The working principle is as follows: when the blowoff valve with the dirt collection function is used, firstly, as shown in fig. 1-8, the valve is opened, the first filter screen 8 can effectively filter large particle impurities in the sewage, when the first filter screen 8 is blocked, the first filter screen 8 can slide along the inner wall of the lower valve seat 1 under the action of water flow impact, so that the flow guide hole 9 is opened, the sewage can fill the impurities blocked outside the first filter screen 8 into the collection seat 6, meanwhile, the impeller 20 can drive the shaft lever 19 and the reciprocating screw rod 21 to synchronously rotate under the action of water flow impact, at this time, the knocking block 1901 can knock the first filter screen 8, so as to promote the peeling of the impurities outside the first filter screen 8, meanwhile, the reciprocating screw rod 21 can drive the movable seat 22 to reciprocally slide on the inner side of the collection seat 6, so that the filter plate 23 can push the impurities to the left end of the collection seat 6, so that the subsequent blocking plate 15 can rotate under the action of gravity for filtering out the impurities, thereby realize the automatic emission of the ration to impurity, second filter screen 25 can carry out the secondary filtration to the sewage in collecting seat 6 simultaneously to flow in lower valve seat 1 once more through back flow 7, thereby accomplish a series of work.
Those not described in detail in this specification are well within the skill of the art.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
