Definitions

  • the present invention concerns a dust collection container with rigid internal framework supporting an external filtering element for a motorized tool with capacity of suction of the working dust.
  • a common problem with this type of tools consists in the elimination of the working dusts, that for the most part get intaken through a duct which leads toward the outside.
  • Such bags are removable from the machine for their substitution and/or cleaning.
  • the patent application GB 2 343 393 describes a tool comprising a system for the extraction of the dust arranged inside its container which conveys the dust into a box for the collection of the dust.
  • the box for the collection of the dust has holes for the outlet of the air in the upper part of the box, transversally to the direction of the flow of air coming from the tool.
  • a filter is placed in the upper part of the box to correspond with the holes. Once saturated the filter gets replaced.
  • a tool comprising a system for the suction of dust and a container for the collection of dust.
  • Said container is made up of a preferably cylindrical envelope inside of which a filtering element is placed that is also preferably cylindrical, which can be mounted coaxial or be unframed with reference to the container and has a transversal (to the flow of air) extension slightly lower than said envelope.
  • the container has a duct for the inlet of air couplable to the tool and at least one duct for the outlet of air, that is closed by a plug whose opening allows to generate in combination with a suction device a cleaning flow of air for the same filtering element.
  • Object of the present invention is to provide a dust collection container that is efficient, offers an increased filtering capacity, is simple to assemble, light and easy to clean.
  • a dust collection container comprising a first duct for the inlet of air, a second duct for the outlet of air and filtering element, characterised in that said container has a rigid internal framework and said filtering element is arranged in removable way outside said framework and has an internal cavity for the collection of dust and an external filtering portion directly looking at the surrounding environment. It is thus possible to obtain a larger filtering surface, a more efficient circulation of the air with a lower total weight of the container.
  • the user can therefore use the motorized tool more easily and for longer times.
  • Figure 1 shows a sectioned side view of a tool provided with a dust collection container according to the present invention
  • Figure 2 shows a view in section according to the line II-II in Figure 1;
  • Figure 3 shows a view in section according to the line III-III in Figure 1;
  • Figure 4 shows a side section view of the dust container in Figure 1 with closed plug
  • Figure 5 shows a side section view of the dust container in Figure 1 with open plug
  • the tool shown in Figure 1 in the drawings is for example an orbital honing machine comprising a working head 1.
  • the working head 1 comprises a rigid external case 2, in which a set of driving mechanisms for an operating disc or back-up plate 3 (or as an alternative a plate with rectangular or triangular shape) is lodged.
  • the driving mechanisms comprise a driving shaft 4 which operates a fan 5 which has the task to intake the working dust and to send it toward a coupling tube 10.
  • the coupling tube 10 puts in communication the inside of the working head 1 with the external environment.
  • the coupling tube 10 preferably ends with a mouthpiece 11 provided with one seal packing 12.
  • a dust collection container 13 with axis inclined with reference to the working plane, which is made up of a rigid internal framework 30 couplable to a cylindrical external removable filtering element 22.
  • the internal framework 30 is shaped in such a way as to define a first duct 15 for the inlet of air connected with the mouthpiece 10, with which an internal connection element 31 is rigidly connected that is made up of connection plates 39 and of a terminal flange 32 suitable to couple with a closing element 33 and to form a second duct 24 for the outlet of air closed by a removable plug 17.
  • the filtering element 22 is made up of a cylindrical lateral filtering portion 34, of a dust collection cavity 35 and ends 36 couplable with - A -
  • housings 37 and 38 respectively of the internal framework 30 and of the closing element 33.
  • the dust accumulates in the bottom part of the cavity 35 inside the filtering element 22.
  • the suction force induced by said external vacuum means determines the origin of a secondary flow of air. External clean air enters through the external filtering portion 34 and it exits from the duct 24 thus dragging dust particles collected on said external filtering portion 34 which consequently gets partially cleaned.
  • the internal framework 30 allows to obtain several advantages:
  • the first duct 15 has a shape lengthened toward the inside of the cavity 35.
  • This structural solution allows to have shorter connection plates 39 and to accumulate the dust in the cavity 35 without the risk that the same dust obstructs the duct 15.
  • the filtering element 22 can also have non-cylindrical shape: for example it can be with square transversal section.
  • the housings 37-38 in such case must have a shape couplable to the ends 36 of the filtering element
