The technical solution of the utility model is: a kind of filter with backwashing function, comprise feed tube, drain pipe, cleaning hose and filter, described filter also arranges two jockeys, wherein, the first jockey connects the liquid feeding end of feed tube and filter, and the second jockey connects the outlet end of drain pipe and filter; The end that feed tube is connected with the first jockey is provided with blow-off pipe, and feed tube, drain pipe, cleaning hose and blow-off pipe are provided with hand-operated valve; One end of described cleaning hose is connected with feed tube, and the other end is connected with drain pipe; Be provided with spring in the end housing body that filter is connected with the first jockey.
Preferably, described the first jockey comprises the first mount pad and the first plug that connects as one with the first mount pad, and the liquid feeding end of filter is connected with the first plug; The second jockey comprises the second mount pad and the second plug that connects as one with the second mount pad, and the outlet end of filter is connected with the second plug.
Preferably, be provided with linkage between the first plug and the second plug, filter is fastened between the first plug and the second plug by linkage.
Preferably, linkage comprises connecting rod and bolt, and connecting rod in the installing hole that the first plug and the second plug arrange, connects the first plug and the second plug by bolted.
Preferably, be provided with installing hole on the first mount pad and the second mount pad.
Preferably, filter comprises housing and the filter core of crossing that is arranged on enclosure interior, and the liquid feeding end of crossing filter core is connected with the first plug, and the outlet end of crossing filter core is connected with the second plug.
Preferably, spring fitting is between the liquid feeding end and the first plug of crossing filter core.
The beneficial effects of the utility model are: the utility model is simple and reasonable, low cost of manufacture, easy to use, by two jockeys that arrange filter is installed between feed tube and the drain pipe, filter replacement is convenient, and by cleaning hose filter is carried out backwash, removed the materials such as the impurity that adheres on the filter core and particle, effectively solved the problem that filter core stops up of crossing, when carrying out backwash, only need close valve on feed tube and the drain pipe, the valve of opening on cleaning hose and the blow-off pipe gets final product, and is simple to operate.
