Description

VACUUM CLEANER CLEANING BODY
DESCRIPTION
Field of the Invention
The present invention relates to vacuum cleaners and the method ofcleaning the fluid path.
Background to the Invention
Vacuum cleaners are typically used for domestic and industrial cleaning of dirt. Solid and/or liquid dirt is aspirated by the vacuum cleaner such that the dirt is communicated via a fluid path from a conduit to a material collection chamber. The vacuum cleaner comprises of a conduit, which includes all parts the dirt travels through before collection in the material collection chamber and the vacuum housing, which contains the motor, filters), electrics and material collection chamber. If the dirt is wet and/or is fine (for example dry wall material or dust from a sander) or is hazardous (for example bodily fluid or asbestos), dirt residue may remain: in the conduit; on the distal end of the conduit and on the exterior surface of the conduit and vacuum housing resulting in bacterial growth, odour problems and environmental health risks.
Use of a disposable material collection chamber and isolating the vacuum housing from the dirty area limits contamination, but leaves the conduit both inside and out, requiring cleaning which is dirty, unhygienic and potentially dangerous to a user.
Pipeline pigging uses the pressure driven flow of fluid in a pipeline to push a Pig along a pipeline to inspect, clean orclearthe inside.
There are several patents covering differing aspects of pipeline pigging: GB1083797 discloses a hollow sphere for use in a pipeline; US3543324 (A) discloses a Pig ball that cleans inside a pipeline and GB1230129 discloses a sphere with protuberances. PIGs perform cleaning operations only on the internal surface of a pipeline and are removed after use.
Example embodiments of the present invention provide a practical, very low cost thorough and safe solution to a potentially dangerous problem by adapting a Pig to clean the exterior surface, interior surface and distal end of the conduit of a vacuum cleaner.

Description of Example Embodiments
With reference to the drawings, similar reference numerals denote corresponding features unless described otherwise.
Figure 1 shows a perspective view of a cleaning body 1, comprising of a resiliently deformable material in a bullet shape with one hole 2 therethrough perpendicular to the length of the body.
Figure 2 shows a perspective view of the cleaning body 1 (shown in Figure 1) removably coupled to the conduit 3 of the vacuum cleaner by insertion of the conduit 3 into the hole 2 in the cleaning body. The resiliently deformable, elastomeric properties of the cleaning body allow the hole to expand to a diameter that the conduit is comfortably inserted and pushed through, yet still provides sufficient resistance between the surface of the hole and the outside surface of the conduit to facilitate cleaning.
Figure 3 shows a perspective view of the vacuum cleaner with the cleaning body 1 removably coupled to the exterior surface of the proximal end 5 of the conduit 3 ready to commence cleaning of the conduit 3 and distal end 4. Impermeable sheet material 6 is removable coupled to conduit 3 with vacuum housing 7 located on the clean side of the vacuuming process.
Figure 4 shows a perspective view of a vacuum cleaner with the cleaner body 1, impregnated with disinfectant pushed by a member 8 moving from proximal end 5 towards distal end 4, in use cleaning the exterior surface of the conduit 3. Impermeable sheet material 6 is removable coupled to conduit 3 with vacuum housing 7 located on the clean side of the vacuuming process.
Figure 5 shows a cross sectional view of the cleaning body 1 with the interior surface of the hole 2 in contact with the exterior of the conduit 3 and the distal end 4. It demonstrates how the resiliently deformable material and elastomeric properties of the cleaning body 1 expand back into shape and therein constrict around and clean the distal end 4 as the cleaning body uncouples from the conduit.
Figure 6 shows a perspective view of the cleaning body 1 and the conduit 3, whereby the distal end 4 of the conduit 3 is aligned with the circular cross section of the cleaning body 1 ready for the cleaning body to be vacuumed into the conduit 3. The cross-sectional circular diameter of the bullet shaped body is larger than the internal diameter of the conduit and it is the resiliently deformable, elastomeric properties of the cleaning body 1 which allow the body to compress as it is vacuumed into the conduit, facilitating easy travel through the length of the conduit 3 whilst still providing sufficient resistance, with sufficient contact between the surface of the body and inside surface of the conduit, to facilitate cleaning.
Figure 7 shows a perspective view of the cleaning body 1 and the conduit 3, where the cleaning body 1 is partially vacuumed into the conduit 3 and it shows how the resiliently deformable material of the cleaning body 1 compresses into and thereby cleans the opening of the distal end 4.
Figure 8 shows a perspective view of the cleaning body 1 and the conduit 3, where the cleaning body 1 is partially vacuumed into the conduit 3 and it shows how the resiliently deformable material of the cleaning body 1 has compressed into the opening of the distal end 4, further cleaning the distal end 4 and thereby the exterior surface of the cleaner body 1 is now in contact with and cleaning the interior surface of the conduit 3 (not shown).
Figure 9 shows a cross sectional view of the vacuum cleaner with cleaning body 1 in the conduit 3 being vacuumed from distal end 4 towards proximal end 5 for deposit into the material collection chamber 9 contained within vacuum housing 7, where the exterior surface of the cleaner body 1 is now in contact with and cleaning the interior surface of the conduit 3. It further shows resiliently deformable material ofcleaning body 1 adapts to the changing shape of conduit 3.
Figure 10 shows a perspective view of a vacuum cleaner with a vacuum cleaner housing 7 mounted on wheels 10 and an anchored impermeable sheet material 6 removable coupled to conduit 3. The cleaning body 1, impregnated with disinfectant is moved along the external surface of the conduit 3 from the proximal end 5 towards the distal end 4 by pulling conduit 3 from the proximal end 5, wherein the impermeable sheet material 6 provides a barrier between any remaining dirty area and the clean exterior conduit and vacuum housing 7. As the cleaning body 1 uncouples prior to the impermeable sheet material reaching the end of distal end 4, the cleaning boding 1 can be vacuumed into conduit 3 whilst the impermeable sheet material 6 is still coupled to distal end 4 (not shown).
Figure 11 shows a method of using a cleaner body with a vacuum cleaner according to an example embodiment.
As set out above, a cleaning body according to the example embodiments provide a low cost thorough and safe system that cleans wet and/or dry dirt from the conduit of a vacuum cleaner.
The cleaning body in use with the impermeable sheet material provides complete cleaning of the conduit of the vacuum cleaner and isolation of the vacuum cleaner housing and cleaned exterior conduit from any contamination.
Furthermore, the use of the cleaning body; the impermeable sheet material and a disposable material collection chamber (with/without built-in filter) provides a complete end to end coverage for both the fluid path and the spray that may externally contaminate the vacuum cleaner.
The components of the system are low cost and easy to deploy. Usability of the system is enhanced by making use of existing arrangements and a recognisable structure thatare familiarto the user.
The features described herein are suitable for inclusion with a vacuum cleaner at time of first manufacture or can be used with existing vacuum cleaners as appropriate.
Although a few preferred embodiments have been described and shown, it will be appreciated by those skilled in the art that various modifications and changes might be made without departing from the scope of the invention as defined in any appended claims.
