Abstract
The utility model relates to a control device of a pressure sensor of a seat toilet, which can be used for automatically distinguishing urine and stool so as to flush. The control device comprises a pressure sensor. The input end of a single-chip is connected with a flag bit of the pressure sensor. According to the time length of human pressure, the control device can automatically distinguish the urine and stool; the single-chip program and the flag bit are used for setting the critical time of the urine and stool; the control device controls an electromagnetic valve, which is connected with the output end of the single-chip, to automatically flush according to the preset flushing quantity for the urine and stool. The combination of grounding and suspending the flag bit can determine the critical time of different urine and stool. The suspension of the flag bit equals to no arrangement of the flag bit. The control device overcomes the defect that the existing seat toilet can not distinguish the urine and stool according to the self pressure so as to automatically flush. And the control device adopts the pressure sensor to automatically distinguish and flush according to the difference of the urine and stool, and can be widely used in the water-saving seat toilet.
Description
Technical field
The utility model relates to the control device of the automatic separating shit and urine bath of a kind of toilet, the control device of the automatic separating shit and urine bath of particularly a kind of toilet working pressure sensor.
Background technology
The utility model is before the applying date, and prior art stepping formula toilet adopts big or small discharging quantity of water button manually to distinguish the excrements bath, makes troubles to the user, especially is not suitable for the public place and uses.Single grade of formula toilet can't cause the waste of water resource according to change the bath of excrements crash time differentiation excrements with the lavatory custom.
Summary of the invention
The purpose of this utility model provides a kind of control device of toilet working pressure sensor automatic distinguishing excrements bath.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises pressure sensor.The single-chip microcomputer input is connected with flag bit with pressure sensor, length according to human pressure's time, automatically discern excrements, by the crash time of SCM program and flag bit setting excrements, the electromagnetic valve that control is connected with the single-chip microcomputer output is by the excrements discharging quantity of water auto-flushing of setting.Excrements crash time be time constant, determine crash time of different excrements by flag bit ground connection and unsettled combination, when flag bit when being unsettled, be equivalent to and do not establish flag bit.Flag bit is a toggle switch.
The beneficial effects of the utility model are to have overcome existing toilet not have the defective of washing by water by self pressure automatic distinguishing excrements, provide a kind of working pressure sensor automatic separating shit and urine control device, can be widely used in the control of water-saving closestool.
