A reverse osmosis filtration water purifier without plug-in according to the present invention will be described with reference to fig. 1 to 4.
In one embodiment, a reverse osmosis filtration water purifier without plug-in comprises a water tank 310, a water bag 320 and a reverse osmosis filtration module; the water bag 320 is disposed inside the water tank 310 and forms a first interlayer for storing water with the water tank 310; the inlet end of the reverse osmosis filtration module is connected with the tap water inlet 110, the first outlet end is connected to the inside of the water bag 320, and the second outlet end is connected with the wastewater outlet 130; the tap water inlet 110 is also communicated with the first interlayer; the first interlayer is communicated with the outside through a mechanical control valve, and the on-off control of the control valve realizes the change of the pressure in the first interlayer; when tap water flows into the first interlayer under the influence of the pressure of the water body of the tap water and flows into the water bag 320 after being filtered into purified water by the reverse osmosis filter module, the internal pressure of the water bag 320 is larger than the internal pressure of the first interlayer, and the water bag 320 expands until the inside is filled with the purified water; when the purified water in the water bladder 320 flows out along the purified water outlet 120, the internal pressure of the water bladder 320 is smaller than the internal pressure of the first interlayer, and the water bladder 320 contracts until the purified water in the water bladder is completely discharged.
In the reverse osmosis water purifier without power-on, when water is filtered, tap water enters the reverse osmosis filtration module through the tap water inlet 110, and the purified water outlet 120 is in a closed state, so that purified water obtained after filtration can only flow into the water bag 320 along the first outlet end, and in the process, the pressure inside the water bag 320 is greater than the pressure inside the first interlayer because the first interlayer is communicated with the outside, and the water inside the water bag 320 is filled until the pressure is full under the pressure difference. When the purified water in the water bag 320 flows out along the purified water outlet 120, the pressure inside the water bag 320 is released, so that the internal pressure of the water bag 320 is smaller than the internal pressure of the first interlayer, the first interlayer is filled with water and extrudes the water bag 320, and finally the purified water inside the water bag 320 is discharged along the purified water outlet 120.
In the reverse osmosis filtration water purifier without power-on, the whole water tank 310 can be filled with purified water, so that the space is saved to the greatest extent in a limited volume. And the water tank 310 and the water purifier shell in the embodiment can be integrally designed, and the whole water purifier shell is formed by welding, so that the waterway is simple and clear, and the production and the maintenance are more convenient.
In one embodiment, the tap water inlet 110, the clean water outlet 120 and the waste water outlet 130 are integrated into a water inlet and outlet control valve, the water inlet and outlet control valve further comprising a waste water outlet 130, the waste water outlet 130 being in communication with the first interlayer; during the filling process of the water bladder 320, tap water in the first interlayer is squeezed out along the waste water outlet 130.
Specifically, the size of the internal space of the first interlayer is changed no matter the water bag 320 is expanded or contracted, so that the wastewater outlet 130 is arranged and communicated with the interior of the first interlayer, when water is introduced into the water bag 320 to expand, air in the interior of the first interlayer is extruded and flows out to the outside along the wastewater outlet 130, and meanwhile, if the water bag 320 is expanded, tap water is provided in the interior of the first interlayer, and then the tap water flows out along the wastewater outlet 130. In addition, the tap water inlet 110, the purified water outlet 120 and the waste water outlet 130 of the reverse osmosis filtration water purifier without power-on are all arranged at the top of the water tank 310 and are integrated into a water inlet and outlet control valve, so that the overall structure is further simplified.
In one embodiment, a first filtration stage is provided between the inlet end and the first outlet end of the reverse osmosis filtration module, and a second filtration stage is provided between the first outlet end of the reverse osmosis filtration module and the purified water outlet 120; the first filtering stage is for filtering tap water introduced through the tap water inlet 110, and the second filtering stage is for filtering purified water flowing back in the water bladder 320.
Specifically, tap water filtered in the first stage enters the water bag 320 along the first outlet end, and water in the water bag 320 flows out along the original water inlet path when water is discharged, so that impurities in the water possibly exist due to the fact that paths overlap are avoided, and water flowing out of the water bag 320 also needs to pass through the second filtering stage, so that water quality is guaranteed to be clean.
In one embodiment, the first filtering stage comprises a primary polypropylene filtering component 210, a secondary post-activated carbon filtering component 220 and a tertiary reverse osmosis membrane filtering component 240 which are sequentially connected, wherein the primary polypropylene filtering component 210 is also connected with a tap water inlet 110; the second filtering stage comprises a four-stage post-activated carbon filter assembly 250, which is respectively connected with the three-stage reverse osmosis membrane filter assembly 240 and the purified water outlet 120.
Specifically, a primary polypropylene (pp) filter assembly is used to remove large particle impurities, silt, ova, rust, and the like. The secondary post-activated carbon filter assembly 220 is used for removing residual chlorine, high molecular organic matters, colloid substances and the like in water.
The reverse osmosis membrane has very small pore size, and only about 1/10000 of the water molecules can be used for filtering out substances such as microorganisms, heavy metals and organic matters in water, so that the reverse osmosis membrane on the market can intercept substances larger than 0.0001 micron and remove the substances such as microorganisms, heavy metals and organic matters in water. The working characteristics of the reverse osmosis water purifier determine that the existing reverse osmosis water purifier mostly adopts a mode of an electric-plugging pressurizing pump to filter a reverse osmosis filter membrane under a certain pressure, and the reverse osmosis water purifier without electric plugging in the embodiment provides osmotic pressure by utilizing the water pressure of tap water and matching with the opening and closing of a plurality of water inlets and outlets on a water inlet control valve, so that the reverse osmosis water purifier with the reverse osmosis filtering function is realized. Wherein, the wastewater outlet 130 is also connected with a three-stage reverse osmosis membrane filtering component 240 for discharging the filtered wastewater.
In one embodiment, a stop valve 230 is connected between the primary polypropylene filter assembly 210 and the secondary post-activated carbon filter assembly 220, the stop valve 230 being used to allow tap water to flow from the primary polypropylene filter assembly 210 to the secondary post-activated carbon filter assembly 220; a four-way valve 260 is connected between the three-stage reverse osmosis membrane filter assembly 240 and the four-stage rear active carbon filter assembly 250, and the four-way valve 260 is respectively connected with the stop valve 230, the three-stage reverse osmosis membrane filter assembly 240, the water bag 320 and the four-stage rear active carbon filter assembly 250; when the purified water in the water bladder 320 is filled and is flushed to the shut-off valve 230 through the four-way valve 260, the shut-off valve 230 is closed so that tap water cannot enter the secondary post-activated carbon filter assembly 220.
Specifically, tap water can only flow from the primary polypropylene filter unit 210 to the secondary rear activated carbon filter unit 220, when the inside of the water bag 320 is filled with purified water, and the purified water level rises and is flushed to the stop valve 230 through the four-way valve 260, the stop valve 230 is closed, the primary polypropylene filter unit 210 and the secondary rear activated carbon filter unit 220 are interrupted, the whole system is interrupted, and the preparation of purified water is stopped.
In one embodiment, the four filter assemblies are identical in construction, the filter assemblies comprising a filter element housing 290, a ring cartridge 2100, and a filter element upper cover; the annular filter cartridge 2100 is disposed within the filter element housing 290 with a second interlayer therebetween; the filter upper cover comprises a filter end water inlet 270 and a filter end water outlet 280, tap water enters the second interlayer through the filter end water inlet 270, and tap water in the second interlayer flows out of the filter end water outlet 280 after being filtered by the annular filter element 2100.
Specifically, the filter member housing 290 and the filter member upper cover are detachable, so that the filter member 2100 can be cleaned when the impurities filtered out from the surface of the filter member 2100 are too much, so as to avoid affecting the filtering effect of the filter member 2100.
In one embodiment, a top limiting piece 2110 and a bottom limiting piece 2120 are arranged in the filter piece housing 290, the top limiting piece 2110 is clamped on the inner ring and the outer ring at the top of the annular filter element 2100, a through hole 2111 is formed in the middle of the top limiting piece 2110 in a penetrating way, and the water outlet 280 at the filtering end is communicated with the interior of the annular filter element 2100 through the through hole 2111; the bottom stop 2120 is clamped to the inner and outer races of the bottom of the annular cartridge 2100.
Specifically, top limiter 2110 and bottom limiter 2120 all are annular structure setting, and can stablely block into filter element housing 290 interior top and interior bottom, because top limiter 2110 and bottom limiter 2120 all can carry out the joint to the inner circle and the outer lane of annular filter core 2100, therefore the stable of annular filter core 2100 structure and position can be guaranteed to the combination of top limiter 2110 and bottom limiter 2120, avoids producing deformation or displacement at the in-process that receives the running water to wash out.
In one embodiment, the filter housing 290 is fixed to the top stop 2110 by a spacer 2130, the inner ring of the spacer 2130 engages the top stop 2110 at intervals, and tap water entering through the filter inlet 270 enters the second interlayer through the non-engagement between the spacer 2130 and the top stop 2110.
Specifically, the outer ring of the positioning sleeve 2130 is completely attached to the opening of the filter element, the inner ring main body of the positioning sleeve 2130 is in an annular structure and is used for being attached to the top limiting element 2110, in addition, through grooves are circumferentially arranged on the annular structure of the inner ring of the positioning sleeve 2130 at intervals, the opening of the through grooves is attached to the top limiting element 2110, the top end and the bottom end of the through grooves are communicated, and the water inlet 270 of the filter end and the second interlayer are respectively connected.
In one embodiment, the opening of the water tank 310 is provided with a support tube 330, the bottom of the support tube 330 is sealed, and the surface of the support tube 330 located at the inner portion of the water bag 320 is provided with a water permeable hole 331, and the purified water flowing into the water bag 320 flows into the water bag 320 through the water permeable hole 331. The supporting tube 330 is used for supporting the water bag 320, so as to avoid damage caused by overlarge deformation when the water bag 320 contracts.
It should be noted that, when the water filtering and the water using are used synchronously, the water outlet rate of the purified water is far greater than the preparation rate of the purified water, which is specifically shown that the purified water in the water bag 320 is emptied and completely released immediately after the purified water outlet 120 is opened, and at this time, the water bag 320 is almost free of purified water.
In the process of preparing the purified water, the water bag 320 is gradually filled from a compressed state to a natural state (for example, the state of about 5L capacity is reached in practical equipment), in this process, tap water is filtered through filter elements of all stages after entering through adjustment of a water inlet and outlet control valve, and finally the purified water obtained through filtration is injected into the water bag 320. The tap water inlet 110 and the waste water outlet 130 outside the water tank 310 can be directly connected and discharged to the outside, so that the first interlayer is in a non-pressure state, and the water bag 320 can be inflated by water. Compared with the traditional pneumatic water storage mode, the reverse osmosis membrane rear gauge pressure of the reverse osmosis filtration water purifier without power-on in the embodiment is close to zero, the osmotic pressure is kept unchanged in the whole working process, the water yield is unchanged, and the energy and water are saved.
The whole working process and the start-stop state of the reverse osmosis filtration water purifier without power-on are dependent on the interaction of the water tank 310, the water bag 320, the water inlet and outlet control valve, the stop valve 230 and the four-way valve 260, the start-stop process is not matched with an electronic mechanism and an electronic component, the control part of the whole machine is completely realized by a mechanical control valve, and the control part is driven by water pressure, so that the reverse osmosis filtration water purifier is less and more reliable relative to an electric control fault point.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
