Description of drawings

The utility model as shown in Figure 2, its structure mainly is made up of water tank (17), water tank (18) and lever system.Below in conjunction with accompanying drawing structure of the present utility model is described in further detail:

Fig. 1 is before the utility model is finished, the structural representation of existing toilet flushing device;

Fig. 2 is the structural representation of the utility model urinal automatic flushing device.

In Fig. 2,

The 1st, valve, the 2nd, balance weight iron, the 3rd, fulcrum, the 4th, lever, the 5th, reverse stream pipe, the 6th, struggle against against the current, the 7th, spilled water hole, the 8th, set screw, the 9th, tapping pipe, the 10th, piston, the 11st, leader, the 12nd, hand rope, the 13rd, center-pole, the 14th, lower contact, the 15th, upper contact, the 16th, electrical appliance, the 17th, water tank, the 18th, water tank.

A kind of urinal automatic flushing device, comprise fulcrum (3) and lever (4), when the gravity disequilibrium of both sides, can open or close leader (11) automatically by piston (10), one end of lever (4) has balance weight iron (2), can come adjustment by increasing and decreasing its quantity, and the other end has spilling water bucket (6), the high end of water level in the bucket, can make it move downward or upward and mention or press down piston (10) by leverage, thereby opens or close leader (11).

In technique scheme, spilled water hole (7) is arranged at the bottom of said spilling water bucket (6), and the screw (8) of regulating through-flow size is arranged on the spilled water hole (7).

Its principle is as follows:

One, open automatically: the valve (1) that is in normally open is to water tank (17) water-filling, after water fills with water tank (17), flow to spilling water bucket (6) along bleed off pipe (5), its weight is mentioned piston (10) and is opened leader (11) automatically by lever (4) and fulcrum (3) then greater than the weight of balance weight iron (2) and piston (10) combination after the water level of spilling water bucket (6) reach a certain height.The water of water tank (17) all flows into leader (11), flushing toilet bowl.

Two, close automatically: the water in the spilling water bucket (6) flows into water tank (18) from spilled water hole (7), and flows into leader (11) along tapping pipe (9).Weight saving after the water in the spilling water bucket (6) is let out certain water level, the weight of balance weight iron (2) and piston (10) combination are during greater than the weight of spilling water bucket (6), and piston (10) falls and close leader (11) automatically.

Then, the valve (1) that is in normally open continues to water tank (17) water-filling.So open, close leader (11) repeatedly automatically, thereby realize the function of automatic flushing toilet bowl.In addition, can come the weight of balance and spilling water bucket (6) and to the pressure of piston (10) by the weight of increase and decrease balance weight iron (2).And center-pole (13) can guarantee when piston (10) mention too high when falling again piston can not fall outside leader (11), too many off-centring is perhaps arranged.

Three, the time is regulated: the time that piston (10) is opened automatically can realize by the size that adjusting is in valve (1) aperture of normally open.When valve (1) when aperture is big, the time of water tank (17) filled with water shortens, the corresponding shortening of time that piston (10) is opened automatically; When valve (1) aperture hour, the time lengthening of water tank (17) filled with water, the corresponding prolongation of time that piston (10) is opened automatically.In addition, the time that piston (10) is closed after opening automatically can realize by the screw of regulating on the spilled water hole (7) (8), the screw of upwards back-outing (8), and spilled water hole (7) increases, water through-current capacity in the spilling water bucket (6) is accelerated, and the time that piston (10) is closed after opening automatically shortens; Otherwise, being screwed into screw (8) downwards, spilled water hole (7) reduces, and the water through-current capacity in the spilling water bucket (6) reduces, the corresponding prolongation of time that piston (10) is closed after opening automatically.

Four, manually opened, close: the hand rope (12) of leaving behind, hand rope (12) is mentioned piston (10) by lever (4) and fulcrum (3), just can open leader (11) to realize manual flushing.Unclamp hand rope (12), piston (10) is closed leader (11) automatically under the gravity of balance weight iron (2).

Obviously, though the utility model is that its principle, structure are equally applicable to have the place of similar applications for the automatic flushing design of urinal.As Fig. 2,, form lower contact (14) in addition if on the iron of the top of balance weight iron (2), add one section insulation wood and connect electric wire; Connect electric wire and form upper contact (15) directly over lower contact (14), when piston (10) when upwards mentioning, lower contact (14) and upper contact (15) are connected, and the composition closed circuit drives other one group of automatic regulating system.Certainly, if give up automatic washing capacity of the present utility model, get the circuit system (as Fig. 2) that its lower contact (14), upper contact (15) and electrical appliance (16) are formed, this system also has self-regulating function, can select to use for the user.
