A heating component is located inside the body near the upper surface. This device has multiple functions such as thermotherapy, magnetic therapy, and pulse therapy, providing auxiliary treatment and health care for the lumbar region.
[0005] The aforementioned existing technologies all use only one airbag, which, while providing support for the waist, cannot achieve more detailed segmented support and is insufficient to meet personalized needs. Therefore, providing a more reasonable technical solution is the object of this invention. Invention content:
[0006] The purpose of this invention is to design a lumbar physiotherapy device that is suspended on a surface and can be lifted and pulled by an airbag assembly.
[0007] The technical solution of this utility model is implemented as follows: a lumbar spine physiotherapy device includes a bottom shell, a top shell, and an elastic plate embedded in the top shell; characterized in that: a physiotherapy device is suspended on the surface of the elastic plate, and an airbag assembly that can lift the elastic plate is provided on the lower side; an electronic control board for driving the physiotherapy device and the airbag assembly, and a battery for power supply are provided in the space enclosed by the top shell and the bottom shell.
[0008] The elastic plate has a compressible corrugated ring formed at the edge of the projection area of the physiotherapy device, and the physiotherapy device is suspended and supported above the elastic plate by means of the corrugated ring.
[0009] The faceplate is formed with a groove for installing the elastic plate and a recessed area for installing the airbag assembly. Screw holes are evenly distributed in the groove, and the elastic plate is embedded in the groove by means of a pressure ring. The pressure ring is integrally formed with a screw post corresponding to the position of the screw hole. The screw post passes through the reserved hole of the elastic plate and is inserted into the screw hole, and is locked by a screw that enters from one side of the screw hole.
[0010] The airbag group consists of two or more airbags arranged in two columns on the left and right sides of the central axis and multiple rows on the top and bottom. Each airbag group is connected to an air pump via a solenoid valve on the bottom shell. The solenoid valve independently controls the inflation and deflation of each airbag group. Each airbag group consists of one to three stacked airbags, and the airbags in each airbag group are interconnected.
[0011] In a preferred embodiment, the physiotherapy device includes a partitioned low-frequency pulse module and an infrared module. The low-frequency pulse module includes a conductive sheet and a sheet holder, with the conductive sheet embedded in the sheet holder and mounted on the corrugated ring of the elastic plate via the sheet holder. The infrared module includes an infrared lamp plate and a lampshade positioned above the infrared lamp plate. Both the infrared lamp plate and the lampshade are locked in the lamp holder and mounted on the corrugated ring of the elastic plate via the lamp holder. Both the sheet holder and the lamp holder are positioned above the corresponding airbags in the airbag assembly.
[0012] The elastic plate is molded from elastic plastic or silicone material. The plate holder in the low-frequency pulse module and the lamp holder in the infrared module are embedded in the edge of the corrugated ring of the elastic plate through inlay injection molding.
[0013] A pad is provided between the low-frequency pulse module and the airbag. The upper part of the pad abuts against the elastic plate around the plate holder, and the lower part abuts against the airbag.

[0036] Referring to Figures 1 to 5, the lumbar spine physiotherapy device includes a bottom shell 1, a top shell 2, and an elastic plate 3 embedded in the top shell. The elastic plate 3 is molded from elastic plastic or silicone material, and physiotherapy devices are suspended on its surface. An airbag assembly 4 is provided below the elastic plate 3 to lift it up. Within the space enclosed by the top shell 2 and the bottom shell 1, an electronic control board 5 is provided to drive the physiotherapy devices and the airbag assembly 4, as well as a battery 6 for power supply. The physiotherapy devices include a low-frequency pulse module 7 and an infrared module 8. On one side of the bottom shell 1, a power switch 51 for the electronic control board 5, an external connector 75 for the low-frequency pulse module, and a charging port 61 are provided.
[0037] More specifically, the elastic plate 3 has a compressible corrugated ring 31 formed at the edge of the projection area of the physiotherapy device. The physiotherapy device is suspended and supported above the elastic plate 3 by means of the corrugated ring 31. The elasticity of the corrugated ring 31 maintains the tendency to support the physiotherapy device, and it can be compressed under the pressure of the human body, thereby ensuring close contact with the body.
[0038] The assembly structure of the elastic plate 3 includes a groove 21 formed on the face shell 2 and a recessed area 22 within the space enclosed by the groove. Screw holes 211 are evenly distributed within the groove 21. The elastic plate 3 is embedded in the groove 21 by means of a pressure ring 23. A screw post 231 is integrally formed on the pressure ring 23 corresponding to the position of the screw hole 211. The screw post 231 passes through a pre-drilled hole in the elastic plate 3 and is inserted into the screw hole 211, and is secured by a screw entering from one side of the screw hole 211. This ensures that the elastic plate 3 and the face shell 2 are firmly connected without affecting the undulation of the elastic plate 3. The recessed area 22 is used to install the airbag assembly 4.
[0039] The airbag group 4 consists of two or more airbags arranged in two rows on the left and right sides of the central axis and multiple rows on the top and bottom. It is connected to the air pump 42 via the solenoid valve 43 set on the bottom shell 1. The solenoid valve 43 independently controls the inflation and deflation of each airbag group 4. In this example, there are six airbag groups, three on each side and three on the top and bottom. Each airbag group 4 is composed of one to three airbags 41 stacked together. The airbags 41 in each airbag group are interconnected, so that each airbag group unit can independently control the inflation and deflation of the airbags to adjust the lifting and traction or left and right swaying relaxation of different positions of the lumbar spine to meet different needs.
[0040] Furthermore, the physiotherapy device preferably includes a mid-to-low frequency pulse module 7 and an infrared module 8 arranged in separate zones. The mid-to-low frequency pulse module 7 includes a conductive sheet 71 and a sheet holder 72. The conductive sheet 71 is embedded in the sheet holder 72, which in turn is embedded in the corrugated ring 31 of the elastic plate. In addition, a heating element 74 is provided between the conductive sheet 71 and the sheet holder 72, and this heating element 74 is electrically connected to the electronic control board 5. The conductive sheet 71 is generally made of stainless steel, and the heating element 74 generates a heat therapy effect.
[0041] The infrared module 8 includes an infrared lamp plate 81 and a lamp cover 82 disposed above the infrared lamp plate 81; both the infrared lamp plate 81 and the lamp cover 82 are locked on the lamp holder 83, which is embedded in the corrugated ring 31 of the elastic plate by means of the lamp holder 83; both the plate holder 72 and the lamp holder 83 are disposed above the corresponding airbag 41 of the airbag group, so that when the airbag group 4 is inflated, it can directly drive the physiotherapy device to be lifted.
[0042] The aforementioned plate holder 72 and lamp holder 83 are embedded in the corrugated ring 31. Preferably, when the elastic plate 3 is molded from plastic or silicone material, the plate holder 72 and lamp holder 83 are directly embedded in the edge of the corrugated ring 31 of the elastic plate through an inlay injection molding process to form a firm fixed relationship.
[0043] Furthermore, a pad 73 is provided between the low-frequency pulse module 7 and the airbag. The upper part of the pad 73 abuts against the elastic plate 3 around the base 72, and the lower part abuts against the airbag 41. A positioning connection is formed by inserting a positioning pin 32 inside the elastic plate into the through hole 731 of the pad. The pad 73 is used to adjust the distance between the pad and the airbag, keeping it approximately equal to the thickness of the infrared module 8. Specifically, the pad 73 has a recessed area 732 formed corresponding to the base 72, which does not hinder the compression and downward movement of the low-frequency pulse module 7. The infrared module also has a pulse magnetic generator 9 on the lamp holder 83. Utilizing the penetrability of the pulse magnetic generator 9, infrared rays are organically superimposed to form a two-in-one physiotherapy effect.
[0044] To reduce discomfort caused by the height difference between a single airbag group and other airbag groups when inflating, a flexible plastic plate 44 is placed over the airbag group 4, allowing for a smooth transition between the airbag groups. The upper surface of the flexible plastic plate 44 abuts against the bottom of the plate holder 72 and the lamp holder 83, and the lamp holder 83 is provided with a locking structure to prevent slippage. As shown in the figure, the protrusion 831 at the bottom of the lamp holder 83 engages with the hole 441 on the flexible plastic plate 44.
[0045] The elastic plate 3 is designed to conform to the curve of the human waist. An infrared module 8 is positioned at the central arched section. Conductive plates 71 of a low-frequency pulse module 7 are located above and below the infrared module 8, and these conductive plates 71 are symmetrically arranged to the left and right, resulting in four electrode points. This design prevents interruption of the pulse therapy due to any conductive plate becoming airborne during traction. The elastic plate 3, conforming to the curve of the human waist, is essentially formed by stretching the curved shell 2. The shell 2 also has waist-supporting wings 24 on both sides, serving as a support for the waist and allowing the physiotherapy device to be used. Furthermore, physiotherapy devices, such as compression airbags or vibration motors, can be added to the waist-supporting wings 24 to enhance the overall therapeutic capabilities of the device.
