Description

Technical Field

[0001] The utility model relates to the technical field of cervical pillows, in particular to a cervical pillow. Background Art

[0002] Cervical spondylosis is a common disease that almost everyone will inevitably face. However, cervical spondylosis is almost a difficult problem that has not been well solved by today's medicine.

[0003] The pathological process of cervical spondylosis is quite complex, with various factors contributing to its development. For example, prolonged sitting, especially with the head bent over for repetitive tasks, can strain the muscles and ligaments at the back of the neck, leading to gradual degenerative changes. Excessive stress on the cervical spine can cause deformation of the intervertebral discs, straightening the cervical curvature and, in severe cases, forming a convexity. Chronic weight-bearing can also reduce and narrow the gap between the atlas and axis vertebrae, compressing the vertebral arteries and hindering normal blood flow.

[0004] An adult sleeps 6 to 9 hours a day, meaning they spend 1 / 4 to 1 / 3 of their time resting on a pillow. Therefore, using a pillow that meets the physiological requirements of the cervical spine is crucial for the treatment and prevention of cervical spondylosis and cannot be replaced by medication. When a person is soundly asleep, the neck and shoulder muscles completely relax, relying solely on the elasticity of the intervertebral ligaments and joint capsules to maintain the normal relationship between the intervertebral structures. Long-term use of an inappropriate pillow can cause excessive flexion in certain areas of the cervical spine, stretching and damaging the ligaments and joint capsules in these areas, leading to cervical instability and joint dislocation, which can eventually lead to cervical spondylosis.

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 1-3 As shown, the embodiment of the utility model discloses a cervical pillow, comprising:

[0049] The pillow body 1 is configured as a cylinder;

[0050] The heating component 2 includes a face cloth 21, a heating plate 22, an insulating pad 23 and a base cloth 24. The base cloth 24 covers the pillow body 1. The insulating pad 23 is arranged around the face cloth 21. The heating plate 22 is arranged around the insulating pad 23. The face cloth 21 is arranged around the heating plate 22.

[0051] The cylindrical pillow body 1 has an auxiliary therapeutic effect on the kyphosis of the cervical spine. At the same time, when the user uses the cervical pillow, the surface cloth 21 of the cervical pillow contacts the skin of the cervical spine of the human body, and the heating plate 22 emits heat and transfers it to the surface cloth 21. The heat is transferred to the cervical spine through the surface cloth 21, thereby accelerating the blood circulation in the cervical spine. At the same time, the thermal insulation pad 23 can prevent the heat emitted by the heating plate 22 from diffusing to the pillow body 1 to avoid heat waste, so that the heat emitted by the heating plate 22 can be transferred to the cervical spine to the maximum extent.

[0052] The material of the heating sheet 22 is graphene. The graphene heating sheet 22: 1. Efficient heating: The graphene heating sheet 22 can heat quickly and efficiently, does not require preheating time, and can reach a high temperature in a short time; 2. Low energy consumption: The graphene heating sheet 22 has a large heating area and high heating efficiency, and can work at low voltage, thereby reducing energy consumption and reducing energy waste; 3. Good stability: The graphene heating sheet 22 can work stably for a long time under extreme temperatures, is not easy to crack or deform, has a long life, and has a long service life.

[0053] The thermal insulation pad 23 can be made of EVA (ethylene-vinyl acetate copolymer), which has many advantages such as cushioning, waterproof and moisture-proof, shockproof, soundproof, heat-insulating, heat-insulating, good plasticity, strong toughness, recycling, environmental protection, impact resistance, anti-slip and strong shockproof capabilities. EVA material also has good chemical resistance, and is non-toxic, non-absorbent and soft on the surface, so it can be well set around the surface cloth 21 without causing harm to the human body.

[0054] It should be noted that the length of the pillow body 1 is 20-25 cm, and the diameter of the pillow body 1 is 6-10 cm, which is ergonomic. This length range can meet the needs of all people and is easy to carry.

[0055] like Figure 2-3 As shown, the pillow body 1 includes:

[0056] The cover 11 includes a first end portion 111 and a first connecting portion 112 extending from an edge of the first end portion 111;

[0057] The bottom cover 12 includes a second end portion 121 and a second connecting portion 122 extending from an edge of the second end portion 121;

[0058] The main body 13 has third connecting parts 131 at both ends thereof. The first connecting part 112 and the second connecting part 122 are fixedly connected to the third connecting part 131 at both ends respectively.

[0059] It should be noted that the top cover 11 and the bottom cover 12 can be PC / ABS (a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer), which has good impact resistance, heat resistance, chemical corrosion resistance and mechanical strength, and also has excellent anti-fouling properties. It can effectively resist the adhesion of pollutants such as stains, grease and fingerprints, keeping the surface clean and beautiful.

[0060] The first connecting portion 112 and the second connecting portion 122 are fixedly connected to the third connecting portion 131 at both ends respectively, so that the surface cover 11 and the bottom cover 12 are fixedly connected to the main body 13 at both ends to form the pillow body 1.

[0061] The first connection portion 112 and the second connection portion 122 may be external threads, and the third connection portion 131 may be internal threads. The first connection portion 112 and the second connection portion 122 are respectively threadedly connected and fixed to the third connection portion 131 .

[0062] Alternatively, the first connection portion 112 and the second connection portion 122 may be internal threads, the third connection portion 131 may be external threads, and the first connection portion 112 and the second connection portion 122 are respectively threadedly connected and fixed to the third connection portion 131 .

[0063] Or, as Figure 2As shown, the first connection portion 112 , the second connection portion 122 and the third connection portion 131 are all snap fasteners. The first connection portion 112 is snap-fitted to the third connection portion 131 , and the second connection portion 122 is snap-fitted to the third connection portion 131 .

[0064] By making the first connection part 112 , the second connection part 122 and the third connection part 131 all buckles, the first connection part 112 is snapped with the third connection part 131 , and the second connection part 122 is snapped with the third connection part 131 , which facilitates the assembly and disassembly of the top cover 11 and the bottom cover 12 from the body 13 .

[0065] Further, if Figure 2-3 As shown, the cervical pillow also includes:

[0066] Circuit board 3, on which an indicator light 31, a button module 32 and a charging module 33 are integrated;

[0067] The circuit board 3 is fixedly connected to the cover 11. The cover 11 is provided with an indicator light 31 through hole, a button through hole and a charging interface. The indicator light 31 is at least partially accommodated in the indicator light 31 through hole. The button through hole accommodates a button 34. The button 34 abuts against the button module 32. The charging module 33 is connected to the outside world through the charging interface.

[0068] The state of the cervical pillow is adjusted through the button module 32 . For example, a short press of the button 34 can realize the key switch of the heating plate 22 , and a long press of the button 34 can realize the temperature adjustment of the heating plate 22 .

[0069] The indicator light 31 can make the user aware of the status of the cervical pillow. Figure 3 As shown, in some embodiments, there are eight indicator lights 31, four of which are used to indicate the power level, and the remaining four are used to indicate the heating temperature of the heating plate 22. The four indicator lights 31 used to indicate the power level represent 25%, 50%, 75% and 100% of the power level respectively, and the four indicator lights 31 used to indicate the heating temperature represent the temperatures of 39°C, 41°C, 43°C and 45°C respectively. The cover 11 is laser-engraved with corresponding text labels at the positions corresponding to the indicator lights 31 for the convenience of the user. The user can adjust the heating temperature by long pressing the button 34. It should be noted that the indicator light 31 is a light emitting diode.

[0070] The charging module 33 can be connected to an external charger to charge the cervical pillow. For example, when the color of the indicator light 31 changes at 25%, it indicates that the battery is low. The user can use a charger to plug it into the charging port to charge the cervical pillow. The charging module 33 can be Micro USB (Micro-B), USB Type-C, or Lightning. In this embodiment, Type-C is preferred.

[0071] like Figure 2-3 As shown, in some embodiments, it also includes:

[0072] Dust plug 35 is placed on the charging port when it is not in use and is removed when it is in use. This prevents foreign matter from entering the charging port, preventing it from becoming clogged and damaged.

[0073] Further, if Figure 2-3 As shown, the cervical pillow also includes:

[0074] The power supply assembly 4 includes a battery box 41 and a battery 42. The battery box 41 is accommodated in the cavity of the main body 13. The battery box 41 is fixedly connected to the cover 11. The battery 42 is accommodated in the accommodating cavity of the battery box 41. The battery 42 is electrically connected to the circuit board 3.

[0075] The battery 42 is electrically connected to the circuit board 3 and is used to power the components integrated on the circuit board 3. By accommodating the battery box 41 in the cavity of the body 13 and the battery 42 in the accommodating cavity of the battery box 41, the space of the cervical pillow is saved.
