TECHNICAL FIELD

[0001] The utility model relates to massager structure field, especially a swing type massager. BACKGROUND

[0002] As a common appliance for eliminating fatigue and entertainment relaxation in life, the massager is more and more welcomed by the market, and has a strong market growth trend.

[0003] At present, most of the massagers press the body in the form of vibration or swing through the massage head to achieve the purpose of massage. In order to improve the comfort of body touch, the massager often uses a flexible shell as an outer shell, or uses a soft shell to wrap on the outer shell, and the massage head is arranged on the inner side of the flexible shell. The massage head indirectly contacts the body through the flexible shell. Whenever the massage head vibrates or swings inside the massager, the massage head transmits the massage pressure through the flexible shell. However, the vibration or swing amplitude generated by the massage head built in the massager is restricted by the internal space of the massager, and cannot generate a large sensing force and depth. In addition, the massage head in the massager is rigidly connected to the driving assembly, so that the massage head generates rigid vibration or swing under the driving of the driving assembly. Under the action of high frequency for a long time, it is easy to cause damage to the muscles and soft tissues of the contact part. SUMMARY

[0004] The utility model aims at providing a swing type massager, which can increase the sensing force and depth of the massage head on the massager, and avoid rigid action of the massage head to protect the muscles and soft tissues of the contact part.

A swing part is arranged on the outer side of the deformation part, and a guide column is arranged on the inner side of the deformation part. A driving assembly is arranged in the shell opposite to the guide column, and an eccentric shaft is arranged on the driving assembly. The driving assembly is used for driving the eccentric shaft to rotate around the guide column. The eccentric shaft is in contact with the side surface of the guide column to press the guide column to incline.

[0006] In the swing type massager, the guide column and the flexible shell are integrally formed. The diameter value of the guide column is greater than the thickness value of the deformation part.

[0007] In the swing type massager, the ratio of the diameter value of the guide column to the thickness value of the deformation part is in the range of 2:1 to 10:1.

[0009] In the swing-type massager, the guide column is arranged at the shaft center of the swing hole; and the swing part is arranged at the shaft center of the swing hole.

[0010] In the swing-type massager, the eccentric shaft is arranged in parallel with the guide column; the eccentric shaft is provided with a tapered part, the thin end of the tapered part is arranged towards the deformation part, and the eccentric shaft abuts against the guide column through the tapered part.

[0011] In the swing-type massager, the outside of the flexible sleeve is further provided with a first massage head; the shell is further provided with an eccentric sleeve connected to the driving assembly and a swing rod flexibly connected to the eccentric sleeve; the driving assembly is further used for driving the eccentric sleeve to rotate around the rotation axis of the eccentric sleeve; and the swing rod extends and is inserted into the first massage head.

[0012] In the swing-type massager, the middle part of the swing rod is flexibly connected to the shell.

[0013] In the swing-type massager, the driving assembly is provided with a primary power output end and a secondary power output end; the first power output end is connected to the eccentric shaft; and the second power output end is connected to the eccentric sleeve.

[0015] After the above technical scheme is adopted, the swing-type massager has the following beneficial effects:

[0016] The technical scheme is characterized in that the swinging part is arranged on the outer surface of the flexible shell cover, which is equivalent to externally arranging the massager outside the massager, avoids being restricted by the internal space of the massager, and has a relatively large swinging range, wherein the driving assembly of the massager is located on the inner side of the flexible shell cover, the swinging part is located on the outer side of the flexible shell cover, and is not rigidly connected with the driving assembly in the shell, but is flexibly connected with the driving assembly through the guide column, the eccentric shaft is arranged on the driving assembly, the eccentric shaft presses the guide block to incline, the guide column on the flexible shell cover is located on the deformation part corresponding to the swinging hole, the guide column inclines, drives the deformation part to twist and deform, the swinging part also deviates from the initial position and is located on the deformation part, when the eccentric shaft rotates around the guide column under the driving of the driving assembly, the direction in which the eccentric shaft presses the guide column to incline changes continuously, the deformation part twists and deforms correspondingly, and the swinging part swings under the continuous deformation of the deformation part to generate a massaging effect, since the twisting of the deformation part is elastic deformation, when the swinging part collides with the body, the deformation part can internally digest part of kinetic energy, when the resistance becomes large, the deformation part can also drive the swinging part to retract reversely, so that the swinging part is a flexible motion in the whole process, rigid hammering of the body is avoided, the sensing force and depth of the massaging head on the massager are increased, and rigid motion of the massaging head is avoided to protect muscles and soft tissues of the contact part.

[0022] The technical scheme of the utility model will be further explained in detail in combination with specific implementation manners, but does not constitute any limitation to the utility model.

[0023] Embodiment 1:

[0024] In combination with Figure 1 andFigure 2 As shown, the swinging massage device comprises a shell 5 and a flexible shell cover 1 wrapped on the outer surface of the shell 5, the shell 5 is provided with a swinging hole, the flexible shell cover 1 is provided with a deformation part 14 opposite to the swinging hole, the deformation part 14 is provided with a swinging part 11 on the outer side and a guide column 15 on the inner side, the shell 5 is provided with a driving assembly 4 opposite to the guide column 15 and an eccentric shaft 2 arranged on the driving assembly 4, the driving assembly 4 is used to drive the eccentric shaft 2 to rotate around the guide column 15, and the eccentric shaft 2 is in contact with the side of the guide column 15 to press the guide column 15 to tilt.

[0025] Specifically, the swinging part 11 is arranged on the outer surface of the flexible shell cover 1, which is equivalent to arranging the massage device outside the massage device, avoiding the restriction of the internal space of the massage device, so that the swinging part 11 has a relatively large swinging range, wherein the driving assembly 4 of the massage device is located on the inner side of the flexible shell cover 1, the swinging part 11 is located on the outer side of the flexible shell cover 1 and is not rigidly connected with the driving assembly 4 in the shell 5, but is flexibly connected with the driving assembly 4 through the guide column 15, the eccentric shaft 2 is arranged on the driving assembly 4, the eccentric shaft 2 is in contact with the guide block to press the guide block to tilt, the guide column 15 on the flexible shell cover 1 is located on the deformation part 14 corresponding to the swinging hole, the guide column 15 tilts to drive the deformation part 14 to twist and deform, the swinging part 11 also deviates from the initial position, when the eccentric shaft 2 rotates around the guide column 15 under the driving of the driving assembly 4, the direction of the eccentric shaft 2 pressing the guide column 15 to tilt changes constantly, the deformation part 14 twists and deforms correspondingly, and the swinging part 11 swings under the constant deformation of the deformation part 14 to produce a massage effect, since the deformation part 14 twists and deforms elastically, when the swinging part 11 collides with the body, the deformation part 14 can internally digest part of the kinetic energy, when the resistance increases, the deformation part 14 can also drive the swinging part 11 to retract reversely, so that the swinging part 11 is flexible throughout the process, avoiding rigidly hitting the body, realizing increasing the sensing force and depth of the massage head on the massage device, and avoiding rigid action of the massage head to protect the muscles and soft tissues of the contact part.

[0026] In actual application, when the guide column 15 tilts, the axis of the guide column 15 changes or deforms, so that the guide column 15 is in a linear inclined state or a state of bending deformation, and the guide column 15 can be a soft component or a hard component, which is not limited in the embodiment.

[0027] Preferably, the guide column 15 is integrally formed with the flexible shell cover 1, and the diameter of the guide column 15 is greater than the thickness of the deformation part 14.

[0028] The guide column 15 is integrally formed with the flexible shell 1, avoiding production preparation and assembly process for the guide column 15, reducing production time and production cost; and the diameter of the guide column 15 is greater than the thickness of the deformation part 14, so that the strength of the guide column 15 is greater than that of the deformation part 14, avoiding deformation of the guide column 15 and failure to drive the deformation part 14 to deform.

[0029] Further preferably, the swing part 11 is integrally formed with the flexible shell 1, i.e. the swing part 11 is also made of flexible material, so that the swing part 11 can also absorb part of the impact through elastic deformation, and the touch feeling when contacting the body is softer, avoiding injury to muscles and soft tissues while improving comfort; similarly, in the production stage, production preparation and assembly process for the swing part 11 are avoided, reducing production time and production cost; in addition, the swing part 11 can be assembled on the deformation part 14 as a soft or hard component, which is not limited in the embodiment.

[0030] In specific implementation, the ratio of the diameter of the guide column 15 to the thickness of the deformation part 14 ranges from 2:1 to 10:1.

[0031] The ratio of the diameter of the guide column 15 to the thickness of the deformation part 14 is set so that the guide column 15 can still drive the deformation part 14 to deform after deformation, while avoiding affecting the processing quality in the integrated molding due to the excessive ratio, such as avoiding uneven solidification shrinkage of the swing part 11 and the deformation part 14, so as to avoid defects such as pores, cracks and deformation, and reduce internal stress concentration; in addition, the diameter of the guide column 15 is limited under the restriction of the deformation part 14, avoiding increasing the volume of the massager, and the deformation part 14 is always in a relatively thin state under the restriction of the guide column 15, and can produce torsional deformation without requiring much energy.

[0032] Further preferably, the deformation part 14 has a blind hole structure; the deformation part 14 is clamped inside the swing hole and opens to the outside of the flexible shell 1; the swing part 11 is arranged on the inner cavity side of the bottom of the deformation part 14 and extends to the outside of the flexible shell 1; and the guide column 15 is arranged on the outer surface side of the bottom of the deformation part 14.

[0033] The structure of the deformation part 14 is set so that the corner positions of the deformation part 14 all become the fulcrums of torsional deformation, such as the intersection corner between the bottom and the side of the deformation part 14 and the intersection corner between the side of the deformation part 14 and the non-deformation part 14; compared with the flat deformation part 14, the deformation part 14 with the blind hole structure has more fulcrums of torsional deformation, increasing the action amplitude of torsional deformation and reducing the difficulty of torsional deformation.

[0034] Preferably, the guide column 15 is arranged at the axis of the swing hole; and the swing part 11 is arranged at the axis of the swing hole.

[0035] The guide column 15 is arranged at the shaft center of the swing hole, so that the guide column 15 is located at the center of the deformation part 14. When the guide column 15 drives the deformation part 14 to be distorted, the distortion of the deformation part 14 spreads uniformly from the center to the periphery, so that the movement of the deformation part 14 and the swing part 11 is more regular and controllable. Similarly, the guide column 15 is arranged at the shaft center of the swing hole, so that the movement of the swing part 11 is more regular and controllable, and the swing part 11 can swing at a uniform speed, so that the massage pressure is not irregularly large or small, and the massage effect and the use experience are enhanced.

[0036] In the preferred embodiment, the eccentric shaft 2 is arranged in parallel with the guide column 15, the eccentric shaft 2 is provided with a tapered part 21, the thin end of the tapered part 21 is arranged towards the deformation part 14, and the eccentric shaft 2 abuts against the guide column 15 through the tapered part 21.

[0037] The eccentric shaft 2 is arranged in parallel with the guide column 15, so that the eccentric shaft 2 abuts against the guide column 15 in a direction perpendicular to the guide column 15 or inclined relative to the guide column 15. In the transverse direction of the massager, the width of the massager is reduced, and the volume of the massager is reduced. Correspondingly, the contact area and the contact angle between the eccentric shaft 2 and the guide column 15 are relatively small. By arranging the tapered part 21 on the eccentric shaft 2 and contacting the guide column 15 through the tapered surface of the tapered part 21, the contact area between the eccentric shaft 2 and the guide column 15 is increased, and the contact angle is increased under the guidance of the slope of the tapered surface, so that the component force of the eccentric shaft 2 applied to the guide column 15 in the width direction of the massager is increased, and the effect of causing the guide column 15 to tilt is enhanced.

[0038] In actual application, the tapered part 21 can be an independent component assembled with the eccentric shaft 2, or can be an inverted bevel structure on the eccentric shaft 2. The present embodiment does not make too many limitations on this. When the tapered part 21 is an independent component, the eccentric shaft 2 can be replaced with tapered parts 21 of different tapered surface slopes, so as to adjust the contact angle between the eccentric shaft 2 and the guide column 15, and make the swing part 11 have multiple swing effects which can be set according to the tapered surface slope. When the tapered part 21 is an inverted bevel structure, the production of materials and the assembly process for the tapered part 21 are omitted, so as to reduce the production time and the production cost.

[0039] The swing part 11 can be a pendulum in the shape of a hammer or a mallet, can be a soft plate or a soft sheet, or can be a swing rod, and the present embodiment does not make too many limitations on this.
