Description

Technical Field

[0001] This application belongs to the field of massage technology, specifically relating to massage mechanisms and massage devices. Background Technology

[0002] The massager in the related technology includes a ratchet-type adjustment assembly consisting of a first adjustment element and a second adjustment element. The second adjustment element is driven by a rotating shaft to rotate relative to the first adjustment element, thereby adjusting the distance between the two massage components. Currently, the first adjustment element also has a ratchet engagement with the housing circumferentially, but the ratchet engagement direction is opposite to that of the second adjustment element. When the rotating shaft rotates, it can drive the second adjustment element to rotate relative to the first adjustment element, and the first adjustment element is locked to the housing. When the rotating shaft rotates in the opposite direction, it drives the second adjustment element and the first adjustment element to rotate relative to the housing, but this results in a relatively high level of noise. Summary of the Invention

[0003] In view of this, the first aspect of this application provides a massage mechanism, including a housing, a rotating shaft, an adjustment assembly, and two massage components. The adjustment assembly includes a first adjustment element and a second adjustment element that unidirectionally cooperates with the first adjustment element in the circumferential direction. The first adjustment element is fixed to the housing, and the second adjustment element and the two massage components are sleeved on the rotating shaft. The rotating shaft is connected to the two massage components in a transmission manner.

[0004] When the rotating shaft rotates in the first direction, the second adjusting member rotates relative to the first adjusting member, thereby moving the second adjusting member along the axial direction of the rotating shaft, and thus adjusting the distance between the two massage components.

[0005] When the shaft rotates in the second direction, the second adjusting member is stationary relative to the shaft in the axial direction of the shaft, and the shaft rotates relative to the second adjusting member. The second direction is opposite to the first direction.

[0006] The adjusting assembly further includes a one-way bearing, which is sleeved on the rotating shaft, and the second adjusting component is sleeved on the one-way bearing;

[0007] When the rotating shaft rotates along the first direction, it drives the one-way bearing and the second adjusting member to rotate; when the rotating shaft rotates along the second direction, the rotating shaft rotates relative to the second adjusting member through the one-way bearing.

[0008] The adjustable distance assembly further includes a bearing sleeve, which is fitted onto the rotating shaft and circumferentially limited to the rotating shaft. The one-way bearing is fitted onto and connected to the bearing sleeve. When the rotating shaft rotates, it drives the bearing sleeve and the one-way bearing to rotate.

[0009] The second adjusting member is provided with a receiving groove, the opening direction of the receiving groove is opposite to that of the first adjusting member, and the one-way bearing is located in the receiving groove.

[0010] The rotating shaft passes through the one-way bearing and the second adjusting member. The one-way bearing, the second adjusting member, and the massage component are movable relative to the rotating shaft. The massage component abuts against the side of the second adjusting member and / or the one-way bearing away from the first adjusting member.

[0011] When the second adjusting member moves away from the first adjusting member, the second adjusting member drives the one-way bearing and the massage assembly to move away from the first adjusting member.

[0012] The distance adjustment component further includes an elastic element and a fixing element. The fixing element is located on the side of the massage component away from the first distance adjustment component and is fixed to the housing. The opposite ends of the elastic element are respectively connected to the massage component and the fixing element.

[0013] When the massage component and the second adjusting member move away from the first adjusting member, the elastic member is in a compressed state; when the second adjusting member rotates relative to the first adjusting member to a preset position, the compressed elastic member can drive the massage component and the second adjusting member to move towards the first adjusting member.

[0014] The rotating shaft includes two separate rotating shaft parts, each of the massage components is sleeved on one of the rotating shaft parts, and the axial direction is limited to the rotating shaft part, and the one-way bearing is sleeved on the rotating shaft part;

[0015] When the second adjusting member moves away from the first adjusting member, the second adjusting member causes the one-way bearing and the rotating shaft to move away from the first adjusting member, thereby causing the massage assembly to move away from the first adjusting member.

[0016] The adjustable distance assembly further includes an elastic element and a fixing element. The fixing element is disposed on the side of the massage assembly or the rotating shaft that is away from the first adjustable distance assembly, and the fixing element is fixed to the housing. The opposite ends of the elastic element are respectively connected to the fixing element and the massage assembly or the rotating shaft.

[0017] When the massage component, the second adjusting member, and the rotating shaft move away from the first adjusting member, the elastic member is in a compressed state; when the second adjusting member rotates relative to the first adjusting member to a preset position, the elastic member in the compressed state can drive the massage component, the second adjusting member, and the rotating shaft to move in a direction closer to the first adjusting member.

[0018] The second adjusting member is provided with a receiving groove, the opening of which faces the first adjusting member, and the one-way bearing is disposed in the receiving groove; the rotating shaft includes two separate rotating shaft parts, each of the massage components is sleeved on one of the rotating shaft parts, the one-way bearing is sleeved on the rotating shaft part, and the axial directions of the massage components, the one-way bearing and the second adjusting member are all limited to the rotating shaft part;

[0019] When the second adjusting member moves away from the first adjusting member, it causes the rotating shaft to move away from the first adjusting member as well. The rotating shaft then causes the one-way bearing and the massage assembly to move away from the first adjusting member.

[0020] The adjusting component further includes a limiting member, which includes a connecting part and an abutting part protruding from the peripheral side of the connecting part. The connecting part is disposed inside the one-way bearing and connected to the rotating shaft part, and the abutting part abuts against the end side of the one-way bearing.

[0021] When the rotating shaft moves away from the first adjusting member, it drives the limiting member to move away from the first adjusting member as well, and then drives the one-way bearing to move away from the first adjusting member through the abutting part.

[0022] The adjustable distance assembly further includes an elastic element, which is disposed on the side of the massage assembly or the rotating shaft that is away from the first adjustable distance assembly. One end of the elastic element is connected to the inner sidewall of the housing, and the other end is connected to the massage assembly or the rotating shaft.

[0023] When the massage component, the second adjusting member, and the rotating shaft move away from the first adjusting member, the elastic member is in a compressed state; when the second adjusting member rotates relative to the first adjusting member to a preset position, the elastic member in the compressed state can drive the massage component, the second adjusting member, and the rotating shaft to move in a direction closer to the first adjusting member.

[0024] The massage mechanism includes two adjustment components, which are located on the outer or inner sides of the two massage components. Each adjustment component is used to control the movement of one of the massage components.

[0025] When the two adjustment components are located inside the two massage components, the two first adjustment elements in the two adjustment components are arranged opposite to each other and connected to each other.

[0026] The housing includes a first sub-housing and a second sub-housing, which together form a receiving space. The rotating shaft and the adjusting component are disposed within the receiving space. A portion of the massage component protrudes from the first sub-housing. At least one of the first sub-housing and the second sub-housing is limited to the periphery of the first adjusting component by a limiting protrusion and a limiting groove.

[0027] Wherein, at least a portion of the groove wall of the limiting groove and at least a portion of the peripheral side surface of the limiting protrusion are planar.

[0028] The second aspect of this application provides a massage device, which includes a massage mechanism as provided in the first aspect of this application.

[0029] The massage mechanism and massager provided in this application involve fixing a first adjusting member to the housing and a second adjusting member sleeved on a rotating shaft. When the rotating shaft rotates in a first direction, it drives the second adjusting member to rotate synchronously, causing the second adjusting member to rotate relative to the first adjusting member. This allows the second adjusting member to move along the axial direction of the rotating shaft, thereby adjusting the distance between the two massage components and achieving the function of adjusting the distance. However, at this time, the first adjusting member remains fixed because it is fixed to the housing. When the rotating shaft rotates in the opposite second direction, it no longer drives the second adjusting member to rotate. The second adjusting member remains stationary relative to the rotating shaft in the axial direction, meaning that both the second and first adjusting members remain fixed, and only the rotating shaft rotates relative to the second adjusting member.

[0030] In summary, compared to related technologies, the first adjusting member generates significant noise during rotation relative to the housing, and both the first adjusting member and the housing are prone to wear, reducing their service life. This application adjusts the relative rotation to the position between the rotating shaft and the second adjusting member. The relative rotation between the rotating shaft and the second adjusting member reduces noise, and the rotating shaft and the second adjusting member are less prone to wear, thus increasing their service life.

Detailed Implementation

[0058] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0059] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0060] With the ever-evolving fast pace and high-pressure environment of modern life, people's work and lifestyles have undergone profound changes. Prolonged sitting at a desk or focusing on electronic screens has become the norm for many. Maintaining the same posture for extended periods, coupled with a lack of necessary physical activity, leads to the gradual accumulation of muscle tension and stiffness in key weight-bearing and frequently moving areas such as the neck and shoulders. This hinders blood circulation and exacerbates problems like insufficient local nutrient supply and the accumulation of metabolic waste. Over time, this can gradually evolve into more serious health problems, such as the chronic pain of frozen shoulder and the degenerative changes in the cervical spine caused by cervical spondylosis, severely impacting people's quality of life.

[0061] As a convenient health aid, massage devices can effectively relieve muscle tension, promote blood circulation, and accelerate the excretion of metabolic waste by simulating manual massage techniques such as kneading, tapping, and vibration, thereby helping users restore physical vitality and reduce fatigue.

[0062] However, despite the significant advantages of massage devices in relieving physical fatigue, current products on the market still have certain design shortcomings. Specifically, most massage devices are relatively simple in their massage methods, mainly relying on rotational or oscillating mechanical movements, ignoring the differences in the body structure of different users. In particular, the width and curve of the neck and shoulders vary from user to user, making it difficult for the massage device to accurately conform to the user's body contours during actual use. This affects the accuracy and comfort of the massage, and may even cause new discomfort due to improper massage intensity and position.

[0063] To address the aforementioned problems, researchers have provided a massager that utilizes a ratchet-type adjustment assembly to achieve spacing adjustment. Specifically, the adjustment assembly includes a first adjustment element and a second adjustment element. The first adjustment element engages with the housing via a ratchet in one direction, while the second adjustment element engages with the first adjustment element via a ratchet in the opposite direction. A rotating shaft is fixedly connected to the second adjustment element. Therefore, when the rotating shaft rotates in the first direction, it drives the second adjustment element to rotate synchronously, causing the second adjustment element to rotate relative to the first adjustment element via a ratchet engagement. At this time, the ratchet engagement direction of the first adjustment element and the housing is opposite, thus locking the first adjustment element to the housing and keeping it fixed. When the shaft rotates in the opposite second direction, it drives the second adjustment element to rotate synchronously in the opposite direction. At this time, the second adjustment element and the first adjustment element are locked together, and the second adjustment element can drive the first adjustment element to rotate synchronously in the opposite direction, causing the first adjustment element to rotate relative to the housing via a ratchet engagement.

[0064] As can be seen from the above process, when the shaft rotates in the first direction, the first and second adjusting components cooperate to adjust the distance, and the second adjusting component locks itself into place with the housing. However, when the shaft rotates in the opposite direction, the first and second adjusting components lock themselves into place, and the second adjusting component rotates relative to the housing. Because the contact area between the second adjusting component and the housing is relatively large, and it is in a massaging state during reverse rotation, this state lasts for a long time, resulting in not only high noise levels but also a prolonged duration. Furthermore, the prolonged contact between the second adjusting component and the housing easily causes wear and tear on the component, reducing its service life.

[0065] In view of this, and in order to solve the above problems, this application provides a massage mechanism and a massage device. Please refer to them together. Figures 1-5 , Figure 1 This is a three-dimensional structural diagram of the massage mechanism in one embodiment of this application. Figure 2 for Figure 1 The exploded view of the massage mechanism shown. Figure 3 for Figure 1 The diagram shows a cross-sectional view of the massage mechanism. Figure 4 This is a three-dimensional structural diagram of the rotating shaft, the adjustable distance assembly, and the two massage assemblies in one embodiment of this application. Figure 5 for Figure 4The diagram shows an exploded view of the rotating shaft, the adjusting assembly, and the two massage components. The massage mechanism 1 provided in this embodiment includes a housing 10, a rotating shaft 20, an adjusting assembly 30, and two massage components 40. The adjusting assembly 30 includes a first adjusting member 31 and a second adjusting member 32 that unidirectionally engages with the first adjusting member 31 in the circumferential direction. The first adjusting member 31 is fixed to the housing 10. The second adjusting member 32 and the two massage components 40 are sleeved on the rotating shaft 20, and the rotating shaft 20 is drively connected to the two massage components 40. When the rotating shaft 20 rotates in a first direction, the second adjusting member 32 rotates relative to the first adjusting member 31, thereby moving the second adjusting member 32 along the axial direction of the rotating shaft 20, thus adjusting the distance between the two massage components 40. When the rotating shaft 20 rotates in a second direction, the second adjusting member 32 is stationary relative to the rotating shaft 20 in the axial direction, and the rotating shaft 20 rotates relative to the second adjusting member 32. The second direction is opposite to the first direction.

[0066] The housing 10, serving as the outer shell, primarily houses and protects the various components of the massage mechanism 1. The rotating shaft 20 and adjusting components can be housed within the housing 10. The transmission portion of the massage assembly 40 is located within the housing 10, while the massage portion is located outside the housing 10 to facilitate massage for the user. The rotating shaft 20 can rotate along its own axis, and its rotation can be electrically controlled by a motor or other components, or manually controlled by the user. In other words, the massage mechanism 1 may also include a drive component 50, which can be either electric or manual. Regardless of whether it is electrically or manually controlled, the rotating shaft 20 can rotate in a first direction or a second direction, with the first direction being opposite to the second direction. For example, the rotating shaft 20 can rotate clockwise or counterclockwise.

[0067] Two massage components 40 are mounted on the rotating shaft 20 and spaced apart. When the rotating shaft 20 rotates, it drives the massage components 40 to move, thereby achieving massage. Furthermore, when the rotating shaft 20 rotates in a first direction, the massage components 40 can move in a third direction; when the rotating shaft 20 rotates in a second direction, the massage components 40 can move in the opposite fourth direction. In other words, the rotating shaft 20 can drive the massage components 40 to perform massage regardless of which direction it rotates, but the distance between the two massage components 40 cannot be adjusted at this time.

[0068] The pitch adjustment assembly 30 primarily achieves the pitch adjustment function through the interaction of a first pitch adjustment member 31 and a second pitch adjustment member 32. The first pitch adjustment member 31 can be fixed to the housing 10, meaning that the first pitch adjustment member 31 will not move relative to the housing 10, and the first pitch adjustment member 31 and the housing 10 remain fixed. The first pitch adjustment member 31 and the second pitch adjustment member 32 engage in a unidirectional ratchet engagement in the circumferential direction. The second pitch adjustment member 32 is sleeved on the rotating shaft 20, and the rotation of the rotating shaft 20 can drive the second pitch adjustment member 32 to rotate. In other words, when the rotating shaft 20 rotates in one direction, the rotating shaft 20 can drive the second pitch adjustment member 32 to rotate relative to the first pitch adjustment member 31, but when the rotating shaft 20 rotates in the opposite direction, the rotating shaft 20 cannot drive the second pitch adjustment member 32 to rotate relative to the first pitch adjustment member 31, and the second pitch adjustment member 32 and the first pitch adjustment member 31 are locked together. Optionally, the first pitch adjustment member 31 and the second pitch adjustment member 32 are ratchet-type components, so that they can only rotate relative to each other in one direction, and are locked together in the opposite direction.

[0069] With the above configuration, this embodiment allows the second adjusting member 32 to rotate synchronously when the rotating shaft 20 rotates in the first direction, causing the second adjusting member 32 to rotate relative to the first adjusting member 31, thereby moving the second adjusting member 32 along the axial direction of the rotating shaft 20. The second adjusting member 32 can be directly or indirectly connected to the massage assembly 40, so when the second adjusting member 32 moves, it can drive the massage assembly 40 to move, thereby adjusting the distance between the two massage assemblies 40 and achieving the function of adjusting the distance. However, at this time, the first adjusting member 31 remains fixed because it is fixed to the housing 10. When the rotating shaft 20 rotates in the opposite second direction, since the first adjusting member 31 is fixedly connected to the housing 10 and the second adjusting member 32 is locked to the first adjusting member 31, the rotating shaft 20 will no longer drive the second adjusting member 32 to rotate. The second adjusting member 32 is stationary relative to the rotating shaft 20 in the axial direction of the rotating shaft 20. That is, both the second adjusting member 32 and the first adjusting member 31 remain fixed. However, at this time, the rotating shaft 20 can rotate relative to the second adjusting member 32, thereby avoiding motion interference.

[0070] In summary, compared to related technologies, the first adjusting member 31 generates significant noise when rotating relative to the housing 10, and both the first adjusting member 31 and the housing 10 are prone to wear, reducing their service life. This embodiment adjusts the relative rotation to the position between the rotating shaft 20 and the second adjusting member 32. The relative rotation between the rotating shaft 20 and the second adjusting member 32 reduces noise, and the rotating shaft 20 and the second adjusting member 32 are less prone to wear, thus increasing their service life.

[0071] In this embodiment, the massage mechanism 1 may include one or two adjusting components 30. When the massage mechanism 1 includes one adjusting component 30, the adjusting component 30 may be set in any one of the two massage components 40. The adjusting component 30 can control one massage component 40 to move axially, while the axial direction of the other massage component 40 remains fixed, thereby realizing the adjustment of the distance between the two massage components 40.

[0072] When the massage mechanism 1 includes two adjusting components 30, one adjusting component 30 controls one massage component 40 to move axially, and the other adjusting component 30 controls the other massage component 40 to move axially. In other words, both massage components 40 can move axially, thereby better adjusting the distance between the two massage components 40. This embodiment is only illustrated by the massage mechanism 1 including two adjusting components 30. For details, please refer to [the relevant documentation]. Figures 4-9 , Figure 6 This is a three-dimensional structural diagram of the massage mechanism in another embodiment of this application. Figure 7 for Figure 6 The exploded view of the massage mechanism shown. Figure 8 This is a three-dimensional structural diagram of the rotating shaft, the adjustable distance assembly, and the two massage assemblies in another embodiment of this application. Figure 9 for Figure 8 The diagram shows an exploded view of the rotating shaft, the adjusting assembly, and the two massage components. In this embodiment, the massage mechanism 1 includes two adjusting assemblies 30, which are located on the outer or inner sides of the two massage components 40. Each adjusting assembly 30 is used to control the movement of one of the massage components 40.

[0073] Two massage components 40 can be simultaneously positioned on the outer or inner sides of the two massage components 40, thereby achieving overall structural symmetry and simplifying the structure of the massage mechanism 1. Two adjustable distance components 30 can each control one massage component 40, providing more flexible control. For example... Figure 4 As shown, when the two massage components 40 are located on the outside of the two massage components 40, it does not affect the existing structure and is easy to install. Figure 8 As shown, when the two massage components 40 are located inside the two massage components 40, the internal space of the massage mechanism 1 can be used for installation without adding extra space, thus achieving miniaturization of the massage mechanism 1.

[0074] Please refer to this again. Figures 8-9 In this embodiment, when the two adjustment components 30 are disposed inside the two massage components 40, the two first adjustment members 31 in the two adjustment components 30 are disposed opposite to each other and connected to each other.

[0075] When the two adjusting components 30 are located inside the two massage components 40, the two adjusting components 30 are close to each other, and the two first adjusting elements 31 in the two adjusting components 30 are close to each other and arranged opposite to each other. This embodiment allows the two first adjusting elements 31 to be connected to each other, that is, there is no need to set two structural components. The two first adjusting elements 31 are integrated together and only one structural component is required, which can further simplify the mechanism of the massage core 1 and realize the miniaturization of the massage core 1.

[0076] Optionally, the two first adjusting elements 31 in the two adjusting components 30 can be either an integral structure or a separate structure.

[0077] Please refer to this as well. Figure 2 , Figure 7 ,as well as Figure 10 , Figure 10 This is an exploded view of the second sub-shell and the first adjusting member in one embodiment of this application. In this embodiment, the shell 10 includes a first sub-shell 11 and a second sub-shell 12, which enclose a receiving space. The rotating shaft 20 and the adjusting component 30 are disposed within the receiving space. A portion of the massage component 40 protrudes from the first sub-shell 11. At least one of the first sub-shell 11 and the second sub-shell 12 is limited and engaged with the periphery of the first adjusting member 31 by a limiting protrusion 310 and a limiting groove 120.

[0078] The housing 10 can be composed of two sub-housings: a first sub-housing 11 and a second sub-housing 12. The first sub-housing 11 and the second sub-housing 12 can enclose a receiving space. Various components can be installed in the first sub-housing 11 first, such as the rotating shaft 20 and the adjusting assembly 30, the transmission part of the massage assembly 40, and the massage part protruding from the first sub-housing 11. After installation, the second sub-housing 12 is installed, thereby forming a receiving space and sealing the opening. When the adjusting assembly 30 is located in the receiving space, the peripheral side of the first adjusting member 31 in the adjusting assembly 30 can be limited and engaged with at least one of the first sub-housing 11 and the second sub-housing 12 and the peripheral side of the first adjusting member 31 through a limiting protrusion 310 and a limiting groove 120, thereby fixing the first adjusting member 31 to the housing 10 and ensuring that the first adjusting member 31 will not move relative to the housing 10. Optionally, the peripheral side of the first adjusting member 31 and the peripheral side of the first sub-housing 11 can be limited and engaged by the limiting protrusion 310 and the limiting groove 120, or the peripheral side of the first adjusting member 31 and the peripheral side of the second sub-housing 12 can be limited and engaged by the limiting protrusion 310 and the limiting groove 120.

[0079] In this embodiment, at least a portion of the groove wall of the limiting groove 120 and at least a portion of the peripheral side surface of the limiting protrusion 310 are planar. By designing the groove wall of the limiting groove 120 and the peripheral side surface of the limiting protrusion 310 as planar rather than curved surfaces, the first adjusting member 31 can be further prevented from rotating circumferentially relative to the housing 10, thus improving the limiting effect of the first adjusting member 31. Optionally, at the corners of the housing 10, the groove wall of the limiting groove 120 and the peripheral side surface of the limiting protrusion 310 can be designed as curved surfaces to improve the appearance. The remaining parts can be designed as planar to improve the limiting effect.

[0080] Please refer to this as well. Figures 11-13 , Figure 11 This is a three-dimensional structural diagram of the rotating shaft, the pitch adjustment assembly, the one-way bearing, and the bearing sleeve in one embodiment of this application. Figure 12 for Figure 11 The exploded view shows the rotating shaft, the pitch adjustment assembly, the one-way bearing, and the bearing sleeve. Figure 13 for Figure 11 The diagram shows a side view of the rotating shaft, adjusting assembly, one-way bearing, and bearing sleeve. In this embodiment, the adjusting assembly 30 further includes a one-way bearing 33, which is sleeved on the rotating shaft 20, and the second adjusting member 32 is sleeved on the one-way bearing 33. When the rotating shaft 20 rotates along the first direction, it drives the one-way bearing 33 and the second adjusting member 32 to rotate; when the rotating shaft 20 rotates along the second direction, the rotating shaft 20 rotates relative to the second adjusting member 32 via the one-way bearing 33.

[0081] A one-way bearing 33 is a type of bearing that can rotate freely in one direction and lock in the other; it is also called an overrunning clutch. In this embodiment, the one-way bearing 33 is first fitted onto the rotating shaft 20, and then the second adjusting member 32 is fitted onto the one-way bearing 33. Thus, when the rotating shaft 20 rotates in the first direction, the one-way bearing 33 locks, allowing the rotating shaft 20 to drive both the one-way bearing 33 and the second adjusting member 32 to rotate together, thereby achieving the function of adjusting the distance. When the rotating shaft 20 rotates in the opposite second direction, the one-way bearing 33 can rotate freely, allowing the rotating shaft 20 to rotate relative to the second adjusting member 32 via the one-way bearing 33. This achieves mutual locking between the second adjusting member 32 and the first adjusting member 31, preventing changes in the distance between the two massage components 40, ensuring the stability of the distance between the two massage components 40, and improving the stability of the massage process.

[0082] In summary, the engagement and disengagement process between the rotating shaft 20 and the second adjusting member 32 can be achieved through the one-way bearing 33. This allows the second adjusting member 32 to rotate synchronously only when the rotating shaft 20 rotates in the first direction, but to engage and disengage with the rotating shaft 20 in the second direction, thus achieving different controls in the two directions. The one-way bearing 33 has a simple structure, which is beneficial for making reasonable use of the internal space of the massage mechanism 1 and achieving miniaturization of the massage mechanism 1.

[0083] In this embodiment, the adjusting assembly 30 further includes a bearing sleeve 34, which is sleeved on the rotating shaft 20 and circumferentially limited to the rotating shaft 20. The one-way bearing 33 is sleeved on and connected to the bearing sleeve 34. When the rotating shaft 20 rotates, it drives the bearing sleeve 34 and the one-way bearing 33 to rotate.

[0084] Based on the one-way bearing 33, the pitch adjustment assembly 30 can also be equipped with a bearing sleeve 34. The bearing sleeve 34 can be fitted onto the outside of the rotating shaft 20 and is axially limited to the rotating shaft 20, that is, the bearing sleeve 34 and the rotating shaft 20 are fixed to each other in the circumferential direction. At the same time, the one-way bearing 33 can also be fitted onto and connected to the bearing sleeve 34, that is, the bearing sleeve 34 can also fix the one-way bearing 33. In other words, in this embodiment, the rotating shaft 20 and the one-way bearing 33 are fixedly connected by the bearing sleeve 34. When the rotating shaft 20 rotates, it can drive the bearing sleeve 34 and the one-way bearing 33 to rotate. The bearing sleeve 34 can make the rotating shaft 20 and the one-way bearing 33 better cooperate, which can effectively prevent the one-way bearing 33 from shifting from the rotating shaft 20 when subjected to external force, thereby affecting the massage distance between the two massage components 40, and thus affecting the massage effect and user experience. In addition, the use of bearing sleeve 34 also helps to achieve the goal of miniaturization of massage mechanism 1. Bearing sleeve 34 allows for a more compact design of one-way bearing 33 and rotating shaft 20.

[0085] In this embodiment, the second adjusting member 32 is provided with a receiving groove 320, the opening direction of the receiving groove 320 is opposite to that of the first adjusting member 31, and the one-way bearing 33 is disposed in the receiving groove 320.

[0086] In this embodiment, a receiving groove 320 can be formed on the side of the second adjusting member 32 away from the first adjusting member 31. The one-way bearing 33 and even the bearing sleeve 34 can be disposed in the receiving groove 320, thereby making the structure of the massage mechanism 1 more compact and miniaturized. Secondly, the opening direction of the receiving groove 320 is set on the side of the second adjusting member 32 away from the first adjusting member 31. When the second adjusting member 32 moves axially away from the first adjusting member 31, it can drive the one-way bearing 33 to move together, so that the second adjusting member 32 and the one-way bearing 33 are always engaged and will not separate.

[0087] Please refer to Figure 14 , Figure 14 for Figure 4 The diagram shows a cross-sectional view of the rotating shaft, adjusting assembly, and two massage components. In this embodiment, the rotating shaft 20 passes through the one-way bearing 33 and the second adjusting member 32. The one-way bearing 33, the second adjusting member 32, and the massage component 40 are movable relative to the rotating shaft 20. The massage component 40 abuts against the side of the second adjusting member 32 and / or the one-way bearing 33 away from the first adjusting member 31. Specifically, when the second adjusting member 32 moves in a direction away from the first adjusting member 31, the second adjusting member 32 drives the one-way bearing 33 and the massage component 40 to move in the same direction away from the first adjusting member 31.

[0088] The rotating shaft 20 can completely pass through the one-way bearing 33 and the second adjusting member 32, allowing the one-way bearing 33, the second adjusting member 32, and the massage component 40 to move relative to the rotating shaft 20. That is, the one-way bearing 33, the second adjusting member 32, and the massage component 40 can all move axially relative to the rotating shaft 20, while the rotating shaft 20 remains fixed. Furthermore, the side of the second adjusting member 32 and / or the one-way bearing 33 facing away from the first adjusting member 31 can be used to abut against the massage component 40. Thus, when the second adjusting member 32 moves away from the first adjusting member 31, it drives the one-way bearing 33 and the massage component 40 to move away from the first adjusting member 31, thereby directly driving the massage component 40 to move away from the first adjusting member 31 as well, achieving the spacing adjustment function. By using the second adjusting member 32 to drive the one-way bearing 33 and the massage component 40 to move on the rotating shaft 20, the rotating shaft 20 remains fixed, simplifying the internal space.

[0089] Please refer to Figure 15 , Figure 15 for Figure 1 The diagram shows a three-dimensional structure of the massage mechanism after removing the second sub-shell. In this embodiment, the adjusting assembly 30 further includes an elastic element 35 and a fixing element 36. The fixing element 36 is located on the side of the massage assembly 40 away from the first adjusting element 31 and is fixed to the shell 10. The opposite ends of the elastic element 35 are respectively connected to the massage assembly 40 and the fixing element 36. When the massage assembly 40 and the second adjusting element 32 move away from the first adjusting element 31, the elastic element 35 is in a compressed state. When the second adjusting element 32 rotates relative to the first adjusting element 31 to a preset position, the compressed elastic element 35 can drive the massage assembly 40 and the second adjusting element 32 to move closer to the first adjusting element 31.

[0090] The fixing member 36 can be fixed to the side of the massage assembly 40 away from the first adjusting member 31 via the housing 10. One end of the elastic member 35 is connected to the fixing member 36, and the other end is connected to the massage assembly 40. Thus, when the massage assembly 40 and the second adjusting member 32 move away from the first adjusting member 31 in the aforementioned manner, the elastic member 35 can be in a compressed state. During the rotation of the second adjusting member 32, the second adjusting member 32 does not always move away from the first adjusting member 31. When the second adjusting member 32 rotates to a preset position, it can move closer to the first adjusting member 31. At this time, the compressed elastic member 35 can drive the massage assembly 40 and the second adjusting member 32 to move closer to the first adjusting member 31, thereby achieving the return of the massage assembly 40 and the second adjusting member 32 to their original positions.

[0091] In summary, this embodiment utilizes the cooperation between the second adjusting member 32 and the first adjusting member 31 to move the massage assembly 40 in a direction away from the first adjusting member 31. Furthermore, the rebound force of the elastic member 35 is used to reset the massage assembly 40.

[0092] Please refer to this as well. Figures 16-17 , Figure 16 This is a front view of the pivot, the adjustment assembly, and the two massage assemblies in another embodiment of this application. Figure 17 for Figure 16 The diagram shows a cross-sectional view of the rotating shaft, the adjusting assembly, and the two massage components. In this embodiment, the rotating shaft 20 includes two separate rotating shaft portions 21. Each massage component 40 is fitted onto one of the rotating shaft portions 21, and its axial direction is limited to the rotating shaft portion 21. The one-way bearing 33 is fitted onto the rotating shaft portion 21. When the second adjusting member 32 moves in a direction away from the first adjusting member 31, the second adjusting member 32 drives the one-way bearing 33 and the rotating shaft portion 21 to also move in a direction away from the first adjusting member 31, thereby driving the massage component 40 to also move in a direction away from the first adjusting member 31.

[0093] In another embodiment, the rotating shaft 20 can be split into two separate rotating shaft portions 21. One massage component 40 is fitted onto one rotating shaft portion 21, and the other massage component 40 is fitted onto the other rotating shaft portion 21. Simultaneously, the massage component 40 is axially limited within the rotating shaft portion 21; in other words, in this embodiment, the massage component 40 cannot move axially on the rotating shaft 20. Furthermore, the one-way bearing 33 can be fitted onto the rotating shaft portion 21. In this case, the rotating shaft portion 21 does not penetrate the second adjusting member 32. Thus, when the second adjusting member 32 moves in a direction away from the first adjusting member 31, the second adjusting member 32 can drive the one-way bearing 33 and the rotating shaft portion 21 as a whole to move in a direction away from the first adjusting member 31, thereby driving the massage component 40 to also move in a direction away from the first adjusting member 31, ultimately achieving the purpose of adjusting the massage spacing.

[0094] In summary, the second adjusting member 32 drives the rotating shaft 21 to move as a whole, thereby driving the massage component 40 to move. This eliminates the need for the second adjusting member 32 to come into contact with the massage component 40, and their positions can be set arbitrarily, which facilitates the position design of the massage component 40.

[0095] In this embodiment, the adjusting assembly 30 further includes an elastic element 35 and a fixing element 36. The fixing element 36 is disposed on the side of the massage assembly 40 or the rotating shaft 21 away from the first adjusting element 31, and the fixing element 36 is fixed to the housing 10. The opposite ends of the elastic element 35 are respectively connected to the fixing element 36 and the massage assembly 40 or the rotating shaft 21. When the massage assembly 40, the second adjusting element 32, and the rotating shaft 21 move in a direction away from the first adjusting element 31, the elastic element 35 is in a compressed state. When the second adjusting element 32 rotates relative to the first adjusting element 31 to a preset position, the compressed elastic element 35 can drive the massage assembly 40, the second adjusting element 32, and the rotating shaft 21 to move in a direction closer to the first adjusting element 31.

[0096] The fixing member 36 can be fixed to the side of the massage assembly 40 away from the first adjusting member 31 via the housing 10, or the fixing member 36 can be fixed to the side of the rotating shaft 21 away from the first adjusting member 31 via the housing 10. One end of the elastic member 35 is connected to the fixing member 36, and the other end can be connected to the massage assembly 40 or the rotating shaft 21. In this way, when the massage assembly 40, the second adjusting member 32, and the rotating shaft 21 move in the direction away from the first adjusting member 31 in the above manner, the elastic member 35 can be in a compressed state. During the rotation of the second adjusting member 32, the second adjusting member 32 does not always move in the direction away from the first adjusting member 31. When the second adjusting member 32 rotates to a preset position, the second adjusting member 32 can move closer to the first adjusting member 31. At this time, the elastic member 35 in a compressed state can drive the massage assembly 40, the second adjusting member 32, and the rotating shaft 21 to move in the direction closer to the first adjusting member 31, thereby realizing the return of the massage assembly 40 and the second adjusting member 32 to their original positions.

[0097] In summary, this embodiment utilizes the cooperation between the second adjusting member 32 and the first adjusting member 31 to move the massage assembly 40 in a direction away from the first adjusting member 31. Furthermore, the rebound force of the elastic member 35 is used to reset the massage assembly 40.

[0098] Please refer to this as well. Figures 8-9 ,as well as Figure 18 , Figure 18 for Figure 8 The diagram shows a cross-sectional view of the rotating shaft, adjusting assembly, two massage components, and part of the housing. In this embodiment, the second adjusting member 32 is provided with a receiving groove 320, the opening of which faces the first adjusting member 31, and the one-way bearing 33 is disposed within the receiving groove 320. The rotating shaft 20 includes two separate rotating shaft portions 21, each massage component 40 is sleeved on one of the rotating shaft portions 21, and the one-way bearing 33 is sleeved on the rotating shaft portion 21. The massage components 40, the one-way bearing 33, and the second adjusting member 32 are all axially confined within the rotating shaft portion 21. When the second adjusting member 32 moves in a direction away from the first adjusting member 31, it causes the rotating shaft portion 21 to also move in a direction away from the first adjusting member 31, and the rotating shaft portion 21 causes the one-way bearing 33 and the massage component 40 to also move in a direction away from the first adjusting member 31.

[0099] In this embodiment, a receiving groove 320 can also be formed on the second adjusting member 32, and the one-way bearing 33 can be disposed in the receiving groove 320, which can make the structure of the massage mechanism 1 more compact and achieve miniaturization. However, in this embodiment, the opening direction of the receiving groove 320 faces the first adjusting member 31, thereby simplifying the structure of the second adjusting member 32. At the same time, the rotating shaft 20 is composed of two separate rotating shaft parts 21, one massage component 40 is sleeved on one rotating shaft part 21, and the other massage component 40 is sleeved on the other rotating shaft part 21, and the one-way bearing 33 is sleeved on the rotating shaft part 21. However, the axial direction of the massage component 40, the one-way bearing 33, and the second adjusting member 32 is limited to the rotating shaft part 21, that is, the massage component 40, the one-way bearing 33, and the second adjusting member 32 cannot move axially on the rotating shaft part 21.

[0100] When the second adjusting member 32 moves axially away from the first adjusting member 31, it can drive the rotating shaft 21 to also move axially away from the first adjusting member 31. This, in turn, drives the one-way bearing 33 and the massage component 40 to move axially away from the first adjusting member 31, thus achieving the function of spacing adjustment. By having the rotating shaft 21 move as a whole through the second adjusting member 32, the massage component 40 can be moved. This eliminates the need for the second adjusting member 32 to come into contact with the massage component 40, allowing their positions to be arbitrarily set, which facilitates the position design of the massage component 40.

[0101] In this embodiment, the adjusting assembly 30 further includes a limiting member 37. The limiting member 37 includes a connecting portion 371 and an abutting portion 372 protruding from the peripheral side of the connecting portion 371. The connecting portion 371 is disposed within the one-way bearing 33 and connected to the rotating shaft portion 21. The abutting portion 372 abuts against the end side of the one-way bearing 33. When the rotating shaft portion 21 moves in a direction away from the first adjusting member 31, it causes the limiting member 37 to also move in a direction away from the first adjusting member 31. This, in turn, causes the one-way bearing 33 to move in a direction away from the first adjusting member 31 via the abutting portion 372.

[0102] The adjusting assembly 30 may also be equipped with a limiting member 37, which consists of a connecting part 371 and an abutting part 372. The connecting part 371 is rod-shaped, and the abutting part 372 protrudes from the peripheral side of the connecting part 371. The connecting part 371 can be disposed within the one-way bearing 33 and fixedly connected to the rotating shaft 21, while the two abutting parts 372 abut against the end side of the one-way bearing 33. Optionally, the limiting member 37 can be understood as a screw, which can be disposed within the one-way bearing 33 and threadedly connected to the rotating shaft 20, with the screw nut abutting against the end side of the one-way bearing 33.

[0103] When the rotating shaft 21 moves away from the first adjusting member 31, the limiting member 37 also moves away from the first adjusting member 31, and then the one-way bearing 33 moves away from the first adjusting member 31 via the abutment part 372. In this embodiment, the one-way bearing 33 and the rotating shaft 21 are axially limited together by the limiting member 37, thereby controlling the axial movement of the one-way bearing 33 by the limiting member 37.

[0104] In this embodiment, the adjusting component 30 further includes an elastic element 35. The elastic element 35 is disposed on the side of the massage component 40 or the rotating shaft portion 21 opposite to the first adjusting component 31. One end of the elastic element 35 is connected to the inner sidewall of the housing 10, and the other end is connected to the massage component 40 or the rotating shaft portion 21. When the massage component 40, the second adjusting component 32, and the rotating shaft portion 21 move in a direction away from the first adjusting component 31, the elastic element 35 is in a compressed state. When the second adjusting component 32 rotates relative to the first adjusting component 31 to a preset position, the compressed elastic element 35 can drive the massage component 40, the second adjusting component 32, and the rotating shaft portion 21 to move in a direction closer to the first adjusting component 31.

[0105] In this embodiment, an elastic element 35 can also be added to the adjusting assembly 30. The elastic element 35 can be located on the side of the massage assembly 40 away from the first adjusting element 31, or it can be located on the side of the rotating shaft 21 away from the first adjusting element 31. One end of the elastic element 35 can be connected to the inner wall of the housing 10, and the other end can be connected to the massage assembly 40 or the rotating shaft 21. Thus, when the massage assembly 40, the second adjusting element 32, and the rotating shaft 21 move in a direction away from the first adjusting element 31, the elastic element 35 is in a compressed state. During the rotation of the second adjusting element 32, the second adjusting element 32 does not always move in a direction away from the first adjusting element 31. When the second adjusting element 32 rotates to a preset position, it can move closer to the first adjusting element 31. At this time, the elastic element 35, which is in a compressed state, can drive the massage assembly 40, the second adjusting element 32, and the rotating shaft 21 to move in a direction closer to the first adjusting element 31.

[0106] In summary, this embodiment utilizes the cooperation between the second adjusting member 32 and the first adjusting member 31 to move the massage assembly 40 in a direction away from the first adjusting member 31. Furthermore, the rebound force of the elastic member 35 is used to reset the massage assembly 40.

[0107] Please refer to this as well. Figures 19-23 , Figure 19 This is a top view of the second adjusting member in one embodiment of this application. Figure 20 for Figure 19The diagram shows a three-dimensional structure of the second adjusting element. Figure 21 This is a top view of the first adjusting member in one embodiment of this application. Figure 22 for Figure 21 The diagram shows a three-dimensional structure of the first adjusting element. Figure 23 This is an exploded view of the first and second adjusting members in one embodiment of this application. In this embodiment, the second adjusting member 32 includes an adjusting portion 3121, which slides in conjunction with a mating portion 3111. The mating portion 3111 is configured to convert the frictional force generated between the second adjusting member 32 and the adjusting portion 3121 when the second adjusting member 32 rotates into an axial thrust, thereby pushing the second adjusting member 32 away from the second adjusting member 32.

[0108] When the rotating shaft 20 rotates in the first direction, the rotating shaft 20 drives the second adjusting member 32 to rotate synchronously. The adjusting part 3121 and the mating part 3111 slide to increase the axial distance between the second adjusting member 32 and the first adjusting member 31, thereby bringing the two massage components 40 closer to each other.

[0109] When the shaft 20 rotates in the second direction, the second adjusting member 32 may not rotate with the shaft 20. That is, when the shaft 20 rotates in the second direction, the second adjusting member 32 no longer pushes the second adjusting member 32 to move in a direction away from the first adjusting member 31.

[0110] The adjusting part 3121 and the mating part 3111 slide together. When the second adjusting part 32 rotates with the rotating shaft 20, the two surfaces of the adjusting part 3121 and the mating part 3111 that abut against each other slide relative to each other. The friction force generated by the relative rotation of the adjusting part 3121 and the mating part 3111 is converted into an axial thrust on the adjusting part 3121 by the inclined surface of the mating part, thereby pushing the second adjusting part 32 to move axially, so as to drive the massage component 40 to move axially, thereby achieving the purpose of adjusting the distance between the two massage components 40.

[0111] In this embodiment, at least one of the adjusting part 3121 and the mating part 3111 includes a guide slope, which extends spirally along the axial direction of the rotating shaft 20.

[0112] At least one of the adjusting part 3121 and the mating part 3111 includes a guide slope that extends spirally along the axial direction of the rotating shaft 20. If only one of the adjusting part 3121 and the mating part 3111 has a guide slope, the one of the adjusting part 3121 and the mating part 3111 that does not include a guide slope can abut against the other.

[0113] When the adjusting part 3121 rotates in the first direction, the part excluding the guide ramp can climb and slide on the guide ramp, so that the guide ramp converts the frictional force generated by the rotation into an axial thrust, thereby pushing the second adjusting member 32 gradually away from the first adjusting member 31. The part excluding the guide ramp can be configured as a limiting protrusion.

[0114] When both the adjusting part 3121 and the mating part 3111 include guide slopes, the guide slopes of the adjusting part 3121 and the mating part 3111 can abut against each other. The adjusting part 3121 abuts against the guide slope of the mating part 3111 through its own guide slope. When the adjusting part 3121 rotates in the first direction, the adjusting part 3121 can climb and slide along the guide slope of the mating part 3111 to realize the axial movement of the adjusting part 3121, thereby driving the massage assembly 40 to move axially to adjust the distance between the two massage assemblies 40.

[0115] In this embodiment, both the adjusting part 3121 and the mating part 3111 include guide slopes. The guide slope of the mating part 3111 is the mating slope 3116, and the guide slope of the adjusting part 3121 is the adjusting slope 3125. The mating slope 3116 and the adjusting slope 3125 are arranged opposite to each other.

[0116] When the rotating shaft 20 rotates in the first direction, the adjusting slope 3125 abuts against the mating slope 3116 and slides along the mating slope 3116, thereby allowing the adjusting part 3121 to move away from the mating part 3111 axially, thereby driving the massage assembly 40 to move axially to adjust the distance between the two massage assemblies 40.

[0117] Meanwhile, because the user exerts a significant reaction force on the massage components 40 during operation, this reaction force hinders the two massage components 40 from approaching each other. Therefore, the process of separating the second adjusting member 32 from the first adjusting member 31 also requires overcoming this reaction force. By forming an adjusting slope 3125 on the adjusting part 3121 and a mating slope 3116 on the mating part 3111, the sliding fit between the second adjusting member 32 and the first adjusting member 31 can be made more stable, thereby overcoming the significant reaction force and ensuring the reliability of the distance adjustment of the massage components 40.

[0118] In this embodiment, the adjusting part 3121 includes a first limiting surface 3127 extending axially along the rotating shaft 20, and the first limiting surface 3127 is connected to the adjusting inclined surface 3125; the mating part 3111 includes a second limiting surface 3115 extending axially along the rotating shaft 20, and the second limiting surface 3115 is connected to the adjusting inclined surface 3125; when the rotating shaft 20 is driven to rotate in the second direction, the first limiting surface 3127 and the second limiting surface 3115 limit each other to prevent the second adjusting member 32 from rotating relative to the first adjusting member 31.

[0119] Specifically, when it is necessary to adjust the distance between the two massage components 40, the motor and other drive components 50 can drive the rotating shaft 20 to rotate in the first direction, and the guide slope of the adjusting part 3121 can slide along the guide slope of the mating part 3111 to move away from the mating part 3111, so that the second adjusting part 32 gradually moves away from the first adjusting part 31.

[0120] When no adjustment is needed, the motor and other drive components 50 can drive the rotating shaft 20 to rotate in the second direction. At this time, the second adjustment member 32 does not rotate with the rotating shaft 20. Under the force of the elastic member 35 acting on the massage assembly 40, the adjustment slope 3125 of the adjustment part 3121 can slide along the mating slope 3116 of the mating part 3111 and move closer to the first adjustment member 31 until the second adjustment member 32 moves back to its initial position. At this time, the first limiting surface 3127 of the adjustment part 3121 and the second limiting surface 3115 of the mating part 3111 mutually limit each other, and the second adjustment member 32 will no longer adjust the distance when the rotating shaft 20 continues to rotate in the second direction. When the rotating shaft 20 rotates in the first direction again, the second adjustment member 32 can move away from the first adjustment member 31 again to adjust the distance between the two massage assemblies 40.

[0121] In this embodiment, the adjusting part 3121 includes a plurality of adjusting teeth 3122 arranged circumferentially along the rotation axis 20, and the adjusting inclined surface 3125 includes the adjusting tooth surface 3123 of each adjusting tooth 3122. Along the first direction, the distance from the tooth tip of the plurality of adjusting teeth 3122 to the second adjusting member 32 away from the first end face 3128 of the first adjusting member 31 gradually decreases. The mating part 3111 includes a plurality of mating teeth 3112 arranged circumferentially along the rotation axis 20, and the mating inclined surface 3116 includes the mating tooth surface 3113 of each mating tooth 3112. Along the first direction, the distance from the tooth tip of the plurality of mating teeth 3112 to the first adjusting member 31 away from the second end face 3114 of the second adjusting member 32 gradually increases, thereby forming multiple gear positions when the second adjusting member 32 rotates relative to the first adjusting member 31.

[0122] In this configuration, the mating teeth 3112 and the adjusting teeth 3122 are adapted to each other, and the number of mating teeth 3112 is the same as the number of adjusting teeth 3122. When the rotating shaft 20 rotates in the first direction, one adjusting tooth 3122 can slide relative to one mating tooth 3112 in the first direction and mesh with the next mating tooth 3112, thereby completing one gear adjustment. As the rotating shaft 20 continues to rotate in the first direction, this adjusting tooth 3122 meshes with multiple mating teeth 3112 respectively, thereby completing the switching of various gears.

[0123] Furthermore, when adjusting the distance between the two massage components 40, when the user wishes to stop adjusting the distance at a suitable target level, the angle sensor configured in the massage mechanism 1 can obtain the current rotation angle of the first rotating component, so that the rotating shaft 20 stops rotating at a suitable rotation angle, thereby stopping the second adjusting component 32 at the position where the mating teeth 3112 and the adjusting teeth 3122 corresponding to the target level are engaged with each other. The adjusting teeth 3122 and the mating teeth 3112 are engaged and locked together to form a limiting fit.

[0124] Meanwhile, the elastic member 35 can apply a pushing force to one massage component 40 that is away from the other massage component 40, thereby further ensuring that the second adjusting member 32 is fixed relative to the first adjusting member 31 so that the massage component 40 no longer moves at the current setting.

[0125] It is understandable that, as the distance between the tooth tip of the mating tooth 3112 and the first adjusting member 31 gradually increases, when the second adjusting member 32 rotates in the first direction, one adjusting tooth 3122 can slide along the adjacent mating tooth 3112 in sequence, thereby causing the second adjusting member 32 to gradually move away from the first adjusting member 31.

[0126] Thus, the massager using the massage mechanism 1 can have multiple levels of adjustment based on the distance between the two massage components 40, and the adjustment can be switched by rotating the shaft 20 in the first direction, making the massager adaptable to users of various body types and thus improving the user experience.

[0127] In this embodiment, the axial distance between the two ends of the adjusting tooth surface 3123 of each adjusting tooth 3122 is the adjusting tooth height, and the adjusting tooth heights of two adjacent adjusting teeth 3122 are the same. The axial distance between the two ends of the mating tooth surface 3113 of each mating tooth 3112 is the mating tooth height, and the mating tooth heights of two adjacent mating teeth 3112 are the same.

[0128] The axial distance between the two ends of each adjusting tooth surface 3123 is equal to the tooth height of the adjusting tooth 3122, and the tooth heights of each adjusting tooth 3122 are equal. Correspondingly, the mating inclined surface 3116 includes mating tooth surfaces 3113 of multiple mating teeth 3112, the axial distance between the two ends of each mating tooth surface 3113 is equal to the tooth height of the mating tooth 3112, and the tooth heights of each mating tooth 3112 are equal.

[0129] In this way, the two adjacent adjusting teeth 3122 have the same adjusting tooth height, which ensures that when adjusting the distance between the two massage components 40, the adjustment amount of each gear is equal, so that the user can get a stable and predictable adjustment effect, thereby improving the efficiency of adjusting the distance.

[0130] In this embodiment, the pitch-adjusting tooth surface 3123 has an inclination angle relative to the axis of the rotating shaft 20, and the inclination angle θ satisfies: 3°≤θ≤45°; and / or the axial distance L between the two ends of the pitch-adjusting inclined surface 3125 satisfies 2mm≤L≤20mm.

[0131] If the slope of the adjusting tooth surface 3123 of each adjusting tooth 3122 is too large, a large torque is required for the adjusting tooth 3122 to move along the mating slope 3116 on the mating tooth 3112 and mesh with the next mating tooth 3112. This may cause the second adjusting member 32 to have difficulty moving relative to the first adjusting member 31, resulting in jamming during the adjusting process. Conversely, if the slope of the adjusting tooth surface 3123 of each adjusting tooth 3122 is too small, the gear adjustment effect will be insignificant, reducing the efficiency of the adjusting process. Therefore, the tilt angle θ of the adjusting tooth surface 3123 relative to the axis of the rotating shaft 20 needs to satisfy: 3°≤θ≤45°.

[0132] Specifically, the tilt angle θ of the pitch-adjusting tooth surface 3123 relative to the axis of the rotating shaft 20 can be 3°, 10°, 20°, 30° or 45°.

[0133] Meanwhile, the adjustable range of the massage component 40 is limited to 2mm≤L≤20mm. This range can adapt to the body shape of most users, so that the massage mechanism 1 can meet the usage needs of most customers.

[0134] Specifically, the axial distance L between the two ends of the adjustable inclined plane 3125 can be 2mm, 3mm, 9mm, 10mm, or 20mm.

[0135] In addition, the adjustable range of the massage component 40 is limited to 2mm≤L≤20mm, which means that the axial adjustment value of each gear of the adjusting tooth 3122 can be between 0.5mm and 5mm, so that the adjustment amount of each gear is relatively consistent and will not be adjusted too large or too small at one time, so as to ensure the efficiency of the user when adjusting the two massage components 40.

[0136] In this embodiment, the first limiting surface 3127 is connected to the adjusting tooth surface 3123 of the first adjusting tooth 3122, and the first adjusting tooth 3122 is the adjusting tooth 3122 with the largest distance from the first end face 3128. The first limiting surface 3127 is connected to the mating tooth surface 3113 of the first mating tooth, and the first mating tooth is the mating tooth 3112 with the largest distance from the second end face 3114.

[0137] It can be understood that the first adjusting tooth 3122 is the adjusting tooth 3122 with the largest distance from the first end face 3128. The first limiting surface 3127 is connected to the adjusting tooth surface 3123 of the first adjusting tooth 3122. That is, the first limiting surface 3127 limits the final position of the second adjusting member 32 relative to the first adjusting member 31 for multi-level adjustment.

[0138] Furthermore, the second adjusting tooth 3122 is the adjusting tooth 3122 with the smallest distance from the first end face 3128, and the second mating tooth is the mating tooth 3112 with the smallest distance from the second end face 3114.

[0139] As the first adjusting tooth 3122 slides sequentially from the second mating tooth to the first mating tooth, the distance between the second adjusting member 32 and the first adjusting member 31 gradually increases. Since the mating tooth surface 3113 of the first mating tooth is connected to the second limiting surface 3115, when the rotating shaft 20 continues to rotate in the first direction, when the first adjusting tooth 3122 abuts against the connection between the first mating tooth and the first limiting surface 3127, the distance between the second adjusting member 32 and the first adjusting member 31 is at its farthest, and the second adjusting member 32 reaches its limit position for adjusting. If the rotating shaft 20 continues to rotate in the first direction, the first adjusting tooth 3122 will fall off the first mating tooth, and the second adjusting member 32 will move closer to the first adjusting member 31 and move back to its initial position, returning to the setting where the distance between the two massage components 40 is at its farthest, and then readjust the distance between the two massage components 40 according to the user's needs.

[0140] In this embodiment, the first adjusting member 31 includes two mating parts 3111, and the two mating parts 3111 are symmetrically arranged with respect to the axis of the rotating shaft 20. The second adjusting member 32 includes two adjusting parts 3121, and the two adjusting parts 3121 are symmetrically arranged with respect to the axis of the rotating shaft 20.

[0141] The two mating parts 3111 and the two adjusting parts 3121 are symmetrically arranged with respect to the axis of the rotating shaft 20, which can balance the force between the second adjusting member 32 and the first adjusting member 31, and make the external force on the two mating parts 3111 and the two adjusting parts 3121 evenly distributed. This prevents the second adjusting member 32 from tilting to one side due to uneven force, which would affect the adjusting effect or even cause the second adjusting member 32 to jam.

[0142] At the same time, an axial height difference is formed between the connection positions of the two adjusting parts 3121 and the connection positions of the two mating parts 3111. This allows each second adjusting member 32 to fall back to its initial position from the first adjusting member 31 after being adjusted to the position closest to the two massage components 40. That is, the position where the adjusting member is close to the first adjusting member 31. Then, the next gear adjustment can be started by rotating the rotating shaft 20, making the adjustment process more continuous and improving the user experience.

[0143] Furthermore, the arrangement of two adjusting parts 3121 and two mating parts 3111 can shorten the adjusting process. The rotating shaft 20 only needs to rotate 180° in the first direction to complete the adjusting process, thereby improving the adjusting efficiency of the adjusting assembly 30.

[0144] In this embodiment, the second adjusting member 32 includes a support portion 3129, two adjusting portions 3121 are disposed on the outer periphery of the support portion 3129, at least a portion of the support portion 3129 is exposed on the adjusting portion 3121 along the axial direction of the rotating shaft 20, and the mating portion 3111 can be sleeved on the support portion 3129.

[0145] The mating portion 3111 of the first adjusting member 31 can surround the support portion 3129 of the second adjusting member 32, so that the mating portion 3111 can also limit the second adjusting member 32 in the radial direction of the rotating shaft 20 and the first adjusting member 31, so as to avoid excessive radial offset of the second adjusting member 32 and wear between the second adjusting member 32 and the rotating shaft 20. At the same time, the mating portion 3111 sleeved on the support portion 3129 can enable the support portion 3129 to support the mating portion 3111, preventing the mating portion 3111 from shaking under the influence of external forces.

[0146] Please refer to Figure 24 , Figure 24 for Figure 1 The diagram shows a three-dimensional structure of the massage mechanism after the housing has been removed. In this embodiment, the massage mechanism 1 also includes a gear set 60, which is connected to the output shaft of the drive member 50. The output shaft of the drive member 50 is perpendicular to the axial direction of the rotating shaft 20. A bevel gear assembly 61 is sleeved on the rotating shaft 20 and is connected to the gear set 60.

[0147] The drive component 50 is connected to the gear set 60 via an output shaft. The rotation of the output shaft of the drive component 50 drives the gear set 60 to rotate, which in turn drives the bevel gear assembly 61 to rotate. The output shaft of the drive component 50 is perpendicular to the axis of the rotating shaft 20. The bevel gear assembly 61 can change the rotation direction of the output shaft of the drive component 50, thereby driving the rotating shaft 20 to rotate, thus realizing the drive component 50 driving the rotating shaft 20.

[0148] Optionally, the gear set 60 may include a first transmission gear and a second transmission gear. The first transmission gear is connected to the output shaft of the drive member 50, and the second transmission gear is meshed with the first transmission gear, so that the first transmission gear can rotate under the drive of the drive member 50 to drive the rotation of the second transmission gear.

[0149] Optionally, the bevel gear assembly 61 may include a first bevel gear 611 and a second bevel gear 612. The first bevel gear 611 is meshed with a second transmission gear, and the second bevel gear 612 is meshed with the first bevel gear 611, so that the first bevel gear 611 can rotate with the second transmission gear to drive the second bevel gear 612 to rotate.

[0150] The first bevel gear 611 is sleeved on the rotating shaft 20. The rotating shaft 20 may be provided with a limiting part that cooperates with the first bevel gear 611, so that the first bevel gear 611 and the rotating shaft 20 are connected in a transmission manner, so that the first bevel gear 611 can drive the rotating shaft 20 to rotate, thereby achieving the purpose of the driving member 50 driving the rotating shaft 20 to rotate.

[0151] In this embodiment, the massage assembly 40 includes a first eccentric wheel 41, a second eccentric wheel 43, and a massage head 42 sandwiched between the first eccentric wheel 41 and the second eccentric wheel 43. The first eccentric wheel 41 and the second eccentric wheel 43 are in a limiting engagement with the rotating shaft 20.

[0152] The first eccentric wheel 41 and the second eccentric wheel 43 are engaged with the rotating shaft 20 to limit their movement, thereby enabling the first eccentric wheel 41 and the second eccentric wheel 43 to rotate synchronously with the rotating shaft 20. The first eccentric wheel 41 and the second eccentric wheel 43 have inclined surfaces, and the massage head 42 is sandwiched between the first eccentric wheel 41 and the second eccentric wheel 43. When the rotating shaft 20 rotates, the first eccentric wheel 41 and the second eccentric wheel 43 rotate, and the inclined surfaces of the first eccentric wheel 41 and the second eccentric wheel 43 can push the massage head 42 sandwiched in the middle to swing, thereby achieving the purpose of massage component 40 performing massage.

[0153] In this embodiment, the two massage components 40 are symmetrically arranged relative to the center of the rotating shaft 20. This symmetrical arrangement ensures that the two massage components 40 receive even pressure during massage, avoiding user discomfort caused by asymmetry between the two components, thereby improving user comfort and satisfaction. Simultaneously, the symmetrical massage components 40 can evenly apply pressure to the user's body, optimizing the massage effect.

[0154] This embodiment provides a massager, which includes a massage mechanism 1 as described in the above-described embodiments of this application. The detailed structure of the massage mechanism 1 has been described in detail above and will not be repeated here. The massager provided in this embodiment, by employing the massage mechanism 1 described in the above-described embodiments of this application, fixes a first adjusting member 31 to the housing 10 and a second adjusting member 32 to the rotating shaft 20. When the rotating shaft 20 rotates in a first direction, it drives the second adjusting member 32 to rotate synchronously, causing the second adjusting member 32 to rotate relative to the first adjusting member 31. This allows the second adjusting member 32 to move along the axial direction of the rotating shaft 20, thereby adjusting the distance between the two massage components 40 and achieving the function of adjusting the distance. However, since the first adjusting member 31 is fixed to the housing 10, it remains stationary. When the shaft 20 rotates in the opposite second direction, the shaft 20 will no longer drive the second adjusting member 32 to rotate. The second adjusting member 32 is stationary relative to the shaft 20 in the axial direction of the shaft 20. That is, the second adjusting member 32 and the first adjusting member 31 are both fixed. At this time, only the shaft 20 rotates relative to the second adjusting member 32.

[0155] In summary, compared to related technologies, the first adjusting member 31 generates significant noise when rotating relative to the housing 10, and both the first adjusting member 31 and the housing 10 are prone to wear, reducing their service life. This embodiment adjusts the relative rotation to the position between the rotating shaft 20 and the second adjusting member 32. The relative rotation between the rotating shaft 20 and the second adjusting member 32 reduces noise, and the rotating shaft 20 and the second adjusting member 32 are less prone to wear, thus increasing their service life.
