Abstract
Description
Technical Field
[0001] This utility model relates to the field of household goods technology, and in particular to a three-layer composite pillow. Background Technology
[0002] At the same time, due to the significant differences in the physiological curves of the head, neck, and shoulders, a single-density memory foam pillow cannot provide differentiated support, which can easily cause the neck to be suspended and lack effective support, while also causing excessive pressure on the fossa, exacerbating the user's discomfort during sleep.
[0003] Regarding breathability, while some memory foam pillows employ perforated designs to enhance airflow and address the stuffiness caused by their dense material, this approach only achieves limited breathability. During extended sleep, it remains insufficient to effectively alleviate heat and moisture buildup around the head and neck. Furthermore, traditional pillows generally suffer from a lack of diverse structural design, failing to accommodate users' preferences for side, back, and stomach sleeping positions. Their limited overall firmness adjustment range also hinders the maintenance of optimal comfort and support across different sleeping postures, ultimately failing to fundamentally address issues such as poor sleep quality and cervical spine health risks. Therefore, improvements through innovative technologies and structural designs are urgently needed. Utility Model Content
[0004] To overcome the technical defects of the existing technology, this utility model provides a three-layer composite pillow, which can solve the problems of reduced support and single function after enhanced breathability in the existing technology, and cannot meet people's differentiated support needs for the head, neck and shoulders.
[0005] The technical solution adopted by this utility model is as follows: A main pillow is formed by stacking an upper layer, a middle layer, and a support layer from top to bottom. The total height of the main pillow is 100mm, with the upper layer being 60mm, the middle layer 30mm, and the support layer 40mm. All parts of the main pillow use breathable slow-rebound memory foam. The upper layer uses 40D density, 45N indentation hardness slow-rebound memory foam; the middle layer uses 40D density, 70N indentation hardness slow-rebound memory foam; and the support layer uses 40D density, 55N indentation hardness slow-rebound memory foam. The upper layer, the middle layer, and the support layer are connected by... An environmentally friendly adhesive is used for composite bonding. The upper layer has a neck support area on one side, located at the front edge of the upper layer. The rear edge of the upper layer has a side sleeping area. The neck support area has a curved bulge height of 15-20mm to match the physiological curvature of the C3-C7 cervical vertebrae. The side sleeping area has a curved amplitude of 10-15mm to provide space for ear avoidance. The middle layer has a fossa area located between the neck support area and the side sleeping area. The bottom of the middle layer has a lower convex part with a group of gradually changing holes that penetrate the middle layer laterally.
[0006] Preferably, the upper layer and the support layer are together wrapped around the middle layer, the front and rear portions of the upper layer are in contact with the upper surface of the support layer, the environmentally friendly adhesive is continuously coated at the contact edge between the upper layer and the support layer, and the environmentally friendly adhesive is selectively coated between the upper layer and the middle layer, and between the middle layer and the support layer.
[0007] Preferably, the gradient hole group includes a main transverse hole located at the center of the lower convex portion, and secondary holes with gradually decreasing diameters are provided on both sides of the main transverse hole. There is at least one secondary hole on each side of the main transverse hole. The diameter of the main transverse hole is 15mm, the diameter of the secondary hole is less than or equal to 15mm, and the final diameter of the secondary hole is 10mm. This can reduce the hardness of the fossa region.
[0008] Preferably, the bottom of the upper layer and the top of the middle layer are both wavy curved cut surfaces.
[0009] Preferably, the top of the support layer has a top recess that fits into the lower protrusion, and the sidewall of the support layer has a series of long, circular, linear ventilation holes that penetrate the support layer.
[0010] Preferably, the elongated vent hole passes through the lower part of the top recess, and the elongated vent hole is 20mm long, 5mm wide, and 62mm apart.
[0011] Preferably, a through-bottom groove is provided at the bottom of the lower protrusion corresponding to the path of the elongated vent hole, and the through-bottom groove passes through the gradient hole group.
[0012] The beneficial effects of this utility model are:
[0013] 1. Meeting differentiated support needs: By using slow-rebound memory foam with different indentation hardness in the upper, middle and support layers, it can meet the differentiated support needs of the head, neck and shoulders, solving the problem of single function in the existing technology, improving the comfort of use, and meeting the needs of people for different softness and hardness, avoiding neck stiffness caused by insufficient neck support, and softening the fossa area to avoid compression of the fossa area.
[0014] 2. Enhanced breathability and support balance: The gradient hole group in the middle layer and the long strip ventilation hole design in the support layer enhance breathability while avoiding the problem of reduced support, achieving a good balance between breathability and support.
[0015] 3. Adapts to the physiological curves of the human body: The height of the bulge in the upper neck support area matches the physiological curvature of the C3-C7 cervical vertebrae, and the amplitude of the side sleeping area provides space for the ears to avoid impact, better conforming to the human body and improving sleep quality.
[0016] 4. Optimized structural design: The structure of the upper and supporting layers wrapping the middle layer, as well as the different coating methods between the layers, make the composite pillow structure more stable while maintaining good breathability. The wave-shaped curve cut surface design of the upper and middle layers further improves the overall performance. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1-5As shown, this embodiment provides a three-layer composite pillow, including a main body pillow formed by stacking an upper layer 1, a middle layer 2, and a support layer 3 from top to bottom. The total height of the main body pillow is 100mm, with the upper layer being 160mm, the middle layer 2 30mm, and the support layer 3 340mm. All parts of the main body pillow use breathable slow-rebound memory foam. The materials of each part of the main body pillow can be adjusted to other elastic materials such as latex as needed. The upper layer 1 uses 40D density, 45N indentation hardness slow-rebound memory foam; the middle layer 2 uses 40D density, 70N indentation hardness slow-rebound memory foam; and the support layer 3 uses 40D density, 55N indentation hardness slow-rebound memory foam. The upper layer 1 is bonded to the support layer 3 with an environmentally friendly adhesive. A neck support area 101 is provided on one side of the upper layer 1, located at the front edge of the upper layer 1. A side sleeping area 102 is provided at the rear edge of the upper layer 1. The height of the curve of the neck support area 101 is 15-20mm, which is used to match the physiological curvature of the C3-C7 cervical spine. The curve amplitude of the side sleeping area 102 is 10-15mm, which is used to provide space for the ears. A fossa area 201 is provided on the middle layer 2, located between the neck support area 101 and the side sleeping area 102. A lower convex part 202 is provided at the bottom of the middle layer 2, and a group of gradient holes 203 that penetrate the middle layer 2 laterally are provided on the lower convex part 202.
[0025] The upper layer 1 and the support layer 3 are wrapped together outside the middle layer 2. The front and rear parts of the upper layer 1 are in contact with the upper surface of the support layer 3. An environmentally friendly adhesive is continuously coated at the contact edge between the upper layer 1 and the support layer 3. An environmentally friendly adhesive is selectively coated between the upper layer 1 and the middle layer 2, and between the middle layer 2 and the support layer 3.
[0026] The gradient hole group 203 includes a main transverse hole located at the center of the lower convex part 202. There are secondary holes with gradually decreasing diameters on both sides of the main transverse hole. There is at least one secondary hole on each side of the main transverse hole. The diameter of the main transverse hole is 15mm, the diameter of the secondary hole is less than or equal to 15mm, and the final diameter of the secondary hole is 10mm. This can reduce the hardness of the pituitary region 201.
[0027] The bottom of the upper layer 1 and the top of the middle layer 2 are both wavy curved cut surfaces.
[0028] The top of the support layer 3 is provided with a top recess 301 that fits into the lower protrusion 202, and the side wall of the support layer 3 is provided with a straight row of circular long strip ventilation holes 302 that penetrate the support layer 3.
[0029] The elongated vent 302 passes through the lower part of the top recess 301. The elongated vent 302 is 20mm long, 5mm wide, and the spacing between the vents is 62mm.
[0030] A through-bottom groove is provided at the bottom of the lower protrusion 202 at the path of the elongated vent 302, and the through-bottom groove passes through the gradient hole group 203.
[0031] When using this three-layer composite pillow, users should use it according to their own sleeping posture and habits.
[0032] When in a supine position, the neck will come into contact with the neck support area 101 of the upper part 1. Since the curve of the neck support area 101 matches the physiological curvature of the human body's C3-C7 cervical vertebrae, the slow rebound memory foam will slowly deform according to the pressure and shape of the neck, providing precise support, keeping the cervical spine in a natural physiological state, and reducing neck muscle fatigue.
[0033] The head is placed in the fossa region 201 of the middle layer 2. The gradient hole group 203 reduces the hardness of the fossa region 201, reducing the pressure on the head. At the same time, air can circulate through the gradient hole group 203 and the long vent 302 of the support layer 3, keeping the air around the head fresh.
[0034] When adopting a side-lying position, the head rests on the side-lying area 102 of the upper part 1. The curved amplitude of the side-lying area 102 provides space for the ears to avoid being squeezed.
[0035] At the same time, the main pillow adapts to pressure, providing stable support for the shoulders and head, maintaining the body's balance and comfort.
[0036] During sleep, the human body generates heat and moisture. Air enters the pillow through the long, narrow ventilation holes 302 in the support layer 3, then circulates through the gradient hole group 203 in the middle layer 2, carrying away the heat and moisture, and finally exits through the long, narrow ventilation holes 302 at the bottom, achieving air circulation inside the pillow and keeping the sleep environment dry and comfortable.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of this utility model as claimed, which is defined by the appended claims and their equivalents.
