Abstract
The utility model discloses a piston air suction type water closet, which comprises a water closet main body and a piston assembly, wherein the piston assembly consists of a piston sleeve, a piston, a spring, an end cap and a pull cable. The water closet is characterized in that the water closet main body is a siphon type water closet, the middle part of the piston sleeve is provided with a blow-off hole which is connected with a sewer, negative pressure is generated in a cavity at the front end of the piston sleeve when the piston moves backwards, and the size of the maximum air suction cavity of the piston sleeve is greater than the size of the water in the cavity at the siphon static water level of the water closet. When dirt in the water closet is flushed, the pull cable is pulled to pull the piston to move to the piston movement stopping position, the negative pressure is generated in the cavity at the front end of the piston, the dirt in the water closet is discharged into the sewer due to pressure difference, the pull cable is released after the dirt is discharged, the spring pushes the piston to reset, and the water is injected to enable the water level to reach the siphon static water level. Since the piston air suction method is adopted, the generated pressure difference is large, the problem of easiness in blockage of a siphon pipeline in the water closet is solved, and water resource is saved.
Description
Technical field
The utility model relates to a kind of lavatory pan, specifically is a kind of piston air absorbing type lavatory pan.
Background technology
Existing hydrocone type lavatory pan is in order to produce siphon effect preferably, and pipeline is less, owing to adopt natural atmosphere pressure, is easy to generate obstruction, and water level need reach siphon port upper end water level when producing siphon work, and water supply volume is bigger.
The utility model content
Problem to be solved in the utility model is, provides a kind of lavatory pan pipeline that makes to be difficult for stopping up, and water supply volume is less, the piston air absorbing type lavatory pan of rinsing well.
The technical solution of the utility model is, a kind of lavatory pan with following structure is provided, and comprises lavatory pan main body and piston component, and piston component is made up of piston bush, piston, spring, end cap, drag-line.Described piston bush and lavatory pan main body secure fit, piston and piston bush are slidingly matched, and end cap and piston bush are located by connecting, and drag-line cooperates with end cover clearance, it is characterized in that: described lavatory pan main body is siphon principle formula lavatory pan, and preceding lower end is useful on the hole slot of installation, positioning piston cover; Be useful on the mudhole that connects the effluent sewerage pipe in the middle of the described piston bush; Described spring is compression spring; There is one in the middle of the described end cap and is used for the hole that drag-line passes through; Described drag-line is for being used for the object of traction piston motion; Piston bush front end cavity produced negative pressure when described piston moved backward; The maximum inhale cavity volume of described piston bush, the volume of water in the cavity during greater than lavatory pan main body siphon static level.
After adopting above structure, the utility model compared with prior art has the following advantages:
Owing to adopt piston air-breathing, when lavatory pan siphon static level, need not add water, just the dirt under the siphon static level in the lavatory pan and sewage together can be inhaled down, enter sewer pipe, the conserve water resource.
Because use piston air-breathing, the pressure differential of generation is big, siphon piping is difficult for stopping up in the lavatory pan, has solved the greatest drawback of former siphon lavatory pan.

As shown in the figure: 1, cavity 102 when lavatory pan main body 2, piston bush 3, piston 4, spring 5, end cap 6, drag-line 101, siphon static level, locating hole 201, piston maximum inhale cavity 202, piston bush mudhole are installed
The specific embodiment
Be described further below in conjunction with the drawings and specific embodiments
When needing the dirt in the flushing lavatory pan, as shown in Figure 1, pulling drag-line (6) traction piston (3) moves to piston Mobile Termination position, as shown in Figure 2, make piston bush (2) front end cavity produce negative pressure, sewage in the lavatory pan main body (1) and dirt are because pressure differential, flow into the lavatory pan siphon piping successively, piston bush front end cavity, piston bush mudhole (202), enter sewer pipe, wait for sewage, dirt unclamps drag-line (6) after draining only, promotes piston (3) by spring (4) and resets, the water that reinjects makes the water level in the lavatory pan main body (1) reach the siphon static level, as shown in Figure 1.
Claims (1)
