The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

When the invention is used normally, only one filtering pipeline filters water and supplies water normally, after a period of time, the filtering pipeline is closed by two three-way valves, and the standby filtering pipeline is opened synchronously. The filter is used alternatively, so that zero intermittent filtering work is achieved, a water supply and drainage pipeline does not need to be cut off, and real-time operation of the water supply and drainage pipeline is guaranteed.

The butt joint structure 8 of the water supply and drainage filtering device butt joints the upper filtering tank and the lower filtering tank, and in the butt joint state, the inner wall of the installation sleeve 83 in the butt joint cylinder 81 is in threaded connection with the lower end of the upper water through tank body 3, and the positioning hoop 82 on the installation ring is in tight butt joint with the positioning ring, so that the positioning hoop 82 is clamped and embedded in the positioning ring, and the purposes of tensioning, buckling and fixing are achieved. When the upper filter box and the lower filter box need to be detached, the butting tube 81 is rotated, at the moment, the positioning hoop 82 slides along the positioning ring, the positioning hoop 82 gradually breaks away from the positioning ring along with the descending of the butting tube 81, and finally, the positioning hoop 82 completely breaks away from the positioning ring along with the further descending of the butting tube 81 until the inner wall of the mounting sleeve 83 breaks away from the lower end of the upper water passing box body 3. The detached butting cylinder 81 naturally falls, the lower end face of the mounting sleeve 83 finally falls on the upper end face of the outer fixing ring 51, and the whole cylinder body of the butting cylinder 81 is supported by the outer fixing ring 51 and is freely placed. Through the steps, the upper filter box and the lower filter box can be mounted or dismounted.

Firstly, the water flow flows into the upper filter tank through the water inlet pipe 1, then is filtered for the first time through the upper filter vat 43 in the upper filter tank, flows into the lower filter tank after being filtered, is filtered for the second time through the lower filter vat 6, and finally is discharged through the water discharge pipe 2.

After a period of use, the upper filter box and the lower filter box need to be cleaned, the upper top cover 41 is screwed by the hand holding portion 42, so that the upper top cover 41 is gradually screwed upwards, the whole inner rotary filter body 4 is gradually lifted, the pressure between the positioning slider 410 and the upper end of the dumbbell rotator 73 is gradually reduced, the positioning slider 410 and the dumbbell rotator 73 rotate, due to the elastic action of the first compression spring 45, the elastic connection mechanism, the upper filter barrel 43 and the limiting and butting mechanism are not lifted immediately but naturally fall under the action of self gravity, the pressure between the supporting ring 32 and the annular hanging plate 47 is gradually reduced, meanwhile, in the process of gradually screwing the upper top cover 41, the positioning groove and the positioning ring 321 rotate in the screwing direction, the pressure is gradually reduced, the lower filter box is not moved at this time, but the pressure between the ring frame 62 and the supporting platform 52 is also reduced along with the downward pressure of the upper filter box. The upper top cover 41 is screwed continuously until the upper top cover 41 is separated from the upper water tank body 3, and then the whole internal rotation filter body 4 is lifted out of the upper water tank body 3. At this time, the upper filtering barrel 43 can be cleaned.

Then, the lower filtering barrel 6 is lifted by holding the lifting and pulling pressing column 72, and then the filtering cover 71 is separated from the ring frame 62 by screwing the lifting and pulling pressing column 72, so that the upper end of the lower filtering barrel body 61 is opened, and the lower filtering barrel body 61 can be cleaned.

After cleaning, the lower filtering barrel body 61 and the filtering cover 71 are screwed together, then the lower filtering barrel 6 is clamped in the supporting platform 52 and erected on the supporting platform 52, so that the lower filtering barrel body 61 is suspended, then the internal rotation filtering body 4 is vertically lowered from the center of the top of the upper water passing box body 3 and is placed into the upper water passing box body 3, so that the lifting pressing column 72 extends into the limiting inverted pipe 48, due to the gravity, the upper filtering barrel 43 and the limiting butt joint mechanism naturally droop, so that the ball at the upper end of the rotating dumbbell 73 is embedded into the hemispherical limiting hole of the positioning slider 410, and due to the vertical sliding grooves corresponding to the hanging lugs 411 formed on the inner wall of the limiting inverted pipe 48, the positioning slider 410 slides under the action force between the second compression spring 49 and the dumbbell rotating body 73, and the positioning slider 410 keeps vertical linear movement by the hanging lugs 411 and the vertical sliding grooves.

Then, screwing the top cover 41 again to ensure that the top cover 41 and the upper water tank body 3 are fastened together along with the screwing of the threads, so that the first compression spring 45 presses the compression rod 46, the compression rod 46 transmits acting force to the annular hanging plate 47, and the annular hanging plate 47 is tightly attached to the bearing ring 32; when the upper top cover 41 and the upper water tank body 3 are fastened to a certain degree, the pressure rod 46 gradually moves upwards to compress the first compression spring 45, the first compression spring 45 also has a certain reverse elasticity to the pressure rod 46 at the moment, the acting force of the pressure rod 46 is further downward, the positioning ring 321 surrounds the positioning groove to slide along with the rotation of the internal rotation filter body 4, and the pressure between the positioning ring 321 and the internal rotation filter body is gradually increased until the upper top cover 41 does not rotate. Meanwhile, when the upper top cover 41 and the upper water tank 3 rotate, the positioning slider 410 and the upper ball of the dumbbell rotator 73, the lower ball of the dumbbell rotator 73 and the upper end of the lifting compression column 72 rotate relatively until the top cover does not rotate.

During normal use, if only the upper filter vat 43 and the lower filter vat 6 need to be cleaned, the upper filter vat 43 can be cleaned only by screwing the upper top cover 41 and removing the internal rotation filter body 4, and then the lower filter vat 6 can be cleaned. The docking structure 8 is not operated at all, so that the upper and lower filter tanks are separated. The workload is reduced, and the cleaning time efficiency is greatly improved.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, and not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
