and the phase backside of two drive rods 9 is fixedly connected to sliding block 20, two sliding blocks 20 it is opposite Face is arcwall face, and sliding block 20 is flexibly connected by arcwall face with the inclined-plane on skewback 17, by the setting of sliding block 20, with Facilitate the abrasion for reducing drive rod 9 on skewback 17, the setting of the arcwall face on sliding block 20, so that sliding block 20 is in skewback Sliding on 17 is more smooth, and the surface on two drive rods 9 close to phase backside is fixedly connected with restraining position ring block 18, two limits The opposite side of ring 18 is fixedly connected to spring 1, the surface of one end and rectangle frame 7 far from stop collar 18 on spring 1 It is fixedly connected, by the setting of spring 1, once skewback 17 gradually releases the extruding of drive rod 9, in the bullet of spring 1 Under power effect, semicircle casing 10 can be automatically terminated for the sealed holding of two inlet tubes 5, easy to use, two transmissions The opposite end of bar 9 is fixedly connected to semicircle casing 10, the opposite side of two semicircle casings 10 with it is close on two inlet tubes 5 The surface activity of opposite end connects, and semicircle lantern ring 11 is fixedly connected in the middle part of two 10 opposite sides of semicircle casing, such as Fig. 3 institute Show, rubber pad is all covered on the surface of semicircle lantern ring 11 and the inner wall of semicircle casing 10, for improving sealing performance, Fig. 3 Draw but unlabeled, the opposite face of two semicircle lantern rings 11 offers fixing groove 21, semicircle lantern ring 11 by fixing groove 21 with The surface activity of filter screen 12 connects, and is opened up by fixing groove 21 on semicircle lantern ring 11, enables filter screen 12 quick It is plugged on semicircle lantern ring 11, the left and right sides of two semicircle lantern rings 11 connects with the opposite end activity of two inlet tubes 5 respectively It connects, the opposite side of two semicircle lantern rings 11 is fixedly connected with filter screen 12, while when needing to replace filter screen 12, reversely Internal screw thread ring 16 is rotated, increase internal screw thread ring 16, the transmission through each structure can make two inlet tubes 5 and filter replacement machine Sealed connection between structure 6 is released, and can be replaced to the filter screen 12 on semicircle lantern ring 11, then be followed again Ring filtering uses, and the upper surface of rectangle frame 7 is fixedly connected with screw rod 13, and the surface of close bottom is cased with spring two on screw rod 13 22, the both ends of spring 2 22 are fixedly connected with the upper surface of the lower surface of support plate 14 and rectangle frame 7 respectively, pass through spring two 22 setting steps up engaging between internal screw thread ring 16 and screw rod 13 more so that moving down for internal screw thread ring 16 is hindered Close, when locking, can be stronger, while spring 2 22 also contributes to reducing and hits bring vibration by the external world, guarantees inlet tube 5 The leakproofness connected between 6 structure of filter replacement mechanism, the lower surface of support plate 14 offer the hole two interted for screw rod 13 15, the surface of screw rod 13 is threaded with internal screw thread ring 16, rotates internal screw thread ring 16 manually first, makes internal screw thread ring 16 in screw rod 13 surfaces move down, can be with two in two 17 folding processes of skewback even if moving down with support plate 14 with skewback 17 The opposite end in contact of drive rod 9 simultaneously generates extruding to it, and two drive rods 9 is caused to carry out in opposite directions with respective semicircle casing 10 Movement, two semicircle casings 10 opposite face not in contact with before, by the opposite end of two inlet tubes 5 respectively with two semicircular sleeves The two sides of ring 11 are fitted closely, and backspin internal screw thread ring 16 is then proceeded to, and continue support plate 14 under skewback 17 It moves, so that the surface on the arc-shaped concave and two inlet tubes 5 on two semicircle casings 10 close to opposite end is carried out close Fitting, so far, two inlet tubes 5 realize the effect of sealed connection by 6 device of filter replacement mechanism, when circulating water flow through into When liquid pipe 5, filter screen 12 can be passed through, under the filtration of filter screen 12, can make that following for 4 circulating pump of circulator will be entered Ring water is sufficiently filtered, easy to use, and the lower surface in support plate 14 close to front and back side is fixedly connected to skewback 17, the inclined-plane on two skewbacks 17 is oppositely arranged.

Working principle: the spray scrubber when in use, rotates internal screw thread ring 16 manually first, makes internal screw thread ring 16 in spiral shell 13 surface of bar moves down, can be with two in two 17 folding processes of skewback even if moving down with support plate 14 with skewback 17 The opposite end in contact of a drive rod 9 simultaneously generates extruding to it, and two drive rods 9 is caused to carry out phase with respective semicircle casing 10 To movement, two semicircle casings 10 opposite face not in contact with before, by the opposite end of two inlet tubes 5 respectively with two and half The two sides of circle lantern ring 11 are fitted closely, and backspin internal screw thread ring 16 is then proceeded to, and continue support plate 14 with skewback 17 move down, and so that the surface on the arc-shaped concave and two inlet tubes 5 on two semicircle casings 10 close to opposite end is carried out tight Close fitting, so far, two inlet tubes 5 realize the effect of sealed connection by 6 device of filter replacement mechanism, work as circulating water flow When through inlet tube 5, filter screen 12 can be passed through, under the filtration of filter screen 12, can make, which will enter circulator 4, is recycled The recirculated water of pump is sufficiently filtered, easy to use, while when needing to replace filter screen 12, rotating backward interior spiral shell Line ring 16, rises internal screw thread ring 16, and the transmission through each structure can make between two inlet tubes 5 and filter replacement mechanism 6 Sealed connection released, the filter screen 12 on semicircle lantern ring 11 can be replaced, then again carry out circulating filtration make With solving in actual use, since be difficult to when the cleaning solution of tower body 1 to be recycled will be clear for circulating pump The dust granule adulterated in washing lotion is effectively filtered, and causes the spray orifice in tower body 1 in spray equipment to be easy to cause obstruction, simultaneously Cleaning solution in circulated sprinkling also because to cause to spray clean effect not ideal enough for doping dust granule, reduces working efficiency, To using the problem of making troubles.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
