The specific embodiment
Specify the structure of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2 and Fig. 3; A kind of self-cleaning filter device with dirt sucking tube; Comprise the electronic blowoff valve of a housing 6, a blind flange 10, a filter screen 8, a dirt sucking tube 7, a control cabinet 2, one 9, power motor 1, a water inlet 5 and a delivery port 4, blind flange 10 is fixed on the housing 6; Filter screen 8 is arranged in the housing 6, and the upper end is fixing with housing 6 through upper platen assemblies 11, and the lower end is fixing with housing 6 through lower platen assembly 12; Dirt sucking tube 7 is arranged on filter screen 8 inboards; Dirt sucking tube 7 is communicated with electronic blowoff valve 9, and electronic blowoff valve 9 is fixed on the blind flange 10, is electrically connected with control cabinet 2; Water inlet 5 is arranged on housing 6 bottoms, and delivery port 4 is arranged on housing 6 sidewalls; Power motor 1 is fixed on the blind flange 10, and the power transmission shaft of power motor 1 passes blind flange 10 and is connected 7 rotations of drive dirt sucking tube with dirt sucking tube 7 through the steady pin locking, and power motor 1 is electrically connected with control cabinet 2.
