Wash-free cup structure

Abstract

A manually chargeable flash light comprises a casing, a lamp, and a power system, wherein the lamp is at least an LED (Light Emitting Diode), and the power system is composed of a gear set mechanism, a mini power generator, and an accumulator. The gear set mechanism is connected with a handle, which is connected with a handle arm outside the casing. Comparing to the current techniques, the present invention uses a manually driven power source to replace the conventional battery power, thereby guaranteeing power supply at any time without exchanging batteries. Therefore, the troublesome of depleting batteries without backup can be avoided, and energy can be saved due to the high efficiency of LED. Furthermore, it will not cause the pollution to the environment by waste batteries.

1 . An improved structure of a wash-free cup, primarily comprising a cup, and two extension pieces, wherein the cup is surrounded by the first extension piece, and the second extension piece is fixed on a side of the cup; two ends of the first and second extension piece are overlapped to construct two assembly parts with a latch-able on one end of an assembly part and a buttonhole on one end of the other assembly part; a handle structure facilitating hand holding is constructed by latching the two assembly parts.  
   
   
       2 . The improved structure of a wash-free cup according to  claim 1 , wherein a holding hole is installed on each of the aforementioned assembly parts.  
   
   
       3 . The improved structure of a wash-free cup according to  claim 1 , wherein a detachable design can be applied to the cup and two extension pieces.
