Background

As is well known, the intelligent closestool is a sanitary revolution, and since the invention of the intelligent closestool, people can conveniently solve the problem of scattering in the household environment, and can enjoy the convenience of automatic buttocks cleaning besides not being troubled by odor and bacteria and viruses. However, it is a worldwide problem to solve the problems of taste, vision, cleaning and preservation of excrement and automatic wiping of buttocks when spreading in a water-free and relatively closed or relatively small space such as a hospital bed, an automobile and other transportation means. Even in the U.S. hospitals in developed countries, patients still use the simple old bedpans in the sick bed, and the taste during the use and the taste and the vision during the cleaning after the use are very unfriendly; the problem of defecation of automobiles, tank drivers and fighter pilots, particularly females during driving or flying is solved, and even the army of the super-technology China does not have an ideal solution.

In order to solve the above problems, engineers have devised various solutions. On the Chinese patent network, one technical route is that a portable bedpan is matched with substances such as stool and urine firming agents, and the cost is high, and the automatic hip cleaning function is not available; another technical route is that the portable toilet bowl is provided with a plastic bag tightening and sealing mechanism, such as the patent with the patent number CN2007002287(WO2008049304a1), but the portable toilet bowl needs to manually tighten and seal the plastic bag, has no automatic buttocks cleaning function, and uses an exhaust pipeline to pump the defecation odor out of the window of the automobile (needless to say, the point determines that the portable toilet bowl cannot be used on hospital beds and in tanks); the technical difficulty of automatically cleaning buttocks (buttocks) with a paper towel is far more than that of using water, for example, the patents of CN201080041491.4 and CN201680015768.3 applied by Japan company in China, the design and production of a special wiping head and a multi-joint robot hand are required, the structure is complicated, the cost is high, and the automatic cleaning device is not suitable for a portable mobile toilet or a bedpan.

With the development of science and technology and the improvement of the civilization level of human beings, a portable intelligent closestool or bedpan which is low in price, easy to popularize and capable of being used in water-free and relatively closed spaces or relatively small spaces such as hospital beds, automobiles, tanks and other transportation and combat vehicles is urgently needed in the market.

The present invention has been accomplished in view of the above.
