Automatic bathroom flushers with modular design
First Claim
1. An automatic toilet room flush valve, comprising:
- a valve body including an inlet and an outlet and a valve seat inside the body;
a valve member cooperatively arranged with said valve seat, said valve member being constructed and arranged to control water flow between said inlet and said outlet, movement of said valve member between open and closed positions being controlled by water pressure inside a pilot chamber;
an external cover designed for enclosing an electronic control module comprising a battery, and a sensor and said external cover enclosing an actuator for controlling operation of said flush valve; and
a plastic housing located inside said external cover constructed to enclose said electronic control module in a sealed arrangement,wherein said external cover including at least two removable cover parts, said external cover being attachable and removable with respect to said valve body, and wherein said external cover is attached to said valve body in a manner also attaching said plastic housing, located on an alignment member, with respect to said valve body.

Abstract
A bathroom flusher includes a flusher body, a valve assembly, an electronic control system, and a flusher cover. The flusher body includes an inlet and an outlet, and is designed to accommodate the valve assembly that controls water flow between the inlet and the outlet. The valve assembly includes a valve member movable with respect to a valve seat providing a sealing action based on applied pressure on the valve assembly. The bathroom flusher also includes an external cover designed for enclosing an electronic control module comprising a battery, a sensor, and an actuator for controlling operation of the flush valve, wherein the external cover includes at least two cover parts separately removable, and wherein the external cover is attachable with respect to the valve body in a manner also allowing removable attachment of the control module.
