Definitions
- the present invention relates to a device for cleaning air ducts, comprising a head intended to be introduced into the duct to be cleaned and kept connected by means of a supply hose to a pressurized air generator; said head being provided with an anterior part with shock absorbing means and with a subsequent part coupled with the previous one and provided with pressurized air outlets composed of flexible hoses that describe changing movements during the exit of said pressurized air, which significantly improves the effective cleaning of the inner surface of the duct, including recesses, corners and built areas with difficult access.
- European Patent E90850157 contemplates the generation of an important vacuum inside the conduit to be cleaned, using the flow of air originated to move inside the conduit a cleaning element that can be a brush.
- Patent E91905065 contemplates the use of a cleaning device connected by a supply hose with a source of pressurized air, said device defining an annular groove through which the pressurized air in charge of cleaning the duct is projected, causing Simultaneously, reaction forces are used to move the device inside the conduction in question. -two-
- Patent E91917477 also contemplates a cleaning means connected by means of a conduit with a source of pressurized air, said means defining one or more openings in the form of nozzles directed backwards;
- the cleaning means have a nozzle in the form of an annular groove through which the pressurized air is discharged to clean the conduit walls.
- WO 9324246 contemplates, as in the previous two, a duct that relates a source of pressurized air with a spherical body provided with outlets of said pressurized air oriented towards the rear area, so that they simultaneously produce the cleaning of the duct and the advancement of the mentioned body.
- the mentioned devices therefore contemplate a cleaning element that is connected by means of a supply hose to a source of pressurized air, said cleaning element having pressurized air outlets, which simultaneously provide the cleaning of the duct and the advance of that element.
- the diameter, the section, or the ascending or descending or zigzag path of the conduit are characteristics that separately or in some grouping prevent one or another type of these current cleaning means, resulting in the availability of several of they must be left unclean sections.
- the device object of the invention comprises a head intended to be introduced inside the conduit to be cleaned and which is connected by means of a supply hose to a pressurized air generator.
- Said head comprises two pieces, one front and one rear, which are held together by means of a thread, a plurality of flexible hoses being connected to the rear piece through which all or part of the pressurized air emerges.
- the front part consists of a hard and soft body of low density and diameter that is the largest of all the head components, in order to cushion the possible impacts of the head against the walls of the duct, preventing them from being damaged both said walls and the head itself.
- the thread that attaches the front piece to the rear can be screw type with nut, in which case the soft body and the hard body are pierced so that the screw passes through the hole to the rear piece, which itself carries the nut female
- the screw and its ring are loose pieces, or it can be defined on the back of the front piece and finish in a cavity coinciding with the front surface of the rear piece.
- the coupling of the two main parts, until now called front and rear, is such that the distance between them is adjustable, so that if they come together completely, all the pressurized air has to leave through the hoses, but that if leave a distance, regulated by unscrewing the front part if it is unscrewable or by the construction provided in the hard body of the front part when the union between both main parts is by screw and nut, the pressurized air will also leave through this circular groove .
- the curtain of air that forms the one that leaves through this circular groove means that the hoses, in their chaotic movement, will never be placed in front of the head since they will not be able to cross such a curtain, and that according to -4- what types of cleaning is an additional advantage.
- the pressurized air enters the set of the two pieces through the rear piece, which presents at its rear end a tubular appendage for the connection of the hose associated with the pressurized air generator.
- the inner hole of the tubular appendage extends to the anterior surface of said posterior piece, from there it is distributed to be ejected through the hoses or through the slot that is left between the two main pieces.
- This rear part also has in its front part a plurality of holes extending to the rear surface of said part; The soft and flexible hoses are attached to these holes, which are thus oriented towards the rear area of the head.
- the rear part (4) is coupled to the hose (3) by means of a tubular appendix (41) whose inner hole extends to the holes (54), which flow into the cavity (43), from which the pressurized air will exit to the conduit through the groove (7) and through the hoses 6.
- the front part 5 is coupled to the rear 4 by means of a screw (63), with a ring (62), which enters the female (42), or because it has a threaded portion (42) to enter said female (42) .
- the piece (4) also has holes (44) that start from the cavity (43).
- the hoses 6 are connected to these holes (44) by flaking one of its ends, passing the hose through the hole, and letting the flared extension (72) make -7- of a self-regulated stop precisely because of the air pressure, or they are connected by means of the so-called pneumatic hose quick connection, which provides a clamping of the tube by pinzamineto of the same.
- the soft body (51) has the mission of cushioning the possible impacts of the head (1) against the walls of the duct (2) during its cleaning.
- annular groove (7) forming an additional outlet of pressurized air will be defined between them.
- the width of the annular groove (7), defined between the frustoconical surfaces (45 and 55), is regulated by threading to a greater or lesser extent of the pieces (4 and 5) if there is an appendix (52), or changing the hard body (8) for another whose teeth (82) have different height.
- the annular groove (7) is regulated, since variations in the proportion of pressurized air coming out of the hoses (6) and the groove (7) grant displacement, wobble behaviors , or whip markedly different to the head and its hoses.
- the air curtain (9) will prevent the hoses from getting ahead of the head.
