Under the action of the air pressure, the air outside the main unit generates a wind speed to make the air flow. The flowing air enters the air duct of the main unit through the input port of the air duct. In the air duct, there is a module in a refrigeration state or a heating state. After the air flowing through the refrigeration module or the heating module is temperature-treated, it is then output from the air outlet of the main unit and enters the inside of the mattress.

And it will gather in the air duct. Cold energy will be generated on the reverse side of the Peltier wire 13, which is also transferred to the large aluminum evaporation sheet housing 11 outside the channel through silicone grease for cold energy evaporation. There are 2 square fans working side by side near the large aluminum evaporation sheet housing 11. When the square fans work, the air flow speed on the surface of the large aluminum evaporation sheet housing 11 is accelerated, and the evaporation efficiency of the large aluminum evaporation sheet housing 11 is improved. While improving the evaporation efficiency of the large evaporation sheet 11 outside the air duct, the evaporation efficiency of the small aluminum evaporation housing 12 in the air duct will also be improved.

[0089] As Figure 6 Shown: Introduction to the working principle of the single-channel module: A partition 20, a set of refrigeration and heating modules, a turbo fan, and an air duct are assembled together by screws to form a single-channel module. The single-channel module seals the area around the channel.

They are assembled together with screws to form a refrigeration and heating module. Note: Thermal conductive silicone grease should be applied to the front and back of the four Peltier elements.

[0092] As Figure 8 shown: The working principle of the dual-channel module: The dual-channel air duct is divided into a left air duct and a right air duct by a separator, and they are assembled together with screws to form a dual-channel module. The dual-channel module is hermetically treated around the channels.

[0097] As Figure 9 shown, the mattress 1 has an electric control system; the electric control system includes a main control board; the main control board circuit is electrically connected to an AD / DC switching power supply, a fan assembly, and a Peltier assembly respectively;

[0098] The fan assembly includes square fan 10 and vortex fan A17;

[0099] The Peltier assembly includes Peltier A7;

[0100] The controller includes a wired hand controller or a wireless remote controller;

[0101] The main control board includes a single-chip microcomputer MCU; the single-chip microcomputer MCU is electrically connected to the AD / DC switching power supply through a DC-DC circuit;

[0102] The single-chip microcomputer MCU accesses the wireless remote controller through the wireless receiving module and / or the RF module; the single-chip microcomputer MCU is also electrically connected to the buzzer, the built-in MOS tube driver chip circuit and the built-in H-bridge chip circuit;

[0103] The pulse width modulation driver is electrically connected to the fan assembly; the built-in H-bridge chip circuit is electrically connected to the Peltier assembly; the driver uses the built-in MOS tube driver chip circuit;

[0104] Working principle: After the system is powered on by AC, the external switch power supply supplies 29V to the main control board. The DC-DC circuit on the main control board steps down 29V to 3.3V to supply power to the single-chip microcomputer MCU and the RF module and other circuits. The main power 29V supplies power to the fan drive and the H-bridge circuit. When the user needs to supply warm air to the mattress, the user sends an instruction to the main control board by operating the buttons on the wired hand controller. After the hand controller interface circuit on the main control board receives the button instruction of the wired hand controller, it is converted into a level or instruction data that can be recognized by the single-chip microcomputer and transmitted to the single-chip microcomputer for processing. When the single-chip microcomputer receives the button instruction of the hand controller, it performs relevant operations, such as turning on the Peltier heating. When the temperature of the Peltier heating rises to the user-set temperature, the fan is turned on to convey the warm air heated by the Peltier to the mattress through the ventilation pipe. At the same time, another group of fans is also turned on to blow air on the other side of the Peltier to balance the temperatures on both sides of the Peltier. Similarly, the user can also operate other functions through the wired hand controller, such as turning off the Peltier heating, adjusting the increase or decrease of the Peltier temperature rise, and adjusting the Peltier refrigeration.

[0105] In addition, the user can also send an instruction to the wireless receiving module on the main control board by operating the buttons on the wireless hand controller. After the wireless receiving module receives the button instruction of the wireless hand controller, it is converted into a level or instruction data that can be recognized by the single-chip microcomputer and transmitted to the single-chip microcomputer for processing. When the single-chip microcomputer receives the button instruction of the wireless hand controller, it performs relevant operations. Such as turning on the Peltier heating, turning off the Peltier heating, adjusting the increase or decrease of the Peltier temperature rise, and adjusting the Peltier refrigeration.

[0106] Such as Figure 11 , the single-chip microcomputer of the control box system is used to process the instructions of the wired or wireless remote controller, control the Peltier refrigeration or heating, and at the same time monitor the working current and the temperature rise of the Peltier. Collect the current and temperature rise data of the Peltier; then control the Peltier refrigeration or heating temperature through the PID algorithm of the software. The single-chip microcomputer also controls the fan to convey cold and warm air to the mattress and controls the fan to dissipate heat from the Peltier. When the electric control system encounters an abnormal situation suddenly, the single-chip microcomputer controls the buzzer to alarm.

[0107] Such as Figure 12, the user operates the buttons on the remote control. When the wireless module on the remote control receives the button command, it converts the button signal into a radio frequency signal and sends it to the wireless receiving module of the control box. After the wireless module circuit of the control box receives the wireless radio frequency signal sent by the remote control, it converts the wireless radio frequency signal into a level or instruction data that can be recognized by the single-chip microcomputer. Then, after the single-chip microcomputer receives the button command of the wireless hand controller, it performs related operations. Such as turning on the Peltier heating, turning off the Peltier heating, adjusting the increase or decrease of the Peltier temperature rise, adjusting the Peltier cooling, etc.

[0108] The wired hand controller interface circuit converts the wired hand controller button signal into a level or instruction data that can be recognized by the single-chip microcomputer and transmits it to the single-chip microcomputer for processing. Then, the single-chip microcomputer controls the operation of the fan and the Peltier. In Figure 13 it, the power supply circuit is used to supply power to the single-chip microcomputer, the hand controller circuit, and the MOS tube drive circuit.

[0109] Such as Figure 14 , the fan is controlled by the switching action of the built-in MOS tube chip drive circuit to realize the start and stop of the fan.

[0110] In Figure 15 it, the built-in H-bridge chip circuit is used to change the current direction of the Peltier to realize Peltier cooling or heating. The H-bridge circuit uses chip U5.

[0111] In Figure 16 it, the current and temperature rise acquisition circuit is used to collect the current and temperature rise data during the Peltier cooling and heating processes and feedback them to the single-chip microcomputer for precise PID control of the temperature of the Peltier cooling or heating.

[0112] In Figure 17 it, the hand controller circuit is connected to the control box to operate the fan and the Peltier.

[0113] The current and temperature rise acquisition circuit is set between the H-bridge circuit and the MCU;

[0114] The current and temperature rise acquisition circuit includes chip U5;

[0115] In Figure 15 chip U5, the current channels of the Peltier component are connected to pins 1 and 6; pin 3 is grounded through resistor R28, and the current signal collected by resistor R28 is connected to the other end of resistor R4 connected to pin 3 of U8. The over-current protection (OCP) signal of the Peltier component is amplified by U8 chip and sent to pin 21 of the MCU through pin 1; the temperature rise acquisition channel is connected to the NTC temperature acquisition circuit by pin 5 of U8, and the signal is amplified by chip U8 and output from pin 7 of U8 and connected to pin 22 of the MCU.
