A douche (2) includes a cistern, a filtration vessel above the cistern, and a heater at the bottom, and a closed power cabinet to the lower by the cistern; the power cabinet contains a pump with one end of the pump connected to the cistern and the other end extending out of the power cabinet with a supply line and connected to a serpentine pipe having one end disposed with a lever nozzle, a recessed hole on the power cabinet for the lever nozzle to hook on, and the heated water is pumped to the lever nozzle.

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention is related to a douche, and more particularly, to one in a construction to allow easier improve assembly and more convenience in use.

(b) Description of the Prior Art

For hygienic purposes, a flush toilet is provided with a control valve connected via supply line to a refill valve in a cistern and a lever nozzle stick out in the toilet to deliver water at a pressure regulated by the control valve through the lever nozzle for the user to rinse after the use of the toilet. However, such a system is fixed at where between the toilet and the cistern, it creates a problem to clean the bathroom. The scope of the rinse is restricted since the lever nozzle is positioned in the toilet. The nozzle is vulnerable to be contaminated by the urine or excrements to prevent from any hygienic use. To correct those flaws, this applicant has invented a douche granted with a utility patent (U.S. Pat. No. 91,299,275).

Referring toFIG. 1, the douche is essentially comprised of a main unit1, a pump2and a lever nozzle for rinse. Wherein, the main unit1is divided into two chambers with a partitioning board11. The upper chamber12is fixed at its top opening a funnel water inlet13and a layer of filtration sponge14is disposed at the bottom of the water inlet13to prevent contaminants from entering into the upper chamber12. Meanwhile, a heating element15is provided on the partitioning board11to heat the water admitted by the filtration sponge14and the pump12is fixed at where beneath the partitioning board11.

A switch16is provided on the outer wall closer to the bottom of the main unit1. The pump is connected with a supply line21to the upper chamber, and with a water pipe22to the lever nozzle3, which is hooked onto a water pipe accommodation mechanism disposed by the upper end of the main body. The water pipe accommodation mechanism contains a reel161to wind up the water pipe and the reel16contains a return spring to freely wind up or delver a water pipe31. When the lever nozzle is pulled externally, the water pipe31allows extension for a proper length. When the lever nozzle3is hooked on the accommodation mechanism17, it is automatically to be wound up by the reel161. Furthermore, a touch switch32is provided on the lever nozzle and is connected with a power cable33to the pump2. The depressed touch switch32starts the pump2to suck in the heated water from the upper chamber12through the supply line21to be ejected from the lever nozzle3following the water pipe22. A handle34and a lever35of the lever nozzle3are screwed to each other and a nozzle36is disposed at a right angle to the head of the lever35. Upon completing the use of the toilet, the lever nozzle3is fetched from the water pipe accommodation mechanism17and extended into the toile, then the touch switch is depressed for the nozzle at the head of the lever nozzle3to eject lukewarm water to allow the user adjust the ejection angle of the lever nozzle3.

Whereas the douche relates to a standalone system and provided with casters18at the bottom of the main unit1, it may be placed wherever is convenient to the user. The lever nozzle3will not be contaminated since it is placed in the toilet when the use is required. For even more personal sense, each user may have his/her own lever35and connect it to the handle34of the lever nozzle3whenever he/she uses the toilet and then remove the lever35from the handle34after the use. However, the douche may be further improved to upgrade its functions.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a douche that permits easier assembly and more convenient use. To achieve the purpose, a cistern is provided at where by a main unit of the douche. A filtration vessel is provided on the top of the cistern, and a heater is provided at the bottom of the cistern. A closed power cabinet is provided at where below the side of the cistern. A pump is provided at the bottom in the power cabinet. One end of the pump is connected to the cistern and the other end extending from the power cabinet and connected to a serpentine pipe disposed with a lever nozzle at its head. A recessed hole is provided on the power cabinet to be hooked on by the lever nozzle. The heated water is pumped to the lever nozzle for the rinse.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring toFIGS. 2, and3, a preferred embodiment of the present invention is essentially comprised of a cistern4provided on one side to the main unit of the douche; a closed power area5disposed at where below the side of the cistern4. That is, both of the cistern4and the power area5are next to each other. Wherein, a lid41provided on top of the cistern4is used to cover up an opening to a filtration vessel42. Multiple layers of filtration materials are filled in the filtration vessel42. A heater43and a water level sensor44are provided at the bottom of the cistern4. A pump51is provided at the bottom in the power area5. One end of the pump51is connected with a supply line52to the cistern4and another end of the pump51extends out of the wall of the power area with a delivery line53and is further connected to a serpentine pipe54. The head of the serpentine is connected to the lever nozzle6and a nozzle61is screwed to the head of the lever nozzle6. A press switch62is provided at where appropriately to the lever nozzle6to control the passage inside the lever nozzle6. When the switch62is depressed, the water is delivered and when released, blocked. A recessed holder55is provided on the wall on the upper part of the power area5to lock the lever nozzle6in place when not used. A pressure switch56is provided on the inner wall of the holder55and connected to the power that activates the pump51. Accordingly, when the lever nozzle6is hooked on the holder55, the pressure switch is in turn depressed by the lever nozzle to interrupt the power supply to the pump51. When the lever nozzle6is off hook from the holder55, the pressure switch56is released from the lever nozzle6and the pump51is started. The pump51automatically jumps to stop operating upon the expiry of a preset length of time even the pressure switch56is not depressed within the preset time. The overload protection circuit for the pump51is of the prior art and will not be elaborated herein.

Whereas the pump51is provided in the power area5to the side of the cistern5, concerns over the waterproof and fastness of the partitioning board and whether the partitioning board could withstand the weight of the pump51as found with the prior art are eliminated for assurance of the service life the pump51. Multiple layers of filtration materials provided in the filtration tank42filter away foreign matters and minerals in the water in a more effective way to keep them away from being build up on the heater43for maintaining its normal function. Once the water level in the cistern4drops to a certain extent or the temperature of the water gets abnormally high, the water level sensor44provided at the bottom of the cistern4and a temperature sensor45is provided on the wall of the cistern4. Once the water level drops to its lower limit or the water temperature gets too high, the overload protection circuit will automatically jump to kill the pump5for maintaining use safety.

A serpentine pipe54is used in the present invention to replace the reel adapted with a return spring in the prior art for lowering production cost and easier assembly. The nozzle61may be screwed to the lever nozzle6to better meet personal hygiene since each member in the family has his/her own dedicated nozzle61. Furthermore, as illustrated inFIG. 4, the douche is mounted to a wall71at where closer to a toilet8in a bathroom7to prevent from interfering with the personal movement in the bathroom7.
