Definitions

  • the present invention relates to a sterilizer for a toilet spray attachment.
  • Umann's U.S. Patent No. 2,875,450 disclosed a device for automatically applying water for cleansing purpose and for applying forced draft of warm air to the cleansed parts of the user's body, which however did not provide means to apply sterilizing agent or cleaning chemical on the user's body for enhanced hygienic purposes.
  • the spray nozzle includes a water passage communicated with the water conduit and having an outermost end portion of the water passage formed with a water injection hole inclinedly projecting upwardly, a chemical liquid passage communicated with the delivery tube having an outermost end portion of the chemical liquid passage formed with a chemical injection opening which is positioned above the water injection hole, a partition plate separating the water passage and the chemical liquid passage, and the mixing portion formed as a spray cone portion divergently formed on an outermost end portion of the partition plate for mixing water sprayed from the water injection hole and chemical liquid drained from the chemical injection opening.
  • Each sterilizer (7) includes a liquid reservoir (71) having a top cover (72) drilled with a venting hole (73) in the cover (72), a delivery tube (74) connected with the reservoir (71), a mixing portion (75) perpendicularly connected with the lower portion of the tube (74), a sealer (77) resiliently held by a spring link (76) which is secured towards the mixing portion (75) to normally seal a lower port (78) of delivery tube (74) and operatively opened by a downcoming water from pressurized water source and a mixing mesh (79) inserted in the mixing portion (75).
  • the reservoir (71) may be filled with sterilizing agents or cleaning chemicals A for enhanced hygienic cleaning purposes for the toilet users.
  • the boosting pump (32) will then be omitted.
  • a cushion (23) for providing an actuating rod (86) thereon may be suitably selected from a plurality of cushions (23) fixed under the lower plate (22) of the toilet seat (2).
  • the cushion (23) as shown in Figure 2 is pivoted about an inner elastic nail (24) serving as "fulcrum” to stably ride on bowl (1), when the outer rod (86) is biased downwards by the spring plate (85).
  • the cylinder body (81) includes: an upper cylindrical hole (811) for inserting the spring (84) therein, an inverse truncated-cone hole (812) adjacent to the hole (811) engageable with the plug (82) shaped as inverse truncated cone, a lower cylindrical hole (813) formed under the truncated-cone hole (812) and having a diameter smaller than that of the upper hole (811), a liquid inlet hole (815) fluidically communicated with the upstream tube portion (741) and a liquid outlet hole (816) fluidically communicated with the downstream tube portion (742). Both holes (815), (816) are fluidically communicated with the inverse truncated-cone hole (812) and capable of being sealed by the plug (82) shaped as inverse truncated cone.
  • the depression by the user's gravity on the toilet seat (2) will bias the cushion (23) and its actuating rod (86) upwards to raise the stem portion (83) of the plug (82) to open the liquid holes (815), (816) to flow chemical liquid from reservoir (71) towards either nozzle (5) or (6) and whereby upon the opening of valve (41) or (42), the water will be sprayed through either nozzles (5) or (6) to mix the chemical liquid in the cone portion (56) or (66) for hygienic flushing purpose.
  • the spring plate (85) will bias the cushion (23) downwards to recover the plug (82) which is also restored by the spring (84) to close the liquid holes (815), (816) to stop liquid drainage.
  • the user wants to adjust the liquid quantity or to stop the liquid supply, he or she may close the valve (740) of the chemical tube (74).
  • the stem (83) Upon the depression of toilet seat (2), the stem (83) will be raised to move the packing plunger (82a) upwards to open the holes (815), (816) whereby the liquid from upstream tube (741) will flow through the aperture between the rod portion (82b) and the cylindrical hole (811) towards the downstream tube (742) for end use.
