Description

This utility model belongs to the technical field of pillows, and in particular to coil pillows.

The primary role of a pillow is to protect the cervical spine and allow the user to sleep well. If a pillow is not used when sleeping, the physiological curvature of the cervical spine may decrease and eventually become straight. If this condition continues for a long period of time, it may cause pain and discomfort, and may lead to autonomic nervous system symptoms such as numbness and vomiting. Therefore, it is important to choose an appropriate pillow when sleeping, and the structure of the pillow itself is also important. If the support areas for back sleeping and side sleeping are not compatible with the biomechanics of the human body, adequate sleep quality cannot be ensured.

Pillows act as a cushion when you change positions or move your body during the night. Many people gradually change from lying on their backs to lying on their sides when they first fall asleep. When this happens, having a pillow under your head can significantly mitigate the impact of the position change, reducing the impact on your head and resulting in better quality sleep.

The weight of an adult's head is approximately 4.5 to 5.5 kg, accounting for approximately 7.7% of an adult's body weight. From a biomechanical perspective, while the head weight itself remains constant, the load on the cervical spine changes depending on the angle at which the head is tilted. The greater the forward tilt angle of the head, the greater the strain on the neck. Therefore, when sleeping, it is necessary to use a pillow that can maintain the normal physiological curvature of the cervical spine, allowing the head to be supported comfortably.

Pillows made using conventional technology, such as memory foam pillows, have the disadvantages of poor heat dissipation and, if the memory foam urethane is not properly treated, having a strong odor and requiring deodorization before use. Feather pillows are expensive and, if not properly treated, are prone to emitting an unpleasant odor. Buckwheat husk pillows have the disadvantage that the filling is not fixed, making them prone to noise when the head moves, and are prone to the infestation of pests and the proliferation of bacteria if not dried in the sun. In addition, many conventional pillows have problems such as being too hard or too soft, or not providing enough support.

This utility model provides a coil pillow, which aims to solve the problems of conventional pillows, such as being too hard or too soft, having poor elasticity, support, breathability, and durability, being prone to deformation over long periods of use, and being prone to generating noise during use, resulting in poor applicability. This provides a coil pillow that has good elasticity, support, breathability, and durability, is resistant to deformation, and is quiet.

To achieve the above objectives, the present invention adopts the following technical solutions:
The coil pillow comprises a pillow cover, a pillow core, and a coil unit. The pillow cover is removably attached to the outside of the pillow core, and a cavity is provided inside the pillow core. The coil unit includes a coil and a coil cover, and the coil cover is provided to cover the outside of the coil. At least two coil units are provided, and the multiple coil units are arranged in a matrix, with the coil covers of adjacent coil units connected to each other.

In the coil pillow of this utility model, the pillow cover is used to protect the pillow core, which supports the head and houses the coil unit in a cavity provided inside. The coils of the coil unit are used to improve the pillow's elasticity, support, breathability, and durability, and to make it less likely to deform. Each coil cover individually covers and protects its corresponding coil, preventing contact and collision between adjacent coils and improving quietness. It also prevents damage to adjacent coils, improving durability and service life.

Preferably, the cavity is located in the center of the pillow core.

Preferably, the pillow core is composed of two parts, an upper part and a lower part, and a groove is formed on the contact surface of each of the upper and lower parts, and these two grooves combine to form the cavity.

Preferably, the cavity is formed as a rectangular cavity.
Preferably, the pillow core is made of a flexible filling material.

Preferably, the pillow core is made of latex or sponge material.
Preferably, the coil cover is formed as a sleeve made of nonwoven fabric.

Preferably, the coil cover is formed in a cylindrical shape, and adjacent coil covers are connected to each other by sewing.

Preferably, the coil is connected to the inner wall of the coil cover.

Preferably, the upper and lower ends of the coil are connected to the upper and lower inner walls of the coil cover by stitching, respectively.

The beneficial effects of this utility model are as follows:
1. The coil pillow of this utility model has independent coil units inside the pillow core, and multiple coil units are arranged in parallel and in a matrix to form the pillow's core support structure. This allows for dynamic mechanical support utilizing the deformation and restoring force of the coils. This allows the pillow to improve its ability to conform to the head through the elasticity of the coils. As a result, it is possible to eliminate the problems of prior art pillows, such as being too hard or too soft, having insufficient elasticity and support, and being prone to deformation with long-term use. It is also possible to provide a pillow with good elasticity and support that is resistant to deformation even with long-term use. Furthermore, it is possible to provide continuous, self-adaptive dynamic support. This allows for appropriate support to be applied according to the contours and weight of the human body. This allows for effective support of the head and neck and maintenance of the natural curvature of the spine, whether sleeping on one's back or on one's side. As a result, it reduces strain on the neck and back, contributing to fatigue relief.

2. The coil pillow of this utility model has an internal coil unit that allows for improved air circulation. This allows for a cool feeling even in the hot summer months, effectively preventing excessive temperature increases in the head. Furthermore, this structure inhibits the growth of bacteria and mites, contributing to the maintenance of healthy skin.

3. The coil pillow of this utility model has high elasticity and durability due to the coil unit located inside the pillow core. Even with long-term use, it is resistant to sagging and deformation, allowing for the maintenance of a comfortable sleeping environment over long periods of time. The coil unit also has excellent recovery performance, quickly returning to its original shape even when compressed. Experiments have confirmed that the coil pillow of this utility model does not sag even after being subjected to a 25 kg impact compression and 100,000 impact tests, and has a rebound rate of over 98%.

4. The coil pillow of this utility model eliminates the drawbacks of conventional filling materials, such as the tendency for them to collapse and the delayed response of memory foam materials, and the physical properties of the independent coils provide support that changes instantly and dynamically in response to pressure, preventing a decrease in support throughout the sleep cycle.

5. The coil pillow of this utility model can solve the problems of noise and excessive hardness that are present in conventional coil pillows. By encasing each coil independently within a coil cover, friction noise between the metal coils is suppressed, preventing the generation of noise and improving comfort.

6. The coil pillow of this utility model can use a flexible material for the pillow core, and by forming a flexible buffer layer on the outside of the coil unit, it feels soft to the touch and prevents excessive hardness.

7. The coil pillow of this utility model allows users to select the hardness of the coils according to their preferences and needs. Users who prefer a soft pillow can select relatively soft coils. On the other hand, users who require more support can select relatively hard coils. This flexibility in coil selection makes it possible to provide a coil pillow that can adapt to the sleeping needs of a variety of users.
