Description

Technical Field

[0001] This invention relates to the field of lumbar health care technology, and in particular to a transcutaneous acupoint electrical stimulation lumbar massager. Background Technology

[0002] Currently, lumbar health care devices on the market are mainly divided into two categories: one is transcutaneous electrical acupoint stimulation (TEAS) devices, which apply low-frequency pulsed current to the skin through electrode pads to stimulate nerves or acupoints to achieve analgesia and soothing effects. However, it lacks physical kneading, pressing and other tactile sensations, resulting in a limited user experience and insufficient simulation of the traditional massage experience;

[0003] Another type is mechanical massagers, such as massage pillows and massage chairs, which use motors to drive mechanical devices to simulate the tapping, kneading, and vibration movements of human hands. However, their stimulation only acts on the muscle fascia level and cannot cause the muscles to contract and relax like electrical stimulation, thus lacking in massage depth.

[0004] While some existing technologies attempt to integrate the two into a single device, the electrical stimulation module and the mechanical massage module typically operate independently, representing a functional "overlay" rather than "fusion" and "synergy." This results in a failure to achieve a synergistic effect where "1+1>2" in treatment, leading to a fragmented user experience.

[0051] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0052] Example 1

[0053] A specific embodiment of the present invention discloses a transcutaneous acupoint electrical stimulation lumbar massager, such as... Figure 1 , Figure 2 As shown, a transcutaneous acupoint electrical stimulation waist massager includes a cover 1, electrode pads 2, a back plate 3, a lifting mechanism 4, a massage mechanism 6, and a side support mechanism 7; the lifting mechanism 4 is installed on one side of the back plate 3, the massage mechanism 6 is connected to the side support mechanism 7, the cover 1 is integrally fitted over the back plate 3, the lifting mechanism 4, the massage mechanism 6, and the side support mechanism 7, and a plurality of electrode pads 2 are provided on the surface of the cover 1.

[0054] The electrode pad 2 is used to electrically stimulate the skin of the waist, relax the deep muscles, and stimulate acupoints to achieve a certain numbing effect. At this time, even when the mechanical massage force is slightly greater, there is still good massage comfort.

[0055] The lifting mechanism 4 can adjust the height of the massage mechanism 6, allowing it to adapt to people of different heights and lumbar spine lengths.

[0056] The side support mechanism 7 can support the waist of the person being massaged, while also recognizing the body shape of the person being massaged.

[0057] The cover 1 is made of flexible material, such as pure cotton fabric, chemical fiber fabric, and leather.

[0058] The back panel 3 is used for support and can be placed on the bed surface or on the back of a chair.

[0059] The massage facility 6 provides mechanical massage to the recipients.

[0060] Preferred, such as Figure 3As shown, the lifting mechanism 4 includes a first motor 42, a first driving gear 43, a first driven gear 44, a first transmission rack 45, a lateral adjustment assembly 46, a cross-shaped synchronizing rod 47, a hollow sleeve 48, and a lifting execution assembly 49. The hollow sleeve 48 is fixed to both sides of each of the multiple lateral adjustment assemblies 46. The lifting execution assembly 49 is installed between the hollow sleeves 48 on the same side, and each hollow sleeve 48 on the same side is connected to one of the cross-shaped synchronizing rods 47. The first driven gear 44 is fixed to the lower part of the cross-shaped synchronizing rod 47. The first driven gear 44 is connected to the first driving gear 43 through the first transmission rack 45. The first motor 42 is installed on one side of the first driving gear 43.

[0061] The first motor 42 drives the first drive gear 43 to rotate forward or reverse. The first drive gear 43 drives the first driven gear 44 to rotate forward or reverse through the first transmission rack 45. The first driven gear 44 drives the cross-shaped synchronizing rod 47 to rotate forward or reverse. The cross-shaped synchronizing rod 47 drives the lifting actuator 49 to perform the rising or falling operation.

[0062] Preferably, the two ends of the cross-shaped synchronizing rod 47 are connected to the back plate 3 via a second bearing seat.

[0063] Preferably, the first motor 42 and the back plate 3 are fixedly connected by a first support plate 41.

[0064] Existing mechanical massage institutions are fixed and do not adapt to people of different heights, weights, and builds, such as men, women, the elderly, and children. They use fixed one-size-fits-all mechanical massage institutions, so people of different heights, weights, and builds will have different massage effects and experiences, and cannot allow most people to enjoy a massage effect that is suitable for their body type.

[0065] The lifting mechanism 4 addresses the compatibility of massage recipients of different body types with varying heights, specifically optimizing the fit for individuals with different lumbar spine lengths.

[0066] When massaging recipients with different lumbar spine lengths, the operation of the first motor 42 can be controlled to adjust and adapt to the different lumbar spine lengths of the recipients. The output shaft of the first motor 42 drives the first drive gear 43 to rotate, the first drive gear 43 drives the first transmission rack 45 to rotate, the first transmission rack 45 drives the first driven gear 44 to rotate, the first driven gear 44 drives the cross-shaped synchronous rod 47 to rotate, and the cross-shaped synchronous rod 47 drives multiple lifting actuators 49 to perform rising or falling operations. At this time, the width between the lifting actuators 49 changes to adapt to the different lumbar spine lengths of the recipients.

[0067] Preferred, such as Figure 4As shown, the lifting actuator 49 includes a first bearing seat 491, an internal threaded sleeve 492, and an external threaded sleeve 493. The lower part of the first bearing seat 491 is rotatably connected to the internal threaded sleeve 492, and the interior of the internal threaded sleeve 492 is threadedly connected to the external threaded sleeve 493. The upper hollow sleeve 48 is fixedly connected to the first bearing seat 491, and the lower hollow sleeve 48 is fixedly connected to the external threaded sleeve 493. A cross-grooved disc is fixedly attached to the upper part of the internal threaded sleeve 492, and the cross-grooved disc is slidably connected to the cross-shaped synchronizing rod 47.

[0068] The cross-shaped synchronizing rod 47 drives the internal threaded sleeve 492 to rotate. The internal threaded sleeve 492 rises or falls under the action of the threaded connection of the external threaded sleeve 493, thereby realizing the lifting and lowering of the lateral adjustment component 46 and the hollow sleeve 48.

[0069] Preferred, such as Figure 9 As shown, the lateral adjustment assembly 46 includes a hollow sliding frame 461, a slider 462, and a synchronous connecting rod 463. Two sliders 462 are symmetrically arranged inside the hollow sliding frame 461. The upper inner wall of the hollow sliding frame 461 has multiple evenly arranged pin holes. A spring pin is provided on one side of each slider 462, and the spring pin can be inserted into the pin hole. The synchronous connecting rod 463 is installed between the spring pins. When the synchronous connecting rod 463 is pressed down, it can pull the spring pin out of the pin hole, allowing the hollow sliding frame 461 and the slider 462 to slide freely between them.

[0070] Some people receiving massages have a certain degree of lumbar spine misalignment to the left or right. Existing mechanical massage institutions cannot adapt to this group of people when massaging them. As a result, when massaging the muscles on both sides of the lumbar spine, they may massage the lumbar spine itself, which can easily cause discomfort and fail to relax the lumbar muscles.

[0071] The lateral adjustment component 46 addresses the need for adaptation for individuals with a certain degree of lumbar spine displacement to the left or right.

[0072] Some massage recipients have a certain degree of lumbar vertebral misalignment to the left or right. In this case, the synchronous connecting rod 463 of the lateral adjustment component 46 that needs lateral adjustment can be pressed down and moved to the left or right. When it is moved to match the lateral misalignment of the massage recipient's lumbar vertebrae, the pressing finger is released to complete the adaptation of the lumbar vertebrae of such massage recipients.

[0073] Preferably, the massage mechanism 6 includes support rods 61 and rotating vibration massage balls 62; one end of each of the six support rods 61 is symmetrically distributed and fixed to the first fixing component 51, the second telescopic component 52 and the third telescopic component 53.

[0074] The rotating vibrating massage ball 62 is connected to a power source.

[0075] Preferably, the side support mechanism 7 includes a support side plate, an airbag, and a pressure sensor; there are two support side plates, which are fixed to both sides of the massage mechanism 6. The support side plates are fixedly connected to the support rod 61 on the lower outer side through the rod body. An airbag is installed on one side of the support side plate, and the pressure sensor is installed inside the airbag.

[0076] Preferably, each of the electrode plates 2 can be individually controlled to be energized.

[0077] Electrode 2 is a circular piece with a diameter of 30 mm.

[0078] Example 2

[0079] In one specific embodiment of the present invention, a width adjustment mechanism 5 is added to embodiment 1, such as... Figure 7 and Figure 8 As shown, the lifting mechanism 4 is equipped with multiple sets of width adjustment mechanisms 5, and multiple massage mechanisms 6 are fixed to the width adjustment mechanisms 5. The width adjustment mechanism 5 includes a first fixing component 51, a second telescopic component 52, a third telescopic component 53, and a telescopic control component 54. The first fixing component 51 is fixedly connected to the lifting mechanism 4, and telescopic second telescopic components 52 are installed on both sides of the first fixing component 51. The third telescopic component 53 is installed on the outside of the second telescopic component 52. The telescopic control component 54 is provided inside the first fixing component 51, the second telescopic component 52, and the third telescopic component 53.

[0080] Preferred, such as Figure 8 As shown, the first fixing component 51 includes a first sleeve rod 511 and a first concave strip 512; the first sleeve rod 511 is radially fixed with the first concave strip 512.

[0081] The second telescopic component 52 includes a second sleeve rod 521 and a second concave strip 522; the second sleeve rod 521 is radially fixed with the second concave strip 522, the second sleeve rod 521 is slidably connected to the first sleeve rod 511, the second concave strip 522 is slidably connected to the first concave strip 512, and both sides of the second sleeve rod 521 are provided with threads.

[0082] The third telescopic component 53 includes a third sleeve rod 531, an outer sliding rod 532, a third bearing 533, a hollow external threaded sleeve rod 534, and an inner sliding rod 535. One end of the third sleeve rod 531 is equipped with the outer sliding rod 532 and the third bearing 533. The hollow external threaded sleeve rod 534 is installed on one side of the third bearing 533. The inner sliding rod 535 is fixed to the inner side of the hollow external threaded sleeve rod 534. The hollow external threaded sleeve rod 534 is threadedly connected to the second sleeve rod 521. The outer sliding rod 532 is slidably connected to the second concave strip 522.

[0083] The telescopic control assembly 54 includes an external threaded rod 541, a strip-shaped through groove 542, and a sliding groove 543. The threads of the external threaded rod 541 are symmetrically arranged, and the middle part of the external threaded rod 541 is a smooth round rod. The external threaded rod 541 is radially provided with a sliding groove 543, and the strip-shaped through groove 542 is provided inside the external threaded rod 541. The sliding groove 543 is slidably connected to the inner sliding rod 535. The sliding groove 543 can drive the hollow external threaded sleeve 534, which is fixedly connected to the inner sliding rod 535, to rotate. The external threaded rod 541 is threadedly connected to the second sleeve 521. When the external threaded rod 541 rotates, it can drive the second sleeve 521 to extend and retract along the first sleeve 511 under the limiting of the first concave strip 512 and the second concave strip 522.

[0084] Existing mechanical massage institutions are fixed and do not adapt to people of different heights, weights, and builds, such as men, women, the elderly, and children. They use fixed one-size-fits-all mechanical massage institutions, so people of different weights and builds will have different massage effects and experiences, and cannot allow most people to enjoy a massage effect that is suitable for their body type.

[0085] The width adjustment mechanism 5 is designed to adapt to people of different body sizes, ensuring that massagers of all body sizes can reach the muscles that need to be massaged.

[0086] When adjusting the width, the external threaded rod 541 rotates and is threadedly connected to the second sleeve rod 521. Under the limit of the first concave strip 512 and the second concave strip 522, the second sleeve rod 521 extends and retracts along the first sleeve rod 511. At the same time, the strip groove 542 on the external threaded rod 541 drives the inner sliding rod 535 to rotate. The inner sliding rod 535 drives the hollow external threaded rod 541 to rotate. When the hollow external threaded rod 541 rotates, it rotates and extends and retracts under the action of the thread on the second sleeve rod 521. At this time, the hollow external threaded rod 541 drives the third sleeve rod 531 to extend and retract through the third bearing 533, thus realizing the extension and retraction of the second extension component 52 and the third extension component 53.

[0087] The width adjustment mechanism 5 can adjust the width of the massage mechanism 6, so that the massage mechanism 6 can be adapted to people of different sizes.

[0088] Example 3

[0089] In one specific embodiment of the present invention, a width adjustment synchronization mechanism 8 is added to embodiment 2, such as... Figure 5 and Figure 6 As shown, the width adjustment mechanism 5 is connected to the width adjustment synchronization mechanism 8 on one side. The width adjustment synchronization mechanism 8 includes a second motor 82, a second rotating gear 83, a second rack 84, a rotating plate 85, a second intermediate rotating gear 86, a connecting plate 87, a pressure roller 88, and a strip rod 89. The strip rod 89 is slidably connected to the strip groove 542. One end of the strip rod 89 is fixed to the second rotating gear 83. The second rotating gear 83 has a first annular groove symmetrically provided in the middle. The second rotating gear 83 is hinged to the adjacent second rotating gear through the annular groove. The rotating plates 85, numbered 83, are hinged together by a second intermediate gear 86 with a second annular groove. Adjacent second rotating gears 83 and second intermediate gears 86 mesh with a second annular rack 84. The two sides of the second intermediate gear 86 are hinged to one end of the connecting plate 87, and the other end of the connecting plate 87 is hinged to the pressure roller 88. The pressure roller 88 enables the second rack 84 and the second intermediate gear 86 to mesh. The lowest second rotating gear 83 is fixedly connected to the output shaft of the second motor 82.

[0090] The second motor 82 drives one of the second rotating gears 83 to rotate, and the second rotating gear 83 drives the other second rotating gears 83 to rotate through the second intermediate rotating gear 86, the pressure roller 88, and the second rack 84.

[0091] When the width adjustment mechanism 5 is adjusting the width, it drives the massage mechanism 6 to gradually narrow the massage width, and the side support mechanism 7 narrows accordingly. When it comes into contact with the waist of the person being massaged, the airbag is squeezed. When the pressure sensor detects that the pressure inside the airbag has reached the preset value, the second motor 82 of the width adjustment synchronization mechanism 8 stops working.

[0092] Preferably, the second motor 82 and the supporting side plate are fixedly connected by a second supporting plate 81.

[0093] The width adjustment synchronization mechanism 8 can synchronously adjust the various components within the massage mechanism 6.

[0094] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
