Detailed Description

Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.

Fig. 1 to 3 show schematic structural views of a breathable water-drop-shaped arched pillow core according to the present utility model. The breathable water-drop-shaped arched pillow core comprises a pillow core main body 11, a plurality of breathable grooves 12 formed in the pillow core main body 11 at intervals, and a plurality of supporting columns 13 formed in the pillow core main body 11 at intervals. It is conceivable that the breathable drop-shaped arched pillow core further includes other functional modules, such as a pillow case, a fixing structure, etc., which are known to those skilled in the art, and will not be described herein.

The pillow core main body 11 is a cuboid or other shape as a whole, and has a circular arc shape in the width direction to adapt to the neck structure of people. The pillow core main body 11 is a entity with radian on two flat sides in the middle, and is used for maintaining the flatness of the pillow core main body 11 after being sleeved on a pillowcase, and the comfort of a user during sleeping is increased by increasing the contact area with the user. The pillow core main body 11 may be made of soft material, and may be made of flexible sponge polyurethane, so as to provide elasticity and comfort for the user. When the pillow core main body 11 is used by a user, the pillow core main body 11 deforms to promote the ventilation grooves 12 arranged on the pillow core main body 11, and the support columns 13 play a corresponding role. The pillow core main body 11 includes a headrest surface 111, a bottom surface 112 provided opposite to the headrest surface 111, two cross sections 113 perpendicular to the extending direction of the ventilation grooves 12, and two side surfaces 114 parallel to the extending direction of the ventilation grooves 12. It is contemplated that the headrest face 111 is typically the side of a person's headrest. The bottom surface 112, the cross section 113, and the side surfaces 114 are structural surfaces, and are not described in detail herein. The headrest surface 111 is used for providing the ventilation groove 12 and the support column 13.

The ventilation slots 12 are provided on the headrest face 111 and both side faces 114. Openings at both ends of the ventilation slot 12 are provided on the cross section 113 or the side surface 114. The ventilation grooves 12 penetrate the pillow core body 11 along the arrangement direction of the two cross sections 113. In this embodiment, the extending direction of the ventilation slot 12 is a straight line, and it is conceivable that, according to practical situations, the extending direction of the ventilation slot 12 is not necessarily a straight line, but may be other shapes, such as a curve and an arc. On the cross section 113, the contour line of each ventilation slot 12 forms a drop-shaped pattern, that is, includes a circular arc section 121 disposed in a direction toward the bottom surface 112, and two S-shaped line sections 122 disposed on both sides of the circular arc section 121 and connected to the circular arc section 121. The outline of the ventilation slot 12 is an axisymmetric pattern, and the symmetry axis passes through the center of the circular arc section 121. When the user uses the pillow core main body 11, the pillow core main body 11 collapses or recovers, the ventilation groove 12 deforms, and then the opening and closing phenomenon is generated, so that the gas in the ventilation groove 12 moves along with the change of the pressure in the ventilation groove 12, fresh flowing air is provided for the user, and side sleeping is not smoldering.

The central angle of the arc section 121 is larger than 180 degrees, and the size of the central angle of the arc section 121 influences the shape and size of the ventilation groove 12. The circular arc section 121 may store air for the pillow core main body 11, and is used for performing gas exchange with air outside the pillow core main body 11, so as to increase air permeability of the pillow core main body 11.

The S-shaped line segment 122 may be an S-shaped line segment protruding toward the inside of the air-permeable groove 12, and connected to both ends of the circular arc segment 121 to form a neck portion of a drop-shaped contour line. When the user uses the pillow core main body 11, the pillow core main body 11 collapses by receiving a force applied from the user' S head perpendicular to the headrest surface 111, and the S-shaped line segment 122 is pressed to deform in a horizontal direction parallel to the headrest surface 111, so that the contact area between the user and the pillow core main body 11 in the horizontal direction can be increased.

Because the pillow core main body 11 is provided with a plurality of ventilation grooves 12 which are arranged at intervals, different supporting forces aiming at different positions can be provided for users by designing the depth values of the ventilation grooves 12. If the neck of the user needs to be provided with a little supporting force, the device also accords with the physiological structure of the human body, and the brain bag can be provided with a little supporting force, so that the user can rest fully. In the present utility model, therefore, in a cross section perpendicular to the extending direction of the ventilation grooves 12, a plurality of ventilation grooves 12 are connected to form an arc line 14 toward the lowest point of the bottom surface 112, and the arc line 14 also shows the depth of the ventilation grooves 12 from the headrest surface 111 of the pillow core main body 11 to the bottom surface 112. Of course, the arc 14 itself is not present, and is provided herein only to illustrate the configuration and distribution of the plurality of ventilation slots 12.

The depth of the ventilation grooves 12 is gradually reduced from the middle of the pillow core body 11 to the two sides, and the difference between the two sides is the same or different. It will be appreciated that the depth of the ventilation slots 12 decreases from the middle to the sides of the pillow core body 11 so that the arcs 14 are continuous arcs with a low middle and a high side. Through the design of the above structure, the arc 14 includes a middle arc section 141, and a first arc section 142 and a second arc section 143 respectively disposed at two sides of the middle arc section 141. The intermediate arcuate segment 142 has a positive curvature relative to the curvature of the ventilation slot 12. Because the first and second arcuate sections 142, 143 are oppositely facing to the opening of the intermediate arcuate section 141, the first and second arcuate sections 142, 143 have a negative curvature relative to the curvature of the ventilation slot 12.

The curvatures of the first and second arc segments 142, 143 may be the same or different. When the curvatures of the first and second arc sections 142 and 143 are different, the depth of the ventilation slots 12 respectively located on the first and second arc sections 142 and 143 is also different, so that the pillow core main body 11 is provided with different support columns 13 with different support strengths on two sides of the arc 14, and the headrest surface 111 provides different sleeping sensations for the user and has different support forces on different parts of the user.

The number of the supporting columns 13 is determined according to the number of the ventilation slots 12, and the supporting slots 13 are formed by cutting the ventilation slots 12, and the structure and shape thereof are not repeated. It is conceivable that the support column 13 is in the same direction as the air-permeable slot 12.

Compared with the prior art, the breathable water-drop-shaped arched pillow core provided by the utility model has the advantages that as the breathable grooves 12 are formed, when a user uses the pillow core main body 11, the pillow core main body 11 collapses or recovers, the breathable grooves 12 deform, and further a stretching phenomenon is generated, so that the gas in the breathable grooves 12 moves along with the change of the pressure in the breathable grooves 12, fresh flowing air is provided for the user, and the user is more comfortable to sleep, especially the user is not stuffy in sleeping on the side. Meanwhile, when the ventilation slots 12 are arranged, a plurality of ventilation slots 12 are connected on a section perpendicular to the extending direction of the ventilation slots 12 and at the lowest point facing away from the bottom surface 112 to form an arc line 14, namely, the depth of the ventilation slots 12 is gradually decreased from the middle of the pillow core main body 11 to two sides, so that the arc line 14 comprises a middle arc section 141, and a first arc section 142 and a second arc section 143 respectively arranged at two sides of the middle arc section 141. The curvature of the intermediate arcuate segment 142 relative to the ventilation slot 12 is positive, while the curvature of the first and second arcuate segments 142, 143 relative to the ventilation slot 12 is negative. Therefore, the pillow core main body 11 has different supporting forces on different parts of the user, namely, can provide larger supporting force on the neck of the user so as to conform to the physiological structure of the human body, and can provide smaller supporting force on the brain bag, so that the compression on blood in the brain bag is reduced, the user has a sufficient rest, and the user has better sleeping experience.

The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
