Definitions

  • the present invention relates to the field of vacuum cleaners of the canister or tank type, or more generally to any suction device intended for cleaning.
  • the present invention relates to special means for adapting a filter intended to collect dust on a vacuum cleaner.
  • vacuum cleaners which are equipped with a suction turbine, and with a hose equipped with a dust cleaning tool.
  • the vacuum cleaner hose is removable and has a tubular end which is adapted to connect to an opening of 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 to the dust filter.
  • the dust filter is, for example, constituted by a paper bag mounted on a flange of cardboard or cardboard and which the user inserts in the receptacle of the dust filter, in the vacuum cleaner.
  • the dust filter lets in the suction air from the turbine and has an orifice fitted with a flap to allow the dust sucked in from the cleaning tool to enter the paper bag and transferred through the vacuum cleaner hose. to the dust filter.
  • the paper bag When the paper bag is full, the user must remove it for disposal and replace it with an identical paper bag. Now, depending on the brand and of the model of the vacuum cleaner, the paper bags are different both in shape and in means of attachment to the vacuum cleaner itself.
  • the document FR-1 071 345 describes a vacuum cleaner comprising a filling hose and a housing for a dust bag.
  • the dust bag has a filling opening provided with a removable connection means to the filling pipe, such as a threaded ring secured to the bag around the filling opening.
  • vacuum cleaners Some models of vacuum cleaners are designed so that they only work if they recognize certain types of filters. This is particularly the case when the dust bag is mounted on a cardboard.
  • the vacuum cleaner may include a switch or an inhibiting device which prevents its operation (its start-up) as long as the cardboard box 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 embodiment offers the advantage of being able to use the dust bag with any type of vacuum cleaner, since it suffices to secure the bag on a cardboard suitable for the vacuum cleaner.
  • the object of the invention therefore aims to remedy the aforementioned drawbacks and to allow the user to overcome the dust filters 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 tube connection means allows the same connection tube to be reused with the bags used successively.
  • the fixing means makes it possible to secure the connecting tube to the support.
  • FIG. 1 represents a sectional view of part of a vacuum cleaner equipped with a filtration device according to the invention
  • FIG. 2 represents a sectional view of part of another vacuum cleaner equipped with a filtration device according to the invention
  • FIG. 3 represents a sectional view of part of another vacuum cleaner equipped with a filtration device according to the invention
  • FIG. 4 represents a first embodiment of a connecting tube according to the invention

  • FIG. 6 and 7 show two schematic perspective views of embodiments of a dust bag of a filtration device according to the invention.
  • FIG. 8 shows a schematic perspective view of a dust bag with cardboard according to the prior art.
  • the connecting tube 4 is intended to be used with a dust bag 6 to produce an adaptable universal filtration device in most vacuum cleaners.
  • a vacuum cleaner comprises a receptacle 13 designed to receive the dust bag 6 and a filling pipe 14, as shown in FIGS. 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 vary 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 loaded with dust collected by the vacuum cleaner brush, towards the dust bag 6.
  • FIG 8 there is shown the detached perspective view of a dust filter of the prior art comprising a bag 77 made of paper and one end 74 of which is glued to a cardboard 70 with a central hole 73.
  • the cardboard is generally made of a relatively flexible cardboard which is glued to a folded paper bag. The latter, by bonding to the area 75 around the filling orifice 76, represented between the contour in phantom 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 traditional dust filter.
  • the accessory according to the invention consists of a connecting tube 4 comprising a first end 21 capable of being joined in a substantially sealed manner by a means of attachment 3 to a support 1, and a second end 22 on which is disposed a means connection 5 provided for cooperating detachably with a connection means 7 mounted around a filling orifice 49 of a dust bag 6.
  • the first end 21 of the tube 4 advantageously comprises a flange 24.
  • the support 1 has an orifice 23 and is provided for a substantially sealed connection with the filling pipe 14. O 97/49325 PC17FR97 / 01152
  • the support 1 is constituted by a cardboard.
  • several types of vacuum cleaners require to function to detect the presence of the dust bag by the provision of a cardboard box.
  • the cardboard is mounted in the receptacle 13 so as to form a substantially sealed connection with the filling pipe 14.
  • the vacuum cleaner does not need a cardboard to operate.
  • the support 1 is constituted by an interior wall of the receptacle 13 into which the orifice 23 opens.
  • the filling pipe 14 is removable from the receptacle 13, as shown in FIG. 2. According to another embodiment shown in FIGS. 1 and 3, the filling pipe 14 is integral with the receptacle 13. The filling pipe 14 shown in the FIG. 1 is prominent inside the receptacle 13. The filling pipe 14 shown in FIG. 3 simply opens into the wall of the receptacle 13, through the orifice 23.
  • the vacuum cleaner in which the invention is used may obviously include a support 1 constituted by a cardboard box and a filling pipe 14 integral with the receptacle 13, or a support 1 constituted by an interior wall of the receptacle 13 and a filling pipe 14 removable from receptacle 13.
  • a support 1 constituted by a cardboard box and a filling pipe 14 integral with the receptacle 13
  • the lengths and diameters of the filling hose vary.
  • the connecting tube 4 and the dust bag 6 form a filtration device according to the invention, adaptable to most types of vacuum cleaners.
  • the receptacle received the filtration device 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 the keeping of additional devices such as a non-return valve which would be fitted in particular with the original cardboard.
  • the cardboard dust filter of the invention therefore comprises the cardboard box 1 mounted on a connecting tube 4 by a fixing means 2, then a universal dust bag 6 by a connecting means 7.
  • the fixing means 3 is constituted by an adhesive means, as shown in FIGS. 1 to 3.
  • the adhesive means is advantageously disposed on the first end 21 of the tube 4.
  • the user thus has a connecting tube ready to be mounted on the support 1.
  • the adhesive means consists of a double-sided adhesive ring well known in the trade.
  • the double-sided adhesive ring has a first layer of glue, used to glue the ring initially on the first end 21 of the connecting tube 4.
  • the ring then has an annular support made of microporous foam, serving on the one hand of support for the layers of adhesive glues, and on the other hand, making it possible to make up for the irregularities of the surface on which the connecting tube will be glued.
  • the ring comprises a second layer of adhesive, protected by a film peelable by the user, and intended to come to permanently secure the connecting tube 4 with the suitable face of the cardboard or the support 1.
  • the ring double-sided adhesive must in fact be constituted in such a way as to: 1) resist the tensile and / or shearing force applied when the connection tube is connected to the bag;
  • the adhesive means consists of a layer of adhesive.
  • the fixing means consists of at least one suction cup.
  • the fixing means comprises mechanical elements such as staples or rivets passing through the flange 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 dust bag used in the filtration device according to the invention.
  • the dust bag is made of a flexible textile material, such as a non-woven fabric and in particular polypropylene.
  • the material is laminated in the form of a sheet which is shaped into a closed bag with a filling opening.
  • the bag consists of the joining of two sheets 40 and 41 of the aforementioned material.
  • the sheets are circular in shape and their periphery constitutes an edge 42 or 43 which are joined by welding, in particular by ultrasound, gluing or sewing in the edge areas.
  • One 40 of the two sheets has a filling orifice 49 through which the dust-laden air, sucked in by the vacuum cleaner, passes through the dust bag.
  • connection means 7 between the dust bag 6 and the connection tube 4 is a disconnectable connection means.
  • 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 connection means 7 comprises an annular ring 44 whose internal bore 45 carries thread sectors 46 and 47, so as to produce a "quarter-turn" nut.
  • the ring is intended to be welded, in particular by ultrasound, or bonded around the filling orifice 49 in the zone 48.
  • FIG. 7 there is shown another embodiment of a dust bag of 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.
  • two sheets are glued edge to edge along the straight edges like the edge 51, as described for the zones 42 and 43 of the bag of FIG. 6.
  • the material comprises two or three layers.
  • the first layer disposed towards the outside of the bag, is made, as already described, of synthetic material, for example polypropylene.
  • the second layer is made of a fibrous material.
  • the outer layer of synthetic material is chosen so as to give solidity to the dust bag, flexibility so as to allow it, during suction, to fill the entire receptacle of the vacuum cleaner.
  • a third, internal layer is added to stop the coarsest dust and avoid rapid clogging of the internal 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 locally hardening the sheet of nonwoven fabric, by heating it locally and / or by adding material.
  • the hexagonal shape of the sheets in FIG. 7 makes it possible to minimize cutting losses when the sheets cut to produce dust bags according to the invention are taken from one or two rollers. Indeed, the cutting can be done edge to edge for the majority of the hexagons cut on a rectangular strip, except on the sides of the strip and on the cut out orifice.
  • the arrangement of the joining of the two sheets constituting the dust bag cooperates with the flexibility of the nonwoven fabric, as well as with the shape of revolution of the bag, so that the maximum of the volume available in the receptacle is in any case occupied by the bag when it fills.
  • This avoids a disadvantage of folded paper bags which must have a geometry strictly calculated to adapt to the shape of the receptacle 13 of the vacuum cleaner to which they are dedicated.
  • connection means 7 is advantageously permanently secured to the dust bag 6 as has been explained with the aid of FIGS. 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 of a hollow cylinder whose end 22 having an orifice 15 is intended to come in connection with the filling opening of the dust bag.
  • the opening of the universal dust bag of the filtration device of the invention is always the same. Therefore, all the connecting tubes of the replacement kits according to the invention have an end 22 intended to come into contact with the orifice of the dust bag of the same diameter.
  • the connecting tube is of a model intended to "shrink" the diameter of the bag filling orifice, to adapt it to a filling tube of smaller diameter.
  • the end 21 comprising an orifice 16 is provided with an annular shoulder in the plane perpendicular to the axis of the cylinder 4 so that the diameter of the inlet through the orifice 16 is smaller than the diameter of the outlet orifice 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, intended to cooperate with the thread 45 of the ring 44.
  • FIG. 5 another model of connection tube has been shown in which the end 21, comprising an inlet orifice 17, intended to come into relation with the filling pipe 14, and in relation to the support 1, is of a larger diameter than that of the outlet orifice 15.
  • the connecting tube 4 of FIG. 5 is said to be "diameter enlarger". This situation can be caused in particular because the filling pipe 14 in the receptacle of the dust filter, inside the vacuum cleaner is of a larger diameter than that of the orifice 49 of the dust bag.
  • the tube 4 is advantageously constituted by two cylindrical sections:
  • the first cylindrical section linked to the inlet orifice 17, has a ring-shaped shoulder which borders the orifice 17, so that the connecting tube 4 can adapt to cardboard boxes whose orifice is of large diameter;
  • the second cylindrical section linked to the outlet orifice 15 always has the same diameter regardless of the vacuum cleaner or the box considered.
  • connection tubes 4 of various lengths, and in particular, although this is not described here, by abutment of several tubes link.
  • the invention is used in the following manner.
  • a universal mounting kit for a dust filter according to the invention which mainly comprises a plurality of connecting tubes.
  • the user throws away the old dust filter without his cardboard box and presents the latter in front of the set of connecting tubes of the mounting kit, to select the one of length and diameter adapted to the filling pipe 14 in the receptacle of the vacuum cleaner.
  • the suitable face of the cardboard which must receive the connecting tube is necessarily that which carried the old dust bag of the original filter, because the possible cuts or asymmetries of the cardboard freeze its orientation.
  • the filtration device according to the invention can then be inserted into the receptacle of the vacuum cleaner which, once again receiving a cardboard filter, can operate normally.
  • the user fixes the end 21 of the connecting tube 4 directly on the support 1 around orifice 23 using the fixing means 3.
  • the universal dust bag 6 being full of dust, it will suffice to buy a set of refills consisting of universal dust bags 6 which are mounted on the connecting tube 4.
  • the connecting tube 4 can remain permanently fixed on the support 1.
  • the connecting tube 4 is permanently mounted on the support 1. The user no longer needs to dismantle said tube, since it suffices to replace the bag 6, for example when the one is full , not the universal filtration device.
  • Any vacuum cleaner fitted with a connection tube 4 from a universal dust filter kit can use a universal dust bag 6.
  • the invention finds its application in the technical field of suction devices intended for cleaning.
