Description

The full-automatic flushometer of water closet

Technical field

The utility model relates to the water closet flushing system, belongs to field of sanitary ware, can be widely used in hotel, office building, and washroom such as family.

Background technology

Water closet is the most frequently used sanitary fittings of a class, and very close with people's life, application surface is extremely extensive.But existing water closet exists more defective, and two aspects wherein have: one of shortcoming is to use when finishing the back bath, needs hand to touch the flush button switch, thereby causes the mutual disease carrying germ of finger or be stained with pollutant.Two of shortcoming is that existing water closet can be divided into direct-flushing and hydrocone type, and its siphon wc pan causes that easily spray splashes when stool, very disagreeable, for splashproof, can reduce the water amount; The direct-flushing water closet is few because of the water amount, the flower that do not dabble, but the water closet after the minimizing water amount, and stool is bonded on the water closet inwall easily, washes away trouble.

Summary of the invention

The utility model is in order to overcome the defective of prior art, and bath voluntarily behind a kind of use water closet is provided, and presses switch without hand, avoids germina infection; If use the few water closet of water amount, before use can be wetting automatically, the spray that not only do not splash, and also stool is not glued the full-automatic flushometer of water closet of tub wall.

The technical scheme of the full-automatic flushometer of the utility model water closet is: the spilling water standpipe that is installed in the toilet seat water tank is arranged, the seal closure that the bottom of toilet seat water tank has the bath outlet to match, the opening chain is arranged on the seal closure, the upper end of opening chain is installed in of lever, the other end of lever connects flush button, it is characterized in that installing in the water tank push rod cylinder body, fitting piston in the cylinder body, connect piston push rod on the piston, piston push rod contacts with lever, and cylinder body has back-moving spring in the top, there is relief hole the bottom of cylinder body and is connected water inlet pipe, water inlet pipe connects the bath electromagnetic valve, and the bath electromagnetic valve connects running water pipe, and the bath electromagnetic valve is controlled by inductor.For the promotion pressure of regulating piston push rod, can in the relief hole of cylinder base, control valve be installed.Can be installed on the spilling water standpipe by fixture for cylinder body.In order to make the few water closet inwall of water amount such as direct-flushing non-caked, can connect the profit water solenoid valve simultaneously to running water pipe, the profit water solenoid valve connects the profit water pipe, and the profit water pipe connects in the spilling water standpipe, and the profit water solenoid valve is controlled by inductor.The full-automatic flushometer of this water closet utilizes induction technology (for example ripe infrared inductor that generally uses) to come control electromagnetic valve, if simple auto-flushing, only need the bath electromagnetic valve, after people use water closet, inductor is responded to back instruction bath electromagnetic valve and is worked, and the running water pipe water inlet pipe that discharges water makes the piston in the cylinder body upwards promote piston push rod, piston push rod lifts and spurs the opening chain with one on lever, seal closure is opened finished auto-flushing.After electromagnetic valve stops to discharge water, sluice through relief hole in the cylinder body, in the effect lower piston push rod decline of back-moving spring, seal closure is closed the Water flushing for cistern outlet.Whole process contacts any position without hand, automatically finishes civilization, health, environmental protection, practicality.

Description of drawings

Fig. 1 is the full-automatic flushometer organigram of the utility model water closet.

The specific embodiment

The utility model discloses the full-automatic flushometer of a kind of water closet, can be installed in the water closet of any type.Need to install two basic elements of character in the water tank 2 of water closet 1; the one, the spilling water standpipe; the 2nd, seal closure and lead agency; but concrete tectonic type kind is a lot; lead agency has nothing in common with each other; as shown in Figure 1, simple and easy spilling water standpipe 5 is installed in the water tank, the seal closure 3 that has the bath outlet to match in the bottom of water closet 1 water tank 2; be that opening chain 4 is arranged on the seal closure 3; the upper end of opening chain is installed in of lever 15, and the other end of lever connects flush button 13, in actual product; the syndeton type of lever and button is a lot; Fig. 1 is one of them, is prior art, and protection domain is not limited by accompanying drawing.This device main contents feature is that a push rod cylinder body 7 is installed in the water tank 2, in the cylinder chamber 9 of cylinder body 7 fitting piston 10 is arranged, connect piston push rod 12 on the piston 10, piston push rod 12 contacts with lever 15, cylinder body is equipped with back-moving spring 11 in 7 tops, and there is relief hole the bottom of cylinder body 7 and is connected water inlet pipe 22, and water inlet pipe 22 connects bath electromagnetic valve 20, bath electromagnetic valve 20 connects running water pipe 19, and the bath electromagnetic valve is controlled by inductor 21.When the people large and small when standing up after an action of the bowels, inductor 21 circuit workings, inductor is identical with prior art, inductor 21 instruction bath electromagnetic valves 20 are opened, the water of running water pipe 19 arrives in the cylinder bodies 7 through bath electromagnetic valve 20 and by water inlet pipe 22, and hydraulic pressure up push away piston 10 in the cylinder chamber 9, and piston push rod 12 is lifted of lever 15, the lever 15 that lifts drives opening chain 4 and seal closure 3, the bath beginning.Bath beginning backlash water solenoid valve ends, and tap water stops to import water inlet pipe, and the water in the cylinder body is through the relief hole pressure release, moves down at the effect lower piston 10 and the piston push rod 12 of back-moving spring 11, and seal closure 3 is closed the bath outlet of water tank bottom, and bath finishes.Just in case device has fault, when for example having a power failure, still can use operation such as button 13 man-operated mechanisms such as grade.The relief hole size of cylinder body 7 bottoms is influential greatly to the active force of piston push rod, is good so in relief hole control valve 6 is installed.Cylinder body 7 can be installed on the spilling water standpipe 5 by fixture 8, but also can be fixed on other position in the water tank.In order to solve the adhesion problem of water closet 1 inwall, can connect profit water solenoid valve 17 simultaneously at running water pipe 19, the profit water solenoid valve connects profit water pipe 16, and profit water pipe 16 connects in the mouth of pipe 14 of spilling water standpipe 5, and profit water solenoid valve 17 is controlled by inductor 21.When the people before stool, be subjected to effect profit water solenoid valve 17 work of inductor 21, tap water arrives in the spilling water standpipe 5 through profit water solenoid valve 17 and by profit water pipe 16, again in water closet 1, lubricated to the water closet inwall, in order to economize on water, the profit water time generally was controlled within 2 seconds, and stool just can not be bonded in the water closet inwall like this.
