Toilet automatic flushing device

Abstract

An automatic flushing device of a toilet bowl is provided to block a leakage of washing water discharged to ceramic ware by buoyant materials which is a control unit blocking the power transmission from a driving unit. The automatic flushing device of a toilet bowl comprises an operation unit, a driving unit, a power transmission unit, and a clutch unit. The clutch unit comprises a clutch gear and a buoyancy material. The clutch gear is engaged with a plurality of gears in the power transmission unit while a position is moved. The buoyancy material is lifted due to buoyancy according to a water level in a water tank and moves the clutch gear. A height is changed in order to control the discharge amount of washing water when the buoyancy material descends.

Description

technical field [0001] The present invention relates to an automatic flushing device for a toilet, and more particularly, to an automatic flushing device for a toilet that automatically recovers when a power failure occurs, adjusts the amount of flushing water according to the amount of urine and feces, and controls flushing when misoperation occurs Operate to efficiently conserve water. Background technique [0002] Generally speaking, when a user uses the toilet, the user can press the manual handle to flush the toilet. Then, the siphon cover is turned upward from the lower end position of the overflow pipe to open the flush water outlet, and the flush water (cleaning water) stored in the tank is discharged into the toilet bowl through the opened flush water outlet to flush away the sediment in the toilet Feces or urine in the basin. [0003] However, recently, in order to make up for the deficiency of the manual flushing device, the automatic flushing device and the man...

AI Technical Summary

Problems solved by technology

[0004] However, in the case of the related automatic flushing device, if misoperation or power failure occurs during the flushing process, the cover cannot close the flushing water outlet of the water tank, and the water is continuously discharged from the water tank, resulting in waste of water

That is, if a misoperation or power failure occurs to the automatic flushing device while the automatic flushing device is still operating, the automatic flushing device that has been operated does not return to its original state, and the leakage of the supplied flushing water cannot be blocked, and therefore, the leakage of the water still going on

[0005] In addition, the prior art automatic flushing device always discharges all the flushing water stored in the tank to flush the toilet bowl regardless of whether feces or urine has settled in the toilet

Therefore, it is not effective enough since in the case of flushing urine, the same amount of flushing water is expelled as flushing faeces

[0006] In addition, in the automatic flushing device of the prior art, when the user operates the flushing button continuously within a certain period of time, the flushing operation will be carried out continuously.

That is, if the flushing button is operated continuously due to children's playfulness (playing around) or user's incorrect operation, the amount of flushing water discharged is far greater than required
