Summary of the invention
The technical problems to be solved in the utility model is to provide RO water-purifying machine, the utility model efficiently solves the RO membrane cartridge of traditional RO water-purifying machine in stopping Water treatment, because filter flask is directly communicated with pressure-pot, under causing RO filter core to be in pressure effect for a long time, not only can cause the water purification reflux problem in pressure-pot, and can affect RO membrane cartridge purifying water effect and work-ing life problem.
The utility model is achieved through the following technical solutions:
A kind of pressure-bearing type RO water-purifying machine, comprise water purifier body (9), water purifier body is provided with Combination filter element in (9), described Combination filter element comprises the cotton filter core (10) of PP successively, active carbon filter core (11), RO membrane cartridge (12) and post active carbon filter core (13), it is characterized in that: described RO membrane cartridge (12) comprises RO membrane filtration bottle (1), RO membrane cartridge (4) is provided with in RO membrane filtration bottle (1), RO membrane filtration bottle (1) comprises filter flask lid (5), bottle (6), described water entry (2) is arranged at filter flask lid (5) middle position, water purification passage (3) is arranged at bottle (6) bottom, one-way check valvegear (8) is provided with in the water purification passage (3) of described bottle (6) bottom.
The further Technological improvement plan of the utility model is:
Described one-way check valvegear (8) comprises L-type housing (81), L-type housing (81) one end is water purification import (82), it is pure water inlet (83) to opposite end, water purification import (82), pure water inlet (83) is provided with Sealed casing pipe (84), the Sealed casing pipe (84) that one-way check valvegear (8) is held by water purification import (82) is tightly connected with water purification passage (3), L-type housing (81) inside is provided with check ball (85), nearly pure water inlet (83) end of check ball (85) is connected with L-type housing (81) inwall elasticity by spring (86), nearly water purification import (82) end of check ball (85) is provided with hollow snap ring (87).
The further Technological improvement plan of the utility model is:
Described one-way check valvegear (8) water purification import (82) end is fixedly connected with water purification passage (3), and pure water inlet (83) end is connected with pressure-pot by PE flexible pipe.
The further Technological improvement plan of the utility model is:
Described water purification passage (3) side is also provided with waste water tunnel (7), waste water tunnel (7) is provided with capillary waste water plug (14).
The utility model compared with prior art, has following obvious advantage:
One, the utility model arranges one-way check valvegear on the water purification passage of the RO membrane cartridge of traditional RO water-purifying machine, the pressure of pressure-pot when not carrying out water purification operation is made to be enclosed in pressure-pot side by check ball, not only water purification can not be back in filter core, it also avoid filter core and bear pressure-pot pressure for a long time, thus raising purifying water effect, also extend the work-ing life of RO film simultaneously.
Two, the waste water tunnel of the utility model bottom the RO membrane filtration bottle of traditional RO water-purifying machine arranges capillary waste water plug, it is outside that the kapillary of waste water in discharge process under the internal pressure of RO filter flask in capillary waste water plug discharges bottle, because capillary diameter is very thin, in RO filter flask water purification discharge process, affect the aquifer yield of water purification passage hardly, thus improve the cleaning water of traditional RO membrane filtration bottle.

Fig. 2 is the utility model RO filter cartridge construction schematic diagram;
Fig. 3 is the utility model one-way check valve structure schematic diagram.
Embodiment
As shown in Figure 1, 2, 3, the utility model comprises water purifier body 9, Combination filter element is provided with in water purifier body 9, described Combination filter element comprises PP cotton filter core 10, active carbon filter core 11, RO membrane cartridge 12 and post active carbon filter core 13 successively, described RO membrane cartridge 12 comprises RO membrane filtration bottle 1, RO membrane cartridge 4 is provided with in RO membrane filtration bottle 1, RO membrane filtration bottle 1 comprises filter flask lid 5, bottle 6, described water entry 2 is arranged at filter flask lid 5 middle position, water purification passage 3 is arranged at bottom bottle 6, is provided with one-way check valvegear 8 in the water purification passage 3 bottom described bottle 6; One-way check valvegear 8 comprises L-type housing 81, L-type housing 81 one end is water purification import 82, it is pure water inlet 83 to opposite end, water purification import 82, pure water inlet 83 are provided with Sealed casing pipe 84, one-way check valvegear 8 is tightly connected with water purification passage 3 by the Sealed casing pipe 84 of water purification import 82 end, L-type housing 81 inside is provided with check ball 85, nearly pure water inlet 83 end of check ball 85 is connected with L-type housing 81 inwall elasticity by spring 86, and nearly water purification import 82 end of check ball 85 is provided with hollow snap ring 87; Described one-way check valvegear 8 water purification import 82 end is fixedly connected with water purification passage 3, and pure water inlet 83 end is connected with pressure-pot by PE flexible pipe; Described water purification passage 3 side is also provided with waste water tunnel 7, waste water tunnel 7 is provided with capillary waste water plug 14.
Composition graphs 1,2,3 sketches the backwash process of filter flask of the present utility model:
In the normal water purification operation process of RO membrane water purifier, in the normal water purification operation process of RO membrane water purifier, former water is successively through the cotton filter core 10 of PP, active carbon filter core 11, RO membrane cartridge 12 and post active carbon filter core 13 combine and filter, when RO membrane cartridge 12 water purification operation, former water enters RO membrane filtration bottle 1 from the water entry 2 of filter flask lid 5, and purify through RO membrane cartridge 4, the water purification passage 3 of former water bottom bottle 6 through purifying enters the water purification import 82 of one-way check valvegear 8, water through purification is also pushed open check ball 85 by hollow snap ring 87 under the effect of the pressure and enters PE flexible pipe by pure water inlet 83, thus enter pressure-pot connection, the waste water simultaneously produced in the former water process of purification, the kapillary 82 of the capillary waste water plug 14 of clamping in waste water tunnel 7 discharges RO membrane filtration bottle 1 outside,
