[0051] Such as Figures 1 - 8As shown in the figure, in this embodiment, the temperature-adjustable bed screen includes a housing 1, an air cotton 2, a partition assembly 3, a ventilation duct 4, a hot air blower 5, a switch 6, and a temperature control assembly 7. Among them, the air cotton 2 and the housing 1 enclose a receiving cavity. The partition assembly 3 includes a first partition 31 and a second partition 32. The first partition 31 and the second partition 32 are respectively arranged in the receiving cavity along the horizontal direction and the height direction. The first partition 31 divides the receiving cavity into a first cavity 11 and a second cavity 12. The second partition 32 is located in the first cavity 11 and divides it into a confluence cavity 111 and a receiving cavity 112. The ventilation duct 4 is arranged in the second cavity 12. The ventilation duct 4 has a first end and a second end. The first end of the ventilation duct 4 communicates with the confluence cavity 111. The second end of the ventilation duct 4 and the confluence cavity 111 are respectively communicated with both ends of the air cotton 2. The ventilation duct 4 is provided with an air inlet 41 and an air outlet 42. The hot air blower 5 is arranged at the second end of the ventilation duct 4. The switch 6 is arranged in the ventilation duct 4 between the air inlet 41 and the air outlet 42. The temperature control assembly 7 includes a temperature control device 71 and a control module 72 electrically connected to the temperature control device 71. The temperature control device 71 is arranged in the first cavity 11. The temperature control device 71 is used to detect the temperature of the air cotton 2. The control module 72 is used to control the hot air blower 5, the air inlet 41, the air outlet 42, and the switch 6 to be opened or closed. Specifically, a notch is provided on the bed screen surface of the housing 1. The air cotton 2 is arranged at the notch and is used to support the human back and head. The air cotton 2 replaces the traditional sponge, which can not only achieve the effects of softness and high resilience, but also better circulate air. The hot air blower 5 is arranged inside the ventilation duct 4 and is used to heat the gas flowing in the ventilation duct 4 and flow it to the air cotton 2, so as to heat the human back and head. The switch 6 can be opened or closed to open or block the gas flowing in the ventilation duct 4 between the air inlet 41 and the air outlet 42. The control module 72 electrically connected to the temperature control device 71 is an electronic control master box, which opens or closes the hot air blower 5, the air inlet 41, the air outlet 42, and the switch 6 through the temperature signal detected by the temperature control device 71.

[0052] The working principle of the adjustable-temperature bed screen is as follows: Turn on the temperature control device 71 and adjust it to the set temperature. When the temperature control device 71 detects that the temperature of the air cotton 2 has not reached the set temperature, the temperature control device 71 sends a high level to the control module 72. The control module 72 can control the hot air blower 5 to start working, close the air inlet 41 and the air outlet 42, and open the opener 6. At this time, the bed screen is in the internal circulation mode, that is, the hot air blower 5 heats the air in the ventilation duct 4 and reaches the bottom of the air cotton 2 through the second end of the ventilation duct 4, and then heats it through the air cotton 2. According to the requirement of the set temperature, a certain temperature of heating is carried out on the back and head of the human body. The warm air flowing in the air cotton 2 successively passes through the confluence chamber 111 and the first end of the ventilation duct 4 and reaches the inside of the ventilation duct 4, and flows to the hot air blower 5 through the opened opener 6. The warm air is heated by the hot air blower 5 again and continues to circulate along the above route. When the temperature control device 71 detects that the temperature of the air cotton 2 reaches the set temperature, the temperature control device 71 sends a low level to the control module 72. The control module 72 can control the hot air blower 5 to stop heating and operate at low power, so that the air cotton 2 is in a constant temperature state. When it is necessary to reduce the temperature, the air inlet 41 and the air outlet 42 are opened, and the opener 6 is closed. At this time, the bed screen is in the external circulation mode. Under the action of the hot air blower 5, the air in the external environment is drawn into the ventilation duct 4 through the air inlet 41, successively passes through the hot air blower 5, the air cotton 2, and the confluence chamber 111 and returns to the ventilation duct 4, and finally is discharged through the air outlet 42, so as to reduce the temperature of the air cotton 2. The temperature of the bed screen is adjusted according to the climate temperature to meet the needs of each person for the bed screen temperature under different climates, with high comfort and diverse requirements.

[0053] Further, continue to refer to Figures 1 - 8 and the adjustable-temperature bed screen further includes a blower 10. The blower 10 is arranged at the air outlet 42, and the blower 10 is electrically connected to the control module 72. Specifically, when the temperature control device 71 detects that the temperature of the air cotton 2 has not reached the set temperature, the temperature control device 71 sends a high level to the control module 72. The control module 72 can control the blower 10 at the air outlet 42 to close, prohibiting the warm air from being discharged through the air outlet 42. When the temperature control device 71 detects that the temperature of the air cotton 2 reaches the set temperature and it is necessary to reduce the temperature, the temperature control device 71 sends a low level to the control module 72. The control module 72 can control the blower 10 at the air outlet 42 to open, so that the warm air inside the bed screen is discharged through the air outlet 42 under the action of the blower 10.

[0054] Further, continue to refer to Figures 1 - 8, the temperature-adjustable bed screen further includes an exhaust fan 20, which is disposed at the air inlet 41 and electrically connected to the control module 72. Specifically, when the temperature control device 71 detects that the temperature of the air cotton 2 has not reached the set temperature, the temperature control device 71 sends a high level to the control module 72, and the control module 72 can control the exhaust fan 20 at the air inlet 41 to close, prohibiting the air from the external environment from entering through the air inlet 41. When the temperature control device 71 detects that the temperature of the air cotton 2 reaches the set temperature and needs to be reduced, the temperature control device 71 sends a low level to the control module 72, and the control module 72 can control the exhaust fan 20 at the air inlet 41 to open, so that the air from the external environment is drawn into the ventilation duct 4 through the air inlet 41 under the action of the exhaust fan 20, facilitating the discharge of the warm air in the bed screen to achieve the effect of rapid cooling.

[0055] Further, with continued reference to Figures 1 - 8 , the temperature-adjustable bed screen further includes a ventilator 30, which is disposed at the first end of the ventilation duct 4. Specifically, the ventilator 30 is always in the open state, facilitating the rapid flow of the warm air in the confluence chamber 111 and the air cotton 2 into the ventilation duct 4 under the action of the ventilator 30 at the first end and being in a cyclic state, achieving a certain promoting effect.

[0056] Further, with continued reference to Figures 1 - 8 , the temperature control device 71 includes a temperature control switch 711 and a temperature sensor 712. The temperature control switch 711 is installed on the housing 1 and electrically connected to the temperature sensor 712. The temperature sensor 712 is installed on the air cotton 2 and electrically connected to the control module 72. Specifically, when the temperature control switch 711 is turned on, the current temperature is displayed on the display board and adjusted to the set temperature. When the temperature sensor 712 detects that the temperature of the air cotton 2 has not reached the set temperature, the temperature sensor 712 sends a high level to the control module 72, and the control module 72 can control the hot air blower 5 to start working, the air inlet 41 and the air outlet 42 are closed, and the opener 6 is opened. At this time, the bed screen is in the internal circulation mode, and the air cotton 2 is in a state of continuous temperature heating. When the temperature sensor 712 detects that the temperature of the air cotton 2 reaches the set temperature, the temperature sensor 712 sends a low level to the control module 72, and the control module 72 can control the hot air blower 5 to stop heating and operate at a low power, so that the air cotton 2 is in a constant temperature state. When the temperature needs to be reduced, the air inlet 41 and the air outlet 42 are opened, and the opener 6 is closed. At this time, the bed screen is in the external circulation mode, so that the temperature of the air cotton 2 drops rapidly.

[0057] Further, with continued reference to Figures 1 - 8, the hot air blower 5 includes a heating part 51 and a ventilation part 52. One end of the heating part 51 is connected to the first end of the ventilation duct 4, the other end of the heating part 51 is connected to one end of the ventilation part 52, and the other end of the ventilation part 52 is connected to the second end of the ventilation duct 4. Specifically, when the temperature control sensor 712 detects that the temperature of the air cotton 2 has not reached the set temperature, the temperature control sensor 712 sends a high level to the control module 72, and the control module 72 can control the heating part 51 and the ventilation part 52 to work simultaneously, heating and promoting the circulation of the air in the ventilation duct 4. When the temperature control sensor 712 detects that the temperature of the air cotton 2 reaches the set temperature, the temperature control sensor 712 sends a low level to the control module 72, and the control module 72 can control the heating part 51 to stop running, and the ventilation part 52 runs at a low power.

[0058] Further, with continued reference to Figures 1 - 8 , the temperature-adjustable bed screen further includes a diversion assembly 8. The diversion assembly 8 has a fan-shaped structure. The diversion assembly 8 has an air inlet end 81 and an air outlet end 82. The air inlet end 81 is connected to the second end of the ventilation duct 4, and the air outlet end 82 is connected to the air inlet end of the air cotton 2. Specifically, the diversion assembly 8 includes a plurality of diversion plates, and the plurality of diversion plates are arranged at intervals in a radial shape, so that the heated air in the ventilation duct 4 is discharged in a divergent shape to each position of the air cotton 2 under the action of the diversion assembly 8, with a wide coverage area, ensuring that the heating area of the air cotton 2 for heating the human back and head is large and uniform.

[0059] Further, with continued reference to Figures 1 - 8 , the temperature-adjustable bed screen further includes a confluence assembly 9. The confluence assembly 9 has a V-shaped structure. The confluence assembly 9 has an inlet end 91 and an outlet end 92. The inlet end 91 is connected to the air outlet end of the air cotton 2, and the outlet end 92 is connected to the first end of the ventilation duct 4. Specifically, the confluence assembly 9 includes two confluence plates, and the two confluence plates are arranged in the confluence cavity 111, and the two confluence plates are combined into a V-shaped structure, that is, the opening of the inlet end 91 of the confluence assembly 9 is large, and the opening of the outlet end 92 is small, so that the heated air in the air cotton 2 flows into the ventilation duct 4 through the inlet end 91 and the outlet end 92 in sequence. The confluence assembly 9 plays a role of confluence, enabling the air in the air cotton 2 to be quickly collected and diverted to the ventilation duct 4.

[0060] This embodiment also provides a bed, which includes a bed body and a bed screen with adjustable temperature. The bed screen with adjustable temperature is arranged at the head end of the bed body. Specifically, different people can adjust the set temperature of the bed screen through the temperature control device 71 according to the current climate temperature conditions. The hot air blower 5 starts to work, and the bed screen is in the internal circulation mode to heat the air cotton 2. The user resting on the bed body can lean on the bed screen, so as to continuously heat the back and head of the human body. When the temperature of the bed screen reaches the set temperature, the hot air blower 5 stops heating and operates at a low power, so that the bed screen is in a constant temperature state. When it is necessary to reduce the temperature, the air inlet 41 and the air outlet 42 are opened, and the opener 6 is closed. At this time, the bed screen is in the external circulation mode, and the air in the external environment is drawn into the ventilation duct 4 through the air inlet 41 and finally discharged through the air outlet 42, so as to reduce the temperature of the bed screen.
