Abstract

A health chair includes a chair body, a pressure detection device located within the chair body and composed of a plurality of piezoelectric sensors for generating conduction signals at a conducting stage, wherein the conducting stage is triggered at a predetermined pressure, an alarm device, and a logic processing unit electrically connected to the pressure detection device and the alarm device for analyzing the conduction signals from the pressure detection device, so as to determine whether to trigger the alarm device and, thereby, to notify the user on the chair body.

Claims

1. A health chair comprising:

a chair body;

a pressure detection device located within said chair body and composed of a plurality of piezoelectric sensors, the pressure detection device generating a weight distribution signal for user and generating conduction signals at a conducting stage, wherein said conducting stage is triggered at a predetermined pressure;

an alarm device; and

a logic processing unit electrically connected to said pressure detection device and said alarm device for identifying weight distribution signal and counting said conduction signals from said pressure detection device,

when a user is identified to sit on the health chair and a counting number of the conduction signals exceeds a predetermined value, the logic processing unit triggers said alarm device and thereby notifying the user on said chair body.

2. The health chair as claimed in claim 1, wherein said logic processing unit is a logic processor having functions of operating, power providing, and timing.

3. The health chair as claimed in claim 1, wherein said alarm device is a buzzer.

4. The health chair as claimed in claim 1, wherein said alarm device is a vibrator.
