Usually, one type of pillow cannot be suitable for users with different needs, and its functionality is relatively single. The prior art provides some technical solutions for adjustable pillows, such as using a height adjustment device to inflate or deflate an airbag to adjust the height of the pillow. The pillow can be adjusted to different heights. However, in the prior art, only an airbag is provided at the connection between the head and the neck to adjust the height, and the neck support position cannot be adjusted.

Detailed Embodiments

[0025] Refer to Figures 1-7As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes an elastic pillowcase 1, and a pillow core 2 is arranged inside the elastic pillowcase 1. An elevating mechanism 3 is arranged inside the pillow core 2. In this embodiment, an integral elevating mechanism is arranged inside the pillow core. The elevation of existing intelligent pillows mainly adjusts the height of the head position. This structure is more suitable for adjusting the height of the pillow when the same user is in different sleeping postures. Since the height of the neck cannot be adjusted, the experience is not good when different users use it. Therefore, in this embodiment, an integral elevating structure is arranged to elevate the head and part of the neck position. The pillow core itself is designed with a wave-shaped structure that conforms to ergonomics and is made of high-elastic memory foam material. It can also be designed with a traditional shallow arc surface structure, and users can choose according to different preferences. Generally, the wave-shaped structure can better support the neck, and those with poor sleep quality can choose the pillow core of this structure. Since this type of structure is a conventional design, this embodiment does not limit it too much; when different users adjust the height of the pillow through the elevating mechanism, since the height is lifted simultaneously, the head and neck are lifted simultaneously within a small range, and the curves of the head and neck basically remain unchanged, only the curve of the neck and the body changes, which is more in line with ergonomic design and can improve sleep quality. However, the traditional structure lifts the head but not the neck, which will cause discomfort in the neck and affect sleep quality.

[0026] More specifically, a heating plate 4 is arranged on the elevating mechanism 3 and is electrically connected to the control main board 8 inside the elevating mechanism 3. To enrich the functionality of the intelligent pillow, a heat therapy function is also set in this embodiment, that is, heating is carried out through the heating plate. The temperature generated by the heating plate can be conducted to the user through the pillow core and the elastic pillowcase to perform heat therapy on the head and neck. The heating plate is divided into multiple independently heated areas, such as multiple groups of independently controlled heating wires or other heating elements. By setting a fixed time and temperature, or manually adjusting the temperature, a heat therapy effect that meets the user can be obtained.

[0027] A matrix - type temperature - measuring area 211 is provided inside the pillow core 2. A number of flexible NTC thermistors 213 are arranged in the temperature - measuring area 211. The flexible NTC thermistors 213 are electrically connected to the control main board 8. The flexible NTC thermistors 213 are connected in a serpentine conductive - line connection manner. Sensor mounting grooves 212 for mounting the flexible NTC thermistors 213 are arranged in a matrix layout in the temperature - measuring area 211. The surface of the sensor mounting groove 212 is flush with the detection surface of the flexible NTC thermistor 213. In this embodiment, a detection circuit is also provided. By arranging flexible NTC thermistors in the matrix - type temperature - measuring area, the body surface temperature of the user can be detected. The detected data can be stored in the control main board or read and saved by an external device through a data - transmission module, detecting the change of the user's body surface temperature during sleep, which is convenient for monitoring the user's health condition. Continuous monitoring can obtain a complete body - temperature database. Due to the matrix - type layout structure, the temperature can be collected at different contact positions of the user, such as the head temperature and the neck temperature, which is convenient for zone - temperature control. It should be noted that the heating plate is provided with corresponding heating areas for different horizontal arrays of flexible NTC thermistors, that is, multiple groups of heating areas are arranged in the heating plate, and each heating area can be controlled independently. When in use, the intelligent mode can be directly used. According to the temperatures collected in different areas, the heating temperature is automatically set, so as to bring an accurate intelligent heat - therapy effect to the user. Taking this embodiment as an example, a total of four rows and eight columns of flexible NTC thermistors are arranged, that is, a total of four groups of heating areas are provided. The edge position is the neck - heating area, and one group of heating areas can be used for heating, while the other three groups heat the head. When the user moves closer to the center position, the two edge groups heat the neck correspondingly, and the other two groups heat the head. This method can be carried out in the intelligent mode. The sensing unit automatically senses the temperature and performs specific control according to the different temperatures, realizing intelligent heating control.

[0028] More specifically, the pillow core 2 includes an upper pillow core 21 and a lower pillow core 22. Matching slots 221 that match the lifting mechanism 3 are provided inside both the upper pillow core 21 and the lower pillow core 22. The surface layer of the upper pillow core 21 is a temperature-adjusting buffer layer 214, and wax-based composite phase change microcapsules 215 are evenly filled into the temperature-adjusting buffer layer 214. The main bodies of the upper pillow core 21 and the lower pillow core 22 are made of high-elastic memory foam. In this embodiment, the pillow core is also a split structure, which can effectively cooperate with the lifting mechanism to rise and fall. At the same time, the pillow core is made of high-elastic memory foam, which not only has good elasticity, but also has a good rebound effect, is not easy to deform, and has a good supporting effect on the head and neck. More importantly, a temperature-adjusting buffer layer is provided on the upper pillow core. The wax-based composite phase change material is filled into the nano-porous material and encapsulated into the phase change microcapsules, and is evenly arranged in the temperature-adjusting buffer layer, which can realize the buffering of temperature. Each gram of paraffin can absorb / release about 200 J / g of heat, significantly buffering the temperature fluctuation. That is, when the ambient temperature is higher than the wax-based composite phase change microcapsules, the wax-based composite phase change microcapsules absorb the external heat to achieve cooling, and when the ambient temperature is lower than the wax-based composite phase change microcapsules, the wax-based composite phase change microcapsules release heat to automatically heat the pillow, which can prevent the temperature difference between the surface layer of the pillow and the head or neck from being too large, being closer to the body surface temperature, and bringing a more comfortable experience to the user. Since the temperature buffering range is small, when heat therapy is required, the heating plate is started for heat therapy, and the temperature-adjusting buffer layer mainly performs an automatic temperature adjustment without control during daily use.

[0029] More specifically, a remote controller 5 is provided on one side of the lifting mechanism 3 and is electrically connected to the control main board 8. An STM32L4 microcontroller, a storage module, and a power module are provided on the control main board 8. In this embodiment, the height adjustment and intelligent temperature control of the pillow are realized through the STM32L4 microcontroller. All the temperature data collected from users are stored in the storage module. The STM32L4 microcontroller compares the collected data and performs intelligent output control. According to the real-time feedback temperature, the heating area is associated to achieve zone heating to meet the different temperature requirements of the head and neck and provide a more comfortable experience.

[0030] More specifically, the lifting mechanism 3 includes a support top plate 31 and a bottom plate 32. A first lifting table mechanism 6 and a second lifting table mechanism 7 are provided on the bottom plate 32 and are connected to the support top plate 31. The first lifting table mechanism 6 and the second lifting table mechanism 7 have the same structure. The lifting mechanism is a split structure, and two lifting tables are provided inside. The two lifting tables are symmetrically arranged to support the support top plate and perform lifting control, and the lifting speed is the same.

[0031] More specifically, the first lifting table mechanism 6 includes a lifting top plate 61, a lifting bottom plate 62, a folding lifting bracket 63, and a lifting motor 64. The folding lifting bracket 63 and the lifting motor 64 are arranged on the lifting bottom plate 62, and the lifting motor 64 is drivingly connected to the folding lifting bracket 63. The top of the folding lifting bracket 63 is connected to the lifting top plate 61. In this embodiment, the folding lifting bracket is driven and controlled by the lifting motor to adjust the height of the pillow. The lifting motor is a servo motor, and the adjustment and control of the lifting are more precise.

[0032] More specifically, the folding lifting bracket 63 includes four lifting support rods 631 arranged in a crosswise manner and three transverse support rods 632 arranged between the lifting support rods 631. The three transverse support rods 632 are arranged away from the lifting motor 64 and are all movably connected to the lifting support rods 631. Guide plates are arranged on both sides of the opposite surfaces of the lifting top plate 61 and the lifting bottom plate 62, and guide rail grooves 621 are arranged inside the guide plates. The guide rail grooves 621 are matched with the transverse support rods 632 and the two ends of the driven lead screw. In this embodiment, the specific lifting method of the lifting mechanism is that the driving motor drives the lifting support rods to rotate, and the transverse support rods are restricted by the guide rail grooves, so that the transverse support rods can only move in the guide rail grooves, and then drive the lifting support rods to lift, and then drive the lifting top plate to lift. The overall structure is simple, the lifting effect is good, and the adjustment of the height is more accurate under the drive of the servo motor.

[0033] More specifically, a transmission seat 65 is arranged inside the lifting support rod 631 on one side of the bottom of the folding lifting bracket 63. A driven lead screw is arranged inside the transmission seat 65, and a bearing seat 66 is arranged outside the transmission seat 65. The bearing seat 66 is connected to the lifting motor 64 to support the output shaft of the lifting motor 64. The output shaft of the lifting motor 64 is a lead screw. The part of the output shaft passing through the bearing seat 66 is a smooth surface, and the part in contact with the driven lead screw of the transmission seat 65 is a threaded surface. The end of the output shaft is also a smooth surface, and a support seat 67 with a bearing is arranged at the end. The support seat 67 is fixed on the lifting bottom plate 62. In this embodiment, the driving motor adopts lead screw transmission. A thread is arranged in the middle of the output shaft to cooperate with the driven lead screw to drive the lifting support rod to rotate and lift, and the output shaft is supported and rotated through the bearing seat and the support seat. The transmission is more stable without jitter, ensuring the smoothness of the lifting.

[0034] Working principle of the present invention: The upper pillow core 21 can adopt a wave-shaped structure that conforms to ergonomics. When the user lies on it, the neck and head present a curved posture on the pillow core. When different users use it, the required pillow height is different. In the initial state, the pillow is at the lowest height. When the height needs to be adjusted, just press the switch and select the rising function. The lifting motor 64 is a servo motor, which can accurately control the rotation speed, and thus can accurately control the lifting height. The lifting top plate 61 pushes the upper pillow core 21 to rise, so as to realize the adjustment of height. Since the overall size of the lifting top plate 61 is smaller than the size of the pillow core 2, there will be no large opening at the edge of the pillow core when rising, and it is still constrained by the elastic pillowcase 1 to ensure the use comfort. Each user can set the memory state through the remote control after the height is completed. For example, the flat lying state is memory 1, and the side lying state is memory 2. Subsequently, the most suitable height can be automatically adjusted by selecting the corresponding memory state; during the use process, the pillow also has a temperature adjustment function. First, the surface layer of the upper pillow core 21 is a temperature adjustment buffer layer 214, which adopts a structure filled with wax-based composite phase change microcapsules 215. The wax-based composite phase change material is a passive heat storage and heat release material, and its melting point is 28-32 degrees Celsius, which is the most suitable temperature for sleep. When the temperature is high, it absorbs and stores heat to achieve cooling, and when the temperature is low, it releases heat to achieve heating. When the user lies on the pillow, the temperature will be automatically adjusted. If a higher temperature is required, the heating function is turned on, and the heating duration and heating temperature are set through the remote control. The heating plate 4 starts to heat up and heats the neck and the back of the head to achieve the purpose of heat therapy, so as to obtain a better use experience.

Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
