The invention provides a reverse osmosis filter element.
In an embodiment of the present invention, as shown in fig. 1 to 4, the reverse osmosis cartridge includes:
the central tube 10, the peripheral wall of the central tube 10 is provided with a pure water hole 11;
a reverse osmosis membrane 20 wound around the outer circumference of the central tube 10;
the water storage part 30 is provided with a water inlet 31, a water outlet 32 and a water storage cavity 33 communicating the water inlet 31 and the water outlet 32; the water storage component 30 is arranged in the central tube 10, the water inlet 31 is communicated with the lumen of the central tube 10, and the water outlet 32 is communicated with the water outlet end of the central tube 10;
and the one-way conduction device 40 is arranged at the water inlet 31, and the one-way conduction device 40 is conducted towards the water storage cavity 33.
In this embodiment, the reverse osmosis membrane 20 is wound around the central tube 10 to form a reverse osmosis unit having a raw water flow passage and a pure water flow passage, and the pure water flow passage is communicated with the pure water holes 11 of the central tube 10 so that the permeated pure water flows into the lumen of the central tube 10. The reverse osmosis filter element also comprises a shell, the reverse osmosis unit and the central tube 10 are both arranged on the shell, the shell is provided with a raw water inlet communicated with the water inlet end of the raw water flow channel, a pure water outlet communicated with the water outlet end of the central tube 10, and a wastewater outlet communicated with the water outlet end of the raw water flow channel. The shape of the water storage member 30 may be cylindrical or spherical, and the water storage member 30 is not limited herein, and only needs to be located in the lumen of the central tube 10. Water entering the central tube 10 will first enter the water storage chamber 33 and then exit the central tube 10 via the water outlet 32. It can be understood that the pure water flowing out of the central tube 10 from the water storage chamber 33 will not exchange ions with the water in the central tube 10, and the water flowing into the central tube 10 can only flow out of the central tube 10 after entering the water storage chamber 33. The one-way conduction device 40 can be a one-way valve or other conduction structures, and only needs to satisfy that water can only flow into the water storage cavity 33 from the water inlet 31 but cannot flow out. When the water purifying equipment is shut down, ions in the wastewater channel can be diffused to the pure water channel and further diffused into the central tube 10, and because the water inlet 31 of the water storage element 30 is provided with the one-way conduction device 40, water in the water storage cavity 33 can not be subjected to ion exchange with water in the central tube 10; in addition, after the shutdown, the water in the water storage cavity 33 can not be taken out, that is, the water can fill the water storage cavity 33, so that the water in the central tube 10 can not enter the water storage cavity 33 after the shutdown, that is, the ions can not diffuse to the water storage cavity 33 after the shutdown. From this, when water purification unit when the operation again, the first glass of water that the user obtained from water storage chamber 33 can not contain the ion, and the cleanliness factor is higher.
In the reverse osmosis filter element, the water storage part 30 is arranged in the central tube 10, and the one-way conduction device 40 is arranged at the water inlet 31 of the water storage part 30, so that water in the water storage part 30 does not flow back to the central tube 10 any more, namely, the water in the water storage part 30 does not perform ion exchange with the water in the central tube 10 any more, and therefore, when the water purifying equipment is shut down, even if ions in the raw water are diffused into the central tube 10, the ions cannot enter the water storage part 30; because, the back is opened once more to water purification unit, the first glass of water that the user got is the water in the water storage 30 still is the pure water, has reduced the dissolubility impurity content of first glass of water, the purity of first glass of water when having improved system water to water purification system's practicality has been improved.
Specifically, as shown in fig. 1 to 4, the water storage member 30 is disposed in a cylindrical shape extending along the axial direction of the central tube 10, the water inlet 31 and the water outlet 32 are formed at both ends of the water storage member 30, and a water passing gap 12 communicating with the purified water hole 11 is formed between the water storage member 30 and the central tube 10. In this embodiment, the size of the water storage element 30 is adapted to the central tube 10, and it is only necessary to maximize the volume of the water storage cavity 33, and a water passing gap 12 for pure water to flow is formed between the outer wall of the water storage element 30 and the inner wall of the central tube 10 and between the water inlet 31. The pure water enters the central tube 10 from the pure water hole 11, flows to the water inlet 31 of the water storage member 30 along the water gap 12, and finally flows into the water storage cavity 33 through the one-way conduction device 40. Since the water storage member 30 is disposed in a cylindrical shape corresponding to the central pipe 10, the size of the water storage member 30 can be maximized, that is, the volume of the water storage chamber 33 can be maximized, and the volume of the water passing gap 12 can be minimized; from this, shut down the back at water purification unit, the volume of being polluted by the ion can still less in the center tube 10, after water purification unit moves once more, although polluted water can continue to get into water storage piece 30, nevertheless because the volume is less, consequently, the influence to pure water in the water storage chamber 33 is also littleer, and can be effectively diluted by the pure water, thereby can reduce the whole ion content of several cups of water before after water purification unit moves once more, improve the cleanliness factor of several cups of water before, with the holistic practicality of improvement reverse osmosis filter core.
In practical application, as shown in fig. 2 to 4, one end of the central tube 10 corresponding to the water inlet 31 is closed, and one end of the central tube 10 corresponding to the water outlet 32 is in sealing fit with the water storage member 30. In this embodiment, the closed end of the central tube 10 is spaced from the water inlet 31 to allow pure water flowing along the water gap 12 to flow into the water storage chamber 33 smoothly. One end of the central tube 10 forms a water outlet end corresponding to the water outlet 32, a sealing groove extending along the circumferential direction is formed in the outer wall of the water outlet end, and a sealing ring is embedded in the sealing groove so as to realize the sealing matching of the central tube 10 and the water storage member 30 through the sealing ring.
In one embodiment, as shown in fig. 3 and 4, the inner wall of the closed end of the central tube 10 is protruded with a support rib 13 extending along the axial direction, and the support rib 13 abuts against the water inlet end of the water storage member 30. In this embodiment, the protruding internal perisporium of locating center tube 10 of brace rod 13, 13 one ends of brace rod are connected with the end wall of center tube 10 blind end, and the other end butt is in the end of intaking of water storage 30 to form effective support to water storage 30, both make water storage 30 can stabilize the installation in center tube 10, can guarantee the interval of center tube 10 and water storage 30 end of intaking again. In practical application, the number of the support ribs 13 is multiple and the support ribs are arranged along the circumferential direction of the central tube 10 at intervals, so that the support area of the water storage member 30 is increased, and the installation stability of the water storage member 30 is further improved.
In another embodiment, as shown in fig. 2, an abutment rib 34 is protruded from the outer wall of the water storage member 30, and the abutment rib 34 abuts against the inner wall of the central tube 10. In this embodiment, the butt muscle 34 enables the outer wall of water storage component 30 and effectively forms water clearance 12 between the inner wall of center tube 10, avoids the direct butt center tube 10 of outer wall of water storage component 30 to lead to pure water hole 11 to be blockked up, from this, has improved the job stabilization nature of reverse osmosis filter core.
Specifically, the number of the abutting ribs 34 is plural, and the abutting ribs 34 are provided at intervals in the circumferential direction of the water storage member 30. In this embodiment, a plurality of butt muscle 34 set up along the circumference interval of water storage component 30, and pure water hole 11 sets up along the circumference interval of center tube 10 to water clearance 12 also can be followed the circumference extension of water storage component 30, makes a plurality of positions homoenergetic in center tube 10 circumference effectively intake, improves the intake efficiency of pure water, thereby improves the whole work efficiency of reverse osmosis filter core. In practical applications, the abutting ribs 34 include a first abutting rib 342 adjacent to the water inlet 31, and a second abutting rib 343 adjacent to the water outlet 32. By making the first abutting rib 342 and the second abutting rib 343 abut against the center pipe 10, the water storage member 30 as a whole and the center pipe 10 can form the water passing gap 12, thereby improving the water purification efficiency.
Since the central tube 10 is closed at one end, the water storage member 30 is usually installed into the central tube 10 from the outlet end of the central tube 10, and the inlet end of the water storage member 30 is installed into the central tube 10. The abutting rib 34 may increase the difficulty of the water storage member 30 entering the central tube 10, and therefore, a guide inclined plane 341 is formed on one side of the abutting rib 34 facing the water inlet end of the water storage member 30; the guiding slope 341 allows the abutting rib 34 to enter the outlet end of the center tube 10 more smoothly, so that the water storage member 30 can be installed more easily and conveniently. The width of butt muscle 34 can be decreased progressively from the fixed end towards the contact end to reduce the area of contact of butt muscle 34 and center tube 10, thereby reduce the frictional force of butt muscle 34 and center tube 10 in the installation, further reduce the installation degree of difficulty.
In one embodiment, as shown in fig. 2 to 4, the outer wall of the water storage member 30 adjacent to one end of the water outlet 32 is protruded with a rib 35 extending along the circumferential direction of the inner cylinder. In this embodiment, in order to reduce the influence of the wall thickness of the water storage member 30 on the volume of the water storage cavity 33, the wall thickness of the water storage member 30 is reduced as much as possible, but the water storage member 30 is in a high water pressure environment when the water purifying apparatus is in operation, and in order to prevent the water storage member 30 from being damaged by high water pressure, the pressure resistance of the water storage member 30 should be improved. The reinforcing ribs 35 can effectively improve the structural strength of the water storage member 30, thereby improving the pressure resistance of the water storage member 30. In order to avoid the obstruction of the reinforcing rib 35 to the flow of pure water, the reinforcing rib 35 may be disposed at the water outlet end of the water storage member 30, so as to reduce the space occupation of the reinforcing rib 35 to the water passing gap 12. In practical applications, the number of the reinforcing ribs 35 may be multiple and arranged at intervals along the axial direction of the water storage member 30. In addition, the reinforcing rib 35 may be provided with a water passing notch which penetrates in the axial direction, so as to increase the flow rate of pure water in the water passing gap 12.
With reference to the above embodiment of the abutting rib 34, it can be understood that the free end of the abutting rib 34 should protrude from the reinforcing rib 35 and abut against the inner wall of the central tube 10, so that the water passing gap 12 can be formed between the reinforcing rib 35 and the central tube 10, and the flow rate of pure water can be increased.

In this embodiment, the water inlet of the water storage member is cylindrical, and the valve body 41 is in sealing fit with the water inlet through a sealing ring. The valve core 42 can move along the axial direction of the valve body 41, the valve core 42 is provided with a conducting position and a blocking position on the moving track, when the valve core 42 is acted by water flow outside the water inlet hole 411, the valve core 42 moves to the conducting position to open the water inlet, and when the valve core 42 is not acted by the water flow outside the water inlet hole 411, the valve core 42 moves to the blocking position under the action of the resetting piece 43 to close the water inlet, so that the water flow can only push the valve core 42 in one direction to enter the water passing channel 413, and the water flow can only enter the water storage piece in one direction.
Specifically, a support 44 is disposed at a water outlet end of the valve body 41, the reset member 43 is an elastic member, one end of the elastic member abuts against the support 44, and the other end of the elastic member abuts against the valve core 42. In this embodiment, when the valve core 42 is pushed by water flow from the outside, the valve core 42 compresses the elastic member, and at this time, the elastic member has elastic potential energy for restoring the original shape, and when the water flow decreases, the elastic member pushes the valve core 42 to restore the original shape, so that the valve core 42 moves reversely to block the water inlet 411. The inner wall of the water inlet hole 411 is convexly provided with a limiting ring, and the valve core 42 can be in sealing butt joint with the limiting ring through a sealing ring.
