Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0031] like Figure 1 , Figure 4 and Figure 6 As shown, this utility model provides a graphene-heated pillowcase, including a pillowcase 1. The fabric of the pillowcase 1 is divided into an outer layer 16 and an inner layer 17, with a graphene heating layer 18 disposed between the outer layer 16 and the inner layer 17. This structure facilitates the graphene heating layer 18 being wrapped inside the fabric of the pillowcase 1, ensuring the stability of the graphene heating layer 18 and making it easy for the graphene heating layer 18 to generate heat. A temperature sensor is connected to the graphene heating layer 18 to sense its temperature. A temperature controller 2 is connected to the graphene heating layer 18 to control the temperature rise of the graphene heating layer 18. The temperature controller 2 internally includes an MCU control module, including an MCU chip, which serves as the main controller for the temperature controller 2. The MCU control module is connected to a data processing module, a constant temperature control module, and an over-temperature warning module. The data processing module is used to process and judge the received temperature data, the constant temperature control module is used to control the graphene heating layer 18 to maintain a constant temperature based on the temperature data fed back by the data processing module, and the over-temperature warning module is used to issue a warning when the graphene temperature is too high.

[0032] like Figure 2As shown, the outer fabric layer 16 of the pillowcase 1 is made of skin-friendly and soft fabric, such as cotton, silk, coral fleece, milk fleece, etc., making the pillowcase 1 more comfortable to use. The inner fabric layer 17 of the pillow is made of polyester fiber fabric.

[0033] like Figure 4 As shown, the graphene heating layer 18 is covered with an insulating layer made of materials with high temperature resistance and good insulation properties, such as silicone rubber, ceramic fiber woven fabric, and organic foam. The insulating layer is used to prevent the graphene heating layer 18 from damaging the pillowcase fabric and to ensure that the entire graphene heating layer 18 can generate heat normally and stably.

[0034] like Figure 2 and Figure 3 As shown, the pillowcase 1 has a edging 11 around its edge to prevent the edges of the pillowcase 1 from fraying and to improve its lifespan. A loop 15 is located at the bottom of one side of the pillowcase 1 for easy placement onto the pillow core. A power switch 12 is located at one corner of the pillowcase 1 to control the opening and closing of the graphene heating layer 18. A connector 13 is located near the power switch 12, with a groove 14 in the center of the connector 13. The connector 13, in conjunction with the groove 14, facilitates connection between the pillowcase 1 and the temperature controller 2, allowing the temperature controller 2 to control the heating of the graphene heating layer 18 inside the pillowcase 1.

[0035] like Figure 5As shown, the temperature controller 2 has a control panel 21 on its upper surface, which facilitates operation. The control panel 21 allows for temperature setting, including a temperature setting knob with three settings: low, medium, and high, corresponding to temperatures of 45℃, 50℃, and 55℃ respectively. The control panel 21 also has a time setting knob for setting heating and heat preservation times. Some control panels 21 also include a display screen and a human infrared pyroelectric sensor. The display screen has two functions: displaying temperature and other data, and providing a night light function when illuminated. The human infrared pyroelectric sensor can be a model HC-SR501 with a sensing distance of approximately 20cm. When a user wants to activate the heating function at night, their hand approaching the control panel 21 will be detected by the human infrared pyroelectric sensor, which will transmit a signal to the MCU control module. Upon receiving the signal, the MCU control module will control the display screen to light up, providing the night light function for user convenience. The temperature controller 2 has a connecting wire 22 at one end, and a connecting plug 23 at the other end of the connecting wire 22. The connecting plug 23 connects to the insertion slot 14. This structure facilitates the connection of the connecting wire 22 and the connecting plug 23 to the pillowcase 1. A groove is provided on the bottom wall of the temperature controller 2, and a suction cup is installed in this groove. The suction cup end extends beyond the groove, allowing the temperature controller 2 to be attached to the bedside table panel. Meanwhile, the connecting wire 22 uses a spring wire, which effectively prevents power outages caused by pillow movement. The other end of the temperature controller 2 has a connecting wire 24, and a connecting plug 25 at the other end of the connecting wire 24. The connecting wire and the connecting plug 25 facilitate connection to an external power source.

[0036] like Figure 7 As shown, the constant temperature control module includes a temperature control execution unit, a data receiving unit, and a power adjustment unit. The temperature control execution unit is used to control the graphene heating layer 18 to perform constant temperature heating, the data receiving unit is used to receive data from the temperature sensor, and the power adjustment unit is used to adjust the heating power of the graphene heating layer 18 according to the requirements of constant temperature control.

[0037] like Figure 8 As shown, the over-temperature warning module includes an audible alert unit, a power-off unit, and an illuminated warning unit. The audible alert unit emits a warning sound, the power-off unit cuts off the power supply to ensure that the graphene heating layer 18 is powered off when over-temperature occurs, and the illuminated warning unit emits a warning light to alert users to the danger of over-temperature.

[0038] like Figure 8As shown, it also includes a power supply module with overcurrent, overvoltage, and short-circuit protection circuits to facilitate timely power cut-off in case of abnormalities, preventing the graphene heating layer 18 from burning out. The power supply module also includes a pluggable and removable backup battery to power the pillowcase 1 when external power is unavailable.

[0039] Working Principle: In use, place pillowcase 1 over the pillow core according to your needs and connect temperature controller 2 to pillowcase 1. Then, connect temperature controller 2 to power and set the heating temperature of graphene heating layer 18 via its control panel 21. Once the temperature of pillowcase 1 reaches the set temperature, the constant temperature control module intervenes, adjusting the heating power of the graphene through the power regulation unit to ensure that the heating rate and heat dissipation rate of the graphene are balanced, thus maintaining a constant temperature for the graphene heating layer 18. If the graphene heating layer 18 experiences abnormal temperature rise, the over-temperature warning module will intervene, emitting an audible warning and illuminating an indicator light, while simultaneously cutting off the power to ensure the safe use of pillowcase 1.

[0040] In summary, compared with existing technologies, this application enables the heated pillowcase 1 to have a heating function by setting a graphene heating layer 18, and simultaneously includes a temperature controller 2 to regulate the heat generated by the heated pillowcase 1. The temperature controller 2 also includes a constant temperature control module and an over-temperature warning module. The constant temperature control module can control the pillowcase 1 to maintain a constant temperature. When the pillowcase 1 overheats abnormally, causing a rapid increase in temperature, the over-temperature warning module will intervene, alerting the user through sound and light, and cutting off the power supply through a power-off unit to prevent the temperature from continuing to rise and triggering a piston, effectively ensuring the safe use of the pillowcase 1.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
