[0002] With the rapid development of society and the economy, people's pace of life is accelerating, and work pressure is increasing. Sleep quality directly affects people's physical health and quality of life. The quality of sleep is largely determined by the pillow; finding a suitable pillow can not only improve sleep quality but also prevent cervical spine problems. Current pillow designs are diverse, including herbal pillows for health and ergonomically designed pillows. However, the height of these pillows is not adjustable. Since everyone's height and weight are different, the required pillow height varies. Even the same person needs a different pillow height depending on their sleeping position. When choosing a pillow, people need to consider whether the height is suitable for them, whether it is beneficial for protecting the cervical spine, and whether it will improve sleep quality. These types of pillows cannot solve the problem of pillow height adjustment. While there are height-adjustable pillows available, they require an air pump as a power source for adjustment. Because of the air pump, noise reduction measures are needed.

The control system is equipped with a wireless control component, and the user can set the pillow through a remote control device or mobile terminal, improving the user experience and ease of use.

[0125] Of course, there are many ways to control the height of a pillow, and there are multiple ways to solve the problems in existing technologies and achieve the corresponding results.

[0126] Example 2

[0127] Based on Example 1, such as Figure 6-11 As shown, this embodiment presents another structural form of height-adjustable pillow.

[0128] Furthermore, the headrest 1 is provided with two or more height adjustment units 5, the neck pillow 2 is provided with two or more height adjustment units 5, and the airbags 7 of adjacent height adjustment units 5 are interconnected.

[0129] The above-described embodiment provides another way of setting the height adjustment unit 5. The headrest 1 is provided with two or more height adjustment units 5, and the neck pillow 2 is provided with two or more height adjustment units 5. For ease of description of the control principle, this example uses three height adjustment units 5 each for the headrest 1 and neck pillow 2. The control principle of pillows with other numbers of height adjustment units 5 is the same. When the body is lying supine, and the head and neck press against the height adjustment units 5 in the middle of the headrest 1 and neck pillow 2, the control system opens all control valves 9, and all height adjustment units 5 simultaneously deflate until the desired height is reached. Then, the control valves 9 close. At this time, the height adjustment units 5 in the middle of the headrest 1 and neck pillow 2 are at their lowest height and have the most deflation, while the height adjustment units 5 on the left and right sides of the headrest 1 and neck pillow 2 are at their highest height and have the least deflation. When the body needs to adjust... To adjust your sleeping position, lie on your right side with your head and neck pressing against the right-side height adjustment unit 5 of the headrest 1 and neck pillow 2. The control system opens the control valves 9 of all height adjustment units 5. Due to the rebound of the elastic body, the height adjustment units 5 in the middle and left side of the headrest 1 and neck pillow 2 begin to inflate, while the height adjustment units 5 on the right side of the headrest 1 and neck pillow 2 deflate due to the pressure from the head and neck, until the desired pillow height is reached. Then, the control valves 9 close. When you need to adjust your sleeping position to the left, press your head and neck again against the middle height adjustment unit 5 of the headrest 1 and neck pillow 2. The control system opens the control valves 9 of all height adjustment units 5, and the middle and left-side height adjustment units 5 of the headrest 1 and neck pillow 2 deflate to reach the desired pillow height. Due to the rebound of the elastic body, the right-side height adjustment unit 5 of the headrest 1 and neck pillow 2 inflates. In this way, the pillow can be repeatedly inflated and deflated for repeated use. The airbags 7 of adjacent height adjustment units 5 are interconnected to prevent the height adjustment units 5 from separating when the head and neck compress the height adjustment unit 5, which would cause inaccurate pillow height detection and affect the pillow's performance.

Utilizing the heating and shrinking properties of the shape memory alloy wire 902, the control system controls the opening and closing of the control valve 9 by controlling the energization and de-energization of the shape memory alloy wire 902. When energized, the shape memory alloy wire 902 heats and shrinks, driving the valve diaphragm 907 of the control valve 9 to open the control valve 9. When de-energized, the shape memory alloy wire 902 returns to its previous state, and the control valve 9 closes.

[0142] Furthermore, the sleeping posture detection component includes the pressure sensor component 8 disposed on one side of the airbag 7.

[0143] Furthermore, the pressure sensor assembly 8 is composed of multiple pressure sensor units 801 arranged in an array.

[0144] The above-described implementation of this embodiment provides another method for detecting sleeping posture. The pressure sensor assembly 8 is used to detect the pressure data of the human shoulder on the pressure sensor assembly 8. The sleeping posture is determined by detecting the average pressure of the human shoulder on the pressure sensor assembly 8 and the number of pressure sensor units exceeding the minimum response pressure value. Since different sleeping postures require different pillow heights, the detection of the human sleeping posture provides a basis for adjusting the pillow height.

[0218] S40, Obtain the pillow height value, wherein the pillow height value includes the pillow height value detected by the pillow height detection component;

[0219] S50, if the pillow height value reaches or is similar to the pillow height value corresponding to the stored and marked sleeping position, the control valve 9 is closed.

[0228] Furthermore, the pillow height value corresponding to the sleeping posture that is stored and marked is the pillow height value corresponding to the sleeping posture that is stored and marked in the data storage in the preset step.

[0229] To illustrate the height adjustment method of the height-adjustable pillow in more detail, the following examples will be used as examples.

[0230] The specific steps of a height-adjustable pillow height adjustment method are as follows:

[0231] 1. Preset steps: See Figure 31The basic state before use of a height-adjustable pillow is as follows: the control valve 9 is closed, the elastic body inside the air bladder 7 is expanded, and the air bladder 7 is filled with air. At this time, the pillow height is at its maximum value. The pillow needs to be preset before use. The preset steps are: Y10, the person lies supine with their head resting in the middle of the headrest 1 and their neck resting in the middle of the neckrest 2. The pillow height value is preset to the processor 22 via a remote control device or mobile terminal; Y20, the processor 22 sends information to the controller 24, and the controller 24 sends an opening command to the control valve 9, which opens; Y30, due to the pressure from the person's head and neck, the air bladder 7 begins to deflate, the pillow height decreases, the pillow height detection component detects the pillow height value, and the processor... Y22 acquires the pillow height value; Y40, when the pillow height value is reached or close to the preset value, the controller 24 sends a closing command to the control valve 9, and the control valve 9 closes; Y50, the sleeping posture detection component detects the sleeping posture data value at this time, and the processor 22 acquires the sleeping posture data value; Y60, the data storage 23 stores the preset pillow height value, and the data storage 23 also stores the sleeping posture data value at this time, and marks it as a supine state; if the human body feels uncomfortable with the preset pillow height at this time, it can be adjusted via remote control device or mobile terminal. The processor 22 sets a new pillow height value that is most comfortable for the human body. When the human body raises their head and neck for 2-3 seconds, the controller 24 sends an instruction to the control valve 9 to open. The elastic body inside the airbag 7 expands, causing the airbag 7 to expand. The air pressure inside the airbag 7 is lower than the air pressure outside the airbag 7, and air enters the airbag 7 through the control valve 9. The pillow returns to its basic state, and the human body rests their head and neck on the pillow again. The pillow height is adjusted again until the most comfortable pillow height is reached. The sleeping posture detection component detects the sleeping posture data value at this time, and the processor 22 acquires it. The sleeping posture data value; the data storage 23 stores the preset pillow height value, and the data storage 23 also stores the sleeping posture data value at this time, and marks it as supine state; the human body lies on its side, and the pillow height is adjusted in the same way until the pillow height that is most comfortable for the human body when lying on its side is reached, the data storage 23 stores the preset pillow height value, and the data storage 23 also stores the sleeping posture data value at this time, and marks it as side-lying state; the same method is used to preset the human body lying prone and the human body head and neck leaving the pillow state, and marks and stores them.

[0232] 2. A method for adjusting the height of a height-adjustable pillow: See [link / details]. Figure 32S10: The pillow is in its basic state. The person lies down with their head resting on the headrest 1 and their neck resting on the neckrest 2. The sleeping posture detection component starts detecting the sleeping posture data value at this time, and the processor 22 acquires the sleeping posture data value. S20: If the sleeping posture data value reaches or is similar to the sleeping posture data value corresponding to supine position stored and marked in the data memory 23, the processor 22 determines that the person's sleeping posture at this time is supine. S30: The controller 24 sends an opening command to the control valve 9, and the control valve 9 opens. S40: Due to the pressure of the head and neck, the airbag 7 starts to deflate, the pillow height detection component starts detecting the pillow height value at this time, and the processor 22 acquires the pillow height value. S50: When the pillow height value reaches or is similar to the pillow height value corresponding to supine position stored and marked in the data memory 23, the controller 24 sends a closing command to the control valve 9, the control valve 9 closes, the airbag 7 stops deflation, and the height adjustment is completed. If the sleeping posture data value detected by the sleeping posture detection component reaches or is similar to the sleeping posture data value corresponding to the side-lying position stored and marked in the data memory 24, the processor 22 determines that the human body's sleeping posture is side-lying. The controller 24 sends an opening command to the control valve 9, the control valve 9 opens, and due to the pressure of the head and neck, the airbag 7 begins to deflate. The pillow height detection component begins to detect the pillow height value, the processor 22 obtains the pillow height value, and when the pillow height value reaches the pillow height value corresponding to the side-lying position stored and marked in the data memory 23, the controller 24 sends a closing command to the control valve 9, the control valve 9 closes, the airbag 7 stops deflation, and the height adjustment is completed. If a person changes from a supine to a side-lying position during sleep, the head and neck will naturally lift for 2-3 seconds during this process. The sleeping posture detection component detects that the head and neck are off the pillow, the control valve 9 opens, the elastic body inside the airbag 7 expands, causing the airbag 7 to expand. The air pressure inside the airbag 7 is lower than the air pressure outside the airbag 7, and air enters the airbag 7 through the control valve 9. At the same time, the 2-3 seconds that the head and neck are off the pillow is just enough time for the airbag 7 to inflate, the pillow returns to its basic state, and the control valve 9 closes.When the head and neck are resting on the pillow again, the sleeping posture detection component detects that the current sleeping posture data value reaches or is similar to the side-lying sleeping posture data value stored and marked in the data memory 23. The processor 22 determines that the human body's current sleeping posture is side-lying, and the controller 24 issues an opening command to the control valve 9. Due to the pressure of the head and neck, the airbag 7 begins to deflate, the pillow height detection component begins to detect the pillow height value, and the processor 22 acquires the pillow height value. When it reaches or is similar to the pillow height value stored and marked in the data memory 23 for side-lying, the controller 24 issues a closing command to the control valve 9, the control valve 9 closes, the airbag 7 stops deflating, and the height adjustment is completed. If, during sleep, the human body changes from side-lying to supine position, due to the side-lying position... When the pillow is higher than the required height when lying on your back, the airbag 7 does not need to be inflated. The sleeping posture detection component detects that the current sleeping posture data value reaches or is similar to the sleeping posture data value corresponding to the supine position stored and marked in the data memory 23. The processor 22 determines that the human body's sleeping posture is supine, and the controller 24 sends an opening command to the control valve 9. Due to the pressure of the head and neck, the airbag 7 begins to deflate, the pillow height detection component begins to detect the pillow height value, and the processor 22 acquires the pillow height value. When the pillow height reaches or is similar to the pillow height value corresponding to the supine position stored and marked in the data memory 23, the controller 24 sends a closing command to the control valve 9, the control valve 9 closes, the airbag 7 stops deflating, and the height adjustment is completed. The pillow height can be adjusted when the human body is lying prone using the same method.
