Description

Technical Field

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

[0002] There are various types of massagers on the market, such as vibrating, telescopic, suction, and tapping types, each with its own characteristics. Many massagers integrate multiple functions.

[0003] Tapping massagers typically use a motor to drive an eccentric wheel, causing the support body of the tapping device to swing, thus achieving the tapping action.

[0004] It is understood that there are currently no massagers that can perform pinching motions. Pinching massagers can mimic the repeated pinching motions of fingers, providing users with a novel massage experience. Utility Model Content

The transmission sleeve is slidably connected to the guide bracket, and the sliding direction is parallel to the axial direction of the transmission sleeve; The massage fingers are multiple in number and are arranged around the transmission sleeve and hinged in the guide bracket, so that the massage fingers swing toward or away from the axis of the transmission sleeve. The drive motor drives the transmission shaft to rotate, so that the transmission sleeve pushes the massage fingers to swing. The drive motor is fixedly installed inside the housing, and the silicone layer covers the housing, the massage fingers, and the transmission mechanism.

[0006] Furthermore, the massage finger has a bend along its own length.

[0007] Furthermore, the circumferential wall of the drive shaft is provided with reciprocating thread grooves; A sliding plate is rotatably provided inside the transmission sleeve; The sliding plate is coupled to the reciprocating threaded groove so that the transmission shaft and the transmission sleeve form a reciprocating screw engagement.

[0008] Furthermore, the tip of the massage finger is hinged to the guide bracket; The transmission sleeve and the massage finger are connected by a movable connecting rod, and the two ends of the movable connecting rod are respectively hinged to the transmission sleeve and the massage finger; The hinge position between the movable connecting rod and the massage finger is the first hinge point, and the hinge position between the massage finger and the guide bracket is the second hinge point. The first hinge point is parallel to the hinge axis at the second hinge point.

[0009] Furthermore, the massage finger is hinged to the guide bracket; The massage finger tip abuts against the transmission sleeve in both forward and backward directions, and the abutment position slides relative to each other.

[0010] Furthermore, the massage finger is divided into a connecting section and a deformation section along its length. The connecting section is used to connect the guide bracket and the transmission sleeve. The deformation section provides support for the silicone layer and can rotate relative to the connecting section.

[0011] Furthermore, the deformable segment is hinged to the connecting segment, and a torsion spring is provided between the deformable segment and the connecting segment to determine the relative position of the deformable segment and the connecting segment.

[0012] Furthermore, the silicone layer wraps around the end of the massage finger and extends to form a flexible patting surface.

[0013] Furthermore, a telescopic column is fixedly provided at the end of the transmission sleeve; The silicone layer encapsulates the telescopic column and forms a deformation region around the circumferential wall of the telescopic column, so that the silicone layer has a telescopic deformation along the axial direction of the telescopic column.

[0014] Furthermore, a rolling column is fixedly connected to the end of the drive shaft, the front end of the rolling column protrudes from the massage finger, and a plurality of balls are provided on the axial wall of the front end of the rolling column, the balls protruding from the circumferential wall of the rolling column.

[0018] 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.

[0019] It should be noted that the pinching massager in this application does not mean that the function of the massager is pinching, but rather that the massage structure in this application massages using a pinching motion of the fingers. In this motion mode, the massage fingers can also perform a patting motion.

[0020] Example 1 Reference Figures 1-9 .

[0021] A pinch-type massager includes: a drive motor 1, massage fingers 2, a transmission mechanism 3, a housing 4, and a silicone layer 5; The transmission mechanism 3 includes a transmission shaft 31, a transmission sleeve 32, and a guide bracket 33; The transmission sleeve 32 is sleeved on the transmission shaft 31 and slides relative to the transmission shaft 31. The transmission sleeve 32 and the transmission shaft 31 form an inclined surface fit so that the rotational torque is converted into a thrust parallel to the axis of the transmission sleeve 32. The transmission sleeve 32 is slidably connected to the guide bracket 33, and the sliding direction is parallel to the axial direction of the transmission shaft 31; The massage fingers 2 are multiple, and the multiple massage fingers 2 are arranged around the transmission shaft 31 and hinged in the guide bracket 33, so that the massage fingers 2 swing toward or away from the axis of the transmission sleeve 32. The drive motor 1 drives the transmission shaft 31 to rotate, so that the transmission sleeve 32 pushes the massage finger 2 to swing. The drive motor 1 is fixedly installed inside the housing 4, and the silicone layer 5 encloses the housing 4, the massage finger 2, and the transmission mechanism 3.

[0022] In existing tapping massagers, the tapping body only performs tapping motions in one direction. Most have only one tapping body that rotates around a hinge axis, repeatedly tapping the body. Massagers with two tapping bodies also exist, but the two bodies move along the same trajectory, merely alternating and performing the same tapping motion, thus only achieving localized tapping. Furthermore, existing technologies do not include massage devices that mimic the pinching motion of fingers.

[0023] This application provides a massager capable of simulating pinching motions, comprising multiple massage fingers 2 that move synchronously via a transmission mechanism 3. It is recommended to have three massage fingers 2 to simulate the pinching motion formed by the opening and closing of the middle finger, index finger, and thumb, creating a three-point pinch. This is because simple mechanical structures cannot achieve the precise movements of human fingers, while three-point pinching automatically brings the object being pinched closer to the center of the three points, similar to the self-centering effect of a three-jaw chuck in machining.

[0024] The transmission mechanism 3 specifically includes a transmission shaft 31, a transmission sleeve 32, and a guide bracket 33. The transmission shaft 31 is fixedly connected to the drive motor 1 coaxially, and the drive motor 1 drives the transmission shaft 31 to rotate.

[0025] The drive shaft 31 can be arranged vertically or horizontally, as an alternative, providing a new arrangement of the drive motor 1 for massagers of different shapes; The transverse arrangement means that the transmission shaft 31 is perpendicular to the guiding direction of the guide bracket 33, and the axis of the drive motor 1 is parallel to the axis of the transmission shaft 31. In this structural state, the transmission shaft 31 can be configured as a cam structure, or it can be eccentrically positioned with respect to the drive motor 1 and used as an eccentric wheel. The axial wall surface of the transmission shaft 31 abuts against the end face of the transmission sleeve 32, thereby allowing the transmission sleeve 32 to slide along the guide bracket 33.

[0026] Vertical arrangement means that the axis of the drive shaft 31 is parallel to the guiding direction of the guide bracket 33, and the drive motor 1 is fixedly connected coaxially to the drive shaft 31. The side wall of the drive shaft 31 is provided with threaded grooves 313, and the drive sleeve 32 is sleeved on the drive shaft 31 to form a lead screw engagement. It should be noted that the distance that the drive sleeve 32 needs to move is very short and it needs to reciprocate. Therefore, it is difficult to achieve reciprocating motion by the forward and reverse rotation of the drive motor 1. For this reason, the drive shaft 31 can be set as a reciprocating lead screw. The characteristic of the reciprocating lead screw is that its circumferential wall has two threaded grooves 313 with the same pitch and opposite directions. The two ends of the two threaded grooves 313 are connected by a transition curve to form a reciprocating threaded groove 313. Correspondingly, the drive sleeve 32 is provided with a sliding plate 314 that engages with the reciprocating lead screw. The slider 314 is an important component in reciprocating screw drives. It is installed in the threaded groove 313. When the slider 314 moves to one end of the threaded groove 313, it can rotate by abutting the transition curve of the threaded groove 313, thus entering the threaded groove 313 in the correct direction. Reciprocating screw drive technology is very familiar, so it will not be described in detail here. Alternatively, the drive shaft 31 can be fitted with only a ring-shaped groove 311 on its circumferential wall. However, the axis of the ring-shaped groove 311 must be inclined to the axis of the drive shaft 31, so that when the drive shaft 31 rotates only half a turn, the drive sleeve 32 will slide to its farthest end, and when the drive shaft 31 continues to rotate half a turn, the drive sleeve 32 will slide to the other end. In this case, the drive sleeve 32 only needs to have a sliding protrusion 312, which can be in the form of a ball bearing 71, making the transmission smoother.

[0027] In this embodiment, two specific structures are provided to explain how the transmission sleeve 32 drives the massage finger 2 to swing.

[0028] like Figure 2As shown, the front end of the massage finger 2 is hinged to the guide bracket 33. The transmission sleeve 32 and the massage finger 2 transmit force through a movable connecting rod 321. The two ends of the movable connecting rod 321 are respectively hinged to the transmission sleeve 32 and the massage finger 2. The end of the massage finger 2 that is actually used for massage and is close to the massage finger 2 is the end of the massage finger 2, and the opposite end is the front end.

[0029] Multiple guide shafts can be installed in the guide bracket 33. The guide shafts are connected to both ends of the guide bracket 33 along its length. The length direction of the guide bracket 33 is also the sliding direction of the transmission sleeve 32, and it is also the axis direction of the transmission shaft 31 and the transmission motor. In other words, these directions are parallel to each other. The massage finger 2 is hinged to the end of the guide bracket 33 (the end away from the drive motor 1).

[0030] During the sliding process of the transmission sleeve 32, one end of the movable link 321 moves with the sleeve, while the other end is restricted by the massage finger. When the transmission sleeve 32 moves closer to the massage finger 2, the movable link 321 pushes the massage finger 2 to swing around the hinge axis at the second hinge point. Simultaneously, the hinge axes at the first and second hinge points are parallel, allowing the movable link to change its angle with the massage finger 2 during its swing, thus preventing the movable link 321 from interfering with the swing of the massage finger 2. Furthermore, the movable link 321 and the transmission sleeve 32 are also hinged (the hinge direction is the same as the hinge direction between the movable link 321 and the massage finger 2), allowing the movable link 321 to rotate relative to the transmission sleeve 32, enabling one end of the movable link 321 to move with the massage finger 2. At the same time, due to the hinge, the movable link 321 can transmit thrust when the transmission sleeve 32 is close to the massage finger 2, and also transmit pull when the transmission sleeve 32 is away from the massage finger 2, so that the massage finger 2 can swing in the opposite direction.

[0031] like Figure 3 As shown, in another specific structure, the massage finger 2 is hinged to the guide bracket 33; The front end of the massage finger 2 abuts against the transmission sleeve 32 in both forward and backward directions, and the abutment position slides relative to each other.

[0032] The massage finger 2 remains hinged to the guide bracket 33, thus limiting the movement trajectory of the massage finger 2. In this structure, the massage finger 2 and the transmission sleeve 32 do not need to be connected by a movable connecting rod 321; they only need to abut against each other. For example, the massage finger 2 is provided with an abutting groove 21, and the transmission sleeve 32 has a sliding protrusion 312. The sliding protrusion 312 is disposed inside the abutting groove 21. When the transmission sleeve 32 is close to the massage finger 2, the sliding protrusion 312 abuts against one side wall of the groove 21; when the transmission sleeve 32 is away from the massage finger 2, the sliding protrusion 312 abuts against the other side wall of the groove 21, thereby providing thrust to the massage finger 2 in two directions, allowing the massage finger 2 to swing in two directions. The sliding protrusion 312 translates, and the massage finger 2 rotates. The sliding protrusion 312 can slide relative to the massage finger 21, thereby adapting to the relative changes in their positions when the massage finger 2 rotates.

[0033] This application provides a novel type of massager that mimics the pinching motion of fingers, enriching the functionality of massagers on the market and providing users with different forms of massage stimulation. In addition, the multiple massage fingers 2 in this application can also be connected to a flexible material to function as a tapping massager, enabling large-area tapping and overcoming the shortcomings of existing tapping massagers which have small tapping areas and can only tap locally.

[0034] Example 2 The massage finger 2 has a bend along its own length, and the plane of the angle formed by the bend is parallel to the plane of the swing angle of the massage finger.

[0035] like Figure 1-9 As shown, a straight line in a plane can bend in two directions. In this embodiment, the massage finger 2 also includes a state in which the massage finger 2 bends in two directions. Multiple massage fingers 2 can bend in directions away from each other to form a “)(” structure, so that the ends of the massage fingers 2 are in an expanded state. When the massage fingers 2 in the expanded state pinch, the middle sections of the massage fingers 2 are close to each other to pinch the object. During the pinching process, not only radial force but also axial force are generated, so that the massager produces a pinching effect of pushing towards the pinched object and gradually sliding away from the pinched object.

[0036] like Figure 10 As shown, the massage fingers 2 can also bend towards each other to form a “()” structure. The ends of the massage fingers 2 converge, and at this time, the massage fingers 2 can provide greater pressure to the object being pinched. The local pinching is achieved through the ends of the massage fingers 2, thereby better realizing the “pinching” action and achieving the pinching and pressing effect.

[0037] Example 3 like Figure 6 , Figure 7 As shown.

[0038] The massage finger 2 is divided into a connecting section 22 and a deformation section 23 along its length. The connecting section 22 is used to connect the guide bracket 33 and the transmission sleeve 32. The deformation section 23 provides support for the silicone layer 5 and can rotate relative to the connecting section 22.

[0039] The size of the object being pinched is uncertain for the pinching action. If the massage finger 2 swings arbitrarily, the continuous application of power by the drive motor 1 may injure the user or cause the drive motor 1 to seize up, damaging the massager. Furthermore, when the massage finger 2 simulates the pinching action of a finger, it also has the slender shape of a finger. Slender parts have weak bending resistance and may break or bend when subjected to excessive force.

[0040] In this embodiment, the massage finger 2 is configured as a two-section structure, one section being a connecting section 22. The connecting section 22 can be simply made of plastic and possesses sufficient rigidity. The connecting section 22 connects to the guide bracket 33 and the transmission sleeve 32, transmitting the force to the deformation section 23. The deformation section 23 supports the silicone layer 5; this is the actual location for massaging the human body. The deformation section 23 and the connecting section 22 are not rigidly connected. For the connecting section 22, rotation of the drive motor 1 by a certain angle will cause the connecting section 22 to swing to the corresponding position. However, the position of the deformation section 23 does not necessarily correspond to the angle of the drive motor 1.

[0041] Specifically, the deformable segment 23 can be directly set as a spring piece, which can avoid the movement of the drive motor 1 by deforming itself. The end of the massage finger 2 (which is also the end of the deformable segment 23, with the end of the deformable segment 23 connected to the connecting segment 22 as the front end) is fixed. At this time, the connecting part continues to swing, the front end of the deformable segment 23 is subjected to force and moves with the connecting part. The deformable segment 23 bends to provide space for the connecting part to continue to swing.

[0042] The deformation segment 23 can also be set as a rigid part. The deformation segment 23 is hinged to the connecting segment 22, and a torsion spring 24 is sleeved at the hinge position. The elastic force provided by the torsion spring 24 can provide support for the massage finger 2, so that the force of the drive motor 1 is transmitted to the deformation segment 23. At the same time, the torsion spring 24 can deform when subjected to excessive force, so that the deformation segment 23 and the connecting segment 22 rotate relative to each other.

[0043] In this embodiment, the massage finger 2 is configured as a two-segment structure consisting of a deformable segment 23 and a connecting segment 22. The connecting segment 22 is responsible for transmitting power, while the deformable segment 23 is responsible for pinching. When the size of the object being pinched is too large, the end of the massage finger 2 cannot converge, and the load on the drive motor 1 continuously increases until the force provided by the drive motor 1 exceeds the elastic force of the deformable segment 23, causing relative movement between the deformable segment 23 and the connecting segment 22. Thus, the end of the massage finger 2 (that is, the end of the deformable segment 23) remains in contact with the object being pinched, and the connecting segment 22 swings based on the deformation of the deformable segment 23, thereby preventing the drive motor 1 from jamming; it also limits the maximum pinching force (the maximum pinching force is the elastic force at the position of the deformable segment 23) to prevent injury to the user.

[0044] Example 4 like Figure 1 As shown.

[0045] The silicone layer 5 wraps around the end of the massage finger 2 and extends to form a flexible patting surface 51.

[0046] In this embodiment, after the silicone layer 5 wraps around the end of the massage finger 2, a thinner silicone layer 5 extends along the length of the massage finger 2 to form a flexible patting surface 51. The patting principle of the flexible patting surface 51 is similar to that of a whip, with the massage finger 2 acting as the handle of the whip. When the massage finger 2 swings, the angular velocity of the flexible patting surface 51 is faster, thus patting the skin.

[0047] Example 5 The silicone layer 5 covers the end of the massage finger 2 and has protruding massage particles.

[0048] The silicone layer 5 wraps around the end of the massage finger 2. The end of the silicone layer 5 is not a smooth transition but has multiple protruding massage particles, making the part of the silicone layer 5 that contacts the skin relatively rough to increase friction and prevent slippage when pinching.

[0049] Example 6 like Figure 8 As shown.

[0050] The end of the transmission sleeve 32 is fixedly provided with a telescopic column 6; The silicone layer 5 encapsulates the telescopic column 6 and forms a deformation region around the circumferential wall of the telescopic column 6, so that the silicone layer 5 has a telescopic deformation along the axial direction of the telescopic column 6.

[0051] First, it should be noted that the telescopic column 6 does not need to have a telescopic function itself; rather, it is sufficient for the massager to have a telescopic function.

[0052] In this application, the transmission sleeve 32 continuously slides along the axial direction of the transmission shaft 31 during operation. Therefore, the telescopic column 6 only needs to be simply fixed on the end face of the transmission sleeve 32 to perform telescopic actions (i.e., the end of the telescopic column 6 moves closer to and away from the drive motor 1). The silicone layer 5 covering the position of the telescopic column 6 should be provided with a deformation area to avoid the silicone layer 5 from hindering the movement of the telescopic column 6.

[0053] Furthermore, the silicone layer 5 at the end of the telescopic column 6 can be configured as a flat structure, so that it vertically pats the skin of the object being pinched during the telescopic column 6's extension and retraction.

[0054] Alternatively, the telescopic column 6 can be set as a solid hemispherical head, in which case the massage finger 2 can be set as in Example 3 to realize the patting function and pat the skin around the telescopic column.

[0055] Example 7 like Figure 9 As shown.

[0056] The end of the drive shaft 31 is fixedly connected to a rolling column 7. The front end of the rolling column 7 protrudes from the massage finger 2. A ball bearing 71 is provided on the axial wall of the front end of the rolling column 7. The ball bearing 71 protrudes from the circumferential wall of the rolling column 7. The silicone layer 5 encloses the rolling column 7, and the ball bearing 71 presses against the silicone layer 5 to deform it.

[0057] In this application, the drive shaft 31 rotates continuously during operation, and the rolling column 7 is directly fixedly connected to the drive shaft 31. Multiple balls 71 are provided on the circumferential wall of the drive shaft 31. As the rolling column 7 rotates with the drive shaft 31, the balls 71 roll and contact the inner wall of the silicone layer 5, thereby indirectly performing rolling massage on the human skin.

[0058] The silicone layer 5 covering the roller ball 71 can be made thinner to increase the massage effect of the roller ball 71 on the skin.
