Electric drainage valve for toilet bowl

Abstract

The invention discloses an electric drainage valve for a toilet bowl. The electric drainage valve for the toilet bowl comprises a valve seat, a water-stopping bonnet, a valve body, a valve head, a manual water flushing mechanism and an electric device, wherein the valve head or the valve body is provided with a vertical fixed pulley; the lower end of a rope in the fixed pulley is connected with the water-stopping bonnet; and the upper end of the rope in the fixed pulley turns via the fixed pulley, and then is connected to the electric device which is eccentrically placed in the center of the valve head. The fixed pulley is small in functional size, and can keep away from other devices in the structure of the drainage valve for the toilet bowl, so that a manual water flushing function can be fulfilled completely while an automatic water flushing function is fulfilled; and an outputting shaft of a decelerating permanent magnet stepping motor is downwards arranged on one side of the valve head, and the integral height of the electric drainage valve for the toilet bowl can be reduced. The electric drainage valve for the toilet bowl has the advantages of simple structure, compactness and high universality, and is suitable for water tanks of all toilet bowls.

Description

technical field [0001] The invention relates to an electric drainage device, in particular to an electric drainage valve for a toilet. Background technique [0002] The toilet electric drain valve is a drainage device used in toilet tanks such as toilets, squatting pans, and bidets; it includes a valve seat with a fixed end of the water tank, a water stop valve cover matched with the valve seat, and an overflow valve connected to the drain hole of the valve seat. A water pipe, an electric device and an electric transmission part for lifting the water stop valve cover, the electric device is connected to the water stop valve cover through the electric transmission part. The electric drain valve of the toilet can be fixed in the water tank of the toilet, and the circuit of the electric device is electrically connected with the control circuit, which can realize automatic flushing of the toilet; so that the person who uses the toilet does not touch the flushing water, which is ...

AI Technical Summary

Problems solved by technology

Although some deficiencies have been made up for after the improvement, there is no choice of high-speed flushing or low-speed flushing during manual flushing, which will cause waste of water resources; secondly, the electric device is placed above the drain valve, which increases the The overall height of the electric drain valve makes it impossible to use the lower toilet water tank, which affects the versatility; moreover, one of the double-level drain buttons is invalid, and the invalid flush button on the water tank cover is pressed by mistake in a public place. will not flush, which will cause inconvenience to the user
