[0046] Furthermore, the third and fourth modules have the same structure and are relatively distributed; the third module includes a third assembly groove 411 opened at one end of the base 111, the third assembly groove 411 is located in the middle of the base 111 and contains the third module 412; two second magnetic snap-fit assemblies are relatively distributed, each second magnetic snap-fit assembly is composed of a second magnetic structure and a second magnetic snap-fit structure, and the second magnetic structure includes a slot opened on the side wall of the third assembly groove 411, each slot contains a third electromagnetic plate 912, and a fourth electromagnetic plate is disposed on the side wall of the third module 412, and the fourth electromagnetic plate and the third electromagnetic plate 912 are magnetically attracted; the second magnetic snap-fit structure includes a flexible mounting plate 811 fixed to the inner end of the third module 412, and a locking strip 812 is fixed on the side of the mounting plate 811 away from the third module 412; it also includes a locking seat 813 fixed to the middle side of the top of the base 111, and the locking seat 813 and the locking strip 812 are adapted to engage.
[0047] Combination Figure 3 As shown, the third assembly slot 411 is an open-end slot structure, and the third module 412 inside it can be used for support. The third module and the fourth module have the same structure and are relatively distributed. At the same time, the second magnetic snap-fit components respectively provided between the third module, the fourth module and the base 111 are also relatively distributed. Taking the third module as an example, the third module 412 and the third assembly slot 411 are connected by the second magnetic snap-fit components. Figure 5 , 6 As shown, the second magnetic snap-fit assembly is composed of a second magnetic structure and a second magnetic snap-fit structure. This ensures that the third module 412 and the base 111 can be quickly assembled and disassembled through the second magnetic structure. The second snap-fit assembly is also reinforced to prevent slippage and improve the stability of the assembly.
[0048] It is worth noting that the electromagnetic plates here can be embedded or attached.
[0049] Furthermore, each third assembly slot 411 is also provided with a second track insertion assembly on its sidewall. Each second track insertion assembly is fixed to two rails 712 on both sides of the third module 412, and has a groove 711 on the sidewall of the third assembly slot 411 that engages with the rails 712. The second track insertion assembly functions similarly to the first track insertion assembly, and the structure is combined...

[0050] Example 2
[0051] In another embodiment of this utility model, the first module 212, the second module 312, and the third module 412 are all composed of an outer layer and an inner layer. The outer layer is made of high-density memory foam to provide basic support. The inner layer has an airbag built in. The airbag is connected to the air inlet valve 101 and the air outlet valve 102 provided on the side wall of the outer layer. The air inlet valve 101 and the air outlet valve 102 are used for inflating and deflating the airbag, respectively.
[0052] The outer layer of each module here uses high-density memory foam, which is soft yet has a certain degree of support and elasticity, ensuring the comfort and support effect of each module;
[0053] The built-in airbag is connected to a manual or electric air pump via an air inlet valve 101 to adjust the air pressure of the airbag, thereby adjusting the support height and width of each module.
[0054] For example, after abdominal surgery, the second module is connected to an air pump, and the air bladder inside the second module is adjusted to inflate, so that the slope of the second module 312 is tilted at 30°. Then the third or fourth module is inflated, so that the patient's legs are raised by 15°.
[0055] Furthermore, flexible heating elements and cooling gel layers are embedded in the interlayer of the first module 212, the second module 312, and the third module 412, respectively, as well as temperature sensors respectively disposed on the outer layer of the first module 212, the second module 312, and the third module 412 and connected to the corresponding flexible heating elements and cooling gel layers, to prevent the first module 212, the second module 312, and the third module 412 from overheating or overcooling.
[0056] Flexible heating elements and cooling gel layers are embedded in the interlayer of each module. The temperature can be adjusted by a microcontroller. This is a mature existing technology. When the temperature sensor detects that the pillow temperature is too high or too low, the microcontroller adjusts the operation of the cooling gel layer or the flexible heating elements to cool or heat the pillow.
[0057] The temperature sensor here monitors the temperature of the outer layer of the pillow in real time and has a preset temperature threshold to prevent overheating or overcooling, while the temperature display is located on the outer surface of each module and can be controlled by a button or a mobile APP.

When each module is assembled with the base 111, it can be powered by the base. It is worth noting that each module is equipped with a connection socket and a connection plug between it and the base 111. When the assembly is completed, the battery inside the module is connected to the battery of the base 111 to realize the charging process of the module. The USB interface 103 on the side wall of the base 111 can also enable the battery inside the base 111 to charge the mobile phone.
[0059] Furthermore, the outer layers of the first module 212, the second module 312, and the third module 412 are all covered with pillowcases made of medical-grade antibacterial and hypoallergenic fabric. The pillowcases are removable and washable. The inner layers of the first module 212, the second module 312, and the third module 412 are each covered with an elastic waterproof and impermeable layer to prevent liquid from seeping into the airbag. Furthermore, the edges of the first module 212, the second module 312, and the third module 412 are all designed with rounded edges. And the seams of the first module 212, the second module 312, and the third module 412 are bonded using ultrasonic pressing technology, with no stitches.
[0060] Each module features rounded edges to prevent sharp corners from scratching patients. The seams are sealed using ultrasonic pressing technology, eliminating stitches, reducing bacterial growth, and ensuring aesthetics. The pillowcases fitted with the modules have evenly distributed ventilation holes to prevent the patient's mouth and nose from being blocked when lying face down.
