Description:
WATERING DEVICE

TECHNICAL FIELD

The present disclosure relates to a watering device.

BACKGROUND

Typically, a water supply system is installed in a factory, a bathroom, a wash basin, a drinking fountain, a shower stall, a garden, and the like. Such water supply system may include a foot valve system for operation or control applications thereof such as to supply water. Conventional foot valve system includes a number of complex components, such as a housing, a foot pedal, a valve assembly, a diverter element, and the like. Further, opening and closing of the valve assembly is performed by the foot pedal. However, the foot pedal is often reset via an integrated spring mechanism or a Bowden cable, which is not desirable. Thus, there is a need for an improved watering device for water supply system which includes a simple design and eliminates the complex components.

An example of a foot valve system is provided in W.O. Patent Application Number 2,013,058,581 (hereinafter referred to as ’581 reference). The foot valve system includes a frame, a housing member, a base member, a valve unit, a control member, and a pedal. The pedal is supported by the frame. When a user operates the pedal, a pedal operation force transmission unit of the pedal allows transfer of the operating force into rotation of a control member, and intermittently, the rotation of an intermittent member. This rotation of the intermittent member leads to change in opening and closing projection such that an inlet and an outlet of a base member and a continuous groove of the intermittent member are communicated with each other. The ’581 reference discloses the foot valve system which may operate the valve unit using the control member which is rotatably installed on the base member by employing the operating force in accordance with the rotation of the pedal. Further, the pedal includes an elastic member for elastically biasing a link member of the pedal. The elastic member may be preferably formed of a coil spring that generates an elastic force to restore the pedal, based on operation of the pedal by the user. However, the foot valve system of ’581 reference includes multiple parts that are complex in design and assembly. Further, the multiple parts such as the elastic member (i.e., the coil spring) may lead to susceptibility to breakdowns, service overheads and other implementation constrains for common users. The foot valve system may also suffer disadvantages of different arrangements, mechanisms which are employed in order to covert the operating force from the pedal to rotational force. Moreover, the foot valve system seems short of providing different installation arrangements, and multiple modes of operation thereof.
