Description

BACKGROUND OF THE INVENTION

[0001] (a) Technical Field of the Invention

[0002] The present invention relates to an improved structure of a self-lifting toilet seat and in particular, a toilet seat which can be smoothly self-lifted up after the seat has been used by a user.

[0003] (b) Description of the Prior Art

[0004] Taiwanese patent publication number 096211 related to a self-timing self-lifting toilet seat and Taiwanese patent publication no. 276480 relates to an improved structure of a self-lifting toilet seat. These conventional seats have the drawbacks of the toilet seat after used is self-lifted but in a position which is protruded from the water tank and the angle thereof cannot be adjusted. If the water tank is too large, these toilet seats cannot be used, and due to the moving of the liquid the self-lifting of the seat is not smooth and may sometime jam and it stops lifting; thirdly when the seat is at 45 degree a resisting force is form to stop the toilet seat from move upward. Forth, when the seat is at 90 degree, due to lacking of an partition between the slot at the front section and the slot at the rear section, the water or liquid at the rear of the slot cannot be precisely flown to the front section of the slot and reverse flow of the liquid is occurred and this will affect the self-lifting of the seat.

[0005] Accordingly, a main object of the present invention is to provide an improved structure of a self-lifting toilet seat, which overcomes the above-mentioned drawbacks.
