[0062] As Figures 1 to 14As shown, according to an embodiment of the present utility model, a massager 100 is provided. The massager 100 includes a movement main body 10, a massage assembly 20, a transmission assembly 40, and a driving member 30. A first limiting member 12 is provided on the movement main body 10; the transmission assembly 40 includes a second driving shaft 427, and two second massage structures 22 are driven by the second driving shaft 427. The massage assembly 20 is provided on the movement main body 10, and the massage assembly 20 includes a first massage structure 21 and a second massage structure 22. The first massage structure 21 includes a first massage head 211 and a first driving shaft 212 that are connected to each other. The second massage structure 22 includes a second massage head 221 and a connecting arm 222 that are connected to each other. One end of the connecting arm 222 is in transmission connection with the second driving shaft 427. A first limiting structure 223 that cooperates with the first limiting member 12 is provided on the connecting arm 222. The first limiting structure 223 is used to limit the movement track of the second massage head 221; the driving member 30 is in transmission connection with the first driving shaft 212 and the second driving shaft 427, so that the first driving shaft 212 and the second driving shaft 427 rotate, so that the first massage head 211 and the second massage head 221 can move closer to or away from each other.

[0063] It should be noted that the movement main body 10 includes a housing 11. The housing 11 encloses a cavity for placing the driving member 30. Here, the housing 11 can be made of plastic or metal, and has the characteristics of being beautiful and drop-resistant. Here, the massager 100 can massage the user's shoulders and neck, and can also massage the user's waist and abdomen, and massage different parts through the cooperation of the first massage head 211 and the second massage head 221.

[0064] During the massage process, the distance between the first massage head 211 and the second massage head 221 changes, and the movement of the first massage head 211 is a rotational movement, and the movement of the second massage head 221 is a composite movement along the X-X direction and the Y-Y direction. Among them, the X-X direction is the left-right movement, and the Y-Y direction is the front-back direction. Figure 1 In, the distance between the first massage head 211 and the second massage head 221 is the largest. Figure 2 In, the distance between the first massage head 211 and the second massage head 221 is the smallest.

[0065] Among them, the movement track of the second massage head 221 is restricted by the first limiting structure 223. Specifically, one of the first limiting member 12 and the first limiting structure 223 is a pin member, and the other of the first limiting member 12 and the first limiting structure 223 is a groove-like structure, and the groove-like structure is a long strip groove. During the operation of the driving member 30, the cooperation of the first limiting member 12 and the first limiting structure 223 is used to realize the composite movement of the second massage head 221 along the X-X direction and the Y-Y direction.

[0066] The first limiting member 12 here can be a pin member, and the first limiting structure 223 is a groove structure; or, the first limiting member 12 is a groove structure, and the first limiting structure 223 is a pin member, and the movement stroke of the second massage head 221 is constrained by the cooperation of the pin member and the groove structure.

[0067] In addition, if Figure 4 and Figure 8 As shown, the first driving shaft 212 here adopts an eccentrically arranged structure, so that the first massage head 211 can generate an eccentric rotational motion.

[0068] It should be noted that if Figure 9 and Figure 12 As shown, when the first stopper 12 is connected to the housing 11, that is, the first stopper 12 is connected to the housing 11, a first stopper structure 223 is formed on the connecting arm 222, and at this time, the first stopper 12 and the housing 11 can be an integrated structure or a separate structure. Of course, as an alternative, the first stopper 12 can also be interchanged with the first stopper structure 223, that is, the first stopper structure 223 is formed on the housing 11, and the first stopper 12 is formed on the connecting arm 222.

[0069] According to the massager 100 of the utility model, when working, the driving member 30 can drive the first massage head 211 and the second massage head 221 to move closer to or away from each other, so that the distance between the first massage head 211 and the second massage head 221 can be adjusted to achieve kneading of the shoulder and neck, thereby increasing the kneading stroke and thus improving the kneading effect and improving the comfort of the massage process.

[0070] The following will be combined Figures 3 to 9 The structure shown in FIG. 1 is used to introduce the driving structure of the massager 100 .

[0071] Optionally, the driving member 30 is respectively connected to the first driving shaft 212 and the second driving shaft 427 in a transmission manner, which means that the driving member 30 can drive the first driving shaft 212 and the second driving shaft 427 to rotate. It should be noted that the transmission assembly 40 is also located inside the housing 11.

[0072] The driving member 30 here may be a motor component, wherein the motor component is provided with an output gear 31 , and the transmission assembly 40 here can transmit the power of the driving member 30 to the first massage head 211 and the second massage head 221 .

[0073] Alternatively, if Figure 3 and Figure 4As shown, the transmission assembly 40 includes a first transmission structure 41 and a second transmission structure 42. The first transmission structure 41 is in transmission connection with the driving member 30, and the driving member 30 drives the first driving shaft 212 to rotate through the first transmission structure 41. Specifically, the first transmission structure 41 includes a gear set, and the gear set is connected to the output gear 31 of the driving member 30; the gear set includes a first gear 411, and the first gear 411 is in transmission connection with the first driving shaft 212.

[0074] As Figure 5 shown, the first driving shaft 212 here is eccentrically arranged on the first gear 411, and the first massage head 211 can rotate around the first driving shaft 212, expanding the movement range of the first massage head 211. Alternatively, the first driving shaft 212 can also be arranged at the central position of the first gear 411, so that the first massage head 211 makes a circular motion, which can also change the distance between the first massage head 211 and the second massage head 221, realizing the kneading massage effect.

[0075] It should be noted that the output gear 31 here can be a helical gear. Correspondingly, the third gear 413 is also a helical gear and can mesh with the output gear 31.

[0076] The gear set here can only adopt one first gear 411. Among them, the first gear 411 is directly or indirectly meshed with the output gear 31 of the driving member 30, and the rotation of the first gear 411 can drive the first driving shaft 212 to rotate, thereby driving the first massage head 211 to rotate.

[0077] Optionally, the first massage structure 21 further includes a first bracket 213. Among them, the first bracket 213 is connected to the first driving shaft 212, and the first bracket 213 is connected to the first massage head 211 to realize the transmission of power.

[0078] Optionally, as Figure 3 shown, the gear set further includes a second gear 412 and a third gear 413. Among them, the third gear 413 is in transmission connection with the output gear 31 of the driving member 30; the second gear 412 includes a first sub-gear 4121 and a second sub-gear 4122 arranged coaxially. Among them, one of the first sub-gear 4121 and the second sub-gear 4122 is meshed with the third gear 413, and the other of the first sub-gear 4121 and the second sub-gear 4122 is meshed with the first gear 411, so that the power can be transmitted through the gear set composed of three gears, driving the first driving shaft 212 to rotate.

[0079] Of course, the gear set may also only include the first gear 411 and the second gear 412, and the power transmission can also be achieved, driving the rotation of the first drive shaft 212 on the first gear 411.

[0080] Optionally, as Figure 3 and Figure 4 shown, the massager 100 further includes an eccentric wheel assembly, and the second transmission structure 42 is in transmission connection with the first gear 411; the second transmission structure 42 includes a second drive shaft 427 and a transmission component. The first gear 411 drives the second drive shaft 427 to rotate. One end of the connecting arm 222 is sleeved outside the eccentric wheel assembly, and the second drive shaft 427 drives the connecting arm 222 to move through the eccentric wheel assembly. Here, the second transmission structure 42 can be in transmission connection with the first transmission structure 41, so that the first drive shaft 212 and the second drive shaft 427 can be driven simultaneously by a driving member 30, thereby realizing the simultaneous movement of the first massage head 211 and the second massage head 221.

[0081] Optionally, the transmission component of the second transmission structure 42 includes one of a gear transmission structure, a chain transmission structure, and a belt transmission structure. That is to say, the transmission component of the second transmission structure 42 can be a gear transmission structure, a belt transmission structure, or a chain transmission structure. Among them, in Figure 3 , the second transmission structure 42 adopts a gear transmission structure, and in Figure 4 , the second transmission structure 42 adopts a belt transmission structure.

[0082] Among them, the chain transmission structure can use a common chain for transmission, and no further description will be given here. The specific structures of the gear transmission structure and the belt transmission structure will be described in detail below.

[0083] Optionally, as Figure 3 shown, the first gear 411 includes a third sub-gear 4111 and a fourth sub-gear (not shown) arranged coaxially. Among them, the fourth sub-gear is located on one side of the third sub-gear 4111 along the axial direction, and the third sub-gear 4111 is meshed and connected with the second gear 412; the gear transmission structure includes a fourth gear 421, and the fourth gear 421 is in transmission connection with the fourth sub-gear, and a second drive shaft 427 is provided on the fourth gear 421.

[0084] The gear transmission structure here only uses one gear to achieve power transmission, or a gear set can also be used to achieve power transmission. For example, the gear transmission structure further includes a fifth gear 422 and a sixth gear 423. Among them, the fourth gear 421 is meshed and connected with the fifth gear 422, and the fifth gear 422 is meshed and connected with the sixth gear 423. Among them, the fifth gear 422 has a coaxial double-gear structure, and the two gears are respectively meshed and connected with the sixth gear 423 and the fourth gear 421. Among them, the sixth gear 423 is meshed and connected with the fourth sub-gear.

[0085] Optionally, as Figure 4 , Figure 5 and Figure 6 shown, the belt transmission structure includes a first pulley 424, a second pulley 425 and a transmission belt 426. The first pulley 424 is coaxially arranged with the first gear 411; a second drive shaft 427 is provided on the second pulley 425; the transmission belt 426 is respectively in transmission connection with the first pulley 424 and the second pulley 425.

[0086] Whether the second transmission structure 42 is a gear transmission structure or a belt transmission structure, it can achieve power transmission.

[0087] Optionally, as Figure 1 and Figure 2 shown, the number of the first massage structure 21 and the second massage structure 22 is two or more. Among them, the first massage head 211 of the first massage structure 21 and the corresponding second massage head 221 can massage the shoulders and neck. In Figure 1 , the number of the first massage structure 21 and the second massage structure 22 is two. That is to say, the number of the first massage heads 211 is two, and the number of the second massage heads 221 is also two. Among them, the first massage head 211 and the second massage head 221 on the left cooperate with each other, and the first massage head 211 and the second massage head 221 on the right cooperate with each other to respectively achieve the effect of kneading massage.

[0088] Optionally, as Figure 14 shown, the eccentric wheel assembly includes at least one eccentric wheel. Among them, the second drive shaft 427 passes through the eccentric wheel and can drive the eccentric wheel to rotate. The number of the eccentric wheels here can be one, two or more. Here, the number of the eccentric wheels is two for expansion and explanation.

[0089] As Figure 6As shown, the two eccentric wheels are the first eccentric wheel 50 and the second eccentric wheel 60 respectively. A first through hole 51 is provided on the first eccentric wheel 50. The second eccentric wheel 60 and the first eccentric wheel 50 are arranged at an angle. That is to say, the center lines of the second eccentric wheel 60 and the first eccentric wheel 50 are in a parallel and spaced state. Among them, a second through hole 61 is provided on the second eccentric wheel 60. The second drive shaft 427 passes through the first through hole 51 and the second through hole 61 and is connected to the first eccentric wheel 50 and the second eccentric wheel 60. The first eccentric wheel 50 and the second eccentric wheel 60 rotate driven by the second drive shaft 427. The two connecting arms 222 are respectively sleeved on the outer peripheral surfaces of the first eccentric wheel 50 and the second eccentric wheel 60, and the two connecting arms 222 are respectively connected to the two second massage heads 221. That is to say, the number of the connecting arms 222 is two. Among them, one end of one connecting arm 222 is sleeved on the outer peripheral surface of the first eccentric wheel 50, and the other end is connected to one second massage head 221. One end of the other connecting arm 222 is sleeved on the outer peripheral surface of the second eccentric wheel 60, and the other end is connected to the other second massage head 221.

[0090] Among them, Figure 14 As shown, both the first through hole 51 and the second through hole 61 are in the structure of an arcuate hole. The relative position between the first eccentric wheel 50 and the second eccentric wheel 60 can be determined by using the planar walls of the first through hole 51 and the second through hole 61. Correspondingly, arcuate notches are provided on both sides of the first drive shaft 212 here to facilitate inserting the first drive shaft 212 into the first through hole 51 and the second through hole 61 respectively.

[0091] It should be noted that as Figure 9 shown, the angle between the first eccentric wheel 50 and the second eccentric wheel 60 is α. The angle of α can be from 30 degrees to 180 degrees, such as 90 degrees, 100 degrees, 120 degrees or 150 degrees. And the rotation directions of the first eccentric wheel 50 and the second eccentric wheel 60 are the same, both rotating in the clockwise direction or the counterclockwise direction.

[0092] The angle α here can be obtained by measuring the angle between the planar walls of the first through hole 51 and the second through hole 61. By using this method, the angle α between the first eccentric wheel 50 and the second eccentric wheel 60 can be determined.

[0093] It should be noted that the moments when the two second massage heads 221 move to the uppermost end in the Y-Y direction do not need to be the same. That is to say, the movements of the two second massage heads 221 are independent of each other and do not need to move symmetrically.

[0094] In the massager 100 of the present utility model, the first massage head 211 generates an eccentric circular motion, and the second massage head 221 generates a compound motion along the X-X direction and the Y-Y direction. Through the change in the distance between the first massage head 211 and the second massage head 221, a kneading action can be achieved, thus realizing the massage effect.

[0095] For the structures of other parts of this application, please refer to the prior art, and no further elaboration will be provided here.

[0096] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
