Description

Technical Field

[0001] This invention relates to the field of bedding technology, specifically to an adjustable pillow and a method for detecting sleeping posture. Background Technology

[0002] A pillow is a sleep aid. Generally, a pillow is considered a filling material used to enhance sleep comfort. Modern medical research shows that the human spine, viewed from the front, is a straight line, but viewed from the side, it has four physiological curves. To protect the normal physiological curvature of the neck and maintain normal physiological activity during sleep, a pillow is necessary.

[0003] The required pillow height differs when lying on your back and side. Traditional pillows, whose height cannot be adjusted, cannot meet the needs of both supine and side-lying positions during sleep, and long-term use can affect neck health.

[0004] Nowadays, people often hunch over their desks, use mobile phones, and computers, which can easily lead to degeneration, thickening, and hyperplasia of the ligaments, muscles, and fascia in the cervical spine. Prolonged contraction of the anterior muscles and excessive stretching of the posterior back muscles result in significantly reduced local blood circulation, easily forming chronic aseptic inflammatory lesions, commonly known as a "dowager's hump." The formation of a dowager's hump is closely related to prolonged head-down posture. Studies have found that for every ten degrees the head tilts forward, the tension in the back of the neck increases threefold. Therefore, avoid prolonged periods of looking down at mobile phones or placing computer screens too low; choose a pillow of appropriate height when sleeping; and move your neck frequently during work and study.

[0005] Patent application number 201420777198.X discloses a sleeping posture detection method and an adjustable-height pillow, providing a pillow that can automatically adjust its height to accommodate both supine and side-lying sleeping positions. However, this pillow inflates slowly, making it unsuitable for users who frequently change sleeping positions. Furthermore, the sleeping posture detection sensor is located on a single plane, resulting in inaccurate posture detection. Additionally, this pillow is unsuitable for individuals with a dowager's hump. Summary of the Invention

[0006] To address the aforementioned shortcomings, this invention presents a height-adjustable pillow.

[0007] An adjustable pillow includes a pillow body comprising an integrally formed neck pillow section, a head pillow section, and a control section. A shoulder pillow section is integrally formed at the front of the neck pillow section. A shoulder pillow sensing cavity is formed in the middle of the shoulder pillow section, and a shoulder pillow sensor is fixedly disposed within the shoulder pillow sensing cavity. A "dowager's bag" air cushion is fixedly disposed at the bottom center of the shoulder pillow sensor. A neck pillow sensing cavity is formed in the middle of the neck pillow section, and a semi-circular soft neck pillow is fixedly disposed within the neck pillow sensing cavity. A neck pillow sensor is fixedly disposed at the top of the soft neck pillow. An adjustment cavity is provided in the middle of the headrest, and an adjustment airbag is provided in the adjustment cavity. An air tank is fixedly installed inside the headrest on both sides of the adjustment cavity. The adjustment airbag and the air tank are connected by an inflation tube. An exhaust pipe is provided on both the pouch air cushion and the adjustment airbag. A control device is provided in the middle of the control unit. The control device is connected to the adjustment airbag, the pouch air cushion and the air tank through an inflation tube. A flow valve is provided on the inflation tube and the exhaust pipe. The shoulder pillow sensor, the neck pillow sensor and the flow valve are electrically connected to the control device.

[0008] Furthermore, the control device includes a control box, which contains a controller and an air pump. The controller is electrically connected to the air pump and is also electrically connected to a shoulder pillow sensor, a neck pillow sensor, and a flow valve. The air pump is connected to an adjustable airbag, a plus-size air cushion, and an air tank via an inflation pipe.

[0009] Furthermore, a battery is installed inside the control box, and the battery is electrically connected to the air pump.

[0010] A method for detecting sleeping posture with a height-adjustable pillow: When the human body is in a supine position, the neck is located between the two shoulders. The back of the neck presses on the neck pillow sensor on the top of the soft neck pillow, and the two shoulders press on the shoulder pillow sensor, forming a triangular three-point detection. At this time, the pressure applied by the two shoulders to the shoulder pillow sensor is relatively balanced. When a person is in a side-lying position, their neck is above one of their shoulders on the lower side of the body. The side of the neck presses on the neck pillow sensor on the top of the soft neck pillow, and the lower shoulder presses on the shoulder pillow sensor, forming two detection points in front and behind. At this time, the pressure applied to both points is relatively strong.

[0011] In summary, the present invention has the following beneficial effects: This invention provides accurate detection and judgment of supine or lateral sleeping positions. By inflating or deflating the adjustable airbag, its height can be adjusted, improving the user's sleeping comfort. The air pump and air tank simultaneously inflate the adjustable airbag, allowing it to be quickly adjusted to the specified height. A pressure sensor on the shoulder pillow compresses the humerus; the pressure signal received by the shoulder pillow sensor is transmitted to the controller. The controller then controls the air pump and the flow valve on the inflation tube between the air pump and the humerus air cushion to open. The air pump inflates the humerus air cushion to the specified height, supporting and compressing the humerus to gradually eliminate pressure. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] The following is in conjunction with the appendix Figure 1-3 The present invention will be further described as follows: An adjustable pillow includes a pillow body 1, which comprises an integrally formed neck pillow portion 2, a head pillow portion 3, and a control portion 4. A shoulder pillow portion 5 is integrally formed at the front of the neck pillow portion 2. A shoulder pillow sensing cavity 51 is formed in the middle of the shoulder pillow portion 5, and a shoulder pillow sensor 52 is fixedly disposed within the shoulder pillow sensing cavity 51. A "dowager's bag" air cushion 53 is fixedly disposed at the bottom center of the shoulder pillow sensor 52. A neck pillow sensing cavity 21 is formed in the middle of the neck pillow portion 2, and a semi-circular soft neck pillow 22 is fixedly disposed within the neck pillow sensing cavity 21. A neck pillow sensor 23 is fixedly disposed at the top of the soft neck pillow 22. The head pillow... An adjustment chamber 31 is provided in the middle of part 3. An adjustment airbag 32 is provided in the adjustment chamber 31. An air tank 6 is fixedly provided inside the headrest part 3 on both sides of the adjustment chamber 31. The adjustment airbag 32 and the air tank 6 are connected by an inflation pipe 7. An exhaust pipe 8 is provided on both the plus-size air cushion 53 and the adjustment airbag 32. A control device is provided in the middle of the control part 4. The control device is connected to the adjustment airbag 32, the plus-size air cushion 53 and the air tank 6 through the inflation pipe 7. A flow valve 9 is provided on the inflation pipe 7 and the exhaust pipe 8. The shoulder pillow sensor 52, the neck pillow sensor 23 and the flow valve 9 are electrically connected to the control device.

[0016] The control device includes a control box 41, which contains a controller 42 and an air pump 43. The controller 42 is electrically connected to the air pump 43 and is also electrically connected to the shoulder pillow sensor 52, the neck pillow sensor 23, and the flow valve 9. The air pump 43 is connected to the regulating airbag 32, the dowager's bag air cushion 53, and the air tank 6 through the inflation pipe 7.

[0017] The control box 41 contains a battery 44, which is electrically connected to the air pump 43.

[0018] In this embodiment, the semi-circular soft neck pillow 22 provides basic support for the neck. The shoulder pillow sensor 52 receives pressure applied by the shoulders, and the neck pillow sensor 23 receives pressure applied by the neck. The shoulder pillow sensor 52 and neck pillow sensor 23 transmit the received pressure signals to the controller 42, which detects whether the person is lying supine or on their side. Based on the supine or side-lying posture, the controller 42 controls the flow valve 9 on the inflation pipe 7 or the deflation pipe 8 to open, adjusting the regulating airbag 32 to a preset height by inflating or deflating it. In this embodiment, the regulating airbag 32 is lower when lying supine and higher when lying on its side. When changing from a side-lying to a supine posture, the controller 42 controls the flow valve 9 on the deflation pipe 8 of the regulating airbag 32 to open and release a specified flow of gas, adjusting the regulating airbag 32 to the specified height. When changing from a supine to a lateral position, the controller 42 controls the air pump 43 and the flow valve 9 on the inflation pipe 7 between the air pump 43 and the adjusting airbag 32 to open, and also controls the flow valve 9 on the inflation pipe 7 between the air tank 6 and the adjusting airbag 32 to open. The air pump 43 and the air tank 6 simultaneously inflate the adjusting airbag 32, quickly adjusting it to the specified height. The flow valve 9 on the inflation pipe 7 between the air pump 43 and the air tank 6 opens, allowing the air pump 43 to replenish the air tank 6 with gas. Preferably, the flow valve 9 is used to control the air flow rate.

[0019] When a user with a dowager's hump uses an adjustable pillow in a supine position, the dowager's hump compresses the shoulder pillow sensor 52. The pressure signal received by the shoulder pillow sensor 52 is transmitted to the controller 42. The controller 42 controls the air pump 43 and the flow valve 9 on the air pipe 7 between the air pump 43 and the dowager's hump air cushion 53 to open. The air pump 43 inflates the dowager's hump air cushion 53 to the specified height, supporting and compressing the dowager's hump to gradually eliminate it.

[0020] A method for detecting sleeping posture with a height-adjustable pillow: When the human body is in a supine position, the neck is located between the two shoulders. The back of the neck presses on the neck pillow sensor 23 on the top of the soft neck pillow 22, and the two shoulders press on the shoulder pillow sensor 52, forming a triangular three-point detection. At this time, the pressure applied by the two shoulders to the shoulder pillow sensor 52 is relatively balanced.

[0021] like Figure 4 As shown, the neck pillow sensor 23 receives the pressure of the human neck, and the shoulder pillow sensor 52 receives the pressure of the human two shoulders. The pressure applied by the two shoulders to the shoulder pillow sensor 52 is relatively balanced. The three pressures form a triangle for three-point detection, which determines that the human body is in a supine position.

[0022] When the human body is in a side-lying position, the neck is above one of the shoulders on the lower side of the body. The side of the neck presses on the neck pillow sensor 23 on the top of the soft neck pillow 22, and the shoulder on the lower side of the body presses on the shoulder pillow sensor 52, forming two-point detection at the front and back. At this time, the pressure applied to these two points is relatively strong.

[0023] like Figure 5 As shown, the neck pillow sensor 23 receives the pressure of the human neck, and the shoulder pillow sensor 52 receives the pressure of the lower shoulder, forming two detection points in front and behind. At this time, the pressure applied to these two points is relatively strong, indicating that the human body is in a side-lying position.

[0024] In summary, this invention is not limited to the specific embodiments described above.
