Abstract
Description
- A nozzle for cleaning and rinsing drain conduits and the like.
- The present invention relates to a nozzle of the kind referred to in the preamble of claim 1.
- Such nozzles are used for cleaning and - especially - "unstopping" domestic drains and the like, where the force of the jets of liquid, usually water, issuing from the various jet orifices is sufficient to dislodge and remove dirt adhering to the walls of the drain and obstructing the passage of drain water.
- When such a nozzle, connected to the end of a high-pressure water hose, is pushed down along the drainpipe by pushing the hose into the drain hole, problems arise when the nozzle encounters an obstruction, such as a sharp bend or an end surface of a pipe in a joint facing in the opposite direction. If the user tries to move the nozzle past the obstruction by using more force on the hose, the result will often be that the hose is bent in the end region with the nozzle pointing more or less transversely to the surrounding part of the drain, and further pushing will only make matters worse by more or less wedging the nozzle in the conduit.
- It is the object of the present invention to solve or at least alleviate the above problem, and this object is attained by a nozzle of the kind initially referred to, which according to the present invention exhibits the features set forth in the characterizing clause of claim 1.
- When such a nozzle approaches an obstruction in the drain conduit of the kind indicated above, the bud- or ball--shaped element will move to one side when encountering the obstruction. In this way, the elongated flexible member will also be flexed to the same side, acting as a guide, gently guiding the nozzle proper past the obstruction while also flexing the hose slightly to the extent necessary to allow the nozzle to pass the obstruction.
- The present invention will now be explained in more detail with reference to an exemplary embodiment of a nozzle according to the present invention as shown in the drawings, in which
- Figure 1 shows the nozzle as attached to the end of a high-pressure hose, viewed from one side and partly in section, and
- Figure 2 is a cross section taken along the line II-II in Figure 1.
- The
nozzle 10 shown in the Figures comprises anozzle body 11 with alongitudinal passage 12 connecting the inside of a tube orhose 13 to a number of jet orifices, viz. anaxial jet orifice 14 directed in the forward direction 15 of movement of thenozzle 10 when used for cleaning and/or rinsing the inside of a drain conduit (not shown), such as the drainpipe from a kitchen sink, bathtub or the like, as well as a number - in the example shown three - radial/axial oroblique jet orifices 16 partly directed opposite to said forward direction 15. - The
nozzle body 11 is secured to the tube orhose 13 by means of aferrule 17 or any other suitable means not forming part of the present invention, for which reason further description of such means will not be given in the present specification. - Around the front end of the
nozzle body 11 containing theaxial jet orifice 14 there is secured the inner end of ahelical spring 18, the outer end of which is secured to a bud- or ball-shaped element 19 with arounded surface 20 facing mainly in the forward direction 15. The opposite end or side of the bud- or ball-shaped element 19 is shaped with a frusto-conical surface 21 converging in the opposite direction of the forward direction 15. In an embodiment (not shown) the surface is shaped like a full cone pointing towards thenozzle body 11. - As can be seen from Figure 1, the
spring 18 has open windings, except at the ends, where close windings 22 securely grip plug members 23 and 24 on thenozzle body 11 and the bud- or ball-shaped element 19 respectively, in this manner holding the element 19 securely to thespring 18 and the latter securely to thenozzle body 11. - In use, the
nozzle 10 is inserted together with the forward end of thehose 13 into the open end of the drain conduit to be cleaned or "unstopped", after which thehose 13 is connected to a source of high-pressure liquid, such as water with or without suitable additives. Said source may advantageously be a high-pressure liquid cleaning apparatus of the type supplying liquid at considerably higher pressures than normal water-mains pressure. Jets of high-pressure liquid will then issue from both theaxial jet orifice 14 and the radial/axial jet orifices 16, and these jets will partly dissolve and/or dislodge dirt present in the drain conduit, partly form a liquid stream carrying the dirt thus dissolved and/or dislodged away from the region around thenozzle 10. Further, the rearwardly directed components of the jets issuing from theoblique jet orifices 16 will create a force of reaction opposing the force of reaction of the jet issuing from theaxial jet orifice 14, thus making it easier for the user to hold thenozzle 10 in and move it along the forward direction 15 inside the drain conduit (not shown) . - When the
nozzle 10 during its forward movement in the direction 15 inside a drain conduit encounters an obstacle, such as a pipe bend or an end surface of a pipe in a joint, the bud- or ball-shaped element 19 will tend to avoid the obstruction by moving sideways - i.e. at right angles to the forward direction 15 - taking the forward end of thespring 18 with it. Upon further forward movement, thespring 18, now bent sideways away from the obstruction, will act as a guide guiding thenozzle body 11 past the obstruction, aforward chamfer 25 on thenozzle body 11 itself enabling the nozzle body to pass the obstruction un-entangled by same. Arearward chamfer 26 on thenozzle body 11 acts in a similar manner when moving thenozzle 10 in the opposite direction. - The conical surface 21 on the rearwardly facing end of the bud- or ball-shaped element 19 will deflect the jet of liquid issuing from the
axial jet orifice 14 at such times, as the element 19 happens to be in a suitable position relative to thenozzle body 11, the deflected jet then serving to clean the region around the element 19. If the conical surface is shaped like a full cone (not shown), the liquid issuing from theaxial jet orifice 14 will impinge on the conical surface when the bud- or ball-shaped element 19 is in or close to the position shown, so that the jet will be distributed in the region around the element 19. When the element 19, however, is moved away from the coaxial position shown through a not inconsiderable distance, then the liquid jet from theaxial jet orifice 14 will flow out between the open windings of the spring 18 - or in part hit some of them - and contribute to the cleaning action by impinging on a wall somewhat further forward in the drain conduit, or on dirt obstructing the passage to that wall. This applies, of course, also to the case shown, where the surface 21 constitutes a frusto-conical surface. - In the exemplary embodiment shown and described, the assembly comprising the elongate
flexible member 18, and the bud- or ball-shaped element 19 is constituted by a helical spring with an element attached thereto. It is, however, within the scope of the present invention possible to construct this assembly in other ways or to replace it by an integral member. Thus the elongate flexible part could be constituted by a metal tube made flexible by slitting and stretching in the same manner as so-called expanded metal, a rubber tube with holes or slots, a fluted rubber rod with the flutes aligned with a number of axial jet orifices in the nozzle body, or a number of rubber rods placed around one orifice. The bud- or ball-shaped element could be made integral with the flexible part. If the flexible part is a rubber rod, then the bud- or ball-shaped element could be made integral with the rod and further comprise a permanently attached rigid cap of metal, thus improving the wear resistance.
