Description

Technical Field

[0001] This invention relates to the field of pillow technology, and in particular to a height-adjustable neck-protecting health pillow. Background Technology

[0002] Pillows are an important piece of bedding for ensuring sleep quality in daily life. The height requirements of pillows differ between sleeping on your back and sleeping on your side: when sleeping on your back, the curvature of the cervical spine is smaller, requiring a lower pillow to support the neck; while when sleeping on your side, the shoulder width increases, requiring a higher pillow to fill the gap between the neck and the bed surface to maintain the natural straightness of the cervical spine.

[0003] However, most pillows on the market currently have the following problems: Traditional pillows have a fixed height, which cannot meet the different height needs of sleeping on your back and side at the same time. When sleeping on your side with a low pillow, the cervical spine will bend to one side and be suspended in the air; when sleeping on your back with a high pillow, the cervical spine will be excessively flexed forward. Long-term use can easily lead to cervical strain, muscle soreness, and even cervical spondylosis.

[0004] Some existing height-adjustable pillows use manual inflation, adding or removing pads, or knob adjustments, requiring users to wake up and manually operate them when changing sleeping positions at night, which seriously affects the continuity and quality of sleep.

[0005] While some mechanically adjustable pillows can achieve height changes, their complex structures prevent them from automatically and accurately resetting to a "low position when lying on your back, high position when lying on your side, and low position when lying on your back" cycle based on the movement of the head. As a result, they are not very practical. Therefore, a neck-protecting health pillow with height resetting function is proposed. Summary of the Invention

[0006] In view of this, embodiments of the present invention provide a height-adjustable neck support health pillow to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this invention is implemented as follows: a height-resetting neck support pillow includes a pillow base plate, a cylindrical body fixedly connected to the upper surface of the pillow base plate, a hollow cylindrical support member slidably connected to the inner wall of the cylindrical body, a pillow panel fixedly connected to the upper surface of the hollow cylindrical support member, a first staggered tooth guide tube and a second staggered tooth guide tube sequentially fixedly connected to the inner wall of the cylindrical body, the first staggered tooth guide tube and the second staggered tooth guide tube being arranged opposite to each other, a rotating support plate rotatably connected to the lower surface of the hollow cylindrical support member via a bearing, protruding keys uniformly fixedly connected to the outer wall of the rotating support plate, the protruding keys engaging with the first staggered tooth guide tube and the second staggered tooth guide tube, and a spring fixedly connected to the upper surface of the pillow base plate, the top end of the spring rotatably connected to the lower surface of the rotating support plate via a bearing.

[0008] In some embodiments, the upper surface of the first staggered tooth guide tube is provided with a third inclined slot, an inclined portion and a first inclined slot in a sequential annular array, and the lower surface of the second staggered tooth guide tube is provided with a second inclined slot in a sequential annular array. A plurality of protruding keys are all in contact with the second inclined slot, the third inclined slot, the inclined portion and the first inclined slot.

[0009] In some embodiments, the outer wall of the hollow cylindrical support is uniformly provided with grooves, and the inner wall of the cylinder is uniformly fixedly connected with sliders, the outer wall of the sliders being slidably connected to the inner wall of the grooves.

[0010] In some embodiments, the outer wall of the cylinder is uniformly provided with fixing holes, the outer walls of the first staggered tooth guide tube and the second staggered tooth guide tube are attached to the inner wall of the cylinder, the outer wall of the second staggered tooth guide tube is uniformly provided with a first threaded through hole, the inner wall of the first threaded through hole is threadedly connected with a first fastening screw, and the first fastening screw passes through the corresponding fixing hole.

[0011] In some embodiments, the outer wall of the first staggered tooth guide tube is uniformly provided with a second threaded through hole, and the inner wall of the second threaded through hole is threaded with a second fastening screw, which passes through the corresponding fixing hole.

[0012] In some embodiments, the outer wall of the pillow panel is provided with a flexible layer.

[0013] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention achieves automatic pillow height adjustment based on sleeping posture by using a toothed guide tube, a rotating support plate, and a combination of a convex key and a spring. When sleeping on your back, the head presses down on the pillow panel, the convex key engages in the first inclined slot, the spring is compressed, and the pillow remains in a low position. When turning to sleep on your side and raising your head, the spring releases pressure, pushing the pillow panel upward, and the convex key is limited by the second inclined slot. When the head presses down again, the convex key engages in the third inclined slot, and the pillow is locked in a high position. This process is completed automatically based on changes in head weight, without manual intervention, perfectly meeting the ergonomic needs of sleeping on your back with a low pillow and sleeping on your side with a high pillow, effectively protecting cervical spine health.

[0014] Second, this invention achieves automatic cyclic reset of high and low positions through the special design of the staggered tooth guide structure. When turning from side sleeping (high position) to back sleeping, the head is raised and the spring pushes up to move the convex key to the next second inclined slot limit. When the head relaxes and presses down, the convex key moves along the inclined part to the next first inclined slot, and the pillow automatically resets to the low position. The adjustment logic is clear, and the high and low reset is accurate and reliable, ensuring seamless connection and continuous support when turning over at night.

[0015] Third, by opening a groove on the outer wall of the hollow cylindrical support and setting a slider on the inner wall of the cylinder, the present invention improves the stability of the lifting structure. The slider slides in the groove, which not only assists the hollow cylindrical support to move smoothly up and down, but also restricts the rotation of the hollow cylindrical support, ensuring that the convex key and each inclined slot are accurately aligned, avoiding jamming or offset, and extending the service life of the mechanism.

[0016] Fourth, the present invention makes the internal toothed guide tube detachable by the cooperation of the fastening screw and the fixing hole, which is convenient for maintenance. The first toothed guide tube and the second toothed guide tube are fixed in the cylinder by the fastening screw. When the internal components are worn or different specifications of guide tubes need to be replaced to change the lifting stroke, the screw can be unscrewed to remove and replace them. The maintenance is convenient and reduces the maintenance cost of long-term use.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1-6As shown, this embodiment of the invention provides a height-reset neck support pillow, including a pillow base plate 1, a cylindrical body 2 fixedly connected to the upper surface of the pillow base plate 1, a hollow cylindrical support 3 slidably connected to the inner wall of the cylindrical body 2, a pillow panel 4 fixedly connected to the upper surface of the hollow cylindrical support 3, a first staggered tooth guide tube 7 and a second staggered tooth guide tube 11 sequentially fixedly connected to the inner wall of the cylindrical body 2, the first staggered tooth guide tube 7 and the second staggered tooth guide tube 11 being arranged opposite to each other, a rotating support plate 5 rotatably connected to the lower surface of the hollow cylindrical support 3 via a bearing, a protruding key 10 uniformly fixedly connected to the outer wall of the rotating support plate 5, the protruding key 10 engaging with the first staggered tooth guide tube 7 and the second staggered tooth guide tube 11, a spring 6 fixedly connected to the upper surface of the pillow base plate 1, the top end of the spring 6 rotatably connected to the lower surface of the rotating support plate 5 via a bearing.

[0026] In this embodiment, specifically, the upper surface of the first staggered tooth guide tube 7 is provided with a third inclined slot 20, an inclined portion 8, and a first inclined slot 9 arranged in a ring array. The lower surface of the second staggered tooth guide tube 11 is provided with a second inclined slot 12 arranged in a ring array. Several protruding keys 10 are all in contact with the second inclined slot 12, the third inclined slot 20, the inclined portion 8, and the first inclined slot 9. With the above arrangement, when the weight of the head presses down on the pillow panel 4, the pillow panel 4 moves downward through the hollow cylindrical support member 3, causing the rotating support plate 5 to move downward. The rotating support plate 5 moves the protruding keys 10 to the first inclined slot 9. At this time, the rotating support plate 5 compresses the spring. When the head is turned to the side, the spring 6 deforms and lifts off the pillow panel 4. The spring 6 releases pressure and moves the rotating support plate 5 upward. The rotating support plate 5 simultaneously moves the convex key 10 and the hollow cylindrical support 3 upward. The hollow cylindrical support 3 moves the pillow panel 4 upward. At this time, the convex key 10 is assisted in moving and limiting its movement through the second inclined slot 12. When the head is turned to a suitable position, the weight is then transferred to the pillow panel 4 for support. The pillow panel 4 moves the rotating support plate 5 downward through the hollow cylindrical support 3. The rotating support plate 5 moves the convex key 10 to the third inclined slot 20. At this time, the adjustment of the pillow panel 4 from low to high is achieved.

[0027] In this embodiment, specifically, the outer wall of the hollow cylindrical support 3 is uniformly provided with sliding grooves 16, and the inner wall of the cylinder 2 is uniformly fixedly connected with sliders 17. The outer wall of the slider 17 is slidably connected to the inner wall of the sliding groove 16. By setting the slider 17 in the sliding groove 16, it can not only assist the hollow cylindrical support 3 to move up and down, but also stabilize the position of the hollow cylindrical support 3.

[0028] In this embodiment, specifically, the outer wall of the cylinder 2 is uniformly provided with fixing holes 14, the outer walls of the first staggered tooth guide tube 7 and the second staggered tooth guide tube 11 are attached to the inner wall of the cylinder 2, the outer wall of the second staggered tooth guide tube 11 is uniformly provided with first threaded through holes 13, the inner wall of the first threaded through hole 13 is threaded with a first fastening screw 15, the first fastening screw 15 passes through the corresponding fixing hole 14, and by the above arrangement, the first fastening screw 15 rotates through the fixing hole 14 into the first threaded through hole 13, thereby fixing the second staggered tooth guide tube 11 in the cylinder 2, and then the first fastening screw 15 is turned out from the first threaded through hole 13, so that the second staggered tooth guide tube 11 can be taken out from the cylinder 2 for easy replacement and maintenance.

[0029] In this embodiment, specifically, the outer wall of the first staggered tooth guide tube 7 is uniformly provided with second threaded through holes 18, and the inner wall of the second threaded through hole 18 is threaded with a second fastening screw 19. The second fastening screw 19 passes through the corresponding fixing hole 14. By the above arrangement, the second fastening screw 19 rotates through the fixing hole 14 into the second threaded through hole 18, thereby fixing the first staggered tooth guide tube 7 in the cylinder 2. Then, the second fastening screw 19 is turned out from the second threaded through hole 18, making it easy to remove the first staggered tooth guide tube 7 from the cylinder 2 for replacement and maintenance.

[0030] In this embodiment, specifically, the outer wall of the pillow panel 4 is provided with a flexible layer (not shown in the figure), which is used to improve the comfort of using the pillow panel 4.

[0031] When the invention is in operation: When a person sleeps on their back, the weight of their head presses down on the pillow panel 4. The pillow panel 4 moves downward through the hollow cylindrical support 3, causing the rotating support plate 5 to move downward. The rotating support plate 5 moves the protruding key 10 to the first inclined slot 9. At this time, the rotating support plate 5 compresses the spring 6, causing deformation. When the person turns to their side, their head lifts off the pillow panel 4, the spring 6 releases pressure, and the rotating support plate 5 moves upward. The rotating support plate 5 simultaneously moves the protruding key 10 and the hollow cylindrical support 3 upward. The hollow cylindrical support 3 moves the pillow panel 4 upward. At this time, the protruding key 10 is assisted in moving and limiting its position through the second inclined slot 12. When the head is turned to a suitable position, and the weight is then supported by the pillow panel 4, the pillow panel 4 moves downward through the hollow cylindrical support 3, causing the rotating support plate 5 to move downward. The rotating support plate 5 moves the protruding key 10 to the third inclined slot 20. At this time, the adjustment of the pillow panel 4 from low to high is achieved.

[0032] When changing from a side-sleeping position to a back-sleeping position, the head is lifted off the pillow panel 4 again. The elastic force of the spring 6 moves the rotating support plate 5 upward. The rotating support plate 5 simultaneously moves the convex key 10 and the hollow cylindrical support 3 upward. The hollow cylindrical support 3 moves the pillow panel 4 upward. The convex key 10 moves to the next second inclined slot 12 for movement limit. After the back-sleeping position is adjusted, the head relaxes, and the weight is returned to the pillow panel 4. The pillow panel 4 moves the rotating support plate 5 downward through the hollow cylindrical support 3. The rotating support plate 5 moves the convex key 10 to the next first inclined slot 9 with the assistance of the inclined part 8. At this time, the rotating support plate 5 compresses the spring 6 to deform, thus fixing the lower limit height of the pillow panel 4. Therefore, the pillow panel 4 can be adjusted from high to low.

[0033] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
