Description

The chair of family expenses correcting sitting postures

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.

In accompanying drawing, 1 is sitting face, and 2 is chair leg, and 3 is control box, and 4 is the chair back, and 5 is approach switch, and 6 is buzzer, and 7 is power switch, and 8 is control chip.

The specific embodiment

Referring to Fig. 1 to Fig. 4, a kind of chair of family expenses correcting sitting postures, comprises sitting face 1, the chair back 4 and chair leg 2, and the upper surface of sitting face 1 and the chair back 4 are covered with ventilation cushion layer.The one side that the corresponding people of the described chair back 4 sits is provided with approach switch 5, and approach switch 5 is embedded in the middle part of the chair back 4, and approach switch 5 is in the same plane with the chair back 4, the present embodiment, and approach switch 5 is three-wire system approach switch.Control box 3 is installed on the back side of the chair back 4, control box 3 is provided with control chip 9, buzzer 6, power switch 7 and battery compartment 8, battery is installed in battery compartment, approach switch 5, buzzer 6, power switch 7 and battery compartment 8 are electrically connected with control chip 9, the present embodiment, and control chip 9 is Programmable Logic Controller PLC, model is AX80, Programmable Logic Controller PLC receives the input signal of approach switch, and output prompting control signal, to the control circuit of buzzer, is controlled buzzer and sent prompt tone.Referring to Fig. 5, the control circuit of buzzer comprises resistance R 1, triode Q1, one end of described resistance R 1 is connected with the output of Programmable Logic Controller PLC, the other end of described resistance R 1 is connected with the base stage of triode Q1, the grounded emitter of triode Q1, the colelctor electrode of triode Q1 connects the power-terminals of buzzer, and the positive terminals of power supply of buzzer are connected with VCC power supply.

When use, in battery compartment, pack battery into, turn on the power switch, user is sitting in sitting face, leans against the chair back, and upper body is straight and upright, draw the abdomen, the micro-receipts of lower jaw, two lower limb close up, with correct sitting posture study or work, now approach switch no signal output, buzzer is sounding not, if user is not sitting on chair according to correct sitting posture, approach switch sends signal, and buzzer is sounded and reminded in time user's sitting posture mistake, effectively corrects the incorrect sitting posture of user.If while correcting function without use, turn off power switch.
