Description

    CROSS REFERENCE TO RELATED INVENTIONS
  • Not Applicable
    • BACKGROUND OF THE INVENTION
  • Ultraviolet light has been used to kill microorganisms, molds and fungus in various applications. For safety concern, UV treatment generally takes place inside an enclosed UV exposure compartment and is effective in both air and water. Ultraviolet light kills microorganisms by damaging its DNA. UV light will destroy chemical bonds that tie DNA atoms in the microorganism. Extended exposure under UV light is necessary to ensure complete kill of all microorganisms.
  • UV light, with wave length smaller than 360 nm (smaller than 300 nm has the highest penetration power), can penetrate the outer cell membranes of microorganisms such as viruses, bacteria, mold and mildew. The UV light modifies the DNA, forcing it to replicate incorrectly and subsequently causing the death of the microorganism.
  • By installing UV LEDs and functional control circuit(s) on the toilet cover and forming an enclosed UV exposure compartment with toilet seat, UV sanitization process can be achieved effectively, automatically, safely and quickly. The functional control circuit(s) will provide sensing, monitoring and controlling functions including, but not limiting to following:
      • 1. Using micro switch(s) and/or motion detecting sensor(s) and/or photo sensor(s) to ensure toilet seat or toilet cover is in designated docking position and forms an enclosed compartment by toilet cover and toilet seat,
      • 2. Constantly monitoring above safety interlock switch/sensor(s) status to ensure operational safety,
      • 3. Activating or deactivating UV LEDs for a pre-programmed period of time to ensure effective sanitization process and
      • 4. Provide manual control, either locally or remotely, to extend or add additional UV sanitization cycle.
    BRFIEF SUMMARY OF THE INVENTION
  • The sanitization mechanism of the toilet seat is proposed, which comprises: Ultraviolet (hereinafter referred to as UV) LEDs, control circuit(s) of power, driver, timer, safety, micro switch and or sensor-activated docking confirmation, to automatically activate or deactivate the UV LEDs, and an enclosed compartment between toilet seat and toilet cover which allows UV light traveling and sanitizing. The UV sanitization mechanism can sanitize quickly and effectively, reducing toilet seat paper or restroom chemicals consumption, especially in high traffic public locations.

    DETAILED DESCRIPTION OF THE INVENTION
  • The sanitization process works with both toilet seat and toilet cover in vertical or horizontal position (relative to the toilet bowl).
  • FIG. 1 is a front perspective view (with both toilet seat and cover in vertical position, relative to the toilet bowl) of external appearance of the sanitization mechanism of toilet seat of the first preferred embodiment of the present invention. The toilet seat 5 is either manually or automatically raised toward the toilet cover 4 forming the enclosed compartment 2 after usage. By using micro switch(s) and/or motion detecting sensor(s) and/or photo sensor(s) 6 to ensure toilet seat 5 is in designated docking position and forms the enclosed compartment 2. Once toilet seat 5 docking safety interlock 6 is confirmed, UV LEDs 1 driver and timer on control circuit(s) 3 will turn on the UV LEDs 1 for sanitization process for a pre-programmed period of time. Furthermore, user can press the push button 7 or 7′ on either side of toilet cover 4 to extend or add additional sanitization cycle when needed.
  • FIG. 2 is a top view (with both toilet seat and cover in vertical position, relative to the toilet bowl) of external appearance of the sanitization mechanism of toilet seat of the first preferred embodiment of the present invention. The enclosed compartment 2 forms by docked toilet seat 5 and toilet cover 4 provides a safe passage for UV light to travel. The UV LEDs 1 placement in first embodiment utilize indirect, reflective UV light exposure arrangement to minimize UV light leakage and is suitable for toilet cover 4 and toilet seat 5 in vertical application (relative to the toilet bowl). In addition, toilet seat 5 can have a small flange along the edge on both sides to further minimize UV light leakage.
  • FIG. 3 is a bottom view (with both toilet seat and cover in horizontal position, relative to the toilet bowl) of external appearance of the sanitization mechanism of toilet seat of the second preferred embodiment of the present invention. The toilet cover 4 is manually or automatically lowered down onto the toilet seat 5 forming the enclosed compartment 2 after usage. By using micro switch(s) and/or motion detecting sensor(s) and/or photo sensor(s) 6 to ensure toilet cover 4 is in designated docking position and forms the enclosed compartment 2. Once toilet cover 4 docking safety interlock 6 is confirmed, UV LEDs 1 driver and timer on control circuit(s) 3 will turn on the UV LEDs 1 for sanitization process for a pre-programmed period of time.
  • FIG. 4 is a front view (with both toilet seat and cover in horizontal position, relative to the toilet bowl) of external appearance of the apparatus of the second preferred embodiment of the present invention. The UV LEDs 1 placement in second embodiment utilize direct UV light exposure arrangement to maximize UV sanitization effectiveness and is suitable for toilet cover 4 and toilet seat 5 in horizontal position (relative to the toilet bowl).The UV LEDs 1 provide direct UV light exposure onto toilet seat 5 surface. The effectiveness of UV sanitization can be further enhanced with reflective coating or titanium dioxide coating 8 on toilet cover 4. Furthermore, user can press the push button 7 or 7′ on either side of toilet cover 4 to extend or add additional sanitization cycle when needed.
  • FIG. 5 is a front view (with both toilet seat and cover in vertical position, relative to the toilet bowl) of external appearance of the apparatus of the third preferred embodiment of the present invention. The toilet seat 5 is either manually or automatically raised toward the toilet cover 4 forming the enclosed compartment 2 after usage. By using micro switch(s) and/or motion detecting sensor(s) and/or photo sensor(s) 6 to ensure toilet seat 5 is in designated docking position and forms the enclosed compartment 2. Once toilet seat 5 docking safety interlock 6 is confirmed, UV LEDs 1 driver and timer on control circuit(s) 3 and 3′ will turn on the UV LEDs 1 for sanitization process for a pre-programmed period of time. The UV LEDs 1 placement in third embodiment utilize direct UV light exposure arrangement to maximize UV sanitization effectiveness. Furthermore, user can press the push button 7 on a locally wired or remotely wireless controller unit 9 to extend or add additional sanitization cycle when needed.
  • While the preferred embodiment and various alternative embodiments of the invention have been disclosed and described in detail herein, it may be apparent to those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope thereof.
