Description
Technical field
The utility model relates to a kind of chair, particularly a kind of chair of family expenses correcting sitting postures.
Background technology
Chair is indispensable thing to sit in routine work, study and life.People are sitting in when working on chair or learning for a long time, and correct sitting posture should be that upper body is straight and upright, draw the abdomen, and the micro-receipts of lower jaw, two lower limb close up, if abnormal sitting posture is true, easily causes physical abnormality or cause people's discomfort.For the adolescent student of growing for health, the upper time keeps correct sitting posture even more important while being sitting in chair learning, if abnormal sitting posture is true, can affect body development, and teen-age health is impacted.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of chair of family expenses correcting sitting postures is provided, simple in structure, effectively corrects the incorrect sitting posture of user.
The technical solution of the utility model is: a kind of chair of family expenses correcting sitting postures, comprise sitting face, the chair back and chair leg, the one side that the corresponding people of the described chair back sits is provided with approach switch, on the back side of the chair back, control box is installed, control box is provided with control chip, buzzer, power switch and battery compartment, battery is installed in battery compartment, and approach switch, buzzer, power switch and battery compartment are electrically connected with control chip.
Described control chip is Programmable Logic Controller PLC.
The model of described Programmable Logic Controller PLC is AX80.
Described approach switch is three-wire system approach switch.
Described approach switch is embedded in the middle part of the chair back, and approach switch and the chair back are in the same plane.
The upper surface of described sitting face and the chair back are covered with ventilation cushion layer.
Adopt technique scheme: the left and right both sides of sitting face rear upper end face are arranged with upwardly extending support arm, support arm recedes, between described two support arms, be provided with along the axially extended chair back of support arm, lower end and the sitting face of the chair back leave spacing distance, the cross section of the described chair back is minor arc, the chair back curved and the certain angle that recedes, the effectively back of support human body, reduce the pressure of health to backbone, effectively slow down the fatigue that keeps for a long time sitting posture to cause.The concave surface of the arc chair back forward, the concave surface middle part of the described chair back is provided with a pressure sensor, on the convex surface of the chair back, buzzer is installed, power switch and power storehouse, pressure sensor, buzzer, power switch and power storehouse electrical connection, in the time that user adopts correct sitting posture, pressure sensor can sense the pressure of user back to the chair back, now buzzer is not worked, in the time that user departs from the chair back because of sitting posture mistake back, the force value that pressure sensor is accepted is zero, buzzer work, remind in time user's sitting posture mistake, effectively correct the incorrect sitting posture of user, in the time correcting function without use, turn off the power switch at the chair back back side.
Pressure sensor is embedded in the middle part of chair back concave surface, and pressure sensor and the chair back are positioned in same cambered surface, foreign sense when user leans against the chair back.
Be further described below in conjunction with the drawings and specific embodiments.
