[0002] Nowadays, people live at a fast pace and under great pressure. The quality of sleep is getting worse and worse, with shorter deep sleep time and more night awakenings. How to improve people's sleep quality has also become a research focus of many institutions. Some research papers show that when people are in deep sleep, their body temperature will drop, and a more suitable sleeping environment temperature can help people get better sleep. Electric blankets are a common winter heating device in households. The temperature settings of existing electric blankets are fixed and cannot adapt to the temperature requirements of people in different sleep modes.

[0003] Current electric blankets can only be set to a fixed temperature. Many people will feel irritated and dry after sleeping all night, and will be woken up by the heat in the middle of the night, which greatly reduces the comfort of using electric blankets. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0044] See also Figure 1 and Figure 2 As shown, this embodiment provides an electric blanket with temperature adjustment based on the sleeping state, including a blanket body 100, a controller 200, a temperature sensor 300 and a vibration sensor 400; a heating element is arranged in the blanket body 100, and the heating element is connected to the controller 200 so that the controller 200 can adjust the heating temperature of the heating element; the controller 200 is arranged at the edge of the blanket body 100, and the temperature sensor 300 and the vibration sensor 400 are both connected to the controller 200.

[0045] Specifically, when the user lies on the blanket body 100, the temperature of the heating element can be adjusted through the controller 200 to meet the user's temperature requirements before going to bed. When the user falls asleep, the vibration sensor 400 on the blanket body 100 can identify the human body's sleeping state and automatically adjust the temperature of the electric blanket according to the current sleeping state, so that the user can get a more comfortable sleeping environment and improve sleep quality.

[0046] Among them, the heating element can adopt a heating wire or a heating film or other structures. Those skilled in the art can choose according to actual needs, and will not be described in detail here.

[0047] It should be noted that a touch button is provided on the controller 200 so that the user can operate the controller 200 to perform actions such as temperature adjustment.

[0048] It should also be pointed out that a body surface temperature sensor 600 is provided on the blanket body 100. The body surface temperature sensor 600 can be a thermistor. The body surface temperature sensor 600 is used to detect the body surface temperature of the user. The body surface temperature sensor 600 can be provided in the middle of the blanket body 100. The body surface temperature sensor 600 can detect the body surface temperature of the user. In addition, multiple body surface temperature sensors 600 can be provided, and multiple body surface temperature sensors 600 are arranged in an array, so that the body surface temperature sensor 600 can detect the body surface temperature of the user more accurately. And the controller 200 can adjust the power of the heating element according to the data of the body surface temperature sensor 600. For example, in the sleeping state, if the patient's body surface temperature is detected to be lower than 25 degrees Celsius, the controller 200 controls the heating element to increase the power so that the user's body surface temperature rises to above 25 degrees Celsius.

[0049] It should also be pointed out that the above-mentioned body surface temperature refers to the temperature of the user's body in contact with the blanket body 100, and is used to measure the user's perceived temperature.

[0050] The plurality of body surface temperature sensors 600 are arranged in an array. Through such an arrangement, when a user uses the blanket 100, the user's body surface temperature can be detected by several of the plurality of body surface temperature sensors 600 arranged in the array, thereby obtaining an accurate user's body surface temperature. Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, a plurality of temperature sensors 300 are disposed on the blanket body 100 , and the plurality of temperature sensors 300 are evenly distributed along the length direction of the blanket body 100 .

[0051] The temperature sensor 300 includes a first temperature sensor 310 capable of detecting the temperature inside the quilt, and there are multiple first temperature sensors 310.

[0052] The temperature sensor 300 further includes a second temperature sensor 320 capable of detecting the external environment temperature. The second temperature sensor 320 is disposed at the edge of the blanket body 100 .

[0053] Specifically, after the controller 200 adjusts the temperature of the heating element, the detection result of the first temperature sensor 310 is used as the basis, so that the user can obtain accurate temperature adjustment.

[0054] In addition, when the controller 200 automatically adjusts the temperature according to the vibration sensor 400, the result of the second temperature sensor 320 is referred to when adjusting the temperature of the heating element.

[0055] It should be pointed out that the temperature compensation function is realized by the second temperature sensor 320. 5 minutes after the user switches the switch control for the last time, the controller 200 can obtain the external ambient temperature regularly detected by the second temperature sensor 320, and then compare the temperature of the second temperature sensor 320 with that of the first temperature sensor 310, that is, compare the temperature inside the quilt with the temperature of the environment, and make adjustments based on the average ambient temperature within 5 minutes. For example, when the ambient temperature benchmark is reduced by 2 degrees Celsius, the controller 200 controls the heating element to increase by 2 degrees Celsius. When the ambient temperature benchmark is increased by 2 degrees Celsius, the controller 200 controls the heating element to decrease by 2 degrees Celsius.

[0056] The acquisition frequency of the second temperature sensor 320 may be set to once per second.

[0057] In addition, users can control the opening and closing of the temperature compensation function through the mobile terminal.

[0058] It should also be pointed out that, through the setting of the body surface temperature sensor 600 and the second temperature sensor 320, the controller 200 can also selectively use the ambient temperature as a reference for the controller to adjust the blanket temperature, so as to obtain a more comfortable experience in an environment with a large temperature difference between day and night, and when air conditioning and heating are turned on. The body temperature detection function can also further optimize temperature control based on sleep detection and ambient temperature, thereby improving the user experience.

[0059] See also Figure 1 and Figure 2 As shown, in an optional solution of this embodiment, the vibration sensor 400 is arranged in the upper middle part of the carpet body 100 .

[0060] The blanket body 100 is provided with a user head orientation mark 500 , and the user head orientation mark 500 and the controller 200 are both arranged on the upper part of the blanket body 100 .

[0061] Specifically, a user head orientation mark 500 is provided on the blanket body 100 so that when the user uses the blanket body 100 , the vibration sensor 400 provided in the upper middle part of the blanket body 100 can stably capture the user's movement and ensure accurate judgment.

[0062] This prevents the user's feet or head from being too far away from the vibration sensor 400 when the user curls up, causing the vibration sensor 400 to be unable to effectively capture signals and cause misjudgment.

[0063] See also Figure 1 and Figure 2As shown, in an optional solution of this embodiment, two groups of heating elements are arranged on the blanket body 100, and the two groups of heating elements are separately connected to the controller 200; the two groups of heating elements are symmetrically arranged along the length direction of the blanket body 100, and form a left area 110 and a right area 120 on the blanket body 100;

[0064] The temperature sensor 300 and the vibration sensor 400 are both disposed on the left area 110 and the right area 120 .

[0065] Specifically, a left area 110 and a right area 120 may be provided on the blanket 100, and both the left area 110 and the right area 120 are provided with a temperature sensor 300 and a vibration sensor 400, so that two users lying on the blanket 100 can adjust separately to meet the different needs of the two users.

[0066] See also Figure 3 As shown, this embodiment provides an electric blanket control method based on sleep state temperature adjustment, which is used for the use of an electric blanket based on sleep state temperature adjustment, and includes the following steps: the controller 200 obtains the vibration signal of the vibration sensor 400, and when the controller 200 obtains a high-level vibration signal, it is counted as D=1, and when the controller 200 obtains a low-level vibration signal, it is counted as D=0, and the number of vibrations is counted, the count is S, the counting cycle is 1 second, and the vibration sensor 400 detects once every 20ms; the controller 200 counts S greater than 0, the count is M, and the counting cycle is 1 minute; in not less than When M=0 within 5 minutes, the controller 200 controls the heating element to lower the temperature and enter the light sleep mode. After entering the light sleep mode, when M≥7 or S≥25, the controller 200 releases the light sleep mode; in the light sleep mode, when M=0 within no less than 5 minutes, the controller 200 controls the heating element to lower the temperature and enter the deep sleep mode. When D=1, the deep sleep mode switches back to the light sleep mode; in the deep sleep mode, when M=0 within no less than 60 minutes, the controller 200 controls the heating element to stop working and enter the sleep mode. After entering the sleep mode, when D=1, the controller 200 wakes up and controls the heating element to work.

[0067] The vibration sensor 400 detects once every 20 ms. If vibration is detected, the vibration sensor 400 transmits a high-level signal to the controller 200 . If no vibration is detected, the vibration sensor 400 maintains a low-level transmission to the controller 200 .

[0068] The controller 200 counts the effective vibration signals per second, and the count is S, that is, the controller 200 records the number of vibrations per second S. Then, the number of S times per minute is counted M, that is, how many seconds per minute are vibrations detected.

[0069] In the light sleep mode, the heating element is lowered by 1-3 degrees Celsius; in the deep sleep mode, the heating element is lowered by 3-6 degrees Celsius. In addition, when the controller 200 automatically adjusts the temperature according to the vibration sensor 400, the result of the second temperature sensor 320 is referred to when adjusting the temperature of the heating element.

[0070] In addition, after the controller 200 enters the sleep mode, if the second temperature sensor detects that the ambient temperature continues to drop, the controller 200 will be awakened and control the heating element to increase the temperature to ensure that the user will not wake up due to discomfort caused by the sudden drop in sleeping temperature; in addition, when the first temperature sensor 310 detects that the temperature in the quilt is lower than the set temperature, the controller 200 will also be awakened and control the heating element to increase the temperature.

[0071] It should be noted that when the electric blanket is used, the vibration sensor 400 does not perform detection work within one hour after the controller 200 is turned on.

[0072] In addition, a Bluetooth module is provided in the controller 200 so that the controller 200 can be connected to the user's mobile phone terminal, so that the user can control it through the terminal APP and can set the cooling of the light sleep mode and the deep sleep mode by himself.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
