I＝I₁+I₂+I₃+…+I_i

Wherein I_iThe current value of the ith induction piece 511;

s5: when I is>I_minAnd then, the heating layer 3 of the left zone or the right zone is started to start heating.

The working principle and the beneficial effects of the technical scheme are as follows: in order to better control the left area, the middle area and the right area in a differentiated manner, the induction sheet 511 is correspondingly divided into a left pressing area, a pressure area and a right pressing area, the head and the neck of the user are completely attached to the heating layer 3 and then heated, so that invalid energy consumption is avoided, a minimum starting current needs to be set for the induction sheet 511, and the heating operation is performed after the current reaches the starting current.

In one embodiment, the desired current value I is calculated_maxThe method can firstly pass the following formula

Q_max＝τkΔT/h

Calculated, where k is the thermal conductivity of the electrical resistance in the heat generating layer 3; τ is a seebeck coefficient of resistance in the heat generating layer 3; h is the length of the resistor in the heating layer 3; Δ T is the maximum temperature T of the resistor in the heat generating layer 3_maxAnd normal temperature T₀A difference of (d);

then the calculated Q_maxSubstitution formula

I_max＝[Q_max-(RI_max ²/2)-k(T_max-T₀)]/(τT₀)

Wherein R is the resistance value of the heat generating layer 3.

The working principle and the beneficial effects of the technical scheme are as follows: through the design of the structure, the heat value required to be released when the temperature is raised to the required temperature can be calculated through a formula, then the calculation result is substituted into the formula to calculate the current value when the heating layer 3 reaches the rated power, and then the required current value I is calculated_maxDefining a minimum starting current value I by user_minAnd will be (I)_max，I_min) As the value ranges of the currents in the left pressure region, the pressure region and the right pressure region, the total resistance values in the left pressure region, the pressure region and the right pressure region are respectively calculated by a resistance calculation formula R which is U/I, and the resistance value of the trigger device 51 is determined according to the total resistance value and the number of the trigger devices 51 which need to be set, so that the situation that the temperature of the heating layer 3 is too high or the heating layer is not started is ensured.
