[0037] Referring to Figures 1 to 5 , the multi-directional air bag cervical traction instrument includes a pillow body 1, a seat body 2, and an air bag column 3 for supporting the pillow body; the pillow body 1 and the seat body 2 are provided with three or more groups of air bag columns 3 surrounding a polygon, four groups of air bag columns 3 are shown in the figure, surrounding a quadrilateral, and the pillow body 1 is suspended and supported by the air bag columns 3; the air bag columns 3 are respectively connected with the air pump 5 through the electromagnetic valves 4, and the electromagnetic valves 4 are controlled by the electric control board 8 to control the inflation and deflation of the air bag columns 3, to drive the pillow body 1 to ascend and descend and swing.

[0038] The air pump 5 is preferably designed externally, connected with the electromagnetic valve 4 arranged on the seat body 2 through the air pipe 51, and the electric control board 8 is arranged on the inner recess area formed by the seat body 2. The charging port 23, air nozzle 24, power switch 25 and external plug-in port 26 of the medium and low frequency pulse are arranged on the side of the seat body. The charging port 23 provides the need of battery charging, and the air nozzle 24 is in communication with the air pipe 51, which can be a fixed structure or designed as a plug-in structure for convenient disassembly and storage. The external plug-in port 26 provides external expansion to meet the external medium and low frequency pulse physiotherapy. Further, the air pipe 51 adopts a flexible composite cable, and the air pipe 51 is a hollow structure with independent air pipe channels and control line 52 channels, electrically connected with the electric control board 8 and the air pump 5 to control the operation of the air pump 5. In this example, the air pump 5 is arranged in a noise reduction box 53, and a wireless remote controller 83 is also positioned on the surface of the noise reduction box 53. The remote controller 83 is placed on the surface of the noise reduction box by magnetic attraction, and the remote controller 83 can also be removed for convenient remote control operation. Of course, the remote controller 83 can also be directly arranged on the side of the seat body 2, or control panels are arranged at both places.

[0039] Further, the oscillating support 6 is arranged between the middle part of the pillow body 1 and the seat body 2, and the pillow body 1 can swing around the oscillating support 6 as the pivot under the drive of the air bag column 3. That is, the height of the oscillating support 6 is between the height of the air bag column 3 when not inflated and the height when inflated. The oscillating support 6 is located at the center of the multiple groups of air bag columns 3, providing a height limit and a swing pivot, so that the pillow body 1 is lifted on one side and forced to drop on the other side under the drive of the air bag column 3, and the pillow body 1 can not only generate upward traction, but also generate backward traction. By changing the length of the oscillating support 6, the height of the pillow body 1 can be changed to meet the needs of neck physiotherapy.

[0040] The air bag column 3 is preferably four groups, symmetrically distributed in a quadrilateral on both sides of the central axis of the pillow body 1, and each side has two groups of air bag columns 3 for support, so that the pillow body 1 can obtain more stable support. Each group is composed of one to three air bag columns 3 arranged side by side, and the air bag columns 3 in the same group are in communication with each other. The air bag column 3 contains one to multiple air bag bodies 31 stacked together. In this example, only one air bag column 3 is arranged in each group, and the quadrilateral is a regular quadrilateral, an isosceles trapezoid, or a rhombus. In the rhombus, one diagonal line overlaps with the central axis of the pillow body, although the support stability is poorer than the quadrilateral, but the drive of forward and backward swing is more flexible. Only the single air bag column 3 needs to be inflated, and the rest needs to be deflated.

[0041] Further, the pillow body 1 and the seat body 2 are both plastic formed shells, the pillow body 1 is internally provided with a support plate 11; the seat body 2 is larger than the pillow body 1, and an upper portion is provided with a cover 21, the cover 21 is formed with a sunken area 211 larger than the projected area corresponding to the projected area of the pillow body 1, and the outer edge is an arched edge 212. The support plate 11 and the sunken area 211 of the cover provide abutment for the air bag column 3 and the swing pillar 6 at both ends. More specifically, the sunken area 211 is formed with a through hole 213 for the air bag inflation and deflation nozzle 311 to access corresponding to the projected position of the air bag column 3, and has a ball head seat 214 in the center position for positioning the swing pillar 6; the ball head seat 214 is a half mold structure, locked on the lower surface of the cover 21. If space permits, the ball head seat 214 can also be directly locked on the upper surface of the cover 21. Alternatively, the swing pillar 6 is arranged on one side of the sunken area 211, and the top ball head abuts in the ball head seat on one side of the support plate 11, which can also achieve the same function as the above structure.

[0042] The support plate 11 and the sunken area 211 of the cover are in parallel state, so that the ends of the plurality of air bag columns 3 can be abutted, for this purpose, the support plate 11 is formed with an upward arched positioning groove 111 corresponding to the position of the air bag column, and a positioning hole 112 is formed in the center of the positioning groove 111; the top of the air bag column 3 is provided with a positioning expansion nail 312, which passes through the positioning hole 112 to form the positioning of the top of the air bag column 3, avoiding the movement of the air bag column 3.

[0043] The swing pillar 6 has a ball head 61 and a screw segment 62, the ball head 61 is movably positioned in the ball head seat 214, and the screw segment 62 passes through the support plate 11 and is provided with a limiting nut 63 at the end. The screw segment 62 has a fixed relationship with the support plate 11. It can also be a sliding relationship. The fixed relationship is more sensitive when the air bag column 3 is driven, while the sliding relationship allows the pillow body 1 to have a lifting space without affecting the swing, meeting different height requirements, and a spring can be provided on the screw segment when necessary, providing a compressed margin, which can also be elastic when the air bag column is excluded, avoiding the stiffness of the plastic pillow body.

[0044] Further, an elastic connecting sleeve is arranged between the pillow body 1 and the edge of the sunken area 211, which is used to cover the gap of the suspended pillow body 1 and prevent foreign matter from entering, and also plays a role in auxiliary positioning of the pillow body 1. The elastic connecting sleeve is preferably a bellows 7, both ends of the bellows 7 are formed with a reverse edge 71 for abutment, the upper end of the reverse edge 71 abuts against the edge of the pillow body 1 and is clamped and fixed by the support plate 11; the lower end of the reverse edge 71 abuts against the edge of the cover sunken area 211 and is pressed and fixed by a pressing ring 22. The bellows 7 has a good shape, and of course the scheme of using elastic cloth can also meet the requirements.

[0045] As a preferred embodiment, the pillow 1 is longitudinally distributed with a headrest area 12 and a neckrest area 13, and is in an inclined shape with the neckrest area 13 being higher and the headrest area 12 being lower; the neckrest area 13 is in a U-shaped streamline structure that matches the curve of the human neck, and has protrusions 131 on the two lateral sides, and gradually narrows from the protrusions 131 along the edges and extends to the headrest area 12. That is, the central axis of the pillow 1 is in a concave structure, and the neckrest area 13 organically forms a lifting for the neck, while the head is supported by the headrest area 12 to keep natural drooping; especially in front and back swinging, obvious stretching action can be generated for the head; in left and right swinging, necessary side pushing force can be formed by the protrusions 131 surrounding the two sides of the neck.

[0046] In addition to the above-mentioned mechanical swinging and physiotherapy, existing mature photoelectric physiotherapy means can be superimposed to realize more comprehensive use value. For example, the pillow 1 is formed with a head pressing concave area 121 on the headrest area 12, and a soft rubber pad 122 is attached to the head pressing concave area, the surface of the soft rubber pad 122 is uniformly distributed with small protrusions to improve comfort and have certain adhesion to avoid position drift when the head swings; the pillow 1 is provided with a light transmission area 132 at least at the center position of the neckrest area 13, and neck pressing concave areas 133 are symmetrically formed on both sides of the light transmission area 132, and a conductive sheet 134 is attached to the neck pressing concave areas 133, and a heating sheet can also be installed on the back of the conductive sheet 134 to provide auxiliary heating; an infrared lamp 135 is installed inside the light transmission area 132, and the conductive sheet 134 is connected with a medium and low frequency pulse circuit on the electric control board 8, and the medium and low frequency pulse output and the pulse magnetic field generator 82 and the infrared lamp 135 are all controlled by the electric control board 8. With the aid of the infrared lamp 135, infrared physiotherapy can be provided, and the heating sheet on the back of the conductive sheet 134 can provide certain heat to play a hot compress role. More specifically, the medium and low frequency pulse generated by the electric control board 8 implements pulse physiotherapy on the neck through the conductive sheet 134, and at the same time, the electric control board 8 controls the pulse magnetic field generator 82 to generate a pulse magnetic field, and the pulse magnetic field can provide physiotherapy effect.

[0047] The pillow 1 is a non-light transmission material, that is, a central axis long groove is formed at the center position, and a light transmission cover is arranged to form the light transmission area 132.
