Abstract
An energy-consumption-free urinal flushing system is composed of a lever plate, a pedal film surface, a stage base, a quick-opening slow-closing valve, an instant switching valve, an upper water pipe, a face wall body and a face wall footing. The lever plate is of a flat plate structure with the middle portion provided with a downwards-extending lever which is perpendicular to the plate surface, and the pedal film surface covers the upper surface of the flat plate in a watertight mode; four sides of the pedal film surface are respectively adhered to the connected stage base and the face wall body. The stage base is an original foot-settling surface of a urinal user and serves as a supporting surface of the lever plate structure. The quick-opening slow-closing valve is connected and communicated with the instant switching valve through the upper water pipe. The quick-opening slow-closing valve and the instant switching valve are respectively arranged on the left surface and the upper surface of the face wall footing, and are supported by the face wall footing and inset into the face wall footing. The upper water pipe is led in the face wall footing and is laid along the face wall footing, enters the face wall body after being connected and communicated with the quick-opening slow-closing valve and the instant switching valve, and then is laid inside the face wall body along the face wall body to the position of a flushing device.
Description
Technical field
The present invention relates to a kind of toilet flushing system.
Background technology
The toilet flushing system of existing toilet flushing system, particularly communal bathroom, each has something to recommend him.Have plenty of by manual operation and realize flushing the toilet after use; What have is by consuming the energy, realizing auto-flushing after an action of the bowels by various electronic robots.For manual system, the dependence due to and notice manual to user, leaves many drawbacks.As forgotten after an action of the bowels bath, it is exactly quotidian situation; Or for being reluctant to touch with one's hand etc. former thereby not cutting flushing the toilet after use, this is also common occurrence.For electronic robot automatic flushing system, because dynamic and static work all will consume the energy, and sensing device is usually malfunctioning, or tetchiness and causing do not wash by water after an action of the bowels or do not stop bath etc., also has drawback.Therefore, how to overcome drawback, cut the waste, the problem that should solve with regard to becoming toilet flushing system.
Summary of the invention
For overcome existing toilet flushing system drawback, cut the waste, realize not only energy-conservation, but also the effect of water-saving, the invention provides a kind of Non-energy-consumption toilet flushing system.It by thick stick plate, pedal face, stylobate, open slow valve, instant on switch valve, upper hose, face wall body and the face wall base of closing wink and form.Thick stick plate is that meta is shaped with the slabbed construction of extending lever downwards perpendicular to plate face, and dull and stereotyped watertight above covers with pedal face; Four limits of pedal face are bonding with the stylobate joining, face wall body respectively.Stylobate is original face of stopping over of urinal user, as the supporting surface of thick stick plated construction.Drive the slow valve that closes wink and by upper hose, be connected perforation with instant on switch valve.Drive slow valve and the instant on switch valve of closing wink and be installed on respectively face wall base and obtain the left side and above, take face wall base as supporting the also embedded surface wall base.The upper hose lead-in surface wall base is also laid along face wall base, through with drive the slow valve that closes wink and be connected perforation, be connected after perforation entering surface body of wall with instant on switch valve; In face wall body, along face wall body, lay to flushometer place again.
The technical solution adopted for the present invention to solve the technical problems is:
Non-energy-consumption toilet flushing system by thick stick plate, pedal face, stylobate, open slow valve, instant on switch valve, upper hose, face wall body and the face wall base of closing wink and form.Thick stick plate is that meta is shaped with the slabbed construction of extending lever downwards perpendicular to plate face, and dull and stereotyped watertight above covers with pedal face; Four limits of pedal face are bonding with the stylobate joining, face wall body respectively.Stylobate is original face of stopping over of urinal user, as the supporting surface of thick stick plated construction.Drive the slow valve that closes wink and by upper hose, be connected perforation with instant on switch valve.Drive slow valve and the instant on switch valve of closing wink and be installed on respectively the left side of face wall base and above, take face wall base as supporting the also embedded surface wall base.The upper hose lead-in surface wall base is also laid along face wall base, through with drive the slow valve that closes wink and be connected perforation, be connected after perforation entering surface body of wall with instant on switch valve; In face wall body, along face wall body, lay to flushometer place again.
The fixed bearing support that is provided with on stylobate, is consolidated with fulcrum axle bed on the left end edge of thick stick plate; Fulcrum axle bed forms hinge arrangement by fulcrum shaft and bearing support and is rotatably assorted.On stylobate, below right-hand member edge and thick stick plate between the stylobate and thick stick plate of meta, be equipped with spring.At the right-hand member of thick stick plate, along meta, be consolidated with receptor site axle bed; Receptor site axle bed is formed and is rotatably assorted by push-pull shaft and connecting rod; Connecting rod is formed and is rotatably assorted by pitman shaft and pull bar.Connecting rod, pitman shaft and pull bar form the push-and-pull operation executing agency of instant on switch valve.In the lower end of the downward lever of thick stick plate, connect one end of a slide fastener, other end articulating one connecting ring of slide fastener.Slide fastener and connecting ring form opens slow pull operation executing agency of closing valve wink.
The invention has the beneficial effects as follows: overcome existing toilet flushing system drawback, cut the waste, realize not only energy-conservation, but also the effect of water-saving.Material therefor, device easily obtain, and system construction is convenient, and the device that relates to enforcement is easy to standardization, and cost of production is low.
