Ultrasonic self-purifying device
Technical field
The present invention relates to a kind of improvement of purifier, refer in particular to a kind of without periodic replacement filter assemblies, the ultrasonic self-purifying device that use cost is low.
Background technology
Though daily running water had done the processing such as filtration, clarification, sterilization; meet national standards for drinking water quality; but in course of conveying, easily cause secondary pollution because pipeline rusty stain or pipe extravasate into, cause in water containing all kinds of harmful substances such as excessive bacterium, virus, chlorine residue, organic matter, heavy metal, radioactive substances.Water purifier filters out these harmful materials just.All kinds of water purifiers are all to rely on filter core to realize water purification function; say to a certain extent; filter core is water purifier " soul "; but purifier is in long-term use; top layer filter core and filter membrane often can be covered by impurity, have reduced water purification efficiency, have a strong impact on its quality; filter core needs to clean in time or change, otherwise accumulate impurity, very easily breed bacteria, virus cause secondary pollution.
Based on this present situation, we have researched and developed a kind of without periodic replacement filter assemblies, the ultrasonic self-purifying device that use cost is low.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of without periodic replacement filter assemblies, the ultrasonic self-purifying device that use cost is low.
For achieving the above object, the technical solution used in the present invention is: ultrasonic self-purifying device, comprises central processing module, water inlet pipe, tank; Described water inlet pipe inserts tank from the top of tank; The below of described tank is provided with outlet pipe and sewage pipe; Described outlet pipe is communicated with the filter assemblies being arranged in tank; On described sewage pipe, be provided with magnetic valve; Described magnetic valve is in order to cut out and to open sewage pipe; On the outer wall of described tank, be provided with supersonic generator; When work, described central processing module control supersonic generator produces ultrasonic wave, when after supersonic generator work a period of time, need to clear up the sewage in tank time, central processing module control relay makes magnetic valve open sewage pipe, and sewage is discharged from sewage pipe.
Preferably, described filter assemblies, comprises filter core and filter membrane; Described filter membrane parcel filter core.
Preferably, described supersonic generator, comprises ultrasonic wave driver module, oscillating plate; When work, described central processing module control ultrasonic wave driver module drives oscillating plate generation generation of vibration ultrasonic wave.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Ultrasonic self-purifying device utilization of the present invention is arranged on the intense impact that ultrasonic wave that supersonic generator in sink outer walls produces produces the water generates cavitation in tank and can the impurity being attached on filter membrane and filter core is clashed into, be peeled off, thereby reach the effect of clean filter assemblies, and regularly circulation, to ensure the long-term self-cleaning of filter assemblies; The present invention is without periodic replacement filter assemblies, and use cost is low.

detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-5 is ultrasonic self-purifying device of the present invention, comprises central processing module, water inlet pipe 1, tank 2; Described water inlet pipe 1 inserts tank 1 from the top of tank 2; The below of described tank 2 is provided with outlet pipe 3 and sewage pipe 7; Described outlet pipe 3 is communicated with the filter assemblies 5 being arranged in tank 2; On described sewage pipe 7, be provided with magnetic valve 4; Described magnetic valve 4 is in order to cut out and to open sewage pipe 7; Described filter assemblies, comprises filter core and filter membrane; Described filter membrane parcel filter core.Described magnetic valve 4 can be controlled opening or closing of sewage pipe 7; On the outer wall of described tank 2, be provided with supersonic generator 6; In described supersonic generator 6, be provided with oscillating plate (not shown), when work, central processing module control ultrasonic wave driver module drives oscillating plate to vibrate, and produces ultrasonic wave; Ultrasonic wave can become cavity by fluid molecule drawing crack, and by its intense impact producing of breaking, this impact can be clashed into, peel off the impurity being attached on filter membrane and filter core, thereby reach the effect of clean filter assemblies 5, when supersonic generator 6 was worked after a period of time, need to clear up the sewage in tank 2 time, central processing module control relay makes magnetic valve 4 open sewage pipe 7, and sewage is discharged from sewage pipe 7.So regularly circulation, to ensure the long-term self-cleaning of filter assemblies 5.
In the present embodiment, ultrasonic wave driver module adopts CX20106 chip, the P2-2 in its circuit, and the P2-2 of P2-3 and central processing module, P2-3 pin is connected.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Ultrasonic self-purifying device utilization of the present invention is arranged on the intense impact that ultrasonic wave that the supersonic generator 6 on tank 2 outer walls produces produces the water generates cavitation in tank 2 and can the impurity being attached on filter membrane and filter core is clashed into, be peeled off, thereby reach the effect of clean filter assemblies 5, and regularly circulation, to ensure the long-term self-cleaning of filter assemblies 5; The present invention is without periodic replacement filter assemblies 5, and use cost is low.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
