Detailed Description
The technical solution of the present invention is further described below by means of specific examples.
As shown in fig. 1 and 2, the water-saving squatting pan of the present embodiment includes a squatting pan 1, a flushing tank 4 and a water storage tank 5, a flushing pipe 10 is disposed on one side of the squatting pan 1, a pedal 2 and a compressible water tank 3 are disposed on the periphery of the squatting pan 1, the pedal 2 is fixedly disposed on the top of the compressible water tank 3, an elastic element 31 is disposed in the compressible water tank 3, the elastic element 31 is supported between the top and the bottom of the compressible water tank 3, the compressible water tank 3 is pressurized to discharge water, and water is absorbed from the water storage tank 5 through a second connecting pipe 12 due to the restoring force of the elastic element 31 and is restored to the original volume. Preferably, the lowest pressed surface of the pedal 2 is higher than the upper surface of the squatting pan 1 so as to meet the height requirement of the squatting pan and avoid the influence of too low pedal on the toilet effect. The pedal and the compressible water tank can be fixed above the periphery of the existing squatting pan, and can also be produced by a squatting pan manufacturer and the squatting pan at the same time. Meanwhile, the upper surface of the pedal is provided with an anti-slip structure to prevent a user from slipping.
As can be seen from fig. 3 and 4, the flush tank 4 of the present embodiment is communicated with the compressible tank 3 and the flush pipe 10 by a three-way valve 7, the three-way valve 7 includes a first orifice 71, a second orifice 72, a third orifice 73 and a plunger 74, the first orifice 71 is connected to the outlet of the regulating valve 6, the second orifice 72 is connected to the flush tank 4, and the third orifice 73 is connected to the flush pipe 10; the plunger 74 of the three-way valve 7 is movably arranged between the first pipe orifice 71 and the third pipe orifice 73 through a spring 75 and an adjusting core 76, the spring 75 is arranged between the plunger 74 and the adjusting core 76, and the adjusting core 76 is used for adjusting the elastic coefficient of the spring.
In a conventional state, when the pedal 2 is not pressed, namely no one steps on the pedal, the plunger 74 is blocked between the first pipe orifice 71 and the second pipe orifice 72, the second pipe orifice 72 is communicated with the third pipe orifice 73, namely the flushing tank 4 is communicated with the flushing pipe 10; when the pedal is pressed, namely a person steps on the pedal 2, the plunger 74 is forced to be blocked between the second pipe orifice 72 and the third pipe orifice 73, the plunger moves from a point a to a point b in the figure, the first pipe orifice 71 is communicated with the second pipe orifice 72, the compressed water tank 3 is communicated with the flushing water tank 4 through the first connecting pipe 11, the regulating valve 6 and the third connecting pipe 13, and water in the compressed water tank 3 enters the flushing water tank 4; when a person leaves the pedal, the plunger 74 moves upwards under the restoring force of the elastic element 31 in the compressible water tank 3, the flushing water tank is communicated with the flushing pipe, and water in the flushing water tank enters the squatting pit through the flushing pipe to flush dirt in the squatting pit.
In this embodiment, for guaranteeing the water in the flushing tank sufficient, storage water tank 5 also can be through second connecting pipe 12, governing valve 6 and three-way valve 7 and flushing tank 4 intercommunication, and when footboard 2 was pressed, in the water in storage water tank 5 and the water in the compressible water tank 5 flowed into flushing tank 4 jointly for the water yield in the flushing tank 4 is sufficient, is enough to wash the filth in the squatting pot.
The regulating valve 6 can regulate the amount of water per unit of time that enters the flushing tank 4 from the compressible tank 3. Preferably, the opening of the regulating valve 6 is adjusted according to the opening of the throttle installed in the toilet for men and women. Such as: when the device is installed in a man toilet, the opening degree of the adjusting valve 6 can be adjusted to 50 ml/s, so that if the pedal is stepped for 5 minutes during defecation, the device can enter the flushing tank from the compressible water tank for 15 liters at most, and the flushing amount can also reach 15 liters. If the pedal is depressed for 1 minute while urinating, the flush volume is 3 liters. If the toilet is installed in a female toilet, the opening degree of the adjusting valve 6 can be adjusted to 30 ml/s, so that if the pedal is stepped for 5 minutes during defecation, the compressible water tank can enter the flushing tank for 9 liters at most, and the flushing amount can also reach 9 liters. If the pedal is depressed for 2 minutes, the flush volume is 3 liters.
A piston 41 and an elastic push rod 42 are arranged in the flushing tank 4, the elastic push rod 42 is pressed when water enters the flushing tank, and the elastic push rod 42 is used for pressurizing and discharging water on the other side of the piston 41 during drainage, so that the water flushed by the flushing tank has pressure to flush away dirt in a squatting pot.
A check valve 8 is arranged between the water storage tank 5 and the compressible water tank 3 to prevent water in the compressible water tank 3 from flowing back to the water storage tank 5, so that unidirectional flow of water is ensured.
The storage water tank 5 is also communicated with the flushing pipe 10 through a standby connecting pipe 14, the standby connecting pipe 14 is provided with a manual flushing valve 9, so that the squatting pan needs to be flushed when no person steps on the pedal, the manual flushing valve 9 is opened, water in the storage water tank 5 can flush dirt in the squatting pan, and normal use of the squatting pan is guaranteed.
Meanwhile, the water storage tank 5 is a non-pressure water tank, and the height difference between the water storage tank and the flushing tank 4 is within 2 meters. The water storage tank is prevented from being too high, the water outlet pressure is too high, and water directly enters the flushing tank; or prevent the reservoir from being positioned too low, resulting in the compressible tank failing to suck water.
To avoid discomfort caused by the pedal falling too much. The compressible water tank can be replaced by water tanks with different descending heights or different sizes, and the volume is the maximum water quantity which can enter the flushing tank and is also the maximum flushing water quantity of the squatting pan. Such as: the total volume can be selected to be about 12 liters, the height of the cross section is 5 centimeters, the width of the cross section is 17 centimeters, and the length of the water tank along the squatting pan is 1.4 meters; or the total volume is about 12 liters, the height of the cross section is 4 centimeters, the width of the cross section is 22 centimeters, and the length of the water tank along the squatting pan is 1.4 meters; the total volume can be about 10 liters, the height of the cross section is 5 centimeters, the width of the cross section is 14 centimeters, and the length of the water tank along the squatting pan is 1.4 meters; and similarly, various specification alternatives can be made.
When the water-saving squatting pan is adopted, people step on the pedal, water in the compressible water tank continuously enters the flushing tank, the longer the pedal is pressed, the more the water in the flushing tank is, and when a user leaves the pedal, the water is flushed into the squatting pan from the flushing tank so as to remove dirt. From this, can realize mechanical control big or small water washing according to footboard pressurized time, simple structure, convenient operation, the water conservation effect is better, possesses great marketing potentiality.
While the embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that variations may be made in the embodiments without departing from the spirit of the invention, and such variations are to be considered within the scope of the invention.
