Definitions

  • the present invention relates to the field of vacuum cleaners sled or tank type, or more generally to any suction device intended for cleaning.
  • the present invention relates to particular means allowing to adapt a filter intended to collect dust on a vacuum cleaner.
  • vacuum cleaners which are equipped with a suction turbine, and a hose fitted with a dust extraction cleaning tool.
  • the vacuum cleaner hose is removable and it has a tubular end which is adapted to be connect to an opening on the vacuum cleaner itself.
  • the pipe and the turbine are connected by a dust filter.
  • the opening of the vacuum cleaner intended to connect with the hose is related with the dust filter.
  • the dust filter is, for example, constituted by a bag made of paper mounted on a cardboard or cardboard collar and inserted by the user in the dust filter receptacle, in the vacuum cleaner.
  • the dust filter lets the suction air from the turbine and has an orifice fitted with a flap to let dust sucked in from the paper bag enter the cleaning tool and transferred through the vacuum cleaner hose to the filter dust.
  • Document FR-A-1 071 345 describes a vacuum cleaner comprising a hose and a housing for a dust bag.
  • the dust bag has a filling opening with a removable connection means to the filling pipe, such as a threaded ring secured to the bag around the orifice filling.
  • vacuum cleaners Some models of vacuum cleaners are designed so that they do not only work if they recognize certain types of filters. It's the case especially when the dust bag is mounted on a cardboard.
  • the vacuum cleaner may include a switch or an inhibitor device which prevents its functioning (its starting) as long as the cardboard mounted on the dust bag is not properly engaged. Such a safety prevents aspiration into the dust bag receptacle when it is not installed.
  • This realization has the advantage of being able to use the dust with any type of vacuum cleaner, since it suffices to secure the bag on a cardboard suitable for the vacuum cleaner.
  • a vacuum cleaner in which a dust bag is removably mounted on a adapter.
  • the latter comprises a plate provided with a coincident opening with the interior of a cylindrical protuberance integral with this plate. then mounting the bag on this plate, the protrusion enters the opening of the bag with dust.
  • the assembly is then disposed in a reversible and removable manner on slides 32 located on the wall of the vacuum cleaner surrounding the orifice air inlet.
  • the plate being adapted to the slides, themselves adapted to the vacuum cleaner, the assembly then remains specific to a vacuum cleaner, even if different types of bags can be used.
  • the object of the invention therefore aims to remedy the aforementioned drawbacks and allow the user to dispense with the filters dust specifically designed for the vacuum cleaner used.
  • the user can adapt the connecting tube according to the invention to a support, for example a cardboard box, connect a dust bag to it and install the dust filter thus formed in the vacuum cleaner.
  • a support for example a cardboard box
  • the connection means of the connecting tube makes it possible to reuse the same connecting tube with the bags used successively. Way to fixing allows the connection tube to be secured to the support.
  • the connecting tube 4 according to the invention is intended to be used with a dust bag 6 to make an adaptable universal filtration device in most vacuum cleaners.
  • a vacuum cleaner has a receptacle 13 provided to receive the dust bag 6 and a filling pipe 14, such as shown in Figures 1, 2 and 3.
  • the receptacle 13 of the vacuum cleaner comprises a filling tube 14 of the dust bag 6 with a diameter and a length which fluctuate according to the models. Sometimes it is made up of a simple collar. It is used to transfer the air flow sucked in by the vacuum cleaner turbine and charged with dust collected by the vacuum cleaner’s broom, towards the dust bag 6.
  • FIG 8 there is shown the detached perspective view of a state of the art dust filter comprising a bag 77 made of paper and one end 74 of which is glued to a cardboard 70 with a hole central 73.
  • the cardboard is generally made of a relatively cardboard flexible which is stuck on a folded paper bag.
  • the latter by collage on the zone 75 around the filling orifice 76, represented between the contour in mixed lines and the edge of the orifice 76, is mounted on the rear face of the cardboard box 70 and constitutes with the cardboard box, a dust filter traditional.
  • the accessory according to the invention consists of a connecting tube 4 comprising a first end 21 capable of being secured to substantially sealed by means of attachment 3 to a support 1, and a second end 22 on which is disposed a connection means 5 designed to cooperate detachably with a connecting means 7 mounted around a filling orifice 49 of a dust bag 6.
  • the first end 21 of tube 4 advantageously comprises a flange 24.
  • the support 1 has an orifice 23 and is provided for connection substantially tight with the filling pipe 14.
  • the support 1 is constituted by a cardboard.
  • several types vacuum cleaners require to operate to detect the presence of the dust by the arrangement of a cardboard box.
  • the cardboard is mounted in the receptacle 13 so as to form a substantially sealed connection with the filling hose 14.
  • the vacuum cleaner does not need to cardboard to work.
  • the support 1 consists of an inner wall of receptacle 13 in which opens hole 23.
  • the filling pipe 14 is removable from the receptacle 13, such as shown in Figure 2. According to another embodiment shown in Figures 1 and 3 the filling pipe 14 is secured to the receptacle 13. The filler pipe 14 shown in Figure 1 is prominent inside the receptacle 13. The filling pipe 14 shown in Figure 3 opens simply in the wall of the receptacle 13, through the orifice 23.
  • the vacuum cleaner in which the invention is used can obviously include a support 1 consisting of a cardboard box and a filling 14 secured to receptacle 13, or a support 1 consisting of a inner wall of receptacle 13 and a removable filling pipe 14 from the receptacle 13.
  • a support 1 consisting of a cardboard box and a filling 14 secured to receptacle 13
  • a support 1 consisting of a inner wall of receptacle 13 and a removable filling pipe 14 from the receptacle 13.
  • the lengths and diameters of the filler pipe vary.
  • the connecting tube 4 and the dust bag 6 form a device for filtration according to the invention, adaptable to most types of vacuum cleaners.
  • the receptacle received the device filter according to the invention mounted on the cardboard forming the support 1, the cardboard having been taken from a filter recommended by the manufacturer of the vacuum cleaner.
  • this provision authorizes that be kept additional devices such as a non-return valve which would be fitted including the original cardboard.
  • the inventive cardboard dust filter therefore comprises the cardboard box 1 mounted on a connecting tube 4 by means 2, then a universal dust bag 6 by a connecting means 7.
  • the fixing means 3 is constituted by adhesive means, as shown in Figures 1 to 3.
  • the adhesive means is advantageously placed on the first end 21 of the tube 4.
  • the user thus has a connection tube ready for be mounted on the support 1.
  • the adhesive means consists of a ring double-sided adhesive well known in the trade.
  • the adhesive means consists of a layer of glue.
  • the fixing means is constituted by at least one suction cup.
  • the fixing means comprises mechanical elements such as clips or rivets passing through the collar 24 of the tube 4 as well as the support 1.
  • a seal disposed between the end 21 of the tube 4 and the support 1 guarantees the tightness of the assembly.
  • FIG 6 there is shown an embodiment of a bag dust used in the filtration device according to the invention.
  • the bag dust is made of a flexible textile material, such as a non-woven fabric and especially polypropylene.
  • the material is laminated in the form a sheet which is formed into a closed bag with an opening for filling.
  • the bag consists of the connection of two sheets 40 and 41 of the aforementioned material.
  • the leaves are shaped circular and their periphery constitutes an edge 42 or 43 which are secured by welding, especially by ultrasound, gluing or sewing in the edge areas 42 and 43.
  • One 40 of the two sheets has a filling orifice 49 to through which the dust-laden air, sucked in by the vacuum cleaner, passes through the bag with dust.
  • the connecting means 7 between the dust bag 6 and the connecting tube 4 is a connecting means disconnectable.
  • it is constituted by a ring 44 with thread "quarter-turn”, which cooperates with an external thread of the connecting tube 4, which forms the disconnectable connection means 5.
  • the removable connecting means 7 comprises an annular ring 44 whose internal bore 45 carries sectors of thread 46 and 47, so as to produce a "quarter-turn" nut.
  • the ring is intended to be welded, in particular by ultrasound, or glued around the orifice filling 49 in zone 48.
  • FIG. 7 there is shown another embodiment of a bag filter from the filtration device according to the invention.
  • the dust bag of FIG. 7 comprises sheets in the shape of a polygon, preferably a hexagon.
  • the filling orifice 50 can be offset from the center of the sheet.
  • the material comprises two or three layers.
  • the first layer arranged towards the outside of the bag, is made, as it already has been described in synthetic material, for example polypropylene.
  • the second layer is made of a fibrous material.
  • Layer external material is chosen so as to give solidity to the dust bag, flexibility so as to allow it, when vacuuming fill the entire vacuum container.
  • a third layer, internal is added to stop the coarsest dust and avoid rapid clogging of the inner layer.
  • the bag can be made from a single sheet whose edges are joined by a ring link.
  • the annular ring 44 can be produced directly on the periphery of the filling orifice by carrying out local hardening of the sheet of nonwoven fabric, by heating it locally and / or by bringing of the material.
  • the hexagonal shape of the leaves in Figure 7 helps minimize cutting losses when the sheets cut to make bags dust according to the invention is collected on one or two rollers. Indeed, cutting can be done edge to edge for most of the hexagons cut on a rectangular strip, except on the sides of the strip and on the opening cut.
  • the arrangement of the two sheets making up the bag dust cooperates with the flexibility of the nonwoven fabric, as well as with the revolution shape of the bag, so that the maximum volume available in the receptacle is anyway occupied by the bag when it fills.
  • connection means 7 is advantageously permanently attached to the dust bag 6 as explained with the aid of Figures 6 and 7.
  • FIG 4 there is shown a schematic sectional view of a first embodiment of the connecting tube 4.
  • the tube 4 has the shape a hollow cylinder, the end 22 of which having an orifice 15 is intended to come in connection with the filling opening of the dust bag.
  • the orifice of universal dust bag of the filtration device of the invention is still the even. Therefore, all the connection tubes of the replacement kits according to the invention have an end 22 intended to come into relation with the orifice dust bag of the same diameter.
  • the connecting tube is a model intended to "shrink" the diameter of the bag filling orifice, to adapt it to a smaller diameter filling pipe.
  • the end 21 comprising an orifice 16 is provided with an annular shoulder in the plane perpendicular to the axis of cylinder 4 so that the diameter inlet port 16 is smaller than the diameter of outlet port 15 towards the dust bag.
  • connection means 5 is for example formed by a thread made in the form of a helical groove on the external face of the end 22 of the connecting tube 4, designed to cooperate with the thread 45 of the ring 44.
  • FIG 5 there is shown another model of connecting tube in which the end 21, comprising an inlet orifice 17, intended to come in relation to the filling pipe 14, and in relation to the support 1, is of a larger diameter than that of the outlet orifice 15.
  • the tube of link 4 of Figure 5 is said "diameter enlarger". This can be caused in particular because the filling pipe 14 in the dust filter receptacle, inside the vacuum cleaner is of a diameter more important than that of the orifice 49 of the dust bag.
  • the lengths of the various filling pipes 14 can be adapted by tubes of link 4 of various lengths, and particularly, although this is not described here, by abutment of several connecting tubes.
  • the invention is used in the following manner.
  • the user discards the old dust filter without cardboard and presents the latter in front of the set of connection tubes of the kit mounting, to select the length and diameter suitable for the pipe filling 14 in the receptacle of the vacuum cleaner.
  • the suitable side of the cardboard which must receive the tube of bond is necessarily the one that carried the old dust bag of the filter original, because any cuts or asymmetries in the cardboard freeze its orientation.
  • the filtration device according to the invention can then be inserted into the vacuum cleaner receptacle which, again receiving a cardboard filter, can operate normally.
  • the user directly fixes the end 21 of the connecting tube 4 on the support 1 around the orifice 23 using the means of fixing 3.
  • the universal dust bag 6 being full of dust, it just buy a set of refills consisting of dust bags universal 6 fitting on the connecting tube 4.
  • the connecting tube 4 can remain permanently fixed to the support 1.
  • the connecting tube 4 is permanently mounted on support 1. The user no longer has need to disassemble said tube, since it suffices to replace bag 6, by example when the one is full, and not the universal filtration device.
  • Any vacuum cleaner equipped with a connection tube 4 from a kit universal for dust filter can use a universal dust bag 6.
  • the invention finds its application in the technical field of suction devices for cleaning.
