Figure 1 As shown, it includes a tap water source 1, an air inlet 2, a PCB composite filter element 7, an ejector 3, a self-priming pump 4, and a faucet 5. The tap water source 1 is connected to the first water inlet D of the PCB composite filter element 7 through a pipeline. A first pure water pipeline 6 is provided between the PCB composite filter element 7 and the faucet 5. The first pure water outlet A of the PCB composite filter element is connected to the first pure water pipeline 6. The first pure water pipeline 6 is directly connected to the pure water inlet of the faucet 5.

[0044] Continue as Figure 1 As shown, a second purified water outlet B is also provided on the PCB composite filter element 7. The second purified water outlet B is connected to the first purified water pipeline 8. The first purified water pipeline 8 is sequentially connected to a first tee connector 9, a first control valve 10, a raw water TDS probe 11, and a second tee connector 12. The branch connector of the first tee connector 9 is connected to the inlet of the jet injector 3 through a purified water branch pipeline 13. A second pressure reducing valve 14 is installed on the purified water branch pipeline 13. Furthermore, the air inlet 2 is connected to the air inlet of the jet injector 3 via the air inlet pipe 15.

[0045] Continue as Figure 1As shown, a fourth three-way connector 20 is connected to the output port of the self-priming pump 4. One branch of the fourth three-way connector 20 is connected to a purified water pipeline 21. The purified water pipeline 21 is connected to an RO reverse osmosis membrane filter element 22 for reverse osmosis filtration of water. A third control valve 23 is installed on the purified water pipeline 21 to control the opening and closing of the pipeline. The pure water outlet of the RO reverse osmosis membrane filter element 22 is connected to a fifth three-way connector 24 through a pipeline. One branch of the fifth three-way connector 24 is connected to the second inlet C of the PCB composite filter element 7 through a first sterilization and impurity removal pure water pipeline 25. After filtration, purification and improvement of taste, the purified water is input into the first pure water pipeline 6 through the first pure water outlet A on the PCB composite filter element 7. The first sterilization and impurity removal pure water pipeline 25 is connected in sequence to a first check valve 26, a first high-pressure switch 27 and a pure water TDS probe 28. The other branch of the fifth three-way connector 24 is connected to the third three-way connector 19 and the self-priming pump 4 through a second pure water pipeline 29.

The second pure water pipeline 29, the fourth control valve 30, and the second check valve 31 are used to flush the reverse osmosis membrane of the RO reverse osmosis membrane filter element 22 when the faucet is closed and the machine is stopped. During normal water production, the fourth control valve 30 is in the closed state.

[0047] Example 2

[0048] like Figure 2As shown, the embodiment differs from the first embodiment in that a second high-pressure switch 53 is further arranged on the ultrafine bubble water pipeline 33 between the bubble generator module 32 and the fifth control valve 34, for detecting the pressure change between the bubble generator module 32 and the bubbler 35 to control the opening and closing of the first control valve 10. When the second high-pressure switch 53 detects the pressure change between the bubble generator module 32 and the bubbler 35, the opening and closing of the first control valve 10 is controlled to adjust the pressure between the back end of the self-priming pump and the bubbler. That is, when the second high-pressure switch 53 detects low pressure, such as 4.0-7.0 kg, the air inlet 2 can introduce air, and the air and water are mixed to form ultrafine bubble water. When the detected pressure is close to 7.5 kg, due to the suction force of the self-priming pump 4, the water pressure is too high, and the self-priming pump 4 cannot suck in air. At this time, the first control valve 10 is closed. When the pressure at the back end of the self-priming pump 4 is close to 4.0-7.0 kg, the first control valve 10 is opened again, so that the pressure at the back end of the self-priming pump 4 is established at 4-8 kg, and the pressure at the back end of the self-priming pump 4 is increased. The pump pressure changes from 4 kg to 8 kg, and the water outlet will not have obvious shaking.

[0049] As shown in the above two embodiments, the kitchen ultrafine bubble large-flux water purification system corresponds to a water purifier, such as Figure 3 and Figure 4 As shown, the water purifier comprises a shell a, a main control board 39, a fluidic device 3, a self-priming pump 4, a PCB composite filter element 7, and an RO reverse osmosis membrane filter element 22. The PCB composite filter element 7 and the RO reverse osmosis membrane filter element 22 are stacked vertically and horizontally installed on the top side upper space of the shell a. The front side of the shell a is provided with an inner lining plate 40 for fixing the PCB composite filter element 7 and the RO reverse osmosis membrane filter element 22. The rear side of the shell a is provided with a waterway plate 41 for facilitating waterway layout and connection, a waterway plate cover 42 for sealing the waterway plate 41, and a rear cover 43 for sealing the back end face. The bottom side of the shell a is provided with a base 44, and the base 44 is provided with a main body frame 45 for fixing the main control board 39, the fluidic device 3, the self-priming pump 4, the PCB composite filter element 7, and the RO reverse osmosis membrane filter element 22. The left and right sides of the shell a are respectively provided with a left side cover plate 46 and a right side cover plate 47 connected and fixed to the main body frame 45. The top side of the shell a is provided with a top cover 48 buckled to the top side of the main body frame 45.

[0050] As shown in the above two embodiments, the water purifier corresponds to a water purifier, such as Figure 3 and Figure 4 As shown, the main control board 39 is installed at the bottom front end of the main body frame 45. The fluidic device 3 is installed and fixed at the bottom middle rear side of the main body frame 45 through an upper fixing frame 49, a lower fixing frame 50, and a side rib plate 51. The self-priming pump 4 is arranged at the front lower side of the fluidic device 3 and installed on the bottom side of the main body frame 45 through a pump support 52. The inner lower part of the waterway plate 41 is provided with a first check valve 26, a first high-pressure switch 27, a pure water TDS probe 28, and a second pressure reducing valve 14 from top to bottom.

[0051] The working principle of the kitchen ultra-micro bubble large-flow water purification system and the water purifier thereof is as follows:

[0052] When pure water is made, tap water is first pretreated by the PCB composite filter core 7, the second control valve 16, the fourth control valve 30 and the fifth control valve 34 are closed, the first control valve 10 and the third control valve 23 are opened, the self-priming pump 4 works, and then the water passes through the RO reverse osmosis membrane filter core 22, the pure water flows out from the pure water outlet of the PCB composite filter core 7, and is discharged from the faucet 5 through the first pure water pipeline 6.

[0053] When the pure water is washed, the tap water is first pretreated by the PCB composite filter core 7, the second control valve 16 is closed, the first control valve 10, the third control valve 23 and the fourth control valve 30 are opened, the self-priming pump 4 works, and the pure water reciprocates back to the front of the self-priming pump 4 through the second pure water pipeline 29, mixes the prepared water with the purified water, dilutes the impurities in front of the RO reverse osmosis membrane filter core 22, reduces the TDS in the reverse osmosis membrane, and solves the problem of high TDS of the first cup of water.

[0054] When ultra-micro bubble sparkling water is needed, the ultra-micro bubble sparkling water making function is opened, a signal is sent to the main control board 39 of the host through the faucet 5, the ultra-micro bubble sparkling water is taken, the tap water is first pretreated by the PCB composite filter core 7, the third control valve 23 and the fourth control valve 30 are closed, the second control valve 16 and the fifth control valve 34 are opened respectively, and the first control valve 10 is opened, the opening time is ≤5 seconds, and the self-priming pump 4 works; the first control valve 10 is opened to make the purified water enter; the bubble generating module 32 passes through the flow limiting aperture, the Venturi tube in the jet device 3 forms a water-air mixing cavity, and the ultra-micro bubble sparkling water is formed; moreover, the pressure between the rear end of the self-priming pump 4 and the bubbler 35 is formed, the pressure between the self-priming pump 4 and the bubble generating module 32 is established, the pressure at the rear end of the self-priming pump 4 is greater than 4.0 kg, and the water outlet of the faucet 5 slightly shakes or does not shake; the ultra-micro bubble sparkling water effectively cleanses fruit and vegetable residues, restores the cleanliness of food, quickly cleanses tableware, easily removes oil and bacteria, and effectively improves the quality of life.

[0055] During the working process, the Venturi tube in the jet device 3 makes water and air form ultra-micro bubble water through the pressure of the self-priming pump 4, the ultra-micro bubble water is mixed with the purified water, and the mixture is discharged through the bubbler 35 and the faucet 5.

[0056] In addition, in the case that the first control valve 10 is closed, the pressure between the back end of the self-priming pump 4 and the bubbler 35 is lower than 4-7 kg when the water and air are mixed through the pressure reducing valve, the jet 3, and the self-priming pump 4. In the working process of the embodiment, when the third control valve 23 and the fourth control valve 30 are closed and the second control valve 16 is opened, the first control valve 10 is controlled to be opened and closed in a pulse mode to adjust the pressure between the back end of the self-priming pump 4 and the bubbler 35, and to control the pressure change of the back end of the self-priming pump 4. When the pressure is low, such as 4.0-7.0 kg, the air inlet 2 can introduce air, and the air and water are mixed to form the ultra-micro bubble bubble water. When the pressure is close to 7.5 kg, the self-priming pump 4 cannot suck air due to the excessive water pressure caused by the suction force of the self-priming pump 4, and the first control valve 10 is closed at this time. When the pressure of the back end of the self-priming pump 4 is close to 4.0-7.0 kg, the first control valve 10 is opened again to make the pressure of the back end of the self-priming pump 4 be 4-8 kg, so that the pressure of the back end of the self-priming pump 4 is increased, and the water outlet will not be obviously shaken. In addition, when the ultra-micro bubble bubble water prepared by the bubble generating module 32 enters the bubbler 35, the pressure is released, and one million bubbles with a radius of 20-50 microns can be released in 1 mL of water. Each micro-bubble generates energy at the moment of pressure release, increases friction impact, and can effectively clean various food materials such as fruits and vegetables, and kitchen utensils, to ensure safe eating or using.

[0057] The above-described embodiments are only the preferred embodiments of the present application, and do not limit the scope of the present application. Any changes made according to the shape, structure, and principle of the present application, and other changes made without departing from the spirit of the present application, should be included in the protection scope of the present application.
