Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a peristaltic mechanism and a massager. Background Technology

[0002] Massage heads in traditional massagers have functions such as extension, vibration, rotation, and plucking, but the massage range is relatively small, and the pressure and friction are concentrated in a localized area, failing to fully conform to the human body. Consequently, peristaltic massagers have emerged on the market. Currently, the driving mechanism of peristaltic massagers involves bending and plucking a surrounding hinged frame, thereby causing the massage head to bend.

[0003] The existing peristaltic mechanism requires a relatively long skeleton to avoid interference when adjacent joints swing in order to achieve a sufficiently large peristaltic effect. Utility Model Content

[0004] To solve the above-mentioned problems in the prior art, this utility model provides a peristaltic mechanism for a massager, including a drive motor, a transmission part, a limiting bracket, and multiple peristaltic push blocks; The drive motor is fixedly connected to the limiting bracket and drives the transmission part to rotate; The transmission part has multiple abutment shafts, adjacent abutment shafts are parallel but not on the same axis, and the abutment shafts correspond to the peristaltic push block; The peristaltic pusher includes a pushing part and a movable groove; The abutting shaft passes through the movable groove, the abutting shaft abuts against the long wall of the movable groove, and the wide wall of the movable groove makes way for the movement of the abutting shaft; The limiting bracket has a guide groove, and the end of the pushing part protrudes from the guide groove; The depth direction of the guide groove is parallel to the width direction of the movable groove, forming a guide stroke, and the peristaltic pusher slides along the guide stroke.

[0005] Furthermore, the length of the movable groove is L1, the width of the movable groove is L2, and the distance between the abutment shaft and the axis of the drive motor is L3; 0.5*L1≥L3>L2.

[0006] Furthermore, the guide groove penetrates the circumferential wall of the limiting bracket; The peristaltic pusher has two pushing parts, which protrude along the width direction of the movable groove.

[0007] Furthermore, the limiting bracket is provided with two sets of guide grooves, and the guide strokes of the two sets of guide grooves are perpendicular to each other; The length directions of the movable grooves of adjacent peristaltic push blocks are perpendicular to each other, and they are respectively set in different groups of guide grooves.

[0008] Furthermore, the distance from the axis of each contact shaft to the axis of the drive motor is equal, and the angle formed by the axes of adjacent contact shafts and the drive motor is equal.

[0009] Furthermore, a connecting boss is provided between adjacent abutting shafts; One of the abutting shafts and a connecting boss form a transmission component, and the transmission part is composed of a plurality of the transmission components; The connecting boss has a connecting hole that is not coaxial with the abutting shaft. The connecting hole is a non-rotational structure, and the end of the abutment shaft is inserted into the connecting hole and coupled thereto.

[0010] Furthermore, the abutment shaft furthest from the drive motor is abutment shaft A, which is rotatably connected to the limiting bracket, and abutment shaft A is coaxial with the drive motor.

[0011] Furthermore, the abutment shaft A is connected to a vibration function module, a telescopic function module, and a rotation function module.

[0012] Furthermore, a vibration motor is provided on the circumferential wall of the limiting bracket or the pushing part.

[0013] A massager includes the aforementioned peristaltic mechanism, comprising a housing and a silicone outer layer, wherein the drive motor and the limiting bracket are fixedly connected to the housing, and the pushing part of the peristaltic push block abuts against the inner wall surface of the silicone outer layer.

[0014] The beneficial effects of this invention are reflected in the fact that, by using the peristaltic mechanism of this application, the peristaltic massager can achieve peristaltic massage of the massage head using only a shorter skeleton structure, i.e., fewer peristaltic push blocks. At the same time, even with additional functional modules configured at the ends, the shorter skeleton structure can maintain the same overall length, achieving a better massage effect.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Reference Figures 1-11 .

[0019] A peristaltic mechanism for a massager includes a drive motor 1, a transmission part 2, a limiting bracket 3, and a plurality of peristaltic push blocks 4; The drive motor 1 is fixedly connected to the limiting bracket 3 and drives the transmission part 2 to rotate; The transmission part 2 has multiple abutment shafts 21, adjacent abutment shafts 21 are parallel but not on the same axis, and the abutment shafts 21 correspond to the peristaltic push block 4; The peristaltic pusher 4 includes a pushing part 41 and a movable groove 42; The abutting shaft 21 passes through the movable groove 42, the abutting shaft 21 abuts against the long wall of the movable groove 42, and the wide wall of the movable groove 42 makes way for the movement of the abutting shaft 21. The limiting bracket 3 has a guide groove 31, and the end of the pushing part 41 protrudes from the guide groove 31; The depth direction of the guide groove 31 is parallel to the width direction of the movable groove 42, forming a guide stroke, and the peristaltic push block 4 slides along the guide stroke.

[0020] The long wall of the movable groove 42 has two long sides; the wide wall of the movable groove 42 has two wide sides.

[0021] Currently, a type of peristaltic massager has emerged on the market. The massager head moves like a snake crawling, with different sections along its length tilting to either side, resembling an S-shape. This type of massager can better conform to the human body during the peristaltic motion, achieving a more comprehensive massage. The current drive mechanism of this type of massager uses a curved shaft passing through a frame composed of multiple hinged support sections. These support sections have elongated holes. When the curved shaft connects to the motor, some points inevitably deviate from the motor's rotation axis. During rotation, these points abut against the wall along the length of the elongated holes, causing relative rotation between adjacent support sections. The support sections then oscillate back and forth according to a certain pattern, forming a snake-like peristaltic motion. However, this mechanism, which relies on the oscillation of support sections, requires a sufficient number of support sections to achieve a complete S-shaped peristaltic effect. Therefore, the entire massage device is relatively long. Furthermore, adding other functional modules 8 to the end of the massage head would further lengthen the device, making it difficult to add additional functional modules 8 to the existing drive structure.

[0022] This application describes a peristaltic mechanism in a massager, wherein the drive motor 1 is fixedly connected to the outer shell of the massager. The drive motor 1 is mainly responsible for driving the transmission part 2 to rotate. The main shaft of the drive motor 1 can be connected to the reduction gearbox 6 to reduce the speed of the drive motor 1 and obtain greater torque, thereby preventing excessive massage stimulation. At the same time, the greater torque can prevent the massage head from getting stuck.

[0023] The transmission unit 2 is connected to the output shaft of the reduction gearbox 6 and rotates with the output shaft, such as... Figure 6 As shown, the transmission part 2 has multiple abutment shafts 21, and the axes of each abutment shaft 21 are parallel but not on the same axis.

[0024] like Figure 1 , Figure 2As shown, the peristaltic push block 4 has a movable groove 42 and a pushing part 41. The end of the pushing part 41 protrudes from the circumferential contour of the limiting bracket 3, and the end of the pushing part 41 directly abuts against the silicone outer layer 7 of the massager, thereby exerting a massage and squeezing effect. The movable groove 42 is formed in the middle of the peristaltic push block 4. The length L1 of the movable groove 42 is much greater than the width L2, and the width direction of the movable groove 42 is parallel to the direction in which the pushing part 41 protrudes from the limiting bracket 3. The abutment shaft 21 is set in the movable groove 42. Each section of the abutment shaft 21 corresponds to a peristaltic push block 4. When the axis of the abutment shaft 21 rotates to the plane in the width direction of the movable groove 42, the abutment shaft 21 abuts against the long wall surface on one side of the movable groove 42 (the long wall surface is a wall surface with two long sides). At this time, the abutment shaft 21 pushes the peristaltic push block 4 out the greatest distance. The movable groove 42 has two long wall surfaces. When abutting against the long wall surfaces on different sides, the peristaltic push block 4 moves in opposite directions. When the axis of the abutment shaft 21 rotates to the plane in the length direction of the movable groove 42, the abutment shaft 21 is close to the wide wall surface of the movable groove 42 (the wide wall surface is a wall surface with two wide sides). Since the movable groove 42 has a long length, the distance between the wide wall surfaces on both sides is far. The abutment shaft 21 cannot push the peristaltic push block 4 to move along the length direction by abutting against the wide wall surface. When the axis of the abutment shaft 21 rotates to the plane in the length direction of the movable groove 42, the peristaltic push block 4 pushes out the least distance, or even does not push out.

[0025] Specifically, the length L1 of the movable groove 42, the width L2 of the movable groove 42, and the maximum distance L3 (distance from the axis of the drive motor 1 to the edge contour of the abutment shaft 21) between the abutment shaft 21 and the axis of the drive motor 1 are all specified. The width L2 of the movable groove 42 must be at least greater than the diameter of the abutment shaft 21 to ensure that the abutment shaft 21 can be inserted into the movable groove 42 and undergo relative displacement. Minimizing the difference between the two can minimize impact noise and improve the smoothness of the movement of the peristaltic push block 4. The length L2 of the movable groove 42 should be sufficient to provide enough clearance for the abutment shaft 21, which is the diameter of the area covered by the abutment shaft 21 when rotating, i.e., the radius of the abutment shaft 21 plus the distance from the axis of the abutment shaft 21 to the axis of the drive motor 1, which is the maximum distance L3 between the axes of the abutment shaft 21 and the drive motor 1. Therefore, 0.5*L1≥L3, so that when the rotating shaft rotates to a plane parallel to the length direction of the movable groove 42, the peristaltic push block 4 remains centered without moving in any direction.

[0026] Furthermore, such as Figure 1 , 4As shown, a limiting bracket 3 is also needed to restrict the degree of freedom of the peristaltic push block 4 to prevent it from rotating with the abutment shaft 21. The limiting bracket 3 is provided with a guide groove 31, forming a guide stroke parallel to the width direction of the movable groove 42. This allows the peristaltic push block 4 to continuously move along the guide when the abutment shaft 21 pushes it, thus avoiding contact with the abutment shaft 21. The guide groove 31 penetrates the circumferential wall of the limiting bracket 3. The peristaltic pusher 4 has two pushing parts 41, which protrude along the width direction of the movable groove 42. When the abutment shaft 21 pushes out of the long wall of one side of the movable groove 42, the pushing part 41 on the same side squeezes the human skin to achieve massage.

[0027] Since the abutment shafts 21 of each section of the transmission unit 2 are not on the same axis, when one section of the abutment shaft 21 is located on the length plane of its corresponding movable groove 42 (that is, when the peristaltic pusher 4 is pushed to the farthest end), the adjacent abutment shafts 21 have not reached that position. Therefore, the distance pushed out by the peristaltic pusher 4 corresponding to the adjacent abutment shaft 21 will be relatively small. The specific movement position of the peristaltic pusher 4 depends on the distance of the abutment shaft 21 from the axis of the drive motor 1.

[0028] It should be noted that the abutment shaft 21 is not necessarily a cylindrical structure; it can also be a sphere, an ellipsoid, or even a shape close to a circle, such as a rounded rectangle.

[0029] In this embodiment, each peristaltic push block 4 slides in its own sliding formation, and adjacent peristaltic push blocks 4 will never interfere with each other. The peristaltic structure of this embodiment only requires a minimum of four peristaltic push blocks 4 to enable the massager to achieve the peristaltic effect. The peristaltic part of the massage head can be designed to be very short, so that other functional modules 8, such as the telescopic function, can be set at the front end of the massage head.

[0030] Furthermore, regarding the position of the abutment shaft 21, it is only necessary to ensure that the peristaltic pusher 4 moves continuously along the guide stroke to achieve the effect of different axes. However, if the abutment shafts 21 are arranged arbitrarily, the final motion effect formed by multiple peristaltic pushers 4 will not be similar to the effect of snake crawling. For example, if multiple abutment shafts 21 are eccentrically oriented in one direction, it will cause the peristaltic pushers 4 pushed by these abutment shafts 21 to move in the same direction at different speeds, forming a motion effect close to swaying.

[0031] This embodiment provides an optimal arrangement of the abutment shafts 21, such as... Figure 8 As shown, the distance from the axis of each abutment shaft 21 to the axis of the drive motor 1 is equal, and the axes of each abutment shaft 21 are not the same. That is to say, when viewed from the end face of the abutment shaft 21, the axis of the abutment shaft 21 only appears as a point, and the points are evenly arranged in a circular array around the axis of the drive motor 1.

[0032] In this embodiment, the coaxiality of the abutment shafts 21 is only reflected in the angle, with the offset distances being the same. For example, adjacent abutment shafts 21 form a 60-degree angle with the axis of the drive motor 1. The first abutment shaft 21 is at 0 degrees, the second at 60 degrees, and the third at 120 degrees. If the first abutment shaft 21 pushes the first peristaltic push block 4 to its farthest distance, the second peristaltic push block 4 will offset in the same direction as the first peristaltic push block 4, but with a shorter offset distance. The third peristaltic push block 4 will offset in the opposite direction to the second peristaltic push block 4, but with the same offset distance. When the drive motor 1 starts to rotate the drive unit, the first abutment shaft 21 will enter the 60-degree state, the second abutment shaft 21 will enter the 120-degree state, and the third abutment shaft 21 will enter the 180-degree state. At this time, the third peristaltic push block 4 reaches its maximum offset distance, but its direction is opposite to that of the first peristaltic push block 4 initially. Similarly, during the rotation of the transmission unit 2, the angle of the previous abutment shaft 21 will always enter the angle before the rotation of the next abutment shaft 21, so that each creeping push block 4 can be offset to the same distance in sequence. This achieves a serpentine creeping effect.

[0033] Example 2 like Figure 5 As shown, the limiting bracket 3 is provided with two sets of guide grooves 31, and the guide strokes of the two sets of guide grooves 31 are perpendicular to each other. The length directions of the movable grooves 42 of the adjacent peristaltic push blocks 4 are perpendicular to each other, and they are respectively set in different groups of guide grooves 31.

[0034] As mentioned in Embodiment 1, the existing structure is formed by hinged multiple support parts, and each support part must swing simultaneously. The swing angle of the subsequent support part is to avoid further swing of the preceding support part and prevent the support parts from interfering with each other. Therefore, each support part can only swing in one plane. For example, if the support part swings in the horizontal direction, it cannot swing in the vertical direction at the same time.

[0035] In this embodiment, two sets of guide grooves 31 are provided, and the guide strokes of the two sets of guide grooves 31 are perpendicular to each other. The length direction of the movable groove 42 of the peristaltic push block 4 only needs to be parallel to the guide stroke of one of the guide grooves 31. Adjacent peristaltic push blocks 4 are arranged in different sets of guide grooves 31.

[0036] The peristaltic push blocks 4 within the two sets of guide grooves 31 are identical; they are still driven by the abutment shaft 21 to move the long wall of the movable groove 42. This achieves peristalsis in two directions, resulting in a more comprehensive massage effect.

[0037] Example 3 Reference Figure 7 .

[0038] In Embodiment 1, an optimal arrangement of the abutment shafts 21 is provided. However, connecting the abutment shafts 21 arranged in this way into a single drive unit requires increasing the diameter of the abutment shafts 21 so that different abutment shafts 21 can have overlapping areas. Increasing the diameter of the abutment shafts 21 will increase production costs, and the width and length of the movable groove 42 also need to be increased. However, the size of the massager is limited and it is impossible to increase the size of the movable groove 42 indefinitely. Therefore, this embodiment provides a structure that reduces the size of the abutment shafts 21 without increasing costs as much as possible.

[0039] First, it should be noted that the diameter of the abutment shaft 21 must be thick enough because the circumferentially arranged abutment shaft 21 has a rotating structure, making it difficult to open the mold. Therefore, in this embodiment, the drive part is disassembled into multiple parts, injection molded, and finally spliced ​​together to form the transmission part 2.

[0040] Specifically, one end of the abutment shaft 21 is provided with a connecting boss 22. The connecting boss 22 and the connecting shaft are directly injection molded to form a transmission component. The connecting boss 22 has a connecting hole 221 arranged non-coaxially with the abutment shaft 21, and the connecting hole 221 is a non-rotational structure, which can be set as an elongated strip. After the abutment shaft 21 is inserted into the connecting hole 221 and coupled with it, the two generate a definite relative angle, that is, the relative angle between adjacent abutment shafts 21 is determined. During splicing, it is not necessary to control the relative angle between abutment shafts 21 separately; simply inserting the abutment shaft 21 directly into the connecting hole 221 will form the above-mentioned optimal abutment shaft 21 arrangement.

[0041] Example 4 Reference Figure 9 , Figure 10 .

[0042] The abutment shaft 21 furthest from the drive motor 1 is abutment shaft A211. Abutment shaft A211 is rotatably connected to the limiting bracket 3, and abutment shaft A211 is coaxial with the drive motor 1.

[0043] The abutment shaft A211 is connected to the limit bracket 3, which supports the transmission part 2, effectively preventing the transmission part 2 from tilting and increasing the overall stability of the transmission part 2.

[0044] Furthermore, a functional module 8 is connected to the end of the abutment shaft A211. The functional module 8 can be a vibration module, enabling the massage head of the massager to have a vibration effect. Functional module 8 can be a telescopic function module 8. The abutment shaft A211 replaces the main shaft of a conventional telescopic mechanism motor. For example, the telescopic mechanism includes an output shaft, a sliding sleeve, and a limiting sleeve. The abutment shaft 21 connects to the output shaft, which has an inclined groove. The sliding sleeve fits onto the output shaft and contains balls that abut against the side wall of the groove. The limiting sleeve is fixedly connected to the limiting bracket 3 and fits onto the sliding sleeve, restricting its rotation. The abutment shaft A211 drives the output shaft to rotate, and the wall of the groove pushes the sliding sleeve to move.

[0045] Functional module 8 can be configured as a rotational functional module 8. The abutment shaft A211 is connected to an output shaft with a bending angle. The end of the output shaft is eccentric to the abutment shaft A211. When the abutment shaft A211 drives the output shaft to rotate, the end of the output shaft will form a circular trajectory rotating around the axis of the abutment shaft A211.

[0046] Example 5 Reference Figure 6 .

[0047] The circumferential wall of the limiting bracket 3 or the pushing part 41 is provided with a vibration motor 5.

[0048] In this embodiment, a vibration motor 5 is installed in the circumferential wall, so that the middle section of the massager has a vibration sensation. Unlike most massagers where the vibration function is located at the front end, the vibration motor 5 at the front end has difficulty transmitting the vibration effect to the middle section of the massager. However, by installing the vibration motor 5 in the circumferential wall of the limiting bracket 3 or the pushing part 41, the vibration sensation in the middle section can be coordinated with the peristaltic area in this application, increasing the vibration effect during peristaltic massage.

[0049] The effect of placing the motor 5 in the limiting bracket 3 versus the pushing part 41 is somewhat different. Placing it in the limiting bracket 3 allows the entire peristaltic mechanism to have a more obvious vibration, so that each pushing part 41 has a vibration; while placing the vibration motor 5 in the pushing part 41 will make a certain pushing part 41 have a noticeable vibration, and the human body can feel the constantly changing vibration as the pushing part 41 moves.

[0050] Example 6 Reference Figure 11 .

[0051] A massager includes the peristaltic mechanism of the above embodiment, and also includes a housing and a silicone outer layer 7. The drive motor 1 and the limiting bracket 3 are fixedly connected to the housing, and the pushing part 41 of the peristaltic push block 4 abuts against the inner wall surface of the silicone outer layer 7.

[0052] Multiple push parts 41 continuously slide and squeeze the silicone outer layer 7 of the massager in a fixed order (the arrangement order of the abutment shaft 21), and the silicone outer layer 7 contacts the human body to achieve the massage function.
