Description

An intelligent chair for the elderly

technical field

The invention relates to the field of intelligent furniture, in particular to an intelligent chair for the elderly.

Background technique

At present, smart furniture is developing rapidly, especially smart furniture for young people is getting more and more attention from manufacturers, while smart furniture for the elderly is still in its infancy. Especially the modern old people rest at home, they will sit on the sofa or chair to read the newspaper or watch TV, because sitting for a long time will cause the blood circulation in the lower limbs of the old people is not smooth, and it is difficult for the old people to stand up. At the same time, the old people are prone to fatigue, sleepiness and dozing off In some cases, there will be problems such as catching cold or inadvertently leaning forward and falling. At the same time, due to prolonged sitting and sleeping, blood circulation is not easy, resulting in insufficient blood supply to the brain. When the elderly wake up or get up, they are prone to dizziness, tinnitus, and blurred vision.

Chinese patent CN201410266961.7 discloses a reminder device for sedentary sleepiness of the elderly. Several pressure-controlled switches are installed in the seat cushion of the chair, and several iron sheets are evenly distributed along the length direction in the safety belt. Electromagnet, the old man wears a pulse sensor on his wrist; the movable tablet is equipped with an eye-closed monitoring module and a flash light, and a vibrator and a heating resistor are installed under the voltage-controlled switch; when the voltage-controlled switch is triggered, the single-chip microcomputer starts timing. Set the time, the buzzer module sends out a reminder sound, the electromagnet is energized, the safety belt and the electromagnet are attracted to restrain the old man on the back of the chair; after 30s, if the old man still does not leave the chair, the vibrator vibrates; after another 30s, the old man Still not getting up, the heating resistor and the flashlight are powered on at the same time. When the old man falls asleep, the closed-eye monitoring module is triggered to input a signal to the single-chip microcomputer. The invention can determine whether the old man is sedentary or dozing off, and has various reminder methods, so as to achieve the purpose of protecting the old man. However, the above-mentioned sedentary drowsiness reminder requires a large number of parts to be assembled, and the above-mentioned device judges whether the old man enters sleep mainly through the designed sedentary reminder time and image recognition. Judgment happens.
