Abstract
The utility model relates to a spray type water-saving lavatory device which comprises a basin cavity of the lavatory device and a water storage folding device, wherein an ejector nozzle is arranged at the junction position of the rear side wall of the basin cavity and a notch plate, and the ejector nozzle is communicated with a control valve via a fluid jet connection pipe. The control valve and a water supply pipe are communicated, and a water replenishment tank and the fluid jet connection pipe are communicated. At least one flooding nozzle is arranged in the basin cavity, the nozzle and a cleaning control valve are communicated via a cleaning connection pipe. Because high-pressure spraying flow crushes rapidly dejecta in the water storage folding device and the dejecta is brought out into a drainage, the water cleaning effect is enhanced, the water consuming amount is cut down, and the crushed dejecta is not easily pasted with a blow-off line. Therefore, jam is not caused. The utility model removes a water chamber and saves lavatory space.
Description
The utility model relates to the lavatory tool, particularly the injecting type water-saving toilet tool.
The general Z-shaped traps that adopt of the outlet of existing lavatory tool pelvic cavity and the sealing between the sewer more, the trap role is a water-stop, prevent that the sewer foul smell from overflowing, the trap height is big more, and water is many more, and it is good more to seal, just thing and flushing water in the trap are discharged by siphon principle, the trap water is many more, washes difficultly more, and water consumption is also just big more.In addition, existing lavatory tool generally all has water tank, can not directly utilize the water source that has the weighing apparatus pressure that provides by variable frequency pump or the water storage box in building to supply water, owing to the parts in the tool water tank of lavatory damage easily, so often cause the evaporating, emitting, dripping or leaking of liquid or gas phenomenon, and lavatory tool pelvic cavity is difficult for rinsing well, blow-off line easily stops up, fouling, for this reason, anxious a kind of developing result to be supplied is good, the lavatory tool of water saving and good seal.
The purpose of this utility model provides a kind of injecting type water-saving toilet tool, wherein is provided with the high-pressure spray nozzle at trap.
A kind of injecting type water-saving toilet tool that the utility model provides, comprise a pelvic cavity and a trap, it is characterized in that also comprising control valve, the jet tube connector, jet nozzle, the flushing tube connector, at least one flooding nozzle, and water supply tank, described jet tube connector extends downward the junction of weir plate with the shape that matches with tool chamber, lavatory basin rear wall from pelvic cavity top, and its lower end is towards the direction parallel with weir plate, described jet nozzle is connected in the bottom of jet tube connector, its axis is parallel with weir plate, and described jet tube connector is connected in an outlet of control valve, and described flooding nozzle is located at the below of pelvic cavity circulation body, be connected in the flushing tube connector, the flushing tube connector is connected in another outlet of control valve, and described water supply tank is connected with the jet tube connector, and feed pipe is connected in the import of control valve.
Wherein, described water supply tank has a venting one way valve.
Wherein, described water supply tank is connected with a detergent for toilet adder, and described adder has a detergent for toilet valve of being opened by the control of the pressure of water supply tank.
Wherein, described jet tube connector and flushing tube connector are connected to the side of a matrix, and described matrix is connected in the outlet of control valve by water inlet pipe, and described water supply tank is connected in water inlet pipe.
Wherein, described matrix is provided with on one feeding conduit and feeding conduit once, front end at described matrix has downward fan-shaped seam in the direction perpendicular to the matrix axis, described fan-shaped seam is communicated with the described feeding conduit of going up, be formed for washing the fan nozzle at pelvic cavity rear portion, back at described fan-shaped seam, downside at matrix has an inclination spray orifice, described spray orifice is communicated with described feeding conduit down, be formed for impacting the just impulse nozzle of thing, described flooding nozzle is symmetricly set on the both sides of matrix by the flushing tube connector, and described flooding nozzle is communicated with the described feeding conduit of going up, and is formed for washing pelvic cavity two sides and anterior nozzle.
Wherein in last feeding conduit, be provided with a water-quantity regulating device.
The utility model is owing to install a jet nozzle in trap, the high-pressure spray that utilization is provided by water supply line smashes the ight soil in the trap rapidly and takes out of and enters sewer, thereby improve the bath effect, and reduced water consumption, toilet-flushing water consumption only is 1/5th of a former water supply volume, the just thing that is crashed to pieces is difficult for sticking on the blow-off line, therefore is difficult for resulting in blockage.Removed water tank, reduced element, stopped because the evaporating, emitting, dripping or leaking of liquid or gas phenomenon that the water tank component wear causes, and saved the space, lavatory, utilized the space of saving, the handrail chair can be installed, locker etc.Because the supplementing water consumption seldom, like this, the consumption that adds the detergent for toilet that is used for scale removal, deodorization in supplementing water just can be seldom.
