Abstract
The utility model relates to a siphon pumping device for water tanks. An air inlet passage is arranged in the middle of the water inflow segment of a siphon pipe. Elastic plug components used for blocking the air inlet of the air inlet passage are arranged on a water lifting piston rod or a piston, and a ring structure surrounding the air inlet is arranged at the periphery of the air inlet. Thus the sealing effect of the air inlet is improved, the service life of the plug components is extended, and the failure rate of the water tank is decreased.
Description
The utility model relates to a kind of lavatory flushing water tank, especially relates to a kind of hydrocone type picotan of lavatory flushing water tank.
The siphon picotan of existing hydrocone type water lift lavatory flushing water tank comprises the outer operating mechanism of the syphon, water lift piston, piston rod and the casing that are arranged in the tank box, its operating principle is to utilize the piston water lift to form siphon, water storage in the water tank is discharged flushing toilet bowl.Easy to use, the difficult characteristics that leakage takes place that this class water tank has, its shortcoming is to change displacement, is unfavorable for using water wisely.For realizing the displacement control to such water tank, Chinese utility model patent discloses a kind of picotan No. 86205944.This picotan is provided with inlet channel at the middle part, syphon water absorbing section of original water tank siphon picotan, the rubber that is provided with the air inlet port that can stop up inlet channel on the water lift piston is stifled, realizes control to displacement by select whether to seal air inlet port in operating process.According to actual needs, if continue to lift piston rod after utilizing the piston water lift to form siphon, the stifled air inlet port with inlet channel of rubber is stopped up, then the siphon drainage process is identical when inlet channel is not set, and promptly still is full water yield draining; If after forming siphon, loosen piston rod, air inlet port is not stopped up by rubber is stifled, in the time of then under water level is reduced to air inlet port, air sucks from the air entry of inlet channel, enters syphon by air inlet port, causes siphonic process to finish, water tank stops draining, thereby realizes the draining of the part water yield.This picotan has solved the water yield control problem of hydrocone type water lift wc flushing cistern preferably, helps using water wisely, has certain advantage.In this picotan, effective shutoff of air inlet port is vital.When the full water yield draining of needs,, then can not realize the big yield flushing because of air inlet makes the siphonic process Halfway Stopping if bad sealing is close between air inlet port and the obstruction.For this reason, this picotan has adopted and has had certain flexible rubber and block up the shutoff that realizes air inlet port.But, because this device does not carry out special adaptations to the form of structure of air inlet port, and rubber gets lodged under the long period of soaking of water and in the course of work, tend to occur certain displacement, aging and distortion, thereby cause its with the contact surface of air inlet port between cooperate imprecision, shutoff air inlet port effectively produces the water tank phenomenon of cutting off the water supply midway.Therefore, one of air inlet port bad sealing fault that to be above-mentioned existing picotan very easily occur in long-term use.
The purpose of this utility model is to overcome the disadvantage that above-mentioned existing picotan exists, and provides that a kind of air inlet port sealing effect is good, the water tank siphon formula picotan of long-term work stable performance.
Picotan of the present utility model improves on the basis of existing above-mentioned picotan.In the utility model, except that admission line being set, on water lift piston rod or piston, being provided with the elasticity plug members of the air inlet port that can stop up inlet channel at middle part, siphonal water absorbing section, also the periphery of passage air inlet port be provided with the passage air inlet port surrounded and air inlet port between sealed, the circulus that is closing form in gap, this circulus matches with the obstruction face of plug members.In the utility model, above-mentioned air inlet port is surrounded and air inlet port between the sealed circulus that is closing form in gap can be intussusception in the sealed sleeve pipe in gap outside the inlet channel and between inlet channel, also can be the step ring plain with certain height difference that directly processes on the peripheral end face of air inlet port, also can also be other similar type.The circulus that is closing form can be a circle, also can be multi-turn.In the utility model; owing to be provided with the above-mentioned circulus that matches with plug members; make the elasticity plug members can be when stopping up air inlet port the airtight loop configuration that is positioned at the air inlet port periphery; can constitute simultaneously and be included in joint ring that the air inlet port place forms, prevent the multiple protective that leaks gas thereby formed at interior several sealed ring.Even because of plug members displacement, distortion or agingly shutoff occurs when tight in some block part, as long as between water tank and inlet channel, also there is a complete joint ring, can the phenomenon that water tank is out of control, cut off the water supply not appear midway because of gas leakage just, thereby can prolong the application life of elasticity plug members, lower the rate of breakdown of water tank.In general, for obtaining preferable sealing effectiveness, circulus during the utility model water lift shape is put and the contacted contact surface of plug members can omit height or a little less than the contact surface of passage air inlet port and plug members.Certainly, do not get rid of the form that is provided with that above-mentioned contact surface flushes mutually herein yet.When above-mentioned contact surface flushes mutually, can the annular recess that make it to separate be set between them, this form can obtain the better seal effect equally.Picotan of the present utility model is both applicable to high level cistern, and also applicable to low level cistern, the elasticity plug members in the picotan both can be made by rubber, also can be made by the plastics with certain elasticity and density.
Picotan of the present utility model is compared with existing similar picotan, has the air inlet good sealing effect, plug members long service life, the advantage that the water tank rate of breakdown is low.
Embodiment accompanying drawings of the present utility model is as follows.
Fig. 1 is the sectional view of water tank among the embodiment.
As shown in Figure 1, the picotan of present embodiment is a kind of picotan that is arranged at low level cistern, and this water tank is made of tank box 1, water inlet pipe 2, float valve 3 and picotan.Picotan among the embodiment comprises syphon 4, water lift piston 5, elastic caoutchouc plug members 6, piston rod 7, pull rope 8, pulley 9 and stay cord handle 10, and the delivery port 11 of syphon 4 also is the delivery port of water tank.In the picotan, elasticity plug members 6 is arranged on the piston rod 7, and an end of pull rope 8 is tied on the stay cord handle 10, and the other end is walked around the upper end that pulley 9 is tied to piston rod 7.By pulling stay cord handle 10 piston rod 7 is risen, and then water lift piston 5 and plug members 6 are risen.After loosening stay cord handle 10, piston rod 7 and piston 5, plug members 6 rely on its deadweight to fall to resetting.In the present embodiment, except that the middle part, water absorbing section at syphon 4 is provided with the inlet channel that is made of air inlet pipe 12, also be provided with on the siphon tube wall air inlet port 13 with air inlet pipe 12 surround, and air inlet port 13 between sealed, the annular step scalariform structure 14 that is closing form in gap, annular step scalariform structure 14 matches with plug members 6, make plug members 6 when air inlet port 13 is stopped up in pull-up with 14 driving fits of annular step scalariform structure, constitute compound joint ring.In the present embodiment, annular step scalariform structure 14 position of matching with plug members 6 slightly protrudes from the contact surface of air inlet port 13 and plug members 6.Corresponding with it, the obstruction face of plug members is a convex surface.
