Abstract

The utility model discloses an automatic flushing device for a public lavatory, which is composed of a water drain valve, a downflow pipe, a water inlet, an overflow water pipe, an auxiliary water tank, a siphon water drain pipe, a main water tank and a ball float connecting rod. The utility model is characterized in that the siphon water drain pipe is arranged on the central line of the water tank and fixed on the bottom face of the main water tank; a ball float is connected with the water drain valve via the connecting rod, the downflow pipe and the overflow are symmetrically arranged on the bottom face of the auxiliary water tank, and the water drain valve is tightly covered on the mouth of the downflow pipe. The utility model has the advantages of reasonable structure and design, safe operation, low possibility of damage, reasonable use of water and water saving; the expenses of maintenance and repair are reduced, and use cost is reduced.

Description

A kind of public lavatory auto-flusher

Technical field

The utility model belongs to technical field of sanitary ware, relates in particular to a kind of public lavatory auto-flusher.

Background technology

At present, known public lavatory auto-flusher is mainly by storage tank, gutter, with compositions such as automatic drain valves, when storage tank storage full water, make the siphoning installation of draining valve inside produce siphonage, form vacuum, the rubber of actinal surface upwards picks up on the gutter covering, and opens the draining mouth of pipe, water in the water tank is excreted in the urinal, and siphonal effect is to be to open gutter rubber suitable for reading and valve.Its shortcoming is that the rubber skin is closed or the valve core of opening water discharge pipe, because of frequent unlatching, close very fast aging damage of rubber skin, make the draining mouth of pipe occur leaking, out of control, the cisco unity malfunction of device causes washing by water, a large amount of tap water are run off, need carry out regular maintenance work.

Summary of the invention

The utility model purpose overcomes the prior art shortcoming, and a kind of public lavatory auto-flusher is provided.It is to utilize the safe and reliable auto-flusher of the direct draining of syphon, to reach using water wisely, reduces the maintenance and repair expense, reduces the purpose of use cost.

The utility model is achieved by the following technical solution: this bath device is made up of water discharging valve, sewer pipe, water inlet, overflow pipe, secondary water tank, siphon drainage pipe, main water box, floating ball rod.Siphon drainage pipe is installed on tank center's line, and it is fixed on the main water box bottom surface, and ball float links to each other in water discharging valve by connecting rod, and on the bottom surface that is installed in secondary water tank of sewer pipe and overflow pipe symmetry, water discharging valve tightly covers on the sewer pipe mouth.

Its beneficial effect is: since adopt technique scheme can make the utility model structure, reasonable in design, running is safe and reliable, not fragile, reasonable use of water, using water wisely, minimizing maintenance and repair expense, the use cost that reduces.

Description of drawings:

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Accompanying drawing is a structural representation of the present utility model.

Among the figure: 1. water discharging valve, 2. sewer pipe, 3. water inlet, 4. overflow pipe, 5. secondary water tank, 6. siphon drainage pipe, 7. main water box, 8. floating ball rod.

The specific embodiment

In the drawings, the utility model is made up of water discharging valve (1), sewer pipe (2), water inlet (3), overflow pipe (4), secondary water tank (5), siphon drainage pipe (6), main water box (7), floating ball rod (8).Siphon drainage pipe (6) is installed on tank center's line, and it is fixed on main water box (7) bottom surface, ball float links to each other in water discharging valve (1) by connecting rod (8), on the bottom surface that is installed in secondary water tank (5) of sewer pipe (2) and overflow pipe (4) symmetry, water discharging valve (1) tightly covers on sewer pipe mouth (2).The effect of siphon drainage pipe (6) is directly the water in the water tank to be discharged fast.

Its operating principle is: tap water at first flows into secondary water tank, when the water level of secondary water tank is higher than the overflow pipe mouth of pipe, the water that flows into secondary water tank flows to main water box by the overflow pipe mouth of pipe, make the water level of main water box slowly be elevated to the siphon drainage mouth of pipe and flow to main water box, when making the main water box water level slowly be elevated to the lower edge of siphon drainage pipe sweep, the ball float come-up, drivening rod rises, make the water in the secondary water tank flow into main water box rapidly, the main water box water level slowly raises, the siphon drainage pipe top is flooded, discharge the air in the siphon drainage pipe, make the suction water pipe begin suction automatically and just the water in the main water box is all poured urinal rapidly, discharging quantity of water and bath time can be designed as required voluntarily, are controlled by water intake velocity and water tank size.

The effect of secondary water tank is when the water level of main water box slowly is elevated to the lower edge of siphon drainage pipe sweep, water level just can't raise, siphon drainage pipe just can not be worked, and at this moment secondary water tank supplies water rapidly, floods syphon top siphon drainage pipe and could absorb water siphonage takes place.

Claims

1, a kind of public lavatory auto-flusher, it is made up of water discharging valve (1), sewer pipe (2), water inlet (3), overflow pipe (4), secondary water tank (5), siphon drainage pipe (6), main water box (7), floating ball rod (8); It is characterized in that: siphon drainage pipe is installed on tank center's line, and it is fixed on the main water box bottom surface, ball float links to each other in water discharging valve by connecting rod, and on the bottom surface that is installed in secondary water tank of sewer pipe and overflow pipe symmetry, water discharging valve tightly covers on the sewer pipe mouth.

2, public lavatory according to claim 1 auto-flusher, it is characterized in that: siphon drainage pipe is to make with plastic pipe.
