ABSTRACT:
TECHNICAL FIELD
The present invention relates to toilet equipment, in particular, to toilet equipment that is dry and sealed.
BACKGROUND TECHNOLOGY
To promote environmental protection people are becoming more and more aware of the defects of flush toilets. Therefore there have been various inventions, such as PCT/CN96/00009, which discloses a toilet seat stool which does not require flushing. Though said invention has features for preventing cross-contamination and for providing convenience and sanitation, its transmission is electrically controlled, which may lead to easy mal-operation when its user is not familiar with its structure. It also cannot be used in areas without electricity and water, such as at sea beaches.
SUMMARY
The objective of the present invention is to provide a dry and sealed toilet which operation is controlled by the weight of the human body. The present invention can be described as a fully automatic toilet usable without flushing, including a case body, a shaped cavity, a seat ring provided on said cavity, a plastic cover over the periphery of said case body, an open-close pulling mechanism to pull a plastic bag, provided in said case body for controlling the connection between said shaped cavity and an excrement-holding box fixed under said case body. The case body is fixed on one pedal, and the pedal has one end hinged with the base. The front end of said pedal is a swing end, and there is a pressing spring fixed between its end and the base. The pedal is hinged at least with one crank for controlling the operation of said open-close pulling mechanism, said crank has one end rolling against the supporting board of said base, and the other end is connected with said open-close pulling mechanism.
Another embodiment of the invention can be described as a fully automatic toilet usable without flushing, including a case body, a shaped cavity, a seat ring provided on said cavity, a plastic cover over the periphery of said case body, an open-close pulling mechanism to pull a plastic bag, provided in said case body for controlling the connection between said shaped cavity and an excrement-holding box fixed under said case body. At least one vertically movable controlling rod is provided on the periphery of said plastic cover, said seat ring having one end hinged with said shaped cavity, the controlling rod having its upper end against said ring via a spring fixed thereon. At least one gear is rotatably fixed at the lower part of said controlling rod, said gear being joggled with one fixed rack and one sliding rack, said open-close pulling mechanism being connected with said sliding rack.
The present invention fully utilizes the weight of the human body of the user to automatically control the operation of the open-close pulling mechanism. The toilet is reliable and has good adaptability and may be widely used in such cases as for general family usage, in tourist areas, in long-distance buses, trains, boats and aircraft.
