig. 16, 17, 20, 22, 27 and 29, both ends of the regulator valve 72 may be provided in the intake passage 7 in parallel with the pressure regulating valve unit 70. In these examples, the pressure stabilizing valve 72 and the water inlet end of the liquid path pressure regulating valve assembly 70 intersect and are connected with a water source through a pipeline, and the pressure stabilizing valve 72 and the water outlet end of the liquid path pressure regulating valve assembly 70 intersect and then converge into the air dissolving device 1, so that after the water pressure is regulated by the pressure stabilizing valve 72, the pressure and the water flow of one end of the liquid inlet connected with the air dissolving device 1 are regulated and controlled, and a certain amount of liquid is ensured to be contained in the air dissolving device 1, and the water using end is not cut off.
In these examples, the liquid path pressure regulating valve assembly 70 may select its own flow regulating valve 78 capable of regulating the flow, and when the pressure stabilizing valve 72 operates, the liquid outlet flow of the liquid inlet flow path 7 is the sum of the liquid outlet flow of the flow regulating valve 78 and the liquid outlet flow of the pressure stabilizing valve 72; when the pressure stabilizing valve 72 is closed, the liquid outlet flow of the liquid inlet flow path 7 is the liquid outlet flow of the flow regulating valve 78. The liquid path pressure regulating valve assembly 70 can also select a normally open valve which can be opened and closed, and when the pressure stabilizing valve 72 operates and the normally open valve is closed, the liquid outlet flow of the liquid inlet flow path 7 is the liquid outlet flow of the pressure stabilizing valve 72; when the pressure stabilizing valve 72 is closed and the normally open valve is opened, the liquid outlet flow of the liquid inlet flow path 7 is the liquid outlet flow of the normally open valve, so that different liquid outlet flow regulation under different liquid inlet pressures is realized.
Alternatively, in the examples shown in fig. 23 and 30, one end of the liquid separation flow path 81 connected to the pressure stabilizing valve 72 is connected to the liquid inlet end of the liquid path pressure regulating valve assembly 70, and the other end is connected to the liquid inlet end of the air dissolving device 1, in these examples, the hydraulic pressure of the liquid inlet flow path 7 can be adjusted, so that the liquid outlet flow rate in the liquid inlet flow path 7 can be adjusted, and a certain amount of water can be kept in the air dissolving device 1 without water cut-off. The liquid passage pressure regulating valve assembly 70 in these examples may be a flow regulating valve 78 or a normally open valve that can regulate the flow rate thereof, and the liquid separation flow passage 81 may be connected to the rear end of the pump body 53 in order to reduce the pumping pressure of the pump body 53, so that the pump body 53 only pumps the liquid in the liquid inlet flow passage 7 and does not need to pump the liquid in the liquid separation flow passage 81. For the liquid flow rate finally entering the air dissolving device 1, see the determination manner of the liquid outlet flow rate of the liquid inlet flow path 7 in the example in which the two ends of the pressure stabilizing valve 72 are connected in parallel with the liquid path pressure regulating valve assembly 70 and then are arranged on the liquid inlet flow path 7 in the previous example.
Or, in the examples shown in fig. 21, 24, 28 and 31, one end of the liquid separation flow path 81 connected to the pressure stabilizing valve 72 is connected to the liquid inlet end of the liquid path pressure regulating valve assembly 70, and the other end is connected to the liquid outlet flow path 6 of the mixing chamber 16, in these examples, after the pressure stabilizing valve 72 is opened, part of the liquid can also enter the liquid outlet flow path 6 through the liquid separation flow path 81, the pressure stabilizing valve 72 can further mix the dissolved gas liquid in the mixing chamber 16 with the water in the liquid separation flow path 81 while adjusting the water pressure in the liquid inlet flow path 7, so as to flow out toward the micro-nano water end together, so that the pressure of the whole bubble liquid generating system 100 is stabilized, and the liquid outlet flow path 6 can keep a certain amount of water outlet, thereby preventing the system from water cut-off. The liquid path pressure regulating valve assembly 70 in these examples can select the flow regulating valve 78 or the normally open valve which can regulate the flow, at this time, the liquid outlet flow of the pressure stabilizing valve 72 does not influence the liquid inlet flow of the air dissolving device 1, the liquid inlet flow of the air dissolving device 1 is equal to the liquid outlet flow of the flow regulating valve 78 or equal to the liquid outlet flow of the normally open valve, and the liquid separating flow path 81 is connected to the liquid outlet flow path 6, so when the pressure stabilizing valve 72 is opened, part of the liquid passing through the pressure stabilizing valve 72 can further flow into the water using end, and the water cut-off is prevented. The surge tank valve 72 in these examples is mainly a surge tank valve 72 that is generally used to realize open/close pressure regulation.
Therefore, in the present invention, when the pressure maintaining valve 72 is provided, the position of the pressure maintaining valve 72 can be appropriately adjusted according to actual needs.
Advantageously, a liquid inlet one-way valve can be arranged on the liquid separation flow path 81, so that the liquid flows from the pressure stabilizing valve 72 to the liquid outlet end without the opposite direction, and the pressure stability of the system is ensured.
Optionally, the pressure regulating valve assembly 70 for the liquid path adopts a flow regulating valve 78, the flow regulating valve 78 may be a flow valve with a continuously adjustable opening, the structure of the flow valve with a continuously adjustable opening may change the flow in the path by the rotation of a valve plate, and the specific rotation implementation form of the valve plate is not described herein; the flow switching valve can also realize variable output of multi-gear liquid outlet flow.
The flow switching valve with variable output of multi-gear output liquid flow is mainly described as outputting two-gear output liquid flow.
As shown in fig. 33 and 34, the flow switching valve includes a valve housing 781 having a valve inlet 7811 and a valve outlet 7812 that are communicable, a flow stabilizing assembly 782, and a driving assembly 783. The flow stabilizing assembly 782 and the driving assembly 783 are arranged in the valve casing 781 and divide the valve casing 781 into a first cavity and a second cavity, the first cavity is communicated with the valve inlet 7811, the second cavity is communicated with the valve outlet 7812, a first water passing channel communicated with the first cavity and the second cavity is formed in the middle of the flow stabilizing assembly 782, and a second water passing channel communicated with the first cavity and the second cavity is formed at one end of the flow stabilizing assembly 782; the driving assembly 783 can control the on-off of the first water passing channel or the second water passing channel, so that the water yield of the valve outlet 7812 can be adjusted.
Alternatively, as shown in fig. 33 and 34, the flow stabilization assembly 782 includes a flow stabilization valve spool 7821 and a flow stabilization valve body 7822, the flow stabilization valve body 7822 being disposed within the valve housing 781, the flow stabilization valve body 7822 having opposite ends directed toward the valve inlet 7811 and valve outlet 7812, respectively; the flow stabilizing valve core 7821 is arranged in the flow stabilizing valve body 7822, and a first water passing channel is formed in the flow stabilizing valve core 7821; a second water passing channel is formed at the edge of the steady flow valve body 7821 close to the driving assembly 783, and when the output end of the driving assembly 783 moves towards the position close to the second water passing channel, the second water passing channel is closed, so that the liquid entering from the valve inlet 7811 can only flow out from the first water passing channel to the valve outlet 7812, and at the moment, the flow switching valve is in a low water pressure state and outputs a low flow, which is beneficial to the air dissolving device 1 to realize air inlet; when the output end of the driving component 783 moves towards the direction far away from the second water passing channel, the second water passing channel is opened, so that liquid entering from the valve inlet 7811 can flow out from the first water passing channel to the valve outlet 7812, and liquid entering from the valve inlet 7811 can flow out from the second water passing channel to the valve outlet 7812, at the moment, the flow switching valve is in a large water pressure state, and the output of the flow switching valve is large in flow, and the gas dissolving device 1 is facilitated to realize gas dissolving.
Alternatively, as shown in fig. 33 and 34, the driving assembly 783 comprises a driving member 7831 and a blocking member 7832, the blocking member 7832 is connected to the output end of the driving member 7831, and the blocking member 7832 can move relative to the second water passage to open or close the second water passage. The outer contour of the barrier 7832 is preferably configured and dimensioned to completely block the second water passage, such that the second water passage is completely blocked when the barrier 7832 is closed over the second water passage.
Alternatively, the driving member 7831 can be selected from a cylinder, a stepping motor or an electric push rod, as long as the stepping movement of the blocking member 7832 can be achieved, and is not particularly limited herein.
Alternatively, the blocking member 7832 may be made of a partition, a diaphragm, a sealing plug, etc., as long as it can block the second water passage, and is not limited herein.
It is to be noted that the flow rate adjustment valve 78 in the present invention may also be used in the example shown in fig. 19, fig. 26, in which the pressure maintaining valve 72 is not provided, and is not limited to the example that occurs simultaneously with the pressure maintaining valve 72. In each example in which only the flow rate adjustment valve 78 is provided, the inlet flow rate in the air dissolving device 1 depends on the magnitude of the outlet flow rate of the flow rate adjustment valve 78.
The following describes in detail an integrated adjustable flow valve with integrated pressure maintenance valve 72 and flow control valve 78.
As shown in fig. 35, when the pressure-maintaining valve 72 and the flow-regulating valve 78 are integrally provided on the inlet flow path 7, the integrated variable flow valve has a valve inlet end and a valve outlet end, and the liquid entering from the valve inlet end can flow to the valve outlet end through the pressure-maintaining valve 72 being opened, or the liquid entering from the valve inlet end can flow to the valve outlet end through the flow-regulating valve 78. Because the flow regulating valve 78 can always maintain a certain flow capacity, the valve outlet end of the integrated adjustable flow valve always has a certain outlet flow.
The flow rate control valve 78 is selected from the flow rate switching valves described above, and the flow rate of the flow rate switching valve in a low water pressure state is assumed to be L Small The flow rate of the flow rate switching valve in a high water pressure state is L Big (a) The outlet pressure of the flow switching valve is P Valve with a valve body The liquid outlet flow of the flow switching valve is L Valve with a valve body (ii) a Pressure regulator valve 72 has a pressure P Voltage stabilization The liquid outlet flow of the pressure stabilizing valve 72 is L Voltage stabilization (ii) a The liquid outlet pressure of the integrated adjustable flow valve is P Go out The liquid outlet flow of the integrated adjustable flow valve is L Go out 。
When the integrated adjustable flow valve is in a steady flow and steady pressure state or a low flow state, the driving component 783 closes the second water passing channel of the flow switching valve, so that liquid can only flow out through the first water passing channel but not from the second water passing channel, and L can be obtained at the moment Valve with a valve body ＝L Small (ii) a When P is designed Voltage stabilization ≥P Valve with a valve body Then the surge valve 72 opens and final P Go out ＝P Voltage stabilization ，L Go out ＝L Small +L Voltage stabilization (ii) a When P is designed Voltage stabilization <P Valve with a valve body Then surge valve 72 is closed and final P Go out ＝P Valve with a valve body ，L Go out ＝L Small 。
When the integrated adjustable flow valve is in a large-flow state, the driving component 783 opens the second water passing channel of the flow switching valve, so that liquid can flow out through the first water passing channel and the second water passing channel, and L can be obtained at the moment Valve with a valve body ＝L Small +L Big (a) (ii) a When P is designed Voltage stabilization ≥P Valve with a valve body Then the surge valve 72 opens and final P Go out ＝P Voltage stabilization ，L Go out ＝L Small +L Big (a) +L Voltage stabilization (ii) a When P is designed Voltage stabilization <P Valve with a valve body Then surge valve 72 is closed and final P Go out ＝P Valve with a valve body ，L Go out ＝L Small +L Big (a) 。
Therefore, the pressure stabilizing valve 72 not only can stabilize the liquid outlet pressure of the integrated adjustable flow valve when being opened, but also can adjust the liquid outlet flow of the integrated adjustable flow valve. When the pressure stabilizing valve 72 is closed, the liquid outlet pressure of the integrated adjustable flow valve is adjusted through the liquid outlet pressure of the flow switching valve, and the liquid outlet flow of the integrated adjustable flow valve can form different large-flow water outlets, so that the liquid inlet in the gas dissolving device 1 can be always kept and the gas dissolving device cannot be completely closed.
It should be noted that the integrated adjustable flow valve of the present invention is mainly applied to the case where both ends of a regulator valve 72 shown in each example of fig. 16, 17, 20, 22, 27, and 29 are connected in parallel with a liquid path pressure regulating valve assembly 70 and then provided on the liquid inlet flow path 7.
When the integrated adjustable flow valve is not used, two pipelines can be used for enabling the pressure stabilizing valve 72 and the flow regulating valve 78 to be connected in parallel and arranged in a split mode.

That is, the first tee 791 is connected to the pressure maintaining valve 72 and the flow regulating valve 78, and two flow paths in the first tee 791 are respectively communicated with the pressure maintaining valve 72 and the flow regulating valve 78, so that the liquid is respectively shunted to the pressure maintaining valve 72 or the flow regulating valve 78 through the first tee 791.
Similarly, the second tee 792 is also connected with the pressure stabilizing valve 72 and the flow regulating valve 78 respectively, and two flow paths of the second tee 792 are communicated with the pressure stabilizing valve 72 and the flow regulating valve 78 respectively, so that liquid in the pressure stabilizing valve 72 can flow out through the second tee 792, or liquid in the flow regulating valve 78 can flow out through the second tee 792, and finally the whole integrated adjustable flow valve is compact in structure, small and exquisite and convenient to install, the liquid outlet pressure regulating effect is good, the liquid outlet flow is adjustable, the air dissolving device 1 is convenient to realize quick air dissolving after air inlet, and water end water supply can be guaranteed.
In the description of the present invention, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features for distinguishing between the described features, whether they are sequential or not.
In a specific example, the first three-way 791 is in threaded or snap connection with the water inlet side of the pressure maintaining valve 72 and the water inlet side of the flow regulating valve 78, so that the first three-way 791 is connected with the pressure maintaining valve 72.
In other examples, the integral connection of the first tee 791 and the pressure maintaining valve 72 may also be made by welding, and the integral connection of the first tee 791 and the flow regulating valve 78 may also be made by welding. Similarly, the second tee 792 is connected with the pressure maintaining valve 72 by screw or snap connection with the water outlet side of the pressure maintaining valve 72 and the water outlet side of the flow regulating valve 78. In other examples, the integral connection of the second tee 792 and the regulator valve 72 may also be achieved by welding, and the integral connection of the second tee 792 and the flow control valve 78 may also be achieved by welding.
Optionally, the two water outlet ends of the first tee 791 and the two water inlet ends of the second tee 792 correspond to and are coaxially disposed with each other, thereby reducing resistance to over-flow. In cooperation with the pressure stabilizing valve 72, the water inlet side and the water outlet side of the pressure stabilizing valve are coaxially arranged with the water outlet end of the corresponding first tee 791 and the water inlet end of the corresponding second tee 792, so that the pressure stabilizing valve is convenient to connect and has small water passing resistance; the water inlet side and the water outlet side of the flow regulating valve 78 are also coaxially arranged with the water outlet end of the corresponding first tee 791 and the water inlet end of the corresponding second tee 792, so that the connection is convenient and the water passing resistance is small.
As shown in FIGS. 36 and 37, in order to provide the flow control valve 78 in the integrated variable flow valve, the flow control valve 78 should be matched in size to the outlet end of the first tee 791 and the inlet end of the second tee 792, and corresponding screw or groove fittings are provided on the inner walls of the flow control valve 78 on the inlet side and the outlet side.
Alternatively, as shown in fig. 38 and 39, a schematic view of a surge damping valve 72 provided in an integrated adjustable flow valve is shown. The pressure stabilizing valve 72 comprises a pressure stabilizing shell 721 and an adjusting component 724 arranged in the pressure stabilizing shell 721, a pressure stabilizing inlet 722 and a pressure stabilizing outlet 723 which are communicated are arranged in the pressure stabilizing shell 721, a pressure stabilizing runner communicated with the pressure stabilizing inlet 722 and the pressure stabilizing outlet 723 is arranged in the pressure stabilizing shell 721, and the adjusting component 724 can conduct or cut off the pressure stabilizing runner when moving, so that the pressure stabilizing valve 72 is in an open state when the adjusting component 724 conducts the pressure stabilizing runner; when the regulating member 724 blocks the pressure-stabilizing flow passage, the pressure-stabilizing valve 72 is in a closed state.
Advantageously, the adjusting assembly 724 may include a solenoid rod assembly and an electromagnetic mating piece, which form a magnetic attraction when the solenoid rod assembly and the electromagnetic mating piece are energized to cut off the voltage stabilizing flow passage; when the electromagnetic valve component and the electromagnetic matching piece are powered off, the voltage stabilizing flow passage is conducted.
In order to keep the electromagnetic valve rod assembly at a specific position, an elastic reset piece is arranged between the electromagnetic valve rod assembly and the electromagnetic matching piece, so that after the electromagnetic valve rod assembly and the electromagnetic matching piece are powered off, the reset force of the elastic reset piece drives the electromagnetic valve rod assembly to move towards one side far away from the electromagnetic matching piece to open the pressure stabilizing flow channel.
Of course, the adjusting assembly 724 is not limited to the solenoid rod assembly and the electromagnetic mating member, and for example, in other examples, the adjusting assembly may be in the form of an electric push rod or an air cylinder driven sealing plug, which is not limited herein.
Alternatively, the telescopic movement direction of the adjusting assembly 724 is perpendicular to a connecting line formed by the pressure stabilizing inlet 722 and the pressure stabilizing outlet 723, so that the pressure stabilizing flow passage can be reliably intercepted when the adjusting assembly 724 changes posture.
Various examples of intake assembly 50 using only inflator 52 are described below.
As shown in the first aspect example in fig. 1 to 2, the second aspect example in fig. 4 to 5, the third aspect example in fig. 7 to 8, the fourth aspect example in fig. 12 to 13, and the fifth aspect example in fig. 16 to 17, the inlet flow path 7 communicates with the mixing chamber 16 through the inlet 12, the inlet gas path 5 communicates with the mixing chamber 16 through the inlet 11, the mixing chamber 16 is further provided with the outlet 13, and the outlet 13 communicates with the outlet flow path 6.
That is, the gas dissolving device 1 has a liquid inlet 12, a gas inlet 11 and a liquid outlet 13 through its container wall, wherein the mixing chamber 16 is communicated with an external flow path or gas path through the liquid inlet 12, the gas inlet 11 and the liquid outlet 13.
Further, as shown in the first aspect example in fig. 1-2 and the second aspect example in fig. 4-5, the liquid path pressure regulating valve assembly 70 includes a water inlet valve 74 and a pressure maintaining valve 72, the liquid inlet flow path 7 is provided with a water inlet valve 74 for controlling the on-off of the water flow in the liquid inlet flow path 7 and a pressure maintaining valve 72 for stabilizing the water inlet pressure of the liquid inlet 12, and the air pressure pumped by the inflator 52 is not less than the water inlet pressure of the liquid inlet 12. That is, in these examples, the pressure maintaining valve 72 is provided before the inlet 12 simultaneously with the inlet valve 74. The pressure stabilizing valve 72 is used for stabilizing water inlet pressure, and when the water pressure of tap water is unstable, the pressure stabilizing valve 72 can stabilize the water pressure of tap water to be not more than a preset water pressure value, so that the stability of the water pressure of the micro-nano bubble liquid generation system 100 is ensured, and the safety and the reliability of the micro-nano bubble liquid generation system 100 are improved.
When the micro-nano bubble liquid generating system 100 is used, water enters the mixing cavity 16 of the air dissolving device 1 through the liquid inlet 12, air becomes air with higher pressure after passing through the inflator pump 52, the air enters the mixing cavity 16 of the air dissolving device 1 through the air inlet 11 to enable the mixing cavity 16 to contain sufficient amount of gas, the water and the air are fully mixed in the mixing cavity 16 of the air dissolving device 1 to form solution liquid, and the solution flows out through the liquid outlet 13 and then passes through the micro-nano bubble generator 41 to become micro-nano bubble water for users to use.
According to the micro-nano bubble liquid generating system, the water inlet valve 74 and the pressure stabilizing valve 72 are arranged on the liquid inlet flow path 7, the stability of water inlet pressure is improved, the inflator pump 52 is arranged on the air inlet gas path 5, the quality and the generating efficiency of micro-nano bubble water are improved, the overall structure of the micro-nano bubble liquid generating system 100 is simple, the use of parts is simplified, the production cost is reduced, the product cost performance is improved, and the experience effect of a user is optimized.
Alternatively, the feed valve 74 and the pressure maintaining valve 72 are connected in series to the feed flow path 7, and two feed flow paths 7 may be provided.
Alternatively, as shown in fig. 1 and 2, both ends of the feed valve 74 and the pressure maintaining valve 72 are connected in parallel and then connected in series to the feed liquid flow path 7, and at this time, the feed valve 74 and the pressure maintaining valve 72 may be connected in sequence through the same feed liquid flow path 7. That is, the upper end of the feed valve 74 and the upper end of the pressure maintaining valve 72 are connected in parallel, the lower end of the feed valve 74 and the lower end of the pressure maintaining valve 72 are connected in parallel, and the feed valve 74 and the pressure maintaining valve 72 connected in parallel are connected in series with the liquid inlet flow path 7.
Further, as in the second aspect example of fig. 4-5, the inlet valve 74 is a two-position three-way valve 75, the two-position three-way valve 75 having two outlet water paths arranged in parallel, and the pressure maintaining valve 72 connected in series to one of the two outlet water paths.
In a particular example, a pressure maintaining valve 72 may be connected in series in the left side outlet water circuit. Thereby simplifying the structure of the micro-nano bubble liquid generating system 100 and reducing the cost. The two-position three-way valve 75 has an AB path or an AC path, as shown in fig. 6, when air needs to be introduced into the mixing chamber 16, the AC path is closed, the AB path is opened, the pressure stabilizing valve 72 is opened, and at this time, the liquid can still be fed into the liquid inlet 12 toward the air dissolving device 1, so that the liquid outlet 13 of the air dissolving device 1 can still output a certain amount of liquid. When the mixing chamber 16 needs to dissolve gas, the AC passage is opened and the AB passage is closed, the inflator 52 stops inflating, at this time, the liquid entering from the AC passage flows into the mixing chamber 16 through the liquid inlet 12, so that the gas space in the mixing chamber 16 is occupied, the pressure of the mixing chamber 16 is increased, and the gas is further promoted to be dissolved in the liquid to form the gas-dissolved liquid.
Still alternatively, in the case where the air intake assembly 50 is only the inflator 52 in the present invention, the liquid path pressure regulating valve assembly 70 is not limited to the water inlet valve 74 and the pressure maintaining valve 72, for example, in the third aspect example in fig. 7 to 8, the liquid path pressure regulating valve assembly 70 includes an adjustable pressure maintaining valve 76, and the adjustable pressure maintaining valve 76 can change its own water flow rate by changing its own internal channel flow cross section or closing its internal channel, so as to adjust the liquid inlet pressure of the liquid inlet 12.
As shown in fig. 9, when the air dissolving device 1 needs to intake air, the adjustable pressure stabilizing valve 76 adjusts the pressure thereof to P1, so as to output a smaller flow rate, and gradually enlarge the space for accommodating air in the mixing chamber 16, thereby facilitating the air filling of the inflator 52 into the mixing chamber 16; when the air dissolving device 1 needs to dissolve air, the adjustable pressure stabilizing valve 76 adjusts the pressure to be P1-P2, and P2 is greater than P1, so that the space for accommodating air in the mixing cavity 16 is gradually reduced, and the pressure in the mixing cavity 16 is increased, so that the air is quickly dissolved in liquid to form air-dissolved liquid.
Advantageously, the air pressure pumped by inflator 52 is not less than the lower threshold of the adjustable pressure range of adjustable pressure maintaining valve 76. That is, the air pressure pumped by inflator 52 is greater than or equal to the lower threshold of the adjustable pressure range of adjustable pressure maintaining valve 76. Therefore, after the water pressure is reduced, air can be pumped into the mixing cavity 16, the water inlet does not need to be turned off, and the use feeling of a user is improved.
Advantageously, the upper threshold of the adjustable pressure range of adjustable pressure maintaining valve 76 is greater than the value of the air pressure pumped by inflator 52. That is, the amount of air pressure pumped by inflator 52 is less than the upper threshold of the adjustable pressure range of adjustable pressure stabilizing valve 76. Thus, it is avoided that the air pressure pumped by the inflator 52 is too high to feed water into the mixing chamber 16.
It should be noted here that the adjustable pressure stabilizing valve 76 can adjust the pressure stabilizing range, which is generally between 0.05MPa and 0.5 MPa.
Optionally, the adjustable pressure stabilizing valve 76 may be two-stage pressure regulating, the adjustable pressure stabilizing valve 76 may also be multi-stage pressure regulating, and the adjustable pressure stabilizing valve 76 may also be stepless pressure regulating. Therefore, the water inlet pressure can be conveniently adjusted, and the use is convenient.
Of course, the adjustable pressure maintaining valve 76 of the present invention may be disposed at the front end of the liquid inlet 12 together with the water inlet valve 74 instead of the conventional pressure maintaining valve 72 described above.
Alternatively, in the case where the air intake assembly 50 of the present invention is the inflator 52, the pressure regulating valve assembly 70 is not limited to the intake valve 74 and the pressure maintaining valve 72, and as shown in the fourth example of fig. 12 to 13, the pressure regulating valve assembly 70 includes: the pressure regulating valve 77 is connected in series to the liquid inlet flow path 7, and the outlet water pressure of the pressure regulating valve 77 is adjustable between an upper threshold and a lower threshold. That is to say, the liquid inlet flow path 7 is connected in series with the pressure regulating valve 77, the pressure regulating valve 77 has an upper threshold and a lower threshold, and the pressure regulating valve 77 can be regulated between the upper threshold and the lower threshold, so that the water inlet pressure is not less than the lower threshold and not greater than the upper threshold, the water inlet pressure is convenient to regulate, the air is easily inflated into the air dissolving device 1 when the water inlet pressure is reduced, and the content of micro-nano bubbles in water can be increased when the water inlet pressure is increased. As shown in fig. 14, when air needs to be supplied into the mixing chamber 16, the pressure regulating valve 77 is switched from the high-pressure position to the low-pressure position, so that the water outlet pressure is at the lower threshold value, and the liquid in the liquid inlet 12 enters the air dissolving device 1 at a small flow rate, at which time the air pump 52 is turned on and inflates air into the mixing chamber 16, so that the mixing chamber 16 is filled with the required air; when gas needs to be dissolved in the mixing chamber 16, the pressure regulating valve 77 is switched from a low-pressure gear to a high-pressure gear, so that the water outlet pressure is an upper valve value, the liquid entering the gas dissolving device 1 from the liquid inlet 12 is large in flow, at the moment, the inflator 52 is closed, and under the condition that the liquid in the mixing chamber 16 is continuously increased, the pressure in the mixing chamber 16 is increased, so that the gas is dissolved in the liquid to form gas-dissolved liquid.
In some embodiments of the present invention, as shown in the first aspect example in fig. 1 to 2, the second aspect example in fig. 4 to 5, the third aspect example in fig. 7 to 8, the fourth aspect example in fig. 12 to 13, the sixth aspect example in fig. 19, 20, 21, and the eighth aspect example in fig. 26, 27, and 28, the liquid outlet 13 is formed at the bottom of the gas dissolving device 1, the liquid inlet 12 is formed at the top or upper portion of the gas dissolving device 1, and the gas inlet 11 is formed at the top, bottom, or side wall of the gas dissolving device 1. That is to say, the air inlet 11 may be formed at the top of the air dissolving device 1, the air inlet 11 may also be formed at the bottom of the air dissolving device 1, the air inlet 11 may also be formed at the side wall of the air dissolving device 1, the liquid inlet 12 may be formed at the top of the air dissolving device 1, the liquid inlet 12 may also be formed at the upper part of the air dissolving device 1, and the liquid outlet 13 is formed at the bottom of the air dissolving device 1. Therefore, different use scenes can be met according to different user requirements, and the method is flexible and convenient.
As shown in fig. 11, the liquid inlet 12 is formed at the top of the air dissolving device 1, and can increase the flow velocity of water flow and increase the air bubble content of the air bubble mixed flow; the air inlet 11 is formed at the top of the air dissolving device 1, so that the structure is simple and the assembly is convenient; the liquid outlet 13 is formed in the bottom of the gas dissolving device 1, and by utilizing the gravity of water and the pressure in the gas dissolving device 1, the water can smoothly flow out without additionally arranging parts, water does not stay for a long time, the water quality is influenced, and the human health is damaged.
In other examples, it is also not limited to providing the liquid inlet 12 and the gas inlet 11 on the air dissolving device 1, and as shown in the fifth aspect example in fig. 16-17, the seventh aspect example in fig. 22, 23 and 24, and the ninth aspect example in fig. 29, 30 and 31, the liquid inlet 12 and the gas inlet 11 may be combined into a merging port 82 to communicate with the mixing chamber 16 of the air dissolving device 1. Therefore, in these examples, either the intake liquid or the intake air flows into the mixing chamber 16 through the merging opening 82, so that the opening required to be formed in the air dissolving device 1 is saved, the sealing performance of the air dissolving device 1 is improved, and the structure of the air dissolving device 1 is simplified.
In some embodiments of the present invention, the micro-nano bubble liquid generating system 100 further includes: and the controller 3 is in communication connection with the inflator 52 and is used for controlling the inflator 52 to start and stop, so as to control the inflator 52 to supply air to the mixing chamber 16 after being started, or control the inflator 52 to stop supplying air to the mixing chamber 16 after being stopped. Alternatively, the controller 3 is connected to the pump body 53 of the air intake assembly 50 for controlling the start and stop of the pump body 53, so as to control the pump body 53 to pump liquid and promote air intake in the mixing chamber 16 when opened, and control the pump body 53 to control dissolved air in the mixing chamber 16 when closed. Through the effect of controller 3, can simplify the operating procedure of micro-nano bubble liquid generation system 100, reduce the operation degree of difficulty, convenient to use, intelligent degree height.
In some embodiments of the present invention, the micro-nano bubble liquid generating system 100 further includes: the water flow sensor 71 and the water flow sensor 71 are disposed on the liquid inlet flow path 7 to detect the liquid inlet flow rate of the liquid inlet flow path 7, so that whether liquid flows through and the flow rate of the liquid flowing through can be detected in real time. The water flow sensor 71 is in communication connection with the controller 3, so that the controller 3 can accurately control the water inflow and the water inflow pressure in the mixing chamber 16, resources are saved, and sufficient liquid can be ensured to meet dissolved air.
As in the examples shown in fig. 3, 6, 9, 14, 18, the controller 3 is configured to control activation of the inflator 52 to inflate when the water flow signal is detected by the water flow sensor 71. As in the example shown in fig. 25, 32, the controller 3 is configured to control the pump body 53 to start pumping when the water flow sensor 71 detects a water flow signal. Thereby enabling the controller 3 to control the inflator 52 or the pump body 53 to perform air intake in the mixing chamber 16 when the water flow sensor 71 detects a water flow signal.
In order to further improve the control necessity of air intake, the micro-nano bubble liquid generation system 100 further includes a water outlet switch 61, the water outlet switch 61 is disposed on the water outlet flow path 6 of the air dissolving device 1, the water outlet switch 61 is in communication connection with the controller 3, and when the water outlet switch 61 is opened, the controller 3 controls the mixing chamber 16 to be in an air intake state. That is, when the water outlet switch 61 is turned on, it indicates that the water end connected to the water outlet flow path 6 needs to use water, and at this time, the liquid will pass through the liquid inlet flow path 7, so that when the water flow sensor 71 detects that the liquid passes through, the controller 3 can control the pump body 53 or the inflator 52 to operate, and the air inlet path 5 is promoted to inlet air into the mixing chamber 16.
Alternatively, the water flow sensor 71 is provided downstream of the liquid path pressure regulating valve assembly 70 in the direction of water flow, for example, on the inlet flow path 7 and in front of the inlet 12; for example, the flow path is provided on the junction channel 8 and in front of the junction 82. Alternatively, the water flow sensor 71 is provided upstream of the liquid passage pressure regulating valve assembly 70 in the water flow direction. Therefore, the installation of a user is facilitated according to different requirements, the operation is convenient, and the application range is enlarged.
In other examples, the water flow sensor 71 may be disposed on the liquid outlet flow path 6, wherein in the example where the pump body 53 is disposed on the liquid outlet flow path 6, the pump body 53 is used as a reference, and the water flow sensor 71 may be disposed on the front side of the pump body 53 and on the rear side of the liquid outlet 13; or, the water flow sensor 71 can be arranged on the rear side of the pump body 53 and positioned on the front side of the water outlet switch 61, the arrangement position of the water flow sensor 71 can be flexibly selected according to actual needs, and convenience in installation of a user is improved.
When the air dissolving device 1 is in the process of air dissolving operation for a certain time, the liquid outlet flow path 6 will continuously discharge a certain amount of air dissolving liquid, the water flow sensor 71 will continuously detect the water flow, and the water outlet switch 61 is also continuously in the on state, at this time, the circulation control program can be executed through the further control program, so as to realize liquid discharging and air intake in the middle of operation.
Further, the controller 3 is also in communication connection with the liquid path pressure regulating valve assembly 70 and the air intake assembly 50, respectively, and the controller 3 is configured to control the liquid path pressure regulating valve assembly 70 to switch to the low water pressure state when the accumulated water flow of the water flow sensor 71 is greater than a first preset flow L1 or the accumulated service time of the water flow sensor 71 is greater than a first preset time T4, and the controller 3 controls the air intake assembly 50 to operate to enter the air intake state, so that the liquid discharge and air intake process of the air dissolving device 1 is realized during operation, air in the mixing chamber 16 is supplemented, and the content of gas in the air dissolving liquid is increased. As shown in fig. 18, during the liquid discharge and air intake, the liquid path pressure regulating valve assembly 70 can be controlled to operate at a low water pressure state, i.e., a low water flow operation time T2, and the inflator 52 can be controlled to operate at a low water flow operation time T3, so as to achieve the air intake of the mixing chamber 16.
It should be noted that, here, the control of the operation of the intake assembly 50 includes the operation of controlling the pumping operation of the pump body 53 and/or the operation of controlling the charging operation of the inflator 52, and the control operation may be performed according to the components designed in the respective examples.
Alternatively, after the water outlet switch 61 is turned off, the controller 3 is configured to control the mixing chamber 16 to be in the air inlet state again when the water outlet switch 61 is turned off for a time period longer than a second preset time T5 and the water outlet switch 61 is turned on again, that is, the water flow sensor 71 does not detect that the water flow rate (no water flow signal) is longer than T5 continuously, so that a certain amount of dissolved air liquid is always kept in the mixing chamber 16.
In other examples, when the water outlet switch 61 is turned on again when the water outlet switch 61 is turned off last time and the accumulated water flow rate of the water flow sensor 71 is greater than the second preset flow rate L2, the controller 3 controls the mixing chamber 16 to be in the air inlet state again, so that the air in the mixing chamber 16 is supplemented.
In some embodiments of the present invention, the micro-nano bubble liquid generating system 100 further includes a liquid level sensor 161, the liquid level sensor 161 is in communication connection with the controller 3, the liquid level sensor 161 is configured to detect a liquid level height of the liquid in the mixing chamber 16, so as to accurately determine the liquid level in the mixing chamber 16, and further determine the pressure in the mixing chamber 16 according to the liquid level, which is beneficial to more accurately determining and controlling a liquid discharge, air intake, and air dissolution process in the mixing chamber 16, so as to further ensure the quality of the air dissolution liquid flowing out from the liquid outlet flow path 6, provide reliable guarantee for the subsequent formation of micro-bubble water, and ensure the air content density of the micro-bubble water.
Optionally, when the liquid level sensor 161 is disposed at a lower position of the mixing chamber 16, when the liquid level sensor 161 detects a water flow signal, the controller 3 enters a liquid discharge and air intake process, at this time, the controller 3 controls the liquid path pressure regulating valve assembly 70 to operate to reduce its water flow, and the controller 3 further controls the pump body 53 to pump liquid to make the air dissolving device 1 intake air.
As shown in fig. 25 and 32, the controller 3 is configured to control the air intake assembly 50 to stop operating when the liquid level is lower than the lower limit of the preset liquid level threshold, in these examples, since the pump body 53 will continuously pump liquid in the early stage, the liquid outlet flow path 6 will continuously discharge dissolved gas liquid outwards, so that the liquid level in the mixing chamber 16 will continuously decrease, the space capable of accommodating the gas volume in the mixing chamber 16 increases, the pressure in the mixing chamber 16 decreases, and the gas in the air intake path 5 will continuously fill the mixing chamber 16, and by controlling the air intake assembly 50 to stop operating, the amount of gas finally filled into the mixing chamber 16 can be controlled, so as to ensure that the gas filled into the mixing chamber 16 is sufficient, and ensure that a certain amount of liquid remains in the mixing chamber 16, thereby effectively preventing the water end from being cut off.
Further optionally, after the air intake of the mixing chamber 16 is completed, the controller 3 is further configured to keep the air intake assembly 50 stopped and control the liquid path pressure regulating valve assembly 70 to switch to a high water pressure state when the liquid level is lower than the lower limit value of the preset liquid level threshold, where the liquid path pressure regulating valve assembly 70 is in a high flow rate state, so that the liquid path pressure regulating valve assembly 70 quickly supplies liquid to the mixing chamber 16, thereby increasing the pressure in the mixing chamber 16 and promoting the gas in the mixing chamber 16 to be dissolved in the liquid as soon as possible. As shown in fig. 25 and 32, in these examples, the pump body 53 is closed, facilitating efficient formation of the liquid solution in the mixing chamber 16. The level sensor 161 in these examples is suitably located at a lower portion of the mixing chamber 16.
Optionally, when the liquid level sensor 161 is disposed at the middle and upper portion of the mixing chamber 16, the controller 3 is configured to control the inflator 52 to inflate the air dissolving device 1 when the liquid level detected by the liquid level sensor 161 is at the preset liquid level height threshold, and the inflation may be performed by discharging liquid and intaking air through the pump body 53, or the inflation may be performed by discharging liquid and intaking air through the pump body 53 and simultaneously inflating high-pressure air through the inflator 52, so as to refill the mixing chamber 16 with the required gas. In the present invention, the requirement for filling gas into the mixing chamber 16 can be determined by determining and detecting the height of the liquid level in the mixing chamber 16.
The preset liquid level height in the invention can be selected and flexibly set according to the actual situation.

Therefore, the micro-nano bubble generator 41 may be provided with a gap water passing channel besides the micro-nano bubble water micro-channel, when the water pressure of the inlet water is low, the gap water passing channel may be turned on to increase the water output of the micro-nano bubble generator 41, and when the water pressure of the inlet water is high, the gap water passing channel may be turned off to allow the micro-nano bubble water to flow out of the micro-nano bubble water micro-channel of the micro-nano bubble generator 41.

That is, the ratio between the width dimension of the mixing chamber 16 and the width dimension of the dissolved water chamber in the left-right direction 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 bubble mixing cannot be generated in the mixing chamber 16, 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. 11, in the left-right direction, the ratio between the width of the mixing chamber 16 and the width 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, 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 bubbles have more content, 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 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 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.
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.
