Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 This utility model provides a technical solution: a foam head pillow that is easy to adjust according to the season, including a pillow base 1. The inner side of the pillow base 1 is symmetrically provided with upper and lower grooves 11. Each groove 11 is independently provided with a head pillow component 3. The outer side of the pillow base 1 is also provided with a twisting component 2 that can drive the two sets of head pillow components 3 to move horizontally in opposite directions and complete the misalignment. The bottom of the pillow base 1 is also symmetrically provided with a density adjustment component 4 that can be pushed up to adjust the density of the head pillow components 3.

[0027] This design solves the problem of existing foamed silicone pillows requiring different external material replacement layers to be bonded to the headrest in order to adjust the breathability or warmth of the headrest according to seasonal changes, which is cumbersome and dependent on external accessories.

[0028] Please see Figure 3 The screwing assembly 2 includes a limiting frame 22, which is fixedly connected to the outside of the pillow seat 1. The screwing assembly 2 also includes a worm gear 211, which is rotatably connected to the middle of the limiting frame 22. The screwing assembly 2 also includes a screwing sleeve 21, which is fixedly connected to the top of the worm gear 211.

[0029] The screwing assembly 2 also includes a rotating shaft 23, which is rotatably connected in the slot on the side of the pillow seat 1. The screwing assembly 2 also includes a worm gear 231, which is in contact with the worm 211 and is meshed and rotatably connected.

[0030] This design allows the rotating shaft 23 to rotate within the slot on the side of the pillow seat 1, with the cooperation of the worm gear 211 and the worm wheel 231. At the same time, the self-locking capability of the worm gear 211 and the worm wheel 231 can prevent the rotating shaft 23 from becoming loose after rotating within the slot on the side of the pillow seat 1.

[0031] Please see Figure 1 The rotating assembly 2 also includes a gear 232, which is fixedly connected to the end of the rotating shaft 23 away from the worm gear 231;

[0032] The headrest assembly 3 also includes a headrest frame 31, which is slidably connected in the slide groove 11. The headrest assembly 3 also includes a toothed groove group 32, which is evenly distributed on the outside of the headrest frame 31. Both toothed groove groups 32 on the outside of the headrest frame 31 are in contact with the toothed disc 232 and are meshing transmission connected.

[0033] The headrest assembly 3 also includes a foam headrest body 33, which is fixedly connected to the upper and lower headrest frames 31 respectively, and the size of the equally spaced hollow holes in the middle of the upper and lower foam headrest bodies 33 is matched.

[0034] The rotating shaft 23 drives the toothed disc 232 to rotate inside the pillow seat 1, thereby enabling the head pillow frame 31 located on the upper and lower sides of the toothed disc 232 to move horizontally in opposite directions under the cooperation of the tooth groove group 32 and the toothed disc 232.

[0035] This design allows the hollowed-out holes in the middle of the two sets of foam headrest bodies 33 to overlap or be misaligned.

[0036] When they overlap, the perforations can be closed to reduce heat loss; when they are misaligned, ventilation channels can be formed to improve air permeability.

[0037] Please see Figure 4 and Figure 5 and Figure 6 The looseness adjustment component 4 includes a lower bracket 41, which is fixedly connected to the bottom of the inner side of the pillow seat 1, and a threaded tube 411 is fixedly connected to the middle of the lower bracket 41.

[0038] The tightness adjustment component 4 includes a threaded post 43, which is threadedly connected to the threaded tube 411. A handle 431 is fixedly connected to the bottom of the threaded post 43, and an upper plate 42 is fixedly connected to the top of the threaded post 43. The tightness adjustment component 4 also includes a slotted mesh 421, which is fixedly connected to the slotted opening around the upper plate 42.

[0039] By turning the handle 431, the threaded column 43 is driven to rotate inside the threaded tube 411, thereby enabling the upper top plate 42 and the groove mesh 421 to complete the vertical advancement work and thus compress the foamed headrest body 33 to different degrees.

[0040] Working principle:

[0041] By turning the screw sleeve 21, the worm gear 211 can be driven to rotate within the limit frame 22. With the cooperation of the worm gear 211 and the worm wheel 231, the rotating shaft 23 can drive the gear plate 232 to rotate, thereby causing the upper and lower sets of headrest frames 31 to move horizontally in opposite directions with the cooperation of the gear plate 232 and the tooth groove group 32. This design allows the hollow holes in the middle of the two sets of foamed headrest bodies 33 to overlap or be staggered.

[0042] When they overlap, the perforated holes can be closed to reduce heat loss;

[0043] When misaligned, ventilation channels can be formed to improve air permeability;

[0044] Specifically, by turning the handle 431, the threaded column 43 is driven to rotate inside the threaded tube 411, thereby enabling the upper top plate 42 and the slotted mesh 421 to complete the vertical advancement work.

[0045] When the temperature is low, the density can be increased by placing the foam headrest body 33 on the top plate 42 to reduce airflow and improve warmth retention; similarly;

[0046] When the temperature is high, the density of the foam headrest body 33 can be reduced by moving the top plate 42 downward, thereby enhancing breathability.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
