Working principle and using flow:
When the water purifier is used, a water source can be input into the front water purifying tank 1 through a water source water inlet at the side of the front water purifying tank 1, filtered by the front water purifying tank 1, then enters the inside of the first-stage reverse osmosis component 2 through the water pipe 4 to carry out first-stage reverse osmosis treatment, enters the inside of the second-stage reverse osmosis component 3 through the delivery of the water pipe 4 to carry out second-stage reverse osmosis treatment, and finally is led out through the water pipe 4 to finish the whole pure water purifying process;
When the filter screen 10 in the front water purifying tank 1 is partially blocked and needs to be cleaned, an external water pipe is communicated with the top end of the four-way valve 5, external water flow is pressurized and then introduced into the four-way valve 5 and is led out through the bottom end of the four-way valve 5, and at the moment, the water flow can enter through the top end of the power tank 701 and is led out through the nozzle 702 at the bottom end of the power tank 701 and acts on the top end of the filter screen 10 to flush the surface of the filter screen;
Meanwhile, when water flows into the power tank 701, the water flowing at high speed can push the impeller 704 to rotate, at the moment, the main shaft 703 rotates along with the impeller, and drives the first connecting rod 705 to rotate, and when the first connecting rod 705 rotates, the second connecting rod 706 can also apply pulling force and pushing force, at the moment, the second connecting rod 706 applies acting force to the mounting block 114 along with the impeller, so that power transmission is completed;
When the mounting block 114 receives the acting force from the second connecting rod 706, the mounting block 114 is vertically displaced under the guiding action of the longitudinal guide rail 8, namely, the mounting block 114 is vertically reciprocally displaced, the mounting plate 121 is synchronously moved, the connecting rods 124 are deflected when the mounting plate 121 is downwardly displaced, namely, the included angle between the two connecting rods 124 is increased, the two second fixing seats 123 are relatively far away, the guide block 125 at the bottom end is driven to be relatively far away, the two cleaning brushes 13 are finally driven to be relatively far away, the top ends of the filter screens 10 are brushed, the two cleaning brushes 13 are relatively close when the mounting plate 121 is lifted, the top ends of the filter screens 10 are likewise brushed, and the cleaning process can be automatically realized by matching with the water flow sprayed by the power assembly 7;
When the mounting block 114 is upwardly displaced under the action of the power assembly 7, the piston rod 113 and the piston plate 112 can be driven to synchronously upwardly displace at the moment, namely negative pressure is generated in the water pumping pipe 111, at the moment, water flow at the bottom end of the inner cavity of the front water purifying tank 1 can be sucked into the water pumping pipe 111 through the water pumping valve 115, and when the mounting block 114 is downwardly displaced under the action of the power assembly 7, the water flow in the water pumping pipe 111 is led out through the drain valve 116 at the moment, and is conveyed through the circulating pipe 6 to re-enter the interior of the four-way valve 5, and is led out through the bottom end of the four-way valve 5, so that secondary recycling is finished, and the use of water resources is reduced.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
