Background

In terms of physiological structure, squatting and defecation are smoother, but nowadays, most families are provided with the toilet bowl, so that the best sitting posture of the toilet bowl is sought. According to the survey, the defecation is smoother when the anorectal angle formed by the rectal muscle and the rectum is larger and the rectum is straighter. When sitting, the anus and intestine angle is about 80-90 degrees, and when squatting, the anus and intestine angle can reach 100-110 degrees. In addition, the pressure of the abdomen is large when squatting, which can promote defecation. Especially for people with cardiovascular and cerebrovascular diseases, the squatting defecation can reduce the probability of accidents.

In the embodiment, the flushing device adopts a normally closed pilot electromagnetic valve, when the first infrared sensor 15 detects that a human body leaves, the toilet cover is automatically closed, the steering engine feeds back information to the AT89C2051 single chip microcomputer AT the moment, the AT89C2051 single chip microcomputer receives the information to judge and controls the electromagnetic valve to be electrified, when the electric power is on, the electromagnetic force attracts the valve core of the pilot hole, the pilot hole is opened, the pressure of the upper cavity of the piston of the main valve is reduced, the upper and lower high pressures are formed in the upper cavity and the lower cavity of the main piston, and thus the pressure of the lower cavity pushes the; when the power is cut off, the spring force resets to close the pilot hole, the upper cavity of the main piston is pressurized, high pressure and low pressure are formed in the upper cavity and the lower cavity of the main piston, the medium pressure and the spring force push the main piston, and the valve is closed.

The human body infrared signal acquisition circuit in the embodiment is formed by an SM9576, the SM9576 is an infrared sensing controller, the interior of the SM9576 comprises an infrared emission drive circuit, an infrared receiving circuit and an infrared detecting circuit, when an infrared signal is emitted and reflected by an object, the infrared signal is received, amplified and detected by a receiver, and then an output circuit controls an actuating mechanism. According to practical requirements, a continuous level is output in the whole process of human induction occurrence and human stay, when P0 and P1 of SM9576 are both disconnected, the output of 0UT0 meets the requirement, only a high level is output when induction exists, and a low level is output when no induction exists. When no person passes by, the circuit is in a state of continuously emitting infrared rays outwards, when the diode between the pin 20 and the pin 15 emits the infrared rays outwards, the emitted infrared rays are reflected back after detecting a human body and are sensed by the diode between the pin 18 and the pin 17, so that the original low level is changed into the high level on the pin 12, the high level is continuously kept in the process that the person does not leave all the time, and the low level is changed back when the person leaves. Because infrared induction all contains certain distance restriction, this induction circuit relies on 104 electric capacity to realize distance control, and the size of electric capacity directly determines can the size of induction distance, and when the electric capacity changes between 0.01uf-0.1uf, the induction distance is from 5cm-25 cm.

The present embodiment adopts a switching power supply circuit, as shown in fig. 5, and its main function is to provide +5V, +12V, +24V dc voltage and PWM signal to the main control board. The AC220V commercial power is filtered by the power input filter circuit to remove high frequency noise. Then rectifying and filtering are carried out to obtain the direct current voltage of 300V. Then, a +5V, +12V, +24V alternating current converter circuit composed of the electric switch converter, the switching tube and the IC chip generates the required pulse alternating current voltage at the secondary side of the switch; finally, the +5V, +12V and +24V direct current voltage are generated through a rectifying and filtering circuit. The +5V is mainly used for supplying power for a system control circuit and a general circuit, the +12V is used for supplying power for a pressure reducing valve, and the +24V is used for supplying power for a 90-degree steering engine.

When this concrete implementation used, when the second infrared inductor detected that the people is close to the closestool, the closestool inside and outside lid was all opened, if there is the inner cup lock that needs, then can select at the main control board. If the inner cover is buckled, the pedal is put down, as shown in figure 2:

when a person sits on the toilet seat, the first infrared sensor detects the person and transmits the detected result to the main control board, and then the pedal is controlled to slowly lift until the angle of the person accords with the optimal sitting posture, as shown in fig. 3.

When a human body leaves the seat ring, the first infrared sensor detects signals and feeds detection results back to the main control board, and the foot pad board returns to a closed state, so that space utilization is saved, and the comfort level of human defecation can be guaranteed. Meanwhile, the toilet lid is closed to perform a series of actions such as flushing, deodorization and the like.
