Bathing device and method thereof

Abstract

A bathing device for washing people's body has a cleaning head comprising a suction housing, a liquid injection assembly inside said suction housing, and a control valve assembly, together with associated accessories. The control valve assembly comprises a valve and an electrical switch, allowing an operator to close said control valve to start spraying cleaning fluid onto person's body and removing said fluid with vacuum, and to open said control valve in said control valve assembly to discontinue spraying cleaning fluid onto person's body and releasing vacuum in said suction housing to facilitate free move of said cleaning head. The bathing device can clean person's body like taking a bath or shower without spilling water to adjacent area and the need for the person taking off clothes, and further at any place of person's convenience or choice.

         2 . The device as claimed in  claim 1 , wherein said suction housing is detachable on said cleaning head. 
     
     
         3 . The device as claimed in  claim 1 , wherein said suction housing has various sizes and shapes to fit specific area and curve shape of human body. 
     
     
         4 . The device as claimed in  claim 1 , wherein the contact edge of said suction housing is made of soft and elastic material to ensure soft contact and vacuum seal with human body. 
     
     
         5 . The device as claimed in  claim 1 , wherein said conduit coupled between cleaning head and waste fluid separator and reservoir is flexible and expandable, allowing free move during bathing process. 
     
     
         6 . The device as claimed in  claim 1 , wherein said tubing coupled between said liquid pump and said liquid injection assembly is embedded inside said conduit coupled between said cleaning head and said waste fluid separator and reservoir. 
     
     
         7 . The device as claimed in  claim 1 , wherein said vacuum pump, said waste fluid separator and reservoir, said clean fluid reservoir, said liquid pump are supported on a movable base with castors. 
     
     
         8 . The device as claimed in  claim 7 , wherein said waste fluid separator and reservoir and said clean fluid reservoir are detachable on said movable base with castors. 
     
     
         9 . The device as claimed in  claim 1 , wherein said clean fluid reservoir further comprises a liquid storage chamber, a detachable cap with connector and tubings in liquid communication with said liquid pump, an electric heating element, and a temperature indicator. 
     
     
         10 . The device as claimed in  claim 1 , wherein said bathing device further comprises a temperature control system to control the temperature of the clean fluid within a designed range with said electric heating element and said temperature indicator. 
     
     
         11 . The device as claimed in  claim 1 , wherein said liquid storage chamber of said waste fluid separator and reservoir is detachable and is vacuum tight by a sealable cap. 
     
     
         12 . The device as claimed in  claim 1 , wherein said waste fluid separator and reservoir further comprises a vacuum releasing valve. 
     
     
         13 . The device as claimed in  claim 1 , and further comprising electric power sources for said temperature control system, said electrical heating element, said vacuum pump and said liquid pump. 
     
     
         14 . The device as claimed in  claim 1 , and further comprising a liquid separator/filter coupled between the outlet of waste fluid separator and reservoir and the inlet of said vacuum pump to further remove liquid entering the inlet of said vacuum pump. 
     
     
         15 . The device as claimed in  claim 1 , wherein said control valve assembly further comprises a valve and an electrical switch, said valve closes air communication of said cleaning head with atmosphere and turns on said electrical switch simultaneously, and said valve opens air communication of said cleaning head with atmosphere and turns off said electrical switch simultaneously. 
     
     
         16 . A method of taking a bath using a bathing device for washing people's body, comprising:
 a cleaning head comprising a suction housing, a liquid injection assembly inside said suction housing, and a control valve assembly, wherein said control valve assembly controls spraying cleaning fluid onto people's body and removing said fluid with vacuum, and said control valve also controls discontinuing spraying cleaning fluid onto people's body and releasing vacuum in said suction housing to facilitate free move of said cleaning head;   a clean fluid reservoir;   a fluid pump coupled between and in fluid communication with said liquid injection assembly and said clean fluid reservoir through flexible tubings;   a waste fluid separator and reservoir, comprising a liquid storage chamber, an air/liquid separator, an inlet coupled to and in air and fluid communication with said cleaning head, and an outlet coupled to and in air communication with a vacuum source;   a vacuum pump coupled to and in air communication with said outlet of said waste fluid separator and reservoir,   wherein an operator closes said control valve in said control valve assembly to start spraying cleaning fluid onto person's body and removing said fluid with vacuum, and opens said control valve in said control valve assembly to discontinue spraying cleaning fluid onto person's body and releasing vacuum in said suction housing to facilitate free move of said cleaning head.
