TECHNICAL FIELD

TECHNICAL LEVEL

A number of chimney cleaners have been patented worldwide. The first wave of mass patenting of such devices took place between 1905 and 1915. At that time chimney sweeping was considered to be a very important and popular job because very many people lived in separate homes and professional chimney sweeping services were very popular. At that time, a variety of chimney cleaners were patented, mainly for professional chimney sweeps. The second wave of patenting of such devices, though much weaker than the first wave, was in 1935-1940. Third (even weaker) - 1970-1980. And in the last 20-30 years, the patenting of chimney cleaners has slowed down considerably, to a lesser extent.

U.S. Pat. US973911, published 1910 October 25 This patent provides an elementary set of brushes for cleaning chimney walls. Part of the brushes in this kit are for cleaning vertical walls, some for horizontal (bottom). In order to clean the walls at the bottom of the chimney, said brushes are attached to long rod-type holders. However, these types of brushes require the appropriate skills (a professional is needed), the chimney walls can only be cleaned from the top (which means climbing on the roof) and quickly get dirty.

Also known is U.S. Pat. US764265, published 1904. July 5 This patent discloses a chimney cleaning structure that is lowered into the chimney from above using a well-type lowering / lifting mechanism. The base of the chimney cleaning structure consists of hooks attached to the sides of the lowered structure, which clean the inside of the chimney during lifting of the structure. The structure itself descends due to its weight, while it rises due to the well-type lift mechanism. This design has many serious drawbacks: it is very clumsy, it hooks the chimney walls, is only suitable for tall straight chimneys, and is intended for professional use only.

Also known is U.S. Pat. US730359, published 1903. June 9 This patent describes a hand-held umbrella-shaped spring structure consisting of cleaning hooks which, depending on the tension condition of the controlled spring, may expand more or less. However, such a chimney cleaning design is suitable for cleaning straight chimneys with a small depth perimeter. This design also features a spring mechanism which is sensitive and deteriorates when dirt enters its internal structure.

Also known is U.S. Pat. US966853, published 1910; August 9 This patent describes a flush-down panel with sharp protrusions attached to its edges, which also serve to clean the chimney walls. The structure is lowered using a heavy weight attached to the underside of said plate. The whole mechanism is very complex and cumbersome, has many fittings and is adapted to the inside perimeter of a very specific stack.

Closest to the state of the art is American patent no. US1964057, published April 1934. June 26 This patent describes a fairly simple chimney cleaning system that can clean chimneys of virtually any geometry. This system consists of a cleaning brush (the shape of the brush itself is very similar to that of a bottle cleaning brush), which is inserted into and removed from the chimney opening using a wire of sufficient diameter. The brush is made of metal or a very strong material that will not bend when cleaning the chimney walls. On the one hand, said cable is secured with a brush and, on the other, with a drum-shaped holder which adjusts the length of the cable. Such a mechanism allows cleaning irregularly shaped chimneys not only from above but also from below. However, this type of purifier is not very efficient as the purge only takes place in the vertical direction. Also, the structure itself is not comfortable as the brush has to be manually and mechanically moved at all times, which requires a lot of physical force.

An overview of the entire patenting history of chimney cleaning systems shows that most such systems are cumbersome and focused only on the professional user.

THE SUBSTANCE OF THE INVENTION

The object of the present invention is to provide a chimney wall cleaning device having the following features:

the chimney could be cleaned from below (not only from above);

cleaning procedure suitable for metal, brick, chimneys of any diameter, length and shape;

the chimney walls are cleaned but not scratched during the cleaning procedure;

the structure is easy to operate, high in power and requires minimal physical effort;

the construction is reliable and lightweight;

more focused not on the chimney sweep - the professional, but on the common man.

An essential feature of the present invention is that:

a brush for cleaning the chimney wall is rotated about its axis (like a propeller) and wipes the chimney wall in a horizontal direction;

said brush having twisted rectangular rope nylon bristles which, in rotational (working) mode of the brush, removes (removes) even the slightest amount of dirt from the walls of the chimney (internal);

said brush being rotated by a rotating mechanism (e.g., a drill having a connecting member inserted into its head) which is connected to the brush through the composite shaft members.

Such a chimney sweep allows for quick (easy assembly and disassembly) and reliable (due to its simple construction and few components) very clean chimney of any type, diameter and shape. Such a purifier does not require a lot of physical effort (can be used by both men and women) and is aimed at the average user (not the professional). Therefore, this efficient, powerful and at the same time simple and reliable tool is the dream of every person with any type of chimney. And the very use of this tool is safe and reliable because it can be used day or night, in any weather, even by people with disabilities who can't climb on the roof, or when it is not safe due to environmental conditions (bad weather, night, etc.).

PREFERRED EMBODIMENTS

The biggest danger to people and home safety is the release of combustion products - soot and creosote - that settle on the chimney walls during the fuel combustion process. These are extremely flammable substances whose accumulation in the chimney can cause fire. The particles of these materials are sticky. Exposed to high temperatures, humidity and draft in the chimney, they adhere to the chimney walls. In this way, the chimney creates and builds up plaque (resin), which not only reduces the permeability of the chimney, but also poses a fire hazard. In addition, reduced throughput reduces the efficiency of the heating appliance (eg fireplace, stove, etc.) and accelerates wear. Therefore, the chimney of the heating device used must be regularly maintained and periodically cleaned. In addition to daily chemicals and fuel additives, mechanical chimney cleaning - brushing with plaque removal - is also required. Brushing a chimney is usually a difficult and tedious job that requires time, patience and knowledge. As a result, only professional chimney sweeps have been able to perform it successfully for a long time.

The present invention provides a rotary chimney cleaning device / construction which has many useful features and substantially simplifies the chimney cleaning procedure.

FIG. 1 shows a general construction of a stack cleaning device (1). It consists of the following parts: the brush (2), the composite handle elements (3) and the rotation mechanism (4). One end of the composite shaft members (3) is fixed (secured) to the brush (2) and the other end to the torsion mechanism (4). The amount of composite shaft members (3) determines the distance between the brush (2) and the rotation mechanism (4), i.e. the deeper the brush (2) is to be inserted into the chimney opening, the more composite stem elements (3) must be joined. When all three parts of the structure (2, 3 and 4) are connected to each other, the torque is transmitted to the composite shaft members (3) and the brush (2) when the rotation mechanism (4) is actuated. The brush (2) is inserted into the opening of the chimney and, as it rotates, the cleaning process of the chimney walls begins.

With such a rotary chimney sweeper, there is no need to climb the roof: ladders and other tools are not required. Chimney of any length can be easily cleaned from below by inserting a brush (2) into the chimney through the opening of the heating device. The above-mentioned rotary chimney sweeper (1) requires no special knowledge, no great physical effort (can be easily cleaned by men as well as women) or a plethora of cleaning agents. With its simple control, this unit (1) can clean the chimney reliably, quickly and easily, save money and, most importantly, always know that the chimney is in good working order and will not cause a fire.

FIG. 2 shows a close-up of the rotation mechanism (4) as well as its attachment (locking) to the composite stem element (3). The function of the rotation mechanism (4) can be perfectly performed by a (simple) drill having a transition element / transition (6) mounted on the head (5) for connecting the drill (4) to the nearest (first) composite stem element (3) 7). Laboratory studies have shown that the use of a drill in the scheme (1) of the present invention is very suitable. Using the drill (4) allows the machine (1) to operate long and reliably.

FIG. 3 is a close-up view of the connection of the stem components. The rod components are connected to one another using a joint (7).

FIG. 4 is a close-up sectional view of the brush (2). This brush (2) is rotary because it also rotates about its axis when it is actuated by the rotation mechanism (4). Depending on the power of the drill, the brush (2) rotates from a few hundred to several thousand times per minute. The chimney cleaning device (1) of the present invention is characterized by high power and a tremendous cleaning power combined with a drill. Said brush (2) consists of bristles (8), bristle holder (9) and bristle attachment units (10). The brush (2) bristles (8) and the composite stem members (3) are made of nylon, an extremely strong, resilient, abrasion and chemical resistant material. The nylon gives the brush (2) the bristles (8) strength and durability, while the composite stem members provide extreme flexibility, allowing for easy cornering of all chimney turns and reaching the top of the chimney, i.e. such a device (1) is suitable for chimneys of any diameter, length and shape. The bristles (8) of the brush (2) have a special shape - twisted quadrilateral. In shape they resemble long thin drills. Enormous drill forces are screwed in, cutting and scraping to remove plaque of any strength. Furthermore, the nylon brush (2) of the present invention is superior to a conventional metal brush in that it does not scratch the chimney walls and is suitable for any type of chimney, both metal and brick.

FIG. 5 is an illustration showing how the stack cleaning device (1) of the present invention cleans the stack walls. The entire construction of this unit (1) is easy to assemble and disassemble. Laboratory tests and measurements have shown that the optimum brush (2) diameter is 45 cm and the flexible composite shaft elements (3) - 1 m. However, the dimensions may be different.

In order to illustrate and describe the present invention, descriptions of preferred embodiments are set forth above.
