Description

Technical Field

[0001] This invention belongs to the field of daily necessities, and specifically relates to a multi-directional airbag cervical traction device, particularly a physiotherapy solution that uses multiple airbags to alternately inflate and deflate to achieve cervical traction and relaxation. Background Technology

[0002] Most cervical traction pillows on the market currently use airbags to push the pillow upwards, achieving a traction and stretching effect on the cervical spine through repeated lifting movements. However, while this repetitive, single upward movement does provide traction, it can also cause muscle and ligament fatigue and damage, significantly reducing the traction effect. For example: CN201921818771.6 discloses a therapeutic neck pillow, comprising: a shell; a massage body disposed on the shell for massaging the head and neck of a human body; a first massage device fixedly installed within the shell for driving the massage body to swing relative to the shell to stretch and massage the head and neck of the human body, namely a rocker mechanism composed of a first airbag and a spring, responsible for the reciprocating motion of the pitch angle; and a second massage device fixedly installed within the shell for driving the shell to move up and down to correct the cervical spine, namely a second airbag responsible for the lifting and lowering motion. Both techniques involve movements on the central axis of the human body.

[0003] CN202223197646.2 discloses a neck massager, including a massager housing, an airbag massage assembly, a head support, and an inflation / deflation mechanism. The inflation / deflation mechanism includes a control module and an air pump connected to the airbag massage assembly. The massager housing includes an upper neck traction assembly and a lower neck traction assembly connected by a seesaw mechanism. The seesaw mechanism includes an upper lifting airbag on one side and an elastic element on the other side, with the upper lifting airbag connected to the air pump. The airbag massage assembly and the head support are both mounted on the upper neck traction assembly. Compared to the former, this design reduces the lifting motion generated by the lifting airbag.

[0004] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0005] The purpose of this invention is to develop a multi-directional airbag cervical traction device that can perform both pitching and lateral swaying movements.

[0006] The technical solution of the present invention is implemented as follows: a multi-directional airbag cervical traction device, including a pillow body, a seat body and airbag columns for supporting the pillow body, characterized in that: three or more sets of airbag columns forming a polygon are arranged between the pillow body and the seat body (2), and the airbag columns form a floating support for the pillow body; the airbag columns are respectively connected to an air pump via electromagnetic valves, and the electromagnetic valves are controlled by an electronic control board to inflate and deflate the airbag columns, thereby driving the pillow body to rise, fall and swing.

[0007] A swing support column is also provided between the middle of the pillow body and the seat body, and the pillow body can swing under the drive of the airbag column with the swing support column as the fulcrum.

[0008] The airbag columns are in four groups, symmetrically distributed in a quadrilateral shape on both sides of the central axis of the pillow body. Each group consists of one to three airbag columns arranged side by side, and the airbag columns in the same group are interconnected. Each airbag column is composed of one or more stacked airbag bodies.

[0009] In a preferred embodiment, both the pillow body and the seat body are plastic molded shells, and the bottom of the pillow body is provided with a support plate for the airbag column and the swing support column to abut against each other; an elastic connecting sleeve is provided between the edges of the pillow body and the seat body to cover the gaps in the suspension of the pillow body.

[0010] The seat is larger than the pillow body, and a cover is provided on the top. The cover has a recessed area with an area larger than the projected area corresponding to the projection area of ​​the pillow body, and the outer edge is an arched edge. The recessed area has a through hole for the airbag inflation / deflation nozzle to enter at the position of the airbag column. The support plate has an upward arched positioning groove corresponding to the position of the airbag column, and a positioning hole is opened in the center of the positioning groove. A positioning expansion pin is provided at the top of the airbag column, and the positioning expansion pin passes through the positioning hole to form the positioning of the top of the airbag column.

[0011] A swing support column is provided between the support plate at the bottom of the pillow body and the middle of the sinking area of ​​the cover. The swing support column has a ball head and a screw section. The ball head is movably positioned in the ball head seat on one side of the sinking area or the side of the support plate. The screw section passes through the support plate or the sinking area and is locked at the end by a limiting nut.

[0012] The elastic connecting sleeve is a corrugated tube with folded edges formed at both ends for abutment. The upper folded edge abuts against the edge of the pillow body and is clamped and fixed by the support plate; the lower folded edge abuts against the edge of the cap sinking area and is pressed and fixed by a pressure ring.

[0013] The pillow body is longitudinally distributed with a head pillow area and a neck pillow area, and is inclined with the neck pillow area higher and the head pillow area lower. The neck pillow area conforms to the U-shaped streamlined structure of the curve of the human neck, and has protrusions on both sides in the lateral direction, which gradually narrows from the protrusions along the edge and extends to the head pillow area.

[0014] The pillow body has a head-pressing recess formed in the headrest area, and a soft rubber pad is attached to the head-pressing recess. The surface of the soft rubber pad is evenly distributed with small bumps. The pillow body has a light-transmitting area at least in the center of the neck-rest area, and symmetrical neck-pressing recesses are formed on both sides of the light-transmitting area. A conductive sheet is attached to the neck-pressing recess. An infrared lamp is installed inside the light-transmitting area. A pulse magnetic generator is installed on the back of the infrared lamp. The conductive sheet is connected to the low-frequency pulse circuit of the electronic control board set on the seat. The low-frequency pulse input of the conductive sheet, the pulse magnetic generator, and the infrared lamp are all controlled by the electronic control board.

[0015] The air pump is externally mounted and connected to a solenoid valve mounted on the seat via an air pipe. The electronic control board is mounted on the recessed area formed by the seat. A charging port, an air nozzle, a power switch, and an external connector for medium and low frequency pulses are also provided on the side of the seat.

[0016] This invention uses three or more airbag columns to form a polygonal structure, which can provide balanced support for the pillow. By inflating or deflating one side of the airbag column, one can perform pitching or lateral swaying movements. If the airbag columns are inflated or deflated in sequence, a continuous superimposed composite movement of pitching and swaying will be produced, which greatly enriches the traction techniques for the neck and the therapeutic effect is also predictable.

[0018] Reference Figures 1 to 5 The multi-directional airbag cervical traction device includes a pillow body 1, a seat body 2, and airbag columns 3 for supporting the pillow body. There are three or more sets of airbag columns 3 arranged in a polygon between the pillow body 1 and the seat body 2. The figure shows four sets of airbag columns 3, which form a quadrilateral. The airbag columns 3 provide suspension support for the pillow body 1. The airbag columns 3 are connected to the air pump 5 via solenoid valves 4. The solenoid valves 4 are controlled by the electronic control board 8 to inflate and deflate the airbag columns 3, driving the pillow body 1 to rise, fall, and swing.

[0019] This example preferably features an external air pump 5, connected to a solenoid valve 4 mounted on the seat 2 via an air tube 51. An electronic control board 8 is positioned in the recessed area of ​​the seat 2. The side of the seat also features a charging port 23, an air nozzle 24, a power switch 25, and an external connector 26 for low-frequency pulse therapy. The charging port 23 provides for battery charging. The air nozzle 24, connected to the air tube 51, can be a fixed structure or a pluggable structure for easy disassembly and storage. The external connector 26 provides external expansion capabilities for external low-frequency pulse therapy. Furthermore, the air tube 51 uses a flexible composite cable and has a hollow structure with independent air tube channels and control line channels 52, electrically connecting the electronic control board 8 and the air pump 5 to control its operation. In this example, the air pump 5 is housed in a noise-reducing box 53. A wireless remote control 83 is positioned on the surface of the noise-reducing box 53, magnetically attached to it, and can also be removed for convenient remote operation. Of course, it is also possible that the remote control 83 is directly located on the side of the base 2, or that there are control panels in both locations.

[0020] Furthermore, a swing support column 6 is provided between the middle of the pillow body 1 and the seat body 2. The pillow body 1 can swing around the swing support column 6 as a fulcrum under the drive of the airbag column 3. That is to say, the height of the swing support column 6 is between the uninflated height and the inflated height of the airbag column 3. The swing support column 6 is located at the center of the multiple sets of airbag columns 3, providing height limitation and swing fulcrum. Under the drive of the airbag column 3, due to the restriction of the swing support column 6, one side of the pillow body 1 rises, and the corresponding other side is forced to descend. This allows the pillow body 1 to generate not only upward traction but also backward traction. By changing the length of the swing support column 6, the tilt height of the pillow body can be changed to meet the needs of neck physiotherapy.

[0021] Ideally, four sets of airbag columns 3 should be arranged symmetrically in a quadrilateral shape on both sides of the central axis of the pillow body 1, with two sets of airbag columns 3 supporting each side, providing more stable support for the pillow body 1. Each set consists of one to three airbag columns 3 arranged side by side, and the airbag columns 3 in the same set are interconnected. Each airbag column 3 is composed of one or more stacked airbag bodies 31. In this example, only one airbag column 3 is set in each set, forming a regular quadrilateral, but it can also be an isosceles trapezoid or a rhombus. One diagonal of the rhombus overlaps with the central axis of the pillow body. Although the support stability is not as good as that of a quadrilateral, it is more flexible in driving the forward, backward, left and right swing. Only one airbag column 3 needs to be inflated, while the others are deflated.

[0022] Furthermore, both the pillow body 1 and the seat body 2 are molded plastic shells. The pillow body 1 has a support plate 11 inside. The seat body 2 is larger than the pillow body 1 and has a cover 21 on its upper part. The cover 21 has a recessed area 211 with an area 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 recessed area 211 of the cover provide contact between the airbag column 3 and the swing support column 6 at both ends. More specifically, the recessed area 211 has a through hole 213 for the airbag inflation / deflation nozzle 311 to enter at the projected position of the airbag column 3, and a ball head seat 214 for positioning the swing support column 6 is located at the center. The ball head seat 214 is a split-molding structure and is locked to the lower surface of the cover 21. If space permits, the ball head seat 214 can also be directly locked to the upper surface of the cover 21. Alternatively, the swing support 6 can be positioned on one side of the sunken area 211, with the top ball head abutting against the ball head seat on one side of the support plate 11, which can also achieve the same function and is an equivalent technology to the above structure.

[0023] The support plate 11 and the sunken area 211 of the cover are parallel to each other, so that both ends of the multiple airbag columns 3 can be in contact. For this purpose, an upwardly arched positioning groove 111 is formed on the support plate 11 at the position corresponding to the airbag column, and a positioning hole 112 is opened in the center of the positioning groove 111. A positioning expansion pin 312 is provided on the top of the airbag column 3. The positioning expansion pin 312 passes through the positioning hole 112 to form the positioning of the top of the airbag column 3, so as to prevent the airbag column 3 from moving.

[0024] The swing support 6 has a ball head 61 and a screw section 62. The ball head 61 is movably positioned within the ball head seat 214, and the screw section 62 passes through the support plate 11 and has a limit nut 63 at its end. The screw section 62 and the support plate 11 are in a fixed relationship, or they can be in a sliding relationship. A fixed relationship makes the airbag column 3 more sensitive when driven, while a sliding relationship allows the pillow body 1 to have lifting space without affecting the swing, meeting different height requirements. If necessary, a spring can be fitted on the screw section to provide a margin for compression and elasticity when the airbag column is released, avoiding the stiffness of the plastic pillow body.

[0025] Furthermore, an elastic connecting sleeve is provided between the pillow body 1 and the edge of the sinking area 211 to cover the gap where the pillow body 1 is suspended and to prevent foreign objects from entering. It also serves as an auxiliary positioning tool for the pillow body 1. The elastic connecting sleeve is preferably a corrugated tube 7. Both ends of the corrugated tube 7 are formed with folded edges 71 for abutment. The upper folded edge 71 abuts against the edge of the pillow body 1 and is clamped and fixed by the support plate 11; the lower folded edge 71 abuts against the edge of the sinking area 211 and is pressed and fixed by a pressure ring 22. The corrugated tube 7 has a good shape. Of course, the use of elastic fabric can also meet the requirements.

[0026] In a preferred embodiment, the pillow body 1 has a headrest area 12 and a neckrest area 13 distributed longitudinally, with the neckrest area 13 being higher and the headrest area 12 being lower. The neckrest area 13 conforms to the U-shaped streamlined structure of the human neck curve, and has protrusions 131 on both sides laterally, gradually narrowing from the protrusions 131 along the edges and extending to the headrest area 12. That is to say, the central axis of the pillow body 1 has a concave structure, the neck area 13 organically supports the neck, while the head remains naturally hanging down and is supported by the headrest area 12; especially when swinging back and forth, it can produce a significant stretching action on the head; when swinging left and right, it can also form the necessary lateral thrust by surrounding the neck with the protrusions 131.

[0027] In addition to the aforementioned mechanical swinging physiotherapy, existing mature photoelectric physiotherapy methods can be superimposed to achieve a more comprehensive application value. For example, the pillow body 1 has a head-pressing area 121 formed on the headrest area 12, and a soft rubber pad 122 is attached to the head-pressing area. The surface of the soft rubber pad 122 is evenly distributed with small bumps to improve comfort and has a certain adhesion to prevent the position from drifting when the head swings. The pillow body 1 has a light-transmitting area 132 at least in the center of the neck-rest area 13, and symmetrical neck-pressing areas 133 are formed on both sides of the light-transmitting area 132. A conductive sheet 134 is attached to the neck-pressing area 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-transmitting area 132. The conductive sheet 134 is connected to the medium-low frequency pulse circuit on the electronic control board 8. The medium-low frequency pulse output, the pulse magnetic generator 82, and the infrared lamp 135 are all controlled by the electronic control board 8. Infrared lamp 135 provides infrared therapy, and the heating pad on the back of conductive sheet 134 provides heat, serving as a hot compress. More specifically, the low-to-medium frequency pulses generated by the electronic control board 8 apply pulse therapy to the neck through conductive sheet 134, while the electronic control board 8 controls the pulse magnetic generator 82 to generate a pulse magnetic field, which provides a therapeutic effect.

[0028] The pillow body 1 is made of non-transparent material, that is, it has a central axial groove formed in the center position and is equipped with a light-transmitting cover to form a light-transmitting area 132.
