Abstract
A water-saving pneumatic flushing cistern for toilet features that a water seal is formed at lower end of siphon tube and the water level in cistern is higher than top end of siphon tube, so that siphon action is inactive as the air in siphon tube is sealed by water, and water in cistern does not drain. An air tube connected to switch is installed to top end of siphon tube. Operating switch can control the siphon action. The quantity of drained water can be concrolled by three levels, so saving water. Said switch can be operated by pedal.
Description
The present invention relates to the wc flushing cistern of a kind of washroom lavatory pan.
The seepy question of wc flushing cistern has become a long-term puzzlement people's a difficult problem, has pass department and introduces, and the water yield that China loses because of radiator leak every year reaches about 6 billion cubic meters.In order to prevent radiator leak, the someone has invented siphon water tank.In known siphon water tank, siphonal top always exceeds the water surface, when needing flushing, floods by other device, floods syphon (or the water level in the raising syphon), thereby produces siphon.Though this method can prevent radiator leak, bring certain difficulty also for the generation of siphon.Therefore, siphon water tank mostly is used for high level cistern.Up to the present, no matter be that a kind of wc flushing cistern all exists two common weakness, the one, water yield can not be controlled, and is unfavorable for water saving; The 2nd, manual control, promptly inconvenient, keep away the cross-infection that unavoidable hand contact tank switch brings again.
Along with Increase of population, water resource is more and more valuable, the using water wisely problem that become international.Purpose of the present invention just provides a kind of leakproof, and fault is few, can arbitrarily control the water-saving wc flushing cistern of water yield.Another object of the present invention is to satisfy the hygienic requirements of the foot-operated control of public place wc flushing cistern, the cross-infection of avoiding hand contact tank switch to bring.
The present invention is through test of many times and actual the use, and not only proof has tangible water-saving result, and foot-operated control is that health is convenient again.
The present invention is by water tank, float valve, syphon, switch and tracheae are formed, it is characterized in that syphon is after repeatedly bending up and down (being similar to the syphon series connection), form a water seal in the bottom, and allow the water level in the water tank be higher than siphonal top, at this moment the air between bottom and the top, water sucking mouth is blocked in the pipe by water seal in syphon, so can not form siphon, be that water tank can not leak yet, on top, siphonal water sucking mouth, a tracheae is installed, tracheae is connected with the switch that the control air is discharged or sucked, control the discharge or the suction of siphon air in tube by the keying of switch, thereby make syphon produce siphon automatically or end the water outlet of siphon control water tank or cut off the water.
Explanation and accompanying drawing from a kind of embodiment is further explained below:
Fig. 1 is a generalized section of the present invention.
As shown in Figure 1, water tank (1), float valve (4), syphon (3), tracheae (5), switch (10), feed pipe (2), the water-saving type gas controlled washing water tank that water injection pipe (9) and delivery port (8) are formed, its operating principle is, syphon (3) is after bending repeatedly, (c) forms a water seal in the bottom, the top (a) of syphon (3) and (b) all be lower than water water level (12) in the water tank, tracheae (5) also is installed on the top (a), tracheae (5) is connected with switch (10), water in the feed pipe (2) enters water tank (1) through float valve (4) and water injection pipe (9), when the water level in the water tank (1) raises, water level in the syphon (3) also increases, when water level is crossed top (a), can form water seal in the bottom of syphon (3) (c), air between top (a) and bottom (c) is sealed up for safekeeping in pipe, further rising along with water tank (1) middle water level, the water that enters bottom (c) through syphon (3) top (a) also constantly increases, the also corresponding rising of the pressure that air is subjected to, according to physics principle, the pressure of the interior top of syphon (3) (a) and bottom (c) equates, can be pressed towards top (b) along with the rising of air pressure so enter the water of bottom (c), when water level during near top (b), water in the water tank floods syphon (3) fully, reach the water level (12) of regulation, float valve (4) is closed automatically, and the injecting process of water-saving type gas controlled washing water tank finishes.
The flushing process of water-saving type gas controlled washing water tank is divided into three kinds of modes:
One. big yield (whole box water) flushing, its operating principle is, open and close a switch (10), unclamp again after promptly pressing the button (13), the air in the syphon (3) is pushed by water, discharge from switch (10) by tracheae (5), syphon (3) produces siphon automatically, and the water level in water tank (1) is lower than syphon (3) water inlet, after air reenters syphon (3), siphon just stops, and flushing process finishes.
Two. the little water yield (about smaller part case water) flushing, its operating principle is, open switch (10), do not unclamp after promptly pressing the button (13), the air in the syphon (3) is pushed by water, discharge from switch (10) by tracheae (5), syphon (3) produces siphon automatically, and when the water level in the water tank (1) was lower than the top (a) of syphon (3), air reentered syphon (3) by switch (10) and tracheae (5), siphon stops, and flushing process finishes.
Three. middle water yield flushing, its operating principle is, opens and closes a switch (10), unclamps again after promptly pressing the button (13), air in the syphon (3) is pushed by water, discharge from switch (10) by tracheae (5), syphon (3) produces siphon automatically, after lavatory pan reaches developing result, open switch (10) once more, promptly press the button (13) and allow air pass through switch (10) and tracheae (5) reenters syphon (3), end siphon, flushing process is finished.
The tracheae of this water-saving type gas controlled washing water tank (5) length can suitably extend as required.Therefore, switch (10) promptly can be installed in any position on the water tank, manually control; Can be installed on the ground foot-operated control again.
Air inlet pipe (7) also is housed on the float valve (4), and its function is to prevent that the water in the water tank (1) is inhaled into feed pipe (2) and replenishes air in water injection pipe (9).The water outlet direction of water injection pipe (9) in the process of water filling, allows an amount of air inject syphon (3) facing to the water sucking mouth of syphon (3), guarantees to have in the syphon (3) enough air to be sealed up for safekeeping between top (a) and bottom (c).
Ball float height regulating rod (11) on the float valve (4) is used for regulating the height of water level (12).
Certain distance that staggers between delivery port (8) and the syphon (3) helps improving siphon effect.If on the water inlet of lavatory pan, water seal is set, delivery port (8) is fallen at the end, can improve siphon effect equally.
The delivery port of this water-saving type gas controlled washing water tank (8) does not need sealing, does not need bleed off pipe, thus simple in structure, leakproof.Can not only be used for the flushing of various new-type lavatory pans and other sanitary installation, but also can be used for the transformation of old-fashioned lavatory pan wc flushing cistern, i.e. water-saving health again, social benefit is very good.
Claims (2)
1. one kind by water tank (1), float valve (4), syphon (3), the water-saving type gas controlled washing water tank that tracheae (5) and switch (10) are formed is characterized in that, syphon (3) is through up and down repeatedly after the bending, (c) forms a water seal in the bottom, water level (12) in the water tank (1) is higher than the top (a) of syphon (3) and (b), air between the interior bottom of syphon (3) (c) and top, water sucking mouth (a) is blocked in the pipe by water seal, the top (a) of syphon (3) water sucking mouth is equipped with a tracheae (5), tracheae (5) is connected with switch (10), control the discharge or the suction of air in the syphon (3) by the keying of switch (10), make syphon (3) produce siphon automatically or end siphon, thus the water outlet of control water-saving type gas controlled washing water tank or cut off the water.
