Description
Technical Field
The invention relates to a water purifier, in particular to a water purifier capable of automatically cleaning a filter element.
Background
Along with the deterioration of the environment, the cleanliness of a water source is lower and lower, and urban water is required to be treated and purified to reach the use standard; meanwhile, the requirement of people on drinking water is higher and higher, and more families buy water purifiers to purify the water quality; the common water purifier is divided into a water inlet and a water outlet and a water inlet and a water outlet, the water purifier with the water inlet and the water outlet cleans a filter element by utilizing a domestic water pipeline, and looks advanced and scientific, but the water purifier can only clean the surface of the filter element and cannot deeply clean, more dirt and impurities still exist in the filter element, and the dirt can deteriorate after long-term use, so that the drinking water health of people is seriously influenced, therefore, the overall purification effect does not have great advantages, and meanwhile, the water purifier with the water inlet and the water outlet is troublesome to install, and meanwhile, the water pipe in a room is complicated, so that the simplicity and the attractiveness of the room are influenced; and traditional one advances the water purifier of one play formula with raw water output purified water behind the multi-layer filtration, because unable independently clean, this kind of water purifier needs frequent renew cartridge in the use, this makes user's later stage input increase, also influences the convenience of using simultaneously.
Disclosure of Invention
Aiming at the problems, the invention provides a self-cleaning water purifier which can automatically and deeply clean an internal filter element, effectively prevent dirt from being left for a long time, effectively prolong the service cycle of the filter element and effectively improve the use experience of the water purifier.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the self-cleaning water purifier comprises a water purifying tank, a water inlet, a water outlet and a water purifying port; the water inlet is arranged on the top plate of the water purifying tank, and the water outlet and the water purifying port are arranged on the bottom plate of the water purifying tank; a cylindrical filter element is arranged on a vertical axis in the water purifying tank, and the top surface and the bottom surface of the filter element are respectively opposite to the water inlet and the water purifying port; two symmetrical and horizontally movable piston sheets are also arranged in the water purifying tank, and the movement of the piston sheets is controlled by a driving support rod fixed on the side wall of the water purifying tank; the filter element is characterized in that an extrusion piece is vertically arranged in the filter element and is connected with an elastic piece through a horizontal connecting rod, and the elastic piece is positioned on the side face of the filter element, which is just opposite to the piston piece.
The invention has the beneficial effects that: in a natural state, the driving support rod is in a retracted state, the two piston sheets are close to the side wall of the water purifying tank, and a gap is formed between the piston sheets and the filter element; when purified water is needed, the water purifying port is opened, the water outlet is closed, the driving support rod is extended to enable the piston sheet to be tightly attached to the filter element, and the piston sheet presses the elastic sheet and tightly clamps the filter element; raw water flowing in from the water inlet can only permeate the filter element layer by layer, the raw water purified by the filter element finally flows out from the water purifying port, and impurities in the raw water are retained at the filter element; when the domestic water is needed, the water outlet is opened, the water purifying port is closed, the driving support rod is retracted to enable the piston sheet to be close to the side wall of the water purifying tank, raw water flowing in from the water inlet enters the water purifying tank and flows through a gap between the filter element and the piston sheet, and the raw water is finally discharged from the water outlet; when raw water flows between the filter element and the piston plate, the water flow channel becomes narrow, the water flow speed is obviously accelerated, and the static pressure at the position is reduced according to the Venturi effect, so that the elastic sheet deforms under the action of pressure difference, the deformed elastic sheet drives the connecting rod to displace, and the connecting rod pulls the extrusion plate to move, so that the extrusion plate extrudes the filter element; the pressure intensity at the spring plate changes greatly at the moment of water flow on and off, so the movement amplitude of the extrusion plate is large, and the extrusion and purification strength of the filter element is high; therefore, when the domestic water is used each time, the self-cleaning water purifier extrudes and cleans the filter element, so that impurities on the surface and in the filter element are not retained for a long time but are discharged along with the domestic water, and the filter element can work longer and cleaner.
Preferably, the water inlet is provided with a turbulent flow runner which is an asymmetric impeller; the raw water that the water inlet flowed into drives the turbulent flow runner rotates, because the blade of turbulent flow runner is asymmetric, consequently the water pressure periodicity that flows into in the water purification case suddenly high or suddenly low, and the deformation of shell fragment can be promoted to the water pressure of periodic variation to promote the extrusion of filter core and purify.
Preferably, the filter element is formed by stacking three layers of purification materials made of different materials, and an extrusion sheet, a connecting rod and an elastic sheet are arranged in each layer of purification material; the three layers of purification materials can deeply filter raw water, and the cleanness degree of the raw water is improved.
Preferably, a vibration spring is arranged between each group of the pressing sheets; so as to prolong the extrusion effect of the extrusion piece, promote the vibration of the extrusion piece at the same time and further improve the purification effect of the extrusion piece on the filter element.
