Description

Heating control method, system using the same, and mattress Technical Field

[0001] The present invention relates to the field of bedding, and in particular to a heating control method and a system and a mattress using the same. Background Art

[0002] Existing mattresses have a heating function and include a mattress body and a heating layer disposed within the mattress body. The heating layer covers the top surface of the mattress body to increase the temperature of the top surface of the mattress body. The existing heating layer is connected to an external power source via a wire with a switch, and the switch controls the start and stop of the heating layer and its operating state. Existing heating layers have the following defects:

[0003] Each area of ​​the heating layer is controlled by a switch and operates in a unified manner. It is impossible to control the corresponding area for differentiated operation according to the user's lying area, so that the area of ​​the heating layer where the user is not lying will also generate heat, resulting in increased energy consumption. At the same time, each area of ​​the heating layer will generate balanced heat, and the temperature cannot be accurately adjusted according to the differentiated needs of different parts of the user's body. It can only be roughly adjusted by controlling the output heat through the switch, affecting the user experience.

[0004] The heating layer only has an on-off function and cannot provide users with a temperature adjustment solution that is conducive to sleep. As a result, users are easily affected by uncomfortable temperatures and their sleep state is affected, affecting the user experience. Summary of the Invention

[0005] In order to address the shortcomings of the existing technology, the present invention provides a heating control method and a system and mattress using the same, which are equipped with a temperature collection layer, a pressure detection layer, a heating layer and a sleep state detection element. The pressure detection layer can be used to detect the user's lying area, facilitating the cooperation between the heating layer and the temperature collection layer to accurately control the temperature of the user's lying area and reduce energy consumption. The sleep state detection element can also detect the user's sleeping state and control the heating layer to adjust the temperature, thereby improving the user's sleeping comfort and enhancing the user experience.

[0006] The present invention is implemented in the following manner: A heating control method includes a vertically stacked temperature acquisition layer, a pressure detection layer, a heating layer, and a sleep state detection element, and the heating control method is implemented by the following steps:

[0007] Step 1: The user lies down, and the pressure detection layer obtains the user's lying area through the pressure state of each area;

[0008] Step 2: Delineating a main heating zone on the heating layer vertically corresponding to the user's lying area. The main heating zone is divided into a head-shoulder zone, a waist-hip zone, and a leg zone based on the user's body segment proportions. Differentiated heating stimulation is provided to the corresponding body segments of the user through the head-shoulder zone, the waist-hip zone, and the leg zone.

[0009] Step 3: Taking the main heating zone as a reference, the auxiliary heating zones are demarcated on the heating layer and are located on both sides of the main heating zone. The auxiliary heating zones and the main heating zone are subjected to synchronous temperature adjustment control;

[0010] Step 4: Detect the user's sleep stage through the sleep state detection component and implement differentiated temperature adjustment control in each sleep stage.

[0011] The pressure detection layer is used to detect the user's lying area and delineate the main heating area and the secondary heating area on the heating layer. The heating layer cooperates with the temperature collection layer to accurately control the temperature of the main heating area and the secondary heating area. It can not only reduce energy consumption by controlling the local temperature rise of the heating layer, but also detect the user's sleeping state through the sleep state detection element and control the temperature adjustment of each area of ​​the heating layer to facilitate the user to fall asleep and enter a deep sleep state, effectively improve sleep and enhance the user experience. The pressure detection layer can perform pressure detection after the user lies down, and there is no need to perform preparatory operations before the user lies down. It not only simplifies the process and facilitates control, but also ensures the accuracy of the detection of the user's lying area. Setting up a secondary heating zone can provide space for the user to turn over and move to complete preheating, effectively improving the user experience.

[0012] Preferably, in step one, a pressure threshold is set, and when the pressure value received by the pressure detection unit is greater than the pressure threshold, it switches to a triggered state, and the pressure detection units in the triggered state are statistically summarized to form the user lying area. By setting the pressure threshold to prevent false triggering, it is ensured that the obtained user lying area is consistent with the user's actual lying range, and it can also effectively prevent the pressure detection unit from being falsely triggered due to being pressed by foreign objects. The pressure detection unit is triggered when the vertical pressure received by the pressure detection unit is greater than the pressure threshold, and the triggered pressure detection units are summarized to obtain the user lying range, thereby forming the user lying area.

[0013] Preferably, the pressure detection layer includes pressure detection units arranged in a matrix of M columns × N rows, with the coordinates of each pressure detection unit being [m, n]. The column-wise values ​​within the coordinates of the trigger state pressure detection units are sorted and compared to obtain a pressure column-wise range of [m-min, m-max]. The row-wise values ​​within the coordinates of the trigger state pressure detection units are sorted and compared to obtain a pressure row-wise range of [n-min, n-max]. This is used to define a square user lying area on the pressure detection layer, where 1≤m≤M, 1≤n≤N. The pressure detection layer includes pressure detection units arranged in a matrix shape to ensure that each area of ​​the heating layer can sense whether it is squeezed by the user through the corresponding pressure detection units. The pressure detection units are arranged in a matrix shape, which facilitates numbering and marking of the specific rows and columns where each pressure detection unit is located, and is then used to mark the user lying area.

[0014] Preferably, in step 2, the heating layer includes heating sheets arranged in a J-column × K-row matrix, the parameter M is x times the parameter J, and the parameter N is y times the parameter J. The pressure detection units are mapped on each heating sheet to form an x×y matrix layout, and the heating column range [m-min / x, m-max / x] and the heating row range [n-min / y, n-max / y] on the heating layer are obtained, and a square main heating area is delineated on the heating layer. The corresponding main heating area is delineated according to the user's lying area to ensure that the user's vertical projection falls completely within the main heating area, which not only ensures that all parts of the user's body can be effectively heated, but also reduces energy consumption by reducing the area of ​​the main heating area. The heating layer and the pressure detection layer are vertically stacked, and multiple pressure detection units are set in a single heating sheet. By increasing the setting density of the pressure detection units, the detection accuracy is improved, thereby preventing the pressure area of ​​the heating sheet from being vertically misaligned with the pressure detection units on it, resulting in the heating sheet not being included in the main heating area. The pressure detection units are arranged in a matrix on the single heating plate, which facilitates mapping each pressure detection unit to the corresponding heating plate, thereby simplifying the calculation process of converting the user lying area to the main heating area.

[0015] Preferably, in step 2, the heating plates are numbered from 1 to K from front to back, 1≤n-min / y≤n-max / y≤K, and a row difference parameter △H=(n-max / y)-(n-min / y) is set. △H is divided by preset head-shoulder partition, waist-hip partition, and leg section ratios, so that the heating plates are divided into head-shoulder partition, waist-hip partition, and leg section. The front-to-back length ratios of the head-shoulder partition, waist-hip partition, and leg section are preset, and the main heating area is divided from front to back, so that the user's head and shoulders, waist and hip, and legs can be subjected to differentiated heating stimulation by the corresponding head-shoulder partition, waist-hip partition, and leg section, respectively.

[0016] Preferably, when the parameters m-min / x, m-max / x, n-min / y, and n-max / y are non-integer values, they are rounded up. This rounding up allows the calculated result to be directly converted into the serial number corresponding to the heating plate, which not only effectively simplifies the calculation process but also ensures that the pressure detection unit can trigger the corresponding heating plate to energize and generate heat after being squeezed, so that the main heating area on the heating layer can cover the user's lying area.

[0017] Preferably, the temperature collection layer includes temperature collection units arranged in a matrix, each corresponding to one of the heating plates. The temperature collection units can detect the temperature of each heating plate and precisely control the temperature by turning the heating plates on and off. This allows each heating plate to implement differentiated temperature control for its corresponding body segment, enhancing user comfort.

[0018] Preferably, the heating plates are numbered from 1 to J from left to right, 1≤m-min / x≤m-max / x≤J. In step three, the heating layer includes secondary heating zones arranged on both sides of the main heating zone, and the column difference parameter △L=(m-max / x)-(m-min / x) is set. The number of columns of heating plates in the secondary heating zones does not exceed △L. Secondary heating zones are set on both sides of the main heating zone to cope with body movements such as user turning and moving. The secondary heating zones are pre-heated so that the user will not be affected by the low temperature after turning and moving to the secondary heating zones. △L is the number of heating plate columns in the main heating zone, which is used to represent the width of the main heating zone. The width of the secondary heating zone does not exceed the width of the main heating zone. This ensures that the user can still obtain effective heating after turning over, and also limits energy consumption by limiting the number of operating heating plates.

[0019] Preferably, in step 4, the user sets a basal temperature initial value TC and a low temperature threshold value T-min, where T-min ≤ TC. During use, the basal temperature T fluctuates within the range of T-min to TC after reaching TC. The user sets the basal temperature initial value TC as the basis for subsequent temperature control. The low temperature threshold value T-min is obtained by multiplying the basal temperature initial value TC by a coefficient. This can not only improve sleep quality through subsequent temperature fluctuations, but also meet users' differentiated temperature needs and enhance the user experience.

[0020] Preferably, the temperatures of the head and shoulders, waist and hip, and leg zones are set to T1, T2, and T3, respectively, and corresponding conversion coefficients k1, k2, and k3 are set: T1 = T × k1, T2 = T × k2, and T3 = T × k3. The temperatures of the head and shoulders, waist and hip, and leg zones change synchronously, but the specific data needs to be converted using the conversion coefficients so that the temperatures of each zone have the same change trend, thereby improving the sleep-aiding effect through unified temperature changes.

[0021] Preferably, the sleep stage includes a sleep preparation stage, during which T is heated to TC at a preset heating rate and maintained for a duration of Tup, 15mins≤Tup≤25min; or, the sleep stage includes a single sleep cycle sleep stage, during which T is cooled to T-min at a preset low rate and maintained for a duration of Tdown, 30mins≤Tdown≤70min; or, a high temperature threshold T-max is set, T-min≤T-max≤TC, and the sleep stage includes a whole night sleep cycle stage, during which T is first heated to T-max at a preset rate, and then T is reduced to T-min according to the user's sleep state, wherein, when the user is not in a deep sleep state, T is cooled to T-min at a preset low rate and maintained, and when the user is in a deep sleep state, T is cooled to T-min at a preset high rate and maintained; or, the sleep stage includes a wake-up preparation stage, during which T is heated to T-max at a preset heating rate until the user wakes up. The sleep state detector captures the user's sleep state information and adjusts it according to a preset plan, guiding the user into a deep sleep state. As the user falls asleep, the temperature of the heating layer first rises to TC, then drops to T-min, and finally fluctuates between T-min and T-max. Since cooling can drive the user into a deep sleep state, setting the temperature to TC not only provides a warm and comfortable environment for the user preparing to fall asleep, facilitating sleep, but also provides a larger cooling space for the subsequent cooling to T-min, facilitating the user's entry into a deep sleep state, and ensuring that the T-min value after cooling does not affect sleep comfort due to being too low.

[0022] A system using the heating control method includes a control module, a temperature acquisition module, a pressure detection module, a heating module, a sleep state detection module, and a storage module. Specifically, the control module uses the pressure detection module to demarcate a primary heating zone and a secondary heating zone, and divides the primary heating zone into a head-shoulder zone, a waist-hip zone, and a leg zone. The temperature acquisition module detects the temperatures of the head-shoulder zone, the waist-hip zone, and the leg zone, and implements differentiated temperature regulation and control through the heating module. The temperature acquisition module is used to detect the temperature of the corresponding zone and transmit a temperature signal to the control module. The pressure detection module is used to detect the pressure state and transmit a pressure signal to the control module. The heating module receives the heating signal from the control module and is powered on to generate heat. The sleep state detection module is used to detect the user's sleep state and transmit a sleep state signal to the control module. The storage module is used to store parameters related to the control method.

[0023] During use, the control module first defines the user's lying area by receiving pressure signals and calculates the main heating area, and then controls the heating module to implement differentiated temperature adjustment control on the head and shoulder area, waist and hip area, and leg area by receiving temperature signals and sleep status signals.

[0024] A mattress using the aforementioned heating control method comprises a cushion body and an outer cover enclosing the cushion body. The cushion body comprises a temperature collection layer, a heating layer, a pressure detection layer, a sleep sensor, and a support layer stacked in sequence from top to bottom. The temperature collection layer, heating layer, and pressure detection layer can all cover at least the middle area of ​​the top surface of the support layer. By increasing the laying area, the user is ensured to remain in the heated and temperature-controlled area after flipping or moving, effectively improving the user experience. The support layer provides comfortable support for the user, ensuring that the top surface of the cushion body maintains contact with the bottom surface of the user through deformation, which facilitates the transfer of heat from the heating layer to the user.

[0025] The outstanding beneficial effects of the present invention are: using the pressure detection layer to detect the user's lying area and demarcate the main heating area and the secondary heating area on the heating layer. The heating layer cooperates with the temperature collection layer to accurately control the temperature of the main heating area and the secondary heating area. It can not only reduce energy consumption by controlling the local temperature rise of the heating layer, but also detect the user's sleeping state through the sleep state detection element and control the temperature adjustment of each area of ​​the heating layer to facilitate the user to fall asleep and enter a deep sleep state, effectively improve sleep, and enhance the user experience. The pressure detection layer can perform pressure detection after the user lies down, without the need for preparatory operations before the user lies down. This not only simplifies the process and facilitates control, but also ensures the accuracy of the detection of the user's lying area. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Specific embodiment 10

[0034] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0035] Example 1:

[0036] This embodiment provides a heating control method.

[0037] A heating control method as shown in Figures 1 and 2 includes a vertically stacked temperature collection layer, a pressure detection layer, a heating layer, and a sleep state detection element. The pressure detection layer is used to detect the user's lying area and demarcate the main heating area 9 and the secondary heating area 10 on the heating layer to match the user's lying area. The sleep state detection element is then used to detect the user's sleeping state and control the main heating area 9 and the secondary heating area 10 to implement temperature control operations according to a preset plan. This can not only reduce energy consumption by controlling the local temperature rise of the heating layer, but also detect the user's sleeping state through the sleep state detection element and control the temperature adjustment control of each area of ​​the heating layer to facilitate the user to fall asleep and enter a deep sleep state, effectively improve sleep, and enhance the user experience. The pressure detection layer can perform pressure detection after the user lies down, without the need for preparatory operations before the user lies down. This simplifies the process, facilitates control, and ensures the accuracy of the user's lying area detection.

[0038] In this embodiment, the heating control method is implemented by the following steps:

[0039] In step one, the user lies down, and the pressure detection layer determines the user's lying area by measuring the pressure applied to each area. The pressure detection layer activates and performs pressure detection after the user lies down. Compared to air pressure detection, this layer requires no pre-calibration, making it easier to use.

[0040] In step one, a pressure threshold is set. When the pressure value received by the pressure detection unit is greater than the pressure threshold, it switches to a trigger state. The pressure detection units in the trigger state are statistically summarized and form the user lying area. Setting the pressure threshold can not only effectively avoid the situation where the pressure detection unit is falsely triggered due to pressure from foreign objects, but also effectively delineate the user lying area, and prepare for differentiated operations in each area of ​​the subsequent heating layer.

[0041] In step 1, the pressure detection layer includes pressure detection units arranged in an M-column x N-row matrix, with the coordinates of each pressure detection unit being [m, n]. The column-wise values ​​within the trigger-state pressure detection unit coordinates are sorted and compared to obtain a column-wise pressure range of [m-min, m-max]. The row-wise values ​​within the trigger-state pressure detection unit coordinates are sorted and compared to obtain a row-wise pressure range of [n-min, n-max]. This is used to delineate a square user reclining area on the pressure detection layer, where 1 ≤ m ≤ M and 1 ≤ n ≤ N. Because the pressure detection units are arranged in a matrix, each pressure detection unit can form calibration coordinates using its row and column values. Specifically, the calibrated coordinates of all triggered pressure detection units are obtained, the row values ​​of the above coordinates are compared, and the maximum value and the minimum value are combined to form a pressure row range [n-min, n-max], and the column values ​​of the above coordinates are compared, and the maximum value and the minimum value are combined to form a pressure column range [m-min, m-max]. The square area thus demarcated forms the user lying area. Since both the row and column directions are demarcated using the maximum range, it is ensured that the user's vertical projection falls completely into the demarcated user lying area.

[0042] Step 2: A main heating zone 9 is defined on the heating layer, vertically corresponding to the user's lying area. This main heating zone 9 is divided into a head-and-shoulder section 11, a waist-and-hip section 12, and a leg section 13 based on the user's torso proportions. Differentiated heating stimulation is provided to each corresponding torso section via these sections. The user's lying area is used to convert and define the main heating zone 9. Based on this main heating zone 9, the head-and-shoulder section 11, the waist-and-hip section 12, and the leg section 13 are defined within the main heating zone 9. Differentiated temperature control is used to provide differentiated heating to each corresponding torso section.

[0043] In step 2, the heating layer includes heating plates arranged in a J-column × K-row matrix, with parameter M being x times parameter J, and parameter N being y times parameter J. The pressure detection units are mapped onto each heating plate to form an x×y matrix layout, and the column-wise heating range [m-min / x, m-max / x] and row-wise heating range [n-min / y, n-max / y] on the heating layer are obtained, which are then used to define a square main heating area 9 on the heating layer. Because the density of the pressure detection units is greater than the density of the heating plates within the heating layer, when the heating layer and the pressure detection layer are stacked, multiple pressure detection units arranged in an x×y matrix will fall into a single heating plate, so that the coordinate values ​​of the pressure detection units and the coordinate values ​​of the heating plates can be converted using the parameters x and y, respectively. For example, the pressure detection units in a single heating plate are arranged in a 2×2 matrix. When m-min=8, the column-oriented value of the corresponding heating plate coordinate is 8 / 2=4. Similarly, the parameters n-min, n-max, and m-max can be calculated to obtain the column-oriented parameters and row-oriented parameters of the corresponding heating plate coordinates. The heating plate corresponding to the calculated coordinates is set as the boundary of the main heating area 9, and the square main heating area 9 is demarcated thereby.

[0044] In step 2, the parameters m-min / x, m-max / x, n-min / y, and n-max / y are used to form the column parameters and row parameters of the heating plate coordinates. Since a single heating plate is provided with multiple pressure detection units, the column parameters and row parameters may not be integers. In order to facilitate the formation of the heating plate coordinates, the non-integer parameters are rounded up to ensure that the heating plate will be triggered to generate heat by any of the pressure detection units on it, and the main heating area 9 can completely cover the user's lying area. The fault tolerance performance is improved by appropriately expanding the range of the main heating area 9 to meet usage requirements.

[0045] In step 2, the heating plates are numbered from front to back, 1 to K, with 1 ≤ n-min / y ≤ n-max / y ≤ K. A row difference parameter ΔH is set to (n-max / y) - (n-min / y). ΔH is divided according to the preset ratios between the head-shoulder zone 11, waist-hip zone 12, and leg zone 13, so that the heating plates are divided into the head-shoulder zone 11, waist-hip zone 12, and leg zone 13. The main heating zone 9 is divided from front to back into the head-shoulder zone 11, waist-hip zone 12, and leg zone 13 (as shown in FIG3 ). The ratio of the front-to-back lengths of the head-shoulder zone 11, waist-hip zone 12, and leg zone 13 is preferably 4:5:6. When the vertical lengths of the divided zones cannot be rounded up, they are rounded up to ensure that the heating plates do not cross between adjacent zones, thereby ensuring that each heating plate has a unified temperature control scheme.

[0046] In step 2, the temperatures of the head-shoulder zone 11, waist-hip zone 12, and leg zone 13 are set to T1, T2, and T3, respectively. Conversion coefficients k1, k2, and k3 are set for each of these zones: T1 = T × k1, T2 = T × k2, and T3 = T × k3. While the head-shoulder zone 11, waist-hip zone 12, and leg zone 13 are heated or cooled simultaneously, temperature differences may exist between these zones due to their corresponding torso segments. Setting conversion coefficients facilitates achieving the appropriate temperature for each zone, facilitating control operations and providing differentiated heating for each torso segment, effectively improving comfort. The temperature control scheme changes with the user's sleep state, and the base temperature T changes accordingly. By setting conversion coefficients k1, k2, and k3, the parameters T1, T2, and T3 are linked to the base temperature T, effectively controlling the temperatures of the head-shoulder zone 11, waist-hip zone 12, and leg zone 13. The values ​​of the conversion coefficients k1, k2, and k3 are between 0.7 and 1, and the specific parameters can be adjusted according to the user's habits and preferences.

[0047] Step three, taking the main heating zone 9 as the reference, demarcate the secondary heating zones 10 on both sides of the main heating zone 9 on the heating layer, and the secondary heating zones 10 and the main heating zone 9 are synchronously controlled to adjust the temperature. Based on the main heating zone 9, secondary heating zones 10 are demarcated on both sides of the main heating zone 9. The secondary heating zones 10 are synchronously controlled with the main heating zone 9 to preheat the areas where the user may lie down after turning over, ensuring that the user can get effective heating even after turning over and moving. Specifically, the secondary heating zone 10 is also divided into a head and shoulder zone 11, a waist and hip zone 12, and a leg zone 13, and the temperature control operation is performed according to a preset plan, so that each body segment of the user always gets a uniform heating experience after turning over.

[0048] In step three, the heating plates are numbered from left to right from 1 to J, where 1≤m-min / x≤m-max / x≤J. The heating layer includes secondary heating zones 10 disposed on either side of the primary heating zone 9. A column difference parameter ΔL is set equal to (m-max / x)-(m-min / x). The number of columns of heating plates within the secondary heating zones 10 does not exceed ΔL. Secondary heating zones 10 are disposed on either side of the primary heating zone 9, with the width of each secondary heating zone 10 not exceeding the width of the primary heating zone 9. For example, when the primary heating zone 9 spans four columns of heating plates laterally, and when there are four or more columns of heating plates between the side edges of the primary heating zone 9 and the corresponding side edges of the heating layer, a secondary heating zone 10 is provided that is closely connected to the primary heating zone 9 and spans four columns of heating plates laterally. When there are no more than three columns of heating plates between one side of the primary heating zone 9 and the corresponding edge of the heating layer, a secondary heating zone 10 is provided in the area between the primary heating side edge and the corresponding side edge of the heating layer to form the secondary heating zone 10.

[0049] Step 4: Detect the user's sleep stage through the sleep state detection component, and implement differentiated temperature adjustment control in each sleep stage. The temperature acquisition layer includes temperature acquisition units arranged in a matrix shape, and the temperature acquisition units are set corresponding to the heating plates one by one. By detecting the temperature of each heating plate through the temperature acquisition unit, the temperature control accuracy can be improved by controlling the on and off switching of the heating plate, and it can also ensure that the heating plate can effectively execute the preset temperature control scheme when it is divided into different partitions, thereby improving the control reliability. By setting a sleep state detection component to perceive the user's sleep state in real time and provide a basis for temperature control operations, the temperature can be adjusted according to the user's sleep state, effectively improving the sleep experience.

[0050] In step 4, the user sets the base temperature initial value TC and the low temperature threshold T-min, where T-min ≤ TC. During use, the base temperature T fluctuates within the range of T-min to TC after reaching TC. Users can pre-set the base temperature initial value TC based on their heating preferences, ensuring that the temperature changes of the heating layer always follow the user's preferred temperature, preventing excessive temperature deviations that affect the user experience.

[0051] In step 4, the user's sleep state includes the preparation for falling asleep, the single sleep cycle falling asleep, the full night sleep cycle cycle, and the awakening preparation stage. Different temperature adjustment operations are performed for users in different sleep states. The parameter T will be adjusted according to the preset plan and converted into parameters T1, T2, and T3 to control the temperature of each zone, as shown in Figure 4. Specifically:

[0052] When the user is preparing to fall asleep, T is raised to TC at a preset rate and maintained for a duration of Tup, 15 minutes ≤ Tup ≤ 25 minutes. Specifically, the temperature change during this stage is in preparation for falling asleep. By increasing parameter T to TC, room is reserved for cooling later. Parameter T is raised to TC at a preset rate and maintained until the duration is reached, at which point the user enters the single sleep cycle stage.

[0053] When the user is in the sleep phase of a single sleep cycle, the temperature T is lowered to T-min at a preset low rate and maintained there for a duration of Tdown, with a duration of 30 minutes ≤ Tdown ≤ 70 minutes. As the body prepares for deep sleep, its body temperature drops due to factors such as decreased metabolism, heart rate, and blood flow, until it reaches its lowest point just before deep sleep. The temperature T is lowered to T-min at a preset low rate and maintained there. This lowers the body temperature, promoting deep sleep and improving sleep quality.

[0054] When the user is in the sleep cycle stage of the whole night, a high temperature threshold T-max is set, T-min≤T-max≤TC. During this stage, T is first heated to T-max at a preset rate, and then T is reduced to T-min according to the user's sleep state. By heating up, space is provided for subsequent cooling. The cooling operation not only prompts the user to enter a deep sleep state again, but also ensures that T-min is not too low, ensuring the user's sleep comfort. Specifically, when the user is not in a deep sleep state, T is cooled to T-min at a preset low rate and maintained. By slowing down the cooling speed, the cooling time is prolonged, which is conducive to the user entering a deep sleep state; when the user is in a deep sleep state, T is cooled to T-min at a preset high rate and maintained. By quickly cooling to T-min, the user is ensured to maintain a deep sleep state, preventing the user from leaving the deep sleep state, and improving sleep quality by extending the deep sleep state. This stage is executed periodically, effectively increasing the proportion of deep sleep time in the total sleep time of the whole night.

[0055] When the user is in the wake-up preparation stage, during this stage, T is heated up to T-max at a preset heating rate until the user wakes up, which is beneficial for the user to get out of deep sleep and increase the user's body temperature in preparation for getting up.

[0056] Example 2:

[0057] Compared with the first embodiment, this embodiment provides a system.

[0058] A system using the heating control method includes a control module, a temperature acquisition module, a pressure detection module, a heating module, a sleep state detection module, and a storage module. Specifically, the control module uses the pressure detection module to demarcate a primary heating zone 9 and a secondary heating zone 10, and divides the primary heating zone 9 into a head-shoulder zone 11, a waist-hip zone 12, and a leg zone 13. The temperature acquisition module detects the temperatures of the head-shoulder zone 11, the waist-hip zone 12, and the leg zone 13, and implements differentiated temperature regulation and control through the heating module. The temperature acquisition module is used to detect the temperature of the corresponding zone and transmit a temperature signal to the control module. The pressure detection module is used to detect the pressure state and transmit a pressure signal to the control module. The heating module receives the heating signal from the control module and is powered on to generate heat. The sleep state detection module is used to detect the user's sleep state and transmit a sleep state signal to the control module. The storage module is used to store parameters related to the control method.

[0059] When in use, the control module first determines the user's lying area by receiving pressure signals and calculates the main heating zone 9, the secondary heating zone 10, and the head and shoulder partition 11, the waist and hip partition 12, and the leg partition 13 set in the main heating zone 9, and then controls the heating module to implement differentiated temperature adjustment control on the head and shoulder partition 11, the waist and hip partition 12, and the leg partition 13 by receiving temperature signals and sleep status signals.

[0060] In this embodiment, the storage module stores the software program required to run the heating control method and the parameters involved, including but not limited to the conversion coefficient, pressure threshold, basic temperature initial value TC, high temperature threshold T-max, low temperature threshold T-min, etc., to ensure the effective implementation of the control method.

[0061] The other features and effects of the heating control method described in this embodiment are consistent with those of the first embodiment and will not be repeated here.

[0062] Example 3:

[0063] Compared with the first embodiment, this embodiment provides a mattress.

[0064] The mattress shown in Figures 5 and 6 comprises a cushion body and an outer cover enclosing the cushion body. The cushion body comprises a temperature collection layer, a heating layer, a pressure detection layer, a sleep sensor, and a support layer stacked in order from top to bottom. A control box is located within the support layer. This box receives signals from the temperature collection layer, the pressure detection layer, and the sleep sensor, and controls the independent operation of the heating elements within the heating layer, thereby enabling independent temperature regulation within the head-shoulder zone 11, the waist-hip zone 12, and the leg zone 13.

[0065] In this embodiment, the vertical projections of the temperature collection layer, the heating layer, and the pressure detection layer overlap and cover the top surface of the support layer, ensuring that each area of ​​the mattress body can be designated as a user lying area and provide corresponding heating operations.

[0066] In this embodiment, a single heating plate is covered with four pressure detection units arranged in a 2×2 matrix. The temperature acquisition layer includes a temperature sensor covering the center of each heating plate to ensure that the temperature of each heating plate is controllable. In addition, the arrangement density of the heating plates, temperature sensors, and pressure detection units can be adjusted as needed and should be considered as a specific implementation of this embodiment.

[0067] The other features and effects of the heating control method described in this embodiment are consistent with those of the first embodiment and will not be described in detail.
