Description

Technical Field

[0001] This invention relates to the field of RO water purifier technology, specifically to an RO water purifier that is easy to install and disassemble. Background Technology

[0002] With the development of industrialization, water pollution has become increasingly prominent, and drinking water safety is receiving high attention. Because most of the water in our lives contains a variety of impurities or odors and cannot be drunk directly, some even contain a variety of substances that are harmful to health and threaten the lives of drinkers. Ordinary filter cartridges are difficult to filter out impurities in water. RO membranes, also known as reverse osmosis membranes, are usually designed with a through-type structure, that is, water enters at one end and clean water and wastewater exit at the other end.

[0003] Although existing reverse osmosis membranes have wastewater outlets, impurities still remain inside. To avoid secondary pollution, the reverse osmosis membrane needs to be replaced frequently. However, existing reverse osmosis membranes are usually installed inside pipes. When the water purifier is used in a small space such as a kitchen, the pipes cannot be opened and the space above the water purifier is too small to remove the reverse osmosis membrane. Therefore, to replace the reverse osmosis membrane, the water purifier needs to be removed, the membrane replaced, and then the water purifier installed in the cabinet. Replacing the reverse osmosis membrane is quite difficult.

Detailed Implementation

[0026] Please see Figure 1-8 This invention provides a technical solution: an RO water purifier that is easy to install and disassemble, comprising an installation pipe, the installation pipe being composed of a top plate 101, a bottom plate 102, an arc-shaped fixing plate 103, and two arc-shaped sliding plates 104; the top plate 101 is fixedly connected to the top of the arc-shaped fixing plate 103; the bottom plate 102 is fixedly connected to the bottom of the arc-shaped fixing plate 103; the front ends of the two arc-shaped sliding plates 104 are fitted together; the inner diameter of the arc-shaped sliding plate 104 is equal to the outer diameter of the arc-shaped fixing plate 103, and the inner wall of the arc-shaped sliding plate 104 is fitted to the outer wall of the arc-shaped fixing plate 103; the top and bottom of the arc-shaped sliding plate 104 are respectively fitted to the top plate 101 and the bottom plate 102; the top plate 101, the bottom plate 102, the arc-shaped fixing plate 103, and the two arc-shaped sliding plates 104 are concentrically arranged, and the two arc-shaped sliding plates 104 can be connected to the top plate 101 by the arc of the arc-shaped fixing plate 103. The rotating center slides on the outer wall of the arc-shaped fixed plate 103; each of the two arc-shaped sliding plates 104 is fixedly connected to an arc-shaped spring 2 for its reset; a drain plate 3 is fixedly connected to the arc-shaped fixed plate 103, and a first water outlet pipe 4 is fixedly connected to the drain plate 3. The bottom end of the first water outlet pipe 4 passes through the bottom plate 102 and extends to the outside of the bottom plate 102. A second water outlet pipe 5 is fixedly connected to the bottom plate 102; a reverse osmosis membrane 6 is arranged above the drain plate 3, and a purified water outlet pipe 7 is fixedly connected to the bottom end of the reverse osmosis membrane 6. The purified water outlet pipe 7 is threadedly connected to the first water outlet pipe 4. A water inlet pipe 8 is fixedly connected to the top plate 101, and a fixing component is fixedly connected to the top plate 101; the fixing component fixes the reverse osmosis membrane 6 when it is in normal use, and allows the reverse osmosis membrane 6 to be quickly disassembled when it needs to be replaced.

[0027] The fixing assembly includes a sliding sleeve 9, which is rotatably connected to a top plate 101. The top end of the sliding sleeve 9 is polygonal, and the bottom end of the sliding sleeve 9 extends below the top plate 101. A piston 11 is slidably connected to the inner wall of the sliding sleeve 9. A first spring 12 is fixedly connected to the top of the piston 11, and the top end of the first spring 12 is fixedly connected to the sliding sleeve 9. The bottom of the piston 11 has an insertion hole 13 that can be inserted into the top end of the reverse osmosis membrane 6. A first traction rope 14 is wound around the sliding sleeve 9. The bottom end of the first traction rope 14 passes through the side of the arc-shaped fixing plate 103 and extends to the outside of the arc-shaped fixing plate 103. A first slider 15 is fixedly connected to the bottom end of the first traction rope 14. The first slider 15 is slidably connected to the arc-shaped fixing plate 103 in the vertical direction. A second spring 16 for resetting is fixedly connected to the first slider 15. Two second traction ropes 17 are fixedly connected to the first slider 15, and the two second traction ropes 17 are respectively fixedly connected to two arc-shaped sliding plates 104.

[0028] When the above solution is put into actual use, during installation, the inlet pipe 8 is fixedly installed on the water inlet (or tap water inlet pipe), and then the first outlet pipe 4 is installed into the purified water outlet pipe; then the second outlet pipe 5 is installed into the sewage outlet pipe; during use, tap water enters the installation pipe from the inlet pipe 8, and the tap water will enter the reverse osmosis membrane 6 under pressure. After being filtered through the layers of the reverse osmosis membrane, purified water will flow from the inlet outlet pipe 7 into the first outlet pipe 4, and then flow out; some tap water will flow out from the bottom of the reverse osmosis membrane 6. The tap water flowing out from the bottom of the reverse osmosis membrane 6 will carry away impurities in the reverse osmosis membrane 6 and flow out from the bottom of the reverse osmosis membrane 6. Wastewater will flow from the leak plate 3 into the area between the leak plate 3 and the base plate 102, and then flow out from the second outlet pipe 5. When the reverse osmosis membrane 6 needs to be replaced after a certain period of use, first close the tap water inlet pipe so that tap water no longer flows into the inlet pipe 8. Then, the operator rotates the sliding sleeve 9 counterclockwise. The sliding sleeve 9 will drive the reverse osmosis membrane 6 to rotate counterclockwise synchronously through the piston 11. The reverse osmosis membrane 6 will drive the purified water outlet pipe 7 to rotate synchronously. When the purified water outlet pipe 7 rotates counterclockwise, it will slowly disengage from the threads on the first outlet pipe 4. As the sliding sleeve 9 rotates, it will retract the first traction rope 14. The first traction rope 14 will drive the first slider 15 to move in an arc shape. As the first slider 15 slides upwards on the outer wall of the fixed plate 103, the top of the second spring 16 moves upwards, stretching the second spring 16. The first slider 15 also moves one end of each of the two second traction ropes 17 upwards, and the other ends of the two second traction ropes 17 move the two arc-shaped sliding plates 104. The two arc-shaped sliding plates 104 move backwards on the outer wall of the arc-shaped fixed plate 103 (the trajectory of the two arc-shaped sliding plates 104 is a rotation around the central axis of the arc-shaped fixed plate 103, with the radius of the outer wall of the arc-shaped fixed plate 103 as the radius; the arc-shaped sliding plates 104 always remain in contact with the arc-shaped fixed plate 103). (External wall movement), the two arc-shaped fixing plates 103 will gradually open to install the pipe; when the clean water outlet pipe 7 is separated from the first water outlet pipe 4, the two arc-shaped fixing plates 103 move to the farthest position; at this time, the operator will lift the piston 11 a short distance to separate the insertion hole on the piston 11 from the top of the reverse osmosis membrane 6. At this time, the top and bottom ends of the reverse osmosis membrane 6 are no longer fixed, and the operator can move the reverse osmosis membrane 6 horizontally forward; when a new reverse osmosis membrane 6 needs to be installed, the operator will first lift the piston 11, then insert the top of the new reverse osmosis membrane 6 into the insertion hole 13, and connect the clean water outlet pipe 7 at the bottom end of the reverse osmosis membrane 6 with the first water outlet pipe 4;Under the elastic force of the first spring 12, the piston 11 will cause the reverse osmosis membrane 6 and the purified water outlet pipe 7 to tend to move downwards. At this time, the external thread on the purified water outlet pipe 7 contacts the internal thread in the first water outlet pipe 4, and the reverse osmosis membrane 6 is initially fixed (at this time, the reverse osmosis membrane 6 is unstable). Then, the operator can rotate the sliding sleeve 9 clockwise, so that the sliding sleeve 9 drives the reverse osmosis membrane 6 and the purified water outlet pipe 7 to rotate clockwise synchronously through the piston 11. The purified water outlet pipe 7 will move downwards under the action of the thread until the bottom surface of the reverse osmosis membrane 6 is tightly attached to the top surface of the leakage plate 3. At this time, the bottom end of the reverse osmosis membrane 6 is supported by the leakage plate 3, and the top end of the reverse osmosis membrane 6 is supported by the leakage plate 3. Piston 11 provides support, completely fixing the reverse osmosis membrane 6, allowing it to operate stably. The first spring 12 consistently applies downward pressure to the reverse osmosis membrane 6 via piston 11, ensuring better adhesion between the membrane and the drain plate 3, guaranteeing that wastewater can flow completely from the drain plate 3 onto the bottom plate 102. As the sliding sleeve 9 rotates clockwise, it slowly releases the first traction rope 14 it has wound up. After losing the tension of the first traction rope 14, the first slider 15 moves downwards under the elastic force of the second spring 16. The two arc-shaped sliding plates 104 rotate forward under the elastic force of the arc-shaped spring 2. Returning to the initial position, until the two arc-shaped sliding plates 104 move to a position where they are in contact with each other, and the arc-shaped spring 2 can apply pressure to the two arc-shaped sliding plates 104, so that the two arc-shaped sliding plates 104 are tightly in contact, which can ensure that tap water does not leak out, and can ensure that the top and bottom ends of the reverse osmosis membrane 6 are stably fixed, so that the reverse osmosis membrane 6 can work more stably. It should be noted that in this invention, arc-shaped sliding plates 104 and top plate 101, arc-shaped sliding plates 104 and bottom plate 102, arc-shaped sliding plates 104 and arc-shaped fixing plate 103, and the two arc-shaped sliding plates 104 are all provided with A sealing rubber ring is used to ensure that the installed pipe will not leak. This invention configures the installation pipe as a top plate 101, a bottom plate 102, an arc-shaped fixing plate 103, and two arc-shaped sliding plates 104. Through the fixing components, when replacing the reverse osmosis membrane 6, the operator only needs to rotate the sliding sleeve 9 to automatically release the fixation of the reverse osmosis membrane 6, and the two arc-shaped fixing plates 103 can also open automatically. The operator can then directly remove the reverse osmosis membrane 6 horizontally forward. Even if the reverse osmosis membrane 6 is installed in a relatively confined space, it can be easily removed, greatly saving the time required for replacing the reverse osmosis membrane 6.

[0029] As a further embodiment of the present invention, the arc-shaped fixing plate 103 is slidably connected to a sealing baffle 18 in the vertical direction; a third spring 19 for resetting is fixedly connected to the sealing baffle 18; a third traction rope 20 is fixedly connected to the top of the sealing baffle 18, and a winding roller 21 is fixedly connected to the third traction rope 20; the winding roller 21 is rotatably connected to the top plate 101; a first bevel gear 22 is fixedly connected to the rotating shaft of the winding roller 21; the first bevel gear 22 meshes with a second bevel gear 23; and the second bevel gear 23 is fixedly connected to the sliding sleeve 9.

[0030] When the above solution is put into practical use, the setting of the sealing baffle 18 can prevent tap water from entering the reverse osmosis membrane 6 from entering the reverse osmosis membrane 6 after entering between the arc-shaped fixing plate 103 and the arc-shaped sliding plate 104. When the reverse osmosis membrane 6 is working, the tap water will accumulate above the sealing baffle 18 and then enter the reverse osmosis membrane 6. The sealing baffle 18 can also support and fix the reverse osmosis membrane 6, so that the reverse osmosis membrane 6 can work more stably. When the reverse osmosis membrane 6 needs to be replaced, the rotation of the sliding sleeve 9 will drive the second bevel gear 23 to rotate, the second bevel gear 23 will drive the first bevel gear 22 to rotate, the first bevel gear 22 will drive the winding roller 21 to rotate and wind up the third traction rope 20, the third traction rope 20 will drive the sealing baffle 18 to move upward, the sealing baffle 18 will disengage from the reverse osmosis membrane 6, and then the staff can easily take out the reverse osmosis membrane 6.

[0031] As a further embodiment of the present invention, the top surface of the sealing baffle 18 is flush with the top surface of the reverse osmosis membrane 6; during operation, setting the top surface of the sealing baffle 18 to be flush with the top surface of the reverse osmosis membrane 6 can ensure that tap water can completely flow into the reverse osmosis membrane 6.

[0032] As a further embodiment of the present invention, a conical drainage hood 24 is provided between the leakage plate 3 and the second water outlet pipe 5; during operation, the conical drainage hood 24 allows sewage to flow out of the second water outlet pipe 5 more effectively.

[0033] As a further embodiment of the present invention, a wrench 25 is fitted onto the sliding sleeve 9, and the wrench 25 can drive the sliding sleeve 9 to rotate. The front end of the wrench 25 is slidably connected to a handle 26 in the vertical direction. When working, when the operator needs to rotate the sliding sleeve 9, he / she can hold the handle 26 and drive the wrench 25 to rotate through the handle 26, which can reduce the force required to rotate the sliding sleeve 9.

[0034] As a further embodiment of the present invention, a limiting block 27 located on the side of the handle 26 is fixedly connected to the top plate 101; during operation, the limiting block 27 can be used to ensure that the handle 26 is stably stopped on the top plate 101 when the reverse osmosis membrane 6 is removed.

[0035] As a further embodiment of the present invention, sealing blocks 28 are fixedly connected to both of the arc-shaped sliding plates 104; during operation, the sealing plates can better seal the two arc-shaped sliding plates 104.

[0036] Working principle: During installation, the inlet pipe 8 is fixedly installed on the water inlet (or tap water inlet pipe), and then the first outlet pipe 4 is installed into the purified water outlet pipe; then the second outlet pipe 5 is installed into the sewage outlet pipe; during use, tap water enters the installation pipe through the inlet pipe 8, and the tap water will enter the reverse osmosis membrane 6 under pressure. After being filtered through the layers of the reverse osmosis membrane, purified water will flow from the inlet outlet pipe 7 into the first outlet pipe 4, and then flow out; some tap water will flow out from the bottom of the reverse osmosis membrane 6. The tap water flowing out from the bottom of the reverse osmosis membrane 6 will carry away impurities in the reverse osmosis membrane 6, and the sewage flowing out from the bottom of the reverse osmosis membrane 6 will leak out. The liquid flows from the liquid plate 3 into the area between the leakage plate 3 and the bottom plate 102, and then flows out from the second outlet pipe 5. When the reverse osmosis membrane 6 needs to be replaced after a certain period of use, first close the tap water inlet pipe so that tap water no longer flows into the inlet pipe 8. Then, the operator rotates the sliding sleeve 9 counterclockwise. The sliding sleeve 9 will drive the reverse osmosis membrane 6 to rotate counterclockwise synchronously through the piston 11. The reverse osmosis membrane 6 will drive the purified water outlet pipe 7 to rotate synchronously. When the purified water outlet pipe 7 rotates counterclockwise, it will slowly disengage from the threads on the first outlet pipe 4. As the sliding sleeve 9 rotates, it will retract the first traction rope 14. The first traction rope 14 will drive the first slider 15 to move on the arc-shaped fixed plate 1. Sliding upwards on the outer wall of the arc-shaped fixing plate 103, the first slider 15 will drive the top of the second spring 16 to move upwards together, stretching the second spring 16. The first slider 15 will also drive one end of the two second traction ropes 17 to move upwards, and the other end of the two second traction ropes 17 will drive the two arc-shaped sliding plates 104 to move respectively. The two arc-shaped sliding plates 104 will move backwards on the outer wall of the arc-shaped fixing plate 103 (the trajectory of the two arc-shaped sliding plates 104 is about the central axis of the arc-shaped fixing plate 103 as the rotation center and the radius of the outer wall of the arc-shaped fixing plate 103 as the radius, and the arc-shaped sliding plates 104 always keep in contact with the outer wall of the arc-shaped fixing plate 103). (Move), the two arc-shaped fixing plates 103 will gradually open to install the pipe; when the purified water outlet pipe 7 is separated from the first water outlet pipe 4, the two arc-shaped fixing plates 103 will move to the farthest position; at this time, the operator will lift the piston 11 a short distance to separate the insertion hole on the piston 11 from the top of the reverse osmosis membrane 6. At this time, the top and bottom ends of the reverse osmosis membrane 6 are no longer fixed, and the operator can move the reverse osmosis membrane 6 horizontally forward; when a new reverse osmosis membrane 6 needs to be installed, the operator will first lift the piston 11, then insert the top of the new reverse osmosis membrane 6 into the insertion hole 13, and connect the purified water outlet pipe 7 at the bottom end of the reverse osmosis membrane 6 with the first water outlet pipe 4;Under the elastic force of the first spring 12, the piston 11 will cause the reverse osmosis membrane 6 and the purified water outlet pipe 7 to tend to move downwards. At this time, the external thread on the purified water outlet pipe 7 contacts the internal thread in the first water outlet pipe 4, and the reverse osmosis membrane 6 is initially fixed (at this time, the reverse osmosis membrane 6 is unstable). Then, the operator can rotate the sliding sleeve 9 clockwise, so that the sliding sleeve 9 drives the reverse osmosis membrane 6 and the purified water outlet pipe 7 to rotate clockwise synchronously through the piston 11. The purified water outlet pipe 7 will move downwards under the action of the thread until the bottom surface of the reverse osmosis membrane 6 is tightly attached to the top surface of the leakage plate 3. At this time, the bottom end of the reverse osmosis membrane 6 is supported by the leakage plate 3, and the top end of the reverse osmosis membrane 6 is supported by the piston 11. The reverse osmosis membrane 6 is completely fixed and can work stably. The first spring 12 can always apply a downward pressure to the reverse osmosis membrane 6 through the piston 11, which can make the reverse osmosis membrane fit better with the leakage plate 3 and ensure that the sewage can flow completely from the leakage plate 3 to the bottom plate 102. During clockwise rotation, the first traction rope 14, which has been wound up, is slowly released. After losing the tension of the first traction rope 14, the first slider 15 moves downwards under the elastic force of the second spring 16. The two arc-shaped sliding plates 104 rotate forward back to their initial positions under the elastic force of the arc-shaped spring 2 until they move to a position where they are in contact with each other. The arc-shaped spring 2 can apply pressure to the two arc-shaped sliding plates 104, ensuring a tight fit and preventing water leakage. This also ensures that the top and bottom ends of the reverse osmosis membrane 6 are stably fixed, allowing the reverse osmosis membrane 6 to operate more stably. It should be noted that in this invention, sealing rubber rings are provided between the arc-shaped sliding plates 104 and the top plate 101, the arc-shaped sliding plates 104 and the bottom plate 102, the arc-shaped sliding plates 104 and the arc-shaped fixing plate 103, and between the two arc-shaped sliding plates 104; this ensures that the installed pipe will not leak.
