[0002] With the fast pace of life and increasing work pressure, more and more people are experiencing cervical spine problems. A suitable pillow is crucial for cervical spine health, as it can provide good support for the cervical spine during sleep and relieve neck muscle fatigue.

[0003] The existing patent document CN218773686U discloses a pillow core adjustment structure for cervical spine support. The pillow core adjustment structure for cervical spine support described in this utility model is specially designed with a support adjustment component. By rotating the handle, the gas in the flexible expansion tube is compressed, changing the expansion of the flexible expansion tube, thereby changing the effective support height of the ribs for the cervical spine, making the body feel more comfortable and adapting to the different cervical spine position height of each person when sleeping.

[0004] However, the existing adjustable structures for cervical spine support pillows have a relatively simple adjustment effect. Most products can only achieve minor adjustments to the height of local areas, which is difficult to meet the diverse needs of different users for cervical spine support. Whether due to individual differences in cervical curvature or frequent changes in posture during sleep, these traditional adjustment structures cannot provide comprehensive and dynamic support. The single adjustment function not only limits the protective effect of the pillow core on the cervical spine, but also makes it difficult to continuously relieve neck fatigue during long-term use, and cannot truly meet the complex physiological needs of the human cervical spine.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a pillow core adjustment structure for cervical spine support, including a pillow core body 1, a plurality of independent flexible support sleeves 2 are arranged inside the pillow core body 1, the plurality of flexible support sleeves 2 are elongated, and an electric push rod 3 is arranged at the bottom of the pillow core body 1, the electric push rod 3 is located below the plurality of flexible support sleeves 2.

[0027] The flexible support sleeve 2 is connected to the transmission end of the electric push rod 3. Several flexible connectors 4 are set at the bottom of the flexible support sleeve 2 inside the pillow core body 1. The flexible connectors 4 and the flexible support sleeve 2 are arranged in a cross shape. An adjustment rope 5 is threaded through the flexible connector 4. One end of the adjustment rope 5 extends to the outside of the pillow core body 1 and is connected to an adjustment pull ring 6. The electric push rod 3 can precisely control the extension length and has an overload protection function. The flexible support sleeve 2 is made of a flexible material with high elasticity, wear resistance and good breathability. The flexible material is a composite material of elastic fiber and polyurethane. The flexible connectors 4 are made of flexible rubber, which has good flexibility and tensile strength, and the surface is provided with anti-slip texture. The adjustment rope 5 is a high-strength, low-elongation steel wire rope, and its outer surface is wrapped with a wear-resistant protective sleeve.

[0028] When users need to adjust the height of the pillow core, they can control the extension and retraction of the electric push rod 3 via a remote control or switch (not shown in the picture). The electric push rod 3 can precisely control the extension and retraction length and has an overload protection function. When the user needs to adjust the height of the pillow core, they activate the electric push rod 3. Since the flexible support sleeve 2 is connected to the transmission end of the electric push rod 3, the extension and retraction of the electric push rod 3 will directly drive the flexible support sleeve 2 to rise or fall. Multiple independent flexible support sleeves 2 can be adjusted to different heights under the drive of their corresponding electric push rods 3, thereby meeting the user's personalized needs for adjusting the pillow core height according to their own cervical curvature, sleeping posture, and other individual requirements. For example, when lying on their back, the height of the flexible support sleeve 2 corresponding to the cervical spine can be adjusted to a suitable height, and when lying on their side, the height of the flexible support sleeve 2 on the side can be adjusted accordingly to ensure that the cervical spine is always in a natural and comfortable physiological curve state. The overload protection function can prevent the electric push rod 3 from excessively extending or retracting due to operational errors or other reasons. Damage is prevented, ensuring the normal operation and service life of the equipment. The flexible connector 4 located at the bottom of the flexible support sleeve 2 inside the pillow core body 1, along with the adjustment rope 5 passing through it, together realize the adjustment of the pillow core shape. The flexible connector 4 is made of flexible rubber, which has good flexibility and tensile strength. The anti-slip texture on the surface ensures the stability of the adjustment rope 5 when it moves within it. When the user pulls the adjustment ring 6, the adjustment rope 5 moves within the flexible connector 4. Since the flexible connector 4 and the flexible support sleeve 2 are arranged in a cross shape, the movement of the adjustment rope 5 will change the relative position and angle between adjacent flexible support sleeves 2. For example, pulling the adjustment rope 5 makes the adjacent flexible support sleeves 2 move closer to each other, and the corresponding part of the pillow core will bulge. Releasing the adjustment rope 5 will allow the adjacent flexible support sleeves 2 to return to their relative positions, and the shape of the pillow core will change accordingly. In this way, the shape of the pillow core can be flexibly shaped according to the user's needs, better adapting to various posture changes of the human body during sleep.

[0029] An elastic support body 7 is provided inside the flexible support sleeve 2. The elastic support body 7 has a hardness adjustment cavity 8 inside. Several connecting pipes 9 are provided on one side of the pillow core body 1. The connecting pipes 9 correspond one-to-one with the flexible support sleeve 2 and are connected to the hardness adjustment cavity 8. The elastic support body 7 is made of a mixture of memory foam and elastic silicone. The hardness adjustment cavity 8 is filled with a flowable material, and the material can be injected and extracted through the connecting pipes 9. A flow control valve is provided on the connecting pipe 9 to precisely control the flow rate of the medium flowing into or out of the hardness adjustment cavity 8. The flow control valve is an electromagnetic flow control valve and can be remotely controlled by an external remote control.

[0030] The flexible support sleeve 2 has an elastic support body 7 inside which a hardness adjustment cavity 8 is provided. A connecting pipe 9 on one side of the pillow core body 1 is connected to the hardness adjustment cavity 8, and an electromagnetic flow control valve is provided on the connecting pipe 9. The elastic support body 7 is made of a mixture of memory foam and elastic silicone. The hardness adjustment cavity 8 is filled with fluid material (such as gas) and is connected to an external device (such as an air pump) through the connecting pipe 9. When the user needs to adjust the hardness of the pillow core, the electromagnetic flow control valve can be remotely controlled by an external remote control. After the valve is opened, the external device injects fluid into the hardness adjustment cavity 8 through the connecting pipe 9. As the fluid in the cavity increases, the hardness of the elastic support body 7 will increase accordingly. Conversely, if the material in the hardness adjustment cavity 8 is removed, the hardness of the elastic support body 7 will decrease. This method of precisely controlling the flow rate of the medium flowing into or out of the hardness adjustment cavity 8 can meet the user's personalized needs for the hardness of the pillow core, further improving the comfort of sleep and the protection of the cervical spine.

[0031] Working principle: When the user needs to adjust the height of the pillow core, the user can control the extension and retraction of the electric push rod 3 via a remote control or switch (not shown in the figure). The electric push rod 3 can precisely control the extension and retraction length and has an overload protection function. When the user needs to adjust the height of the pillow core, the electric push rod 3 is activated. Since the flexible support sleeve 2 is connected to the transmission end of the electric push rod 3, the extension and retraction of the electric push rod 3 will directly drive the flexible support sleeve 2 to rise or fall. Multiple independent flexible support sleeves 2 can be adjusted to different heights under the drive of their corresponding electric push rods 3, thereby meeting the user's personalized needs for adjusting the pillow core height according to their own cervical curvature, sleeping posture, etc. For example, when lying on the back, the flexible support sleeves at the corresponding positions of the cervical spine can be adjusted. The height of the support sleeve 2 is adjusted to a suitable height. When lying on one's side, the height of the flexible support sleeve 2 on the side is adjusted accordingly to ensure that the cervical spine is always in a natural and comfortable physiological curve. The overload protection function can prevent damage caused by excessive extension or retraction of the electric push rod 3 due to operational errors, ensuring the normal operation and service life of the equipment. The flexible connector 4 located at the bottom of the flexible support sleeve 2 inside the pillow core body 1, together with the adjustment rope 5 passing through it, realizes the adjustment of the pillow core shape. The flexible connector 4 is made of flexible rubber, which has good flexibility and tensile strength. The anti-slip texture on the surface ensures the stability of the adjustment rope 5 when it moves within it. When the user pulls the adjustment ring 6, the adjustment rope 5 moves within the flexible connector 4. Because the flexible connector 4 and the flexible support sleeve 2 are arranged in a cross shape, the movement of the adjusting rope 5 will change the relative position and angle between adjacent flexible support sleeves 2. For example, pulling the adjusting rope 5 will bring the adjacent flexible support sleeves 2 closer together, and the corresponding part of the pillow core will bulge. Releasing the adjusting rope 5 will allow the adjacent flexible support sleeves 2 to return to their relative position, and the shape of the pillow core will change accordingly. In this way, the shape of the pillow core can be flexibly shaped according to the user's needs, better adapting to various posture changes of the human body during sleep. The elastic support body 7 inside the flexible support sleeve 2 is provided with a hardness adjustment cavity 8. The connecting pipe 9 on one side of the pillow core body 1 is connected to the hardness adjustment cavity 8, and the connecting pipe 9 is provided with an electromagnetic flow control valve. The elastic support body 7 adopts a memory Made of a blend of sponge and elastic silicone, the pillow's firmness adjustment chamber 8 is filled with a fluid material (such as gas) and connected to an external device (such as an air pump) via a connecting pipe 9. When the user needs to adjust the pillow's firmness, they can remotely control the electromagnetic flow control valve via an external remote. After opening the valve, the external device injects fluid into the firmness adjustment chamber 8 through the connecting pipe 9. As the fluid in the chamber increases, the firmness of the elastic support 7 increases accordingly. Conversely, removing the material from the firmness adjustment chamber 8 will decrease the firmness of the elastic support 7. This precise control of the flow rate of the medium entering or leaving the firmness adjustment chamber 8 can meet the user's personalized needs for pillow firmness, further improving sleep comfort and cervical spine protection.
