Description

A massager Technical Field

[0001] The present invention relates to the technical field of massage therapy, in particular to a massage instrument. Background Art

[0002] With the accelerated pace of people's lives and work, especially for office workers who sit for long periods of time, health problems such as shoulder and neck pain often occur. Currently, massagers appearing on the market can massage the shoulders and neck and other parts of the body, effectively relieving people's physical fatigue, improving sleep quality, and also greatly helping to maintain a good physical condition for healthy people.

[0003] For example, Chinese patent application number CN201510924022.1 discloses a massager, which includes a main body, a rotating shaft extending and rotating on the main body in a horizontal direction, a driving mechanism for driving the rotating shaft to rotate, and a positioning mechanism for positioning the rotating shaft. Kneading devices are symmetrically arranged on the left and right sides of the rotating shaft, and the kneading devices include a first eccentric wheel, a second eccentric wheel and a third eccentric wheel, an L-shaped first kneading frame arranged between the first eccentric wheel and the second eccentric wheel, and a second kneading frame sleeved on the third eccentric wheel. The second kneading frame is tilted toward the center of the rotating shaft, the first eccentric wheel, the second eccentric wheel and the third eccentric wheel are fixedly connected, and a limiting mechanism is arranged between the first eccentric wheel and the rotating shaft. A kneading block is fixedly arranged at the other end of the first kneading frame, and a kneading wheel is rotatably arranged at the other end of the second kneading frame, which can complete 3D movements of acupressure and kneading through the same motor.

[0004] In the aforementioned patent, the left and right kneading components are connected by a rotating shaft, on which a worm gear is mounted. The motor drives the shaft through the worm gear. However, because the worm gear driven by the motor is arranged longitudinally (the axis of the worm gear coincides with the axis of the rotating shaft), it occupies space within the main body, preventing further reduction in the size of the massager, making it inconvenient to carry. Technical issues

[0005] The technical problem to be solved by the present invention is to provide a massager that can form an air-avoidance area between two massage components for placing batteries or circuit boards, rationally utilizing the space inside the massager, thereby reducing the size of the massager and making it easier to carry.

[0012] When the driving assembly rotates forward, the pin shaft pushes the cam and the cam on the other side to rotate in a mirror-image manner through the pushing portion. When the driving assembly rotates reversely, after the pin shaft rotates to the other side, the pin shaft pushes the cam and the cam on the other side to move in a non-mirror-image manner through the pushing portion.

[0013] Furthermore, the drive assembly includes a single-axis motor, the output end of the single-axis motor is connected to a first worm, the outer wall of the first worm is meshedly connected to two first worm wheels, the two first worm wheels are respectively located on both sides of the first worm, and the axis of each first worm wheel coincides with the axis of the corresponding active bevel gear, and the active bevel gear is installed on the top of the corresponding first worm wheel, and the first worm wheel and the active bevel gear are integrally formed or fixed in combination.

[0014] Furthermore, the drive assembly includes a dual-axis motor, both ends of the dual-axis motor are respectively connected to a second worm, the outer wall of each second worm is meshedly connected to a second worm wheel, the bottom of the second worm wheel is connected to a driving gear, the outer wall of the driving gear is meshedly connected to a driven gear, the axis of the driven gear coincides with the axis of the driving bevel gear, and the driving bevel gear is installed on the top of the driven gear, and the driving bevel gear and the driven gear are integrally formed or fixed in combination.

[0019] Furthermore, each of the limiting components includes a fixing pin, which is connected to the shell through a mounting base. Each of the second massage arms is provided with an arc groove that matches the fixing pin. The fixing pin is slidably connected to the arc groove, and the fixing pin passes through the arc groove to constrain the movement trajectory of the second massage arm.

[0020] The advantages of the present invention are:

[0021] 1. The present invention utilizes two sets of bevel gears to create a clearing between the two massage components.

[0041] Referring to Figures 1 to 11, the present invention provides a massager, comprising a housing 1 and two symmetrically arranged massage components 2, each of which comprises a rotating shaft 21, with connecting seats 22 provided at both ends thereof, the connecting seats 22 being mounted on the housing 1, a driven bevel gear 23 being sleeved on the rotating shaft 21, the driven bevel gear 23 being coaxial with the rotating shaft 21, the driven bevel gear 23 being meshedly connected with a driving bevel gear 24, the bottom of the driving bevel gear 24 being connected to a driving component 3 for driving the driving bevel gear 24 to rotate, a clearing area 4 for placing a battery 6 or a circuit board 7 being formed between the two massage components 2, the clearing area 4 being located above the driving component 3;

[0042] The shell 1 is composed of a bottom shell 12, a transmission group lower shell 13, a transmission group upper shell 14, a guide block 15, an isolation layer 16 and a mask 17; the transmission group upper shell 14 and the transmission group lower shell 13 are respectively arranged on the upper and lower sides of the drive component 3 and contain the drive component 3; the two massage components 2 and the guide block 15 are installed in the installation position set on the transmission group upper shell 14, and the isolation layer 16 is set above the transmission group upper shell 14 and is located between the two massage components 2. In order to facilitate the subsequent maintenance and replacement of the battery 6, it is preferred that the battery 6 is placed in the airproof area 4, and the circuit board 7 is set between the transmission group lower shell 13 and the bottom shell 12. The isolation layer 16 provides support for the battery 6 and is further separated from the drive component 3 to reduce the heat generated by the drive component 3 from being transferred to the battery 6. The mask 17 is used to cover and fix the battery 6.

[0043] The rotating shaft 21 is also provided with an eccentric wheel group 25. When the rotating shaft 21 rotates, the rotating shaft 21 drives the eccentric wheel group 25 to rotate. Each of the massage components also includes a first massage arm 26 and an L-shaped second massage arm 27. The length of the second massage arm 27 is set according to the massage method. A boss 261 is provided at the bottom of the first massage arm 26. A long slot 11 is provided inside the shell 1. The long slot 11 is provided on the guide block 15. The eccentric wheel group 25 drives the first massage arm 26 to swing back and forth, so that the boss 261 slides in the long slot 11. The eccentric wheel group 25 drives the second massage arm 27 to perform reciprocating swing arm motion in the vertical direction, and two limit assemblies 5 for constraining the vertical motion trajectory of the second massage arm 27 are connected to the outside of the shell 1. The kneading effect of the massager is achieved through the respective movements of the first massage arm 26 and the second massage arm 27.

[0044] A first massage head 28 is connected to the end of the first massage arm 26, and a second massage head 29 is connected to the end of the second massage arm 27. The second massage head 29 can be integrally formed with the second massage arm, or the second massage head 29 can be replaced with a massage head of a different shape, size, or material hardness to suit the massage force requirements of different users, or the second massage head 29 can be used to massage other parts of the body after being replaced.

[0045] Specifically, the eccentric wheel assembly 25 includes a cam 251, an angular eccentric wheel 252, and an angular eccentric wheel cover 253. The eccentric wheel assembly 25 can be formed by integrally forming the cam 251, the angular eccentric wheel 252, and the angular eccentric wheel cover 253, or can be formed by connecting the cam 251, the angular eccentric wheel 252, and the angular eccentric wheel cover 253 as separate parts. One end of the second massage arm 27 is sleeved on the cam 251. When the rotating shaft 21 drives the cam 251 to rotate, the second massage arm 27 performs a reciprocating swinging arm motion in the vertical direction. The angular eccentric wheel 252 includes a first inclined portion 2521 having an inclined surface and a fitting portion 2522 connected to the first inclined portion 2521. The inclined surface of the first inclined portion 2521 forms an angle β with the axis of the rotating shaft 21. The value of β is selected according to actual conditions. The first inclined portion 2521 and the interlocking portion 2522 are integrally formed. One end of the first massage arm 26 is sleeved onto the interlocking portion 2522, which is fixedly connected to the angular eccentric wheel cover 253. The cam and angular eccentric wheel of the eccentric wheel assembly are integrally formed or fixed together. The driven bevel gear and cam are fixedly connected or integrally formed. When the rotating shaft 21 drives the angular eccentric wheel 252 to rotate, the first massage arm 26 swings back and forth.

[0046] Specifically, one side of the rotating shaft 21 is provided with a pin 211, the axis of which is perpendicular to the axis of the rotating shaft 21. A receiving groove 2511 for accommodating the pin 211 is provided on the side of the cam 251 near the driven bevel gear 23. The cam 251 and the rotating shaft 21 on which the pin 211 is mounted are located on the same side of the massager, meaning that the cam 251 and the rotating shaft 21 on which the pin 211 is mounted are components of the same massage assembly 2. A pusher 2512 is connected to the inner cavity of the receiving groove 2511. When the drive assembly 3 drives the eccentric wheel assembly 25 to rotate, the pin 211 contacts the pusher 2512, and the contact area between the pusher 2512 and the pin is a flat surface. In this application, forward rotation of the drive assembly 3 causing the two first massage arms 26 to simultaneously approach or move away from each other is defined as asynchronous motion, and reverse rotation of the drive assembly 3 causing the two first massage arms 26 to simultaneously swing to one side is defined as synchronous motion.

[0047] During asynchronous motion, the drive assembly 3 rotates forward, and the cams 251 in the two massage assemblies 2 rotate simultaneously. Since the pin shaft 211 is in contact with the pushing portion 2512 at this time, and the rotational torque of the rotating shaft 21 can be transmitted to the pushing portion 2512 at the contact position between the pin shaft 211 and the pushing portion 2512 to push the cam 251 to rotate, and the rotation of the cam 251 is a mirror image of the cam 251 on the other side, realizing the mirror image movement of the left and right massage assemblies 2, that is, the left and right first massage arms 26 approach or move away from each other at the same time, and the two second massage arms 27 swing on the vertical plane at the same time, and the two second massage arms 27 move completely synchronously, realizing the kneading function of the massager.

[0048] During synchronous motion, the driving assembly 3 reverses, and the rotating shafts 21 in the two massage assemblies 2 rotate at the same time. At this time, one of the cams 251 without the accommodating groove 2511 rotates along with the rotating shaft 21, while the other rotating shaft 21 equipped with the pin 211 rotates idly (that is, it does not drive the cam 251 connected to it to rotate). The contacting pin 211 and the pushing part 2512 are first separated. At this time, the rotating shaft rotates idly and the eccentric wheel group does not rotate. When the pin 211 rotates to the other side, that is, after the rotating shaft 21 rotates by a preset angle, which can be 180 degrees, the pin 211 contacts the pushing part 2512 again. At this time, the rotational torque of the rotating shaft 21 can be transmitted to the pushing part 2512 to push the cam 251 to rotate. The pin 211 pushes the cam 251 on the other side through the pushing part 2512, and the cam 251 on the other side does not rotate in a mirror image. That is, the rotation angles of the two eccentric wheel groups 25 differ by 180 degrees. At this time, the two first massage arms 26 move synchronously, that is, the two first massage arms 26 swing to one side at the same time, and the two first massage arms 26 swing at the same angle at any time, causing the human head to swing left and right, thereby easing the meridians and activating the joints. When the two cams 251 rotate synchronously, the two second massage arms 27 move asynchronously. In this case, the second massage arms 27 do not provide a particularly good user experience. In this case, to further improve the user experience, the second massage arms 27 can be removed, and the human head can be swung left and right by relying solely on the two first massage arms 26.

[0049] Generally speaking, the drive assembly 3 of this massager is driven by a motor that drives a worm, which in turn drives a horizontally mounted worm gear, which in turn drives the transmission assembly, thereby rotating the rotating shaft 21. This allows the first massage arm 26 and the second massage arm 27 to achieve a kneading effect, and also forms an air gap 4 between the two massage assemblies 2. The term "horizontally" in this application means that the end face of the worm gear is parallel to the axis of the rotating shaft 21 as shown in Figures 2 or 4.

[0050] The driving assembly 3 of this massager has two structures:

[0051] The first one:

[0052] The drive assembly 3 includes a single-axis motor 31, the output end of which is connected to a first worm 32, and the outer wall of the first worm 32 is meshed with two first worm wheels 33, the two first worm wheels 33 are respectively located on both sides of the first worm 32, and the axis of each first worm wheel 33 coincides with the axis of the corresponding driving bevel gear 24, and the driving bevel gear 24 is installed on the top of the corresponding first worm wheel 33.

[0053] The first worm gear 33 and the driving bevel gear 24 can be integrally formed or fixed together.

[0054] The second type:

[0055] The drive assembly 3 includes a dual-axis motor 34, and the two ends of the dual-axis motor 34 are respectively connected to a second worm 35. The outer wall of each second worm 35 is meshedly connected to a second worm wheel 36. The bottom of the second worm wheel 36 is connected to a driving gear 37. The outer wall of the driving gear 37 is meshedly connected to a driven gear 38. The axis of the driven gear 38 coincides with the axis of the driving bevel gear 24, and the driving bevel gear 24 is installed on the top of the driven gear 38.

[0056] The driving bevel gear 24 and the driven gear 38 can be integrally formed or fixed together. When the driving assembly 3 adopts a dual-axis motor 34, this structure has one more transmission stage than the first structure, which increases the transmission ratio and can reduce the rated torque of the driving motor under the same massage intensity.

[0057] Specifically, the two rotating shafts 21 are coaxial, that is, the axes of the two rotating shafts 21 are collinear. Under this arrangement, the side surfaces of the two second massage arms 27 (along the length direction of the second massage arms 27) are parallel, so that the two second massage arms 27 form a structure similar to the number 11, as shown in Figures 1 to 4, Figure 6, Figure 7 and Figure 10.

[0058] Alternatively, the axes of the two rotating shafts 21 are parallel, so that the side surfaces of the two second massage arms 27 (along the length direction of the second massage arms 27 ) are coplanar, and the two second massage arms 27 form a sub-type structure.

[0059] Specifically, to better conform to the figure-eight shape of the human neck and shoulders, the two massage assemblies 2 can be arranged in a figure-eight configuration. Unlike parallel placement of the two massage assemblies 2, in this case, the axes of the two rotating shafts 21 are arranged at an angle, with the angle between the axes of the two rotating shafts 21 being θ. Simultaneously, the mounting holes of the connecting seat 22, the position of the limit assembly 5, and the location of the elongated slot 11 are adjusted accordingly. Furthermore, since the rotation is driven by bevel gears, the precise transmission of the bevel gears is not affected when the rotating shaft 21 deflects about the axis of the active bevel gear 24.

[0060] The two massage components 2 can be arranged in an outward-to-outward-eight shape or an inward-to-eight shape. The outward-to-eight shape means that the ends of the two second massage arms equipped with the second massage heads are far away from each other, while the inward-to-eight shape means that the ends of the two second massage arms equipped with the second massage heads are close to each other.

[0061] As shown in Figure 9, when the two massage components are in an outward-facing "X" shape, the first massage arm 26 is used to massage the neck, and the second massage arm 27 is used to massage the shoulders. As shown in Figure 8, when the two massage components are in an "X" shape, the second massage arm 27 is used to massage the neck, and the first massage arm 26 is used to massage the shoulders. In this case, the second massage arm 27 can press the Fengchi acupoint behind the ear, achieving a refreshing effect.

[0062] Specifically, each of the first massage arms 26 has two first massage heads 28 , and the two first massage heads 28 are staggered with each other;

[0063] Each second massage arm 27 is integrally connected to a second massage head 29 , or the second massage head 29 has multiple second massage heads 29 , each second massage head 29 is matched with a different part of the human body, and each second massage head 29 is detachably connected to the second massage arm 27 .

[0064] Specifically, each of the limiting components 5 includes a fixing pin 51, which is connected to the housing 1 through a mounting base 52. Each of the second massage arms 27 is provided with an arcuate groove 271 that matches the fixing pin 51. The fixing pin 51 is slidably connected to the arcuate groove 271, and the fixing pin 51 passes through the arcuate groove 271 to constrain the movement trajectory of the second massage arm 27.

[0065] The specific applications of this massager are as follows:

[0066] The drive assembly 3 rotates the active bevel gear 24, driving the driven bevel gear 23, which in turn drives the rotating shaft 21. The eccentric wheel assembly 25, mounted on the outer wall of the rotating shaft 21, rotates under the drive of the rotating shaft 21. Because the second massage arm 27 is mounted on the outer wall of the cam 251 and constrained by the limit assembly 5, the second massage arm 27 reciprocates in the vertical direction. The first massage arm 26 is mounted on the angled eccentric wheel 252 and, constrained by the boss 261 and the elongated slot 11, reciprocates left and right, achieving a kneading effect.

[0067] In order to rationally utilize the space between the two massage components 2, this massager uses two rotating shafts 21 to drive the two massage components 2 respectively. A driven bevel gear 23 is set at one end of the rotating shaft 21, and the worm drives the horizontal worm wheel to rotate, which in turn drives the driving bevel gear 24 to rotate. Since the driving bevel gear 24 is meshed with the driven bevel gear 23, when the driving bevel gear 24 rotates, the rotating shaft 21 also rotates synchronously. Of course, another gear transmission can be added between the worm wheel and the driving bevel gear 24 to increase the reduction ratio and reduce the rated torque of the motor. A clearance area 4 is formed between the two driven bevel gears 23 of this massager, and the clearance area 4 is located above the drive component 3. The clearance area 4 is used to place batteries 6 or circuit boards 7.

[0068] As another embodiment of the present invention, to better fit the neck and shoulders of the human body, the massager can be installed with the two massage components 2 in an "inward-facing" or "outward-facing" configuration. When the two massage components are in an "outward-facing" configuration, the first massage arm 26 is used to massage the neck, and the second massage arm 27 is used to massage the shoulders. When the two massage components are in an "inward-facing" configuration, the second massage arm 27 is used to massage the neck, and the first massage arm 26 is used to massage the shoulders. In this case, the second massage arm 27 can press the Fengchi acupoint behind the ear, achieving a refreshing effect.

[0069] As another embodiment of the present invention, the eccentric wheel assembly 25 and rotating shaft 21 of one of the two massage assemblies 2 are modified, while the eccentric wheel assembly 25 and rotating shaft 21 of the other massage assembly 2 remain unchanged. A pin 211 is provided on one rotating shaft 21, the axis of which is perpendicular to the axis of the rotating shaft 21. A receiving groove 2511 for accommodating the pin 211 is provided on the side of the cam 251 near the driven bevel gear 23. A pusher 2512 is connected to the inner cavity of the receiving groove 2511. In the initial state, the pin 211 is in contact with the pusher 2512.

[0070] When the single-axis motor or the dual-axis motor rotates forward, the pin shaft 211 is in contact with the pushing part 2512 at this time, and the rotational torque of the rotating shaft 21 can be transmitted to the pushing part 2512 at the contact position between the pin shaft 211 and the pushing part 2512 to push the cam 251 to rotate, and the rotation of the cam 251 is a mirror image rotation of the cam 251 on the other side, realizing the mirror image movement of the left and right massage components 2, that is, the movement of the left and right first massage arms 26 and the second massage arms 27 are mirror images of each other, realizing the kneading function of the massager.

[0071] When the single-axis motor or the dual-axis motor rotates in reverse, the contacting pin 211 and the pusher 2512 separate. When the pin 211 rotates to the other side, the pin 211 re-contacts the pusher 2512 after the shaft 21 rotates 180 degrees. At this point, the rotational torque of the shaft 21 is transmitted to the pusher 2512, thereby driving the cam 251 to rotate. The pin 211, through the pusher 2512, drives the cam 251 on one side to rotate in a non-mirror-image manner with the cam 251 on the other side. That is, the rotation angles of the two eccentric wheel assemblies 25 differ by 180 degrees. At this point, the two massage assemblies 2 move synchronously, i.e., the two first massage arms 26 simultaneously swing to one side, and at any given moment, the two first massage arms 26 swing at the same angle, causing the head to swing left and right, thereby easing the meridians and activating the joints.

[0072] The present invention utilizes two sets of bevel gears to create a clearing 4 between the two massage components 2. This clearing 4 can be used to accommodate a battery 6 or circuit board 7, thereby eliminating or reducing the space typically required for battery 6 or circuit board 7. By effectively utilizing the space between the two massage components, the present invention reduces the size of the massager, making it more portable. Furthermore, by replacing different massage heads, the massager can be adapted to suit the massage pressure requirements of different individuals. Furthermore, by replacing the massage heads, the massager can also be used to massage other body parts, such as the legs and arms.
