[0002] The function of existing water purifiers is mainly to provide purified drinking water. Its function is still relatively simple.

[0044] Figure 1 Schematic diagram of the structure of a micro bubble water purifier provided by the embodiment of the utility model. Figure 1As shown, the microbubble water purifier includes a water inlet pipe 10, an air inlet pipe 20, a water-gas mixing pipe 30 and an RO filter pipe 40; the RO filter pipe 40 includes an RO membrane filter element 41; the input end of the water-gas mixing pipe 30 is connected to the output end of the water inlet pipe 10 and the output end of the air inlet pipe 20 respectively; the output end of the water-gas mixing pipe 30 is connected to the input end of the RO filter pipe 40.

[0045] Specifically, the microbubble water purifier includes a water inlet pipe 10, an air inlet pipe 20, a water-gas mixing pipe 30 and an RO filter pipe 40. Among them, the RO filter pipe 40 includes an RO membrane filter element 41, and the RO membrane filter element 41 can input the pre-filtered water to be processed into pure water and output it. The input end of the water-gas mixing pipe 30 is connected with the output end of the water inlet pipe 10 and the output end of the air inlet pipe 20 respectively, so that the water output from the water inlet pipe 10 can enter the water-gas mixing pipe 30, and / or, the gas output from the air inlet pipe 20 can enter the water-gas mixing pipe 30. The output end of the water-gas mixing pipe 30 is connected with the input end of the RO filter pipe 40, so that the output of the water-gas mixing pipe 30 can flush the RO membrane filter element 41 in the RO filter pipe 40. In one specific embodiment, if the water output from the water inlet pipe 10 and the gas output from the air inlet pipe 20 are mixed in the water-gas mixing pipe 30 to form a high-pressure water-gas mixture, and then input into the RO filter pipe 40, the high-pressure water-gas mixture can be used to flush the RO membrane filter element 41 in the RO filter pipe 40. In another specific embodiment, if the water output from the water inlet pipe 10 and the gas output from the air inlet pipe 20 are mixed in the water-gas mixing pipe 30 to form a high-pressure water-gas mixture, and the high-pressure water-gas mixture is bubbled after pressure release to form microbubble water, and then input into the RO filter pipe 40, the microbubble water can be used to flush the RO membrane filter element 41 in the RO filter pipe 40. In another specific embodiment, if only the gas output from the air inlet pipe 20 is input into the RO filter pipe 40 after passing through the water-gas mixing pipe 30, the high-pressure pure gas can be used to flush the RO membrane filter element 41 in the RO filter pipe 40. In this way, the microbubble water purifier can achieve multiple flushing of the RO membrane filter element 41 to improve the filtering capacity of the RO membrane filter element 41 after long-term use, increase the service life of the RO membrane filter element 41, reduce the replacement frequency of the RO membrane filter element 41, and effectively improve the water quality of the purified water output by the RO membrane filter element 41.

[0046] According to the technical solution in the embodiment of the utility model, the micro-bubble water purifier includes a water inlet pipe, an air inlet pipe, a water-gas mixing pipe and an RO filter pipe; the RO filter pipe includes an RO membrane filter element; the input end of the water-gas mixing pipe is respectively connected to the output end of the water inlet pipe and the output end of the air inlet pipe; the output end of the water-gas mixing pipe is connected to the input end of the RO filter pipe. The micro-bubble water purifier connects the output end of the water-gas mixing pipe with the input end of the RO filter pipe, so that the output of the water-gas mixing pipe can flush the RO membrane filter element in the RO filter pipe. If the water output from the water inlet pipe and the gas output from the air inlet pipe are mixed in the water-gas mixing pipe to form a high-pressure water-gas mixture, the high-pressure water-gas mixture can be used to flush the RO membrane filter element in the RO filter pipe. If the water output from the water inlet pipe and the gas output from the air inlet pipe are mixed in the water-gas mixing pipe to form a high-pressure water-gas mixture, and the high-pressure water-gas mixture is After the pressure is released and bubbles are generated, microbubble water is formed, which can be used to flush the RO membrane filter element in the RO filter pipe. If only the gas output from the air inlet pipe is input into the RO filter pipe after passing through the water-gas mixing pipe, the high-pressure pure gas can be used to flush the RO membrane filter element in the RO filter pipe. That is, the microbubble water purifier can provide purified drinking water and microbubble water at the same time, and can also perform multiple flushing on the RO membrane filter element, which effectively improves the water quality of users' drinking water, increases the life of the RO membrane filter element and the entire water purifier, and enhances the user's experience.

[0047] Optionally, continue to refer to Figure 1 The microbubble water purifier also includes a first microbubble water pipeline 50; the first microbubble water pipeline 50 includes a first microbubble water sub-pipeline 51 and a second microbubble water sub-pipeline 52; the input end of the first microbubble water sub-pipeline 51 is connected to the output end of the water-gas mixing pipeline 30; the output end of the first microbubble water sub-pipeline 51 is respectively connected to the input end of the second microbubble water sub-pipeline 52 and the input end of the RO filter pipeline 40.

[0048] Specifically, the microbubble water purifier includes a water inlet pipe 10, an air inlet pipe 20, a water-gas mixing pipe 30, an RO filter pipe 40 and a first microbubble water pipe 50. The first microbubble water pipe 50 includes a first microbubble water sub-pipe 51 and a second microbubble water sub-pipe 52. Among them, the input end of the first microbubble water sub-pipe 51 is connected to the output end of the water-gas mixing pipe 30, that is, the high-pressure water-gas mixture in the water-gas mixing pipe 30 can be output to the first microbubble water sub-pipe 51, and in the first microbubble water sub-pipe 51, the high-pressure water-gas mixture is released by pressure and bubbles to form microbubble water. The output end of the first microbubble water sub-pipe 51 is respectively connected to the input end of the second microbubble water sub-pipe 52 and the input end of the RO filter pipe 40, that is, the microbubble water in the first microbubble water sub-pipe 51 can be output to the second microbubble water sub-pipe 52 or to the RO filter pipe 40. It is understandable that when the microbubble water in the first microbubble water sub-pipeline 51 is output to the RO filter pipe 40, the microbubble water can be used to rinse the RO membrane filter element 41 in the RO filter pipe 40. When the microbubble water in the first microbubble water sub-pipeline 51 is output to the second microbubble water sub-pipeline 52, microbubble water can be output at the output end of the second microbubble water sub-pipeline 52 to provide it to the user. And pure water / purified water can be output at the output end of the RO filter pipe 40. In this way, the microbubble water purifier can provide purified drinking water and microbubble water compatibly.

[0049] In addition, a microbubble water faucet can be connected to the output end of the second microbubble water sub-pipeline 52, and the microbubble water faucet is used to output microbubble water. A pure water faucet can be connected to the output end of the RO filter pipe 40, and the pure water faucet is used to output pure water / purified water. Alternatively, the microbubble water faucet and the pure water faucet are integrated into the same double faucet, and a water outlet pipe is provided on the double faucet. When the microbubble water faucet is turned on, the water outlet pipe is used to discharge microbubble water. When the pure water faucet is turned on, the water outlet pipe is used to discharge pure water / purified water. The embodiments of the utility model are only examples here and are not limited.

[0050] Further, continue to refer to Figure 1 The first micro-bubble water sub-pipeline 51 includes a bubble solenoid valve 53 ; one end of the bubble solenoid valve 53 is connected to the input end of the first micro-bubble water sub-pipeline 51 ; the other end of the bubble solenoid valve 53 is connected to the output end of the first micro-bubble water sub-pipeline 51 .

[0051] Specifically, the foaming solenoid valve 53 can be understood as a parallel structure of a bubbler and a solenoid valve. When the foaming solenoid valve 53 is turned off, it is equivalent to a bubbler, and the foaming solenoid valve 53 can play a role of reducing pressure and releasing, so that the high-pressure water-gas mixture is converted into micro-bubble water.

[0052] Further, continue to refer to Figure 1 The second microbubble water sub-pipeline 52 includes a microbubble water solenoid valve 54; one end of the microbubble water solenoid valve 54 is connected to the input end of the second microbubble water sub-pipeline 52. In this way, the microbubble water solenoid valve 54 can control the on-off of the second microbubble water sub-pipeline 52.

[0053] Optionally, Figure 2 Schematic diagram of another micro bubble water purifier provided by the embodiment of the utility model. Figure 2 As shown, the microbubble water purifier further includes a second microbubble water pipeline 60; the input end of the second microbubble water pipeline 60 is connected to the output end of the water-gas mixing pipeline 30 and the input end of the RO filtering pipeline 40 respectively.

[0054] Specifically, the microbubble water purifier includes a water inlet pipe 10, an air inlet pipe 20, a water-gas mixing pipe 30, an RO filter pipe 40, and a second microbubble water pipe 60. Among them, the input end of the second microbubble water pipe 60 is respectively connected to the output end of the water-gas mixing pipe 30 and the input end of the RO filter pipe 40, that is, the high-pressure water-gas mixture in the water-gas mixing pipe 30 can be output to the RO filter pipe 40 and the second microbubble water pipe 60 respectively. It can be understood that when the high-pressure water-gas mixture in the water-gas mixing pipe 30 is output to the RO filter pipe 40, the high-pressure water-gas mixture can be used to rinse the RO membrane filter element 41 in the RO filter pipe 40. When the high-pressure water-gas mixture in the water-gas mixing pipe 30 is output to the second microbubble water pipe 60, the high-pressure water-gas mixture forms microbubble water after pressure release and bubbling, and microbubble water can be output at the output end of the second microbubble water pipe 60 to provide it to users. And pure water / purified water can be output at the output end of the RO filter pipe 40. In this way, the microbubble water purifier can provide purified drinking water and microbubble water. In another embodiment, only the gas output from the air inlet pipe 20 is input into the RO filter pipe 40 after passing through the water-gas mixing pipe 30, and the high-pressure pure gas can be used to flush the RO membrane filter element 41 in the RO filter pipe 40. At this time, the output end of the second microbubble water pipe 60 will not output microbubble water, and the output end of the RO filter pipe 40 will not output pure water / purified water.

[0055] In addition, a microbubble water faucet can be connected to the output end of the second microbubble water pipeline 60, and the microbubble water faucet is used to output microbubble water. A pure water faucet can be connected to the output end of the RO filter pipeline 40, and the pure water faucet is used to output pure water / purified water. Alternatively, the microbubble water faucet and the pure water faucet are integrated into the same double faucet, and a water outlet pipe is provided on the double faucet. When the microbubble water faucet is turned on, the water outlet pipe is used to discharge microbubble water. When the pure water faucet is turned on, the water outlet pipe is used to discharge pure water / purified water. The embodiments of the utility model are only examples here and are not limited.

[0056] Further, continue to refer to Figure 2 , the second micro-bubble water pipeline 60 includes a bubbler 61; one end of the bubbler 61 is connected to the input end of the second micro-bubble water pipeline 60. Further, the second micro-bubble water pipeline 60 also includes a micro-bubble water electromagnetic valve 54; one end of the micro-bubble water electromagnetic valve 54 is connected to the input end of the second micro-bubble water pipeline 60, and the other end of the micro-bubble water electromagnetic valve 54 is connected to one end of the bubbler 61; or, one end of the micro-bubble water electromagnetic valve 54 is connected to one end of the bubbler 61, and the other end of the micro-bubble water electromagnetic valve 54 outputs micro-bubble water.

[0057] Specifically, the second micro-bubble water pipeline 60 includes a bubbler 61 and a micro-bubble water solenoid valve 54. The bubbler 61 can release the gas dissolved in the water body through the internal filter to convert the high-pressure water-gas mixture into micro-bubble water. The micro-bubble water solenoid valve 54 can control the on-off of the second micro-bubble water pipeline 60. It is understood that the micro-bubble water solenoid valve 54 can be located upstream of the bubbler 61, or the micro-bubble water solenoid valve 54 can be located downstream of the bubbler 61.

[0058] Optionally, continue to refer to Figure 1 and Figure 2 The water-gas mixing pipeline 30 includes a gas mixing tank 31 ; one end of the gas mixing tank 31 is connected to the input end of the water-gas mixing pipeline 30 ; and the other end of the gas mixing tank 31 is connected to the output end of the water-gas mixing pipeline 30 .

[0059] Specifically, the water output from the water inlet pipe 10 and the gas output from the air inlet pipe 20 can be mixed in the water-gas mixing pipe 30, and the cavity structure of the gas mixing tank 31 in the water-gas mixing pipe 30 can ensure that the water output from the water inlet pipe 10 and the gas output from the air inlet pipe 20 are fully mixed, and the gas output from the air inlet pipe 20 is dissolved in the water output from the water inlet pipe 10, so as to obtain a high-pressure water-gas mixture in the gas mixing tank 31. That is, the gas mixing tank 31 can further increase the mutual dissolution of water and gas to ensure the amount of gas dissolved in the water body, and lay a foundation for the stability of the water flow rate of the microbubble water and the judgment of the best use effect of the microbubble water.

[0060] In addition, the water-gas mixing pipeline 30 may also include a weighing unit, which can detect the weight of the mixing tank 31, and then calculate the water level inside the mixing tank 31 according to the weight of the mixing tank 31, and then feedback and adjust the water volume output by the water inlet pipeline 10 and / or the gas volume output by the air inlet pipeline 20 according to the water level inside the mixing tank 31. Exemplarily, the weighing unit can be located upstream of the mixing tank 31, and the weighing unit can be a tension sensor 32, or the weighing unit can be located downstream of the mixing tank 31, and the weighing unit can be a weighing scale ( Figure 1 and Figure 2 The tension sensor 32 and the weighing scale can both detect the weight of the mixing tank 31. The water-gas mixing pipeline 30 can also include a water level detection unit, which can be located inside the mixing tank 31. The water level detection unit can detect the height of the water level inside the mixing tank 31, and then feedback to adjust the water volume output by the water inlet pipeline 10 and / or the gas volume output by the air inlet pipeline 20. The embodiments of the utility model are only examples and are not limited here.

[0061] Optionally, continue to refer to Figure 1 and Figure 2 The water inlet pipe 10 includes a booster pump 11, a parallel solenoid valve 12 and a pressure reducing valve 13. The parallel solenoid valve 12 and the pressure reducing valve 13 form a parallel structure; one end of the booster pump 11 is connected to the input end of the water inlet pipe 10; the other end of the booster pump 11 is connected to one end of the parallel solenoid valve 12; the other end of the parallel solenoid valve 12 is connected to the output end of the water inlet pipe 10.

[0062] Specifically, tap water can be introduced into the input end of the water inlet pipe 10, and the device in the water inlet pipe 10 can pre-treat the tap water, so that pre-filtered water can be output at the output end of the water inlet pipe 10. The water inlet pipe 10 includes a booster pump 11, a parallel solenoid valve 12 and a pressure reducing valve 13. Among them, one end of the booster pump 11 is connected to the input end of the water inlet pipe 10, and the booster pump 11 can increase the pressure of the tap water introduced. The other end of the booster pump 11 is connected to one end of the parallel solenoid valve 12, and the other end of the parallel solenoid valve 12 is connected to the output end of the water inlet pipe 10. When the parallel solenoid valve 12 is turned on, the tap water introduced can be output to the water-gas mixing pipe 30 after passing through the booster pump 11 and the parallel solenoid valve 12 in sequence. The parallel solenoid valve 12 and the pressure reducing valve 13 form a parallel structure, and one end of the booster pump 11 is also connected to one end of the pressure reducing valve 13, and the other end of the pressure reducing valve 13 is also connected to the output end of the water inlet pipe 10. And the water pressure at the input end of the pressure reducing valve 13 is higher than the water pressure at the output end of the pressure reducing valve 13, that is, the pressure reducing valve 13 can effectively reduce the water pressure. Therefore, when the parallel solenoid valve 12 is turned on, the water body will be depressurized at the pressure reducing valve 13 to limit the flow of water, and the tap water introduced will flow through the parallel solenoid valve 12. When the parallel solenoid valve 12 is turned off, the tap water introduced will flow through the pressure reducing valve 13. In addition, the pressure reducing valve 13 can effectively reduce the water pressure and reduce the water speed. While the air intake pipe 20 replenishes air to the water-gas mixing pipe 30, the water intake pipe 10 replenishes water to the water-gas mixing pipe 30 through the pressure reducing valve 13, which can avoid the problem that the water and air in the water-gas mixing pipe 30 cannot be dissolved or fully mixed due to excessive water pressure and too fast water flow, and the problem that the pressure of the micro-bubble water / purified water finally output by the micro-bubble water purifier is unstable and the flow rate increases and decreases suddenly.

[0063] In addition, the water inlet pipe 10 may also include a pre-treatment filter element 14, which is located between the input end of the water inlet pipe 10 and the booster pump 11. That is, the tap water is pre-filtered and purified by the pre-treatment filter element 14 before entering the booster pump 11, which can filter and intercept impurities with larger particles in the tap water, thereby reducing the impurity content of the raw water flowing into the booster pump 11, and correspondingly reducing the probability of impurities in the tap water blocking the booster pump 11, the RO membrane filter element 41 and the post-treatment filter element 45, thereby ensuring the normal use of the water purifier. In addition, the setting of the pre-treatment filter element 14 can greatly reduce the filtration load of the RO membrane filter element 41, thereby extending the service life of the water purifier. And the use of the booster pump 11 effectively increases the pressure of the pre-filtered water, the water inlet effect is better, and the water outlet flow rate is basically not affected by factors such as the water inlet pressure and the blockage of the pre-treatment filter element 14.

[0064] Optionally, continue to refer to Figure 1 and Figure 2 The air intake pipe 20 includes an air pump 21 ; one end of the air pump 21 is connected to the output end of the air intake pipe 20 .

[0065] Specifically, the air pump 21 can play the role of pumping air into the water-gas mixing pipeline 30. In addition, the air intake pipeline 20 can also include a one-way valve 22, which is located between the air pump 21 and the output end of the air intake pipeline 20, and the conduction direction of the one-way valve 22 is from the air pump 21 to the output end of the air intake pipeline 20. The one-way valve 22 can play the role of one-way pumping air into the water-gas mixing pipeline 30. In this way, the water output from the water intake pipeline 10 can be effectively prevented from flowing back into the air intake pipeline 20, thereby avoiding interference with the gas generation / transmission process of the air pump 21.

[0066] In a specific embodiment, the water inlet pipe 10 includes a booster pump 11, a parallel electromagnetic valve 12 and a pressure reducing valve 13; the air inlet pipe 20 includes an air pump 21. The parallel electromagnetic valve 12 and the pressure reducing valve 13 form a parallel structure. And the parallel electromagnetic valve 12 is located downstream of the booster pump 11. The output end of the air inlet pipe 20 is also located downstream of the booster pump 11. In this way, compared with the output end of the air inlet pipe 20 being connected to the input end of the booster pump 11, the output end of the air inlet pipe 20 is connected to the output end of the booster pump 11 through the parallel electromagnetic valve 12, which can effectively solve the problems of unstable pressure at the input end of the booster pump 11, difficult control of the intake flow, easy jetting of the water outlet when the intake flow is large, and low bubble content concentration of the generated micro bubble water when the intake flow is small. In addition, the air output from the air inlet pipe 20 directly enters the booster pump 11, and the booster pump 11 will have air blockage and other hazards that affect the boosting performance of the booster pump 11 and the water outlet flow of the generated micro bubble water.
