Detailed Description
the technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
example one
Referring to fig. 1, in the present embodiment, a reverse osmosis water purifier is provided. The reverse osmosis water purifier comprises a reverse osmosis filter 8 and two booster pumps 7 connected in parallel, wherein the two booster pumps 7 are positioned at the upstream of the reverse osmosis filter 8 and are communicated with the reverse osmosis filter 8. On one hand, two booster pumps 7 which are connected in parallel and have relatively low relative flow and low power are used for replacing one booster pump with high flow and high power, and the effect of increasing the flow can be effectively achieved; on the other hand, the noise of the two parallel relatively low flow and power booster pumps 7 is smaller than that of one high flow, high power booster pump.
in the present embodiment, the two booster pumps 7 have the same specification parameters. In the prior art, a large-flow 600G booster pump is mostly adopted, but two 300G booster pumps 7 can be adopted in the embodiment, and the two 300G booster pumps 7 have larger flow rate and better effect in increasing the flow rate than the one 600G booster pump. The noise of the two 300G booster pumps 7 is reduced by about 5% compared with the 600G booster pumps 7. Of course, the present embodiment is not limited to this, and two booster pumps 7 may be selected according to actual conditions.
Further, in the present embodiment, the reverse osmosis water purifier further includes an electromagnetic switch valve 12, and the electromagnetic switch valve 12 selectively enables only one of the two booster pumps 7 to communicate with the reverse osmosis filter 8 or both of the two booster pumps 7 to communicate with the reverse osmosis filter 8, that is, through the setting of the electromagnetic switch valve 12 and the operation of the electromagnetic switch valve 12, only one of the two booster pumps 7 may communicate with the reverse osmosis filter 8, or both of the two booster pumps 7 may communicate with the reverse osmosis filter 8. Thus, there are two modes of operation, one being low pressure (when only one booster pump 7 is in communication with the reverse osmosis filter 8) and the other being high pressure (when both booster pumps 7 are in communication with the reverse osmosis filter 8). When the low-pressure working mode and the high-pressure working mode are alternately performed by controlling the action of the electromagnetic switch valve 12, the water flow has a circular washing effect of washing the reverse osmosis filter element of the reverse osmosis filter 8 with a washing pressure of small-large-small. On one hand, the washing is positive washing, so that the problems of complex water path, serious consumption of a reverse osmosis filter element and the like caused by a back washing mode in the prior art can be avoided; on the other hand, the flushing mode of the flushing pressure alternating change can fully flush the reverse osmosis filter element and increase the flushing force to the reverse osmosis filter element.
More specifically, in the present embodiment, the electromagnetic switch valve 12 is provided only between one of the booster pumps 7 and the reverse osmosis filter 8, and the on/off of the booster pump 7 and the reverse osmosis filter 8 is controlled by the opening/closing of the electromagnetic switch valve 12, that is, the electromagnetic switch valve 12 is provided on a branch of one of the booster pumps 7. And, the electromagnetic switch valve 12 is controlled by a control unit (not shown in the figure) to make only one booster pump 7 and two booster pumps 7 alternately communicate with the reverse osmosis filter 8, i.e., to alternately perform the low pressure operation mode and the high pressure operation mode. For example, only one booster pump 7 is in communication with the reverse osmosis filter 8 for a duration of 5s, and both booster pumps 7 are in communication with the reverse osmosis filter 8 for a duration of 5s at the same time, that is, the on-off period of the electromagnetic opening/closing valve 12 is 5 s. Preferably, the control unit is in communication connection with the electromagnetic switch valve 12, and the electromagnetic switch valve 12 is an electromagnetic valve.
further, the reverse osmosis water purifier of this embodiment still includes water inlet tee bend and bipartition ball valve 1, the filter bank that communicates with it and the pipeline that communicates both. The filter group is located at the upstream of the two booster pumps 7, and the outlet of the filter group is respectively communicated with the inlets of the two booster pumps 7 through a first T-shaped tee 16.
specifically, the filter group comprises a pre-carbon filter 2, a 5umPP filter 5 and a 1umPP filter 6 which are communicated with each other in the upstream-downstream direction (i.e. in the water flow direction during water production), and the outlet of the 1umPP filter 6 is the outlet of the filter group. Leading activated carbon filter 2 passes through pipeline and three-way and bipartition ball valve 1 intercommunication of intaking, and 5umPP filter 5 passes through pipeline and leading activated carbon filter 2 intercommunication, and 1umPP filter 6 passes through pipeline and 5umPP filter 5 intercommunication, and first T type tee bend 16 passes through pipeline and 1umPP filter 6 intercommunication. Wherein, a low-pressure switch 3 and a water inlet electromagnetic valve 4 are arranged on a pipeline between the front activated carbon filter 2 and the 5umPP filter 5. Of course, the number, type and arrangement sequence of the filters in the filter group are not limited to this, and may be set according to specific conditions.
Further, the reverse osmosis water purifier of this embodiment further includes a second T-shaped tee 17, a rear activated carbon filter 15, a faucet 14, and a water storage bucket 13. The first interface of the second T-shaped tee joint 17 is communicated with the pure water outlet of the reverse osmosis filter 8 through a pipeline, the rear activated carbon filter 15 is communicated with the second interface of the second T-shaped tee joint 17 through a pipeline, the water faucet 14 is connected in series with the downstream of the rear activated carbon filter 15 and communicated with the rear activated carbon filter 15 through a pipeline, the water storage barrel 13 is communicated with the third interface of the second T-shaped tee joint 17 through a pipeline, and the pipeline between the first interface of the second T-shaped tee joint 17 and the pure water outlet of the reverse osmosis filter 8 is also connected with the high-pressure switch 11.
In addition, the reverse osmosis water purifier of this embodiment further includes a first wastewater branch 18, a wastewater ratio electromagnetic valve 9, a second wastewater branch 19, and a flushing electromagnetic valve 10.

The two waste water branches are finally converged to a main path.
In conclusion, when the reverse osmosis water purifier of the embodiment is in a water production state, the low-pressure switch 3, the water inlet electromagnetic valve 4, the high-pressure switch 11, the wastewater ratio electromagnetic valve 9 and the electromagnetic switch valve 12 are opened, the flushing electromagnetic valve 10 is closed, water enters from the water inlet three-way valve and the two-branch ball valve 1 and is filtered by the pre-activated carbon filter 2, the 5umPP filter 5 and the 1umPP filter 6 in sequence, then enters a reverse osmosis filter 8 for filtration after being pressurized by two booster pumps 7, then enters a water storage bucket 13 for collection from a pure water outlet through a second T-shaped tee 17, when the water tap 14 is opened, the water in the water storage barrel 13 flows out of the water tap 14 after the taste of the water is improved by the post-positioned activated carbon filter 15, of course, when the faucet 14 is opened, the water from the pure water outlet also flows out from the faucet 14 after the taste of the water is improved by the second T-shaped tee 17 through the post-activated carbon filter 15. The wastewater flows from the wastewater outlet of the reverse osmosis filter 8 through the first wastewater branch 18.
