Description

Technical Field

[0001] The present application belongs to the technical field of massage equipment, and in particular relates to a massager for massaging the waist or waist-hip area. Background Art

[0002] Currently, massagers mainly used for massaging the waist or waist and hip areas on the market generally adopt a massage movement with a V-shaped hinge structure, so that when the massager is placed on the waist or waist and hip areas of the human body, the massage head on the massage movement can automatically lean towards the waist or hips of the human body, making it easier for the massage head to fit and maintain contact with the human body, effectively ensuring the massage strength and fit of the massage head, and improving the massage effect.

[0003] Existing V-shaped massage mechanisms primarily use torsion springs to provide the elastic force pulling the left and right massage mechanisms together, allowing them to fold together like a hinge. However, because the opening angle of the two massage mechanisms depends on the strength of the torsion springs, allowing the torsion springs to freely retract and expand is necessary to maintain the hinge-like folding force between the two massage mechanisms and achieve the effect of automatically leaning against the body. This limits the massager's use cases. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a massager to solve the technical problem in the prior art that the opening angle of the V-shaped massage movement cannot be fixed, which limits the use scenarios of the massager.

[0005] To achieve the above-mentioned object, the technical solution adopted in the present application is as follows: providing a massager, comprising a left massage movement and a right massage movement, wherein an elastic mechanism and a clutch assembly are provided between the left massage movement and the right massage movement, wherein the elastic mechanism is used to fold or reset the left massage movement and the right massage movement in a hinge-like manner;

[0006] The clutch assembly is used to lock or unlock the opening angles of the left massage movement and the right massage movement, and the clutch assembly includes a clutch shaft and a travel disk respectively provided on the left massage movement and the right massage movement, the clutch shaft is provided with a knob and a first elastic member, the knob is used to abut against the travel disk and move along the contour of the travel disk; the contour of the travel disk includes a movable groove for the knob to move and a positioning groove for limiting the movement of the knob, and a blocking protrusion is provided between the movable groove and the positioning groove;

[0007] The clutch shaft is configured to enable the turn button to change its posture and cross the blocking protrusion during forward rotation to switch between the movable groove and the positioning groove; the first elastic member is used to drive the clutch shaft to rotate in the reverse direction after forward rotation to restore the posture of the turn button.

[0008] The beneficial effect of the massager provided by the present application is that, compared with the prior art, the V-shaped massage movement structure in the massager is improved, and an elastic mechanism and a clutch assembly are provided between the left massage movement and the right massage movement of the massager. The elastic mechanism is used to enable the left massage movement and the right massage movement to be folded or reset to each other in a hinge shape, so that the massager can maintain contact with the human body during normal use, effectively ensuring the massage strength and massage effect.

[0009] The clutch assembly acts as an opening angle lock for the left and right massage movements, locking or unlocking the opening angle between the left and right massage movements. When the left and right massage movements of the massager are opened to a set angle, the clutch assembly automatically locks the opening angle, allowing the massager to be used at the locked opening angle. The clutch assembly can then be used to unlock the locked opening angles of the left and right massage movements, allowing the massager to return to normal use. This expands the use scenarios of this type of massager and improves its performance.

[0010] The specific structure of the turn buckle is improved. The turn buckle is provided with a cutout, which is used to avoid the blocking protrusion so that the turn buckle can cross the blocking protrusion and the turn buckle can switch positions between the movable groove and the positioning groove.

[0011] The contour structure of the travel disc is improved. The travel disc has multiple positioning grooves, and adjacent positioning grooves are separated by movable grooves separated by blocking protrusions. This allows the rotary knob to selectively engage with different positioning grooves, thereby achieving different gear shifts.

[0012] The connection structure between the massagers has been improved. The travel discs are located on both sides of the connection end of the right massage movement. The connection end of the left massage movement is equipped with a connection seat for mounting the clutch shaft. The connection seat supports the clutch shaft on the travel disc, allowing the knob on the clutch shaft to fit snugly on the travel disc. In this way, the clutch shaft can be supported by the connection seat, so that the knob on the clutch shaft can align with the position of the travel disc, allowing the knob to fit snugly on the travel disc and cooperate with the contour of the travel disc to achieve the corresponding unlocking or locking operation.

[0013] In one embodiment, the connecting base is provided with a fixing buckle, and the first elastic member is a torsion spring, which is wound and fixed on the clutch shaft, and the extended end of the first elastic member is fixed to the fixing buckle. The force of the first elastic member enables the rotating buckle to maintain a position against the blocking protrusion under normal conditions, thereby ensuring the locking effect of the opening angle of the left and right massage movement.

[0014] In one embodiment, a limit block is further provided on the clutch shaft, and a stop protrusion is provided on the connecting seat that cooperates with the position of the limit block. The limit block and the stop protrusion cooperate with each other to limit the rotation angle of the clutch shaft, thereby limiting the rotation range of the clutch shaft, effectively improving the posture change accuracy of the rotary buckle, and thereby improving the stability of the unlocking or self-locking operation of the clutch assembly.

[0015] In one embodiment, the travel disc is a symmetrical component, comprising a sector-shaped disc body. A plug-in shaft is provided on the travel disc, which is vertically positioned and secured to the side of the right massage mechanism by the plug-in shaft. The sector-shaped edge of the travel disc includes the positioning slot and the movable slot. This symmetrical component improves the versatility of the accessory and reduces production costs. The positioning slot and movable slot provided on the sector-shaped edge of the travel disc enable a tight fit with the rotary buckle, enabling unlocking or self-locking operations.

[0016] In one embodiment, the positioning groove is disposed on the perpendicular midline of the travel disc, the blocking protrusions are located on either side of the positioning groove, and the movable grooves extend from the blocking protrusions on either side to either side of the fan-shaped edge of the travel disc. In this manner, a self-locking operation can be achieved when the left and right massage mechanisms are opened at an angle close to 180 degrees.

[0017] In one embodiment, the elastic mechanism is a second elastic member sleeved on the insertion shaft, the second elastic member being a torsion spring, one end of the second elastic member being fixed to the left massage mechanism, and the other end of the second elastic member being fixed to the right massage mechanism. Thus, the elastic mechanism and the connection structure between the left and right massage mechanisms are compactly matched, which helps save internal space and effectively provides a folding force for the left and right massage mechanisms, so that during use, the left and right massage mechanisms can automatically lean against the human body, effectively ensuring the massage strength and massage effect of the massage heads.

[0018] In one embodiment, an operating portion for manually operating the clutch shaft to rotate is provided on one end of the clutch shaft, so that the unlocking operation can be achieved by manually rotating the clutch shaft, which is convenient and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0037] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0038] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] The present invention provides a novel massager that breaks with the design philosophy of conventional V-shaped massagers, which dictate that the left and right massage mechanisms maintain a hinge-like folding force to ensure they remain against the body during use, ensuring a positive massage effect. However, because the V-shaped massage mechanism lacks a fixed opening angle, for example, the left and right massage mechanisms cannot be locked when opened to nearly 180 degrees, limiting the use of this type of massager.

[0041] To address this issue, the V-shaped massage mechanism in the massager has been improved. When the V-shaped mechanism is unfolded to a certain angle, it can automatically lock. For example, the two massage mechanisms can automatically lock when the opening angle approaches 180 degrees. This effectively expands the massager's application scenarios. This is now explained in detail.

[0042] Please also refer to Figure 1 and Figure 2A massager with a V-shaped massage movement includes a symmetrically arranged left massage movement 100 and right massage movement 200. An elastic mechanism is provided between the left massage movement 100 and the right massage movement 200. This elastic mechanism is used to fold or reset the left massage movement 100 and the right massage movement 200 like a hinge, allowing the left massage movement 100 and the right massage movement 200 to stay close to each other like a hinge, thereby allowing the massage heads installed on each massage movement to better fit the human body and ensure massage intensity.

[0043] A clutch assembly is also located between the left and right massage movements 100, 200. This clutch assembly is used to lock the opening angle between the left and right massage movements 100, 200. The clutch assembly comprises at least a clutch shaft 1 and a travel disc 2, which are respectively located on the left and right massage movements 100, 200. For example, the clutch shaft 1 can be located on the left massage movement 100, and the travel disc 2 can be located on the right massage movement 200. The respective positions of the two can also be interchanged, and this is not specifically limited here.

[0044] Please also refer to Figure 2 、 Figure 3 and Figure 4 , a turn button 11 and a first elastic member 12 are provided on the clutch shaft 1, and the travel disk 2 is matched with the turn button 11 on the clutch shaft 1. The turn button 11 on the clutch shaft 1 is used to abut against the travel disk 2 and can move along the contour on the travel disk 2. The contour on the travel disk 2 includes a movable groove 21 for the movement of the turn button 11 and a positioning groove 22 for limiting the movement of the turn button 11, and a blocking protrusion 23 is also provided between the movable groove 21 and the positioning groove 22. This means that during the mutual folding movement of the left massage movement 100 and the right massage movement 200, the turn button 11 provided on the clutch shaft 1 can move relative to the travel disk 2. The turn button 11 can fit on the surface of the travel disk 2 and move or be restricted along the contour on the surface of the travel disk 2.

[0045] The contoured configuration of the travel disc 2 can be understood as a configuration in which the movable groove 21 is larger than the positioning groove 22, allowing the knob 11 to move within the movable groove 21. For example, under the action of the aforementioned elastic mechanism, the left and right massage mechanisms 100 and 200 can freely move toward or away from each other within a certain angular range. For example, when the angle between the left and right massage mechanisms 100 and 200 is within the range of 0 to 170 degrees, the left and right massage mechanisms 100 and 200 can freely move toward or away from each other. At this point, the knob 11 on the clutch shaft 1 moves within the movable groove 21 on the travel disc 2.

[0046] Similarly, blocking protrusions 23 are provided on both sides of the positioning groove 22, or at least on the side closest to the movable groove 21. When the knob 11 is located within the positioning groove 22, it is blocked by the blocking protrusions 23, thereby being restricted by the blocking protrusions 23 and having its range of movement reduced, or being fixed within a predetermined smaller range. As an example, the clutch assembly can be locked so that when the opening angle of the left massage movement 100 and the right massage movement 200 approaches 180 degrees, the knob 11 is constrained in the positioning groove 22 of the travel disc 2 and cannot move, thereby locking the opening angle of the left massage movement 100 and the right massage movement 200.

[0047] Please also refer to Figure 5 、 Figure 6 and Figure 7 (F1 in the figure represents the direction of forward rotation of the clutch shaft, and F2 represents the direction of reverse rotation of the clutch shaft.) Regarding the locking mechanism between the left massage movement 100 and the right massage movement 200, the clutch shaft 1 is configured to cause the knob 11 to change its position and cross the blocking protrusion 23 during forward rotation, thereby switching its position between the movable groove 21 and the positioning groove 22. This means that forward rotation of the clutch shaft 1 synchronously drives the knob 11 to rotate forward, changing its position so that the knob 11 can cross the blocking protrusion 23 in its changed position, thereby enabling the knob 11 to switch from the movable groove 21 to the positioning groove 22, or from the positioning groove 22 to the movable groove 21, thereby achieving a locking or unlocking operation.

[0048] Among them, the above-mentioned "forward rotation of the clutch shaft 1" can be manual operation of the clutch shaft 1 to rotate to implement the unlocking operation; or, it can be achieved by pushing the spin buckle 11 through the blocking protrusion 23 to drive the clutch shaft 1 to rotate forward as a whole, thereby realizing an automatic locking operation.

[0049] The first elastic member 12 is used to drive the clutch shaft 1 to rotate in the reverse direction after forward rotation, so that the spindle 11 can return to its original position and abut against the blocking protrusion 23. This means that during forward rotation of the clutch shaft 1, the force of the first elastic member 12 is not restrained; conversely, the clutch shaft 1 is constrained by the force of the first elastic member 12, making it difficult for external forces to drive the clutch shaft 1 to rotate further in the reverse direction.

[0050] Regarding the "posture" of the turn buckle 11, in the embodiment of the present application, the turn buckle 11 has at least two postures. The first posture can be used to maintain contact with the blocking protrusion 23; the second posture can be used to avoid the blocking protrusion 23, so that the turn buckle 11 can cross over the blocking protrusion 23 and achieve position switching between the movable groove 21 and the positioning groove 22. In this way, under the action of the first elastic member 12, the turn buckle 11 is always in the first posture, which can be used to contact with the blocking protrusion 23 to achieve locking, such as Figure 7When the knob 11 rotates forward with the clutch shaft 1, the knob 11 rotates from the first posture to the second posture, as shown Figure 5 and Figure 6 As shown, the second posture can be used to avoid and cross the blocking protrusion 23 to achieve unlocking or self-locking operation.

[0051] Specifically, the working principle of the clutch assembly is:

[0052] like Figure 3 As shown, the left massage movement 100 and the right massage movement 200 can be freely folded or opened with each other within a set angle range. At this time, the rotary buckle 11, under the action of the first elastic member 12, remains in the first posture and moves on the movable groove 21 of the travel disk 2.

[0053] like Figure 5 、 Figure 6 and Figure 7 As shown, when the opening angle of the left massage mechanism 100 and the right massage mechanism 200 is greater than the set angle, the knob 11 slides from the movable groove 21 to the positioning groove 22 in the first posture. When the knob 11 abuts against the blocking protrusion 23, the forward rotation of the clutch shaft 1 is not restricted by the first elastic member 12, so the blocking protrusion 23 can directly push the knob 11, so that the knob 11 can drive the entire clutch shaft 1 to rotate forward and transform to the second posture. Figure 5 and Figure 6 As shown, at this time, the turn button 11 can cross the blocking protrusion 23 in the second posture and slide into the positioning groove 22; then, under the action of the first elastic member 12, as shown in FIG. Figure 7 As shown, the clutch shaft 1, after rotating forward, automatically rotates in the reverse direction, driving the knob 11 to rotate back to the first position. At this point, the knob 11 in the first position, under the force of the first elastic member 12, remains against the blocking protrusion 23, securing the knob 11 within the positioning groove 22. This process automatically locks the opening angles of the left and right massage mechanisms 100 and 200.

[0054] When unlocking, refer to Figure 7 、 Figure 6 and Figure 5 , it is necessary to manually operate the clutch shaft 1 to rotate forward so that the knob 11 changes from the first posture to the second posture, allowing the knob 11 to cross the blocking protrusion 23 and slide back into the movable groove 21, thereby manually unlocking the left massage movement 100 and the right massage movement 200.

[0055] It can be seen that compared with the prior art, the massager provided in the embodiment of the present application improves the V-shaped massage movement structure in the massager, and an elastic mechanism and a clutch assembly are provided between the left massage movement 100 and the right massage movement 200 of the massager. The elastic mechanism is used to enable the left massage movement 100 and the right massage movement 200 to be folded or reset to each other in a hinge shape, so that the massager can maintain contact with the human body during normal use, effectively ensuring the massage strength and massage effect.

[0056] The clutch assembly acts as an opening angle lock for the left and right massage movements 100, 200, and is used to lock or unlock the opening angle between the left and right massage movements 100, 200. When the left and right massage movements 100, 200 of the massager are opened to a set angle, the clutch assembly automatically locks the opening angle, allowing the massager to be used at the locked opening angle. The clutch assembly can then be used to unlock the locked opening angles of the left and right massage movements 100, 200, allowing the massager to return to normal use. This expands the use scenarios of this type of massager and improves its performance.

[0057] For the specific structure of the above-mentioned turn button 11, please refer to Figure 6 、 Figure 7 and Figure 8 The turn button 11 can be preferably integrally formed on the clutch shaft 1, which is beneficial to improving the structural strength and synchronization with the clutch shaft 1. When the clutch shaft 1 rotates, the turn button 11 can be driven to rotate synchronously; conversely, when the turn button 11 is pushed up, the entire clutch shaft 1 can also be driven to rotate by the turn button 11, thereby improving synchronization.

[0058] The turn button 11 has a cutout 111, which is used to clear the blocking protrusion 23. Specifically, the cutout 111 can be provided on the clutch shaft 1 corresponding to the position of the travel plate 2, so that the portion with the cutout 111 serves as the turn button 11 on the clutch shaft 1. The depth of the cutout 111 can be adjusted based on the height of the blocking protrusion 23 to ensure that the turn button 11 can use the cutout 111 to cross the blocking protrusion 23 and switch between the movable groove 21 and the positioning groove 22. In this embodiment, the cutout 111 is preferably semicircular, giving the turn button 11 on the clutch shaft 1 a semicircular cylindrical structure.

[0059] In this embodiment, if Figure 7 As shown, the first posture of the knob 11 can preferably be the posture in which the semicircular cylinder stands upright on the travel disc 2; Figure 5 and Figure 6As shown, the second posture of the turn button 11 can preferably be the posture of the semicircular cylinder after rotating 90 degrees. In this posture, the cutout 111 can avoid the blocking protrusion 23, so that the entire turn button 11 can cross over the blocking protrusion 23.

[0060] In another embodiment of the present application (not shown), a plurality of positioning grooves 22 may be provided on the travel disc 2 , and adjacent positioning grooves 22 may have movable grooves 21 separated by blocking protrusions 23 .

[0061] In this way, the knob 11 can be selectively buckled into different positioning slots 22 to achieve switching between different gears, thereby increasing the opening positioning angle between the left massage movement 100 and the right massage movement 200, effectively expanding the use scenarios of the massager.

[0062] In the massager of the embodiment of the present application, there is a connecting mechanism between the left massage movement 100 and the right massage movement 200. Figure 8 and Figure 9 The connecting end of the left massage movement 100 is provided with a cylinder 101 located in the middle and protruding, and a first shell 102 arranged on both sides of the cylinder 101; correspondingly, the connecting end of the right massage movement 200 is provided with a groove 201 for the cylinder 101 to be embedded, and there are also second shells 202 on both sides of the groove 201, and the second shell 202 can be mutually connected with the first shell 102 on the left massage movement 100.

[0063] In this way, the left massage movement 100 and the right massage movement 200 can be interlocked in a "concave-convex" shape and connected and combined into one. The connection between the left massage movement 100 and the right massage movement 200 can rotate relative to each other, so that the left massage movement 100 and the right massage movement 200 can be folded or opened.

[0064] Regarding the installation structure of the clutch assembly on the massager, in one embodiment of the present application, please refer to Figure 8 and Figure 9 The right massage movement 200 has a travel disc 2 on both sides of the connection end. In conjunction, the left massage movement 100 has a connection seat 3 for mounting the clutch shaft 1 on the connection end. The connection seat 3 supports the clutch shaft 1 on the travel disc 2 so that the knob 11 on the clutch shaft 1 can fit on the travel disc 2.

[0065] In this embodiment, two connecting seats 3 are provided on the connecting end of the left massage mechanism 100. Both connecting seats 3 have through holes for receiving the clutch shaft 1. The clutch shaft 1 is mounted on the two connecting seats 3, with the two ends of the clutch shaft 1 extending from the outer sides of the two connecting seats 3. The protruding portions of the clutch shaft 1 are located just above the travel disc 2. The knob 11 is provided on the end of the clutch shaft 1 extending from the connecting seat 3 and can be attached to the travel disc 2.

[0066] In this way, the clutch shaft 1 can be supported by the connecting base 3, so that the knob 11 on the clutch shaft 1 can correspond to the position of the travel disk 2, so that the knob 11 can fit on the travel disk 2 and cooperate with the contour of the travel disk 2 to achieve the corresponding unlocking or locking operation. The clutch assembly of the present application is only installed on the connection mechanism between the left massage movement 100 and the right massage movement 200 of the massager. The entire clutch assembly is not interfered with by other structural parts of the massager. Therefore, the clutch assembly is not restricted by the shape of the massager, which helps to improve the installation flexibility of the clutch assembly.

[0067] Preferably, if Figure 8 As shown, at least one end of the clutch shaft 1 further extends outward, and an operating portion 13 is provided on the extended end of the clutch shaft 1. The operating portion 13 is used for manual operation to drive the clutch shaft 1 to rotate to achieve unlocking operation, which is convenient and easy to use.

[0068] In this embodiment, the operating portion 13 is a rotary cap or a rotary disk on the end of the clutch shaft 1. A person can manually operate the rotary cap or the rotary disk to drive the entire clutch shaft 1 to rotate. In other embodiments, the operating portion 13 can also be a handle or a hand crank on the end of the clutch shaft 1, as long as it can drive the clutch shaft 1 to rotate. This is not specifically limited here.

[0069] It should be noted that the setting positions of the above-mentioned connecting seat 3 and the travel disk 2 can also be interchanged with each other, that is, the connecting seat 3 can also be set on the right massage movement 200, and the travel disk 2 can also be set on the left massage movement 100, and the same technical effect can be achieved.

[0070] Regarding the structure on the connecting seat 3 that cooperates with the clutch shaft 1, in one embodiment of the present application, please refer to Figure 8 and Figure 9 A fixing buckle 31 is provided on the connecting seat 3, and the first elastic member 12 can preferably be a torsion spring. The first elastic member 12 is wound and fixed on the clutch shaft 1, and the extending end of the first elastic member 12 is fixed on the fixing buckle 31 of the connecting seat 3.

[0071] As can be seen, the first elastic member 12 has a simple mounting structure and is easy to disassemble and replace. The force of the first elastic member 12 enables the knob 11 to maintain a position against the blocking protrusion 23 under normal conditions, effectively ensuring the locking effect of the opening angle of the left massage movement 100 and the right massage movement 200.

[0072] In another embodiment of this application, please refer to Figure 8 and Figure 9 The clutch shaft 1 is further provided with a limit block 14, and the connecting seat 3 is provided with a stopper protrusion 32 that cooperates with the limit block 14. The limit block 14 on the clutch shaft 1 and the stopper protrusion 32 on the connecting seat 3 cooperate to limit the rotation angle of the clutch shaft 1, thereby limiting the rotation range of the clutch shaft 1, effectively improving the posture change accuracy of the rotary buckle 11, and further improving the stability of the clutch assembly's unlocking or self-locking operation.

[0073] In this embodiment, the notch 111 on the turn button 11 is semicircular, so that the overall shape of the turn button 11 is a semicircular cylindrical portion on the clutch shaft 1. The first posture of the turn button 11 is the posture of the semicircular cylinder standing upright on the travel plate 2. Therefore, when the turn button 11 rotates 90 degrees, the notch 111 on the turn button 11 can clear the blocking protrusion 23. In other words, after the semicircular cylinder rotates 90 degrees, the notch 111 is located downward and can clear the blocking protrusion 23. Therefore, the rotation range of the clutch shaft 1 can be preferably set within the range within which the clutch shaft 1 can rotate 90 degrees.

[0074] Regarding the structure of the travel disc 2, in one embodiment of the present application, please refer to Figure 8 and Figure 9 , the travel disc 2 is preferably a symmetrical part, which is conducive to improving the versatility of accessories and reducing production costs. In the present embodiment, the two travel discs 2 of the symmetrical part are respectively arranged on both sides of the right massage movement 200 connection end.

[0075] Among them, such as Figure 9 As shown, the travel disc 2 is a fan-shaped disc body, and an insertion shaft 24 is provided on the travel disc 2. In this embodiment, the insertion shaft 24 is preferably arranged in the middle of the travel disc 2, and the shape on the travel disc 2 is symmetrically arranged about its axis.

[0076] The travel disc 2 is vertically arranged and fixed to the side of the connecting end of the right massage movement 200 by the insertion shaft 24. The fan-shaped edge of the travel disc 2 has the positioning groove 22 and the movable groove 21, as well as a blocking protrusion 23 between the positioning groove 22 and the movable groove 21.

[0077] In this way, the clutch shaft 1 is supported by the connecting seat 3, and the knob 11 on the clutch shaft 1 is located above the travel disc 2. The positioning groove 22 and the movable groove 21 provided on the fan-shaped edge of the travel disc 2 can closely cooperate with the knob 11 to achieve unlocking or self-locking operation.

[0078] In this embodiment, if Figure 5 、 Figure 6 and Figure 7 As shown, the positioning groove 22 is set on the mid-vertical line of the travel plate 2, the blocking protrusions 23 are located on both sides of the positioning groove 22, and the movable grooves 21 extend from the blocking protrusions 23 on both sides to both sides of the fan-shaped edge of the travel plate 2.

[0079] In this way, a self-locking operation can be achieved when the opening angle of the left massage movement 100 and the right massage movement 200 is close to 180 degrees.

[0080] In other embodiments, the positioning slot 22 can be widened to achieve earlier locking of the knob 11. For example, the knob 11 can be automatically locked when the left massage mechanism 100 and the right massage mechanism 200 are opened to an angle of 170 degrees. This can be adjusted based on the massager's configuration requirements, thereby expanding the massager's usage scenarios.

[0081] For the structure of the elastic mechanism, in one embodiment of the present application, please refer to Figure 9 The elastic mechanism is preferably a second elastic member 4 sleeved on the insertion shaft 24, and the second elastic member 4 can also preferably be a torsion spring.

[0082] In this embodiment, the insertion shaft 24 of the travel disc 2 can be sequentially passed through the second elastic member 4 and then inserted into the side hole of the second housing 202. The second elastic member 4 is wound around the insertion shaft 24, one end of the second elastic member 4 is fixed to the left massage movement 100, and the other end of the second elastic member 4 is fixed to the right massage movement 200.

[0083] In this way, the connection structure between the elastic mechanism and the left massage movement 100 and the right massage movement 200 is compactly matched, which is conducive to saving internal space and can effectively provide a folding force for the left massage movement 100 and the right massage movement 200, so that when the massager is in use, the left massage movement 100 and the right massage movement 200 can automatically lean against the human body, effectively ensuring the massage strength and massage effect of the massage head.

[0084] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
