[0002] As people's quality of life improves, more and more people begin to pay attention to the quality of sleep, and pillows are an important factor in sleep quality. In order to meet the needs of different users for head support height and make pillows more ergonomic, people have designed pillows with different hardness and heights, including pillows with a layered structure design.

[0003] Although these pillows with a layered design have different heights at both ends, they only provide two head support height options, which limits the pillow's ability to meet the different users' requirements for pillow support height. In addition, different users have different requirements for pillow softness and hardness. Among the existing pillows with a layered structure design, the method for adjusting the softness and hardness of the pillow is mostly achieved by changing the density of the pillow material, and most of them are achieved by gradually changing the material density from the middle to the outside. The method for adjusting the softness and hardness of the pillow is single and the range of softness and hardness options is limited. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model discloses a double-layer combined pillow core with adjustable height and hardness. Figures 1 to 5 As shown in combination, the pillow core 12 includes an upper support body 1 and a lower support body 2. The bottom of the upper support body 1 is provided with a matching groove 3, and the lower support body 2 is matched in the bottom end of the upper support body 1 through the matching groove 3. The front and rear ends of the matching groove 3 are provided with a first recessed portion 4. The recessed degrees of the first recessed portions 4 at the front and rear ends of the matching groove 3 are different. The front and rear ends of the top of the lower support body 2 are respectively provided with a first protrusion 5 and a second protrusion 6 that are matched in the first recessed portion 4. The height of the first protrusion 5 is different from that of the second protrusion 6. The middle part of the upper support body 1 is provided with a second recessed portion 7. The surface of the upper support body 1 outside the left and right sides of the second recessed portion 7 is provided with a groove body 8 leading to the left and right end faces of the upper support body 1. After the upper support body 1 and the lower support body 2 are matched, the groove body 8 forms an exhaust channel 9 located in the middle of the pillow core 12.

[0021] It should be noted that: the upper support body 1 is mated to the lower support body 2 along the direction of the mating groove 3 and the top of the lower support body 2, so that the upper support body 1 and the lower support body 2 form a whole, and then the pillow core 12 is formed; assuming that the pillow core 12 is in the initial state at this time, the first protrusion 5 is mated in the first recessed portion 4 at the front end of the mating groove 3, and the second protrusion 6 is mated in the first recessed portion 4 at the rear end of the mating groove 3, and since the height of the first protrusion 5 is different from that of the second protrusion 6, the heights of the front and rear ends of the pillow core 12 are also different. Therefore, the front and rear ends of the pillow core 12 can provide two heights for supporting the user's head during sleep.

[0022] Secondly, when the upper support body 1 is turned over the lower support body 2 in the mating direction, the second protrusion 6 is mated in the first recessed portion 4 at the front end of the mating groove 3, and the first protrusion 5 is mated in the first recessed portion 4 at the rear end of the mating groove 3. In addition, the degree of depression of the first recessed portion 4 at the front and rear ends of the mating groove 3 is different. Therefore, the heights of the front and rear ends of the newly assembled pillow core 12 are different, and the heights of the front and rear ends are also different compared to the initial state. The front and rear ends of the pillow core 12 can provide two other heights for supporting the user's head during sleep.

[0023] Moreover, after the upper support body 1 is rotated in the direction of cooperation above the lower support body 2, the thickness of the front and rear ends of the pillow core 12 will also change accordingly. The thickness of the pillow core 12 has a certain influence on the support effect on the user's head, so the hardness of the pillow core 12 can be adjusted; the pillow core 12 formed by the combination of the upper support body 1 and the lower support body 2, with the setting of the second recessed portion 7 and the groove body 8 in the upper support body 1, the thickness of the pillow core 12 at the position where the second recessed portion 7 and the groove body 8 are located will change, thereby changing the hardness of the pillow core 12 at the position where the second recessed portion 7 and the groove body 8 are located.

[0024] In addition, the exhaust channel 9 can be used to quickly exhaust the interior of the pillow core 12, so that the pillow core 12 can be quickly deformed and the shape of the pillow core 12 can fit the contours of the human cervical spine and head.

[0025] The pillow core 12 can not only adjust different surface heights to meet the head placement height requirements of different users when sleeping, but also adjust the softness and hardness of the pillow core 12 by changing the thickness of the pillow core 12, so that the pillow 10 with the pillow core 12 can meet the softness and hardness requirements of different users.

[0026] It needs to be further explained that, Figure 5 As shown, the exhaust passage 9 is formed by the groove body 8 on the left side of the upper support body 1, the groove body 8 on the right side and the second recessed portion 7 being connected.

[0027] During use, when the user's head is located in the middle of the top surface of the pillow core 12, the position of the pillow core 12 where the second recessed portion 7 is located will be recessed downward, and the air in the middle position of the pillow core 12 will be discharged from the groove body 8 on the left and right sides of the support body to the outside of the pillow core 12, respectively, so that the pillow core 12 can be deformed quickly and the shape of the pillow core 12 fits the contours of the human cervical spine and head.

[0028] It needs to be further explained that, Figure 2 and Figure 4 As shown in the figure, the top surface heights of the front and rear ends of the upper support body 1 are different.

[0029] Due to the different top surface heights of the front and rear ends of the upper support body 1, the heights of the front and rear ends of the support body are different. At the same time, due to the different degrees of depression of the first recessed portion 4 and the different top surface heights of the first protruding portion 5 and the second protruding portion 6, the top surface heights of the front and rear ends of the upper support body 1 are at the same height position after the pillow core 12 is assembled. The front and rear ends of the pillow core 12 are the same height, providing additional height to meet the user's head and neck support needs during sleep.

[0030] It should be further explained that the hardness of the left and right parts of the upper support body 1 is different from each other, and the hardness of the lower support body 2 is greater than that of the upper support body 1 .

[0031] Among them, the user can choose the left part or the right part of the upper support body 1 to support the head and neck according to his or her own requirements for the hardness of the pillow core 12 for supporting the head and neck, so that the hardness of the pillow core 12 can meet the usage needs of different users; and the hardness of the lower support body 2 is greater than that of the upper support body 1, which can make the pillow core 12 have a stronger ability to maintain the shape of the lower support body 2 when in use, so as to avoid the situation where the matching position of the upper support body 1 above the lower support body 2 is offset after both the upper support body 1 and the lower support body 2 are deformed.

[0032] The utility model also discloses a pillow, as shown in FIG. Figure 6 and Figure 7 As shown, it includes a pillowcase 11 and the pillow core 12 , wherein the pillow core 12 is fitted in the pillowcase 11 , and an air nozzle 13 is provided on the surface of the pillowcase 11 , and the air nozzle 13 is connected to a sealing plug 14 .

[0033] It should be noted that the pillowcase 11 of the pillow 10 is not airtight as a whole. When the height and size of the pillow 10 need to be lowered, the sealing plug 14 can be pulled out from the air nozzle 13, and the volume of the pillow 10 can be compressed by pressing the pillow 10. After being compressed to the required size, the sealing plug 14 can be inserted into the air nozzle 13 to seal the air nozzle 13. The air outside the pillow 10 cannot enter the pillow 10, and the compressed pillowcase 11 and pillow core 12 cannot expand again, so that the shape of the pillow 10 can be maintained. When the pillow 10 needs to be restored to its original shape, the sealing plug 14 in the air nozzle 13 can be pulled out to allow the air outside the pillow 10 to enter the pillow 10 to expand the pillow 10, thereby achieving the purpose of adjusting the height and size of the pillow 10 and further expanding the scope of application of the pillow 10.

[0034] It needs to be further explained that, Figure 6 and Figure 7 As shown in the figure, the air nozzle 13 is arranged on the surface of the pillowcase 11 outside the exhaust channel 9.

[0035] During the use of the pillow 10, since exhaust channels 9 are provided on both sides of the pillow 10 and an air nozzle 13 is provided on the outside of the exhaust channel 9, the shape of the pillow 10 will not change when the pillow 10 is used without pulling out the sealing plug 14 in the air nozzle 13. However, the shape of the pillow 10 will change when the pillow 10 is used with the sealing plug 14 in the air nozzle 13 pulled out. The above two methods can enrich the usage of the pillow 10 and further expand the scope of application of the pillow 10.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
