RELATED APPLICATIONS  
       [0001]     This application is continuation-in-part (CIP) of prior U.S. patent application Ser. No. 10/731,180 applied on Dec. 9, 2003, which is fully incorporated herein. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of Invention  
         [0003]     This invention relates to an improved toilet system attached a multi-purpose hand held water spraying apparatus, engaging in delivering instant water supply for hygienic and cleaning purposes.  
         [0004]     2. Description of Related Art  
         [0005]     People often desire to obtain a device that may clean their toilet systems and its surrounding areas. At times people may need a device to cleanse soiled areas of their body. My invention is equally beneficial for both needs. The improved toilet system is designed for the cleansing of the user&#39;s body as well as cleaning the toilet fixture using an attached multi-purpose hand held sprayer, creating better hygienic environment. Devices invented for these purposes are presented in the previous arts, but not easily found in the current market. The lacks of practicality and marketability hinder the devices from their production for the consumers.  
         [0006]     As for the function of cleaning the user&#39;s body, there are many competitors in the market that offer personal hygiene devices. One available system is called bidet, but it requires an additional bowl in the bathroom and costs are high for installation. The majority of the other bidet related inventions have sprayers added to the existing toilet systems. The spray nozzles are placed around the toilet in permanent methods, having some drawbacks. Because of the immobility of the sprayer nozzle, some of them require the user to maintain a specific body alignment to obtain better cleansing. Moreover, many devices have need of frequent sanitization because the nozzles stay inside the bowl when used. This invention offers mobility of spraying functions by the user&#39;s choice of insertion and operation, not requiring a specific body alignment and frequent sanitization of the device.  
         [0007]     The function of cleaning the toilet system adds better cleaning environment to the conventional toilet systems. The conventional toilet systems have predetermined water flush passages in the toilet bowl. These flush passages are designed for transporting water into the toilet bowl from a toilet water tank by means of the gravity forces. Therefore, the bowl structure having predetermined water passages restricts the area to be cleaned, and the limited gravity force is frequently not enough to clean the soiled bowl. This invention assists to get over these obstacles by addition of the mobile hand held water sprayer, helping the user for frequent cleaning of soiled bowl and its vicinity.  
         [0008]     The functions of cleaning the toilet system and the user&#39;s body are available in some of the inventions related to the attachments for toilets. A device such as U.S. Pat. No. 6,473,913 to Bell, Sr. discloses a bidet attachment for a toilet having an S nozzle connected to the water hose. A stream outlet valve and a sprayer valve selectively control water flow to the stream outlet and sprayer, respectively. This invention implements a water housing to supply water to the device. A device such as U.S. Pat. No. 5,720,055 to Krist discloses a cleaning and hygienic sprayer. This can be used as a bidet or a cleansing device and a device for cleaning clogged toilets and drains. A spray head is secured at an acute angel in relation to a longitudinal axis of a rigid handle and a secondary unit is independently connected to a water supply for delivery of water to a hand-held spray nozzle.  
         [0009]     However, this invention overcomes many of the drawbacks in other systems, adding more benefits to the conventional toilet system. The current invention implements an easily attachable Y-adaptor to supply water to the system. It adopts a single unit sprayer incorporating a single shut-off valve to simplify the structures of device. Its installation does not take a large space nor require complicated knowledge for the general public. Its components are oriented for heavy duty, accomplishing durable usages for longer time with less frequent maintenances. The systematic structures of this invention are in favor of manufacturing in the industry as well as accommodating in the household. Its external designs and colors are selective to enhance the aesthetic beauties of the toilet system.

The multi-purpose hand held sprayer, namely a “sprayer”, overcomes the drawbacks pertained in the prior arts to achieve a single stream and a multiple streams of water for various usages. The addition of new features to the conventional toilet systems facilitates the user to operate the sprayer. The lengthy sprayer delivers water to a remote area such as a central part of toilet bowl. Its slim body allows the user to place through a limited space while the user sitting on the toilet seat. A single stream of water can be useful for cleaning the toilet bowl and a multiple streams of spray can be utilized for cleansing a part of the user&#39;s body as a bidet purpose.  
         [0011]     The sprayer comprises three components assembled by means of quick connection: a controller, an extension bar, and a spray tip. The controller incorporates a shut-off valve to get instant access of water supply. Its body has a contour for placing in a holder with higher position. The extension bar in communication with the sprayer extents the water to its outlet delivering a single stream for cleaning the toilet system and its vicinity. Its body also has a contour for placing in a holder with lower position. The extension bar contains location points at measured increment aligned on the back as guidelines to facilitate placing the sprayer into the toilet bowl. The spray tip connected to the extension bar has a plug containing multiple holes to deliver various water spraying patterns. Its angled body allows the user to achieve a proper direction of spray when it is used for a bidet.  
         [0012]     A holder for the sprayer is mounted to a side surface on the top edge of the existing water tank. The holder includes a body to place the sprayer and a reversed U-type bracket to hold the body. The body can be placed on the surface using fasteners or an adhesive without a bracket. It also utilizes the reversed U-type bracket to be mounted on the side surface of the water tank. The bracket is placed on the top edge of the water tank and secured by a multiple fasteners above the water level. A holder for lavatory items can be placed on any available surface to place a cleansing agent or any medicine to improve the environment of toilet system. This holder has an I-shape bracket, as an example of another type of bracket, to mount on the topside of toilet water tank with fasteners using holes on the body.  
         [0013]     An outlet of the flexible hose is coupled to the inlet of the sprayer to extend its operation range. Besides, a hose hanger is placed for organization of the flexible hose by utilizing the existing fasteners of the toilet system. The hose hanger has a main rod for placing the hose and a supporting rod to secure. It has an opening to secure tightly a part of the hose and an opening to loosely place the rest part of the hose. An inlet of the flexible hose is coupled to the outlet of a valve. The valve regulates the flow of water through the system. An inlet of the valve is then coupled to a Y-adapter assembly that has an inlet, two outlets, a straight nipple, an angled nipple and a bushing. The inlet is coupled with the existing water supply plumbing fixture through a bushing. The first of the two outlets is connected to the existing water supply line for the toilet water tank via a straight nipple. The second of the two outlets is connected to the inlet of valve via an angled nipple to supply water to the sprayer.  
         [0014]     One of the features improved on the existing toilet system is a toilet seat. The improved toilet seat has an extra small opening at the front adjoining to the existing large opening. It also has a multiple bulging lines on the surface of the frontal area parallel to the edge of the small opening. The bulging lines can be implemented on the surface of toilet bowl at the frontal area, if the toilet seat has a formation of an open end. These extra small opening and the bulging lines on the surface at frontal area facilitate for placing the sprayer into the toilet bowl as guidelines while the user is sitting on the toilet seat. Other features improved on the existing toilet system are cutouts on the edges of toilet water tank and its lid. The cutouts allow the bracket of holder for flush mounting wherein the lid sits on the top of the toilet water tank without lifting or other displacement. The bracket of the holder can adopt a multiple holes on the side of toilet water tank for mounting with fasteners.

         [0043]     The sprayer  10  in  FIG. 2  comprises a controller  101 , an extension bar  103 , and a spray tip  105 . The controller  101  incorporates a shut-off valve  20  to regulate the flow of water received from a pressurized inlet  1015 . Its body  1017  takes a slim and lengthy shape (approximately 1″ Width×1″ Height×5″ Length) and contains a contour  1013  for placing in the holder with higher position. The higher position requires more room of the upper area for the sprayer to be placed in the holder. A coupling element  1016  on the body  1017  is placed to connect to a flexible hose. The body  1017  is further connected to the extension bar  103  to transport water to remote area. The extension bar  103  contains a contour  1039  for placing in the holder with lower position. The lower position requires less room of the upper area for the sprayer to be placed in the holder. This position is necessary when the upper area between a toilet water tank and an object such as a shelf located above has not enough room for the sprayer to be placed in the holder. The extension bar  103  in  FIG. 2  contains location points  1035  aligned on the back as guidelines to facilitate placing the sprayer into the toilet bowl. It takes a slim and lengthy shape for easy placement through a limited opening. Its length is adjusted to obtain the proper application. The outlet  1032  of the extension bar  103  supplies a single solid stream  1037  of water as shown in  FIG. 3 . Its strong spouting water stream  1037  in  FIG. 3  can be utilized to clean the toilet bowl and its vicinity. The extension bar  103  in  FIG. 2  is furthermore connected to the spray tip  105  to provide various patterns of water supply. A plug  1051  on the spray tip  105  has small openings  1052  to provide multiple streams  1055  of water as shown in  FIG. 2 . These multiple streams  1055  of water can be utilized for cleansing the body, serving as a bidet. Its angled body accommodates a proper direction to supply water to the user in the toilet bowl. The body of the spray tip takes a slim shape to be easily placed into the toilet bowl through a limited opening at the frontal area.  
         [0044]     The controller  101  in  FIG. 2  has a coupler  1016  at the inlet  1015  to connect to a flexible hose  30  in  FIG. 1 . The flexible hose  30  is long enough to clean a part of the body and the surrounding area. It has a hose hanger  35  in  FIG. 4  for arrangement in the openings  371 ,  372  of main rod  37 . One opening  371  in  FIG. 4  is a fixed hanging section under the main rod  37 . It holds and fixes a part of the hose from the bottom. A lip  3711  on the opening  371  catches the hose  30  and does not allow the hose slipped out easily. This opening  371  is good for hanging the hose  30  immediately after the valve  40  as shown in  FIG. 1 , immobilizing a certain part of the hose  30 . The other opening  372  in  FIG. 4  is for a free hanging section upwardly to facilitate placing of the rest part of the loosened hose  30 .

The edge  803  in  FIG. 11  of the oval opening  802  shares the same focal point as the outer edge  809 , maintaining constant width for seating. Some inventions have wider area in the middle to establish more room for the purpose of comfortable seating. However, an improved toilet seat  80  in this invention provides an additional small opening  804  for the room of easy placement of the sprayer while the user sits on the toilet seat. As shown in  FIG. 1 , a body  801  of the improved toilet seat  80  contains an additional small opening  804  at the frontal area, adjoined to the existing large oval opening  802  of the conventional toilet seat. The additional small opening  804  is established from the area for seating. Besides, the location points  805  are added around the frontal edge of the additional small opening  804  in  FIG. 11 , serving as guidelines for easy placement of the sprayer into the toilet bowl. The waveform of these location points  805  as shown in  FIG. 11A  is located on the surface of the improved toilet seat at frontal area, guiding placement of the sprayer with the support of the location points  1035  in  FIG. 2  on the extension bar  103 . The additional small opening  804  leaves a narrow width at the frontal area, requiring the fragile frontal area to be fortified. The C-shaped element  807  in  FIG. 11  made of strong material is embedded inside the toilet seat as shown in  FIG. 11A  around the additional small opening  804  to compensate the weakness.  
         [0050]     Some of the conventional toilet seat has an opened end at the frontal area as shown in  FIG. 12 . The toilet seat with opened end offers more room for the user at the frontal area and is generally used for the commercial purposes. For this kind of toilet seat, the location points can be placed on the surface of toilet bowl at the frontal area, as shown in  FIG. 12 . The measured increment of these location points  855  in  FIG. 12A  on the body of toilet bowl  85  serves as guidelines, facilitating placement of the sprayer with the support of locating points  1035  in  FIG. 2  on the extension bar  103 . Therefore, the user can place the sprayer into the toilet bowl for a proper position through a sense of insertion depth using guidelines.
