Description

Technical Field

[0001] This utility model relates to the field of pillow technology, specifically to a pillow. Background Technology

[0002] As an indispensable item for daily sleep, the height and support of pillows directly affect cervical spine health and sleep quality. In existing technology, some pillows achieve height adjustment by adding or removing filling material; that is, by increasing or decreasing the amount of filling, the pillow's support height is adjusted.

[0003] However, in existing technologies, the filling bag is mostly attached to the pillowcase, which has poor positioning and fit with the pillow core, making it easy to shift. Furthermore, the adjustment method makes it inconvenient to add or remove filling, resulting in insufficient support stability. It is difficult to accurately adapt to the cervical support needs of different people, and long-term use can easily cause cervical discomfort due to improper height. Utility Model Content

[0004] This invention provides a pillow to solve the problems mentioned in the background art.

[0005] To solve the above problems, this utility model provides a pillow, including a pillow core and an adjustment bag. The pillow core has a groove at the position for supporting the human head, and the adjustment bag is disposed in the groove. The adjustment bag is characterized in that: the adjustment bag includes: an inner sleeve, the inner sleeve has a receiving space and is provided with a first opening communicating with the receiving space, through which filling material can be put into or taken out of the receiving space.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting a groove at the head support position of the pillow core and placing the adjustment bag with an inner sleeve inside the groove, the pillow height can be easily adjusted by adding or removing filling through the first opening in the inner sleeve's accommodating space. The cooperation between the groove and the adjustment bag prevents the adjustment bag from shifting, enhancing structural stability and solving the problem of unstable support caused by the filling bag being attached to the pillowcase in existing technologies. At the same time, the first opening directly connects to the accommodating space, allowing operation without disassembling the adjustment bag, simplifying the process of adding or removing filling, and quickly adapting to the different needs of different people for head support height. This improves ease of use and support reliability, and reduces the risk of cervical discomfort caused by improper pillow height.

[0007] Furthermore, the adjustment package includes an adjustment mechanism located in the receiving space, comprising a scissor linkage assembly and a drive assembly. The drive assembly drives the scissor linkage assembly to extend and retract to adjust the height of the adjustment package, thereby adapting to the support requirements of the human head. The padding material is filled between the adjustment mechanism and the inner sleeve.

[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: The adjustment mechanism within the adjustable pillow allows for precise and continuous height adjustment by driving the scissor linkage assembly to extend and retract. This avoids the limitations of existing technologies that rely solely on adding or removing filling material to adjust height, effectively adapting to the diverse head support needs of different individuals. Simultaneously, the adjustment mechanism provides a rigid support base, working in conjunction with the filling material to form effective support. This avoids the instability caused by relying solely on filling material, ensuring stable pillow height over long-term use, reducing the risk of uneven stress on the cervical spine, and allowing for adjustment of the pillow's firmness by adding or removing filling material, thus guaranteeing a superior user experience.

[0009] Furthermore, the adjustment mechanism includes: a base plate, which has a first sliding groove, with one end of the bottom of the scissor link assembly hinged to the base plate and the other end slidably connected to the first sliding groove; and a top plate, which is arranged parallel to the base plate, and has a second sliding groove, with one end of the top of the scissor link assembly hinged to the top plate and the other end slidably connected to the second sliding groove.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the sliding groove structure of the bottom plate and the top plate provides a stable sliding trajectory for the extension and retraction of the scissor lift linkage assembly, ensuring the structural stability of the adjustment mechanism during extension and retraction, and improving the accuracy and smoothness of height adjustment.

[0011] Furthermore, the scissor lift assembly includes: a first link, which includes a first end and a second end disposed opposite to each other, the first end being hinged to the top plate and the second end being slidably connected to the first slide groove; and a second link, which includes a third end and a fourth end disposed opposite to each other, the third end being hinged to the bottom plate and the fourth end being slidably connected to the second slide groove; wherein the first link and the second link are arranged intersectingly, and the middle position of the first link and the middle position of the second link are hinged together.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By connecting the ends of the first and second connecting rods to the top and bottom plates respectively through hinges and sliding grooves, a stable scissor lift structure is formed, which makes the force on the scissor lift assembly balanced during extension and retraction, and the power transmission smooth, avoiding jamming or structural deformation. This improves the stability of height adjustment and the load-bearing capacity of the adjustment mechanism, and extends the service life.

[0013] Furthermore, the drive assembly includes: a lead screw structure mounted on the base plate; and a drive rod, which is a telescopic structure comprising a front end and a rear end disposed opposite to each other. The front end of the drive rod is hinged to the fourth end of the second connecting rod and slidably connected to the second slide groove. The rear end of the drive rod is hinged to the lead screw structure and slidably connected to the first slide groove. The lead screw structure drives the front end of the drive rod to slide along the second slide groove, thereby actuating the scissor lift assembly to extend and retract.

[0014] Compared with existing technologies, the technical effects achieved by this solution are as follows: the retractable drive rod is driven by a lead screw structure, which in turn drives the scissor lift assembly to extend and retract. The sliding engagement between the drive rod and the slide groove ensures the stability of the scissor lift assembly's extension and retraction, improves the accuracy and efficiency of height adjustment, and makes operation smoother.

[0015] Furthermore, the lead screw structure includes a motor, a lead screw, and a movable nut; the motor is mounted on the base plate, and the output end of the motor is fixedly connected to one end of the lead screw, and the lead screw is arranged parallel to the second slide groove; the movable nut is sleeved on the lead screw and threadedly engaged with the lead screw, and the movable nut is hinged to the rear end of the drive rod; wherein, when the motor drives the lead screw to rotate, the movable nut moves along the axial direction of the lead screw, thereby driving the drive rod to slide along the second slide groove.

[0016] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: the motor drives the lead screw to rotate, which in turn drives the moving nut to move axially, thereby driving the drive rod to extend and retract the scissor lift assembly, thus achieving the adjustment of the bag height.

[0017] Furthermore, the adjustment mechanism includes a remote control device, which is located outside the inner sleeve and electrically connected to the motor.

[0018] Compared with existing technologies, the technical effect achieved by adopting this technical solution is: remote control of the adjustment mechanism can be realized by connecting the inner and outer remote control devices to the motor.

[0019] Furthermore, the pillow core includes a first lateral sleeping portion and a second lateral sleeping portion, which are symmetrically arranged on both sides of the groove; both the first lateral sleeping portion and the second lateral sleeping portion have an arc-shaped transition surface that slopes towards the groove on the side closest to the groove.

[0020] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the first and second side-lying parts, which are symmetrically arranged on both sides of the groove, combined with the arc-shaped transition surface that slopes towards the groove, can conform to the curve of the shoulder and neck when lying on the side, fill the gap between the shoulder and neck, enhance the support and fit when lying on the side, and improve sleep comfort.

[0021] Furthermore, the adjustment package is adapted to the shape of the groove, and the adjustment package is detachably embedded in the groove and fits tightly against the inner wall of the groove.

[0022] Compared with existing technologies, the technical effects achieved by this solution are as follows: the adjustment package is adapted to the shape of the groove and can be detachably embedded; the tightly fitting structure prevents the adjustment package from shaking in the groove, improving the overall support stability; and the detachable design facilitates the disassembly, cleaning, replacement, or maintenance of the adjustment package.

[0023] Furthermore, the pillow includes: a pillowcase that covers the pillow core and the adjustment sleeve; the pillowcase has a second opening, and when the adjustment sleeve is in the groove, at least a portion of the second opening corresponds to the position of the first opening.

[0024] Compared with existing technologies, the technical advantages of this solution are as follows: By placing the pillowcase outside the pillow core and adjustment pack, the pillow core and adjustment pack can be integrated into a single unit, preventing relative displacement during use. Simultaneously, the pillowcase prevents dust and sweat from directly contacting the pillow core and adjustment pack, providing protection, and is easy to remove and wash, maintaining pillow hygiene. Furthermore, through a second opening on the pillowcase corresponding to the first opening on the inner cover, the filling in the inner cover can be added or removed directly through both openings without removing the pillowcase, simplifying the filling adjustment process and improving usability.

[0025] The advantages of this utility model over the prior art are as follows:

[0026] (1) By setting a groove at the head position of the pillow core and placing the adjustment sleeve with an inner sleeve in the groove, the filling material can be flexibly increased or decreased through the first opening, so as to achieve convenient adjustment of the pillow height.

[0027] (2) The adjustment mechanism provides a rigid support base, which, together with the filling, forms effective support. This avoids the problem of unstable support caused by relying solely on the filling, ensures the stability of the pillow height during long-term use, reduces the risk of uneven force on the cervical spine, and allows the softness and hardness of the pillow to be adjusted by adding or removing the filling, thus ensuring the user's experience.
