Definitions
- This invention relates to a device for unblocking pipes in general, a typical but not exclusive application of which is in unblocking waste systems of sinks and the like at least partly obstructed by deposits.
- An object of this invention is to provide an efficient functional portable sink unblocking device able to unblock even relatively very clogged pipes without the need to use acid products and/or products requiring external energy sources.
- Another object of the invention is to provide a portable sink unblocking device which is practical, manageable, reliable, small in size and lightweight.
- a further object is to provide a portable sink unblocking device which can also be used by non-expert persons and is hence suitable for example for domestic use.
- a further object is to provide a portable sink unblocking device which is constructionally simple while being of safe and reliable operation.
- the sink unblocking device of the invention consists of a device in which the unblocking action is provided by a compressed air mass which is released instantaneously, to be fed into the pipe to be unblocked in the manner of a shot, such as to create an impact wave which strikes the matter obstructing the pipe.
- the device comprises an air receiver having its inlet connected to a manually operated pumping unit for its filling with compressed atmospheric air, and its outlet comprising a delivery spout to be sealedly engaged with the mouth of a pipe to be unblocked, between said pumping unit and said receiver there being interposed a valve unit able to assume an operative first configuration, or filling configuration, in which it enables the pumped air to accumulate within the receiver, and a second configuration, or emptying configuration, in which it enables the compressed air present in the receiver to discharge instantaneously through said spout.
- Said valve unit which is described in detail hereinafter, assumes said filling configuration automatically, whereas said emptying configuration is set by the user when a pressure considered sufficient has been attained.
- All components are housed in a profiled casing substantially in shape of a gun, the handgrip of said gun shape being equipped with said pumping unit, and its barrel forming said receiver.
- the sink unblocking device of the invention is in the form of a hollow profiled plastic casing having a shape similar to a gun.
- the butt of said gun houses a manually operated pumping unit, described hereinafter, the barrel of the gun forming a receiver for accumulating a compressed air mass drawn from the surrounding atmosphere by said pumping unit ( Figure 2), which then feeds it into the receiver ( Figure 3) via a suitable valve unit.
- a manually operated pumping unit described hereinafter
- the barrel of the gun forming a receiver for accumulating a compressed air mass drawn from the surrounding atmosphere by said pumping unit ( Figure 2), which then feeds it into the receiver ( Figure 3) via a suitable valve unit.
- the handgrip 2 of said hollow casing comprises a cylindrical operating chamber 3 having its free end fitted with a centrally holed threaded cap 4, and its opposite end provided with an elbow-shaped duct 5.
- a pumping piston 33 is slidingly mounted in the operating chamber 3 such that its rod 32 emerges from said cap 4 where it comprises an operating member 31.
- the piston 33 is housed in the chamber 3 with a degree of circumferential slack, and is provided with an annular lip gasket 30 arranged to deform inwards during the return strokes of the piston 33, and to seal against the facing cylindrical surface of the chamber 3 during the outward strokes of the piston 33.
- the connection between the chamber 3 and the external atmosphere is made by a sized hole 44 provided in the cap 4.
- said handgrip 2 is provided with an internally threaded cap-shaped flange 6 which is tightly screwed into the top of the receiver 7, this being of cup shape.
- Said elbow-shaped duct 5 opens at the centre of the base wall of said flange 6, from said base wall there branching a downwardly extending central sleeve 8 of cylindrical shape.
- downstream end of the duct 5 ie that shown at the bottom in the figures, has a greater diameter than its upstream end, the terminal port of said downstream end being surrounded by an annular incision.
- a metal valve seat 55 is inserted as a forced fit into said terminal port, a flanged metal ring 66 being inserted as a forced fit into said annular incision.
- a metal valving element 77 provided with a seal gasket 88 is slidingly housed in said valve seat 66, a compressed spring 99 being provided between said valving element 77 and said ring 66.
- this compressed spring is to facilitate the return of said valving element 77 into its closed position when the piston 33 is stationary or is undergoing a return stroke.
- the arrangement formed by said valving element 77 is basically a non-return valve.
- a valving element 10 is also slidingly mounted in said downwardly extending central sleeve 8 as a precise fit so that it slides freely under sealed conditions, for the filling and emptying operations as described hereinafter.
- Said valving element 10 is in the form of a cylindrical block provided with an angular duct 11 having an upper longitudinal portion 14 which opens into the overlying passage chamber 12 provided between the valving element 10 and the flange 6, and a lower radial portion 13 which opens into the lateral cylindrical surface of said cylindrical block forming the valving element.
- the upper part of said longitudinal portion 14 of the duct 11 has a widening to house a compressed spring 15 positioned between the shoulder formed by said widening and said flanged ring 66.
- said spring 15 is to ensure correct positioning of said valving element 10 at the end of its advancement stroke, where the outer mouth of the radial portion of the angular duct 11 is uncovered, ie lies beyond the free lower end of the sleeve 8.
- said end of-stroke position is defined by the upper end of a tube 16 positioned coaxial to the receiver 7, when in said end-of-stroke position the valving element 10 lying against the upper opening of the tube 16 via a seal element 17, in particular consisting of an embedded frontal gasket fixed thereat by vulcanization.
- Said tube 16 passes beyond the base of the receiver 7, where it comprises a hemispherical head 18 on which an interchangeable spout 19 of elastomeric material is articulated.
- the spout 19, of mushroom shape, is traversed by a longitudinal discharge channel, this latter being upperly provided with a matching seat for engaging said head 18.
- said spout 19 comprises: at the top a spherical cap enabling the device of the invention to be orientated in the desired direction relative to it; in an intermediate position a frusto-conical portion to engage the mouth of a pipe to be unblocked, such as the waste hole of the sink indicated by 20 in Figure 1; and at the bottom a thin-walled downwardly extending sleeve the purpose of which is to close the mouth of the overflow channel 21 of said sink 20 when the air stored in the receiver 7 is discharged through its emptying hole.
- said sleeve acts as a back-flow preventer, to prevent undesired passage of deposits or debris from the U trap 100 of the sink 20 to its overflow channel 21.
- the air is discharged by a trigger 22 pivoted at 23 to the flange 6, and protected by the bridge 124.
- Said trigger 22 is provided with a small vent valve 24, shown as a soft rubber plug, which by means of a spring 122 acting on the trigger 22 is constantly urged elastically against the outer mouth of a channel 25 which connects the outer cylindrical surface of said flange 6 to the aforedescribed passage chamber 12.
- the described device operates in the following manner.
- the trigger 22 is maintained in the closed position shown in Figures 2 and 3, with the valving element 10 closing by means of its element 17 the discharge mouth of the tube 16.
- This latter closure is achieved initially by the thrust of the spring 15, which maintains the valving element 10 pressing against the upper mouth of the tube 16 to allow air to be fed under pressure into the chamber 12, and subsequently by the pressure of the air which has been fed into the chamber 12, to act on the upper face of the valving element 10. Consequently during pressurization of the receiver 7, the discharge tube 16 remains closed whereas the duct 11 remains open.
- the spout 19 is engaged with the pipe to be unblocked (see Figure 1) and the trigger 22 is then operated.
