Abstract

A pneumatic negative-pressure siphon closestool comprises a double-water-seal blow-off pipe, a pressure bucket is arranged in a water tank and used for producing negative-pressure siphoning, and a jet hole is omitted from the closestool, so that all flushing water flushes a closestool basin from a water ring, and the flushing effect of 8-12 liters of water of a jet siphon closestool is achieved with 4 liters of water.

Description

Pneumatic negative pressure siphonage-toilet

Art

A kind of pneumatic negative pressure siphonage-toilet, relates to field of sanitary ware.

Background technology

Negative-pressure siphoning type toilet was put invention in 2000 by China Taiyuan people engineer Liu and is come out, notification number CN2455795Y, Its advantage is a lot, and work throughout the world ought to be given ample rewards to.Its weak point is that the tank lid in technical scheme to seal, and difficulty is not Little and inconvenience is safeguarded in the future.

Summary of the invention

The present invention, for overcoming above-mentioned weak point, proposes simple, a practical technical scheme, utilizes the pressure pot in water tank Produce negative-pressure siphon, it is achieved water saving purpose.

The present invention adopts the technical scheme that: a kind of pneumatic negative pressure siphonage-toilet, and its blow-off pipe is double water seal blow-off pipes (16), Have the trachea (15) communicated in the upper end of double water seal blow-off pipes (16), trachea (15) connects on (13) at the bottom of cistern Connecing opening, as airway interface (14), there is hydrosphere (18) in toilet seat portion, has water intaking valve (1), draining in cistern Valve (9), is characterized in that；Cistern (12) is inner arranges the pressure pot (2) that a shape does not limits, in pressure pot (2) There is a dividing plate (5) that pressure pot (2) is separated into air pressure bucket (4) and draining bucket (8), air pressure bucket (4) Packed bucket Top (4-1), draining bucket (8) top is the top without bucket of open type, and the lower end bucket wall of draining bucket (8) has water inlet (11), It is possible with expanding airway and has drum head (3), wherein draining bucket (8) by hole (7) as water inlet, pressure pot (2) The drum head of part has the valve seat orifice (9-1) that can install drain valve (9), and drain valve (9) is fixed through valve seat orifice (9-1) On (13) at the bottom of water tank, air pressure bucket (4) drum head (3) has an airway corresponding to airway interface (14) to pass through Hole (7), airway (6) is connected on airway interface (14), through airway by hole (7), stands on air pressure bucket (4) in；Dividing plate (8) downwardly extends and leaves water through distance with drum head (13).

Its operation principle is: when water tank water intake, and the air in air pressure bucket is compressed in double water seal blow-off pipe；When water tank is arranged During water, in the air return in double water seal blow-off pipes to air pressure bucket, moment inhales dynamic dirt and produces siphon.

It provides the benefit that: the double water seal blow-off pipe of toilet super-large diameter, can by the spheroid not less than more than 61 millimeters, It is not easily blocked.Owing to toilet can not set the jet that injection siphonic closet is conventional, whole flushing waters, from hydrosphere douche can basin, are washed Clean effect greatly improves.

Accompanying drawing explanation

Fig. 1 is cistern schematic diagram, and Fig. 2 is toilet schematic diagram, it is illustrated that:

1, water intaking valve 2, pressure pot 3, drum head 4, air pressure bucket 4-1, bucket top

5, dividing plate 6, airway 7, airway are by hole 8, draining bucket 9, drain valve

At the bottom of 9-1, valve seat orifice 10, draining bucket wall 11, water inlet 12, water tank 13, water tank

14, airway interface 15, trachea 16, double water seal blow-off pipe 17, sewage draining exit 18, hydrosphere

Detailed description of the invention:

With reference to diagram, there is a trachea communicated on the top of the double water seal blow-off pipe of toilet, and is connected as inducing QI with at the bottom of cistern Interface tube, in order to connect airway, pressure pot is that a total measurement (volume) rises the staving between water at 2-5, and its shape is generally Ellipse, determines according to cisten mechanism, in the middle of pressure pot, above-below direction has a dividing plate being connected with bucket wall, and dividing plate is pressure pot Being separated into two parts, a part is air pressure bucket, and another part is draining bucket；Air pressure barrel section has the bucket sealed with bucket wall Top, draining bucket is without bucket top；Pressure pot has drum head, wherein arranges the valve seat orifice of drain valve, inducing QI on the drum head of draining bucket part Pipe by hole, drain valve is fixed at the bottom of water tank through valve seat orifice, the most just secures pressure pot, and airway connects with airway Mouthful couple after through airway by hole, stand in air pressure bucket, it is to be noted that airway interface is to arrange longitudinally to double water seals Dirty pipe, is arranged at the bottom of water tank so that trachea and double water seal blow-off pipes, injection forming simultaneously, is convenient to produce, therefore leads The bucket top having caused air pressure bucket is divided, and is to extend from airway sidepiece to constitute irregular type air pressure bucket, makes mold produce more complex, Also doing something against one's will, mirror is forgived in the industry, and dividing plate downwardly extends, with the distance that drum head leaves about 5-15 millimeter so that Water in draining bucket communicates with air pressure bucket, and the injection of whole pressure pot preferred mold makes.

The present invention breaches the limit of blow-off pipe diameter 56 millimeter, through experiment, has reached the super large not less than 61 millimeters Caliber, flushing water consumption is still not more than 4 liters, can reach the caliber not less than 70 millimeters in theory, toilet blocking Probability is minimum.
