An angle adjusting mechanism for adjusting the inclination angle of the second support layer 3 is arranged in the base layer. The side wing plate 20 is arranged above the pillow body, and is located at the left end and / or the right end above the second support layer 3. Specifically, the first support layer 2 is a neck support area of the pillow, which supports the neck of the patient, the middle part of the neck support area and the third support layer 4 can be provided with a shoulder avoiding recess which is recessed from the front end of the pillow body to the back, so as to avoid the pressure on the shoulder when lying on the side; the second support layer 3 is a head support area which supports the head and neck of the patient, and the head support area can be provided with a head recessed area which is recessed from the top of the pillow body to the bottom, and the recessed area is provided with a head-shaped curved surface to improve the comfort of the patient when using; the materials of the first support layer 2, the second support layer 3 and the third support layer 4 are all memory foam.

[0022] The base layer comprises a hard bottom plate 6, a flexible covering layer 5 and a third support layer 4, the flexible covering layer 5 is fixed above the hard bottom plate 6, the top surface of the flexible covering layer 5 is connected with the bottom surface of the second support layer 3, an adjusting cavity 7 is formed between the flexible covering layer 5 and the hard bottom plate 6, the angle adjusting mechanism is located in the adjusting cavity 7, and the third support layer 4 is located below the first support layer 2, and the bottom surface of the third support layer 4 is located on the same horizontal plane as the bottom surface of the hard bottom plate 6. The hard bottom plate 6 provides a support base for the arrangement of the angle adjusting mechanism, the flexible covering layer 5 can be made of cloth, the flexible covering layer 5 can be expanded or contracted by the driving of the angle adjusting mechanism, the flexible covering layer 5 has a certain covering and protection effect on the angle adjusting mechanism, and also has a separation effect on the angle adjusting mechanism and the second support layer 3.

[0023] More specifically, the angle adjusting mechanism comprises a cylindrical track 8, a support plate 9, an extendable air bag 18, a sliding plate 16 and a support air bag. The cylindrical track 8 is fixedly connected to the top surface of the hard bottom plate 6, and the length direction of the cylindrical track 8 is arranged along the front-rear direction of the pillow. The support plate 9 is located above the cylindrical track 8, and one end of the support plate 9 is rotatably connected to one end of the cylindrical track 8 close to the first support layer 2. The top surface of the support plate 9 is connected to the flexible covering layer 5. The extendable air bag 18 and the sliding plate 16 are arranged in the cylindrical track 8. One end of the extendable air bag 18 away from the first support layer 2 is fixedly connected to the cylindrical track 8, and the other end of the extendable air bag 18 is fixedly connected to the sliding plate 16. The sliding plate 16 is elastically connected to the cylindrical track 8 through a spring 17. The extension direction of the spring 17 is consistent with the length direction of the cylindrical track 8. A sliding groove is formed in the top of the cylindrical track 8 along the length direction. The top of the sliding plate 16 extends to the outside of the cylindrical track 8 through the sliding groove and is fixedly connected with a push block 10. The outer surface of the push block 10 is in contact with the bottom surface of the support plate 9. The support air bag is located in the adjusting cavity 7. The top surface of the support air bag is connected to the flexible covering layer 5, and the bottom surface of the support air bag is connected to the hard bottom plate 6. The support air bag and the extendable air bag 18 are respectively provided with an inflation port for inflation and a deflation port for deflation.

[0024] When the angle needs to be adjusted, the support air bag and the extendable air bag 18 are inflated through the inflation ports. When the extendable air bag 18 is inflated with gas, the extendable air bag 18 expands along the cylindrical track 8, thereby driving the sliding plate 16 to move towards the first support layer 2. The push block 10 moves with the sliding plate 16, and the spring 17 is compressed at this time. As the push block 10 approaches the connection point of the support plate 9 and the cylindrical track 8, the free end of the support plate 9 is gradually lifted and rotated around the connection point. The support plate 9 pushes the second support layer 3 to tilt, thereby achieving angle adjustment. As the second support layer 3 tilts, the space of the adjusting cavity 7 increases, and the inflation and expansion of the support air bag can fill the adjusting cavity 7, so that the pillow is in a "non-hollow" state, thereby ensuring the support effect of the pillow. Similarly, the support air bag and the extendable air bag 18 can be deflated, so that the second support layer 3 gradually lowers and returns to a planar state. After the extendable air bag 18 is deflated, the spring 17 loses pressure, and the spring 17 returns to its original state. During the recovery process of the spring 17, the sliding plate 16 is pushed to move away from the first support layer 2.

[0025] When the patient is reset, the angle adjustment range of the second support layer 3 is preferably 15°-30°.

[0026] More specifically, the push block 10 is circular in shape, the axis direction of the push block 10 is perpendicular to the length direction of the cylindrical track 8, the support plate 9 is provided with an arc convex surface 19 at the bottom of the end away from the first support layer 2, and the arc convex surface 19 is curved upward from the end close to the first support layer 2 to the end away from the first support layer 2. When the push block 10 moves to the end of the arc convex surface 19 away from the first support layer 2, the top surface of the push block 10 can be above the bottom surface of the support plate 9, so that the support plate 9 can be parallel or tend to be parallel to the cylindrical track 8, avoiding the push block 10 always being below the bottom surface of the support plate 9, and keeping the free end of the support plate 9 always in a state of being obviously lifted. The circular shape of the push block 10 and the arc convex surface 19 of the support plate 9 can improve the relative sliding effect between the push block 10 and the support plate 9, and can improve the angle adjustment effect of the support plate 9, so that the ear stone resetting pillow can be used as a regular pillow.

[0027] The angle adjustment mechanism has two, two of the angle adjustment mechanism is located in the left and right sides of the adjusting cavity 7, the support air bag is located between the two angle adjustment mechanism. Setting two angle adjustment mechanism can improve the stability of angle adjustment.

[0028] The inflation ports of the support air bag and the telescopic air bag 18 are connected with an inflation pump through the first inflation pipe 13 and the second inflation pipe 12 respectively, the first inflation pipe 13 and the second inflation pipe 12 are respectively provided with the first regulating valve 14 and the second regulating valve 15; the two exhaust ports are respectively provided with the third regulating valve and the fourth regulating valve. The inflation pump is used to inflate the support air bag and the telescopic air bag 18, the first regulating valve 14 and the second regulating valve 15 are used to adjust the air intake respectively, and the third regulating valve and the fourth regulating valve are used to adjust the air exhaust respectively. Specifically, when inflating, the flow rate of the gas passing through the second regulating valve 15 is less than that passing through the first regulating valve 14, and under the same air intake time, the air intake of the support air bag is greater than that of the telescopic air bag 18. By coordinating the air intake of the two kinds of air bags, the support plate 9 can complete the angle adjustment, and the support air bag can complete the filling of the adjusting cavity 7, without the need for the two air bags to perform inflation actions respectively. Similarly, when reducing the included angle between the second support layer 3 and the hard base, the opening degrees of the third regulating valve and the fourth regulating valve are adjusted respectively, the air exhaust of the two kinds of air bags is coordinated, and the rotation of the support plate 9 and the contraction of the support air bag can be synchronized.

[0029] More specifically, the exhaust ports corresponding to the supporting air bag and the telescopic air bag 18 are connected with exhaust pumps through the first exhaust pipe and the second exhaust pipe respectively, and the third regulating valve and the fourth regulating valve are arranged on the first exhaust pipe and the second exhaust pipe respectively to perform the exhaust action through the exhaust pumps. More specifically, the exhaust port and the inflation port are connected with pipe joints, and the pipe joints are provided with switch valves for closing and opening the pipe joints. The inflation pipe and the exhaust pipe can be connected with or separated from the pillow through the pipe joints, so that the pillow is not connected with the inflation pipe, the exhaust pipe and the air pump when the angle adjustment is not needed, and the pillow is not limited by the pipes and is free to move, thereby being conveniently moved to the required position for use.

[0030] Specifically, the side wing plate 20 is connected with the pillow through magnetic attraction, or the bottom of the side wing plate 20 is sewn and fixed on the pillow. When the magnetic attraction connection mode is adopted, the bottom of the side wing plate 20 is provided with an iron sheet, and an electromagnet is fixed on the second supporting layer 3. The electromagnet generates a magnetic force when electrified, and the iron sheet on the side wing plate 20 is adsorbed to fix the side wing plate 20 on the pillow. When the side wing plate 20 needs to be removed, the electromagnet is de-energized to lose the magnetic force, so that the side wing plate 20 can be removed and arranged. The side wing plate 20 can limit the patient's head to prevent the patient's head from deviating during use (such as when the patient is sleeping), so as to ensure that the reduction effect is not affected. When the sewing and fixing mode is adopted, the side wing plate 20 is sewn on the pillowcase 1, and the side wing plate 20 can be removed together with the pillowcase 1 for cleaning or disinfection.

[0031] More specifically, the outer surface of the side wing plate 20 near the human head is provided with flexible anti-skid convex points to improve the limiting effect of the side wing plate 20, and the anti-skid convex points are flexible to avoid pressing the patient's cheekbone and other head parts.

[0032] Specifically, the second supporting layer 3 is provided with an avoidance groove 11 above the pillow corresponding to the position. When the patient lies on one side, the patient's ear can be located in the avoidance groove 11 to reduce the pressure on the patient's ear.

[0033] Specifically, the pillowcase 1 comprises a 3D breathable mesh cloth and a phase change temperature control material layer (pcm) distributed in sequence from the outside to the inside to improve the heat dissipation effect and reduce the hot feeling of the pillow.
