Description

Technical Field

[0002] In daily life and work, people often experience discomfort in the muscles or bones of the body due to maintaining the same posture for a long time. In order to relieve the discomfort in the muscles or bones, various types of massagers have appeared on the market, such as waist massagers. In the related art, the waist massager is provided with a power mechanism and a massage head, wherein the massage head is rotatably connected to the eccentric wheel of the power mechanism, and the eccentric wheel is used to drive the massage head to perform eccentric movement, so that the massage head forms a massage action similar to the "kneading" of the palm, wherein when the palm is performing the "kneading" massage action, the movement trajectory of each position on the palm can be roughly regarded as a "circle" with the same shape and size and different center positions. However, since the massage head is rotatably connected to the eccentric wheel, the massage head will rotate in the process of being driven by the eccentric wheel, and the rotating massage head will twist the skin and cause discomfort.

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] Please refer to Figures 1 to 5 The present application provides a massage device 10, which can also be referred to as a massage movement. The massage device 10 is used to perform "kneading massage" on the massaged area. The massaged area can be, but is not limited to, the waist, legs, arms, neck, etc. The present application embodiment only takes the waist as an example. It should be noted that in order to facilitate the understanding of the accompanying drawings, Figure 5 The massage device 10 shown has some structural lines hidden. Figure 5 The filling process is only for the convenience of distinction and should not limit the present application.

[0054] The massage device 10 includes a housing 11, a power mechanism 12, and a first massage head 13. The power mechanism 12 is disposed in the housing 11, and includes a driver 121 and a first output member 122. The driver 121 is connected to the first output member 122 and can drive the first output member 122 to rotate. The first massage head 13 is disposed outside the housing 11, and the first output member 122 is rotatably connected to the first massage head 13. The driver 121 can drive the first massage head 13 to move through the first output member 122. Either the housing 11 or the first massage head 13 is provided with at least two constraint portions 113, and the other is provided with at least two matching portions 131. The constraint portion 113 has a ring-shaped constraint path X. The matching portion 131 is movably disposed on the constraint path X, and different matching portions 131 are matched and connected to different constraint portions 113 to prevent the first massage head 13 from generating self-rotation motion. When the first massage head 13 is driven by the first output member 122, the matching portion 131 performs a circular motion relative to the constraint portion 113 along the constraint path X, so that each position on the first massage head 13 presents a motion trajectory that is the same as the constraint path X, thereby causing the first massage head 13 to form a non-rotational circular motion.

[0055] Specifically, the shell 11 is a component used to carry, contain, protect, etc. It can be, but is not limited to, made of a single material such as metal, plastic, etc., and can also be a combination of multiple materials. Optionally, the shell 11 contains at least part of a plastic material. The use of plastic can facilitate manufacturing and molding, and can also reduce weight. The first output member 122 can be, but is not limited to, a gear. The first output member 122 is rotatably connected to the first massage head 13 so that the first output member 122 can rotate relative to the first massage head 13 to avoid the first output member 122 from getting stuck during the movement of the first massage head 13. The driver 121 can be, but is not limited to, a motor, an air pump, a hydraulic pump, etc. The motion output by the driver 121 can be a linear motion (such as a linear motor) or a rotational motion (such as a rotary motor). Since the motion required by the first output member 122 is rotation, for the driver 121 whose output motion is linear motion, this type of driver 121 can, but is not limited to, convert the linear motion into the rotational motion required by the first output member 122 through a gear-rack matching form; for the driver 121 whose output motion is rotational motion, this type of driver 121 can, but is not limited to, directly or intermittently transmit the rotational motion to the first output member 122 through a coupling or a gear-gear matching form or a worm-worm matching form.

[0056] Furthermore, in addition to being connected to the first output member 122, the first massage head 13 is also connected to the housing 11 through the constraint portion 113 and the matching portion 131. The constraint portion 113 can be provided on the housing 11 or on the first massage head 13; similarly, the matching portion 131 can be provided on the housing 11 or on the first massage head 13.

[0057] In one embodiment, see Figures 3 to 5 The shell 11 includes a shell body 117 and a constraint portion 113 connected to each other, wherein the constraint portion 113 is arranged on a side of the shell body 117 facing the first massage head 13; the first massage head 13 includes a massage head body 132 and a matching portion 131 connected to each other, wherein the matching portion 131 is arranged on a side of the massage head body 132 facing the constraint portion 113, and the matching portion 131 is movably connected to the constraint portion 113.

[0058] In another embodiment, the first massage head 13 includes a connected massage head body 132 and a constraint portion 113, wherein the constraint portion 113 is disposed on a side of the massage head body 132 facing the shell 11; the shell 11 includes a connected shell body 117 and a matching portion 131, wherein the matching portion 131 is disposed on a side of the shell body 117 facing the constraint portion 113, and the matching portion 131 is movably connected to the constraint portion 113.

[0059] It should be noted that, since the constraint principle of "the constraint portion 113 is provided on the first massage head 13 and the matching portion 131 is provided on the shell 11" is the same as the constraint principle of "the constraint portion 113 is provided on the shell 11 and the matching portion 131 is provided on the first massage head 13", the subsequent embodiments of the present application will only be described based on "the constraint portion 113 is provided on the shell 11 and the matching portion 131 is provided on the first massage head 13".

[0060] Further, the number of the constraint parts 113 and the matching parts 131 is at least two (i.e., greater than or equal to two), and specifically can be 2, 3, 4, etc. The number of the constraint parts 113 and the matching parts 131 is the same, and the constraint parts 113 and the matching parts 131 are matched and connected one by one, that is, one constraint part 113 is connected to one matching part 131, and different constraint parts 113 are connected to different matching parts 131. It can be understood that at least two constraint parts 113 and at least two matching parts 131 can form at least two pairs of matching relationships, so that the first massage head 13 can be prevented from rotating by the shell 11.

[0061] Furthermore, each constraint portion 113 is formed with a constraint path X, and the matching portion 131 is arranged on the constraint path X. It can be understood that when the first output member 122 drives the first massage head 13 to move relative to the housing 11, the matching portion 131 and the constraint portion 113 will also generate relative motion. Since the constraint portion 113 is formed with an annular constraint path X, the matching portion 131 performs a circular motion relative to the constraint portion 113 along the constraint path X. Under the cooperation of at least two pairs of constraint portions 113 and matching portions 131, each position on the first massage head 13 is defined as a circular motion trajectory, and the direction of the circular motion trajectory is the same as the direction of the constraint path X. In this way, the first massage head 13 presents a non-rotating circular motion, which is equivalent to the massage action of "kneading" by the palm.

[0062] Optional, see Figure 5 The first massage head 13 may further include a vibration motor 133, which is carried by the shell body 117. The number of the vibration motors 133 may be, but is not limited to, 1, 2, 3, etc. The vibration motor 133 is used to generate vibration during operation, so that the first massage head 13 can not only simulate the massage action of "kneading" by the palm, but also output a vibration effect, so that the user feels more comfortable.

[0063] Please refer to Figures 5 to 7, the first output member 122 includes an output body 1221 and an eccentric shaft 1222. The output body 1221 may be a gear structure, which is transmission-connected to the driver 121. The eccentric shaft 1222 extends out of the housing 11. One end of the eccentric shaft 1222 is fixedly connected to the output body 1221. The fixed connection here refers to the connection relationship between the eccentric shaft 1222 and the output body 1221 for synchronous movement. The fixed connection method may be a detachable connection or a non-detachable connection. Optionally, the eccentric shaft 1222 and the output body 1221 are an integrated structure. The other end of the eccentric shaft 1222 is also rotationally connected to the first massage head 13. The rotational connection relationship may be, but is not limited to, realized by a bearing 17, that is, the inner ring of the bearing 17 is sleeved on the outer periphery of the eccentric shaft 1222, and the first massage head 13 is sleeved on the outer periphery of the outer ring of the bearing.

[0064] Furthermore, the output body 1221 has a first axis Y1, and the eccentric shaft 1222 has a second axis Y2, and the first axis Y1 and the second axis Y2 are parallel to each other and spaced apart. The driver 121 is used to drive the output body 1221 to rotate with the first axis Y1 as the rotation center axis, so that the output body 1221 drives the eccentric shaft 1222 to eccentrically rotate with the first axis Y1 as the center axis. The constraint portion 113 and the matching portion 131 are used to prevent the first massage head 13 from rotating with the second axis Y2 as the rotation center axis, and are also used to make each position of the first massage head 13 present a motion trajectory that is the same as the constraint path X.

[0065] It can be understood that since the first axis Y1 and the second axis Y2 do not coincide, during the rotation of the first output member 122, the position of the eccentric shaft 1222 relative to the shell 11 will change periodically, and the eccentric shaft 1222 will drive the first massage head 13 to move, so the position of the first massage head 13 relative to the shell 11 will also change periodically, thereby prompting the constraint portion 113 and the matching portion 131 to produce relative movement, that is, the matching portion 131 performs periodic circular movement relative to the constraint portion 113 along the constraint path X, so that each position of the first massage head 13 can present a motion trajectory that is the same as the direction of the constraint path X, and can prevent the first massage head 13 from rotating with the second axis Y2 as the rotation center axis.

[0066] Furthermore, if the first massage head 13 can rotate, then its rotation center axis will coincide with the second axis Y2 of the eccentric shaft 1222, that is, the behavior of the first massage head 13 rotating around the second axis Y2 is self-rotation. In the present application, due to the cooperation of the constraint portion 113 and the matching portion 131, the first massage head 13 performs a non-self-rotation circular motion. Therefore, the rotation characteristics of the second axis Y2 rotating around the first axis Y1 can represent the characteristics of the motion trajectory of each position on the first massage head 13. For the second axis Y2, it rotates around the first axis Y1, so the motion trajectory of the second axis Y2 is a "circle", and the rotation radius of the second axis Y2 is "the distance from the first axis Y1 to the second axis Y2". Therefore, the shape of the motion trajectory of any point on the first massage head 13 is a circle, and the rotation radius of the motion trajectory is the distance from the first axis Y1 to the second axis Y2.

[0067] Please refer to Figure 5 The housing 11 has two restraining parts 113, and the first massage head 13 has two matching parts 131. The two restraining parts 113 are respectively connected to different matching parts 131, and the eccentric shaft 1222 is located between the two matching parts 131. It can be understood that the eccentric shaft 1222 is arranged between the two matching parts 131, which means that the two matching parts 131 are arranged along the radial direction of the first massage head 13, and the output power of the first output member 122 is located between the two matching parts 131, so that the movement of the first massage head 13 can be more stable without tilting, thereby ensuring that each position on the first massage head 13 can apply a relatively balanced massage force to the massaged part. Optionally, the two matching parts 131 are symmetrical based on the second axis Y2. Such a setting can further make the movement of the first massage head 13 more stable.

[0068] Please refer to Figure 3 and Figure 5 Optionally, the relative direction of the two restraining portions 113 is the extension direction of the housing 11. That is, the two restraining portions 113 are arranged along the extension direction of the housing 11, so that the space in the extension direction of the housing 11 can be fully utilized to set the restraining portions 113, avoiding the restraining portions 113 occupying the space in the width direction of the housing 11, which is conducive to reducing the width of the housing 11.

[0069] Please refer to Figures 5 to 9, the constraint portion 113 is formed with an annular groove Z5, and the annular groove Z5 constitutes the constraint path X. The matching portion 131 is a cylindrical structure and is slidably arranged in the annular groove Z5. In other words, the matching portion 131 is confined in the annular groove Z5 and is slidably matched with the constraint portion 113 through the annular groove Z5. When the first output member 122 drives the first massage head 13 to move, the matching portion 131 moves around along the direction of the annular groove Z5. The constraint portion 113 has a third axis Y3, and the third axis Y3 is the central axis of the annular groove Z5. The matching portion 131 has a fourth axis Y4, and the fourth axis Y4 is the central axis of the matching portion 131. The fourth axis Y4 is parallel to the third axis Y3. When the first output member 122 drives the first massage head 13 to move, the fourth axis Y4 of the matching portion 131 moves around the third axis Y3 of the constraint portion 113.

[0070] Furthermore, the distance between the first axis Y1 and the second axis Y2 is the first dimension H1. The distance between the third axis Y3 and the fourth axis Y4 is the second dimension H2. Among them, the value of H1 / H2 is 0.9 to 1.1, and the value can be but is not limited to 0.9, 0.95, 1.0, 1.05, 1.1. In this way, when the first massage head 13 rotates to different positions with the eccentric shaft 1222, the matching portion 131 of the first massage head 13 can synchronously and roughly abut against the constraint portion 113, thereby limiting the movement of the first massage head 13, ensuring that the trajectories of various positions on the first massage head 13 are basically consistent, so that the massage head will not rotate during the smooth circular movement, and will not twist when massaging the human body, simulating the massage action of palm kneading.

[0071] Please refer to Fig. 9 , the constraint portion 113 includes a first constraint sub-portion 1131 and a second constraint sub-portion 1132. The first constraint sub-portion 1131 and the second constraint sub-portion 1132 are both convexly arranged on the side of the shell body 117 facing the massage head body 132. Among them, the first constraint sub-portion 1131 is annular. The second constraint sub-portion 1132 can be annular or cylindrical. The first constraint sub-portion 1131 surrounds the outer circumference of the second constraint sub-portion 1132 and is spaced apart from the second constraint sub-portion 1132. An annular groove Z5 is defined between the first constraint sub-portion 1131 and the second constraint sub-portion 1132, and the annular groove Z5 constitutes a constraint path X. The matching portion 131 is a protruding structure convexly arranged on the first massage head 13, and the matching portion 131 can be slidably arranged in the annular groove Z5 and contacts the second constraint sub-portion 1132 and / or the first constraint sub-portion 1131.

[0072] Specifically, the first constraint sub-portion 1131 has a first side wall surface M5, and the second constraint sub-portion 1132 has a second side wall surface M6. The first side wall surface M5 and the second side wall surface M6 are arranged opposite to each other and spaced apart, thereby defining an annular groove Z5. When the matching portion 131 slides in the annular groove Z5, the matching portion 131 contacts the first side wall surface M5, or contacts the second side wall surface M6, or contacts the first side wall surface M5 and the second side wall surface M6 at the same time. In this way, the matching portion 131 can be constrained by the first side wall surface M5 and the second side wall surface M6, thereby preventing the first massage head 13 from rotating, and ensuring that the motion trajectory of each position on the first massage head 13 is circular. Furthermore, the first side wall surface M5 and the second side wall surface M6 are both arc-shaped cylinders, and the matching portion 131 is cylindrical, that is, the outer peripheral wall surface M7 of the matching portion 131 is an arc-shaped cylinder. Such a configuration allows the outer peripheral wall surface M7 of the matching portion 131 to slide more smoothly along the first side wall surface M5 and the second side wall surface M6, thereby ensuring that the first massage head 13 moves more smoothly.

[0073] Please refer to Figure 8 and Fig.10 The housing 11 includes a first housing 111, a second housing 112, and a connecting member 114. The first housing 111 and the second housing 112 are split structures. The so-called split structure means that the first housing 111 and the second housing 112 are formed independently. The first housing 111 and the second housing 112 are connected to each other to form a receiving chamber Z1, which is used to receive the power mechanism 12. The second constraint sub-portion 1132 is arranged on the side of the first housing 111 away from the second housing 112. The orthographic projection of the second constraint sub-portion 1132 on the first massage head 13 along the direction of the second housing 112 toward the first housing 111 falls within the range of the first massage head 13, that is, the first massage head 13 will block the second constraint sub-portion 1132. The second constraint sub-portion 1132 defines a receiving space Z6. The second constraint sub-portion 1132 is annular, and the space surrounded by it is the receiving space Z6.

[0074] Furthermore, the first shell 111 is provided with a first mounting hole Z2 connected to the accommodating space Z6. The second shell 112 is provided with a second mounting hole Z3 corresponding to the first mounting hole Z2. The accommodating space Z6 is used for the connection member 114 to pass through, so that the connection member 114 is inserted into the first mounting hole Z2 and the second mounting hole Z3 to fix the first shell 111 and the second shell 112 together. That is to say, during the assembly process, the connection member 114 can be inserted from the accommodating space Z6 into the first mounting hole Z2 and the second mounting hole Z3, so that the first shell 111 and the second shell 112 are fixedly connected through the connection member 114. Of course, the fixed connection mentioned here can be a detachable connection or a non-detachable connection. Among them, the first mounting hole Z2 and the second mounting hole Z3 can be threaded holes, and accordingly, the connection member 114 can be a threaded member with threads, such as screws, bolts, etc.

[0075] In this embodiment, the second constraint sub-portion 1132 is used to form a receiving cavity Z1, and the connecting member 114 can be blocked under the first massage head 13. If the connecting member 114 is a threaded member, the head of the threaded member can be received in the receiving cavity Z1. Such a configuration can not only hide the connecting member 114 to improve the aesthetics, but also use the second constraint sub-portion 1132 to avoid the connecting member 114 and the matching portion 131, so as to prevent the connecting member 114 from interfering with the normal movement of the first massage head 13.

[0076] Please refer to Fig.11 The massage device 10 further includes a second massage head 14, which can perform non-rotational motion under the drive of the driver 121. The first massage head 13 has a fifth axis Y5, and the second massage head 14 has a sixth axis Y6. The fifth axis Y5 and the sixth axis Y6 are arranged non-parallel to make the first massage head 13 and the second massage head 14 close to each other.

[0077] Specifically, the fifth axis Y5 of the first massage head 13 coincides with the second axis Y2 of the eccentric shaft 1222, and the matching portion 131 and the constraint portion 113 cooperate with each other to prevent the first massage head 13 from rotating with the fifth axis Y5 as the rotation center axis, and make the motion trajectory of each position on the first massage head 13 the same as the direction of the constraint path X, so that the first massage head 13 presents a non-rotational circular motion.

[0078] As for the second massage head 14, it is also used for non-rotational circular motion like the first massage head 13 to simulate the massage action of "kneading" the palm. The second massage head 14 and the housing 11 also realize non-rotational circular motion through the matching structure of the matching part and the constraint part. For details, please refer to the above drawings and corresponding descriptions of the first massage head 13. Here, only a brief description is given: either the housing 11 or the second massage head 14 is provided with at least two constraint parts, and the other is provided with at least two matching parts. The constraint part has a ring-shaped constraint path, the matching part is movably arranged on the constraint path, and different matching parts are matched and connected to different constraint parts to prevent the second massage head 14 from rotating, that is, to prevent the second massage head 14 from rotating around the sixth axis Y6. When the second massage head 14 is driven by the driver 121, the matching part performs a circular motion relative to the constraint part along the constraint path, so that each position on the second massage head 14 presents a motion trajectory that is the same as the constraint path, so that the second massage head 14 obtains non-rotational circular motion.

[0079] It is understandable that, from the left side to the right side (or the right side to the left side) of the human body, the human waist is curved and undulating. When the massage device 10 is worn on the waist, in order to ensure that the first massage head 13 and the second massage head 14 can "knead" the waist well, the massage device 10 should also be adapted to the curved and undulating trend of the waist. In this embodiment, the fifth axis Y5 and the sixth axis Y6 are arranged non-parallel, which means that the first massage head 13 and the second massage head 14 are relatively inclined, so that the first massage head 13 and the second massage head 14 are close to each other. In this way, when the massage device 10 is worn, the first massage head 13 and the second massage head 14 can adapt to the contour shape of the waist and stick to the left and right sides of the waist respectively, so as to ensure that the positions on both sides of the waist receive approximately the same massage force, and when the first massage head 13 and the second massage head 14 are close to each other, the waist position located between the first massage head 13 and the second massage head 14 can also form a pinching massage effect.

[0080] Please refer to Fig.12 The power mechanism 12 also includes a power introduction member 123 and a first input member 124. The power introduction member 123 is connected to the driver 121 and can rotate under the drive of the driver 121. The first input member 124 is respectively connected to the power introduction member 123 and the first output member 122. The power introduction member 123 can drive the first output member 122 to rotate about the first axis Y1 through the first input member 124. Among them, the first output member 122 and the first input member 124 can be but are not limited to be bevel gears, spur gears, helical gears, worm gears, etc. One or more transmission gears can also be set between the first output member 122 and the first input member 124, so that the first massage head 13 can output appropriate force or speed.

[0081] Optional, see Fig.13 , the power introduction member 123 is a worm and has a seventh axis Y7, which is the central axis of rotation of the worm, that is, when the driver 121 outputs power, the worm rotates around the seventh axis Y7. The first input member 124 is a worm wheel and has a first end face M1 and a second end face M2 that are opposite to each other. The seventh axis Y7 is located between the first end face M1 and the second end face M2. This arrangement can ensure that the worm wheel and the worm have more meshing area, so that the worm can output a larger and smoother power to the worm wheel, thereby ensuring that the first massage head 13 can move smoothly and output sufficient force. In addition, the worm-wheel matching form has the characteristics of a compact structure, which is conducive to reducing the volume and weight of the power mechanism 12, and the worm-wheel matching also has a self-locking function, which can prevent the waist from pressing against the first massage head 13 and causing the worm to reverse.

[0082] Please refer to Fig.13 There is a parallel plane M3 between the first end face M1 and the second end face M2, the parallel plane M3 is parallel to the first end face M1 and the second end face M2, and the distances from the parallel plane M3 to the first end face M1 and the second end face M2 are equal, and the center of the worm is located on the parallel plane M3. This arrangement can make the worm wheel and the worm gear mesh better, make the worm wheel force more uniform, and the life of the worm wheel can be longer.

[0083] Please refer to Fig.12 The power mechanism 12 further includes a second input member 126 and a second output member 127. The second input member 126 is respectively connected to the power introduction member 123 and the second output member 127. The power introduction member 123 can drive the second output member 127 to rotate through the second input member 126. The second output member 127 is rotatably connected to the second massage head 14, and the second output member 127 is used to drive the second massage head 14 to perform non-rotational circular motion during the rotation process. Among them, the second output member 127 and the second input member 126 can be, but are not limited to, bevel gears, spur gears, helical gears, worm gears, etc. One or more transmission gears can also be set between the second output member 127 and the second input member 126, so that the second massage head 14 can output appropriate force or speed.

[0084] Please refer to Fig.14, the first input member 124, the first output member 122 and the transmission gear between the first input member 124 and the first output member 122 are collectively referred to as the first transmission assembly. The second input member 126, the second output member 127 and the transmission gear between the second input member 126 and the second output member 127 are collectively referred to as the second transmission assembly. A symmetry plane M8 is provided between the first transmission assembly and the second transmission assembly, and the first transmission assembly and the second transmission assembly are symmetrical about the symmetry plane M8. It can be understood that symmetrically arranging the first transmission assembly and the second transmission assembly can ensure that the output effects of the first massage head 13 and the second massage head 14 are the same, so that the forces acting on the left and right sides of the waist by the first massage head 13 and the second massage head 14 are basically the same. Secondly, the weight of the first transmission assembly and the second transmission assembly can also be made equivalent, thereby avoiding the situation where the skewing occurs due to different weights during the massage process.

[0085] It can be understood that, since the first transmission assembly and the second transmission assembly are symmetrical about the symmetry plane M8, and the first input member 124 and the second input member 126 are connected to the same power introduction member 123, when the driver 121 is driven, the movement directions of the first massage head 13 and the second massage head 14 are opposite, so that the first massage head 13 and the second massage head 14 can be close to or away from each other, such as Figures 15 to 18 As shown, Figures 15 to 18 The figure shows the relative position relationship between the first massage head 13 and the second massage head 14 when the massage device 10 is in different working moments, and the dotted arrow circle in the figure represents the movement trajectory and direction of the second axis Y2 of the eccentric shaft 1222 rotating around the first axis Y1. When the first massage head 13 and the second massage head 14 are close to each other, the waist position between the first massage head 13 and the second massage head 14 can be pinched by the first massage head 13 and the second massage head 14, thereby forming a pinching massage effect. It should be noted that in order to facilitate the understanding of the drawings, Figures 15 to 18 The massage device 10 shown has some structural lines hidden. Figures 15 to 18 The padding in is only for easy distinction.

[0086] Please refer to Figures 19 to 21The housing 11 includes a first housing 111, a second housing 112, and a connector 114. The first housing 111 and the second housing 112 are connected to form a receiving chamber Z1, and the receiving chamber Z1 is used to receive the power mechanism 12. The first housing 111 includes a first sub-shell 1111 and a second sub-shell 1112, and the first sub-shell 1111 and the second sub-shell 1112 are split structures. The so-called split structure means that the first sub-shell 1111 and the second sub-shell 1112 are two independently formed components. The first sub-shell 1111 and the second sub-shell 1112 are both provided with at least one first mounting hole Z2, and the number of the first mounting holes Z2 on the first sub-shell 1111 and the second sub-shell 1112 can be 1, 2, 3, 4, 5, etc. It should be noted that the number of the first mounting holes Z2 on the first sub-shell 1111 and the number of the first mounting holes Z2 on the second sub-shell 1112 can be the same or different. The second housing 112 has second mounting holes Z3, the number of which is equal to the sum of the number of first mounting holes Z2 on the first sub-housing 1111 and the number of first mounting holes Z2 on the second sub-housing 1112, and the first mounting holes Z2 and the second mounting holes Z3 are arranged in a one-to-one correspondence. The connecting member 114 is inserted into the first mounting holes Z2 and the second mounting holes Z3 to connect the first housing 111 and the second housing 112 together.

[0087] In some embodiments, the first subshell 1111 and the second subshell 1112 may also be an integrated structure, where the integrated structure means that the first subshell 1111 and the second subshell 1112 are integrally formed. It is understandable that there may be errors in the manufacturing process of the first subshell 1111, the second subshell 1112, and the second shell 112. In the case of manufacturing errors, if the first mounting hole Z2 on the first subshell 1111 cannot be aligned with the second mounting hole Z3 on the second shell 112, then the first mounting hole Z2 on the second subshell 1112 is unlikely to be aligned with the second mounting hole Z3 on the second shell 112. Therefore, if the first subshell 1111 and the second subshell 1112 are an integrated structure, the two will affect each other, thereby affecting the accurate alignment process of the first mounting hole Z2 and the second mounting hole Z3.

[0088] In this embodiment, the first subshell 1111 and the second subshell 1112 adopt a split structure. During the assembly process, the first subshell 1111 and the second subshell 1112 can be assembled with the second shell 112 respectively, so that the first subshell 1111 and the second subshell 1112 can not affect each other, or the degree of mutual influence between the first subshell 1111 and the second subshell 1112 is reduced, so that the first mounting hole Z2 on the first subshell 1111 and the second subshell 1112 can be well aligned with the second mounting hole Z3 on the second shell 112. After the assembly is completed, there can be a gap between the first subshell 1111 and the second subshell 1112, and the gap is used to eliminate the manufacturing errors of the first subshell 1111 and the second subshell 1112.

[0089] In summary, the massage device 10 provided by the present application is provided with at least two constraint parts 113 and at least two matching parts 131. Different matching parts 131 are matched and connected to different constraint parts 113, so that at least two pairs of matching relationships can be formed, and then the first massage head 13 can be prevented from rotating by the shell 11. Further, when the first output member 122 drives the first massage head 13 to move relative to the shell 11, the matching part 131 and the constraint part 113 will also produce relative movement. Since the constraint part 113 forms a ring-shaped constraint path X, the matching part 131 will make a circular movement relative to the constraint part 113 along the constraint path X. Under the cooperation of at least two pairs of constraint parts 113 and matching parts 131, each position on the first massage head 13 is limited to a circular motion trajectory, and the direction of the circular motion trajectory is the same as the direction of the constraint path X. In this way, the first massage head 13 presents a non-rotating circular motion, and the non-rotating circular motion of the first massage head 13 is equivalent to the massage action of "kneading" by the palm.

[0090] Please refer to Fig. 22 The present application also provides a massage device 100, which can also be called a massager, a massage belt, etc. The massage device 100 includes a belt 20 and a massage device 10 of any of the above embodiments, and the massage device 10 is connected to the belt 20. For the specific situation of the massage device 10, please refer to the introduction of the previous embodiments.

[0091] The belt 20 is a component that is worn on the waist of the user when using the massage device 100. The belt 20 is made of a flexible material so that it can bend to adapt to the user's body curve. The flexible material of the belt 20 can be understood as a material that can be bent or deformed. For example, the material of the belt 20 can include at least one of cloth and soft rubber material.

[0092] The waist belt 20 has a belt length direction F3 and a belt width direction F4. The width direction of the massage device 10 is consistent with the belt width direction F4 of the waist belt 20. The massage device 10 can be set in the middle position of the waist belt 20 in the belt length direction F3, and can also be set at the end of the waist belt 20 in the belt length direction F3.

[0093] The massage device 100 has a non-use state, in which the belt 20 can be flattened and stretched to form a strip of a certain length, such as Fig. 22 The massage device 100 also has a state in which it can be worn on the waist. In this state, the belt 20 is wound into a substantially closed ring structure, which defines a wearing space Z4. The wearing space Z4 is used to accommodate the waist, that is, the user can wrap the belt 20 around his or her waist, as shown in FIG. Fig.23 shown.

[0094] Please refer to Fig.24 , the belt 20 may include a near-skin layer 21 and a far-skin layer 22 that are relatively arranged. The near-skin layer 21 refers to a material layer located on the side of the belt 20 facing the wearing space Z4, or in other words, the near-skin layer 21 is a material layer on the side of the belt 20 that is relatively close to the user when the user wears the massage device 100. The far-skin layer 22 refers to a material layer located on the side of the belt 20 that is away from the wearing space Z4, or in other words, the far-skin layer 22 is a material layer on the side of the belt 20 that is away from the user when the user wears the massage device 100. The housing 11 of the massage device 10 is disposed between the near-skin layer 21 and the far-skin layer 22, and the first massage head 13 and the second massage head 14 of the massage device 10 are disposed on the side of the near-skin layer 21 that is away from the far-skin layer 22.

[0095] Please refer to Fig.24 The housing 11 is divided into a first housing portion 115 and a second housing portion 116. Fig.24 The dotted line in represents the boundary line between the first shell 115 and the second shell 116. The first massage head 13 is carried by the first shell 115, and the second massage head 14 is carried by the second shell 116. The first shell 115 and the second shell 116 are bent and connected so that the angle between the first shell 115 and the second shell 116 is less than 180°, or in other words, the first shell 115 extends in the first direction F1, and the second shell 116 extends in the second direction F2, and the angle between the first direction F1 and the second direction F2 is less than 180°. The massage device 10 also includes a first abutment 15 and a second abutment 16. The first abutment 15 is provided on a side of the first shell 115 away from the first massage head 13. The second abutment 16 is provided on a side of the second shell 116 away from the second massage head 14. The first abutment 15 and the second abutment 16 are used to abut the far skin layer 22 of the waist belt 20.

[0096] It is understandable that the first shell 115 and the second shell 116 are bent and connected, so that the inclined setting of the first massage head 13 and the second massage head 14 can be adapted. However, when the first shell 115 and the second shell 116 are bent and connected, it is difficult for the far skin layer 22 of the belt 20 to abut against the side of the first shell 115 and the second shell 116 that are away from the first massage head 13 and the second massage head 14. Therefore, the first abutting member 15 and the second abutting member 16 are provided so that the far skin layer 22 of the belt 20 can strongly abut against the first abutting member 15 and the second abutting member 16, so that the massage head can be pressed against the waist by the belt 20, thereby ensuring that the first massage head 13 and the second massage head 14 have sufficient massage force on the waist.

[0097] Among them, the first supporting member 15 can be but not limited to plastic, rubber, metal, etc. The first supporting member 15 and the first shell portion 115 can be an integral structure or a split structure. Among them, the integral structure means that the first supporting member 15 and the first shell portion 115 are integrally formed, and the split structure means that the first supporting member 15 and the first shell portion 115 are independently formed. In the split structure, the connection between the first supporting member 15 and the first shell portion 115 can be a detachable connection or a non-detachable connection, wherein the detachable connection can be but not limited to connection through threaded parts (such as bolts), and the non-detachable connection can be but not limited to welding, bonding, etc. For the specific situation of the second supporting member 16, please refer to the introduction of the first supporting member 15, which will not be described here.

[0098] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
