Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intelligent multifunctional nursing and massage device for the elderly. Background Technology

[0002] Elderly care devices refer to various types of equipment designed to meet the needs of the elderly in areas such as daily living assistance, health monitoring, and rehabilitation care. Below are some common classifications of elderly care devices: assisted living devices, rehabilitation training devices, health monitoring devices, and safety alarm devices. Elderly massage devices, specifically designed for the elderly within the rehabilitation training category, are used to relieve physical fatigue, improve blood circulation, and promote health. While elderly massage devices can provide a comfortable massage experience, they require caution due to the unique physical characteristics of the elderly, such as fragile bones, decreased sensory abilities, and limited operational capabilities.

[0003] However, some existing massage and nursing devices are inconvenient to adjust the massage stroke during the massage process, and can only massage a single position. The elderly have a lower pain tolerance, and massaging the same position for a long time can easily turn the massage into a "painful stimulus", which can aggravate muscle tension or joint discomfort. At the same time, some massage and nursing devices are not convenient to adjust the appropriate intensity and spacing when massaging different parts of the body, which limits their use. In addition, the complicated adjustment buttons are not easy for the elderly to operate.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent multifunctional nursing and massage device for the elderly to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent multifunctional nursing massage device for the elderly, comprising a massage body, with fixing straps on both sides of the massage body, a support frame fixedly installed inside the massage body, a rotary motor fixedly installed at the front end of the support frame, a strength adjustment mechanism installed at the rear end of the support frame, connecting rods rotatably installed on the left and right sides of the support frame, spiral grooves formed on the surface of the connecting rods, a movable block elastically slidably installed inside the massage body, a vibration mechanism installed on the movable block, a massage head connected to the front end of the movable block through the vibration mechanism, and an abutment block installed inside the massage body.

[0007] Preferably, the strength adjustment mechanism includes a rotating bearing, which is rotatably mounted on a support frame and connected to the output end of a rotary motor. A connecting plate is slidably mounted on the upper limit of the rotating bearing, and a cylindrical piston block is fixedly mounted on the connecting plate.

[0008] Preferably, the intensity adjustment mechanism further includes a rotating disk with a track groove, a friction pad on the inner wall of the track groove, and a rotating rod rotatably mounted on the rear side of the rotating disk. The rotating disk is rotatably mounted inside the massager body via the rotating rod.

[0009] Preferably, the piston block fixedly mounted on the connecting plate is slidably mounted in a track groove opened on the rotating disk, and the diameter of the piston block is the same as the width of the track groove.

[0010] Preferably, an oil cylinder is fixedly installed inside the rotating disk, and a piston rod is movably installed inside the oil cylinder. The piston rod is fixedly connected to a piston block, and the oil cylinder is connected to the outlet at the center of the back of the rotating disk through a hose.

[0011] Preferably, the intensity adjustment mechanism further includes a second oil cylinder, which is fixedly mounted on a movable block. The second oil cylinder is connected to the first oil cylinder via a hose. A limit spring is fixedly connected to the piston rod at the front end of the second oil cylinder. A movable block is connected to the front end of the limit spring, and the movable block is slidably mounted on the back of the massage head.

[0012] Preferably, the vibration mechanism includes a mounting block, which is fixedly mounted on a movable block. A limiting block is fixedly mounted on the mounting block and slidably mounted in a spiral groove. One side of the movable block is arc-shaped and is located on the movement trajectory of the connecting plate.

[0013] Preferably, the vibration mechanism further includes a deflection block, which is rotatably installed in the internal cavity of the moving block. A docking block is rotatably installed on the deflection block, and a vibration block is connected to the front end of the docking block. The vibration block is connected to the back of the massage head through a fixedly installed tension spring.

[0014] Preferably, the vibration mechanism further includes a movable rod, which is fixedly mounted on the deflection block. A sliding block is fixedly mounted on the movable rod, and the movable rod is slidably mounted in a cavity opened inside the connecting rod by means of the sliding block.

[0015] Preferably, the lower end of the massage head is provided with symmetrical arc-shaped protrusions, and the protrusions are correspondingly arranged with the arc-shaped blocks on the abutment block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention, through the intensity adjustment mechanism, allows the operator to rotate the rotating rod on the back of the massager to rotate the rotating disc when massaging muscle groups with less force, such as the abdomen. Under the action of the track groove and the piston block, the extension length of the connecting plate is controlled. At this time, the piston block is located at the bottom of the track groove, and the oil in the first oil cylinder is drawn out from the second oil cylinder through the piston rod and the hose. This reduces the compression of the limit spring by the piston rod, reduces the compression force of the limit spring on the massage head, and thus reduces the vibration intensity of the massage head. This allows the massage head to press the user's abdomen more gently. Conversely, by sending oil into the second oil cylinder, the pressure of the limit spring is increased, allowing the massage device to press on areas of the body with higher tolerance.

[0018] 2. In this invention, the connecting plate and the moving block abut against each other, causing the connecting plate to push the moving block to continuously shift to both sides under the drive of the rotary motor. At the same time, in conjunction with the aforementioned intensity adjustment mechanism, the massage force of the massage device decreases synchronously as the stroke length decreases, preventing muscle damage caused by prolonged pressure on the same position. Furthermore, during the sliding process of the moving block, the contact between the movable block at the bottom of the massage head and the abutting block causes the massage head to move up and down continuously, increasing the overall massage range and preventing massage omissions that could lead to inadequate muscle relaxation.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-11 This invention provides a technical solution: an intelligent multifunctional nursing massage device for the elderly, comprising a massage body 1, fixing straps 2 on both sides of the massage body 1, a support frame 3 fixedly installed inside the massage body 1, a rotary motor 4 fixedly installed at the front end of the support frame 3, an intensity adjustment mechanism at the rear end of the support frame 3, connecting rods 5 rotatably installed on the left and right sides of the support frame 3, spiral grooves 501 opened on the surface of the connecting rods 5, a movable block 6 elastically slidably installed inside the massage body 1, a vibration mechanism installed on the movable block 6, a massage head 7 connected to the front end of the movable block 6 through the vibration mechanism, and an abutment block 8 installed inside the massage body 1.

[0033] In one embodiment of the present invention, the strength adjustment mechanism includes a rotating bearing 9, which is rotatably mounted on a support frame 3. The rotating bearing 9 is connected to the output end of a rotary motor 4. A connecting plate 10 is slidably mounted on the upper limit of the rotating bearing 9, and a cylindrical piston block 11 is fixedly mounted on the connecting plate 10.

[0034] As one embodiment of the present invention, the intensity adjustment mechanism further includes a rotating disk 12, on which a track groove 1201 is provided, and a friction pad is provided on the inner wall of the track groove 1201. A rotating rod 13 is rotatably mounted on the rear side of the rotating disk 12, and the rotating disk 12 is rotatably mounted inside the massage machine body 1 through the rotating rod 13.

[0035] In one embodiment of the present invention, the piston block 11 fixedly installed on the connecting plate 10 is slidably installed in the track groove 1201 opened on the rotating disk 12, and the diameter of the piston block 11 is the same as the width of the track groove 1201.

[0036] In one embodiment of the present invention, an oil cylinder 14 is fixedly installed inside the rotating disk 12, and a piston rod 15 is movably installed inside the oil cylinder 14. The piston rod 15 is fixedly connected to the piston block 11, and the oil cylinder 14 is connected to the liquid outlet at the center of the back of the rotating disk 12 through a hose.

[0037] As one embodiment of the present invention, the intensity adjustment mechanism further includes an oil cylinder 2 16, which is fixedly mounted on the movable block 6. The oil cylinder 2 16 is connected to the oil cylinder 1 14 via a hose. A limit spring 18 is fixedly connected to the piston rod 2 17 at the front end of the oil cylinder 2 16. A movable block 19 is connected to the front end of the limit spring 18. The movable block 19 is slidably mounted on the back of the massage head 7.

[0038] The piston block 11 is moved by the rotating rod 13, which in turn changes the oil inside the first oil cylinder 14 and the second oil cylinder 16, thereby adjusting the squeezing force of the second oil cylinder 16 on the limit spring 18. This allows the elastic force applied by the limit spring 18 to the massage head 7 to be adjusted synchronously, enabling the device to adapt to the massage intensity of different muscle areas.

[0039] In one embodiment of the present invention, the vibration mechanism includes a mounting block 601, which is fixedly mounted on a movable block 6. A limiting block 602 is fixedly mounted on the mounting block 601 and is slidably mounted in a spiral groove 501. One side of the movable block 6 is set in an arc shape, and the arc-shaped side is located on the movement trajectory of the connecting plate 10.

[0040] As one embodiment of the present invention, the vibration mechanism further includes a deflection block 20, which is rotatably installed in the internal cavity of the moving block 6. A docking block 21 is rotatably installed on the deflection block 20, and a vibration block 22 is connected to the front end of the docking block 21. The vibration block 22 is connected to the back of the massage head 7 through a fixedly installed tension spring 23.

[0041] As one embodiment of the present invention, the vibration mechanism further includes a movable rod 24, which is fixedly mounted on the deflection block 20. A sliding block 2401 is fixedly mounted on the movable rod 24, and the movable rod 24 is slidably mounted in the cavity opened inside the connecting rod 5 by means of the sliding block 2401.

[0042] In one embodiment of the present invention, the lower end of the massage head 7 is provided with symmetrical arc-shaped protrusions 701, and the protrusions 701 are correspondingly arranged with the arc-shaped blocks on the abutment block 8.

[0043] The rotating rod 13 drives the rotating disk 12 to rotate, which in turn drives the piston block 11 to move under the action of the track groove 1201. This causes the piston block 11 to drive the connecting plate 10 to move up and down along the rotating bearing 9, thereby changing the movement distance of the connecting plate 10 pushing the moving block 6, and thus adjusting the movement trajectory of the massage head 7.

[0044] Working principle: The massage machine body 1 is placed on the user's massage position via the fixing strap 2. When massaging the back, the massage area is large and requires greater force. At this time, by rotating the rotating rod 13, the rotating rod 13 drives the rotating disk 12 to rotate synchronously. The rotating disk 12 is limited by the track groove 1201, which drives the piston block 11 to move the connecting plate 10 upward. At the same time, as the piston block 11 moves, the piston rod 15 moves synchronously, which squeezes the oil in the oil cylinder 14 and transmits it to the oil cylinder 16 through the infusion hose. As the oil in the oil cylinder 16 increases, the piston rod 17 in the oil cylinder 16 moves outward, squeezing the limiting spring 18 and compressing the limiting spring 18. This increases the pressure of the limiting spring 18 on the massage head 7, thereby increasing the vibration intensity of the massage head 7.

[0045] After adjustment, start the rotary motor 4. The rotary motor 4 drives the rotary bearing 9 to move. The rotary bearing 9 drives the connecting plate 10 to rotate synchronously. During the rotation of the connecting plate 10, it abuts against the moving block 6, pushing the moving block 6 to move to both sides. During the movement of the moving block 6, it contacts the spiral groove 501 on the connecting rod 5 through the docking block 21 on the deflection block 20, causing the connecting rod 5 to rotate. The connecting rod 5 drives the deflection block 20 to rotate through the movable rod 24. The deflection block 20 pulls the docking block 21 to move back and forth by rotating, so that the vibration block 22 abuts against the massage head 7 and vibrates through the tension spring 23.

[0046] Meanwhile, during the movement of the moving block 6, the protrusion 701 at the bottom of the massage head 7 continuously abuts against the abutting block 8, allowing the massage head 7 to move up and down continuously as the moving block 6 moves, thereby increasing the overall massage effect by making the massage head 7 swing up and down.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
