The second massage structure 42 includes a second massage head 421 and a connecting arm 422 that are connected to each other. A first limiting structure 4221 that cooperates with the first limiting member is provided on the connecting arm 422. The first limiting structure 4221 is used to define the movement track of the second massage head 421; the first driving member 50 is in transmission connection with the first driving shaft 412 and the connecting arm 422, so that the first massage head 411 and the second massage head 421 can move closer to or away from each other.

[0077] The massager 100 here can be a shoulder and neck massage device for massaging the user's shoulder and neck, or a waist and abdomen massage device for massaging the user's waist and abdomen.

[0078] It should be noted that the first limiting member here can be connected to the surface of the housing 11 or extend out of the movement main body 10 through the housing 11. In addition, the adjusting assembly 30 here can be entirely disposed inside the housing 11, or partially located inside the housing 11 and partially located outside the housing 11, or entirely located outside the housing 11, which will be specifically described according to the embodiments later. When a part of the first limiting member is located inside the housing 11, an adjusting hole 111 can be provided on the housing 11 so that the first limiting member moves within the range defined by the adjusting hole 111.

[0079] According to the massager 100 of the present utility model, by providing a first limiting member outside the movement main body 10 and providing an adjusting assembly 30 connected to the first limiting member, the position of the first limiting member relative to the first limiting structure 4221 can be adjusted through the adjusting assembly 30, thereby changing the movement track of the second massage head 421, adjusting the minimum distance between the first massage head 411 and the second massage head 421 during the massage process, and adjusting the massage force of the first massage head 411 and the second massage head 421.

[0080] It should be noted that the upper part of the first position-limiting member here can be a columnar structure, such as a cylindrical structure, a rectangular column structure or a polygonal column structure, and correspondingly, the first position-limiting structure 4221 here is a groove structure or a hole structure, such as a long strip hole or a long strip groove structure. Of course, the first position-limiting member and the first position-limiting structure 4221 here can also be interchangeable, that is, the first position-limiting structure 4221 is a columnar structure, and the first position-limiting member is a groove structure or a hole structure.

[0081] In order to achieve the installation of the first limit member, optionally, the first limit member also includes a mounting portion 60 and a limit portion 20. The limit portion 20 is the upper half of the first limit member and can be a columnar structure, such as a cylindrical structure, a rectangular column structure or a polygonal column. The mounting portion 60 is connected to the adjustment component 30, and the mounting portion 60 is provided with the limit portion 20. The adjustment component 30 adjusts the position of the limit portion 20 by moving the mounting portion 60. That is to say, the adjustment component 30 can drive the mounting portion 60 to move, thereby moving the position of the limit portion 20 to achieve the position adjustment of the limit portion 20, wherein the limit portion 20 is located above the mounting portion 60, and the limit portion 20 and the mounting portion 60 can be an integrated structure, so that the mounting portion 60 can drive the limit portion 20 to move accordingly when moving.

[0082] The mounting portion 60 here can be a rectangular block structure or a cylindrical block structure. It can be an integral structure with the limiting portion 20 or a separate structure from the limiting portion 20. The limiting portion 20 can be formed on the mounting portion 60 to achieve the installation of the limiting portion 20.

[0083] The following will be combined Figures 3 to 25 The structure of the adjustment component 30 is described in detail. The adjustment component 30 can adopt various structures to adjust the position of the mounting portion 60, such as Figures 3 to 16 As shown, the first structure of the adjustment component 30 will be described in detail below.

[0084] Specifically, the adjustment assembly 30 includes a bidirectional adjustment structure, which is transmission-connected to the mounting portion 60. The bidirectional adjustment structure here refers to the ability to adjust the position of the limit portion 20 in two directions, and is used to adjust the reciprocating motion of the limit portion 20 along a first direction, wherein the first direction is Figure 1 In other words, the limiting portion 20 can move to the left or to the right along the XX direction.

[0085] Optionally, the bidirectional adjustment structure includes a bidirectional locking structure 31. The bidirectional locking structure 31 includes a ratchet member 311 and a ratchet seat 312 that are engaged with each other.

The first ratchet tooth ring 3121 and the second ratchet tooth ring 3122 are arranged in sequence along the axial direction of the ratchet seat 312.

[0088] It should be noted that the ratchet member 311 further includes a body portion 3113 and a ratchet arm 3114. Among them, the body portion 3113 and the first ratchet buckle 3111 are connected by the ratchet arm 3114, and the body portion 3113 and the second ratchet buckle 3112 are connected by another ratchet arm 3114. There is a hollow gap 3115 between the first ratchet buckle 3111 and the body portion 3113, and there is also a hollow gap 3115 between the second ratchet buckle 3112 and the body portion 3113, and the gap 3115 is curved. With this design of the gap 3115, the first ratchet buckle 3111 and the second ratchet buckle 3112 have better elasticity and are easier to separate from the ratchet seat 312 during rotation.

[0089] The first ratchet buckle 3111 and the second ratchet buckle 3112 are arranged in layers along the axial direction of the body portion 3113. Among them, the inner side surface of the first ratchet buckle 3111 along the circumferential direction of the ratchet member 311 is a right-angle surface, and the outer side surface is an arc surface. The inner side surface of the second ratchet buckle 3112 along the circumferential direction of the ratchet member 311 is a right-angle surface, and the outer side surface is an arc surface. The ratchet seat 312 is sleeved on the outside of the ratchet member 311. At this time, the right-angle surface of the first ratchet buckle 3111 is stuck at the tooth surface of the first ratchet tooth of the first ratchet tooth ring 3121, and the right-angle surface of the first ratchet buckle 3111 is stuck at the tooth surface of the second ratchet tooth of the second ratchet tooth ring 3122.

[0090] Optionally, a first through hole 3118 is provided on the body portion 3113, so that the rotating shaft 315 can pass through the first through hole 3118 and then be connected to the connecting member 314.

[0091] The ratchet seat 312 here is a hollow sleeve-like structure. The first ratchet tooth ring 3121 is arranged on the outer side of the inner hole of the sleeve-like structure, and the second ratchet tooth ring 3122 is arranged on the inner side of the first ratchet tooth ring 3121.

[0092] Optionally, the bidirectional adjustment structure further includes a knob 313, a connecting member 314, a rotating shaft 315, a fixed seat 316, a first gear 317, and a transmission bar 318. The knob 313 is connected to the connecting member 314; the ratchet member 311 is connected to the rotating shaft 315 and can drive the rotating shaft 315 to rotate. The ratchet seat 312 is fixedly sleeved on the outer peripheral surface of the rotating shaft 315; the ratchet seat 312 is arranged in the fixed seat 316; the first gear 317 is sleeved on the outer peripheral surface of the rotating shaft 315; the transmission bar 318 is meshed and connected to the first gear 317, and the transmission bar 318 is connected to the mounting portion 60.

[0093] Here, the transmission bar 318 can be one, which realizes the movement of one mounting portion 60. Usually, there are two transmission bars 318, which can move the two transmission bars 318 simultaneously through the first gear 317, so as to move the mounting portion 60.

[0094] It should be noted that the knob 313 and the connecting member 314 can be connected by a buckle, so that the connecting member 314 can rotate correspondingly with the rotation of the knob 313.

[0095] In addition, there is an overlapping part between the two transmission bars 318. Each transmission bar 318 is provided with a through hole through which the rotating shaft 315 can pass, and the through hole is a rectangular through hole. A strip of teeth 3181 is arranged on an inner wall surface of the rectangular through hole. The strip of teeth 3181 of the two transmission bars 318 are arranged oppositely and can be meshed and driven with the first gear 317 at the same time, so that the rotation of the first gear 317 can drive the two transmission bars 318 to move at the same time, realizing the approach or separation between the two transmission bars 318.

[0096] Optionally, the first massage structure further includes a robotic arm 413. The robotic arm 413 can connect the first massage head 411 and the first drive shaft 412 to realize the rotation of the first massage head 411.

By rotating the first gear 317, the two transmission bars 318 approach or separate from each other, so as to simultaneously adjust the positions of the two limiting portions 20.

[0098] Optionally, as Figure 14 shown, one of the connecting member 314 and the ratchet member 311 is provided with a first receiving hole 3142, and the other of the connecting member 314 and the ratchet member 311 is provided with a first pin member 3116. The first pin member 3116 and the first receiving hole 3142 are inserted and matched with each other. The first receiving hole 3142 has a first annular structure, and the first annular structure is arranged around the axis of the rotating shaft 315.

[0099] Specifically, the first receiving hole 3142 can be provided on the connecting member 314, and the first pin member 3116 can be provided on the ratchet member 311, and the first pin member 3116 can be inserted and matched with the first receiving hole 3142, so that the ratchet member 311 can be driven to rotate by the connecting member 314. Of course, the opposite structure can also be adopted, such as providing the first pin member 3116 on the connecting member 314 and providing the first receiving hole 3142 on the ratchet member 311, and driving the ratchet member 311 to rotate by the cooperation of the first pin member 3116 and the first receiving hole 3142 through the connecting member 314.

Among them, the first part 31171 is arranged around the axis of the rotating shaft 315, and the inner diameter of the second part 31172 is larger than the inner diameter of the first part 31171.

[0102] In Figure 15 it, the center of the first part 31171 coincides with the center of the rotating shaft 315, and the center of the second part 31172 is located at the lower left side of the center of the rotating shaft 315.

[0103] The number of the second receiving holes 3117 can also be two, and the second receiving holes 3117 are respectively formed on two ratchet arms 3114. The two second pin members 3141 can be respectively inserted into the second receiving holes 3117 to rotate, so as to drive the ratchet member 311 to rotate by the connecting member 314.

[0104] It should be noted that the knob 313 is located outside the housing 11, and the user can adjust the position of the limiting part 20 by rotating the knob 313 clockwise or counterclockwise.

[0105] Optionally, a second through hole 3143 is provided at the central position of the connecting member 314, so that the rotating shaft 315 can pass through the second through hole 3143. The second through hole 3143 may be a circular through hole.

[0106] The working process of the bidirectional locking structure 31 will be described below.

[0107] As Figure 15 shown, when the massager 100 is in the normal state and the knob 313 is not rotated, the two second pin members 3141 on the connecting member 314 are respectively inserted into the central positions of the second receiving holes 3117 of the ratchet member 311. At this time, the first ratchet 3111 and the second ratchet 3112 of the ratchet member 311 are respectively in a state of engaging with the first ratchet tooth ring 3121 and the second ratchet tooth ring 3122 of the ratchet seat 312. The first gear 31723 cannot rotate, and the two transmission bars 318 cannot be engaged with the first gear 317 for transmission and have displacement, so there will be no relative movement between the two transmission bars 318. In this state, the minimum distance between the first massage head 411 and the second massage head 421 is L2, and the massager 100 is turned on to produce a moderately strong massage effect.

[0108] When the user needs to increase the massage intensity, rotate the knob 313 clockwise (from the perspective of looking down from above in Figure 9 ), and the connecting member 314 will also rotate clockwise. The first ratchet 3111 and the first ratchet tooth ring 3121 are in arc surface contact. Therefore, the first ratchet 3111 can move clockwise relative to the first ratchet tooth ring 3121. At the same time, the second pin member 3141 located below drives the lower ratchet arm 3114 of the ratchet member 311 to deform, and the end of the ratchet arm 3114 approaches the center of the ratchet member 311. Thus, the ratchet arm 3114 will be disengaged from the restraint of the ratchet seat 312, so that the knob 313 can drive the rotating shaft 315 to rotate. When the first gear 317 on the rotating shaft 315 rotates, it can control the transmission bars 318 to move closer to each other (in the direction in Figure 9 ), so as to realize the position adjustment of the limiting part 20, so that the position of the limiting part 20 becomes the state shown in Figure 28 . At this time, the distance between the first massage head 411 and the second massage head 421 is L3, and L3 is less than L2. When the user uses the massager 100, a stronger massage effect can be produced.

[0109] When the user needs to reduce the massage intensity, rotate the knob 313 counterclockwise (from the perspective of looking down from above in Figure 9In the perspective of looking down from above, the connecting member 314 will also rotate counterclockwise, and the ratchet member 311 will rotate out of the restraint of the ratchet seat 312, so as to drive the rotating shaft 315 to rotate. When the first gear 317 on the rotating shaft 315 rotates, it can control the transmission bar 318 to move away from each other, so as to realize the position adjustment of the limiting part 20, so that the position of the limiting part 20 becomes Figure 26 The state shown in the figure. At this time, the distance between the first massage head 411 and the second massage head 421 is L1, and L1 is greater than L2. When the user uses the massager 100, a massage effect with a smaller force can be generated.

[0110] Above, we mentioned the structure adjusted by the bidirectional locking structure 31. Here, the adjusting assembly 30 can also be replaced by other structures.

[0111] Optionally, as Figures 17 to 25 shown, the adjusting assembly 30 includes a driving and adjusting structure 32. The driving and adjusting structure 32 includes a second driving member 321 and an adjusting transmission assembly 322. The second driving member 321 is connected to the adjusting transmission assembly 322, and the adjusting transmission assembly 322 is connected to the mounting portion 60.

[0112] Optionally, the second driving member 321 includes one of a manual knob 313 and a motor. Among them, the manual knob 313 is driven by manual operation, and the motor is driven by an automatic control structure. In Figure 19 and Figure 20 In, the second driving member 321 is operated by the structure of the manual knob 313. In Figures 21 to 25 In, the second driving member 321 is driven by the structure of the motor. Among them, the motor can be placed horizontally or vertically, and the driving effect can be achieved.

[0113] Optionally, the adjusting transmission assembly 322 includes a connecting shaft 3221, a gear set 3222 and a threaded rod 3223. One of the manual knob 313 and the motor is in transmission connection with the connecting shaft 3221; the gear set 3222 is in transmission connection with the connecting shaft 3221; the threaded rod 3223 is in transmission connection with the gear set 3222, and the threaded rod 3223 is in transmission connection with the mounting portion 60.

[0114] Optionally, as Figure 22 shown, the gear set 3222 includes a plurality of spur gears connected in mesh. In Figure 22 In, the number of spur gears of the adjusting transmission assembly 322 is four. Among them, two spur gears are connected to the connecting shaft 3221 of the motor, and the other two spur gears are respectively meshed with these two spur gears.

[0115] Alternatively, as Figure 20As shown, the gear set 3222 includes a plurality of meshed helical gears. Among them, the number of helical gears is three. One helical gear is connected to the connecting shaft 3221, and the other two helical gears are respectively meshed with this helical gear. By the movement of the threaded rod 3223, the position of the mounting portion 60 is adjusted, so as to adjust the position of the limiting portion 20 on the mounting portion 60.

[0116] Optionally, in order to achieve the massage effect of the massager 100, the first driving member 50 here includes a first driving motor 51 and an output gear 52. Among them, the second gear 53 is meshed with the output gear 52, and the second gear 53 is meshed with the third gear 54. Among them, the third gear 54 is a coaxial double gear. One gear of the third gear 54 is meshed with the second gear 53, and the other gear of the third gear 54 is meshed with the fourth gear 55. Among them, the first driving shaft 412 is arranged on the fourth gear 55 in an eccentric structure, so that both the first massage head 411 and the second massage head 421 can rotate under the action of the first driving shaft 412.

[0117] It should be noted that as Figure 3 shown, the first driving shaft 412 is arranged on the fourth gear 55 in an eccentric structure, which can make the movement range of the first massage head 411 larger.

[0118] In addition, in the massager 100 of the present application, the number of both the first massage heads 411 and the second massage heads 421 is two, and the kneading effect can be achieved by changing the distance between the first massage head 411 and the corresponding second massage head 421. In addition, the distance between the two second massage heads 421 in the X-X direction is also in the process of changing, and the massage effect can also be achieved. That is to say, the distance between the two second massage heads 421 in the left-right direction is also in the process of changing, and the massage effect can be achieved.

[0119] In the massager 100 of the present invention, by adjusting the minimum distance between the first massage head 411 and the second massage head 421, the massage intensity can be adjusted, improving the user experience of customers.
