The utility model relates to a water purification field especially relates to a pure water bubble membrane system based on pure water case.
Background
The reverse osmosis water purifier is the most common scheme of the existing water purifying equipment. However, the existing reverse osmosis water purifier has the following disadvantages: when the reverse osmosis water purifier stops and stands still, the reverse osmosis membrane is in thick water soaking for a long time, so that water on the raw water side of the reverse osmosis membrane permeates into water on the pure water side, the TDS value of the water on the pure water side is close to that of the raw water side of the reverse osmosis membrane, and after the reverse osmosis water purifier restarts to produce water, the initially produced pure water TDS value (within 2 minutes) greatly exceeds a standard value; secondly, because the reverse osmosis membrane is soaked in the concentrated water for a long time, the service life of the reverse osmosis membrane is greatly shortened due to the fact that the surface of the membrane is easy to be structurally formed.
At present, there is reverse osmosis water purification machine to have increased pure bubble membrane function, replaces the high concentration water in the reverse osmosis filter core through the pure water, makes reverse osmosis water purification machine under the machine-halt state, and the water TDS value of its reverse osmosis membrane raw water side is close with the water TDS value of reverse osmosis membrane pure water side, avoids reverse osmosis membrane to be in the machine-halt state at reverse osmosis water purification machine and the osmosis phenomenon appears. However, when water in the raw water side of the reverse osmosis filter element is replaced, the water originally stored in the raw water side of the reverse osmosis filter element is discharged out of the water purifier, which wastes water resources.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pure water bubble membrane system based on pure water case, through the application of pure water case, make water purification system when the water of the former water side of replacement reverse osmosis filter core, can save the water of originally saving in the former water side of reverse osmosis filter core in water purification system, reuse when water purification system prepares the pure water next time.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a pure water bubble membrane system based on a pure water tank comprises a filter element group, wherein the filter element group is communicated with a water inlet for raw water to flow in, a water outlet for concentrated water to discharge and a drinking water outlet for pure water to discharge;
the pure water tank comprises a tank body, wherein an elastically deformable built-in tank is arranged in the tank body, and a water flow channel is arranged between the built-in tank and the tank body; one end of the water flow channel is communicated with the booster pump, the other end of the water flow channel is communicated with the water inlet and the water outlet respectively, a first check valve which enables water flow to flow from the water inlet to the water flow channel is arranged between the water inlet and the water flow channel, and a pressure release valve which enables water flow to flow from the water flow channel to the water outlet is arranged between the water flow channel and the water outlet;
the water flows along the water inlet, the first check valve, the water flow channel, the booster pump, the raw water inlet, the reverse osmosis filter element, the pure water outlet and the drinking water port to form a pure water making path;
the water flow circulates along the reverse osmosis filter element, the concentrated water outlet, the booster pump and the water flow channel to form a water return path in the filter element;
the water flows through the reverse osmosis filter element along the built-in tank and the raw water inlet to form a pure water bubble film path;
the water flows through the built-in tank along the reverse osmosis filter element and the pure water outlet to form a pure water reflux path;
the water flow flows along the water flow channel, the pressure release valve and the water outlet to form a concentrated water pressure release path.
The principle of the utility model is as follows:
before the pure water bubble membrane system realizes the pure water bubble membrane, pure water needs to be prepared firstly. When preparing pure water, tap water or other raw water flows into the water flow channel through the water inlet and flows to the reverse osmosis filter element through the water flow channel. After being filtered by the reverse osmosis filter element, most of the purified water flows out through the drinking water port for users to use, and a small part of the purified water is shunted to the built-in tank for storage through the purified water backflow path. The concentrated water produced in the process of preparing pure water is discharged through the water outlet. After the user stops getting water or the built-in tank stores enough pure water, the pure water bubble membrane system can stop preparing pure water.
After the user stops getting water, the pure water bubble membrane system can be switched to a pure water bubble membrane state. At this time, the pure water bubble film system does not have external water inflow, and does not discharge water to the outside. The booster pump operates to make the water staying at the raw water side in the reverse osmosis filter element flow along the element water return path, and the water staying in the reverse osmosis filter element is pumped out from the concentrated water outlet and flows into the water flow channel of the pure water tank through the booster pump. Because the restriction of first check valve, the water that gets into the rivers inslot can only stay in rivers passageway, extrude built-in jar and make built-in jar elastic deformation, the volume that makes built-in jar changes, make this built-in jar produce deformation and the volume dwindles, the pure water of saving in built-in jar is extruded to the volume change through built-in jar, flow through built-in jar and raw water inlet switch-on, the pure water can flow to the former water side of reverse osmosis filter core through raw water inlet, occupy because of originally the water that stays the former water side of reverse osmosis filter core is taken out the vacancy that brings. And because built-in jar pressurized deformation, the volume of built-in jar is dwindled, set up the corresponding increase of volume of the rivers passageway between box and built-in jar, can hold more water, guarantee from this that the water that stops in the former water side of reverse osmosis filter core can all be taken out by the booster pump, make originally the pure water of saving in built-in jar occupy the whole spaces of the former water side of reverse osmosis filter core, thereby make reverse osmosis water purifier under the standby state, reverse osmosis membrane's both sides are the pure water and soak, the water TDS value of the both sides of reverse osmosis membrane is close, even the former water side and the pure water side of reverse osmosis filter core take place the osmosis phenomenon under pure water bubble membrane system standby state, the water TDS value that also can not lead to the pure water side rises by a wide margin, thereby avoid the problem that the first water TDS value of.
At above-mentioned pure water bubble membrane in-process, the pure water of saving in built-in jar is by whole back of extruding, and the booster pump continues to extract the water that stops in the former water side of reverse osmosis filter core, can lead to the pressure in the rivers passageway to constantly rise, and at this moment, the rivers of being pumped in the rivers passageway can flow along dense water pressure release route, flow through rivers passageway, one-way relief valve, outlet, and this pure water bubble membrane system of discharge avoids the inside water pressure of this pure water bubble membrane system to exceed safe range.
In the pure water bubble membrane process, the water inlet and outlet of the pure water bubble membrane system are closed, for example, a water inlet through which raw water flows into the pure water bubble membrane system, a drinking water inlet through which pure water flows out of the pure water bubble membrane system, a water outlet through which concentrated water flows out of the pure water bubble membrane system, and the like, so that the pure water bubble membrane system enters an internal circulation mode. The external water source can not flow into the pure water bubble film system, and the pure water bubble film system can not discharge water to the outside. After the pure water bubble membrane state is finished, the water pumped out from the raw water side of the reverse osmosis filter element stays in the water flow channel. When the water purification system produces water for the next time, the water staying in the water flow channel is completely reused and is filtered by the reverse osmosis filter element to obtain pure water and concentrated water.
Under the pure water bubble membrane state, the flow of the water that flows in water purification system is not many, and water purification system accessible time control or TDS value detect the mode control such as originally save the outflow of the pure water in built-in jar, guarantee originally to save the outflow of the pure water in built-in jar can satisfy in the reverse osmosis filter core that the water TDS value of raw water side reduces to the setting value can.
Besides the preparation of pure water and the pure water bubble membrane, the pure water bubble membrane system can also realize the raw water flushing so as to flush the membrane layer according to the requirements of users. The water flows along the water inlet, the water flow channel, the booster pump, the raw water inlet, the reverse osmosis filter element, the concentrated water outlet and the water outlet to form a raw water flushing path.
After the user stops getting water, the pure water bubble membrane system can enter a raw water flushing state. At this time, the drinking water port stops discharging water. Running water or other raw water flows along the raw water flushing path, flows to the raw water inlet of the reverse osmosis filter element through the water flow channel, enters the raw water side of the reverse osmosis filter element, and extrudes the water staying at the raw water side of the reverse osmosis filter element to the water outlet for discharge. In this process, the pure water bubble membrane path is made negative pressure by the operation of the booster pump, and the pure water stored in the built-in tank does not flow into the reverse osmosis filter element along the pure water bubble membrane path.
This filtration filter element group of pure water bubble membrane system can also include leading filter element group, and this leading filter element group sets up the upper reaches at the pure water case and communicates with rivers passageway, and rivers flow into rivers in the flow path along leading filter element group, second check valve. The pre-filter group is as the primary filter group of this pure water bubble membrane system, and its material can adopt current conventional material, like PP cotton etc. mainly filters the effect of the impurity in the former aquatic of step at first. Further, this pure water bubble membrane system's filtration filter core group can also include rearmounted filter core group, and this rearmounted filter core group sets up in reverse osmosis filter core's low reaches and communicates with the pure water outlet, and rivers flow to the drinking water mouth along pure water outlet, rearmounted filter core group. The post-filter group is used as a final filter group of the pure water bubble membrane system and is mainly used for improving the taste of pure water filtered by the reverse osmosis filter element. The material of the post-filter group can adopt the existing conventional design, such as a carbon rod and the like.
The pure water bubble membrane system can be switched between pure water preparation, raw water flushing and a pure water bubble membrane based on opening and closing control of a valve, specifically, a first control valve can be arranged between an inlet of the water flow channel and a booster pump, a second control valve can be arranged between an outlet of the concentrated water and an inlet of the booster pump, a third control valve can be arranged between an outlet of the booster pump and the raw water inlet, a fifth control valve can be arranged between the concentrated water outlet and a water outlet, and a fourth control valve can be arranged between the outlet of the booster pump and the water flow channel.

Based on the water flow path, the pure water bubble membrane system has three working states, namely a pure water making state, a raw water flushing state and a pure water bubble membrane state.
When the water purification system is in a pure water production state, the water inlet 1 is opened, the drinking water port 8 is opened, the first control valve 16 is opened, the second control valve 17 is closed, the third control valve 18 is opened, the fifth control valve 22 is opened, and the fourth control valve 19 is closed, at this time, tap water flows into the pre-filter group 2 from the water inlet 1 through the pressure reducing valve 26, flows into the water flow channel 14 through the first check valve 15, then flows to the pressurization inlet 24 of the pressurization pump 4 through the first control valve 16, and flows to the third control valve 18 from the pressurization outlet 25. After passing through the third control valve 18, the water flows into the reverse osmosis cartridge 5 through the raw water inlet 9. After being filtered by the reverse osmosis filter element 5, most of the purified water flows to the post-filter unit 6 through the pure water outlet 11 and the fifth check valve 23, flows out from the drinking water port 8 after being filtered by the post-filter unit 6 for being used by a user, and a small part of the purified water is shunted through the pure water backflow path, flows to the built-in tank 13 from the pure water outlet 11 and is stored in the built-in tank 13. The concentrated water generated during the filtering process flows to the fifth control valve 22 through the concentrated water outlet 10 and is then discharged from the drain port 7.
When the water purification system is in a raw water flushing state, the water inlet 1 is opened, the drinking water port 8 is closed, the first control valve 16 is opened, the second control valve 17 is closed, the third control valve 18 is opened, the fifth control valve 22 is opened, and the fourth control valve 19 is closed, at this time, tap water flows into the pre-filter group 2 from the water inlet 1 through the pressure reducing valve 26, flows into the water flow channel 14 through the first check valve 15, then flows to the pressurizing inlet 24 of the pressurizing pump 4 through the first control valve 16, and flows to the third control valve 18 from the pressurizing outlet 25. After passing through the third control valve 18, the water flows into the reverse osmosis cartridge through the raw water inlet 9. Since the drinking water port 8 is closed, the reverse osmosis filter element 5 does not filter pure water, and tap water flowing into the reverse osmosis filter element 5 washes the raw water side of the reverse osmosis membrane, flows to the fifth control valve 22 through the concentrated water outlet 10, and is then discharged from the water outlet 7. This process of washing's effect lies in the water that the discharge stayed in 5 former water sides of reverse osmosis filter core, clean reverse osmosis membrane and tentatively reduce the water TDS value of 5 former water sides of reverse osmosis filter core.
When the water purification system is in a pure water bubble membrane state, the water inlet 1 is closed, the drinking water port 8 is closed, the first control valve 16 is closed, the second control valve 17 is opened, the third control valve 18 is closed, the fifth control valve 22 is closed, the fourth control valve 19 is opened, at this time, the booster pump 4 operates to enable water staying at the raw water side in the reverse osmosis filter element 5 to flow along the in-core water return flow path, water staying in the reverse osmosis filter element 5 is pumped out from the concentrated water outlet 10, flows to the booster pump through the second control valve 17, then flows to the fourth control valve 19 through the booster outlet 25 and finally flows into the water flow channel 14 of the pure water tank 3, due to the action of the first check valve 15, water flowing into the water flow channel 14 can only stay in the water flow channel 14 to press the internal tank 13, the internal tank 13 is pressed and deformed by the water in the water flow channel 14, and pure water stored in the internal tank 13 is squeezed out from the internal tank 13, flows to the raw water inlet 9 through the second check valve 20 and then flows into the raw water side of the reverse osmosis filter element 5. The water flowing to the raw water side of the reverse osmosis filter element 5 flows out from the concentrated water outlet and returns to the water flow channel 14 of the pure water tank 3 under the pressurization effect of the booster pump 4.
In the above-mentioned in-process, the pure water of originally saving in built-in jar 13 can replace the water that stays in the former water side of reverse osmosis filter core 5 gradually, makes the water TDS value of the former water side reduce in the reverse osmosis filter core 5, makes the water TDS value of the former water side of reverse osmosis filter core 5 and the water TDS value of the pure water side of reverse osmosis filter core 5 tend to be close, has avoided water purification system under the standby state, and the former water side of reverse osmosis filter core 5 and pure water side appear the osmosis phenomenon and lead to the water TDS value of pure water side to rise by a wide margin. When the water purification system is switched from the pure water bubble membrane state to the pure water making state, most of water in the core water return path, the pure water bubble membrane path and the built-in tank 13 enters the reverse osmosis filter element 5 again through the raw water inlet 9 for filtration and reuse.
In the above process, after the pure water stored in the built-in tank 13 is completely squeezed out, the booster pump 4 continues to pump the water staying in the raw water side of the reverse osmosis filter element 5, which causes the pressure in the water flow channel 14 to continuously rise, at this time, the water flow pumped into the water flow channel 14 immediately flows along the concentrated water pressure relief path, flows through the water flow channel 14, the one-way pressure relief valve 28 and the water outlet 7, and is discharged out of the pure water bubble membrane system.
The preferred embodiment of the present invention is only listed in the present specification, and all the technical changes equivalent to those made under the working principle and thought of the present invention are considered as the protection scope of the present invention.
