[0028] like Figures 1 to 8 As shown, an adjustable cervical pillow includes a cervical pillow body 1 and a fixed frame 2. The cervical pillow body 1 is fixedly mounted on the fixed frame 2. A first breathable plate 5 is fixedly mounted inside the fixed frame 2. Two grooves 16 are formed inside the fixed frame 2. A through groove 15 is formed inside the fixed frame 2 at the top of the grooves 16. A movable frame 3 is slidably mounted inside the fixed frame 2. Triangular plates 18 are fixedly mounted on both sides of the movable frame 3 in the two through grooves 15 respectively. Sliding grooves 11 are formed on both sides of the fixed frame 2 in the through grooves 15. Limiting blocks 14 are slidably mounted in the sliding grooves 11. One end of the limiting block 14 extends into the through groove 15, and the top of the limiting block 14 contacts the bottom of the triangular plate 18. Two springs 13 are provided in the sliding grooves 11. Two sets of drive components are provided in the fixed frame 2 for driving the corresponding two limiting blocks 14 away from each other. Figures 4 to 6 As shown, the drive assembly includes a circular groove 6, which is located inside the fixed frame 2 and on one side of the groove 16. A rectangular groove 17, which communicates with the through groove 15, is provided inside the fixed frame 2 and above the circular groove 6. A circular plate 7 is slidably installed inside the circular groove 6. A rectangular rod 8 is fixedly installed on the top of the circular plate 7. One end of the rectangular rod 8 extends through the top of the circular groove 6 into the rectangular groove 17 and is fixedly installed with a push plate 10. A tension spring 9 is sleeved on the rectangular rod 8 and inside the rectangular groove 17. The two ends of the tension spring 9 are tightly welded to the bottom of the push plate 10 and the bottom of the rectangular groove 17, respectively.

[0029] More specifically, the movable frame 3 is installed into the fixed frame 2 and pushed, causing the two triangular plates 18 to slide within their corresponding grooves 16 until they enter the through groove 15 and contact the corresponding two limiting blocks 14. At this point, the two baffles 4 will enter their corresponding grooves 16. Then, the movable frame 3 is pushed further, causing the triangular plates 18 to press the two limiting blocks 14 away from each other. The limiting blocks 14 will slide and displace on the corresponding two guide rods 12, and the spring 13 will contract under pressure until the triangular plates 18 are displaced to the top of the two limiting blocks 14. At this point, the triangular plates 18 will contact the top of the inner wall of the through groove 15. Then, under the action of the spring 13's rebound force, the spring 13 will drive the limiting blocks 14 to displace, causing the corresponding two limiting blocks 14 to enter the through groove 15. At this point, the triangular plates 18... The bottom of 8 will contact the top of the limiting block 14. The two limiting blocks 14 will limit the position of the triangular plate 18, thereby fixing the moving frame 3 in the fixed frame 2. During disassembly, the operator can press the two round plates 7 by hand. The two round plates 7 will drive the two rectangular rods 8 to move upward respectively. The two rectangular rods 8 will drive the two push plates 10 to move upward respectively. At this time, the tension spring 9 will be stretched by the tension, and the upward movement of the push plate 10 will squeeze the corresponding two limiting blocks 14 away from each other in the same way as above, until the two limiting blocks 14 enter the corresponding slide groove 11. At this time, the triangular plate 18 will be released from the fixation, and then the moving frame 3 will move downward. The moving frame 3 will drive the two triangular plates 18 to move out of the through groove 15 and the groove 16, and the baffle 4 will also move out of the corresponding groove 16.

[0030] A movable box 20 is slidably installed inside the movable frame 3, and a second ventilated plate 19 is fixedly installed inside the movable box 20.

[0031] More specifically, when using the device, staff can first remove the mobile box 20 from the mobile frame 3, then place desiccant granules at the bottom of the inner cavity of the mobile frame 3, and then place sleep-aiding Chinese medicine into the mobile box 20. Afterwards, the mobile box 20 can be placed back into the mobile frame 3. With the help of the desiccant granules, the Chinese medicine placed in the mobile box 20 can be kept dry.

[0032] like Figure 4 As shown, the rectangular rod 8 is slidably connected to the fixed frame 2 and the rectangular groove 17, and the inclined surfaces on both sides of the top of the push plate 10 are in contact with the inclined surfaces on the opposite side of the two corresponding limiting blocks 14.

[0033] More specifically, this ensures that the rectangular rod 8 can slide within the fixed frame 2 and the rectangular groove 17, and that when the push plate 10 moves upward, it can squeeze the two limiting blocks 14 away from each other.

[0034] like Figure 7As shown, baffles 4 are fixedly installed on both sides of the movable frame 3 and in the two grooves 16 respectively, and the baffles 4 are inserted into the grooves 16.

[0035] More specifically, the baffle 4 ensures that the groove 16 is more stable and prevents it from shaking.

[0036] like Figure 7 As shown, the triangular plate 18 is slidably connected to the through groove 15, and the triangular plate 18 is slidably connected to the groove 16.

[0037] More specifically, this ensures that the triangle 18 can slide within the through groove 15 and that the triangle 18 can slide within the recess 16.

[0038] like Figure 4 As shown, two guide rods 12 are fixedly installed in the slide groove 11. Two springs 13 in the slide groove 11 are respectively sleeved on the two guide rods 12. The two ends of the springs 13 are tightly welded to the other end of the limiting block 14 and the inner wall of the slide groove 11, respectively. One end of the guide rod 12 extends into the limiting block 14, and the limiting block 14 is slidably connected to the guide rod 12.

[0039] More specifically, this ensures that the limiting block 14 can slide on the corresponding two guide rods 12, thereby ensuring the stability of the displacement of the limiting block 14 and the structural stability of the spring 13.

[0040] In summary: During use, the operator can first remove the movable box 20 from the movable frame 3, then place desiccant granules at the bottom of the inner cavity of the movable frame 3, and then place sleep-aiding traditional Chinese medicine into the movable box 20. Afterwards, the movable box 20 can be placed back into the movable frame 3, and then the movable frame 3 can be installed into the fixed frame 2 and pushed, causing the two triangular plates 18 to slide within their corresponding grooves 16 until the triangular plates 18 enter the through groove 15 and contact the corresponding two limiting blocks 14. At this point, the two baffles 4 will enter their corresponding grooves 16. Then, by continuing to push the movable frame 3, the triangular plates 18 will press against the two... The limiting blocks 14 are far apart from each other. The limiting blocks 14 will slide and move on the corresponding two guide rods 12. The spring 13 will be compressed and contracted until the triangular plate 18 is moved to the top of the two limiting blocks 14. At this time, the triangular plate 18 will contact the top of the inner wall of the through groove 15. Then, under the action of the spring 13's rebound force, the spring 13 will drive the limiting blocks 14 to move, so that the corresponding two limiting blocks 14 enter the through groove 15. At this time, the bottom of the triangular plate 18 will contact the top of the limiting block 14. The two limiting blocks 14 will limit the position of the triangular plate 18, so that the moving frame 3 is fixed in the fixed frame 2.

[0041] During disassembly, workers can press the two circular plates 7 by hand. The two circular plates 7 will drive the two rectangular rods 8 to move upward, and the two rectangular rods 8 will drive the two push plates 10 to move upward. At this time, the tension spring 9 will be stretched due to the tension, and the upward movement of the push plates 10 will squeeze the corresponding two limiting blocks 14 away from each other in the same way as described above, until the two limiting blocks 14 enter the corresponding slide groove 11. At this time, the triangular plate 18 will be released from the fixation, and then the moving frame 3 will move downward. The moving frame 3 will drive the two triangular plates 18 to move out of the through groove 15 and the groove 16, and the baffle 4 will also move out of the corresponding groove 16.
