DESCRIPTION of the Invention with TITLE:

"BLOW RODS for cleaning flues"

According to my information, there are few systems on the market for cleaning flues, such as manual brushes (which can only cover semi-straight sections of flue or at most a curve) or a system of rotating brush and probe operated by a drill (which has the drawback of having to disassemble part of the flue in order to assemble it). None of these tools is equipped with a system with a sling for connection to the inspection cap, for the insertion of the probe and the aspirator (Table 3).

“SOFFIA CANNE” is a compressed air and suction system for cleaning flues, designed for pellet stoves.

It is equipped with a special head with rotating blower (Table 1 - Figure C) which is manually inserted into the flue pipes by means of a probe (Table 3), the cleaning of the internal surfaces takes place with the compressed air coming out of the blower rotating (through 4 holes ø 1.2 mm.) against the internal wall of the flue, favoring the detachment of soot (Table 4 - Figure A).

This head is mounted on a probe made with plastic and flexible piping (Table 1 - Figure A) which allows it to be inserted inside even very long flues and to overcome several curves.

Thanks to the help of a small compressor and a simple ash vacuum cleaner, which are connected, through a kit (Table 2), to a single inspection point on the back of the stove, the cleaning of the flue can be done in a very short time. without disassembling pieces, without dirtying anything and without having to climb onto the roof (see example Table 3).

The kit consists of:

1) Head made with steel wire arches with a diameter of 2 mm. (Table 1 - Figure C) assembled to a rotating blower (Table 1 - Figure D) and connected to a brass directional joint (Table 1 - Figure B) and to the probe (Table 1 - Figure A) by means of quick couplings. The blower, which rotates on a bearing ø 8-22, has a casing and a copper or steel nozzle (Table 4 - Figure B).

2) Fitting for connection to the inspection socket of the flue, made of polyethylene or other plastic material, with a conical base for insertion into the flue, sling for the connection of the ash vacuum cleaner and for the entrance of the rotating head and of the probe, soot cap and straps for fixing to the Inspection socket (Table 2 - Figure À). <™>

3) Probe consisting of a suitable pipe in flexible plastic material with a diameter of 15 mm. and with a thickness of 2 mm., length m. 10 - 15 - 20 (Table 1 - Figure A).

4) Compressor weighing 5.6 Kg with air intake 180 It./min., Available on the market.

5) Ash vacuum cleaner type, weighing 4.3 kg, with squotifilter, available on the market.

The complete kit with aspirator and compressor weighs approximately 12.5 kg and is therefore easily transportable.

This system facilitates the user who has a saving on maintenance of almost 50% and encourages the trade of pellet stoves, since maintenance costs are lower.
