Field of the Invention [0001] The present invention relates to a toilet flushing apparatus, and more particularly, to a toilet flushing apparatus for flushing a toilet seat when a user seated on a toilet seat inflows into a cylinder discharging air out of the seat, The water draining operation of the toilet can be performed by opening the drain hole by the operation of filling air into the toilet seat discharged from the cylinder so that the user can easily lower the toilet seat water without using the hand.

Generally, when the lever is rotated by operating the handle, a lift wire suspendably connected to the lever pulls a flapper above the tank to open the drain of the tank, thereby cleaning the toilet body.

The toilet water dropping device having the above-described cleaning function includes a tank in which water is stored, a body in which the toilet seat on which the toilet user sits is rotated, a body in which the water in the tank is discharged and the toilet is washed, A flapper that opens or closes the drain hole so that the tank is filled with water, a lever that is connected to the lifting rope so as to raise the flapper and that is lifted up and down by the handle, a handle provided outside the tank to operate the lever, And a water supply unit for supplying water to the tank after the drain hole is closed.

When the lever is rotated upward by operating the grasper provided in the tank, the lift string connected to the flap pulls the flapper upward in accordance with the upward rotation of the lever, and the flapper is rotated by the upward pulling The drain hole is opened, and the water of the tank flows to the main body through the drain hole by opening the drain hole, thereby washing the main body of the main body.

As the water in the tank is discharged to the main body, the flapper is pivoted downward as the water level in the tank is lowered. When the drainage of the water is completed, the flapper is completely dropped into the drain hole by gravity to seal the drain hole. Thereafter, water is supplied into the tank by the operation of the water supply unit, and when the water supplied into the tank reaches a predetermined height, the operation of the water supply unit is stopped and the supply of water is automatically shut off.

An example of a conventional flapper and automatic flushing device for a toilet using a littler string is illustrated in FIG. 1 is disclosed in Korean Patent Publication (A) No. 10-2012-0084475 (published on July 30, 2012) as a " non-electric water channel opening / ). The toilet seat (1) is provided with a water drop valve (2) and a water discharge section (3). When the user places the toilet seat 1 on the toilet seat 1, the water channel is opened by the load of the user and water is supplied and stored from the water shower. When the user comes to the toilet seat 1, And serves to supply the water of the water-conducting portion to the water-dropping portion 3 when the water is discharged.

The water dropping section 4 opens the drain port by upwardly rotating the siphon cover 5 while expanding the expansion member (not shown) by the water pressure of the water supplied from the water drop valve 2, And discharges the waste water.

Reference numeral 6 denotes a toilet body; 7 denotes a handle for operating the siphon cover 5; 8 denotes a lever and a siphon cover 5 which are rotated by the handle 7 to open the siphon cover 5; And 9 is a tank for storing washing water.

A part of the water stored in the storage space of the water drop valve 2 is introduced into the inflow hole of the water discharge section 3 when the user sits on the toilet seat 1, Is in a closed state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

The toilet water dropping device of the present invention is provided with a cylinder 40 on a lift wire 14 so as to turn the flapper 13 upward. The upper portion of the cylinder 40 is suspended in the lift line 14 and the piston rod 43 which is moved upward and downward by the piston 42 in the cylinder 40 is also supported by a lift line 14) are connected.

The toilet seat constituting the toilet flushing water dropping device of the present invention is constituted by a toilet seat 20 having an empty hollow portion 22 inside.

The toilet seat 20 serves to generate compressed air to operate the cylinder 40 when the hollow portion 22 is pressed and deformed by a load of the user and returns to its original state due to no load applied by the user And serves to discharge air from the cylinder 40 when the cylinder 40 is opened.

The cylinder 40 is also provided with a spring 44 on the piston rod 43 to assist in moving the piston 42 upwardly of the cylinder 40 and to open the flapper 13.

The toilet seat 20 is formed with an air inflow orifice 24 so that the compressed air can be discharged to the outside or introduced from the outside. Similarly, the cylinder 40 also has an inlet / outlet hole 46 so that the compressed air for moving the piston 42 is introduced or discharged from the outside.

The inflow hole 24 of the toilet seat 20 and the inflow hole 46 of the cylinder 40 are connected to the connection pipe 30 so that compressed air flows.

Reference numeral 12 denotes a handle provided outside the tank 11. Reference numeral 16 denotes a lever which is pivotally moved by a handle and connected to the lift rope 14 so as to suspend and open the flapper 13. [

The toilet seat lifting device of the present invention having the above structure can prevent the toilet seat 20 from being pushed and deformed by the load when the toilet seat 20 is seated in the toilet seat 20, And is moved to the coupling pipe 30 through the inlet / outlet hole 22 of the toilet seat 20.

The air moved to the connecting pipe 30 flows into the cylinder through the inflow hole 46 of the cylinder 40 and the piston 42 is moved to the lower portion of the cylinder 40 by the introduced compressed air, The spring 44 provided on the rod 43 is also compressed.

When the user of the toilet seat 20 subsequently emerges from the toilet seat 20, the force acting on the toilet seat 20 is released, and the force pressing the piston 42 is also weakened.

When the toilet seat 20 is restored to its original state, the force pressing the hollow portion 22 is released, and the compressed air is quickly returned from the cylinder 40. Simultaneously, the piston 42 is quickly moved to the upper side of the cylinder 40 by the repulsive force of the spring 44 provided on the piston rod 43.

At this time, when the spring 44 is released from the force in the compressed state and is returned to the original state, the spring 44 is repelled more greatly than the position of the equilibrium state by the elastic force of the spring, And then comes to its original position.

The piston rod 43 is moved upward by the repulsive force of the spring 44 and the pressure released in the cylinder 40 so that the lift rod 14 connected to the piston rod 43 is pulled upward to the tank, The flapper 13 connected to the flapper 13 is rotated upward to open the drain port 15 so that the water flows to the toilet body 10 through the drain port 15 and the bowl and the urine of the toilet body 10 are cleaned.

When the discharge of the water to the drain 15 of the tank 11 is completed, the flapper 13 which has been turned upward is dropped downward by the gravity so that the drain 15 is hermetically sealed, Water is supplied.

The present invention can also be used in a manner that the flapper 13 is opened by operating the knob 12 as in the prior art.

Another embodiment of the present invention is shown in Fig. This embodiment is provided with an auxiliary buoyancy sump 50 to reduce the force exerted on the lift string 14 by weight on the cylinder 40 suspended in the tank 11.

The auxiliary buoyancy port 50 is connected to the body of the cylinder 40 by the line 52 of the auxiliary buoyant sulcus and floats on the water surface in the tank 11, ) In the direction of the arrow.

When the compressed air flows into the cylinder 40 from the toilet seat 20 or when the piston 42 of the cylinder 40 is moved upward and the compressed air is discharged from the cylinder 40, It serves to reduce the force acting.

When the water level in the tank 11 is discharged through the drain port 15, the auxiliary buoyancy port 5 is also lowered along the water surface. When the water level rises, the buoyant surface is floated on the water surface again, The force acting on the cylinder 40 is reduced.

This embodiment is the same as the toilet water dropping apparatus of Figs. 2 to 5 except for the auxiliary buoyancy valve 50, so a detailed description thereof will be omitted.

The present invention can be used alone or in combination with a cylinder on a lift line to a toilet flushing water reducing apparatus using a flapper.
