[0002] Existing head pressure relief pillows are generally ordinary cotton pillows. Because they only use a simple soft structure, they are easy to compress brain tissue and cause symptoms of skull defect syndrome such as dizziness, headache, and irritability.

[0003] For example, a neurosurgery head decompression pillow disclosed in announcement number CN216021799U is provided with ear grooves to prevent the patient's ears from being squeezed, making the patient's ears more comfortable and convenient for the patient to use the pillow for a long time and use an eye mask to facilitate the patient to rest and relieve stress. However, it can only provide support for the head, while the neck and other parts of the body are in a suspended state. After a long sleep, the soreness of the suspended parts will be aggravated. Existing pillows pursue a single softness, so the head is very likely to move in position and angle from the pillow during unconscious sleep, and it is impossible to ensure that the head fits the shape of the pillow, which will result in the inability to provide comfortable support for the head, seriously affecting the sleep quality.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 A pillow that is convenient for fixing the head includes a main frame 1, on which are opened a limiting beam groove 2 and a supporting groove 3 corresponding to the neck and head respectively. A rubber cover and a cloth cover supported by fiber cloth are put on the main frame 1. It should be noted that the limiting beam groove 2 is connected with the supporting groove 3 and is used to place the neck and head.

[0024] The front end of the main frame 1 is provided with a corresponding limit beam slot 2 and a soothing mechanism for massaging the neck. Figure 3 The soothing mechanism includes a water storage chamber 4 and an impact chamber 5 opened at the front end of the main frame 1. A water inlet 6 is provided at the upper end of the main frame 1, which is connected to the water storage chamber 4 and the impact chamber 5 in a one-way manner from top to bottom, and a return water port 7 is provided at the lower end of the main frame 1, which is connected to the impact chamber 5 and the water storage chamber 4 in a one-way manner from bottom to top. Under the action of gravity, the water in the initial state is located in the water storage chamber 4. Under the pressure of the neck and head, the water in the water storage chamber 4 flows into the impact chamber 5 in a one-way manner through the water inlet 6 to impact the limiting beam groove 2, thereby forming a massage effect. The water entering the impact chamber 5 enters the water storage chamber 4 again through the return water port 7 for reuse. A replacement port connected to the water storage chamber 4 is provided in the main frame 1 to replenish or replace the water.

[0025] The rear end of the main frame 1 is provided with an oblique cavity 8, a hollow cavity 9 and a bottom cavity 10 corresponding to the support groove 3, and the main frame 1 is provided with a limit mechanism for symmetrically supporting the head through the oblique cavity 8, the hollow cavity 9 and the bottom cavity 10. For details, please refer to the attached manual. Figure 4 With attached Figure 5The limiting mechanism includes a three-way tube 11 fixedly installed in the bottom cavity 10 and the hollow cavity 9, a driving piston 12 is threadedly installed in the lower end opening of the three-way tube 11, and a driven piston 13 is slidably sleeved in the upper end opening of the three-way tube 11, and the three-way tube 11 is filled with inert gas or hydraulic oil between the driving piston 12 and the driven piston 13 to realize the linkage between the driving piston 12 and the driven piston 13, and a telescopic rod 14 extending to the oblique cavity 8 is slidably sleeved in the hollow cavity 9, and a support plate 15 and a support rod 16 are fixedly installed on both ends of the telescopic rod 14, respectively. A traction link 17 is movably connected between the driven piston 13 and the support plate 15, and a support roller 19 that movably contacts the support groove 3 is fixedly installed on the support rod 16. By driving the support roller 19 to retract and retract in the oblique cavity 8, the support roller 19 can squeeze the support groove 3 at different positions, thereby limiting the support of the head located in the support groove 3.

[0026] The limiting beam groove 2 and the supporting groove 3 are opened from front to back at the top of the main frame 1 to provide a placement position and support for the neck and head.

[0027] The water storage chamber 4 and the impact chamber 5 are distributed from bottom to top below the limiting beam groove 2. Under the action of gravity and pressure, the water body is driven to flow, forming a water flow to perform dynamic massage on the neck.

[0028] The support plate 15 is installed on the bottom end of the telescopic rod 14 located in the hollow cavity 9, and the traction connecting rod 17 is pin-connected to the driven piston 13 and the support plate 15. The support rod 16 is installed on the top end of the telescopic rod 14 located in the oblique cavity 8. Under the joint action of the driven piston 13 and the strong spring 18, the support roller 19 is adjusted in position in the oblique cavity 8.

[0029] A strong spring 18 sleeved on the telescopic rod 14 is fixedly installed between the support plate 15 and the inner wall of the hollow cavity 9 .

[0030] It should be noted that the specific model and specifications of the main frame 1 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0031] The functional principle of this utility model can be explained through the following operation modes:

[0032] The neck in the limiting beam groove 2 applies pressure to the main frame 1, so that the water in the water storage chamber 4 enters the impact chamber 5 through the water inlet 6, squeezing the limiting beam groove 2, thereby massaging the neck. The water in the impact chamber 5 enters the water storage chamber 4 again through the return water port 7 for reuse.

[0033] The driving piston 12 is screwed in the bottom cavity 10, and the driving piston 12 causes the driven piston 13 to telescopically move along the tee pipe 11. The driven piston 13 squeezes the support plate 15 through the traction connecting rod 17, so that the telescopic rod 14 reciprocates and telescopes between the oblique cavity 8 and the hollow cavity 9, thereby using the support roller 19 to support the head located in the support groove 3.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
