Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of bedding, in particular to a pillow core. BACKGROUND
[0002] The existing silica gel cotton (full name silica gel sponge, which is made of silica gel and sponge according to a certain proportion) pillow core has the following defects:
[0003] 1. Insufficient head and neck fitting degree and wrapping feeling: the existing ergonomic silica gel pillow is mostly designed with a "B-type" curve, which can meet the different heights for sleeping, but the pillow surface is too wide to fit the head and neck curve more accurately, especially when sleeping, the head wrapping feeling cannot be formed.
[0004] 2. Poor air permeability: the single ergonomic curve pillow surface is weaker in internal air flow compared with the double curve ergonomic pillow surface after being covered with a pillowcase, so the human body has the problem of insufficient air permeability and stuffiness when sleeping. INVENTION CONTENTS
[0005] The utility model aims at providing a double curve ergonomic neck protection pillow core to solve at least one of the above technical problems.
[0006] The technical problem solved by the utility model can be solved by the following technical scheme:
[0007] The front surface of the double curve ergonomic neck protection pillow core is provided with three arc protrusions from front to back, which are a first arc protrusion, a second arc protrusion and a third arc protrusion, the height of the first arc protrusion is greater than that of the third arc protrusion, the height of the third arc protrusion is greater than that of the second arc protrusion, and the two adjacent arc protrusions are arc grooves.
[0008] Preferably, the height of the first arc protrusion is 80mm±5mm.
[0009] Preferably, the height of the third arc protrusion is 100mm±5mm.
[0010] Preferably, the height of the second arc protrusion is 60mm±5mm.
[0011] Preferably, the minimum distance from the groove bottom of the arc groove to the back surface of the double curve ergonomic neck protection pillow core is 50mm±5mm.
[0012] Preferably, the distance between the groove walls of the arc groove is smaller closer to the groove bottom.
[0013] Preferably, the distance between the groove walls of the arc groove is 15mm-25mm.
[0014] The double curve ergonomic neck protection pillow core is made of high-elasticity silica gel cotton.
[0015] The hyperbolic ergonomic neck protection pillow core has a density of 60D±5% and a resilience of ≥85%.
[0016] Preferably, the hyperbolic ergonomic neck protection pillow core is provided with an upper and lower through hole.
[0017] Further preferably, the density of the through hole gradually decreases from the bottom of the arc-shaped groove to the top of the arc-shaped protrusion.
[0018] Beneficial effects:
[0019] 1. Ergonomic optimization: On the basis of maintaining the ergonomic neck curve fit, the head ergonomic curve fit is increased, so that the overall sleep experience is better.
[0020] 2. Improved air permeability: The hyperbolic structure of the pillow core can create more space for air flow when the pillow cover is used, so the overall air permeability is improved, and the air permeability efficiency is increased by about 15% compared to traditional block cutting. BRIEF DESCRIPTION OF DRAWINGS
[0021] Figure 1 is a side view of the present utility model. DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to the drawings.
[0023] Referring to Figure 1 , the front of the hyperbolic ergonomic neck protection pillow core is provided with three arc-shaped protrusions from front to back, which are first arc-shaped protrusion 1, second arc-shaped protrusion 2 and third arc-shaped protrusion 3. The height of the first arc-shaped protrusion 1 (preferably 80mm±5mm, suitable for short-neck users) is greater than the height of the third arc-shaped protrusion 3 (preferably 100mm±5mm, suitable for long-neck users), and the height of the third arc-shaped protrusion 3 is greater than the height of the second arc-shaped protrusion 2 (preferably 60mm±5mm, for supporting the head transition area). Preferably, the extension directions of the three arc-shaped protrusions and the two arc-shaped grooves are the same as the extension direction of the long side of the hyperbolic ergonomic neck protection pillow core with longer length.
[0024] The two adjacent arc-shaped protrusions are arc-shaped grooves 4, and the minimum distance from the groove bottom of the arc-shaped groove 4 to the back of the hyperbolic ergonomic neck protection pillow core is 50mm±5mm. The distance between the groove walls of the arc-shaped groove 4 is smaller closer to the groove bottom, and the distance between the groove walls of the arc-shaped groove is 15mm-25mm, thereby forming an air flow channel and improving air permeability.
[0025] The back of the hyperbolic ergonomic neck protection pillow core is preferably flat. The hyperbolic ergonomic neck protection pillow core can be provided with upper and lower through holes, so as to further improve the air permeability by using the through holes. The through holes can be arranged at equal intervals. Preferably, the density of the through holes gradually decreases from the bottom of the arc-shaped groove to the top of the arc-shaped protrusion. Thus, the support force of the arc-shaped protrusion is ensured, and the air permeability of the head is increased.
[0026] The hyperbolic ergonomic neck protection pillow core is made of high-elasticity silica gel wool material with a density of 60D±5% and a rebound rate of ≥85%. The high-elasticity silica gel wool can be precisely formed into a curved surface structure through numerical control hot pressing cutting process (temperature 150℃±5℃, pressure 0.8MPa) to obtain the arc-shaped protrusion and the arc-shaped groove. The edge is smooth without burrs.
[0027] The curve parameters of the utility model are based on the Asian adult cervical curvature database (covering 90% of the cervical curvature range of the population), which can realize the hyperbolic collaborative fitting of the neck and the head, and take into account the wrapping feeling and the natural curvature of the cervical vertebrae.
[0028] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
