Description

BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The invention relates to the field of sanitary ware, in particular to peripheral ergonomic equipment for a seat toilet.

Description of Related Arts

The toilet is divided into a squat toilet and a seat toilet. Because the seat toilet is more comfortable and civilized than the squat toilet, it is widely popular in modern society.

When we are squatting, the angle between the upper body and the thigh is 35 degrees, which is the best angle for human body excretion, because the bowel movement is straight down. However, when sitting on the seat toilet, the angle between the upper body and the thigh is 80 to 90 degrees, which would hinder the smoothness of the intestine, leading to constipation and hemorrhoids.

The toilet stool improves the excretion angle when people use the seat toilet by raising the lower limbs, but it is still difficult to achieve the squatting effect. Our analysis believes that the reason lies in:

1. the height of the toilet and the toilet stool is constant, and the height and the leg length of the users are different, so it is difficult to achieve the optimal human excretion angle;

2. compared with the squatting that the body leans forward, the waist and the back are tense for body balance, while sitting on the seat toilet, the waist and back are slack, and the back and abdomen muscles could not participate more to promote bowel movements;

3. when squatting, the thighs are in close contact with the abdomen, furthermore, the abdomen is continuously squeezed to promote defecation, however, when sitting, there is no contact between the thighs and the abdomen, and there is no squeezing effect on the abdomen.

Therefore, there is a need for a peripheral device suitable for the seat toilet, which obtains good support of the lower back when the user defecates, continuously adjusts the height of the lower limbs, and continuously compresses the abdomen, thereby achieving a smooth and convenient bowel movement.

SUMMARY OF THE PRESENT INVENTION

An ergonomic toilet equipment comprises a backrest device, a pedal device, and an abdominal pressure assisting device, said backrest device comprising a bottom substrate, an airbag array system, and a surface cover cloth, said bottom substrate being disposed on the inner side surface of the toilet cover, said middle layer airbag array system comprising a few air bags, an inflation path, an suction path, a few electromagnetic valves, an inflation pump, a suction pump, a few pressure sensors, a central data processor, a wireless communication module, an intelligent control terminal, and a power.

(c) if the pressure value difference between the left and right sides of the air bags 121 and the user body is more than 30 mmHg, it indicates that the user might be sitting incorrectly, then the user would be reminded to adjust the sitting posture;

(d) if the pressure value between the air bags 121 and the user body continues to be less than 80 mmHg, it indicates that the inflation pump 125 might be malfunction, while, if the inflation pump 125 works normally, then the inflation path 123 and/or the air bags 121 might be leakage;

(e) if the pressure value between one of the air bags 121 and the user body continues to be less than 80 mmHg, it indicates that the air bag 121 might be broken, while, if the air bag is in good condition, then it indicates that the path and/or the branch might be leakage;

(f) when the user stops usage, the suction pump 126 works, if the pressure between the air bags 121 and the user body remains more than 120 mmHg, or the pressure values of all the air bags 121 are not lowered, it indicates that the suction pump 126 might faulty;

(g) if the inflation and/or suction function does not work, it indicates that the inflation path 123 or suction path 126 might be damaged; and
