DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 6 , the present invention provides a technical solution:

[0032] A water purifier, such as Figures 1 to 3 As shown, it comprises a housing 1, a control panel 2 is fixedly connected to the upper left end of the housing 1, a water outlet pipe 10 is fixedly connected to the lower end of the control panel 2, and a cup stand 3 is fixedly connected to the lower left end of the housing 1;

[0033] A drain pipe 11 is fixedly connected to the lower right end of the shell 1, and a water inlet pipe 4 is fixedly connected to the lower right end of the shell 1;

[0034] A first filter element 8 is fixedly connected to the right side of the housing 1, a second filter element 7 is fixedly connected to the middle of the housing 1, a third filter element 6 is fixedly connected to the left side of the housing 1, an RO membrane 5 is fixedly connected to the upper end of the housing 1, and a connecting pipe 9 is fixedly connected between the first filter element 8, the second filter element 7, the third filter element 6, the RO membrane 5 and the water outlet pipe 10;

[0035] A wastewater filtering mechanism 12 is fixedly connected to the right side of the drainage pipe 11;

[0036] The wastewater filtering mechanism 12 can physically precipitate the wastewater, leaving larger solid particles at the bottom of the barrel, and returning the filtered and cleaner water to the water purifier, thereby greatly reducing the waste of water resources.

[0037] When working, firstly, the control panel 2 is used to control the water to continuously enter the connecting pipe 9 from the water inlet pipe 4. The water in the connecting pipe 9 is squeezed by the water behind and enters the first filter element 8. The first filter element 8 removes impurities such as suspended matter, silt, and rust in the water. The water purified by the first filter element 8 continues to enter the second filter element 7 through the connecting pipe 9. The second filter element 7 further removes impurities such as suspended matter, silt, and rust in the water and prolongs the service life of the third filter element 6. The water purified by the second filter element 7 enters the third filter element 6 through the connecting pipe 9. The third filter element 6 absorbs the foreign color and odor, organic matter, residual chlorine, and heavy metals in the water. , so that the filtered water meets the water inlet requirements of the RO membrane 5, the water purified by the third filter element 6 enters the RO membrane 5 through the connecting pipe 9, and the RO membrane 5 effectively removes harmful substances such as bacteria, viruses, heavy metals, pesticide residues, etc. in the water to achieve the effect of direct drinking. Under the control of the control panel 2, the water purified by the RO membrane 5 flows into the cup at the upper end of the cup table 3 through the connecting pipe 9 and the water outlet pipe 10. The wastewater generated by the purification of each filter element and the RO membrane 5 is discharged into the wastewater filtering mechanism 12 through the drain pipe 11. The wastewater can be recycled by the wastewater filtering mechanism 12, which greatly reduces the waste of water resources.

[0038] As an embodiment of the present invention, Figure 3As shown, the wastewater filtering mechanism 12 includes a wastewater bucket 121, which is fixedly connected to the right side of the drain pipe 11, and a return pipe 122 is fixedly connected to the lower end of the right side of the shell 1. The right part of the drain pipe 11 is an L-shaped pipe, and the L-shaped pipe penetrates and extends to the inside of the wastewater bucket 121. A mesh 124 is fixedly sleeved on the outer wall of the L-shaped pipe on the right side of the drain pipe 11, and a spray shield 123 is fixedly connected to the periphery of the mesh 124. The return pipe 122 is fixedly connected between the upper end of the wastewater bucket 121 and the water inlet pipe 4;

[0039] During operation, waste water is sprayed from the L-shaped tube on the right side of the drain pipe 11 to the upper end of the inner wall of the spray shield 123. The waste water sprayed on the spray shield 123 will flow downward along the inner wall of the spray shield 123 or the outer wall of the L-shaped tube, pass through the mesh 124 and flow to the bottom of the waste water bucket 121, effectively reducing the surge of the L-shaped tube on the right side of the drain pipe 11, and reducing the mixing of the upper clarified water and the sedimentation water at the lower end of the partition 131. When waste water continuously enters the waste water bucket 121, the solid particles mixed in the waste water will be retained at the bottom of the waste water bucket 121 due to gravity. When the waste water entering the waste water bucket 121 reaches the upper end of the waste water bucket 121, it will pass through the reflux pipe 122 and enter the connecting pipe 9 again, thereby greatly reducing the waste of water resources, while reducing the surge when the waste water is collected, and ensuring that the reflux water remains clear.

[0040] As an embodiment of the present invention, Figure 3 As shown, a barrier grid 127 is fixedly connected to the top of the right side of the drain pipe 11, and a limit block 125 is fixedly connected to the right inner wall of the drain pipe 11 below the barrier grid 127, and a hollow ball 126 is movably connected to the upper end of the limit block 125, and the gravity of the hollow ball 126 is smaller than the impact force of the water in the drain pipe 11;

[0041] During operation, when waste water reaches the middle of the L-shaped tube on the right side of the drain pipe 11, the hollow ball 126 on the upper end of the limit block 125 is flushed up. When the waste water flushes the hollow ball 126 to the lower end of the blocking grid 127, the hollow ball 126 is blocked by the blocking grid 127, and the waste water continues to flush into the waste water bucket 121 through the hollow ball 126 and the blocking grid 127. When the water purifier stops working and does not produce waste water, the hollow ball 126 is attached back to the upper end of the limit block 125 due to its own gravity. This arrangement can effectively prevent the backflow of waste water. When the impact force of the water in the drain pipe 11 is greater than the gravity of the hollow ball 126 itself, the water can flush the hollow ball 126 up, forcing the hollow ball 126 to separate from the upper end of the limit block 125, allowing the water to enter the waste water filtering mechanism 12 normally.

[0042] As an embodiment of the present invention, Figures 3 to 5As shown, a partition 131 is fixedly connected to the inner center of the waste water bucket 121, a rotating column 132 is fixedly connected to the upper end of the spray shield 123, a hollow shaft 137 is movably sleeved on the upper end of the rotating column 132, the hollow shaft 137 penetrates and extends to the upper end of the partition 131, and the outer walls of both sides of the hollow shaft 137 are located at the upper end of the partition 131 and are fixedly connected with sealing plates 135, and the upper end outer surface of the partition 131 is provided with connecting ports 134 on both sides, and the upper end outer surface of the partition 131 is provided with a connecting port 134. Both the front and rear ends are fixedly connected with a fan-shaped partition 133, and a baffle 136 is fixedly connected to the clockwise side of the upper end of the fan-shaped partition 133. Grooves 138 are provided on the upper parts of both sides of the rotating column 132, and elastic platinum sheets 139 are fixedly connected to the positions corresponding to the grooves 138 on both sides of the rotating column 132. The middle parts of both sides of the hollow shaft 137 are provided with card slots 1391, and the elastic platinum sheets 139 are carded in the inside of the card slots 1391. The lower end of the waste water bucket 121 is movably connected with a lower end cover 1392;

[0043] During operation, as the amount of wastewater in the wastewater bucket 121 increases, the water spreads to the upper end of the inner wall of the wastewater bucket 121. The wastewater filter mechanism 12 works for a long time, and a large amount of solid particles remain at the bottom of the inner wall of the lower end cover 1392. During the cleaning process of the wastewater filter mechanism 12, the wastewater bucket 121 and the lower end cover 1392 are unscrewed. At the moment when the wastewater bucket 121 and the lower end cover 1392 are twisted, the lower end cover 1392 drives the spray shield 123 to rotate downward, the spray shield 123 drives the rotating column 132 to rotate downward, and the rotating column 132 drives the elastic platinum sheet 139 to rotate downward, and the elastic platinum sheet 139 engaged in the slot 1391 is clamped. The hollow shaft 137 is driven to rotate, and the hollow shaft 137 drives the sealing plate 135 to rotate. When the sealing plate 135 rotates to contact the baffle 136, the sealing plate 135 and the hollow shaft 137 are blocked by the baffle 136 and cannot continue to rotate. At this time, the sealing plate 135 seals the connecting port 134. When the sealing plate 135 contacts the baffle 136, the rotating column 132 is continuously rotated downward, and the elastic platinum sheet 139 is separated from the inside of the card slot 1391 and is squeezed into the groove 138. The elastic platinum sheet 139 separated from the card slot 1391 cannot continue to drive the hollow shaft 137 to rotate, and the rotating column 132 is driven to continue to rotate downward until the wastewater is discharged. The barrel 121 is completely separated from the lower end cover 1392, and the sewage at the bottom of the wastewater filter mechanism 12 can be cleaned at this time. At the same time, the upper clarified water in the wastewater filter mechanism 12 is separated from the lower sewage, which can ensure that the clarified water will not be lost during cleaning, thereby further improving the water-saving efficiency. After cleaning the wastewater filter mechanism 12, the wastewater barrel 121 and the lower end cover 1392 are tightened with each other. When the rotating column 132 is driven upward into the interior of the hollow shaft 137, the elastic platinum sheet 139 is squeezed into the groove 138. When the elastic platinum sheet 139 reaches the position of the card slot 1391, it immediately pops open and is clamped in the card slot 1391. At this time, the elastic platinum sheet 139 The sheet 139 drives the hollow shaft 137 to rotate, and the hollow shaft 137 drives the sealing plate 135 to rotate. When the sealing plate 135 contacts the baffle 136 on the opposite fan-shaped partition 133, the sealing plate 135 and the hollow shaft 137 stop rotating, and the connecting port 134 is fully opened. At this time, the waste water bucket 121 and the lower end cover 1392 are tightened with each other, and a debris removal mechanism 13 is arranged inside the waste water bucket 121. When cleaning, the water on the upper end of the partition 131 can be retained to continue to flow back into the water purifier, avoiding excessive waste of water resources when cleaning the waste water filtering mechanism 12, thereby increasing the utilization rate of water resources and reducing the waste of water resources.

[0044] As an embodiment of the present invention, Figures 4 to 5 As shown, a communication port 134 is provided on the upper surface of the partition plate 131, and a soft magnetic strip 1393 is fixedly connected to the edge of the communication port 134 and the lower edge of the sealing plate 135;

[0045] During operation, when the waste water bucket 121 is separated from the lower end cover 1392, the sealing plate 135 seals the connecting port 134. At this time, the soft magnetic strip 1393 at the edge of the connecting port 134 and the soft magnetic strip 1393 at the lower edge of the sealing plate 135 will be tightly adsorbed together due to magnetic attraction, preventing water from leaking out from the upper end of the partition 131, thereby further strengthening the sealing between the fan-shaped partition 133 and the sealing plate 135.

[0046] As an embodiment of the present invention, as shown in FIG. Figure 3 As shown, the left part of the drain pipe 11 is a soft pipe, and the right part of the drain pipe 11 is a hard pipe;

[0047] During operation, the left part of the drain pipe 11 is a soft tube, and the drain pipe 11 can be freely disassembled and separated from the water purifier. The right part of the drain pipe 11 is a hard tube, and the water in the hard tube can be sprayed on the inner wall of the spray-proof cover 123.

[0048] As an embodiment of the present invention, Figures 1 to 3 As shown, a one-way valve is provided at the connection between the return pipe 122 and the water inlet pipe 4;

[0049] During operation, a one-way valve is provided at the connection between the return pipe 122 and the water inlet pipe 4 to prevent the water in the water inlet pipe 4 from entering the return pipe 122 and hindering the normal water flow of the return pipe 122, and allow the water in the return pipe 122 to smoothly enter the connecting pipe 9.

[0050] As an embodiment of the present invention, Figure 4 As shown, the outer surface of the upper end of the sealing plate 135 is an inclined surface in the counterclockwise direction;

[0051] During operation, when the sealing plate 135 rotates counterclockwise, due to the internal water of the wastewater filtering mechanism 12, the outer surface of the upper end of the sealing plate 135 is inclined in the counterclockwise direction, which can effectively reduce the resistance of the sealing plate 135 to the sealing plate 135 when it rotates, and further reduce the surge of the water flow.

[0052] As an embodiment of the present invention, Figure 3 and Figure 6 As shown, the elastic force of the elastic platinum sheet 139 is greater than the sum of the gravity of the hollow shaft 137 and the sealing plate 135 and the resistance of water to the hollow shaft 137 and the sealing plate 135;

[0053] During operation, the elastic force of the elastic platinum sheet 139 is greater than the gravity of the hollow shaft 137 and the sealing plate 135, so that the rotating column 132 can drive the hollow shaft 137 and the sealing plate 135 to rotate through the elastic platinum sheet 139, so that the sealing plate 135 that seals the connecting port 134 rotates. The elastic force of the elastic platinum sheet 139 is greater than the sum of the resistance of water to the hollow shaft 137 and the sealing plate 135, so that the rotating column 132 can drive the hollow shaft 137 and the sealing plate 135 to rotate in the water through the elastic platinum sheet 139, so that the sealing plate 135 and the connecting port 134 are sealed.

[0054] Working principle:

[0055] During operation, the control panel 2 is first used to control water to continuously enter the connecting pipe 9 from the water inlet pipe 4. The water in the connecting pipe 9 is squeezed by the water behind and enters the first filter element 8. The first filter element 8 removes impurities such as suspended matter, silt, and rust in the water. The water purified by the first filter element 8 continues to enter the second filter element 7 through the connecting pipe 9. The second filter element 7 further removes impurities such as suspended matter, silt, and rust in the water and prolongs the service life of the third filter element 6. The water purified by the second filter element 7 enters the third filter element 6 through the connecting pipe 9. The third filter element 6 absorbs foreign colors and odors, organic matter, residual chlorine, and heavy metals in the water, so that the filtered water meets the water inlet requirements of the RO membrane 5. The water purified by the third filter element 6 The water enters the RO membrane 5 through the connecting pipe 9. The RO membrane 5 effectively removes harmful substances such as bacteria, viruses, heavy metals, pesticide residues, etc. in the water to achieve the effect of direct drinking. Under the control of the control panel 2, the water purified by the RO membrane 5 flows into the cup at the upper end of the cup table 3 through the connecting pipe 9 and the water outlet pipe 10. The wastewater generated by the purification of each filter element and the RO membrane 5 is discharged into the wastewater filtering mechanism 12 through the drain pipe 11. The wastewater can be recycled by the wastewater filtering mechanism 12, which greatly reduces the waste of water resources; the wastewater is sprayed from the L-shaped pipe on the right side of the drain pipe 11 to the upper end of the inner wall of the spray shield 123. The wastewater sprayed on the spray shield 123 will flow along the inner wall of the spray shield 123 or the L The outer wall of the L-shaped pipe flows downward, passes through the mesh 124 and flows to the bottom of the waste water barrel 121, effectively reducing the surge of the L-shaped pipe on the right side of the drain pipe 11, and reducing the mixing of the upper clarified water and the sediment water at the lower end of the partition 131. When the waste water continuously enters the waste water barrel 121, the solid particles mixed in the waste water will be kept at the bottom of the waste water barrel 121 due to gravity. When the waste water entering the waste water barrel 121 reaches the upper end of the waste water barrel 121, it will pass through the reflux pipe 122 and enter the connecting pipe 9 again, thereby greatly reducing the waste of water resources and reducing the surge when the waste water is collected, ensuring that the reflux water remains clear. When the waste water reaches the middle of the L-shaped pipe on the right side of the drain pipe 11, the limit water is put into the drain pipe 11. The hollow ball 126 at the upper end of the stop block 125 is pushed up. When the wastewater pushes the hollow ball 126 to the lower end of the blocking grid 127, the hollow ball 126 is blocked by the blocking grid 127. The wastewater continues to rush into the wastewater bucket 121 through the hollow ball 126 and the blocking grid 127. When the water purifier stops working and does not produce wastewater, the hollow ball 126 is attached to the upper end of the stop block 125 due to its own gravity. This setting can effectively prevent the backflow of wastewater. When the impact force of the water in the drain pipe 11 is greater than the gravity of the hollow ball 126 itself, the water can push up the hollow ball 126, forcing the hollow ball 126 to separate from the upper end of the stop block 125, so that the water can enter the wastewater filtering mechanism 12 normally.As the amount of wastewater inside the wastewater bucket 121 increases, the water spreads to the upper end of the inner wall of the wastewater bucket 121. The wastewater filtering mechanism 12 works for a long time, and a large amount of solid particles remain at the bottom of the inner wall of the lower end cover 1392. During the cleaning process of the wastewater filtering mechanism 12, the wastewater bucket 121 and the lower end cover 1392 are unscrewed. At the moment when the wastewater bucket 121 and the lower end cover 1392 are twisted, the lower end cover 1392 drives the spray shield 123 to rotate downward, the spray shield 123 drives the rotating column 132 to rotate downward, the rotating column 132 drives the elastic platinum sheet 139 to rotate downward, the elastic platinum sheet 139 clamped in the clamping slot 1391 drives the hollow shaft 137 to rotate, the hollow shaft 137 drives the sealing plate 135 to rotate, and when the sealing plate 135 rotates When it turns to contact with the baffle 136, the sealing plate 135 and the hollow shaft 137 are blocked by the baffle 136 and cannot continue to rotate. At this time, the sealing plate 135 seals the connecting port 134. When the sealing plate 135 contacts the baffle 136, the rotating column 132 is continued to rotate downward, and the elastic platinum sheet 139 is separated from the inside of the card slot 1391 and is squeezed into the groove 138. The elastic platinum sheet 139 that has separated from the card slot 1391 cannot continue to drive the hollow shaft 137 to rotate, and the rotating column 132 is driven to continue to rotate downward until the waste water bucket 121 is completely separated from the lower end cover 1392. At this time, the sewage at the bottom of the waste water filter mechanism 12 can be cleaned, and at the same time, the upper layer of clarified water in the waste water filter mechanism 12 is separated from the lower layer of sewage, which can be cleaned during cleaning. It ensures that clarified water will not be lost, further improving the water-saving efficiency; after cleaning the wastewater filtering mechanism 12, the wastewater bucket 121 and the lower end cover 1392 are tightened together, and when the rotating column 132 is driven upward to enter the interior of the hollow shaft 137, the elastic platinum sheet 139 is squeezed into the groove 138, and when the elastic platinum sheet 139 reaches the position of the card slot 1391, it immediately pops open and is carded in the card slot 1391. At this time, the elastic platinum sheet 139 drives the hollow shaft 137 to rotate, and the hollow shaft 137 drives the sealing plate 135 to rotate. When the sealing plate 135 contacts the baffle 136 on the opposite fan-shaped partition 133, the sealing plate 135 and the hollow shaft 137 stop rotating, and the connecting port 134 is fully opened. At this time, the wastewater bucket 121 and the lower end cover 134 are connected. The end covers 1392 are screwed together, and a debris removal mechanism 13 is arranged inside the waste water barrel 121. When cleaning, the water on the upper end of the partition 131 can be retained to continue to flow back into the water purifier, avoiding excessive waste of water resources when cleaning the waste water filtering mechanism 12, increasing the utilization rate of water resources and reducing the waste of water resources; when the waste water barrel 121 is separated from the lower end cover 1392, the sealing plate 135 seals the connecting port 134. At this time, the soft magnetic strip 1393 at the edge of the connecting port 134 and the soft magnetic strip 1393 at the lower end edge of the sealing plate 135 are tightly adsorbed together due to magnetic attraction, preventing the water on the upper end of the partition 131 from leaking out, and further strengthening the sealing between the fan-shaped partition 133 and the sealing plate 135;The left part of the drain pipe 11 is a hose, and the drain pipe 11 can be freely disassembled and separated from the water purifier. The right part of the drain pipe 11 is a hard pipe, which can make the water in the hard pipe spray on the inner wall of the spray shield 123; a one-way valve is set at the connection between the return pipe 122 and the water inlet pipe 4, which can prevent the water in the water in the water inlet pipe 4 from entering the return pipe 122 and hindering the normal water flow of the return pipe 122, so that the water in the return pipe 122 can smoothly enter the connecting pipe 9; when the sealing plate 135 rotates counterclockwise, due to the internal water of the wastewater filtering mechanism 12, the outer surface of the upper end of the sealing plate 135 is a bevel in the counterclockwise direction, which can effectively reduce the sealing plate 135 in the rotation. The resistance of water to the sealing plate 135 during rotation further reduces the surge of water flow; the elastic force of the elastic platinum sheet 139 is greater than the gravity of the hollow shaft 137 and the sealing plate 135, so that the rotating column 132 can drive the hollow shaft 137 and the sealing plate 135 to rotate through the elastic platinum sheet 139, so that the sealing plate 135 that seals the connecting port 134 rotates; the elastic force of the elastic platinum sheet 139 is greater than the sum of the resistance of water to the hollow shaft 137 and the sealing plate 135, so that the rotating column 132 can drive the hollow shaft 137 and the sealing plate 135 to rotate in the water through the elastic platinum sheet 139, so that the sealing plate 135 and the connecting port 134 are sealed. ;
