[0051] Embodiment 1:

[0052] like Figure 1 As shown, this embodiment provides a micro-bubble water purifier, which includes a water inlet assembly, which includes a water-gas ratio adjustment mechanism 11 and a variable frequency booster pump 12 sequentially arranged on a water inlet pipeline 10 along the water flow direction, and the inlet of the water inlet pipeline 10 is connected to the tap. An air inlet assembly is arranged between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12, and the air inlet assembly is connected to the air dissolving tank 14. The gas of the air inlet assembly can enter the air dissolving tank 14, so that the negative pressure before the pump is stable, forming stable bubble water.

[0053] In this embodiment, the air intake assembly is connected to the water inlet pipeline 10 between the water-gas ratio adjustment mechanism 11 and the dissolved air tank 14. The air intake assembly is connected to the dissolved air tank 14 through the water inlet pipeline 10. This connection method is relatively simple.

[0054] Specifically, the air intake assembly includes an air intake pipeline 31 and an air pump 32. The air pump 32 is connected to the inlet end of the air intake pipeline 31, and the outlet end of the air intake pipeline 31 is connected to the water intake pipeline 10 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12. The air pump 32 is connected to the water intake pipeline 10 through the air intake pipeline 31, and can transport gas into the water intake pipeline 10 to merge with water.

[0055] Furthermore, a one-way valve 33 is provided on the air intake pipe 31. The one-way valve 33 allows gas to enter the water intake pipe 10 from the air pump 32 through the air intake pipe 31 to avoid reverse flow. It can prevent the water in the water intake pipe 10 from flowing back to the air pump 32 through the air intake pipe 31, thereby improving the working reliability of the micro-bubble water purifier.

[0056] like Figure 1 As shown, the micro-bubble water purifier also includes a bubble water generating component, which includes a bubble water pipe 21 and a bubbler 22. One end of the bubble water pipe 21 is connected to the end of the water inlet pipe 10, and the other end of the bubble water pipe 21 is a water end for bubble water. A bubble water faucet can be provided at the water end for bubble water, so that it is convenient for users to directly use bubble water and improve the user's operating comfort. The bubbler 22 is provided on the bubble water pipe 21, and micro-bubble water is prepared by the bubbler 22. Since the bubbles in the micro-bubble water have special properties such as high surface charge potential, large specific surface area, and negative surface charge, the bubbles show good adsorption effect on suspended matter and oils, so the bubbles have strong adsorption and the bubble water has a good washing effect.

[0057] Furthermore, a micro-bubble water solenoid valve 23 is provided upstream of the bubble water pipe 21 and controls the opening and closing of the bubble water pipe 21 by the micro-bubble water solenoid valve 23 so that water in the water inlet pipeline 10 enters the bubble water pipe 21 to prepare micro-bubble water.

[0058] Optionally, the water inlet assembly further includes a pre-treatment filter element 16, which is disposed on the water inlet pipeline 10 and is located upstream of the water-gas ratio regulating mechanism 11, and is used to coarsely filter large particles of impurities such as silt and rust in the tap water to prevent large particles of impurities from entering the subsequent pipelines, preventing the subsequent pipelines and equipment from being blocked or damaged, and protecting the subsequent pipelines and equipment. The specific structure of the pre-treatment filter element 16 belongs to the prior art and will not be described in detail here.

[0059] like Figure 1As shown, the microbubble water purifier also includes a clean water generating component, which includes a filter element 42 arranged on a clean water pipeline 41, one end of the clean water pipeline 41 is connected to the end of the water inlet pipeline 10, and the other end of the clean water pipeline 41 is a clean water end, and a clean water faucet can be set at the clean water end, so that the user can directly use the clean water and improve the user's operating comfort. In this embodiment, the filter element 42 is an RO membrane filter element, which can have a good filtering effect on water.

[0060] Furthermore, a water inlet solenoid valve 43 is provided upstream of the filter element 42 of the water purification pipeline 41, and the water inlet solenoid valve 43 is used to control the on-off of the water purification pipeline 41 and the water inlet pipeline 10, so that the water inlet solenoid valve 43 can be closed when preparing micro bubble water to prevent water from flowing into the water purification pipeline 41 and affecting the preparation of micro bubble water. When it is necessary to prepare purified water, the water inlet solenoid valve 43 is opened and the micro bubble water solenoid valve 23 is closed to prevent water from flowing into the bubble water pipe 21.

[0061] Optionally, a post-processing filter element 45 is provided downstream of the filter element 42, and the post-processing filter element 45 is used to absorb foreign color and odor substances, improve the taste, and further improve the purification effect of purified water. A water purification solenoid valve 44 is provided downstream of the post-processing filter element 45, and the water purification solenoid valve 44 is used to control the outflow and use of purified water, and the control is more flexible.

[0062] like Figure 1 As shown, the microbubble water purifier also includes a concentrated water discharge device, which includes a concentrated water control valve 52 arranged on a concentrated water pipeline 51, and the concentrated water pipeline 51 is connected to the concentrated water outlet end of the filter element 42. The concentrated water discharge device is used to discharge the waste water formed after filtering by the filter element 42 from the concentrated water pipeline 51. The concentrated water control valve 52 can control the on-off of the concentrated water pipeline 51, so as to improve the switching reliability of the concentrated water pipeline 51 function.

[0063] like Figure 1 As shown, a first pressure gauge 13 is provided on the water inlet pipeline 10 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12. The first pressure gauge 13 can detect the actual water pressure in the water inlet pipeline 10 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12.

[0064] Optionally, an air dissolving tank 14 is provided on the water inlet pipeline 10 between the water-gas ratio regulating mechanism 11 and the variable frequency booster pump 12, and the air inlet assembly is connected to the air dissolving tank 14. The air dissolving tank 14 can stabilize the negative pressure before the pump, so that the gas can be better dissolved in water, and the content of gas in the microbubble water can be increased. In this embodiment, the air dissolving tank 14 is arranged between the first pressure gauge 13 and the variable frequency booster pump 12, and the air inlet pipeline 31 of the air inlet assembly is connected to the water inlet pipeline 10 between the water-gas ratio regulating mechanism 11 and the first pressure gauge 13, so that the air inlet assembly is connected to the air dissolving tank 14 through the air inlet pipeline 31 and the water inlet pipeline 10, and this connection method is relatively simple. A second pressure gauge 15 is provided on the water inlet pipeline 10 downstream of the variable frequency booster pump 12. The second pressure gauge 15 is provided to detect the actual water pressure after the pump.

[0065] Optionally, the water-gas ratio adjustment mechanism 11 includes a flow control valve 111 and a pressure reducing valve 112 arranged in parallel. The flow control valve 111 controls the flow of the branch where it is located, thereby changing the distribution ratio of the flow of the branch where the flow control valve 111 and the pressure reducing valve 112 are located. The setting of the pressure reducing valve 112 plays a role in reducing pressure. Under the action of different flow rates, the pressure reducing degree of the pressure reducing valve 112 is different, thereby changing the pump front pressure of the variable frequency booster pump 12. When the pump front pressure reaches the preset value, the water-gas ratio of the microbubbles can be within the optimal range, ensuring the cleaning effect of the microbubble water.

[0066] The present embodiment also provides a control method for a microbubble water purifier, which is applied to the above-mentioned microbubble water purifier. The control method for the microbubble water purifier includes the following steps: measuring the pressure P1 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12; adjusting the water-gas ratio adjustment mechanism 11 according to the pressure P1, and making the pressure P1 equal to the preset pressure P10, so as to adjust the intake flow rate, so that the water-gas ratio of the microbubble water reaches the optimal ratio. By measuring the pressure P1 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12, adjusting the water-gas ratio adjustment mechanism 11 according to the pressure P1, and making the pressure P1 equal to the preset pressure P10, since the water pressure of the water inlet pipeline 10 between the water-gas ratio adjustment mechanism 11 and the variable frequency booster pump 12 is equal to the air pressure of the pipeline where the air inlet component is located, the intake flow rate can be adjusted, thereby making the water-gas ratio of the microbubble water reach the optimal ratio, and ensuring the cleaning effect of the microbubble water.

[0067] The water-gas ratio regulating mechanism 11 is used to adjust the air intake flow of the air intake component, and then the water pressure between the water-gas ratio regulating mechanism 11 and the variable frequency booster pump 12, that is, the pressure before the pump; the variable frequency booster pump 12 is used to adjust the water pressure in the water inlet pipeline 10 after the variable frequency booster pump 12 (that is, the pressure after the pump), and then adjust the water outlet flow rate of the microbubble water.

[0068] Optionally, the control method of the microbubble water purifier also includes: measuring the pressure P2 in the water inlet pipe 10 after the variable frequency booster pump 12, that is, the post-pump pressure, adjusting the variable frequency booster pump 12 according to the pressure P2, and making the pressure P2 equal to the preset pressure P20, thereby adjusting the water outlet flow rate of the microbubble water to meet different usage requirements.

[0069] like Figure 2 As shown, the control method of the microbubble water purifier includes the following steps:

[0070] S11. Select the water flow rate of the microbubble water.

[0071] The microbubble water purifier is provided with a variety of microbubble water outlet flow rates for users to choose from, which can be selected by users in the form of knobs or buttons. Users can choose different microbubble water outlet flow rates according to their usage needs. The specific structure belongs to the prior art and will not be repeated here.

[0072] S12, obtaining the corresponding pump post-pump pressure P20 and pump pre-pump pressure P10 of the variable frequency booster pump 12 according to the water outlet flow rate.

[0073] Since the outflow rate of the microbubble water is determined by the pressure after the variable frequency booster pump 12, the pressure after the variable frequency booster pump 12 P20 required to adjust the outflow rate of the microbubble water to the outflow rate value selected by the user can be obtained according to the outflow rate of the microbubble water selected by the user, and the preset pressure P10 for making the water-gas ratio reach the optimal ratio can be obtained according to the outflow rate. It should be noted that different outflow rates correspond to different preset pressures P20 after the variable frequency booster pump 12 and preset pressures P10 before the pump.

[0074] S13, the variable frequency booster pump 12 selects corresponding working parameters according to the preset pressure P20 to adjust the after-pump pressure of the variable frequency booster pump 12 to P20; adjust the water-gas ratio adjustment mechanism 11 to adjust the before-pump pressure of the variable frequency booster pump 12 to P10.

[0075] The control method of the microbubble water purifier can obtain the corresponding preset pressure P20 after the pump and the preset pressure P10 before the pump of the variable frequency booster pump 12 according to the water outlet flow rate of the microbubble water. The variable frequency booster pump 12 selects the corresponding working parameters according to the preset pressure P20 to adjust the pressure after the pump to P20, thereby obtaining the required water outlet flow rate; the pressure before the pump is adjusted to P10 by adjusting the water-gas ratio adjustment mechanism 11, so that the water-gas ratio of the microbubbles reaches the optimal ratio, thereby ensuring the cleaning effect of the microbubble water.

[0076] Specifically, the variable frequency booster pump 12 can adjust the pressure after the pump by changing the speed and duty cycle of the motor; the water-gas ratio adjustment mechanism 11 is composed of a flow control valve 111 (such as a stepper motor, etc.) and a pressure reducing valve 112 in parallel, and the distribution ratio of the incoming water in the parallel water channel is adjusted by changing the orifice opening of the flow control valve 111, thereby adjusting the pressure after the water-gas ratio adjustment mechanism 11 (i.e., the pressure before the pump).

[0077] In order to calculate P10 and P20, let the water flow rate be u, the air flow rate be v, the pressure of the first pressure gauge 13 be P10, and the pressure of the second pressure gauge 15 be P20. The air flow rate v of the air pump 32 corresponds to the load pressure P10 of the air pump 32, that is, v=v(P10). Generally, the air flow rate v and the load pressure P10 of the air pump 32 are in a quadratic function relationship, such as the pressure and flow curve of a certain air pump, see Figure 3 .

[0078] Considering that the microbubble water flow rate is generally between 1.5L / min and 5L / min, and the water-gas ratio range is (25:1) to (100:1), and the optimal water-gas ratio is (50:1), so the aeration flow rate v is less than 200mL / min, then within the working range of the air pump 32, the aeration flow rate v and the load pressure P10 of the air pump 32 are approximately linearly related, that is, v = a*P10+b, where a and b are constants, such as Figure 4 .

[0079] The water flow rate of the bubbler 22 corresponds to the pressure before the bubbler 22 (pressure after the pump) in a one-to-one correspondence. The water flow rate of the bubbler 22 is equal to the water flow rate u. The pressure before the bubbler 22 is equal to P20, so u = u (P20). The water flow rate of the bubbler 22 and the pressure are approximately linearly related. According to the test, the relationship is: u = c*P20 + d, where c and d are constants. Figure 5 .

[0080] The control method of the microbubble water purifier comprises the following steps:

[0081] When the user selects microbubble water and the water flow rate is u, the program first calculates the preset pressure P20 after the pump according to the formula u=c*P20+d, the optimal aeration flow rate is v=u / 50, and then calculates the preset pressure P10 before the pump according to the formula v=a*P10+b.

[0082] The control system of the microbubble water purifier controls the variable frequency booster pump 12 to open at the corresponding motor speed and duty cycle, controls the microbubble water solenoid valve 23 to open, and closes the water inlet solenoid valve 43, the water purification solenoid valve 44 and the concentrated water solenoid valve 53; adjusts the variable frequency booster pump 12 so that the pressure value after the pump is P20; adjusts the opening of the flow control valve 111 so that the pressure value before the pump is P10, and turns on the air pump 32.

[0083] When the user changes the microbubble water flow rate, just recalculate according to the above steps.

[0084] Embodiment 2:

[0085] This embodiment provides a micro-bubble water purifier, which is applicable to the control method of the micro-bubble water purifier in Embodiment 1. The difference between the micro-bubble water purifier in this embodiment and the micro-bubble water purifier in Embodiment 1 is that in this embodiment, Figure 6 As shown, a gas flow meter 34 is provided on the intake pipe 31, and the gas flow meter 34 is used to detect the gas flow in the intake pipe 31. When the flow on the intake pipe 31 adjusted according to the calculated pump front pressure P1 is different from the flow obtained by the gas flow meter 34, the gas flow in the intake pipe 31 is corrected by adjusting the flow control valve 111 to reduce the error.

[0086] like Figure 6 As shown, the bubble water generating assembly further includes a flow meter 24 disposed on the bubble water pipe 21, and the flow meter 24 is used to detect the liquid flow in the bubble water pipe 21. When the liquid flow in the bubble water pipe 21 adjusted according to the calculated post-pump pressure P2 is different from the flow obtained by the flow meter 24, the variable frequency booster pump 12 is adjusted to correct the liquid flow in the bubble water pipe 21 to reduce the error.

[0087] Embodiment three:

[0088] This embodiment provides a microbubble water purifier, which is applicable to the control method of the microbubble water purifier in the first embodiment. The difference between the microbubble water purifier in this embodiment and the microbubble water purifier in the first embodiment is that in the first embodiment, the air intake pipeline 31 of the air intake assembly is directly connected to the water intake pipeline 10, and the air intake assembly is connected to the air dissolving tank 14 through the water intake pipeline 10. In this embodiment, Figure 7 As shown, the air intake pipeline 31 of the air intake assembly is directly connected to the dissolved gas tank 14. In this embodiment, the outlet end of the air intake pipeline 31 is connected to the bottom of the dissolved gas tank 14. The air intake pipeline 31 directly inputs the gas into the dissolved gas tank 14, which is convenient for fully blending the gas and water and increasing the ratio of gas dissolved in water.
