The positive face interval setting for permeating diaphragm, to ensure that the water velocity in pure water channel；Similarly, it is installed in intake tunnel
The adjacent two layers interval to spiral reverse osmosis membrane can be arranged for water inlet grid, also ensure that intake tunnel in this way
Interior water velocity.
It should be noted that external raw water only passes through original water inlet 13 and enters in shell 10, this is allowed in shell 10
The water flow of the position of neighbouring original water inlet 13 is not only big, but also water flow velocity is also than very fast；That is, passing through original water inlet 13
Raw water into shell 10, it is most of that reverse osmosis membrane is flowed through by the position of 22 face original water inlet 13 of reverse osmosis membrane group
Group 22, this results in the water for flowing through position of the reverse osmosis membrane group 22 far from raw water mouth fewer, so as to cause reverse osmosis membrane
Piece group 22 is intake unevenly, not only influences the filter efficiency of reverse osmosis membrane group 22 in this way, while also shortening reverse osmosis membrane
The service life of group 22.
In view of the above problem, in an embodiment of the present invention, it is additionally provided with flow-guiding structure 30 in the shell 10, the water conservancy diversion
Structure 30 is arranged adjacent to original water inlet 13, is mainly used for being directed through water that original water inlet 13 enters in shell 10 along raw water
The Radial Flow of import 13.
When reverse-osmosis membrane element 100 is filtered work, external raw water is entered in shell 10 by original water inlet 13,
And enter the raw water in shell 10 under the guide functions of flow-guiding structure 30, from original water inlet 13 along the diameter of original water inlet 13
To far from original water inlet 13 direction flow, this be to ensure that reverse osmosis membrane group 22 adjacent to the end of original water inlet 13 into
Water is uniform, to take full advantage of reverse osmosis membrane group 22, not only increases the filter efficiency of reverse osmosis membrane group 22 in this way, together
When reverse osmosis membrane group 22 can also be avoided to cause its service life too short problem to occur due to its water inlet is excessively concentrated at one.
In one embodiment of this invention, which is made of multiple fuisw ribs 31 and a water fender 32.Wherein,
Multiple fuisw ribs 31 are set to the inner wall of shell 10, referring to figure 2., it is preferable that multiple fuisw ribs 31 are set to the interior table of end cap 15
Face, multiple radially extending along original water inlet 13 of fuisw rib 31, and multiple fuisw ribs 31 are also along the week of original water inlet 13
It is arranged to interval, this allows for adjacent two fuisw rib 31 and shell 10 encloses to set together and forms diversion trench, which mainly uses
It is flowed in guiding raw water from original water inlet 13 to the direction far from original water inlet 13.
Water fender 32 is set in shell 10, and the setting of face original water inlet 13 is simultaneously spaced setting with shell 10, main
Raw water for stopping to enter to from raw water mouth in shell 10, straight to avoid the raw water entered to by raw water mouth in shell 10
Flow to reverse osmosis membrane group 22.
When raw water enters in shell 10 from original water inlet 13, raw water by water fender 32 blocking and along original water inlet
13 Radial Flow, and raw water in the case where adjacent two fuisw rib 31 encloses the guide function for setting the diversion trench to be formed with shell 10 to remote
Direction flowing from original water inlet 13, avoids the flow direction of raw water straight entered in shell 10 from original water inlet 13 in this way
Reverse osmosis membrane group 22, and make reverse osmosis membrane group 22 only have subparticipation filtering, and then lead to reverse osmosis membrane group 22
The problem that filter efficiency is low and service life is short occurs.
It should be noted that the water fender 32 can be fixed on multiple fuisw ribs 31 adjacent to the one of reverse osmosis membrane group 22
Side can also be fixedly installed in shell 10 by other connectors, how to be fixedly mounted and do not done specifically to water fender 32 at this
Restriction.
Further, multiple fuisw ribs 31 are recessed along direction clockwise or counter-clockwise and arc-shaped is arranged.Specifically
, referring to figure 2., in an embodiment of the present invention, multiple fuisw ribs 31 are recessed along clockwise direction, this is allowed for by phase
Two adjacent fuisw ribs 31 enclose the diversion trench for setting and being formed with shell 10 together and are also bent along clockwise direction.When raw water is led along this
When chute flows, which not only has the radial flow velocity along original water inlet 13, while also having the week along original water inlet 13
To flow velocity；That is, forming eddy flow under the guide functions of multiple fuisw ribs 31 into the raw water in shell 10.This just makes
Obtaining into the raw water in the intake tunnel of reverse osmosis membrane group 22 not only has the speed axially flowed along reverse osmosis membrane group 22
Degree, while also there is the speed flowed along the extending direction of intake tunnel；That is, the water inlet of reverse osmosis membrane group 22 is logical
Raw water in road also forms eddy flow effect, and impurity, the booty being stranded in intake tunnel are easier under the action of eddy flow raw water
It is rushed out intake tunnel, impurity, the booty that can be thus stranded in intake tunnel to avoid reverse osmosis membrane group 22 block up
Plug, and then it is conducive to extend the service life of reverse osmosis membrane diaphragm group, namely be conducive to extend the use of reverse-osmosis membrane element 100
Service life.
Further, multiple fuisw ribs 31 are circumferentially uniformly distributed along original water inlet 13, that is to say, that the two of arbitrary neighborhood lead
Spacing between stream muscle 31 is consistent, i.e., any two adjacent fuisw ribs 31 and shell 10 enclose the size for setting the diversion trench to be formed
Quite.This allows for the raw water after being stopped by water fender 32 under the guide functions of multiple fuisw ribs 31, uniformly flows to raw water
The surrounding of import 13, so that reverse osmosis membrane group 22 can intake adjacent to each position in one end of original water inlet 13, and
And amount of inlet water is suitable, ensures that reverse osmosis membrane group 22 can filter raw water everywhere in this way, to ensure that reverse osmosis
The filter efficiency and service life of diaphragm group 22.
It is arranged it should be noted that central tube 21 stretches out reverse osmosis membrane group 22 adjacent to one end of original water inlet 13, also
It is to say, when center tube assembly 20 is installed in shell 10, central tube 21 is abutted adjacent to one end of original water inlet 13 with shell 10, with
So that the preset clearance between raw water mouth of reverse osmosis membrane group 22.In view of the positioning between central tube 21 and shell 10, at this
In one embodiment of invention, referring to figure 2., multiple fuisw ribs 31 enclose to set adjacent to one end of original water inlet 13 to form a slot together
40, the size and the sizableness of central tube 21 of the slot 40, this allows for the central tube 21 can be by being plugged to slot 40
In and be fixedly connected with shell 10.
But when central tube 21 is inserted in slot 40, which is just directly connected to original water inlet 13, this just makes
Raw water not by filtering be just discharged from central tube 21, it is contemplated that the above problem please refers to Fig. 1, the central tube 21 adjacent to raw water into
The side wall 14 of one end of mouth 13, which runs through, to be had along its circumferentially distributed multiple water hole 212；It is spaced and is arranged with original water inlet 13 simultaneously

The pipeline of pipe 21 separates, and ensures that the raw water entered in shell 10 from original water inlet 13 cannot directly enter to central tube 21
It is interior.
In 100 Pure-water Making of reverse-osmosis membrane element, external raw water is entered in shell 10 by original water inlet 13, and edge
The axial flowing of central tube 21, after the blocking of the water fender 32 in raw water acceptor center pipe 21, the raw water in central tube 21 is only
It can be flowed by multiple water holes 212 on central tube 21 to the surrounding of central tube 21, and flow out the raw water of central tube 21
Continue to flow to the direction far from central tube 21 under the action of multiple fuisw rib 31, so that shell 10 is adjacent to original water inlet
13 one end is each filled with raw water, and then ensures that reverse osmosis membrane group 22 is uniform adjacent to the water inlet of one end of original water inlet 13.
It should be noted that usual one end of central tube 21 of reverse osmosis membrane group 22 needs to block, water fender 32 is arranged
In in central tube 21, not only facilitating the fixation of water fender 32 in this way, while the structure of shell 10 can also be simplified.
In above-described embodiment, multiple fuisw ribs 31 are with shell 10 using integrated molding setting.So set, not only ensure that
