Description
Technical Field
The invention relates to the technical field of articles for daily use, in particular to a pillow.
Background
The person sleeps at night, typically in 5 to 6 (cycles of each sleep cycle of about 60 to 90 minutes). Studies have shown that the light sleep period and the light sleep period, which account for about 55% of the entire sleep time, have little effect on relieving fatigue, and only enter the deep sleep period to have a greater effect on relieving fatigue. Because the cortical cells are in a fully resting state in a deep sleep state, it has a critical effect on relieving fatigue, restoring energy, immunity, etc.
However, this deep sleep takes only 25% of the total sleep time. Therefore, the sleep quality is evaluated, and the length of the deep sleep time is finally considered. In sleep science, "deep sleep" is a deep rest where the brain does not play after you fall asleep. Deep sleep is also known as "golden sleep," which is commonly referred to as "golden sleep," golden sleep.
At present, a plurality of people are trouble for sleeping, and comfortable bedding, such as pillows, mattresses and the like, is provided. Can greatly improve sleep condition. Comfort is the subjective perception of a person and consists of both physiological and psychological factors. Taking a pillow as an example, the comfort level of the pillow is influenced by the material, structure, geometric dimension, shape and the like of the pillow. The pillow with good design should enable the user to have good body pressure distribution and touch feeling when lying on one's side and on one's back, so as to ensure the stable and comfortable posture of the user.
However, the memory pillow in the prior art is integrally formed on the surface, and a part of the supporting force on the head and the neck comes from the rebound of the memory pillow. When the head is pressed into the pillow, the head feels comfortable in a short time because the material absorbs kinetic energy and gravitational potential energy generated from the head contacting the pillow to stopping by its deformation. However, since the entire pillow is a uniform piece of memory sponge, only the portion of the surface contacting the head is deformed, and the overall shape of the pillow is not deformed adaptively. Although the pressure distribution state of the head of the user is improved, the pressure distribution of the neck and the shoulder of the user is not improved, and discomfort is brought to the user.

Detailed Description
In order to solve the technical problems set forth in the background art, the inventor of the present application conceived to divide the bottom of the pillow into two support blocks by a partition groove extending laterally from the bottom of the pillow, so as to change the pressure of the shoulder and neck of the user when using the pillow, thereby providing a more comfortable environment for the user. For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, 2A and 2B, the pillow provided by the present invention includes a support layer 10 and a contact layer 20 on the support layer 10. The bottom of the support layer 10 has a partition groove 11 extending in a lateral direction, and the bottom of the support layer 10 forms two support portions on both sides of the partition groove 11. According to the invention, the transverse extending separation grooves are formed, and the two supporting parts are formed at the two sides of the separation grooves, so that the thickness of the supporting layer in the middle area of the pillow is reduced, the middle of the pillow in a natural state is suspended, when a user uses the pillow, the middle area deforms greatly, the curve of the head of the user is more suitable, and the deformation of the edge area is small, so that the cervical vertebra and the shoulder of the user can be accurately supported.
Specifically, as shown in fig. 2A, 2B, 4A and 4B, when the user uses the pillow, the pillow is pressed downward, and the support portion provides a supporting force to the pillow. Meanwhile, as the head of the user is positioned in the middle area of the pillow, the supporting layer 10 in the middle area is sunk inwards to the separation groove 11, so that the middle part of the pillow is adaptively deformed to fit the head shape of the user. In addition, the cervical vertebra of the user is close to the edge area of the pillow, and the edge area deforms less due to the larger thickness, so that the cervical vertebra of the user is in a protruding shape relative to the middle area of the pillow, and the curvature of the cervical vertebra of the user is met, so that the pillow is attached to the curve of the cervical vertebra of the user. Because of the special structure of the small middle thickness and the large edge thickness of the pillow, the pillow can adaptively deform according to the respective weight of the head, the neck and the shoulders of a user, the contact area between the user and the pillow is increased, the pressure of the head, the shoulder and the neck is dispersed, the pressing sense of the head, the cervical vertebra and the shoulders of the user is reduced, and a more comfortable use environment is created for the user.
In order to ensure that the deformation of the middle area and the edge area of the pillow can meet the curve requirements of the head, neck and shoulders of a human body, the separation groove 11 is preferably arranged in an inverted V shape, so that an inverted V-shaped separation groove is formed. The inverted V-shaped separation grooves enable the thickness of the supporting layer 10 to gradually change, namely the thickness of the supporting layer 10 gradually increases from the middle area to the edge area, correspondingly, the deformation amount also gradually changes, and the supporting layer is more attached to the curved surface of the head. When the user uses the pillow, the head is generally positioned in the middle region of the pillow, the neck extends from the middle region to the edge region, and the shoulders are positioned in the edge region. The middle area is large in deformation, and can adapt to the arc shape of the head; the pillow extends from the middle area to the edge area, the deformation is gradually reduced, the surface of the pillow is transited into a curved surface shape, and the pillow can adapt to the curve of the neck and the shoulder of a human body, so that the pillow is more fit for a user; the small deformation of the edge region provides effective support to the shoulder to relieve head pressure. Therefore, the inverted V-shaped separation groove can enable the deformation of different areas to adapt to the curves of the head, neck and shoulders of a user, simultaneously provide different supporting forces for different human body parts, disperse pressure and improve comfort.
In the inverted V-shaped separation groove, the deformation amount and the supporting force of the supporting layer are influenced, and the angle of the V-shaped included angle in the inverted V-shaped separation groove is also influenced, namely the included angle of two groove edges of the inverted V-shaped separation groove. If the angle of the V-shaped included angle is too small, the thickness of each part of the supporting layer 10 corresponding to the V-shaped included angle is correspondingly increased, and although effective supporting force can be provided, the deformation amount of the pillow is limited, so that effective support cannot be provided for the neck and shoulder, and deformation corresponding to the head shape curve of a user cannot be formed; if the angle of the V-shaped included angle is too large, the thickness of each part of the supporting layer 10 corresponding to the V-shaped included angle is correspondingly reduced, and the corresponding deformation is too large, so that the head supporting force is reduced, and the neck supporting force is too large, so that the head, the neck and the shoulders of the user cannot be effectively supported.
Preferably, the angle of the V-shaped included angle may be selected in the range of 130 ° to 138 °. Specifically, as shown in fig. 2A, the included angle between the groove edge of the inverted V-shaped separation groove and the plane is 23 °, that is, the included angle of the V-shaped separation groove is 134 °. When the pillow is pressed, the supporting layer is sunk and deformed, the included angle between the groove edge of the inverted V-shaped separation groove and the plane can be changed to be within the range of 5-20 degrees, and the corresponding change range of the V-shaped included angle is 140-170 degrees. Namely, when the pressure is high, the included angle between the groove edge of the inverted V-shaped separation groove and the plane where the groove edge is positioned can be changed to 5 degrees, and the included angle of the V-shaped included angle is 170 degrees; when the pressure is smaller, the included angle between the groove edge of the inverted V-shaped separation groove and the plane can be changed to 20 degrees, and the included angle of the V-shaped separation groove is 140 degrees. It should be noted that the angle of the V-shaped included angle can be comprehensively selected according to the width and the height of the pillow. When the width of the pillow is larger and the height is lower, the angle of the V-shaped included angle is correspondingly selected to be larger, for example, 138 degrees; when the width of the pillow is smaller and the height is higher, the angle of the V-shaped included angle is correspondingly smaller, for example 134 degrees. In summary, it is necessary to ensure that the support layer 10 has a certain thickness to provide a sufficient supporting force to the user; while ensuring that the support layer 10 has a certain thickness gradient so that the support layer 10 can be deformed accordingly in response to the pressure applied. Thus, the V-angle needs to have a range of variation, which may be in the range of 30 ° to 35 °. For example, the V-shaped included angle is selected to be 135 °, i.e., the V-shaped included angle is 135 ° when the pillow is not under force. And after the supporting layer 10 is deformed, the V-shaped included angle can be gradually changed from 135 ° to 165 °, and even gradually changed to 170 °.
As shown in fig. 2A, 2B, 4A and 4B, the top of the inverted V-shaped separation groove is provided with an arc transition portion 12, so that the top of the inverted V-shaped separation groove is prevented from being a sharp corner, and the internal stress is prevented from being larger and torn due to the concentration of the top stress when the pillow is pressed. By arranging the arc transition part 12, the problem of stress concentration can be effectively solved, the stress in the pillow is dispersed, the arc line is deformed along with the change of the stress, and the problem of tearing of the supporting layer is effectively solved.
Preferably, in order to enable the pillow to more conform to the curve between the cervical vertebrae and the shoulders, appropriate treatments are performed at the edges of the contact layer 20 and the bottom edge of the support layer 10.
Specifically, the first chamfer 23 is provided at the edge of the contact layer 20, and the angle of the first chamfer 23 may be 155 ° to 165 °, i.e., the chamfer plane forms an angle of 155 ° to 165 ° with the plane of the contact layer 20. When the user uses the pillow, the head is positioned in the middle area of the pillow, the neck is positioned between the middle area and the edge area, and the shoulders are generally attached to the edge of the pillow. From the human body structure, the neck and the shoulder are connected in a curve way, so that the first chamfer angle 23 is arranged at the edge of the pillow, so that the pillow presents gradual transition change at the edge instead of vertical change, so as to be attached to the curve between the neck and the shoulder of the human body, adapt to the human body engineering structure, increase the contact area between a user and the pillow, and reduce the pressure of the neck and the shoulder of the user. Of course, the edge of the contact layer 20 may be provided with a first rounded corner, and the radius of the first rounded corner may be 45 to 65mm, so that the pillow may have a circular arc transition at the edge, and fit the curve between the neck and the shoulder of the user.
More preferably, a second chamfer 13 may be provided at the bottom edge of the support layer 10 to reduce the thickness of the bottom edge of the support layer 10. The shoulders of a user typically rest against the edges of the pillow when the user is using the pillow. The provision of the second chamfer reduces the thickness of the edge of the support layer 10 so that the pillow edge can be deformed adaptively according to the weight of the user's shoulders to conform to the curve of the user's shoulders, reducing the compression of the pillow edge against the user's shoulders. The angle of the second chamfer 13 may be 135 deg. to 155 deg., i.e. the chamfer plane is at an angle of 135 deg. to 155 deg. to the bottom surface of the support layer 10. The smaller the chamfer angle, the more the thickness is reduced; the greater the chamfer angle, the greater the chamfer plane, and the wider the extent, making the edge more prone to deformation. Of course, a rounded corner may be provided at the bottom edge of the support layer 10, and the radius of the rounded corner may be 45 to 65mm. Chamfer and fillet all can reduce the thickness of supporting layer 10 bottom edge to make supporting layer 10 edge more yielding, laminating user's shoulder curve, thereby increase area of contact reduces the pillow and to the sense of oppression of shoulder, improves user experience.
Generally, in order to maintain a good supporting effect and to satisfy comfort in use, the supporting layer 10 and the contact layer 20 are made of different materials, and the hardness of the two materials is not consistent. Specifically, in the present invention, the hardness of the support layer 10 is greater than the hardness of the contact layer 20. The supporting layer 10 can be made of polymer sponge, and has high density and high rebound resilience. The high density ensures that the support layer 10 has sufficient rigidity to provide effective support. Meanwhile, the high rebound resilience can enable the pillow to have stronger recovery capability, namely, after a user uses the pillow, the pillow can quickly recover to the original state.
The contact layer 20 is in direct contact with the head, neck and shoulder of the user, has good elasticity, and can provide soft and comfortable touch feeling for the user. The contact layer 20 is generally made of a slow rebound memory sponge, has good touch feeling and soft material, and can remarkably reduce pressure and improve use comfort of a user.
On the other hand, pillows are typically used for a long period of time, for example 7-8 hours at night when sleeping. In order to avoid the stuffy feeling caused by the long-time use of the pillow, especially when the contact layer is better in fit due to the slow rebound memory, the pillow needs to have good heat dissipation capability and permeability.
In order to provide the pillow with good heat dissipation, the contact layer 20 is preferably provided in two parts, comprising a first contact layer located on the surface of the pillow in direct contact with the skin and a second contact layer located on the lower part of the first contact layer. The first contact layer is used for increasing heat dissipation and relieving stuffiness of the pillow, and the second contact layer is used for providing good elasticity so that the contact layer 20 is softer and more comfortable. The first contact layer can be made of slow rebound materials added with silicon, such as polyurethane added with silicon, so that the heat absorption and release rate of the materials can be accelerated, good heat conductivity is achieved, and the stuffiness of a user using the pillow is reduced. The second contact layer can adopt a slow rebound material, such as a slow rebound sponge in a temperature-sensitive decompression material, can absorb energy brought by impact, has better elasticity and deformability, ensures the softness of the contact layer 20, and improves the comfort and the use experience of a user.
In order to make the pillow have good permeability, the pillow of the invention is provided with a ventilation structure. The first venting structure is located on the side of the pillow as shown in figures 5 and 6. Specifically, an inner groove 30 recessed toward the inside of the pillow is provided at the side of the pillow so that air can circulate therein in the direction indicated by the arrow at the side of the pillow in fig. 5 and 6. Due to the existence of the inner groove 30, when a user uses the pillow, the shoulder cannot be completely clung to the side part of the pillow, air is filled in the inner groove 30 and freely circulates in the inner groove, heat on the surface of the user is taken away, the surface temperature of the user is reduced, and the stuffiness is greatly reduced.
In addition, by arranging the inner groove 30 and matching the first chamfer 23 and the second chamfer 13, the supporting force of the side edges can be reduced, so that the pillow can more effectively support the neck and the shoulder, the inner groove 30 is positioned in the middle of the contact part, and even if being pressed, the inner groove is not completely closed, thereby ensuring the ventilation effect.
Preferably, the inner groove 30 is a V-shaped inner groove, the opening of which is directed to the outside of the pillow, i.e., the V-shaped inner groove gradually decreases in width from the outside of the pillow to the center groove, and the thickness of the pillow side gradually increases from the outside to the center, ensuring the supporting effect of the pillow side on the user's shoulder.
The second venting structure is disposed on the contact layer 20 as shown in fig. 3 and 6. Specifically, at least one first incision 21 and a plurality of second incisions 22 intersecting the first incision 21 are provided on the contact layer 20; the first and second slits 21 and 22 divide the contact layer 20 into a plurality of triangular contact blocks. When a user uses the pillow, air can circulate in the grooves, and the circulation direction is the direction indicated by the arrow of the contact layer 20 in fig. 6, so that the permeability of the head of the user is ensured, and the stuffiness is reduced.
Preferably, the first slots 21 extend transversely through the contact layer 20 and communicate with the environment outside the pillow, allowing for more unobstructed air flow between the slots. If the pillow is wider in the longitudinal direction, a plurality of first slits 21 may be provided to increase the passage of air. The second slit 22 includes a first direction slit 221 extending in a first direction and a second direction slit 222 extending in a second direction, and the first direction slit 221 and the second direction slit 222 intersect to form an X-shape. The first slots 21 extend transversely through the contact layer 20 to provide a primary path for air flow through the ventilation structure. The second slot 22 is an important component of the ventilation structure, and two slots with different directions are arranged, so that air circulation has various circulation modes, and air convection is kept smooth. Meanwhile, the pillow can also cover all parts of the pillow, and the pillow is ensured to have good ventilation performance.
The depth of the first kerf 21 is greater than the depth of the second kerf 22. Meanwhile, the depth of the first kerf 21 is smaller than the thickness of the contact layer 20. The first incision 21 extends transversely through the contact layer 20 and is intended to be a major component of the ventilation structure to a sufficient depth to allow more air to enter the ventilation structure. Meanwhile, the width of the notch of the first notch 21 is larger than or equal to that of the notch of the second notch 22, so that the reliability of the ventilation structure is ensured. Since the first grooves 21 are provided on the contact layer 20, the depth is not preferably larger than the thickness of the contact layer 20, so that the contact layer 20 is prevented from being laterally cut.
The first slot 21 and the second slot 22 are U-shaped slots, and the slot walls of the U-shaped slots are vertical slots. When the U-shaped groove is pressed, only the groove wall close to the groove opening is deformed into the groove, the groove bottom is sealed into a tubular channel, and air can freely circulate in the tubular channel. If the V-shaped groove is formed, when the pressure of the head of a user is received, the groove wall deforms outwards, the head of the user is directly attached to the V-shaped groove, air cannot circulate in the groove, and ventilation cannot be guaranteed. Therefore, the U-shaped groove can ensure the reliability of the ventilation structure, so that the ventilation structure has good performance, and the stuffiness of the pillow is effectively reduced.
The first and second slits 21 and 22 divide the contact layer 20 into triangular contact pieces in addition to having a ventilation effect. Each triangular contact block can form an independent stress unit, can correspondingly deform according to the weight received by each part, and ensures that a good supporting effect is formed for a user. After the surface of the contact layer 20 is cut three-dimensionally, the independent triangular contact blocks can be deformed according to actual stress. Each triangular contact block forms a stress system, and plays roles of absorbing pressure and providing support.
Preferably, the first direction slits 21, 221 and 222 form an equiangular distribution in the center of the pillow. As shown in fig. 3, when the user uses the pillow, the head is positioned at the middle part, and the sharp corners of the triangular contact blocks are pressed and deformed into the grooves. Since the first grooves 21, the first direction grooves 221 and the second direction grooves 222 are distributed and intersected at equal angles to form a uniformly distributed triangle structure, the triangular contact blocks have no influence of the mutual restriction of elastic force, and deform, so that a curved surface which is more attached to the shape of the head can be formed. Moreover, the triangular contact blocks are not mutually held by elastic force, so that the tight-clamping state of the pillow on the head is released, and more comfortable experience is brought to the user.
It should be noted that, in the process of changing the sleeping posture of the user, the contact layer 20 subjected to surface cutting can flexibly adjust different stress units according to different positions of the head and the neck so as to complete the deformation and supporting process. As shown in fig. 4A and 4B, the user has a small difference in height between the head and the back when sleeping on his back, and the head needs to bear a weight greater than the weight of the head. At this time, the pillow is stressed greatly, and the deformation of the contact layer 20 and the support layer 10 is correspondingly large, so that the pillow shape accords with the posture of a user when sleeping on the back, and the sleeping quality is ensured. When the user sleeps on the side, the height difference between the head and the back of the user is large, the weight required to be born by the head is only the weight of the head, at the moment, the pillow is small in stress, the deformation of the contact layer 20 is small, and the head of the user can be kept straight. The deformation of the supporting layer 10 is small, so that the height of the pillow is consistent with the shoulder width of the user, the shape of the pillow is consistent with the shape of the user when the user sleeps on the side, and the sleeping quality of the user is ensured. Therefore, after the contact layer 20 is cut on the surface, the deformation of the pillow is correspondingly changed when the user changes the sleeping position, so that the sleeping quality is not affected, the user feels comfortable on the head and the neck, and the user experience is good.
In summary, according to the technical scheme of the invention, the pillow comprises a supporting layer and a contact layer positioned on the supporting layer, wherein the bottom of the supporting layer is provided with a separation groove extending transversely, and two supporting parts are formed at two sides of the separation groove at the bottom of the supporting layer. According to the pillow, the separation groove is formed, the supporting part bears the supporting function of the pillow, the thickness of the supporting layer in the middle area of the pillow is reduced, and the middle of the pillow in a natural state is suspended. When a user uses the pillow, the supporting layer is pressed to deform in the separation groove, the upper part of the separation groove corresponds to the head position, the deformation is relatively large, the upper part of the supporting part corresponds to the neck position, the deformation is relatively small so as to adapt to the curves of the head and the shoulder and the neck of the user, and the contact layer can be completely attached to the curves of the head and the shoulder and the neck of the user to form effective support. Meanwhile, the stress area of the user is increased, so that the pressure distribution of the shoulders and the neck of the user can be dispersed, the pressing sense is reduced, the comfort of the user is improved, and the user can relax when using the pillow.
The foregoing is merely a specific embodiment of the invention and other modifications and variations can be made by those skilled in the art in light of the above teachings. It is to be understood by persons skilled in the art that the foregoing detailed description is provided for the purpose of illustrating the invention more fully, and that the scope of the invention is defined by the appended claims.
