When the sliding variable resistor moves along the floating plate toward the connection back plate, the resistance connected to the sub-control element increases, which is used to adjust the heating power of the heating wire.

[0022] When the multifunctional mattress is used to control the internal temperature of the multifunctional mattress, the following steps are included:

[0023] S1: When a sleeper lies on the outer skin of the mattress, the unit airbags are squeezed by the weight of the body, and with the increase of pressure, the volume of the internal cavity of the unit airbag becomes smaller, and the internal air pressure increases, so that the gas squeezes the floating plate to slide inside the connecting sleeve toward the connecting back plate, so that the distance between the distance measuring sensor and the distance measuring receiver is shortened, that is, the main controller controls the opening of the heating wire in the corresponding unit airbag that produces the pressure change, so as to heat the unit airbag in the user coverage area;

[0024] S2: After the set time, the internal gas of multiple unit airbags in the user coverage area expands due to heat, causing the internal pressure of the unit airbags to increase, forcing the unit airbags to deform, thereby causing the floating plate to be further compressed. When the floating plate moves a distance exceeding the set value, the first electrically controlled valve and the third electrically controlled valve are opened synchronously, and the air inside the heating unit airbag is transferred to the remaining unit airbags by starting the first silent air pump, and the air is transferred in a manner of gradually decreasing the ventilation volume as the distance increases. At the same time, the third silent air pump is started to re-transmit the air originally stored in the unit airbag to the unit airbag that has completed the air delivery, so that the gas pressure between the multiple airbags is kept in the same range, so as to prevent the locally heated unit airbag from expanding much more than the adjacent unit airbag. At the same time, the gas inside the airbag that is not subjected to the user's body pressure is preheated, and then the first electrically controlled valve and the third electrically controlled valve are closed;

[0025] S3: When the temperature and air pressure in multiple unit airbags within the user coverage area tend to be stable, the first electrically-controlled valve and the third electrically-controlled valve connected between all unit airbags at the edge of the coverage area and the unit airbags in the uncovered area are kept closed, and the movement distance data of the floating plates in all unit airbags in the user coverage area are obtained. The third electrically-controlled valve and the second electrically-controlled valve connected to the unit airbags whose movement distance data exceeds the threshold are opened, and the first electrically-controlled valve connected to the unit airbags whose movement distance data does not exceed the threshold is opened. The gas in the unit airbags that do not exceed the threshold is transported to the unit airbags that exceed the threshold through the corresponding first silent air pump, second silent air pump and third silent air pump, so as to adjust the supporting force of the unit airbags in the areas under greater pressure within the user coverage area.

[0026] Beneficial effects of the present invention:

[0027] 1. On the basis of conventional electric heating mattresses, the entire electric heating structure is modified. The electric heating wire is arranged in a hollow air bag structure. The compressed air inside the air bag structure prevents the user from directly contacting the electric heating wire, so as to prevent the pressure generated by the user's body from being directly transmitted to the resistance wire layer, so as to solve the problem that the resistance wire layer is bent due to uneven force;

[0028] 2. By setting a pressure-sensitive temperature control component, when the user lies on the mattress, the body will exert a force on the mattress, causing the unit airbag to deform. After detecting the pressure change, the pressure-sensitive temperature control component will control the electric heating wire to open and close, so as to heat only the unit airbag supporting the body part, thereby reducing the energy consumption of the entire multifunctional mattress to a certain extent. At the same time, the pressure-sensitive temperature control component can control and adjust the temperature inside the unit airbag, so as to adjust the heating efficiency of the electric heating wire by adjusting the temperature inside the unit airbag, thereby further reducing the energy consumption of the entire mattress, and thus significantly reducing the use cost of the entire multifunctional mattress;

[0029] 3. The gas inside several unit airbags is exchanged with each other through the setting of the balance component, and the gas inside the unit airbags that are not squeezed by body parts can be preheated in accordance with the principle of gradually decreasing the ventilation volume as the distance increases, so as to adapt to the rapid heating after the sleeper turns over. At the same time, the gas inside the unit airbags squeezed by body parts will also be cooled down again under the heat exchange effect of the low-temperature gas, so as to reduce the impact of the thermal expansion of the gas on the unit airbags squeezed by body parts.

[0060] When the multifunctional mattress is used to control the internal temperature of the multifunctional mattress, the following steps are included:

The ventilation volume is gradually decreased, and the air originally stored in the unit airbag 201 is re-transmitted to the unit airbag 201 that has completed the air supply by starting the third silent air pump 3303, so that the gas pressure between the multiple airbags is kept in the same range, so as to prevent the expansion degree of the locally heated unit airbag 201 from being much greater than the expansion degree of the adjacent unit airbag 201, and at the same time, the gas inside the airbag that is not subjected to the user's body pressure is preheated, and then the first electric-controlled valve 3102 and the third electric-controlled valve 3302 are closed;
