DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1:

[0032] Reference Figure 1-Figure 8 A handheld massage mechanism 100 in a preferred embodiment of the utility model is used for users to hold and massage human body parts. For example, when it is necessary to massage the back, legs or waist of a human body, the handheld massage mechanism 100 can be directly placed on the corresponding human body part and fit with the human body part, so that the handheld massage mechanism 100 applies force to the human body part to achieve the purpose of massaging the part.

[0033] The handheld massage mechanism 100 includes a housing assembly 1 and a ball assembly 2, wherein the housing assembly 1 includes a main housing 11 and at least one handheld housing 12, the at least one handheld housing 12 is fixedly connected to the main housing 11, and the ball assembly 2 is rotatably arranged on the outside of the main housing 11. When a force is applied to the handheld housing 12 to drive the ball assembly 2 to rotate, the purpose of massage can be achieved. At this time, the force at this point should be a human force. That is, the user holds the handheld housing 12 to drive the ball assembly 2 to rotate.

[0034] However, in the above method, since the user applies force to massage, although the user gets a corresponding massage, the user also consumes corresponding physical strength. Therefore, in order to improve the massage feeling and the convenience of massage, the handheld massage mechanism 100 of the utility model further includes a rotating component 3 and a driving component 4. The structure of the handheld massage mechanism 100 of the utility model is specifically discussed below.

[0035] Specifically, the shell assembly 1 of the handheld massage mechanism 100 of the utility model includes a main shell 11 with a accommodating cavity and two handheld shells 12. The two handheld shells 12 are provided for the user to hold with both hands, or the user can take the handheld massage mechanism 100 from any side, providing more convenience.

[0036] The rotating assembly 3 includes a first rotating member 31, a second rotating member 32, and a plurality of connecting posts 33 fixedly connecting the first rotating member 31 and the second rotating member 32. The plurality of connecting posts 33 are equidistantly distributed along the circumference of the first rotating member 31 and the second rotating member 32. In this embodiment, the first rotating member 31 and the second rotating member 32 are provided with a plurality of equidistantly distributed mounting holes 34 along their circumferences, and the two ends of the connecting posts 33 are respectively inserted into the mounting holes 34 of the first rotating member 31 and the second rotating member 32, so that the first rotating member 31 and the second rotating member 32 are connected.

[0037] Furthermore, the first rotating member 31 and the second rotating member 32 are rotatably disposed on both sides of the main housing 11. One of the handheld housings 12 is connected to the main housing 11, and the other handheld housing 12 is connected to the main housing 11 through the first connecting member 8, so that the handheld massage mechanism 100 can be taken as a whole by taking the handheld housing 12.

[0038] In order to simplify the manufacturing process, the handheld housing 12 directly connected to the main housing 11 can be directly integrally injection molded with the main housing 11 during the injection molding process, and then demolded, which is more convenient and quick. In other embodiments, the handheld housing 12 can also be separated from the main housing 11 by injection molding and demolding, and then fixedly connected to the main housing 11 by bonding, fastener connection, etc.

[0039] In order to facilitate the user to take it, a groove 121 is further provided on the handheld shell 12. The groove 121 fits the shape of the fingers of the human hand, further improving the overall massage comfort of the handheld massage mechanism 100.

[0040] The handheld massage mechanism 100 further includes a connecting shaft rotatably connected to the second rotating member 32, part of the connecting shaft is disposed in the accommodating cavity, and the remaining part of the connecting shaft extends out of the accommodating cavity to be connected to the handheld housing 12. As can be seen from the foregoing, the other handheld housing 12 is fixedly connected to the main housing 11 through the first connecting member 8. In order to simplify the overall structure of the handheld massage mechanism 100, the first connecting member 8 serves as the connecting shaft. That is, one end of the first connecting member 8 is fixedly disposed in the main housing 11, and the other end of the first connecting member 8 is fixedly disposed in the handheld housing 12, while the second rotating member 32 is disposed between the main housing 11 and the handheld housing 12, and can rotate relative to the first connecting member 8.

[0041] The ball assembly 2 is rotatably disposed on the outer side of the main housing 11. The ball assembly 2 includes a plurality of ball members 21, each of which is sleeved on a connecting column 33. In this embodiment, the ball member 21 is sleeved on the connecting column 33 and can rotate relative to the connecting column 33. That is, the ball member 21 can rotate with the rotation of the first rotating member 31 and the second rotating member 32, and the ball member 21 itself can rotate relative to the connecting column 33, thereby further improving the comfort and flexibility of massage.

[0042] Each ball member 21 includes a body 211 and a plurality of protrusions 212 extending outward from the outer surface of the body 211. The plurality of protrusions 212 are evenly distributed on the body 211, and the protrusions 212 of two adjacent ball members 21 are staggered. The purpose of such arrangement is that during massage, the ball assembly 2 can perform a comprehensive massage on the massaged area, rather than being limited to a part, thereby improving the rolling feeling of the ball assembly 2 and further improving the comfort of the massage.

[0043] The driving assembly 4 is disposed in the accommodating cavity of the main housing 11, and includes a driving member 41 and a planetary gear box 42 connected to the driving member 41. In this embodiment, the driving member 41 is a brushless motor, which operates in an automatic control mode, so there is no additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, and there is no oscillation and loss of step when the load suddenly changes, so that the massage effect can be ensured while avoiding the increase of the overall weight of the handheld massage mechanism 100.

[0044] Among them, a heat dissipation hole 111 is also provided on the main shell 11 outside the driving member 41, so that the heat generated by the driving member 41 during operation is dissipated to the outside through the heat dissipation hole 111, thereby extending the service life of the driving member 41 and improving the massage feeling of the handheld massage mechanism 100.

[0045] The planetary gearbox 42 has a gear ring 423, which is mounted on the first rotating member 31. When the driving member 41 drives the planetary gearbox 42 to rotate, the first rotating member 31 rotates, and then drives the second rotating member 32 to drive the ball assembly 2 to rotate. It can be seen that by arranging the driving assembly 4 in the accommodating cavity, the driving assembly 4 can drive the rotating assembly 3 and the ball assembly 2 to rotate after starting, thereby realizing electric massage, saving labor and improving the comfort of massage, achieving multiple goals at one stroke.

[0046] In order to simplify the manufacturing process, in this embodiment, the gear ring 423 is integrally formed with the first rotating member 31. The first rotating member 31 has a hollow portion 311, and the gear ring 423 is formed on the inner surface of the hollow portion 311.

[0047] The planetary gearbox 42 further includes a first gear 421 fixedly connected to the driving shaft 411 of the driving member 41, at least two second gears 422 meshing with the first gear 421, and a planet carrier fixedly connected to the driving member 41, wherein the at least two second gears 422 are rotatably disposed on at least two supporting shafts of the planet carrier respectively; and the ring gear 423 meshes with the at least two second gears 422. In this embodiment, two second gears 422 are provided. In other embodiments, the number of the second gears 422 may also be other, such as three, four, etc., which is not specifically limited here and depends on the actual situation.

[0048] The central axis of the connecting shaft coincides or tends to coincide with the central axis of the driving shaft 411 of the driving member 41. The purpose of such arrangement is that when the driving member 41 drives the rotating assembly 3 to rotate, it can be more stable, and there is no need to add additional transmission components between the driving member 41 and the planetary gear box 42 for position layout, so that the overall structure of the handheld massage mechanism 100 is more compact and the overall volume of the handheld massage mechanism 100 is reduced.

[0049] The handheld massage mechanism 100 further includes a circuit assembly 5 and a button assembly 6 electrically connected to the circuit assembly 5, and the button assembly 6 is disposed on the handheld housing 12. In this embodiment, the button assembly 6 is disposed on one of the handheld housings 12, and correspondingly, the circuit assembly 5 is disposed in the handheld housing 12 close to the button assembly 6, so as to facilitate the wiring between the button assembly 6 and the circuit assembly 5.

[0050] Among them, the button assembly 6 includes at least two buttons, one of which is an on / off button, and the other is a mode adjustment button. When the on / off button is pressed, the driving assembly 4 starts to work; when the handheld massage mechanism 100 is in the on state as a whole, pressing the mode adjustment button can adjust the driving power of the driving member 41, and then adjust the massage mode of the handheld massage mechanism 100 as a whole. For example, the handheld massage mechanism 100 can be provided with three massage modes of low-grade, medium-grade and high-grade, and the pressing frequencies of low-grade, medium-grade and high-grade increase in sequence. When the mode adjustment button is pressed for the first time, the handheld massage mechanism 100 is in the low-grade massage mode as a whole; when the mode adjustment button is pressed again, the handheld massage mechanism 100 switches from the low-grade massage mode to the medium-grade massage mode; when the mode adjustment button is pressed again, the handheld massage mechanism 100 switches from the medium-grade massage mode to the high-grade massage mode. Then, when the user presses the mode adjustment button again, the handheld massage mechanism 100 switches from the high-grade massage mode to the low-grade massage mode, thereby performing reincarnation.

[0051] Alternatively, the massage mode can be switched according to the moving distance of the mode adjustment key. When the mode adjustment key is in the initial position, the handheld massage mechanism is in the low-grade massage mode as a whole; when the mode adjustment key is moved to the second position, the handheld massage mechanism 100 switches from the low-grade massage mode to the medium-grade massage mode; when the mode adjustment key is moved to the third position, the handheld massage mechanism 100 switches from the medium-grade massage mode to the high-grade massage mode. When it is necessary to switch the handheld massage mechanism 100 from the high-grade massage mode to the low-grade massage mode, the mode adjustment key is controlled to move to the initial position to switch the mode.

[0052] The circuit assembly 5 includes a circuit board, on which a plurality of components and a control chip are arranged. The structure of the circuit board is conventional, and the control program is also conventional, and the present application does not make corresponding improvements to the control program.

[0053] The handheld massage mechanism 100 also includes a power supply component 7, which is arranged in the accommodating cavity, and is located on both sides of the driving member 41 with the planetary gear box 42. In the present embodiment, the power supply component 7 is a lithium battery. In other embodiments, the power supply component 7 can also be a plurality of battery packs, which is not specifically limited here and depends on the actual situation. By arranging the power supply component 7 in the accommodating cavity, and the power supply component 7 and the driving component 4 respectively occupy half of the accommodating cavity, or the power supply component 7 and the driving component 4 tend to occupy half of the accommodating cavity, the weight distribution is performed, so that the center of gravity of the handheld massage mechanism 100 is located at its center, which is convenient for the placement, taking, and use of the handheld massage mechanism 100.

[0054] The utility model also provides a massage device, which includes the above-mentioned handheld massage mechanism 100 and a base 200 for placing the handheld massage mechanism 100. By providing the base 200, the handheld massage mechanism 100 can be directly placed on the base 200 and the driving component 4 drives the rotating component 3 and the ball component 2 to rotate. The user can directly fit the part to be massaged with the ball component 2 to massage, or take the handheld massage mechanism 100 and place it on the part to be massaged to massage, thereby providing various forms of massage, making the massage device more intelligent and multifunctional as a whole.

[0055] The base 200 includes two oppositely disposed placement pieces 201 and a second connecting piece 202 connecting the two placement pieces 201, and an escape groove is formed between the second connecting piece 202 and the two placement pieces 201. Each placement piece 201 has a placement groove 203, each placement groove 203 is for a handheld housing 12 to be placed, and the escape groove is for the remaining part of the handheld massage mechanism 100 to be accommodated. In this embodiment, in the height direction, the width of the orthographic projection of the placement piece 201 is greater than the width of the orthographic projection of the second connecting piece 202, so that when the user takes the handheld massage mechanism 100 placed on the base 200 from the side, the user's hand will not touch the edge of the second connecting piece 202, thereby not causing inconvenience in taking.

[0056] In summary, the handheld massage mechanism 100 is provided with a rotating assembly 3 and a driving assembly 4, the driving assembly 4 is arranged in the accommodating cavity of the main housing 11, and includes a driving member 41 and a planetary gear box 42, wherein the planetary gear box 42 has a gear ring 423, and the gear ring 423 is installed on the first rotating member 31 of the rotating assembly 3, so that when the driving member 41 drives the planetary gear box 42 to rotate, it can drive the first rotating member 31 to rotate to drive the rotating assembly 3 to rotate, and then drive the ball assembly 2 to rotate for massage, without applying artificial external force, which is more convenient and quick; at the same time, due to the provision of the planetary gear box 42, a relatively stable speed transmission can be achieved, thereby improving the overall massage comfort of the handheld massage mechanism 100;

[0057] Furthermore, by providing a base 200 on which the handheld massage mechanism 100 can be placed, the handheld massage mechanism 100 can be directly placed on the base 200 and the driving component 4 drives the rotating component 3 and the ball component 2 to rotate.
