the power supply module comprises a battery arranged in the chair back 1, and an electric quantity detection circuit and a driving circuit which are respectively connected with the battery, wherein the driving circuit is connected with the control module;

a charging interface 1-1 connected with a battery is arranged at the side section of the chair back 1, and an indicator lamp 1-2 and an alarm lamp 1-3 are respectively arranged at the armrest at one end of the chair back 1;

the heating and heat-preserving module comprises a resistance wire 4, a heating circuit, a heat-preserving circuit, a switch circuit and a temperature detection sensor (5); the resistance wire 4 and the temperature detection sensor (5) are arranged in the center of the lower end face of the surface layer 2-1; the temperature detection sensor 5 is connected with a control module, the control module is connected with a switch circuit, the switch circuit is respectively connected with a heating circuit and a heat preservation circuit, and the heating circuit and the heat preservation circuit are connected with the resistance wire 4;

a use method of a chair capable of intelligently adjusting temperature comprises the following steps:

a. when a user sits on the chair seat surface layer 2-1, the pressure detection sensors 2-4 arranged in the surface layer 2-1 in an annular mode transmit acquired voltage signals to the control module through conversion and amplification, the conversion circuit adopts a direct current full-arm bridge circuit, and the output and input relation of the full-bridge circuit is as follows:

wherein, U₀Representing the output voltage, U_iWhich is representative of the input voltage, represents the input voltage,

if the user completely sits on the pressure detection sensor 2-4 on the surface layer 2-1, namely the pressure center of the user is superposed with the geometric center of the seat, the amplified voltage reaches a threshold value, and the control module starts the temperature detection sensor 5; if the user does not completely sit on the pressure detection sensor 2-4, namely the pressure center of the user is not coincident with the geometric center of the seat, the alarm lamp 1-3 is on;
