Description

TITLE VACUUM CLEANER BRUSH WITH SELF-POWERED UVC LAMP
DESCRIPTION
Object of the-present patent is a brush for vacuum cleaner with integrated UV-C (germicide) lamp, that can work without being connected to an external electric power supply, because the current generator, necessary for its powering, is part of the product itself.
The present patent is applied to the field of vacuum cleaners and relevant accessories. Due to its construction peculiarities, which will be described afterwards, it can be also applied to steam cleaners and cleaning appliance fields.
Several kinds of brushes are known among vacuum cleaners accessories, used for different purposes: floor and parquet brushes; carpet and sofas brushes; this patent refers to this kind of accessories. Constructive methods of brushes present in the market, divided into floor and/or parquet brushes, intended to vacuum on hard and regular surfaces, and brushes for soft and irregular surfaces, such as carpets, sofas and fitted carpets.
This last kind ofbrushes has additionally a roller, with some bristles shrunk-on. This roller, when rotating, moves the dirt which is nested into the fabric, and facilitates its suction through the slit which is under the brush.
The roller can operate through an electric ratio-motor or an air operating motor.
Brushes that are present in the market can suck the dirt from a surface but cannot "disinfect" it. For this reason, in the, last years, we have seen new appliances in the market that have this "disinfection" function; this kind of appliances utilize detergents or water steam at high temperature.
Recently new products, named "sweeper", have been put in the market; they combine UVC lamps with rotating carpet brushes (see patent applications JP2005124861 A2 - EP 1714601 A2 - WO2006/015390 A2) The germicide lamps (UVC) give out a light with a wave length of 253,70 nm named "germicide" for its capability to neutralize bacteria. As a matter of fact the exposure of these bacteria colonies to the ultra violet OVC radiation neutralizes their effect. These new products overcome the limit of normal vacuum cleaners" brushes and thus they ''disinfect'" as well. These "sweepers'" anyway show some limits, first of all the powering of lamps by using rechargeable batteries. This kind of powering presents some inconvenience for the final user who lias to remember to charge the battery; electricity consumption due to everlasting charges and not last the chemical limit of rechargeable batteries, in fact, continual charges and discharges damage these batteries that need then to be substituted with all ecological problems linked to their disposal and their high cost. Electrical powering of the lamp can be done also through the electrical power supply of the vacuum cleaner, and this can solve the problems created by batteries. This requires a more complicated construction, in fact the power supply must pass through the flexible suction hoses, and to do this a particular and expensive execution of these hoses is needed: they have to be co-extruded and cables have to pass well separated from the suction channel. In particular, for wet & dry appliances or steam generators, the execution of these brushes needs a high grade of protection from humidity thus requiring considerable and complicated project for its construction.
The aim of this patent is to solve the described problems, i.e. to create a kind of brushes equipped with this "disinfection" system through UVC lamps, combined to a self-powering system with no need of batteries or external electrical power supply.
The product is then universal and suitable for any vacuum cleaner on the market because it does not need any adaptation or interface of the appliance.
This result is entirely and fully performed by the invention which is the object of the present patent, and realized as follows.
The air sucked by the motor fan inside the vacuum cleaner, connected to the brush through the pipe union (4), enters the brush through the suction inlet (5). Through the internal structure of the brush the air is conveyed to the fan (2) that, due to this forced air flow rotates at high speed, and then goes out of the pipe union-towards the appliance. Approximate but not mandatory rotation speed of this fan (2) is about 2000- 2500 rounds per minute. The fan (2) is connected, through a timing belt (7). to a synchronous motor or a dynamo (8), that, rotating, creates electi ic current at a certain voltage. This current is than transformed by an electronic board (6) and thus used to switch on the UVC lamp (3) and keep it lighted. A switch (9) is connected in series between the motor/dynamo (8) and the electronic board (6), that is used to interrupt the load generated by the motor (8) and allow, in particular applications if needed, the connection of the fan (2). through another belt (10), also to a rotating brush (1) for the carpet cleaner function.
