Pillow has become an indispensable articles of daily use now, and a suitable pillow is crucial to people's sleep quality. When people choose the pillow, different requirements are also provided for the height of the pillow besides different requirements for the hardness degree. The height of the pillow can also have great influence on the sleeping quality of people, and the requirements of different sleeping postures on the height of the pillow are different. Usually the optimum pillow height for side lying is higher than the optimum pillow height for supine lying. The heights of the pillows on the market are basically fixed and do not have the function of height adjustment, so that the sleeping requirements of people cannot be met. The prior pillow with adjustable height is generally internally provided with one or more air inflation chambers, and a user can perform multiple air inflation and deflation tests by using a manual or electric air pump to adjust the pillow to a proper height according to the requirement of individuals on the height of the pillow before sleeping. The inflatable pillow has complicated height adjusting process and can not meet different requirements on the height of the pillow when a user adjusts different sleeping postures in sleeping.

The embodiment of the disclosure provides a pillow, which can be adjusted to different heights, has simple and efficient adjusting process, and is suitable for different requirements of users on the height of the pillow in different sleeping postures, so that the problem that the existing inflatable pillow is complex in adjusting height process and cannot meet different requirements of users on the height of the pillow when the users adjust different sleeping postures in sleeping is solved.

Referring to fig. 1-5, embodiments of the present disclosure provide a pillow 100 including a pillow cover 200, an airbag 300, a support structure 400, a height adjustment device, and a control device. The pillow cover 200 defines an accommodation space therein. The airbag 300 is disposed in the accommodating space, and the airbag 300 can be inflated or deflated. The support structure 400 is disposed in the accommodating space, and the support structure 400 configures the mounting space. The height adjusting device is disposed in the installation space, and is connected to the air bag 300 for inflating or deflating the air bag 300 to adjust the height of the pillow 100. The control device is disposed in the installation space, and is electrically connected with the height-adjusting device, and is used for controlling the height-adjusting device to inflate or deflate the airbag 300 so as to adjust the height of the pillow 100.

By adopting the pillow 100 provided by the embodiment of the disclosure, different heights can be adjusted in the use process, the adjustment process is simple and efficient, and different requirements of users on the heights of the pillow 100 in different sleeping positions are met.

For ease of understanding, the user takes a supine sleeping position with pillow 100 positioned horizontally for use as shown in fig. 4. Along the width direction of the pillow 100, the part of the pillow 100 close to the cervical vertebra of the user is taken as the front part of the pillow 100, the part for supporting the head of the user is taken as the middle part of the pillow 100, and the part far away from the head of the user is taken as the rear part of the pillow 100. Wherein the height of the pillow 100 refers to the distance between the lowest point of the head and the plane where the pillow 100 is placed (bottom wall of the pillow 100), as shown by h1 in fig. 4 and h2 in fig. 5.

The pillow 100 provided by the embodiments of the present disclosure includes a pillow cover 200, an airbag 300, a support structure 400, a height adjusting device, and a control device. The pillow cover 200 defines an accommodating space therein, and the airbag 300 and the support structure 400 are disposed in the accommodating space. The airbag 300 is located in the middle of the pillow 100. The support structure 400 is positioned at the rear of the pillow 100 to construct a stable installation space in which the height adjusting device and the control device are installed. Wherein the balloon 300 can be inflated or deflated to change its volume. The control device can automatically control the height adjusting device to inflate or deflate the air bag 300 under a certain condition so as to change the volume of the air bag 300 and further adjust the height of the pillow 100, thereby meeting the requirements of users on different heights of the pillow 100 in different sleeping postures and providing better use experience for the users.

Illustratively, the pillow cover 200 may be made of cotton, hemp, or the like. The fabric can be used by directly contacting skin, has good air permeability and hygroscopicity, and can enable the use experience of users to be better. The airbag 300 is made of a material having good ductility, so that the service life of the pillow 100 can be prolonged.

Specifically, the support structure 400 may be made of a polymer material having a certain hardness and high elasticity, which is harmless to the human body. The support structure 400 may be in the shape of a transverse groove or a closed rectangle. The specific shape of the support structure 400 is not limited and may be set by a user according to specific needs. Further, the height adjusting device and the control device comprise a part with harder material, and the height adjusting device and the control device are arranged in the installation space of the support structure 400, so that a user can be effectively prevented from directly contacting a hard object, and the user is prevented from being injured. Moreover, this also makes the height adjusting device and the control device less vulnerable.

Specifically, the number of the air bags 300 may be one or more. Taking the example that the number of the air bags 300 is two, one is located at the intermediate position and the other is located around the air bag 300 at the intermediate position. In this way, in the using process of the pillow 100, the air bags 300 in the middle position can be adjusted to the height of the sleeping position of the user on the back, and the heights of the air bags 300 on the two sides can be adjusted only when the user adjusts to the sleeping position on the side, so that the air inflation or deflation amount of the air bags 300 can be reduced, the speed of adjusting the height of the pillow 100 after the user changes the sleeping position is improved, and the user has better using experience.

It is understood that the bladder 300 and the support structure 400 together form the basic shape of the pillow 100. Along the width of the pillow 100, the air cells 300 are positioned at the front and middle portions of the pillow, and the portion of the air cells 300 positioned at the neck of the user can be used to support the neck of the user and the portion positioned at the head of the user can be used to support the head of the user. The support structure 400 is located at the rear of the pillow 100, away from the user's head, without causing discomfort to the user.

Optionally, the pillow 100 further comprises an elastic filler 600. In this way, the support structure 400, the air bag 300 and the elastic filler 600 are sequentially arranged along the width direction of the pillow 100 and are respectively positioned at the rear part of the pillow 100, the middle part of the pillow 100 and the front part of the pillow 100, so that the support structure 400 is far away from the head of a user, discomfort is not caused to the user, the air bag 300 can adjust the requirements of the user on different heights of the pillow 100 under different sleeping postures, and the elastic filler 600 can deform along with the height change of the pillow 100 in the sleeping posture changing process of the user so as to bring good supporting effect to the neck of the user. Optionally, the height adjustment device includes a pneumatic assembly and a drive 510. The pneumatic assembly is fixedly installed in the installation space, and the pneumatic assembly is connected to the air bag 300 for inflating or deflating the air bag 300. The driving member 510 is fixedly installed in the installation space, and the driving member 510 is connected to the pneumatic assembly for driving the pneumatic assembly to inflate or deflate the airbag 300 to adjust the height of the pillow 100.

So configured, the driving member 510 and the pneumatic assembly are fixedly installed at both sides of the installation space where the support structure 400 is constructed, respectively, through the fixing members. The pneumatic assembly is connected to the air bag 300, and the air bag 300 can be inflated or deflated under the driving of the driving member 510, thereby adjusting the height of the pillow 100. By the cooperation of the driver 510 and the pneumatic assembly, the airbag 300 can be inflated or deflated efficiently.

Specifically, the driver 510 may employ a motor for driving the pneumatic assembly to inflate or deflate the balloon 300. The motor may be a stepping motor or a servo motor, so that the number of turns of the motor can be precisely controlled, thereby achieving precise control of the inflation amount of the airbag 300.

Optionally, the pneumatic assembly includes a cylinder 533, a piston 532, and a top post 531. The air cylinder 533 is fixedly installed in the installation space, and the air cylinder 533 communicates with the airbag 300. A piston 532 is provided in the cylinder 533, and the piston 532 is reciprocable in the cylinder 533. The top post 531 has one end connected to the piston 532 and the other end connected to the driving member 510, and the driving member 510 drives the top post 531 to drive the piston 532 to reciprocate in the cylinder 533 so as to inflate or deflate the airbag 300.

As shown in connection with fig. 3, the pneumatic assembly includes a cylinder 533, a piston 532, and a top post 531. Wherein, the cylinder 533 is fixedly installed at one side of the installation space, and the piston 532 is disposed in the cylinder 533 and can reciprocate in the cylinder 533. One end of the top column 531 is connected to the piston 532, and the other end is connected to the driving member 510, so that the driving member 510 can drive the top column 531 to drive the piston 532 to reciprocate in the cylinder 533, so as to inflate or deflate the airbag 300. In addition, the driving piece 510 is fixedly installed on the other side of the installation space, a certain distance exists between the driving piece 510 and the air cylinder 533, and thus the range of the air charging amount of the air bag 300 can be set by reasonably setting the size of the air cylinder 533 and the length of the top column 531, so that the height adjustable range of the pillow 100 is controlled, and further the use requirements of users on different heights of the pillow 100 are met.

Further, the air bag 300 is inflated or deflated by the reciprocating movement of the piston 532 in the air cylinder 533, so that the noise in the adjusting process can be smaller and the user experience is better in the mode of adjusting the height of the pillow 100. Movement of the piston 532 away from the driver 510 inflates the bladder 300 and movement of the piston 532 toward the driver 510 deflates the bladder 300.

Optionally, the height adjusting device further comprises a transmission assembly. The transmission assembly is fixedly installed in the installation space, one end of the transmission assembly is connected to the driving member 510, the other end of the transmission assembly is connected to the pneumatic assembly, and the driving member 510 drives the transmission assembly to drive the pneumatic assembly to inflate or deflate the airbag 300 so as to adjust the height of the pillow 100.

So set up, drive assembly passes through mounting fixed mounting in installation space, makes drive assembly's one end (transmission input) connect in drive piece 510, and the other end (transmission output) connect in pneumatic assembly, and drive piece 510 can drive assembly like this and drive pneumatic assembly and aerify or deflate in order to adjust the height of pillow 100 to gasbag 300. In this way, the driving member 510, the transmission assembly and the pneumatic assembly cooperate to inflate or deflate the air bag 300 more stably, efficiently and precisely.

Optionally, the transmission assembly includes a worm gear structure, a screw, and a connecting rod. The worm and gear structure comprises a worm and a worm wheel which are in transmission connection, and the worm is connected with the driving piece. The screw is rotatably disposed in the installation space along the length direction of the pillow 100, and is fixedly inserted into the worm gear of the worm gear structure, and the screw can rotate along with the worm gear. The first end of connecting rod wears to locate the screw rod, and second end fixed connection is in the jack-prop. When the screw rod rotates, the first end of the connecting rod can move in the axial direction of the screw rod, so that the jack post is driven to move.

As shown in fig. 2 and 3, the screw 523 is rotatably installed in the installation space along the length direction of the pillow 100. Both ends of the screw 523 are fixedly installed in the installation space through the supporting members 522, the screw 523 is slidably connected with the supporting members 522, one end of the screw 523 is fixed near the driving member 510, and the other end is fixed near the air cylinder 533. In the drive connection worm 521 and worm wheel 524, the worm 521 is connected to the drive 510. The screw 523 is fixed to a worm gear 524 penetrating through the worm gear structure, and the screw 523 can be rotated by the worm gear 524. The first end of the connecting rod 525 is inserted into the screw 523, the second end of the connecting rod 525 is fixedly connected to the top column 531, and when the screw 523 rotates, the first end of the connecting rod 525 can move in the axial direction of the screw 523, so as to drive the top column 531 to move. Thus, the worm wheel 524 rotates to move the connecting rod 525 in the axial direction of the screw 523 to enable the top column 531 to drive the piston 532 to reciprocate in the cylinder 533 to charge or discharge the air bag 300, so as to adjust the height of the pillow 100.

Further, by adopting the mode of meshing the worm wheel 524 with the worm 521 in the worm wheel and worm structure, the driving piece 510 can be rotated to drive the worm 521 to rotate for deceleration treatment, so that the worm wheel 524 can drive the screw 523 to rotate slowly, and the piston 532 can slowly reciprocate in the cylinder 533 at a uniform speed, so that the airbag 300 can deform in the slow inflation or deflation process, the height adjustment process of the pillow 100 is not easy to perceive, and better use experience is provided for users. And worm wheel 524 engages worm 521 to inflate or deflate balloon 300 only when driver 510 is actively rotating. Due to the meshing of worm wheel 524 and worm 521, direct compression of air bag 300 does not reverse worm wheel 524, thereby preventing slow deflation of air bag 300 during compression.

Specifically, a threaded hole is provided at one end of the connecting rod 525 penetrating the screw 523. The worm wheel 524 rotates to drive the screw 523 to rotate, and the interaction of the screw 523 and the threaded hole enables the connecting rod 525 to move between two ends of the screw 523, so that the connecting rod 525 drives the jacking column 531 to enable the piston 532 to reciprocate in the air cylinder 533 to inflate or deflate the air bag 300. The screw 523 may be disposed parallel to the top post 531, so that the resistance of the connecting rod 525 moving on the screw 523 to drive the top post 531 to move is smaller, and the movement is smoother.

Optionally, the link 525 is provided with a pulley 5251, the pulley 5251 being in sliding contact with the support structure 400.

So set up, press close to the both sides of bearing structure 400 at connecting rod 525 and set up pulley 5251 respectively, and make pulley 5251 and corresponding bearing structure 400 sliding contact, pulley 5251 can provide certain supporting role like this between bearing structure 400, and then make the removal of connecting rod 525 on screw 523 more smooth and stable.

Specifically, the connecting rods 525 extend out of the protrusions proximate to both sides of the support structure 400, and the pulleys 5251 are mounted at the ends of the protrusions so that the pulleys 5251 can slide along the inner wall of the support structure 400.

Optionally, pillow 100 further comprises an airway 540. The air duct 540 has one end connected to the airbag 300 and the other end connected to the cylinder 533.

So set up, with gasbag 300 and cylinder 533 through air duct 540 connection, can make things convenient for the cylinder 533 to aerify or the gassing to gasbag 300 in order to adjust the height of pillow 100 more.

Specifically, the end of the cylinder 533 is provided with a vent hole, and one end of the air duct 540 is connected to the vent hole, and the other end is connected to the airbag 300, thereby inflating or deflating the airbag 300. Further, in order to prevent the air bladder 300 from leaking air to change the height of the pillow 100 due to the slow release of air from the air cylinder 533, an electromagnetic valve may be installed in the air duct 540. The solenoid valve is electrically connected to the driving member 510, and is opened to inflate or deflate the airbag 300 only when the driving member 510 is actively rotated. The solenoid valves for pressing the air bag 300 or the air cylinder 533 to slowly release air are in a closed state, so that the air bag 300 cannot discharge air, and thus the height of the pillow 100 cannot be changed.

In another embodiment, solenoid valves in the air cylinder 533 and air duct 540, and in the air duct 540, may be eliminated. The airbag 300 is made to be more irregularly shaped, wherein a part of the airbag protrudes and extends to the position of the air cylinder 533, and when the pillow 100 is controlled to be lifted or lowered, the piston 532 directly presses or is far away from the airbag extension part at the air cylinder 533. Thus, the structure can be simplified, and the possibility of air leakage is avoided.

Optionally, the pillow 100 further comprises an elastic filler 600. The elastic filler 600 is disposed in the receiving space, and the support structure 400, the airbag 300, and the elastic filler 600 are sequentially arranged in the width direction of the pillow 100.

In this way, the elastic filler 600 is provided at the front of the pillow 100, so that the neck of the user can be effectively supported, and the user experience is better. In this way, the support structure 400, the air bag 300 and the elastic filler 600 are sequentially arranged along the width direction of the pillow 100 and are respectively positioned at the rear part of the pillow 100, the middle part of the pillow 100 and the front part of the pillow 100, so that the support structure 400 is far away from the head of a user, discomfort is not caused to the user, the air bag 300 can adjust the requirements of the user on different heights of the pillow 100 under different sleeping postures, and the elastic filler 600 can deform along with the height change of the pillow 100 in the sleeping posture changing process of the user so as to bring good supporting effect to the neck of the user.

Specifically, the clockwise rotation of the driving member 510 is a forward rotation, and the counterclockwise rotation is a reverse rotation. When the height of the pillow 100 needs to be increased, the driving member 510 rotates clockwise to rotate the worm 521, and the worm 521 engages with the worm wheel 524 to reduce the rotation speed. The worm wheel 524 rotates to drive the screw 523 to rotate, and the screw 523 can only rotate and cannot move in the axial direction due to the action of the support 522. Screw 523 interacts with a threaded bore in rod 525 to move rod 525 from a side near driver 510 to a side of cylinder 533 on screw 523. The connecting rod 525 drives the top column 531 to enable the piston 532 to move in the cylinder 533 from the side close to the driving piece 510 to the side far away from the driving piece 510, so that the air in the cylinder 533 is extruded by the piston 532 to enter the air bag 300 from the air duct 540, and the air bag 300 is inflated to raise the height of the pillow 100. When the height of the pillow 100 needs to be lowered, the driving member 510 rotates counterclockwise, the whole process is reversed, the gas in the air bag 300 enters the cylinder 533, and the air bag 300 is exhausted to lower the height of the pillow 100.

Optionally, the control device includes a main control module 710 and a sensing device 720. The main control module 710 is fixedly arranged in the installation space, and the main control module 710 is electrically connected with the height adjusting device. The sensing device 720 is disposed on the surface of the airbag 300, and the sensing device 720 is used for detecting and collecting the compressed data of the airbag 300 and transmitting the compressed data to the main control module 710. The sensing device 720 is electrically connected with the main control module 710, and the main control module 710 controls the height adjusting device to inflate or deflate the airbag 300 according to the compressed data so as to adjust the height of the pillow 100.

By arranging the sensing device 720 on the surface of the air bag 300, the pressed data of the air bag 300 can be detected and collected at any time, and the pressed data can be transmitted to the main control module 710 in time. The main control module 710 is fixedly arranged in the installation space, so that the main control module 710 is not extruded and is prevented from being damaged. Because the main control module 710 is electrically connected with the height-adjusting device, the main control module 710 can control the height-adjusting device to inflate or deflate the airbag 300 according to the compressed data so as to adjust the height of the pillow 100, thereby meeting the different requirements of users on the height of the pillow 100 in different sleeping positions.

Specifically, sensing device 720 includes a plurality of pressure sensors. The plurality of pressure sensors may be made of a piezoelectric ceramic material. The pressure sensors can be uniformly distributed on the surface of the air bag 300, and the pressure data on the surface of the air bag 300 can be detected and collected at any time. Thus, when the user changes the sleeping posture, the compression data on the surface of part of the air bags 300 will be changed, at this time, the pressure sensor transmits the collected compression data to the main control module 710, and the main control module 710 controls the height adjusting device to timely inflate or deflate the air bags 300 according to the compression data so as to adjust the height of the pillow 100.

Specifically, taking the example of the user sleeping with his head in the middle of the pillow 100. When the user adjusts from the supine sleeping position to the lateral sleeping position, the pressure sensor on the surface of the air bag 300 located at the lateral part detects that the pressure is increased, at this time, the pressure sensor transmits the collected pressure data to the main control module 710, and the main control module 710 controls the height adjusting device to timely inflate the air bag 300 according to the pressure data so as to increase the height of the pillow 100. When the user adjusts from the side sleeping position to the supine sleeping position, the pressure sensor on the surface of the air bag 300 at the side part detects that the pressure becomes smaller, and the pressure sensor on the middle part detects that the pressure becomes larger, at this time, the pressure sensor transmits the collected compressed data to the main control module 710, and the main control module 710 controls the height adjusting device to timely deflate the air bag 300 according to the compressed data so as to reduce the height of the pillow 100.

Further, the head is in a side position of the pillow 100 when the user falls asleep. It will be appreciated that the contact area of the user with the pillow 100 is greater in the supine position than in the lateral position, i.e., the supine position contacts more pressure sensors on the surface of the bladder 300. Therefore, when the user adjusts from the supine sleeping position to the side sleeping position, the pressure sensor on the surface of the air bag 300 detects that the pressure contact area is reduced, and at this time, the pressure sensor transmits the collected compressed data to the main control module 710, and the main control module 710 controls the height adjusting device to timely inflate the air bag 300 according to the compressed data so as to increase the height of the pillow 100.

Alternatively, the main control module 710 may be communicatively connected with an external smart terminal.

So set up, the main control module 710 can be connected with external intelligent terminal communication, can make the user use more convenient, intelligent to pillow 100 like this.

Specifically, the external intelligent terminal comprises a mobile phone, a tablet personal computer and other devices, and the external intelligent terminal can monitor sleep data of a user in real time through the APP. The communication connection mode comprises WIFI communication and Bluetooth communication. Thus, the user can monitor the sleep data of the user in real time through the mobile phone, and parameters such as frequency, range and the like of the pillow 100 which the user is used to can be set up in the control module of the pillow 100.

In some embodiments, taking the pillow 100 provided by embodiments of the present disclosure as an example, a user uses the pillow for the first time. Referring to fig. 4 and 5, for example, the height value of the user-supine sleeping posture air bag 300 may be set to h1, and the height value of the user-lateral sleeping posture air bag 300 may be set to h2. Typically, the user will fall asleep in a supine position, the height of the user's supine position air bag 300 can be set to the initial default height of the pillow 100, such that the sensing device 720 will undergo a pressure change when the user is in a side-lying position. The main control module 710 controls the height adjusting device according to the compressed data sent by the sensing device 720 to make the driving member 510 rotate forward to inflate the airbag 300 in time, so as to adjust the height of the pillow 100 to meet the requirement of the user on the height of the pillow 100. In contrast, when the user changes from the side sleeping position to the supine sleeping position, the main control module 710 controls the height adjusting device according to the pressed data sent by the sensing device 720, so that the driving member 510 rotates reversely to timely deflate the air bag 300, and the height of the pillow 100 is adjusted to meet the requirement of the user on the height of the pillow 100.

The driving member 510 can be a stepping motor or a servo motor, and can precisely control the number of turns, the number of turns being operated when the pillow is inflated, and the number of turns being reversed when the pillow is deflated, so that the height of the pillow 100 can be regulated more stably and precisely. The driver 510 is subjected to a resistive force during operation, which is related to the pressure of the balloon 300, the greater the resistive force. The operating voltage is constant for the driver 510, with the greater the resistance, the greater the current. It is possible to determine whether the airbag 300 reaches a preset height value by monitoring the operation current of the motor.

Optionally, the inflation starts to reach the first preset height value, and the running current reaches the first value, that is, the current number required when the motor overcomes the pressure of the air bag 300 in the supine state and reaches the first preset height value. And (3) starting to inflate until reaching a second preset height value, and ending the operation current reaching a second value, namely the current number required by the motor when overcoming the pressure of the air bag 300 in the lateral lying state and reaching the second preset height value. Taking the sleeping position of the user in the supine position as an example, the first preset height value is the initial air bag height when the user sleeps. And when the motor is inflated again in the use process, the motor current reaches a second value, and the motor can be stopped. When the air is discharged, the current reaches a first value, and the air can be stopped.

Illustratively, taking the height value h1 of the user's supine sleeping position air bag as a first preset height value, the height value h2 of the user's lateral sleeping position air bag as a second preset height value, and taking the user's supine sleeping position as an example. When the user falls asleep, the display value of the running current is 0.1A, and the first value is 0.1A. When the user adjusts from the supine sleeping position to the side sleeping position, the air bag 300 starts to be inflated to reach the second preset height value, the running current needs to be increased by 0.1A, and the user can stop until reaching 0.2A, and the second value is 0.2A. When the user adjusts from the side-lying sleeping position to the supine sleeping position, the air bag 300 starts to deflate to the first preset height value, and the operation current needs to be reduced by 0.1A, and the operation current can be stopped to reach 0.1A.
