It is electrically connected to the controller 42 and can supply power to the graphene heating layer 4 to heat up the graphene heating layer 4 and then heat up the entire pillow. The pillow can also be used normally without an external fixed power source.

[0040] The carbon atoms in the graphene heating layer 4 generate heat energy by friction and collision (also called Brownian motion), which is radiated in the form of far infrared rays with a wavelength of 5-14 microns. The wavelength of 5-14 microns is close to and partially overlaps with the human body. The wavelength of the infrared light waves emitted is easier to penetrate the human body to promote blood circulation and achieve physical therapy functions. It is well absorbed by the human body, and the effective electrothermal conversion rate is more than 99%. In addition, the high thermal conductivity of graphene can ensure rapid and uniform heating. The heating film made of graphene has a low working voltage and a low-voltage output of 5V, which is lower than the safety voltage of the human body, which is conducive to improving the safety performance of the electric blanket and is convenient for users to use.

[0041] like Figure 2 and Figure 3 As shown, the mobile battery pack 43 is detachably connected to the controller 42 , and the mobile battery pack 43 is built into the pillowcase 3 or placed outside the pillowcase 3 .

When the two Velcros are attached, the mounting portion can be closed, and the mobile battery pack 43 can be fixed in the mounting portion to prevent the mobile battery pack 43 from moving around; when the two Velcros are separated, the mobile battery pack 43 can be taken out.

[0051] In the above solution, the closing strip may not be provided as a limiting member, and the inner side of the pocket of the mounting portion may be directly bonded to the inner cover 2 by Velcro, which may also play the same role.

[0052] The controller 42 is connected to a first connector 441 , the mobile battery pack 43 is connected to a second connector 431 , and the second connector 431 is plugged into the first connector 441 .

[0053] Specifically, the controller 42 is connected to a connecting line 44 extending to a certain extent, and one end of the connecting line 44 is connected to the first connector 441. When the second connector 431 is plugged into the first connector 441, the mobile battery pack 43 is connected to the controller 42, and the mobile battery pack 43 is powered; when the second connector 431 is disconnected from the first connector 441, the mobile battery pack 43 is not powered.

[0054] like Figure 2 As shown, a notch 31 is provided on one side edge of the pillowcase 3 , and the controller 42 passes through the notch 31 and protrudes outside the pillowcase 3 .

[0055] Specifically, the controller 42 is protruding from the pillowcase 3 to facilitate user operation; the pillow mainly works in the central part, and the controller 42 is arranged on one side edge of the pillowcase 3 to avoid the controller 42 pressing on the body and causing discomfort when the user uses it.

[0056] A zipper opening is provided on the other side of the pillowcase 3, and the mounting portion is arranged corresponding to the zipper opening.

[0061] The inner cover 2 is arranged in a multi-layer structure, the graphene heating layer 4 is arranged between the multi-layer structures, and the outermost layer and the innermost layer of the multi-layer structure are soft layers.

[0062] Specifically, the outermost layer and the innermost layer of the multi-layer structure are soft layers, which can prevent the graphene heating layer 4 from rubbing against the human body, enhance the overall softness of the pillow, and enhance the comfort of the pillow.

[0063] The pillow gear position can be adjusted, and the controller 42 is provided with a color-changing indicator light corresponding to different gear settings.

[0064] Specifically, when the controller 42 is connected to the mobile battery pack 43 or the controller 42 is connected to a fixed power supply, the controller 42 will light up once in the order of low-medium-high white-orange-red, and then enter the red light flashing state. When the built-in mobile battery pack 43 is connected, it indicates that the mobile battery pack 43 is being charged; when the mobile battery pack 43 is not connected, it indicates the standby state, and the user can long press the power button to use it powered by a fixed power supply.

[0067] 3. The product is in use and connected to a fixed power source. The product remains in use, but the power supply from the mobile battery pack 43 is adjusted to the fixed power source.

[0068] If the shutdown operation is performed again, the red light of the controller 42 flashes, and the mobile battery pack 43 is charged;

[0069] If the fixed power source is disconnected again, the mobile battery pack 43 continues to supply power to the product.

[0070] The controller 42 and the mobile battery pack 43 are not connected: the controller 42 can only be used by first connecting it to a fixed power source and then pressing and holding the button of the controller 42 for 2 seconds to turn it on.

[0071] The graphene heating layer 4 includes a graphene heating film 41 , on which an NTC module 45 is provided for detecting and controlling temperature. Both the graphene heating film 41 and the NTC module 45 are electrically connected to the controller 42 .

[0072] Specifically, after booting up, the device will enter the low temperature setting of 30℃-35℃ by default, and the white light will be on all the time;

[0073] Click the controller 42 to switch to the medium temperature range of 35℃-40℃, the orange light is always on; the high temperature range of 40℃-45℃, the red light is always on; three-level temperature one-way cycle: low-medium-high-low.
