DETAIL DESCRIPTIONS OF THE INVENTION

(8) All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

(9) The present invention generally relates to cleaning tools and accessories for the bathroom. In particular, the present invention is an alternative design for a toilet brush that is compact and self-cleaning. Many traditional toilet brushes have bristles that soak in contaminated water after each use, leading to mold growth and general unsanitary conditions. Additionally, traditional toilet brushes are stored in tubular receptacles that, if not regularly cleaned, collect a great amounts of bacteria as contaminated water builds up within the receptacle. Another common problem is that the existing toilet brushes are easily accessible to pets, thus exposing pets to contaminated brush heads. The present invention is a retractable toilet brush that is self-cleaning and does not require a separate holding container. These features prevent mold and bacteria growth, leading to more sanitary conditions within the bathroom.

(10) Referring to FIG. 1 through FIG. 3, the present invention comprises a handle 1, a connecting shaft 2, a tubular enclosure 3, a removable brush 6, a plurality of ultraviolet (UV) light sources 9, and a battery 10. The handle 1 acts as the gripping element and allows a user to easily handle and manipulate the present invention. The handle 1 is terminally connected to the connecting shaft 2. Additionally, the handle 1 is preferably composed of water-resistant rubber material and may contain a multitude of ridges in order to conform to the contours of the human hand. The connecting shaft 2 connects the handle 1 to the removable brush 6 and is preferably an elongated tube that is composed of high quality stainless steel in order to withstand vigorous use. This positions the removable brush 6 at a significant distance from the handle 1 in order to allow the user to safely reach/clean the lower most portions of the toilet bowl. The removable brush 6 provides the scrubbing action in order to engage and subsequently clean contaminated surfaces of the toilet, in particular the inside surfaces of the toilet bowl. The removable brush 6 comprises a central rod 7 and a plurality of bristles 8. The removable brush 6 is attached to the connecting shaft 2 by the central rod 7. More specifically, the central rod 7 is threadly engaged to the connecting shaft 2 in order to allow for easy removal and replacement of the removable brush 6. A male-female threaded connection between the central rod 7 and the connecting shaft 2 ensures a secure attachment while simultaneously allowing for easy removal. Alternative attachment means may be used to attach the central rod 7 to the connecting shaft 2 as well.

(11) The plurality of bristles 8 is distributed along the central rod 7 and is the component which directly engages with the contaminated surface in order to physically scrub and dislodge contaminated matter, such as human excrements. The plurality of bristles 8 is radially connected around the central rod 7 to yield an elongated cylindrical shape and increase the surface affected by the present invention. Referring to FIG. 4, the plurality of bristles 8 also prevents and or inhibits the growth of mold and bacteria through a hygienic coating 16, wherein the hygienic coating 16 contains hydrophobic properties and anti-microbial properties. In particular, each of the plurality of bristles 8 is covered by the hygienic coating 16. As a result, the hydrophobic properties keep the removable brush 6 virtually dry upon each use. Additionally, the hydrophobic properties inhibit the growth of microorganisms. Resultantly, the hygienic coating 16 keeps the present invention and the surrounding area germ-free, eliminating any chances of contamination. Therefore, the present invention provides an overall improved device when compared to similar existing inventions.

(12) The tubular enclosure 3 protects and houses the removable brush 6 when the present invention is not in use. As a result, there is no need for a bulky receptacle that collects toilet water and germs. In particular, the tubular enclosure 3 is positioned concentric with the connecting shaft 2, adjacent to the removable brush 6, such that the tubular enclosure 3 fully or partially surrounds the removable brush 6. The tubular enclosure 3 is preferably dome-shaped as seen in FIG. 3 in order to reduce the overall profile of the present invention, thus requiring less storage space. In order to achieve the retractable aspect of the present invention, the tubular enclosure 3 is slidably mounted to the interconnected shaft, opposite the handle 1. This connection allows the present invention to be positioned into two states, a retracted configuration and an extended configuration. In the extended configuration, the tubular enclosure 3 is positioned adjacent to the handle 1, exposing the removable brush 6 to the external environment as seen in FIG. 5. In the retracted configuration, the removable brush 6 is positioned within the tubular enclosure 3 as seen in FIG. 2.

(13) Referring to FIG. 6, the retractable aspect of the present invention is accomplished through a retracting mechanism 17. In particular, the retracting mechanism 17 is mechanically integrated in between the tubular enclosure 3 and the connecting shaft 2. As a result, the tubular enclosure 3 is concentrically and slidably mounted to the connected shaft by the retracting mechanism 17. A variety of mechanisms may be used for the retractable mechanism. In one embodiment of the present invention, a click-and-lock mechanism similar to retractable pens is used as the retracting mechanism 17.

(14) Certain wavelengths of ultraviolet light disrupt cellular functions of microorganisms, thus killing or inactivating said microorganisms. The present invention utilizes this characteristic in order to clean/disinfect the interior of the tubular enclosure 3 and the removable brush 6. This is achieved by the plurality of UV light sources 9. The plurality of UV light sources 9 is distributed about an inner surface 4 of the tubular enclosure 3 with each of the plurality of UV light sources 9 being adjacently connected to the inner surface 4 as seen in FIG. 3. Additionally, each of the plurality of UV light sources 9 is oriented towards an interior of the tubular enclosure 3 and more specifically the removable brush 6. The plurality of UV lights sources kills and/or inactivates residual germs and microorganisms in and around the removable brush 6 after each use of the present invention, thus preventing mold and bacteria from growing on the removable brush 6 and on the inner surface 4 of the tubular enclosure 3. It is preferred that each instance of use of the present invention is followed by the initiation of clean mode, wherein the plurality of UV light sources 9 is activated and turned on for at least six minutes to adequately disinfect and inhibit the growth of bacteria on the surfaces of the removable brush 6. Although, in alternative embodiments the timing may be altered to meet the preferences and needs of the user.

(15) The battery 10 provides the necessary electrical energy for the plurality of UV light sources 9. The battery 10 is internally mounted within the connecting shaft 2. Additionally, the battery 10 is electrically connected to the plurality of UV light sources 9 as seen in FIG. 7. In one embodiment of the present invention, the battery 10 is removably mounted within the connecting shaft 2 in order to allow the user to easy charge the battery 10. A variety of means may be used to turn on the plurality of UV light sources 9 including, but not limited to, an external button, a pre-programmed timer, and other similar mechanisms.

(16) In the preferred embodiment, the means for operating and controlling the plurality of UV light sources 9 includes the use of a cylindrical base 11, an enclosure-receiving cavity 15, and a magnetically actuated switch 12. The cylindrical base 11 is used to support the tubular enclosure 3 and the internal components for storage purposes, preventing any residual contaminated water on the removable brush 6 from spilling onto the floor. In particular, the enclosure-receiving cavity 15 concentrically traverses into the cylindrical base 11 and is shaped/sized to the compliment the tubular enclosure 3. The magnetically actuated switch 12 serves two main purposes, to attach the tubular enclosure 3 to the cylindrical base 11 and to activate the plurality of UV light sources 9. The magnetically actuated switch 12 comprises a first annular magnetic band 13 and a second annular magnetic band 14. Additionally, the magnetically actuated switch 12 is electrically connected between the plurality of UV light sources 9 and the battery 10. The first annular magnetic band 13 is adjacently connected to the cylindrical base 11. Complimentary to the first annular magnetic band 13, the second annular magnetic band 14 is concentrically integrated into a rim 5 of the tubular enclosure 3, opposite the handle 1 as seen in FIG. 3. In order to store the present invention on the cylindrical base 11, the rim 5 of the tubular enclosure 3 is concentrically positioned within the enclosure-receiving cavity 15. The tubular enclosure 3 is attached to the cylindrical base 11 by the magnetic attraction between the first annular magnetic band 13 and the second annular magnetic band 14. A variety of mechanisms may be used for the magnetically actuated switch 12 such as a reed switch. When the first annular magnetic band 13 comes into the proximity of the second annular magnetic band 14, electrical energy is supplied to the plurality of UV light sources 9 by the battery 10 for a preset amount of time, thus initiating the clean mode. In general, the battery 10 is electrically connected to the plurality of UV light sources 9 by the magnetically actuated switch 12.

(17) In alternative embodiments of the present invention, the plurality of UV light sources 9 is controlled through traditional electrical switches. In one embodiment of the present invention, an electric switch is integrated in between the tubular enclosure 3 and the cylindrical base 11 such that when the tubular enclosure 3 is positioned within the cylindrical base 11, an electric circuit is completed which turns on the plurality of UV light sources 9. In another embodiment of the present invention, a pressure sensor is integrated into the rim 5 of the tubular enclosure 3. Resultantly, when the tubular enclosure 3 is placed on the ground or within the cylindrical base 11, the plurality of UV light sources 9 is turned on for the preset amount of time.

(18) In an alternative embodiment of the present invention, the plurality of UV light sources 9 and the battery 10 are integrated into the cylindrical base 11. In particular, the battery 10 is internally mounted within the cylindrical base 11. The plurality of UV light sources 9 is positioned within the enclosure-receiving cavity 15 and adjacently connected to the cylindrical base 11. This embodiment stores the electrical and hygienic aspect of the present invention in the cylindrical base 11 for easy replacement. Similar to the preferred embodiment, when the tubular enclosure 3 is positioned within the enclosure-receiving cavity 15, the first annular magnetic band 13 interacts with the second annular magnetic band 14 in order to turn on the plurality of UV light sources 9. The plurality of UV light sources 9 then illuminates the space within the tubular enclosure 3 and the removable brush 6 with ultraviolet light in order to inhibit the growth of microorganisms. To further ensure that each of the plurality of bristles 8 is illuminated by the ultraviolet let, the inner surface of the tubular capsule is covered with a highly reflective surface.

(19) Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
