DETAILS DESCRIPTION OF THE INVENTION
-
The present invention SEPTICTEK 10 as shown on FIG. 2 will provide the water spray device in which the device will perform the sanitary water spray cleaning the private part namely the anus area after the stool discharge instead of toilet paper 24. The handy light weight handle 16 will spray the intended body part with the water from the water tank 11 and pump/motor 12 via the flexible hose 15 and spray nozzle 17 which should be washed and cleaned with the flush water from toilet tank before and after stool discharge.
-
The motor/pump 12 will release some heat to warm the tap water when it is in operation and it is quiet. There is screen 14 to prevent any particles and debris. The bolted lid 11A can be opened for maintenance when needed.
-
The new invention is different from the water pik for teeth cleaning because the pik has the horizontal impeller assembly with high impact noise for the water spray jet at high speed.
-
The user can pour into the water tank 11 with warm water into the air release 18 from the nearby faucet tap water at user preferred temperature moments before sitting down on the toilet seat. The components are all connected and this is a device that is designed for simplicity and ease of use. The portable device will be placed on top of the existing toilet flush tank 26 or other support behind the toilet seat as shown on the FIG. 6.
-
The auto on and off switch for the cleansing operation is controlled by the receiver 20 and the wireless transmitter 20A will hang over the user's shoulder thus it's button can be easily touched by the user's hand while at the toilet seat as shown on FIG. 6 and FIG. 6A. The device can also be controlled by the user's foot if he or she has lost one hand and if the floor switch is placed nearby the toilet seat. The device shall connect to the said receiver 20 first then connect to the household 120 V outlet (GFCI) 23. When the SEPTICTEK 10 is not being used, the said hose 15 shall be hung around the said water tank 11 for safe keeping 25. The said spray nozzle 17 should be covered with towel or paper to prevent dusty and keep in a sanitary condition.
-
The SEPTICTEK 10 will turn off when the water is too low and it will make small warning noise because of air intake instead of water at the said motor/pump 12.
-
However, in situation where there is no household electricity available for said outlet 23 or in travelling, the SEPTICTEK 10 can be operated with 12V DC lithium ion battery 23A with DC motor/pump 12A embodiment as shown on FIG. 8 instead of said standard AC motor/pump 12.
-
The nozzle 17 is an integral part of the device and the opening size cross section is small enough to deliver the adequate pressure and velocity V=Q/A toward the spray area where the Q is the constant flow rate GPM from the hose 15 which is connected to the water tank 11 and small immersion electric motor/pump 12 with low power at less than 0.5 Amp (120 ACV/60 Hz).
-
The said nozzle 17 will also deliver the water in part, by the gravity flow at 0.433 psi per foot of head over the toilet seat. The tap water contains chlorine which is a good disinfectant on skin.
-
The cleaning operation takes about 1 to 2 minutes in norm to empty the said water tank 11 and in the meantime, the cleaning task shall be complete. However, the task will also depend on the fresh discharge quality and quantity from the daily food intake. The quality is good and easy to clean if more veggie and fruit with high fiber diet and less red meat. If it takes more time, the user will have to refill the tank 11 with warm water again and again. For high efficiency, the operation may need both user's hands: one hand holds the spray nozzle upward toward the anal area and at the same time, the other hand pulls the buttock muscle away from the anal opening while sitting on the toilet seat similar to by walking on the high stairs.
-
It is understood that the preferable embodiment may be comprised of other materials that are more expensive and decorative, said materials being known to those of skill in the art. It is further understood that the present invention is not limited to the embodiment described above, but may encompass any and all embodiment as described herewith.
