Toilet flushing device

The present invention

The present invention relates to a toilet flushing device, and more particularly, to a toilet flushing device for automatically draining even after the user does not operate the flushing lever.

Most toilets are equipped with flush toilets, and after flushing the toilet, press the flush lever to supply the water stored in the tank to the toilet to discharge the waste in the toilet to the sewer.

However, the problem of the conventional flush toilet is that the user often forgets to press the flush lever after the toilet as everyone experienced once or twice in a public toilet, which caused severe discomfort to the next user and caused the inside of the toilet to vibrate as a bad smell by drainage. It became.

In order to solve this problem, recently, an electronic sensing sensor has been installed in a toilet to detect when a user approaches the toilet seat, and a water purifier has been developed to supply water to the toilet by operating when the toilet seat is a predetermined distance away.

However, such a conventional water washing device is a waste of water because it is operated and drained only by passing near the toilet without looking at the toilet, and since the power and electronic parts are used, breakdowns are frequently caused by damage to the parts due to overcurrent. There was a problem such as an increase in the installation cost due to the electronic components of the electronic components, do not work during power failure.

In order to solve this problem, a flushing device has been developed to operate when water rises after sitting on the toilet seat, which supplies water to the toilet. Since the water is supplied and drained, it has to be drained again after complete aftertreatment.

An object of the present invention for solving the above-mentioned problems is to provide a toilet flushing device so that water is supplied to the toilet and drained after a predetermined time delay when sitting on the toilet seat.

The toilet flushing device according to the present invention for achieving the above object is a check valve installed on one side lower end of the tank to supply water in the tank to the toilet, a wash lever installed outside the tank to open and close the check valve, and water storage in the tank. In a flushing device for a toilet having an opening and closing lever to rotate about one side to open and close a water supply valve according to a state, a pressurizing chamber is formed inside, and an air inlet is formed at one side, so that the air inside the pressurizing chamber is compressed. A toilet seat which is quickly discharged and the air discharged upon decompression is slowly introduced into the pressure chamber; A pivoting lever hinged to pivot in a vertical direction in the through hole formed at one end of the opening and closing lever; An operating lever installed at an upper part of the opening / closing lever so as to move forward and backward by pneumatic pressure entering and exiting the toilet seat, and pushing or pulling the upper end of the rotation lever when moving back and forth; A guide rod having an upper end fixed to one end of the opening and closing lever and extended to the lower side; A guide hole is formed at a position eccentrically to one side from the center of the cylinder and is coupled to the guide rod, and an incision groove is formed at one side so that the upper portion is rotated to one side about the lower end, and the check valve when lifted by the amount of water in the tank Characterized in that consisting of a float for opening and closing the.

According to another aspect of the present invention, a toilet flushing device includes a check valve installed in a toilet seat between an air inlet and a pressurizing chamber to discharge air in the pressurizing chamber, and a small amount of air provided between the air inlet on one side of the check valve and the pressurizing chamber. Auxiliary valves are installed to move in and out, and when the user stands up from the toilet seat, air is slowly introduced through the auxiliary valves to delay the opening of the check valve.

Another feature of the flushing device for toilet according to the present invention, on the lower side of the float, the weight is provided so that the guide hole inner surface of the float in close contact with the guide rod.

Therefore, when standing up from the toilet seat after the toilet, the corrugated pipe and the compressed toilet seat are restored, and air is slowly introduced through the narrow air inlet passage of the auxiliary valve, so the time is delayed until the check valve is opened. Even if only a little occurs in the water is immediately supplied to the toilet to solve the conventional problem of draining the water again in the final treatment, there is an effect such as saving water.

Specific features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings.

In Figure 1, the toilet flushing device of the present invention is provided with a check valve (4) at one side lower end of the tank to supply water in the tank to the toilet (1), the auxiliary strap to open and close the check valve (4) outside the tank ( 3) The well-known water lever 2 is connected, and the water opening and closing lever 19 is installed in the water tank so as to rotate about one side in the water storage state in the water tank to open and close the water supply valve 20. have.

And the coupling lever 21 is formed at the end of the opening and closing lever 19, the pivoting lever 24 to be described later is hinged thereto.

On the other hand, the toilet seat (5) is provided with a pressurized chamber (7) in the interior, the bellows portion (6) is provided on the periphery and the air inlet (8) is provided on one side.

A check valve 9 is provided between the air inlet 8 and the pressurizing chamber 7 so that the air in the pressurizing chamber 7 is quickly discharged through the outlet 10 and the discharged air is not flowed back. 9) An auxiliary valve 11 is installed between the air inlet 8 on one side and the pressure chamber 7 so that a small amount of air enters and exits.

The auxiliary valve 11 has a relatively narrow air inlet passage 12 connecting the pressure chamber 7 and the air inlet 8, a coupling band 13 surrounding the outer circumference of the air inlet passage 12, and a coupling band. Composed of a tightening screw 14 to tighten or extend (13), by rotating the tightening screw 14 it is possible to change the diameter of the air entry passage 12 of the rubber material by the coupling band (13).

Here, the auxiliary valve 11 may be configured as described above, but may be any structure as long as the auxiliary valve 11 can adjust the amount of air introduced into the pressure chamber 7 from the air inlet 8.

The check valve 9 and the auxiliary valve 11 of the toilet seat 5 have a slow inflow of air through the auxiliary valve 11 when the user stands up from the toilet seat 5 so that the check valve 4 in the water tank is opened. This will delay the timing.

On the other hand, the rotation lever 24 is engaged with the hinge pin 23 so as to rotate in the vertical direction in one end of the opening and closing lever 19, the guide 22 is provided on the opening and closing lever 19, The operating lever 17 is coupled to the guide.

The operation lever 17 is provided with a hook portion 18 at one end, that is, the end of the rotation lever 24, and pushes or pulls the upper end of the rotation lever 24 at the time of forward and backward advance, and the other end of the rotation lever 24 A corrugated pipe 16 is connected, and a connecting pipe 15 is connected between the corrugated pipe 16 and the air inlet 8 of the toilet seat 5 to allow pneumatic pipes to enter and exit the inside of the toilet seat 5. 16).

On the other hand, one end of the opening and closing lever 19 is fixed to the upper end of the guide rod 25 is extended to the lower side, the float 26 is coupled to the guide rod 25 to be elevated along this.

The float 26 is formed with a guide hole 27 at a position eccentrically to one side from the center of the cylinder, the incision groove on one side of the guide hole 27 so that the upper portion of the float 26 is rotated to one side around the lower end 28 is formed, and the weight 26 is provided in the float 26 below the incision groove 28.

The weight (29) is to support the inner surface of the guide hole (27) of the float 26 in close contact with the guide rod 25, the weight (29) and the check valve (4) is connected to the tie (30) It is connected.

Here, the length of the connecting strap 30 is equal to the distance between the bottom of the float 26 and the top of the check valve 4 when the upper end of the float 26 is supported at the end of the open / close lever 19, and thus the float 26 ) Rises upward from the end of the opening / closing lever 19 and the connecting string 30 is pulled to open the check valve 4.

The operation of the toilet flushing device of the present invention in this configuration is as follows.

1 or 2 is a state in which the float 26 is lowered, and this state is a state in which water is drained from the water tank to the toilet 1. As shown in the related art, the water supply valve 20 is opened by the opening / closing lever 19. Open the water supply state into the tank.

In this way, as the water in the tank gradually rises, the float 26 rises and pushes up the end of the opening / closing lever 19. As a result, the water supply valve 20 is blocked, so that the water supply is stopped.

In this state, when the user sits on the toilet seat 5, the pressure chamber 7 of the toilet seat 5 is strongly pressed by the weight of the body, and the air inside the pressure chamber 7 of the auxiliary valve 11 A small amount is discharged through the air inlet passage 12, but is mostly discharged to the air inlet 8 through the outlet 10 of the check valve 9 opened by pneumatic pressure.

Pneumatic pressure passing through the air inlet (8) is supplied to the corrugated pipe (16) through the connecting pipe (15) to increase the length, accordingly the operating lever (17) is advanced to the top of the rotary lever 24 as shown in FIG. Push to pass.

When the user stands up from the toilet seat 5, the bellows portion 6 and the corrugated pipe 16 of the toilet seat 5 is restored and air is introduced into the pressure chamber 7 through the connecting pipe 15 again.

Here, when air flows into the pressure chamber 7, the check valve 9 is closed as shown in FIG. 8, so that all the air is introduced through the air inlet passage 12 of the auxiliary valve 11.

Therefore, the air in the corrugated pipe 16 is gradually introduced into the pressure chamber 7 through the narrow air access passage 12, so that the predetermined time is required for the operating lever 17 to be reversed as shown in FIG. Delay.

As the operation lever 17 is slowly retracted as described above, when the hook portion 18 is caught on the top of the rotation lever 24 and pulled, the upper portion of the float 26 is removed as shown in FIG. It is released from the opening and closing lever 19 end.

In this way, the float 26 floats upwards by the water stored in the water tank and pulls the connecting string 30 so that the check valve 4 is opened. Accordingly, the water in the water tank is supplied to the toilet 1 and the toilet ( It is discharged to the sewer with the dirt of 1).

Here, the time until the operation lever 17 in the advanced state as shown in FIG. 5 is hung on the upper end of the pivoting lever 24 as shown in FIG. 6 and pulled is the pressure chamber 7 through the air access passage 12. Since the water is proportional to the time that the air is introduced into the inside of the toilet seat (5) for a while, the water in the tank is not immediately supplied into the toilet (1).

This delay time, that is, the time the water in the tank is supplied to the toilet can be adjusted by the auxiliary valve 11, by tightening or increasing the coupling band 13 by rotating the tightening screw 14 of the auxiliary valve 11 rubber Since the diameter of the air access passage 12 of the ash is reduced or increased, the amount of air introduced can be adjusted.

Usually, if you get out of the toilet seat (5) for a while, such as taking out a toilet paper or lifting a newspaper on the floor, and then sit back, the delay time should be about 5 seconds so that the water in the tank is not supplied to the toilet. If it fully occurs, after 5 seconds, the hook portion 18 of the operating lever 17 pulls the upper end of the rotation lever 24 so that the float 26 is raised, so that the check valve 4 is opened and water from the tank is supplied to the toilet 1. .

Therefore, the flushing device for toilet seat of the present invention is water is supplied to the toilet seat 1 after a predetermined time delay when sitting and sitting on the toilet seat (5), so that the water is discharged immediately when standing up from the toilet seat to discharge the water again in the final after treatment The conventional problem of wasting water is solved.

In addition, since the conventional flushing device for a toilet of the present invention is provided with a conventional manual flushing device, that is, a flushing lever 2, the check valve 4 may be opened and closed in the event of an unexpected failure of the flushing device of the present invention. .

According to the flushing device for toilet according to the present invention as described above, when the toilet seat (5) standing up after the toilet, the corrugated pipe (16) and the compressed toilet seat (5) is restored while the narrow air access passage (11) Due to the slow inflow of air through 12), the time is delayed until the check valve (4) is opened. Accordingly, even if only a little occurs in the toilet seat during the toilet, the water is immediately supplied to the toilet to drain the water again during the final treatment. Since it is solved, there is an effect such as saving water.
