Description

Technical Field

[0001] The utility model relates to the technical field of eye care products, in particular to an eye massager. Background Art

[0002] With the adjustment of the social division of labor structure, more and more occupations require long hours of reading or processing document materials, resulting in an increasing burden on modern people's eyes. After a day's work, it is easy to have problems of eye fatigue. To promote blood circulation around the eyes and relieve eye fatigue, many eye massage products have emerged on the market.

[0003] Existing eye massage products generally wear close to the eye socket and use the reciprocating movement of the massage plate to cause the massage head connected to the massage plate to rub or push against the surface of the eye socket, thereby accelerating the blood flow rate around the eyes. However, since the massage head rubs against the skin tissue in a direction parallel to the surface of the eye socket, after frequent use of the product, the skin near the eyes that often comes into contact with the massage head is prone to wear problems. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an eye massager to solve the problem that the long-term friction of the massage head against the skin causes damage to the skin near the eyes.

[0005] An eye massager, comprising:

[0006] A housing;

[0007] A transmission mechanism, the transmission mechanism includes a crankshaft and a speed-regulating transmission component connected to the crankshaft; the crankshaft includes a positive shaft portion rotatably disposed in the housing and an eccentric shaft portion connected to the positive shaft portion; the included angle between the axial direction of the positive shaft portion and the axial direction of the eccentric shaft portion is the shaft included angle; the shaft included angle is within the range of 0 to 20 degrees;

[0008] A massage contact component, the massage contact component includes a massage substrate and a massage head connected to the massage substrate; one side of the massage substrate is movably connected to the housing; the massage substrate is rotatably connected to the eccentric shaft portion and rotates relative to the axis of the eccentric shaft portion; the included angle between the axial direction of the eccentric shaft portion and the massage substrate is fixed; the massage head has a plurality of convex grains; and

[0009] A driving mechanism, the driving mechanism drives the positive shaft portion to rotate through the speed-regulating transmission component.

[0010] The above-mentioned eye massager, the driving mechanism drives the positive shaft part to rotate through the speed-regulating transmission component, so that the positive shaft part rotates relative to the housing with its own axis as the rotation axis; since there is an angle between the eccentric shaft part and the positive shaft part, while the positive shaft part rotates, the eccentric shaft part rotates around the positive shaft part; due to the movable guiding connection relationship between the massage substrate and the housing, the massage substrate cannot rotate arbitrarily relative to the housing. When the eccentric shaft part rotates to different positions relative to the positive shaft part, since the axial direction of the eccentric shaft part and the massage substrate maintains a predetermined angle, the angle direction between the massage substrate and the positive shaft part is adjusted, so that the distances of different parts of the massage substrate relative to the housing change. The convex grains are distributed on the massage head in a shape close to the eye socket. During the continuous rotation of the crankshaft, the multiple convex grains connecting the same massage substrate successively approach and press into the periphery of the eye socket and exert a pressing effect on the corresponding parts of the eye socket. Any convex grain only moves in the direction of moving away from or approaching the corresponding eye socket part, and will not move parallel to the skin on the surface of the eye socket, thereby avoiding relative friction between the massage head and the skin near the eye socket and effectively reducing the problem of skin wear.

[0014] In one embodiment, the axes of each of the double-layer gears are arranged parallel to each other; the included angle between the axial direction of the positive shaft part of the crankshaft and the axes of the double-layer gears is in the range of 20 to 28 degrees; the output gear is a bevel gear; the double-layer gear meshing with the output gear has a layer of bevel teeth to mesh with the output gear; thereby further improving the use effect of the eye massager.

[0042] Please refer to Figures 1 to 12, the eye massager 100 of an embodiment of the present invention is used to provide massage to the eyes to relieve eye fatigue. The eye massager 100 includes: a housing 20, a transmission mechanism 30, a massage contact assembly 40 and a driving mechanism 50; the transmission mechanism 30 includes a crankshaft 31 and a speed regulation transmission assembly 32 connecting the crankshaft 31; the crankshaft 31 includes a positive shaft portion 311 rotatably disposed in the housing 20 and an eccentric shaft portion 312 connecting the positive shaft portion 311; the positive shaft portion 311 is rotatably connected to the housing 20; the included angle between the axial direction of the positive shaft portion 311 and the axial direction of the eccentric shaft portion 312 is the shaft included angle C; the shaft included angle C is in the range of 0 to 20 degrees; the massage contact assembly 40 includes a massage substrate 41 and a massage head 42 connected to the massage substrate 41; one side of the massage substrate 41 is movably connected to the housing 20; the massage substrate 41 is rotatably connected to the eccentric shaft portion 312 and rotates relative to the axis of the eccentric shaft portion 312; the included angle between the axial direction of the eccentric shaft portion 312 and the massage substrate 41 is fixed; the massage head 42 has a plurality of convex grains 421; the driving mechanism 50 drives the positive shaft portion 311 to rotate through the speed regulation transmission assembly 32.

[0043] The driving mechanism 50 drives the positive shaft portion 311 to rotate through the speed regulation transmission assembly 32, so that the positive shaft portion 311 rotates relative to the housing 20 with its own axis as the rotation axis; due to the included angle between the eccentric shaft portion 312 and the positive shaft portion 311, while the positive shaft portion 311 rotates, the eccentric shaft portion 312 rotates around the positive shaft portion 311; due to the existence of a movable guiding connection relationship between the massage substrate 41 and the housing 20, the massage substrate 41 cannot rotate arbitrarily relative to the housing 20. When the eccentric shaft portion 312 rotates to different positions relative to the positive shaft portion 311, since the included angle between the axial direction of the eccentric shaft portion 312 and the massage substrate 41 remains a predetermined angle, the included angle direction between the massage substrate 41 and the positive shaft portion 311 is adjusted, so that the distances of different parts of the massage substrate 41 relative to the housing 20 change. The convex grains 421 are distributed on the massage head 42 in a shape close to the eye socket. During the continuous rotation of the crankshaft 31, the multiple convex grains 421 connecting the same massage substrate 41 sequentially approach and press into the periphery of the eye socket and generate a pressing effect on the corresponding part of the eye socket. Any convex grain 421 only moves in the direction of moving away from or approaching the corresponding part of the eye socket, and does not move parallel to the skin on the surface of the eye socket, thereby avoiding relative friction between the massage head 42 and the skin near the eye socket and effectively reducing the problem of skin wear.

[0044] Specifically, when the convex grains 421 in one area of the massage head 42 are in contact with the eye socket, the convex grains 421 in other areas of the massage head 42 are separated from the eye socket, and according to the rotation direction of the crankshaft 31, the convex grains 421 that are generating a pressing effect on the eye socket are cycled alternately.

[0045] Please refer to Figure 2, in one of the embodiments, the transmission mechanism 30 and the massage contact components 40 are respectively arranged in pairs; the driving mechanism 50 provides a driving effect on each transmission mechanism 30 respectively; the massage substrates 41 of different massage contact components 40 are symmetrically arranged. By arranging the paired transmission mechanism 30 and massage contact components 40, the driving mechanism 50 can drive two symmetrical massage substrates 41 to swing simultaneously, so that massage care can be realized for both eyes at the same time, improving the use experience of the eye massager 100.

[0046] Specifically, the massage head 42 includes a soft sleeve 422 with a plurality of convex grains 421 connected to one side, and an opening 423 is provided on the other side of the soft sleeve 422 to sleeved the soft sleeve 422 onto the massage substrate 41 through the opening 423, so as to improve the assembly efficiency of the eye massager 100 and facilitate the user to replace the massage head 42.

[0047] Please refer to Figure 7 and Figure 8 , in one of the embodiments, the massage substrate 41 includes a main board portion 411 and a side board portion 412 connected in sequence; the main board portion 411 and the side board portion 412 are arc-shaped or a predetermined angle is formed between the main board portion 411 and the side board portion 412 to adapt to the contour near the eyes.

[0048] The edge shape of the main board portion 411 corresponds to the contour of the eye socket, and the convex grains 421 on the massage head 42 close to the main board portion 411 are used to press on the upper side, lower side of the eye socket, or the intersection between the eye socket and the nose bridge, which can stimulate the relevant acupoints near the eye socket; through the overall bending of the massage substrate 41 or the bending of the side board portion 412 relative to the main board portion 411, the convex grains 421 on the massage head 42 close to the side board portion 412 are used to massage the temple, so that more acupoints can be stimulated by adjusting the shape of the massage substrate 41. Specifically, the axis of the eccentric portion 312 passes through the main board portion 411 to reduce the volume of the eye massager 100.

[0049] Please refer to Figure 4 and Figure 5 , in one of the embodiments, the driving mechanism 50 includes a driving motor 51 and a worm 52 connected to the output shaft of the driving motor 51; an output gear 314 is fixedly sleeved on the positive shaft portion 311 of the crankshaft 31; the speed regulation transmission component 32 includes at least two double-layer gears 321, and the double-layer gears 321 play a role of decelerating and transmitting in the direction from the worm 52 to the output gear 314.

[0050] When the driving motor 51 drives the worm 52 to rotate along its own axis, since at least one double-layer gear 321 is arranged between the worm 52 and each output gear 314, the worm 52 meshes with the double-layer gears 321 on both sides respectively, so as to drive two crankshafts 31 to rotate simultaneously; specifically, in combination with Figure 4 andFigure 9 As shown, to increase the reduction ratio, multiple double-layer gears 321 are provided between the worm 52 and any output gear 314. The multiple double-layer gears 321 are configured in a decelerating transmission form in the direction from the worm 52 to the output gear 314; the double-layer gear 321 meshing with the worm 52 has a layer of helical teeth meshing with the worm 52; through the decelerating effect of the double-layer gear 321, the swinging speed of the massage substrate 41 can be reduced, making the yaw of the massage substrate 41 and the massage head 42 more stable. In other embodiments, the worm 52 can also drive the output gear 314 in the form of a transmission shaft or the like. Specifically, the drive motor 51 is a micro DC motor.

[0051] Please refer to Figure 5 and Figure 9 , in one of the embodiments, the axes of the double-layer gears 321 are arranged parallel to each other; the axial angle B between the axial direction of the positive shaft portion 311 of the crankshaft 31 and the axis of the double-layer gear 321 is in the range of 20 to 28 degrees; the output gear 314 is a bevel gear; the double-layer gear 321 meshing with the output gear 314 has a layer of bevel teeth to mesh with the output gear 314.

[0052] By making the axial direction of the positive shaft portion 311 form a predetermined angle B with the axis of the double-layer gear 321, the yaw axis and the swinging range of the massage substrate 41 are adjusted, which can adapt to the contour change between the front of the eye socket and the temple, so that the moving range of the massage substrate 41 and the massage head 42 can cover the front of the eye socket and the temple, further improving the use effect of the eye massager 100. Preferably, the axial angle B between the axial direction of the positive shaft portion 311 of the crankshaft 31 and the axis of the double-layer gear 321 is 24 degrees.

[0053] Please refer to Figure 3 , Figure 4 , Figure 11A and Figure 11B , in one of the embodiments, the housing 20 includes a speed regulation box 21 and a bracket 22 connecting the speed regulation box 21; the positive shaft portion 311 is rotatably connected to the speed regulation box 21; the drive mechanism 50 and the speed regulation transmission assembly 32 are accommodated in the speed regulation box 21; the massage substrate 41 is movably connected to the bracket 22; the eccentric shaft portion 312 passes through the bracket 22 and is rotatably connected to the massage substrate 41.

[0054] By accommodating the drive mechanism 50 and the speed regulation transmission assembly 32 in the speed regulation box 21, a protective effect can be exerted on the drive mechanism 50 and the speed regulation transmission assembly 32; the crankshaft 31, the speed regulation transmission assembly 32, the drive mechanism 50, etc. form an integral body through the speed regulation box 21, which is conducive to the modular assembly of the eye massager 100 and is conducive to improving the assembly efficiency of the eye massager 100. Specifically, the speed regulation box 21 includes an inner housing member 211 connecting the bracket 22 and an outer housing member 212 connecting the inner housing member 211.

[0055] See also Figure 11A and Figure 11B A first bearing member 315 is sleeved on the positive shaft portion 311 , and the first bearing member 315 is accommodated in the speed regulating box 21 to reduce the friction between the positive shaft portion 311 and the speed regulating box 21 .

[0056] See also Figure 6A , Figure 6B and Figure 7 In one embodiment, a guide block 221 is provided on the side of the bracket 22 facing the massage base plate 41, and an inner guide groove 222 is provided in the guide block 221; the guide block 221 also has an outer guide groove 223 connecting the outer side of the guide block 221 and the inner guide groove 222; a support rod 413 is connected to the side of the massage base plate 41 facing the bracket 22, and the support rod 413 is connected to a spherical block 414, the spherical block 414 is accommodated in the inner guide groove 222, and the support rod 413 is penetrated in the outer guide groove 223; the width of the outer guide groove 223 is greater than the diameter of the support rod 413, and smaller than the diameter of the spherical block 414.

[0057] Since the spherical block 414 is connected to the massage base plate 41 through the support rod 413, after the spherical block 414 is accommodated in the inner guide groove 222, due to the width limitation of the outer guide groove 223, the spherical block 414 can only move within the plane range, straight line range or curve range defined by the inner guide groove 222, and cannot be separated from the guide block 221, so the angle range of the massage base plate 41 relative to the bracket 22 can be limited to prevent the massage base plate 41 from completely rotating with the crankshaft 31; since the width of the outer guide groove 223 is greater than the diameter of the support rod 413, through the gap between the support rod 413 and the guide block 221, the support rod 413 also has a certain swing range in the direction perpendicular to the outer guide groove 223, so that the position change of the massage base plate 41 caused by the swing of the eccentric part 312 can be fully adapted. Specifically, the guide block 221 is provided with an inlet 224 connected to the inner guide groove 222 at a position close to the bracket 22, so that the spherical block 414 can enter the inner guide groove 222.

[0058] See also Figure 7 , Figure 8 , Figure 11A and Figure 11B In one embodiment, a shaft seat 415 is connected to the side of the massage base plate 41 facing away from the protrusion 421 ; a movable bearing member 316 is sleeved on the eccentric portion 312 ; and an outer ring of the movable bearing member 316 is connected to the shaft seat 415 or accommodated in the shaft seat 415 .

[0059] By providing a movable bearing member 316 between the off-axis portion 312 and the shaft seat 415, the friction between the off-axis portion 312 and the massage substrate 41 can be reduced, thereby extending the service life of the eye massager 100. Further, to prevent the shaft seat 415 from detaching from the off-axis portion 312, the shaft seat 415 is disposed on the side of the massage substrate 41 close to the bracket 22, and the insertion groove 416 of the shaft seat 415 is disposed on the side of the massage substrate 41 facing away from the bracket 22. After the movable bearing member 316 is received in the shaft seat 415, the off-axis portion 312 passes through the bracket 22 and penetrates into the inner ring of the movable bearing member 316. One end of the off-axis portion 312 is locked relative to the inner ring of the movable bearing member 316 by a screw member, and then the cover plate 417 is used to abut against the insertion groove 416 of the shaft seat 415 to confine the movable bearing member 316 in the shaft seat 415. Therefore, detachment of the off-axis portion 312 from the shaft seat 415 and detachment of the off-axis portion 312 from the movable bearing member 316 can be avoided.

[0060] Please refer to Figure 1 and Figure 3 , in one of the embodiments, the eye massager 100 further includes an energy storage member 60 connected to the drive mechanism 50 and a control board 70 connected to the drive mechanism 50; the energy storage member 60 is used to supply electrical energy to the drive mechanism 50; the control board 70 is used to adjust the operating state of the drive mechanism 50. Therefore, the limitation of the power cord can be eliminated, and the convenience of using the eye massager 100 can be improved. Specifically, the energy storage member 60 is a battery cell and is mounted on the bracket 22; the control board 70 has a control circuit connected to the drive motor 51, and the control circuit adjusts the massage frequency of the massage substrate 41 and the massage head 42 by controlling the rotation speed of the output shaft of the drive motor 51 to meet the usage needs of different users.

[0061] Please refer to Figure 12 , in one of the embodiments, the shaft angle C is in the range of 4 to 8 degrees; the axis of the off-axis portion 312 is on one side of the straight line passing through the axis of the on-axis portion 311. During the rotation of the off-axis portion 312 around the axis of the on-axis portion 311, the end face of the off-axis portion 312 away from the on-axis portion 311 forms a concave conical surface trajectory by rotation. Since the angle of the off-axis portion 312 relative to the massage substrate 41 in the axial direction remains stable, during the rotation of the off-axis portion 312, the massage substrate 41 and the massage head 42 can fully adapt to the contour characteristics near the eye socket, providing a good massage effect. Specifically, the shaft angle C is 4 degrees.

[0062] In this embodiment, the driving mechanism 50 drives the rotation of the positive shaft portion 311 through the speed-regulating transmission assembly 32, so that the positive shaft portion 311 rotates relative to the housing 20 with its own axis as the rotation axis; since there is an angle between the eccentric shaft portion 312 and the positive shaft portion 311, while the positive shaft portion 311 rotates, the eccentric shaft portion 312 rotates around the positive shaft portion 311; due to the movable connection relationship between the massage substrate 41 and the housing 20, the massage substrate 41 cannot rotate arbitrarily relative to the housing 20. When the eccentric shaft portion 312 rotates to different positions relative to the positive shaft portion 311, since a predetermined angle is maintained between the axial direction of the eccentric shaft portion 312 and the massage substrate 41, the angular direction between the massage substrate 41 and the positive shaft portion 311 is adjusted, so that the distances of different parts of the massage substrate 41 relative to the housing 20 change. The convex grains 421 are distributed on the massage head 42 in a shape close to the eye socket. During the continuous rotation of the crankshaft 31, the multiple convex grains 421 connecting the same massage substrate 41 sequentially approach the eye socket and exert a pressing effect on the corresponding part of the eye socket. Any convex grain 421 only moves in the direction of moving away from or approaching the corresponding part of the eye socket, but does not move parallel to the skin on the surface of the eye socket, thus avoiding relative friction between the massage head 42 and the skin near the eye socket and effectively reducing the problem of skin abrasion.
