Description
Technical field:
The utility model relates to the toilet technical field of automatic control, particularly is used for the auto-flushing opertaing device technical field of urinal, squat type closet or toilet.
Background technology:
The induction type urinal, squat type closet or the toilet auto-flushing opertaing device that are applied in the toilet at present all adopt reflective infrared sensor, or adopt pyroelectric infrared sensor and reflective infrared sensor to be used two kinds of induction modes in order to save power consumption, and the water outlet control device is solenoid valve or penstock motor.The former working method is: during certain distance before standing in urinal, promptly trigger infrared sensor, infrared sensor sends level signal and gives the back end control system.After urine finished to leave, infrared sensor stopped to send level signal, returns to the standby acquisition mode, and control system is sent level or pulse signal adhesive solenoid valve or driving unlatching penstock motor and kept certain hour and carry out flush operation.And the working method that rpyroelectric infrared signal and reflective infrared signal are used is responsible near the appearance of the moving human body of monitor controller for the rpyroelectric infrared signal, start the reflective infrared signal then and the people is counted urinate and defecate time of behavior, the behavior of urinating and defecating finishes the bath of back control rear end equipment.But, because there is significant difference in reflective infrared sensor to unlike material, different colours reflected by objects effect, can realize the identification of longer distance for smooth finish surface and light object, therefore then can only carry out the identification of closer distance for rough surface and dark object, can't adapt to complicated environment for use for same set of bath equipment at all and realize effective identification the people.So the phenomenon of not washing by water after an action of the bowels that adopts automatic flushing device that infrared sensor reflects identification to show in actual applications is very general.In addition, because the reflective infrared sensor automatic flushing device all is that continuous reflected signal is carried out time counting at present, in case human body owing to rocking the reflected signal pop-off that causes away from effective reflected range, also can cause the automatic flushing device erroneous judgement to cause washing by water for no reason when using just lavatory.Particularly adopt solenoid valve to exist the water yield little and be subject to the influence of supply channel flow and variation in water pressure, bath weak effect as the toilet of water outlet control device; Adopt electromagnet armature pulling water tank to clap the toilet of lid equally owing to the short disadvantage that has the weak effect of washing by water of armature movement stroke.Therefore, particularly reflective infrared signal type squat type closet and toilet auto-flushing opertaing device lack practicality to such infrared induction equipment in real life.
The utility model content:
The purpose of this utility model is to address the above problem, provide a kind of with ultrasonic sensor as main induction mode, adopt the method for ultrasonic ranging that setpoint distance is exported to central microprocessor with interior human body trigger pip, by central microprocessor signal is carried out the false triggering pattern; the classification of urine signals pattern and stool signal mode and adopt the mode of two anti-false triggerings to handle; use the just behavior equipment output to the back-end control signal in lavatory according to the people is actual then, clap lid or control and squat just that solenoid valve carries out the little water yield and big yield dual mode auto-flushing thereby drive motor the mode with the simulation staff of rotating spurs toilet to signal.This kind use ultrasonic sensor is found range to the human body reflected signal and is adopted the equipment of two anti-false triggering disposal routes to overcome the reflective infrared signal to trigger pip and there is the disadvantage of significant difference in unlike material, different colours reflected by objects effect, can accurately detects the position of various materials and color object; Simultaneously to human body before urinal through and when use squatting just with toilet accidental behavior such as body-sway motion reasonably handle, fundamentally solved the problem that the existing infrared sensor auto-flushing product in toilet exists, perfect auto-flushing reliability of products and the hommization that has improved equipment can be promoted the use of automatic flushing device widely in actual life.
For achieving the above object the technical scheme that the utility model adopted: a kind of ultrasonic sensing type intelligent flushing controller comprise ultrasound wave sensing head, ultrasonic emitting receiving circuit, effective detection range set button, central microprocessor, governor circuit, power supply circuit, bat lid, water tank, water tank drag-line, tank lid, flushing pipe, photoelectric detector support, photoelectric detector, motor, electric machine support, transmission sleeve pipe, backguy, crocodile clip, be connected as a single entity about two runners, controller box body, slotted hole, solenoid valve and flushing pipes; Described controller box body be fixedly mounted on the wall of water tank top or concealed installation in wall, ultrasound wave sensing head and effective detection range are set button and are positioned on the front panel of controller box body, the photoelectric detector support, photoelectric detector, motor, electric machine support and two runners are installed in the side in the controller box body, motor is fixed on the electric machine support, the upper end of photoelectric detector support is fixed with photoelectric detector, runner is fixed on the motor shaft, have a slotted hole at the right side edge position of right side runner, this slotted hole passes the detection mouth of photoelectric detector, the transmission sleeve pipe is positioned at the below of left side runner, the below of this transmission sleeve pipe slave controller box body passes, and enter in the water tank along passing between water tank and the tank lid or in the hole of water tank rear wall, described backguy upper end is fixed on the runner, the backguy center section passes the transmission sleeve pipe, the lower end of backguy links to each other by being connected the water tank drag-line of clapping lid in crocodile clip and the water tank, power supply circuit, ultrasonic emitting receiving circuit and governor circuit are installed in the controller box body, the output terminal of power supply circuit is connected with governor circuit and motor respectively, central microprocessor is arranged on the circuit board of governor circuit, the ultrasound wave sensing head is connected with the input end of ultrasonic emitting receiving circuit, its output terminal is connected with the input end of central microprocessor, two signal ports of this central microprocessor are connected with photoelectric detector, and the output control terminal of central microprocessor is connected with motor.

2With stool signal mode t
3The classification of comparing, read then corresponding bath time parameter to the back-end equipment send the bath instruction, this moment timer A time read t be 58 seconds continuous trigger signal time with the summation of the 2 seconds time of actual interruption 60 seconds greater than false triggering time t
19 seconds, but less than the stool signal mode t
3120 seconds, belong to urine signals pattern t
2, stop after 200 milliseconds of motor 4 forward rotation, clap and cover 10 and begun to wash by water motor 4 stall T by backguy 8 pull-ups
2Be to begin counter-rotating in 2 seconds then, when the slotted hole 17 (referring to Fig. 4) of motor runner 11b when turning to photoelectric detector 2, photoelectric detector 2 output signals are to the input end of central microprocessor 14, and central microprocessor 14 sends signal control motor 4 and stops counter-rotating end bath; When the time read t of timer A is 300 seconds, greater than stool signal mode t
3120 seconds, the disposal route of 14 pairs of trigger pips of central microprocessor was identical with above urine pattern, and motor 4 is carried out above identical rotating operation, just the time T that stops after motor 4 forward rotation
3It is 6 seconds.In addition, sometimes for the needs of toilet seat closet, can also press manual flush lever 7 and wash by water.
