[0018] Reference Figures 1 to 4 This utility model discloses a height-adjustable pillow, comprising an air bladder 1, a mounting base 6 fixedly connected to the side surface of the air bladder 1, a mounting groove 9 formed on the side surface of the mounting base 6, a through hole formed on the inner side wall of the mounting groove 9 near the center, a rubber ring 19 fixedly connected to the mounting groove 9 near the through hole, the mounting groove 9 being cross-shaped, a spring 11 fixedly connected to the inner side surface of the mounting groove 9, a limit block 10 fixedly connected to one end of the spring 11, a connector 12 fixedly connected to the side surface of the limit block 10, a telescopic column fixedly connected to the inner side wall of the mounting groove 9 near the spring 11, one end of the telescopic column being fixedly connected to the outer arc surface of the limit block 10, a sliding block 15 slidably connected to the inner side surface of the mounting groove 9 away from the spring 11, a pressing block 13 fixedly connected to the side surface of the sliding block 15, a connecting plate 14 fixedly connected to the side surface of the pressing block 13, a connecting end 16 provided near the through hole of the mounting groove 9, and the limit block 10 being curved. The main body 2 has embedded electronic components for controlling the operation of the massage layer 8, which can activate the massage function when needed.

[0019] The upper surface of the airbag 1 is fixedly connected to the main body 2, and the inside of the main body 2 is fixedly connected to the arch frame 18. The end of the connecting tube 5 away from the connecting end 16 is fixedly connected to the inflatable ball 4. The side surface of the inflatable ball 4 is fixedly connected to the Velcro closure 1, and the connecting end 16 is fixedly connected to the connecting tube 5. There are multiple connecting parts 12. The Velcro closure closure 2 set in the positioning groove 17 has a hook side, while the Velcro closure closure 1 on the surface has a rough side. In this way, after use, the inflatable ball 4 can be stored and placed in the positioning groove 17 by their mutual cooperation.

[0020] An anti-slip pad 3 is fixedly connected to the lower surface of airbag 1, and a label 7 is fixedly connected to the side surface of airbag 1. A positioning groove 17 is opened on the side surface of the main body 2 near the mounting base 6. A Velcro strap 2 is fixedly connected to the inner surface of the positioning groove 17. One end of each side of the compression block 13 is beveled, and a massage layer 8 is provided on the upper surface of the main body 2. The surface of the connecting end 16 is made of rubber, which can cooperate with the rubber ring 19 to achieve a certain degree of sealing effect. The connecting tube 5 is made of soft silicone.

[0021] Working principle: During use, first remove the inflatable rubber ball 4 from the positioning groove 17, and simultaneously separate the Velcro 1 and Velcro 2. Next, by pressing the inflatable rubber ball 4, air is inflated into the airbag 1 via the connecting end 16 and connecting tube 5, thereby adjusting the height of the main body 2 to meet different user needs. When the inflatable rubber ball 4, connecting end 16, and connecting tube 5 show damage or cracks, they need to be replaced or maintained. Specific operating steps are as follows: Push multiple connecting plates 14, causing the connecting plates 14 to move the extrusion block 13 towards the connector 12. During this process, the inclined surface of the extrusion block 13 will press against the inclined surface of the connector 12, causing the limiting blocks 10 to move away from each other, while the spring 11 is compressed. At this point, one end of the connecting end 16 can be easily removed from the insertion hole, thus completing the disassembly of the connecting end 16, connecting tube 5, and inflatable rubber ball 4. After maintenance, if a new connecting end 16, connecting tube 5, and inflatable rubber ball 4 need to be installed, the following steps can be followed: Insert one end of the new connecting end 16 into the socket, ensuring that its surface is tightly fitted with the edge of the rubber ring 19. Then release the connecting plate 14, causing the compression blocks 13 to move closer together, which in turn causes the limiting block 10 to lock the concave surface of the connecting end 16, thereby achieving limiting and fixing, and completing the entire installation process.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
