Description

Technical Field

[0001] This application relates to the field of massage device technology, and in particular to a massage mechanism and a massage device. Background Technology

[0002] With the rapid pace of modern life and work, people spend long hours immersed in work or lack sufficient physical activity, leading to muscle tension and poor blood circulation in areas such as the neck, shoulders, waist, and legs. This can result in conditions like frozen shoulder, cervical spondylosis, and lower back and leg pain. Against this backdrop, massage devices, as convenient health aids, are gaining popularity due to their ability to effectively relieve physical fatigue.

[0003] However, most massage devices on the market today only provide massage services through rotation or oscillation, failing to fully consider the differences in neck, shoulder, waist, and leg width among different users, and lacking personalized spacing adjustment functions, which affects the user experience and the full realization of the massage effect. Summary of the Invention

[0004] This application discloses a massage mechanism and massager, which can adjust the spacing between massage components, allowing the massager to adapt to different body parts of different users, effectively improving the applicability and comfort of the massage mechanism and massager.

[0005] To achieve the above objectives, embodiments of this application provide a massage mechanism, comprising: a massage mechanism including a first massage component and a second massage component; a rotating shaft, wherein the first massage component and the second massage component are slidably sleeved on the rotating shaft and spaced apart along the axial direction of the rotating shaft; an adjusting mechanism sleeved on the rotating shaft and axially disposed outside the first massage component and the second massage component; and a driving member configured to drive the massage mechanism to move, and / or the driving member configured to drive the adjusting mechanism to adjust the distance between the first massage component and the second massage component.

[0006] As an optional implementation, the adjusting mechanism includes: a first adjusting component sleeved on the first end of the rotating shaft, the first adjusting component abutting against the first side of the first massage component, the first side of the first massage component being opposite to the second massage component; a second adjusting component sleeved on the second end of the rotating shaft, the second adjusting component abutting against the first side of the second massage component, the first side of the second massage component being opposite to the first massage component; when the driving member drives the rotating shaft to rotate in a first direction, the first adjusting component and the second adjusting component are configured to drive the first massage component and the second massage component to move closer to each other.

[0007] As an optional implementation, the massage mechanism further includes an elastic component for applying a restoring force to the first massage component and the second massage component, distancing them from each other.

[0008] As an optional implementation, the massage mechanism further includes a housing for accommodating the adjustment mechanism.

The first adjustment component includes: a base fixed relative to the housing; and an adjustment member slidably disposed on the rotating shaft and abutting against the first massage component, the adjustment member being capable of sliding engagement with the base. When the rotating shaft rotates in a first direction, the rotating shaft drives the adjustment member to rotate synchronously, and the adjustment member slides with the base to increase the axial distance between the base and the adjustment member, thereby bringing the first massage component closer to the second massage component.

[0010] As an optional implementation, the adjusting member includes an adjusting part that slides into a mating part. The mating part is configured to convert the frictional force generated between the adjusting member and the adjusting part when the adjusting member rotates into an axial thrust to push the adjusting member away from the adjusting member.

[0011] As an optional implementation, at least one of the adjusting part and the mating part includes a guide slope that extends spirally along the axial direction of the rotating shaft; when the rotating shaft rotates in the first direction, the adjusting part and the mating part abut against each other and slide through the guide slope to move the adjusting member away from the base.

[0012] As an optional implementation, both the adjusting part and the mating part include guide slopes, wherein the guide slope of the mating part is a mating slope, and the guide slope of the adjusting part is an adjusting slope, and the mating slope and the adjusting slope are arranged opposite to each other; when the rotating shaft rotates in the first direction, the adjusting slope abuts against the mating slope and slides along the adjusting slope.

[0013] As an optional implementation, the adjusting part includes a first limiting surface extending axially along the rotation shaft, and the first limiting surface is connected to the adjusting inclined surface; the mating part includes a second limiting surface extending axially along the rotation shaft, and the second limiting surface is connected to the adjusting inclined surface; when the driving member drives the rotation shaft to rotate in the second direction, the first limiting surface and the second limiting surface limit each other to prevent the adjusting member from rotating relative to the base.

[0014] As an optional implementation, the adjusting part includes a plurality of adjusting teeth arranged circumferentially along the rotation axis, and the adjusting inclined surface includes the adjusting tooth surface of each adjusting tooth. Along the first direction, the distance from the tooth tip of the plurality of adjusting teeth to the first end face of the adjusting member away from the base gradually decreases. The mating part includes a plurality of mating teeth arranged circumferentially along the rotation axis, and the mating inclined surface includes the mating tooth surface of each mating tooth. Along the first direction, the distance from the tooth tip of the plurality of mating teeth to the second end face of the base away from the adjusting member gradually increases. The mating teeth are adapted to the adjusting teeth, and the number of mating teeth is the same as the number of adjusting teeth.

[0015] As an optional implementation, the axial distance between the two ends of the adjusting tooth surface of each adjusting tooth is the adjusting tooth height, and the adjusting tooth height of two adjacent adjusting teeth is the same; and the axial distance between the two ends of the mating tooth surface of each mating tooth is the mating tooth height, and the mating tooth height of two adjacent mating teeth is the same.

[0016] As an optional implementation, the pitch-adjusting tooth surface has an inclination angle relative to the axis of the rotating shaft, the inclination angle θ satisfying: 3°≤θ≤45°; and / or the axial distance L between the two ends of the pitch-adjusting inclined surface satisfies 2mm≤L≤20mm.

[0017] As an optional implementation, the first limiting surface is connected to the adjusting tooth surface of the first adjusting tooth, and the first adjusting tooth is the adjusting tooth with the largest distance from the first end face; the second limiting surface is connected to the mating tooth surface of the first mating tooth, and the first mating tooth is the mating tooth with the largest distance from the second end face.

[0018] As an optional implementation, the base includes two mating parts, which are symmetrically arranged with respect to the axis of rotation; the adjusting member includes two adjusting parts, which are symmetrically arranged with respect to the axis of rotation.

[0019] As an optional implementation, the adjusting member includes a support portion, two adjusting portions are disposed on the outer periphery of the support portion, at least a portion of the support portion is exposed outward along the axial direction of the rotation axis of the adjusting portion, and a mating portion can be sleeved on the support portion.

[0020] As an optional implementation, the massage mechanism further includes a clutch component disposed between the rotating shaft and the adjusting component. The clutch component is capable of driving the adjusting component to rotate synchronously with the rotating shaft when the rotating shaft rotates in a first direction, and of keeping the adjusting component stationary when the rotating shaft rotates in a second direction.

[0021] As an optional implementation, the clutch includes a one-way bearing, which is sleeved on the rotating shaft, and the adjusting element is sleeved on the rotating shaft via the one-way bearing.

[0022] As an optional implementation, the massage mechanism further includes a metal sleeve fitted over the outside of the rotating shaft and positioned between the clutch and the rotating shaft.

[0023] As an optional implementation, the massage mechanism further includes: a gear set, which is connected to the output shaft of the drive component, the output shaft of the drive component being perpendicular to the axis of the rotating shaft; and a bevel gear assembly, which is sleeved on the rotating shaft and connected to the gear set.

[0024] As an optional implementation, the first massage assembly includes a first eccentric wheel, a second eccentric wheel, and a first massage head sandwiched between the first eccentric wheel and the second eccentric wheel. The first eccentric wheel and the second eccentric wheel are in a limiting engagement with the rotating shaft. When the first eccentric wheel and the second eccentric wheel rotate with the rotating shaft, they cause the first massage head to swing.

[0025] As an optional implementation, the first massage component and the second massage component are respectively arranged symmetrically with respect to the center of the rotation axis.

[0026] A second aspect of this application provides a massager including a massage mechanism.

[0027] Compared with the prior art, the beneficial effects of this application are:

[0028] The massage mechanism includes a first massage component, a second massage component, and a rotating shaft. The first and second massage components are slidably disposed on the rotating shaft along the axial direction. An adjustment mechanism located outside the first and second massage components can cooperate with a drive component to push the first and second massage components closer to each other along the axial direction, thereby adjusting the distance between the first and second massage components disposed on the rotating shaft. This allows the massager using the massage mechanism to adapt to users with different body shapes and meet the personalized needs of users. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In this application, the terms "upper," "lower," "top," "bottom," "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0045] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0046] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0048] 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, shoulders, lower back, and legs. 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 chronic pain from frozen shoulder, degenerative changes in the cervical spine due to cervical spondylosis, and lower back and leg pain, severely impacting people's quality of life.

[0049] Massagers 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.

[0050] 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.

[0051] To address the aforementioned issues, the inventors investigated the limitations of existing massage devices, improved upon existing massage mechanisms, and designed a massage mechanism with adjustable massage intervals, thereby enhancing the accuracy and comfort of the massage device.

[0052] Based on this, this application discloses a massage mechanism and a massager, which can solve the problem that traditional massagers cannot perform personalized spacing adjustment.

[0053] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0054] Please see Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of the massage mechanism 100 provided in the embodiments of this application. Figure 2 This is a second structural schematic diagram of the massage mechanism 100 provided in this application embodiment. This application embodiment discloses a massage mechanism 100, comprising: a massage mechanism 10, which includes a first massage component 101 and a second massage component 102; a rotating shaft 20, on which the first massage component 101 and the second massage component 102 are slidably sleeved and spaced apart along the axial direction of the rotating shaft 20; an adjusting mechanism 30, sleeved on the rotating shaft 20, axially positioned outside the first massage component 101 and the second massage component 102; and a driving member 50 configured to drive the massage mechanism 10 to move, and / or the driving member 50 configured to drive the adjusting mechanism to adjust the distance between the first massage component 101 and the second massage component 102.

[0055] The massage mechanism 10 of the massage core 100 includes a first massage component 101 and a second massage component 102, which can simultaneously massage the left and right shoulders and neck of the user.

[0056] When the first massage component 101 and the second massage component 102 work simultaneously, they can form complex massage movements similar to human hand kneading, which not only enhances the intensity and depth of the massage, but also makes the massage process more natural and smooth.

[0057] Optionally, the first massage component 101 and the second massage component 102 can perform massage by swinging or rotating, or by vibrating or tapping, and can also add functions such as hot compress or magnetic therapy to improve the massage effect.

[0058] The massage mechanism 100 also includes a rotating shaft 20. The first massage component 101 and the second massage component 102 are slidably sleeved on the rotating shaft 20 and are spaced apart along the axial direction of the rotating shaft 20. Both the first massage component 101 and the second massage component 102 are movable along the axial direction of the rotating shaft 20, so that the distance between the first massage component 101 and the second massage component 102 changes.

[0059] When the rotating shaft 20 rotates, a portion of the first massage assembly 101 and the second massage assembly 102 can rotate along with the rotation of the rotating shaft 20, thereby enabling the massage heads on the first massage assembly 101 and the second massage assembly 102 to oscillate and knead the user's shoulders.

[0060] At the same time, the rotating shaft 20 can also support the first massage component 101 and the second massage component 102, preventing the first massage component 101 and the second massage component 102 from shaking due to the reaction force during operation, thus affecting the massage effect.

[0061] The first massage component 101 and the second massage component 102 share a single rotating shaft 20. The rotating shaft 20 can provide structural support for the first massage component 101 and the second massage component 102, and it can also provide power for the swinging of the first massage component 101 and the second massage component 102. The single rotating shaft 20 can make reasonable use of the internal space of the massage mechanism 100 to ensure the structural compactness of the massage mechanism 100.

[0062] The adjusting mechanism 30 is sleeved on the rotating shaft 20. The adjusting mechanism 30 is axially located on the outside of the first massage component 101 and the second massage component 102, so that the adjusting mechanism 30 can push the first massage component 101 and the second massage component 102 to move inward, thereby adjusting the axial distance between the first massage component 101 and the second massage component 102, so as to realize the adjustment of the massage distance and improve the applicability and comfort of the massage mechanism 100.

[0063] It is understood that when the rotating shaft 20 rotates, it drives the adjusting mechanism 30 to move, thereby causing the adjusting mechanism 30 to push the first massage component 101 and the second massage component 102 to move axially. When the adjusting mechanism 30 pushes the first massage component 101, the first massage component 101 moves towards the second massage component 102 along the rotating shaft 20. When the adjusting mechanism 30 pushes the second massage component 102, the second massage component 102 moves towards the first massage component 101 along the rotating shaft 20, thereby enabling the first massage component 101 and the second massage component 102 to move closer to each other axially, so as to realize the adjustment of the distance between the adjusting mechanism 30 and the massage mechanism 10.

[0064] The drive unit 50 can be used to drive the rotating shaft 20 to rotate, thereby driving the massage mechanism 10 to move, so as to drive the first massage component 101 and the second massage component 102 to swing or rotate, so as to achieve the massage effect.

[0065] The drive member 50 can be used to drive the adjustment mechanism 30 to move, so that the adjustment mechanism 30 can push the first massage component 101 and the second massage component 102 to move axially under the drive of the drive member 50, so as to adjust the distance between the first massage component 101 and the second massage component 102.

[0066] The drive unit 50 can be used to drive the first massage component 101 and the second massage component 102 to swing, and at the same time, it can drive the distance adjustment mechanism 30 to adjust the distance between the first massage component 101 and the second massage component 102, so that the driving of the massage mechanism 10 and the distance adjustment mechanism 30 can be achieved by a single drive unit 50. This not only reduces the cost of the massage mechanism 100, but also makes the massage mechanism 100 more compact.

[0067] In some embodiments, the drive member 50 may be located in the middle region of the massage mechanism 100, which can make reasonable use of the space between the first massage component 101 and the second massage component 102 and optimize the structural layout of the massage mechanism 100.

[0068] Optionally, the driving component 50 may be a drive motor or other components capable of driving the massage mechanism 10 and / or the adjustment mechanism 30 to work; this embodiment does not limit this.

[0069] Thus, the massage mechanism 10 includes a first massage component 101, a second massage component 102, and a rotating shaft 20. The first massage component 101 and the second massage component 102 are slidably disposed on the rotating shaft 20 along the axial direction. The distance adjustment mechanism 30 located outside the first massage component 101 and the second massage component 102 can cooperate with the drive member 50 to push the first massage component 101 and the second massage component 102 closer to each other along the axial direction, thereby adjusting the distance between the first massage component 101 and the second massage component 102 disposed on the rotating shaft 20, so that the massager using the massage mechanism 100 can adapt to users with different body shapes and meet the personalized needs of users.

[0070] Please see Figure 2 In some embodiments, the adjusting mechanism 30 includes a first adjusting component 31, which is sleeved on the first end of the rotating shaft 20. The first adjusting component 31 abuts against the first side of the first massage component 101, and the first side of the first massage component 101 is away from the second massage component 102.

[0071] The first adjusting component 31 is sleeved on the first end of the rotating shaft 20, and at least a portion of the first adjusting component 31 can move under the drive of the rotating shaft 20. Specifically, when the rotating shaft 20 rotates in the first direction under the drive of the drive member 50, it can drive at least a portion of the first adjusting component 31 to move. Through the contact between the first adjusting component 31 and the first massage component 101, the first adjusting component 31 can push the first massage component 101 to move closer to the second massage component 102.

[0072] In some embodiments, the adjusting mechanism 30 further includes a second adjusting component 32, which is sleeved on the second end of the rotating shaft 20. The second adjusting component 32 abuts against the first side of the second massage component 102, and the first side of the second massage component 102 is away from the first massage component 101.

[0073] The second adjusting component 32 is sleeved on the first end of the rotating shaft 20, and at least a portion of the second adjusting component 32 can move under the drive of the rotating shaft 20. Specifically, when the rotating shaft 20 rotates in the first direction under the drive of the drive member 50, it can drive at least a portion of the second adjusting component 32 to move. Through the contact between the second adjusting component 32 and the second massage component 102, the second adjusting component 32 can push the second massage component 102 to move closer to the first massage component 101.

[0074] It can be understood that when the drive member 50 drives the rotating shaft 20 to rotate in the first direction, the rotating shaft 20 drives the first adjusting component 31 and the second adjusting component 32 to move, thereby pushing the first massage component 101 and the second massage component 102 closer to each other, so as to adjust the distance between the first massage component 101 and the second massage component 102.

[0075] Please see Figure 2 In some embodiments, the massage mechanism 100 further includes an elastic component 40 for applying a resetting force to the first massage component 101 and the second massage component 102 to move them away from each other.

[0076] As the first massage assembly 101 and the second massage assembly 102 approach each other axially, they compress the elastic component 40 located between them, causing the elastic component 40 to deform. When the first massage assembly 101 and the second massage assembly 102 approach each other to their limit position, the deformation of the elastic component 40 is converted into a restoring force, which pushes the first massage assembly 101 and the second massage assembly 102 back to their initial position for the next adjustment operation.

[0077] Meanwhile, as the first massage component 101 and the second massage component 102 approach each other along the axial direction, the elastic component 40 can provide a force to the first massage component 101. This force is opposite to the pushing force provided by the first adjustment component 31 to the first massage component 101. After the first adjustment component 31 pushes the first massage component 101 to reach the massage interval required by the user, the first massage component 101 can remain in its current position under the opposite forces applied by the elastic component 40 and the first adjustment component 31 to ensure the effect of the adjustment.

[0078] Similarly, as the first massage component 101 and the second massage component 102 approach each other along the axial direction, the elastic component 40 can provide a force to the second massage component 102, which is opposite to the pushing force provided by the second adjustment component 32 to the second massage component 102. After the second adjustment component 32 pushes the second massage component 102 to reach the massage interval required by the user, the second massage component 102 can remain in the current position under the opposite forces applied by the elastic component 40 and the second adjustment component 32 to ensure the effect of the adjustment.

[0079] In addition, the elastic component 40 also has a buffering effect. During the process of the first massage component 101 and the second massage component 102 approaching each other along the axial direction, the elastic component 40 can prevent the first massage component 101 and the second massage component 102 from approaching each other too quickly, which would make it difficult for the user to control the first massage component 101 and the second massage component 102 to stop in the appropriate position, thereby ensuring the accuracy of the distance adjustment and the user's experience.

[0080] Optionally, the elastic component 40 can be a spring or an elastic washer, which can generate a restoring force. This embodiment does not limit this.

[0081] like Figure 2 As shown, in some embodiments, the massage mechanism 100 further includes a housing 60 for accommodating the adjustment mechanism 30, and the elastic component 40 includes a first limiting member 41, which is fixed to the housing 60, and the rotating shaft 20 passes through the first limiting member 41.

[0082] The first limiting member 41 is fixed to the housing 60, and the rotating shaft 20 passes through the first limiting member 41. The first limiting member 41 and the rotating shaft 20 are movably connected, thereby ensuring that when the rotating shaft 20 rotates, the first limiting member 41 will not rotate with the rotating shaft 20 or move along the axial direction. At the same time, the first limiting member 41 will not hinder the rotation of the rotating shaft 20.

[0083] The elastic component 40 also includes a first elastic element 42, which is sleeved on the rotating shaft 20. The two ends of the first elastic element 42 abut against the first limiting element 41 and the first massage component 101, respectively.

[0084] The first elastic element 42 abuts against the first limiting element 41 and the first massage component 101. When the first massage component 101 approaches the second massage component 102, the first elastic element 42, located between the first limiting element 41 and the first massage component 101, can be compressed and deformed due to the fixed position of the first limiting element 41. When the first massage component 101 moves axially towards its limit position towards the second massage component 102, the deformation generated by the first elastic element 42 is converted into a restoring force that pushes the first massage component 101 away from the second massage component 102, thereby returning the first massage component 101 to its initial position before adjustment.

[0085] The elastic component 40 also includes a second limiting member 43, which is fixed to the housing 60. The rotating shaft 20 passes through the second limiting member 43 and is movably connected to the rotating shaft 20, thereby ensuring that when the rotating shaft 20 rotates, the second limiting member 43 will not rotate with the rotating shaft 20 or move along the axial direction. At the same time, the second limiting member 43 will not hinder the rotation of the rotating shaft 20.

[0086] The elastic component 40 also includes a second elastic element 44, which is sleeved on the rotating shaft 20. The two ends of the second elastic element 44 abut against the second limiting element 43 and the second massage component 102, respectively.

[0087] Similarly, the second elastic member 44 abuts against the second limiting member 43 and the second massage assembly 102. When the second massage assembly 102 approaches the first massage assembly 101, the second elastic member 44, located between the second limiting member 43 and the second massage assembly 102, can be compressed and deformed due to the fixed position of the second limiting member 43. When the second massage assembly 102 moves axially towards its limit position towards the first massage assembly 101, the deformation generated by the second elastic member 44 is converted into a restoring force that pushes the second massage assembly 102 away from the first massage assembly 101, thereby returning the second massage assembly 102 to its initial position before adjustment.

[0088] Specifically, the first elastic element 42 and the second elastic element 44 can be springs. Using springs as the first elastic element 42 and the second elastic element 44 has the advantages of simple structure, ease of manufacturing, and maintenance. Furthermore, the spring performance can be adjusted according to specific design requirements to adapt to different working conditions. By rationally designing the relevant performance of the springs, the reset accuracy and stability of the adjusting mechanism 30 can be guaranteed, thereby improving the overall performance of the massage mechanism 100 and the user experience.

[0089] Please see Figure 3 and Figure 4 , Figure 3 This is the third schematic diagram of the structure of the massage mechanism 100 provided in the embodiments of this application. Figure 4 for Figure 3 A cross-sectional view along the AA direction. In some embodiments, the massage mechanism 100 further includes a housing 60 for accommodating the adjustment mechanism 30.

[0090] As the basic component of the massage mechanism 100, the housing 60 protects other internal components from dust, moisture, and other contaminants, thus preventing damage to the massage mechanism 100 and extending its service life. Simultaneously, the housing 60 provides support and fixation for some internal components of the massage mechanism 100.

[0091] Optionally, the housing 60 may include a first housing 601 and a second housing 602, which are detachable to facilitate the replacement and maintenance of internal components of the massage mechanism 100.

[0092] It should be noted that the first massage component 101 and the second massage component 102, the first adjustment component 31 and the second adjustment component 32 may have the same structure and working principle. The following mainly describes and introduces the first massage component 101 and the first adjustment component 31, and will not elaborate on the structure and working principle of the second massage component 102 and the second adjustment component 32.

[0093] In some embodiments, the first adjustment assembly 31 includes a base 311, which is fixed relative to the housing 60. The first adjustment assembly 31 includes an adjustment member 312, which is slidably disposed on the rotation shaft 20 and abuts against the first massage assembly 101. The adjustment member 312 is capable of slidingly engaging with the base 311.

[0094] The base 311 is fixed relative to the housing 60 to provide structural support for the sliding of the adjusting member 312, so that the adjusting member 312, which is slidably engaged with the base 311, can move away from the base 311 when the rotating shaft 20 rotates.

[0095] Furthermore, the base may include a slot 60a, which can limit the base to the housing 60 and fix it relative to the housing 60.

[0096] When the rotating shaft 20 rotates in the first direction, the rotating shaft 20 drives the adjusting member 312 to rotate. Since the base 311 is fixed to the housing 60, the base 311 can remain in a state where it does not rotate with the rotating shaft 20 and does not move. The adjusting member 312 slides relative to the base 311, thereby causing the adjusting member 312 to move away from the base 311 axially, so that the first massage component 101 moves closer to the second massage component 102.

[0097] Please see Figure 5 , Figure 5 This is an exploded view of the adjusting mechanism 30 provided in an embodiment of this application. In some embodiments, the adjusting member 312 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 adjusting member 312 and the adjusting portion 3121 when the adjusting member 312 rotates into an axial thrust to push the adjusting member 312 away from the adjusting member 312.

[0098] When the rotating shaft 20 rotates in the first direction, the rotating shaft 20 drives the adjusting member 312 to rotate synchronously. The adjusting part 3121 and the mating part 3111 slide to increase the axial distance between the adjusting member 312 and the base 311, thereby bringing the first massage assembly 101 closer to the second massage assembly 102.

[0099] When the rotating shaft 20 rotates in the second direction, the adjusting member 312 may not rotate with the rotating shaft 20. That is, when the rotating shaft 20 rotates in the second direction, the adjusting member 312 no longer pushes the adjusting member 312 to move in a direction away from the base 311.

[0100] The adjusting part 3121 and the mating part 3111 are in sliding engagement. When the adjusting part 312 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 frictional 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 adjusting part 312 to move axially, so as to drive the first massage component 101 to move axially towards the second massage component 102, thereby achieving the purpose of adjusting the distance between the first massage component 101 and the second massage component 102.

[0101] Please see Figures 6 to 9 , Figure 6 This is one of the structural schematic diagrams of the adjusting member 312 provided in the embodiments of this application. Figure 7 This is the second schematic diagram of the structure of the adjusting member 312 provided in the embodiments of this application. Figure 8 This is one of the structural schematic diagrams of the base 311 provided in the embodiments of this application. Figure 9 This is a second schematic diagram of the structure of the base 311 provided in an embodiment of this application. In some embodiments, 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 rotation shaft 20.

[0102] At least one of the adjusting part 3121 and the mating part 3111 includes a guide slope that extends spirally along the axis of rotation. 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.

[0103] 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 adjusting part 312 gradually away from the base 311. The part excluding the guide ramp can be configured as a limiting protrusion.

[0104] 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 first massage component 101 to move axially, so as to realize the adjustment between the first massage component 101 and the second massage component 102.

[0105] Please see Figure 10 , Figure 10This is a schematic diagram of the structure of the adjusting member 312 and the base 311 in accordance with the embodiments of this application. In some embodiments, both the adjusting part 3121 and the mating part 3111 include guide slopes, wherein the guide slope of the mating part 3111 is a mating slope 3116, and the guide slope of the adjusting part 3121 is an adjusting slope 3125, and the mating slope 3116 and the adjusting slope 3125 are disposed opposite to each other.

[0106] 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 first massage assembly 101 to move axially to adjust the distance between the first massage assembly 101 and the second massage assembly 102.

[0107] Meanwhile, because the user exerts a significant reaction force on the first massage component 101 during operation, this reaction force hinders the first massage component 101 and the second massage component 102 from approaching each other. Therefore, the process of separating the adjusting member 312 from the base 311 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 adjusting member 312 and the base 311 can be made more stable, thereby overcoming the significant reaction force and ensuring the reliability of the distance adjustment of the massage components.

[0108] Please see Figures 6 to 9 In some embodiments, the adjusting part 3121 includes a first limiting surface 3127 extending axially along the rotation 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 rotation shaft 20, and the second limiting surface 3115 is connected to the adjusting inclined surface 3125; when the driving member 50 drives the rotation shaft 20 to rotate in the second direction, the first limiting surface 3127 and the second limiting surface 3115 limit each other to prevent the adjusting member 312 from rotating relative to the base 311.

[0109] Specifically, when it is necessary to adjust the distance between the first massage component 101 and the second massage component 102, the drive member 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 adjusting part 312 gradually moves away from the base 311.

[0110] When no adjustment is needed, the drive member 50 can drive the rotating shaft 20 to rotate in the second direction. At this time, the adjusting member 312 does not rotate with the rotating shaft 20. Under the force of the first elastic member 42 acting on the first massage assembly 101, the adjusting slope 3125 of the adjusting part 3121 can slide along the mating slope 3116 of the mating part 3111 and move closer to the base 311 until the adjusting member 312 moves back to its initial position. At this time, the first limiting surface 3127 of the adjusting part 3121 and the second limiting surface 3115 of the mating part 3111 mutually limit each other, and the adjusting member 312 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 adjusting member 312 can move away from the base 311 again to adjust the distance between the first massage assembly 101 and the second massage assembly 102.

[0111] Please see Figures 6 to 9 In some embodiments, 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 first end face 3128 of the adjusting member 312 away from the base 311 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 second end face 3114 of the base 311 away from the adjusting member 312 gradually increases, thereby forming a plurality of positions when the adjusting member 312 rotates relative to the base 311.

[0112] Among them, the mating teeth 3112 are adapted to the adjusting teeth 3122, and the number of mating teeth 3112 is the same as the number of adjusting teeth 3122.

[0113] When the rotating shaft 20 rotates in the first direction, an adjusting tooth 3122 can slide relative to a mating tooth 3112 in the first direction and mesh with the next mating tooth 3112, thereby completing a gear adjustment. The rotating shaft 20 continues to rotate in the first direction, so that the adjusting tooth 3122 meshes with multiple mating teeth 3112 respectively, thereby completing the switching of various gears.

[0114] Furthermore, when adjusting the distance between the first massage component 101 and the second massage component 102, when the user wishes to stop adjusting the distance at a suitable target level, the angle sensor configured in the massage mechanism 100 can obtain the current rotation angle of the adjusting member 312, so that the rotating shaft 20 rotates in the second direction at a suitable rotation angle, so as to stop the adjusting member 312 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.

[0115] Meanwhile, the first elastic member 42 can apply a pushing force to the first massage component 101 that is away from the second massage component 102, thereby further ensuring that the adjusting member 312 is fixed relative to the base 311 so that the first massage component 101 no longer moves at the current setting.

[0116] It is understandable that, as the distance between the tooth tip of the mating tooth 3112 and the base 311 gradually increases, when the adjusting member 312 rotates in the first direction, one adjusting tooth 3122 can slide along the adjacent mating teeth 3112 in sequence, thereby causing the adjusting member 312 to gradually move away from the base 311.

[0117] Thus, the massager using the massage mechanism 100 can have multiple levels for selecting the distance between the first massage component 101 and the second massage component 102, and the level can be switched by rotating the rotating shaft 20 in the first direction, so that the massager can adapt to users of various body types, thereby improving the user experience.

[0118] Please see Figures 6 to 9 In some embodiments, 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 height of two adjacent adjusting teeth 3122 is the same. In addition, 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 height of two adjacent mating teeth 3112 is the same.

[0119] 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.

[0120] In this way, the adjustment tooth heights of two adjacent adjustment teeth 3122 are the same, ensuring that the adjustment amount of each gear is equal when adjusting the distance between the first massage component 101 and the second massage component 102, so that the user can obtain a stable and predictable adjustment effect, thereby improving the efficiency of the adjustment.

[0121] In some embodiments, the pitch-adjusting tooth surface 3123 has an inclination angle relative to the axial direction of the rotating shaft 20, the inclination angle θ satisfying: 3°≤θ≤45°; and / or the axial distance L between the two ends of the pitch-adjusting inclined surface 3125 satisfies 2mm≤L≤20mm.

[0122] 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 difficulty in the movement of the adjusting component 312 relative to the base 311, 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°.

[0123] Specifically, the tilt angle θ of the adjusting tooth surface 3123 relative to the axis of the rotating shaft 20 can be 3°, 10°, 20°, 30° or 45°.

[0124] Meanwhile, the adjustable range of the first massage component 101 is limited to 2mm≤L≤20mm. This range can adapt to the body shape of most users, so that the massage mechanism 100 can meet the usage needs of most customers.

[0125] Specifically, the axial distance L between the two ends of the adjustable inclined plane 3125 can be 2mm, 3mm, 9mm, 10mm, or 20mm.

[0126] In addition, the adjustable range of the first massage component 101 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 too large or too small at one time, so as to ensure the efficiency of the user when adjusting the first massage component 101 and the second massage component 102.

[0127] Please see Figures 6 to 9 In some embodiments, the first limiting surface 3127 is connected to the adjusting tooth surface 3123 of the first adjusting tooth 3122a, and the first adjusting tooth 3122a is the adjusting tooth 3122 with the largest distance from the first end face 3128. The second limiting surface 3115 is connected to the mating tooth surface 3113 of the first mating tooth 3112a, and the first mating tooth 3112a is the mating tooth 3112 with the largest distance from the second end face 3114.

[0128] It can be understood that the first adjusting tooth 3122a 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 3122a. That is, the first limiting surface 3127 limits the final position of the adjusting member 312 relative to the base 311 for multi-position adjustment.

[0129] Furthermore, the second adjusting tooth 3122b is the adjusting tooth 3122 with the smallest distance from the first end face 3128, and the second mating tooth 3112b is the mating tooth 3112 with the smallest distance from the second end face 3114.

[0130] As the first adjusting tooth 3122a slides sequentially from the second mating tooth 3112b to the first mating tooth 3112a, the distance between the adjusting member 312 and the base 311 gradually increases. Since the mating tooth surface 3113 of the first mating tooth 3112a is connected to the second limiting surface 3115, when the rotating shaft 20 continues to rotate in the first direction, the distance between the adjusting member 312 and the base 311 is at its farthest when the first adjusting tooth 3122a abuts against the connection between the first mating tooth 3112a and the second limiting surface 3115. The adjusting member 312 reaches the limit position of the adjusting distance, which is also the maximum adjusting position of the adjusting mechanism 30. If the rotating shaft 20 continues to rotate in the first direction, the first adjusting tooth 3122a will fall off the first mating tooth 3112a, the adjusting member 312 will move close to the base 311 and move back to the initial position, returning to the position with the furthest distance between the first massage component 101 and the second massage component 102, and then the distance between the two massage components can be readjusted according to the user's needs.

[0131] In some embodiments, when the rotating shaft 20 rotates in the first direction, the adjusting member 312 rotates synchronously with the rotating shaft 20. The adjusting teeth 3122 on the adjusting member 312 slide and engage with a plurality of mating teeth 3112 on the base 311 in sequence. The adjusting teeth 3122 engage with different mating teeth 3112 to complete the switching between different gears, thereby causing the adjusting member 312 to move away from the base 311 along the axial direction according to different gears.

[0132] When the rotating shaft 20 rotates in the second direction, if the adjusting member 312 is stationary relative to the base 311 during the adjusting process of the adjusting member 312, the adjusting tooth 3122 engages with a mating tooth 3112, so that the adjusting member 312 and the base 311 will not rotate relative to each other. That is, the adjusting tooth 3122 engages with a mating tooth 3112 and will not switch to another mating tooth 3112, thereby ensuring that the relative position of the adjusting member 312 and the base 311 is fixed, and also ensuring that the distance between the first massage component 101 and the second massage component 102 is fixed.

[0133] When the rotating shaft 20 rotates in the second direction, if the adjusting member 312 is not in the adjusting state, the adjusting member 312 is stationary relative to the base 311, and the first limiting surface 3127 and the second limiting surface 3115 limit each other, so that the adjusting member 312 and the base 311 will not rotate relative to each other. The driving member 50 will drive the first massage assembly 101 and the second massage assembly 102 to perform massage operations. Please refer to Figures 6 to 9 In some embodiments, the base 311 includes two mating portions 3111, and the two mating portions 3111 are symmetrically arranged with respect to the axis of the rotation shaft 20. The adjusting member 312 includes two adjusting portions 3121, and the two adjusting portions 3121 are symmetrically arranged with respect to the axis of the rotation shaft 20.

[0134] 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 adjusting part 312 and the base 311, and make the external force on the two mating parts 3111 and the two adjusting parts 3121 evenly distributed. This prevents the adjusting part 312 from tilting to one side due to uneven force, which would affect the adjusting effect or even cause the adjusting part 312 to jam.

[0135] 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 adjusting part 312 to fall back to its initial position from the base 311 after being adjusted to the position closest to the first massage component 101 and the second massage component 102. That is, the position where the adjusting part is close to the base 311. 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.

[0136] 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 mechanism 30.

[0137] Please see Figure 6 and Figure 7 In some embodiments, the adjusting member 312 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 outward along the axial direction of the rotation shaft 20 to the adjusting portion 3121, and the mating portion 3111 can be sleeved on the support portion 3129.

[0138] The mating part 3111 of the base 311 can surround the support part 3129 of the adjusting member 312, so that the mating part 3111 can also limit the adjusting member 312 in the radial direction of the rotating shaft 20 and the base 311, so as to avoid excessive radial offset of the adjusting member 312 and wear between the adjusting member 312 and the rotating shaft 20.

[0139] Meanwhile, the fitting part 3111 is sleeved on the support part 3129 so that the support part 3129 can support the fitting part 3111 and prevent the fitting part 3111 from shaking under the influence of external forces.

[0140] Please see the return Figure 5 In some embodiments, the massage mechanism 100 further includes a clutch 70 disposed between the rotating shaft 20 and the adjusting member 312. The clutch 70 can drive the adjusting member 312 to rotate synchronously with the rotating shaft 20 when the rotating shaft 20 rotates in a first direction, and can keep the adjusting member 312 stationary when the rotating shaft 20 rotates in a second direction.

[0141] When the rotating shaft 20 rotates in the first direction, it drives the clutch 70 to rotate, thereby causing the clutch 70 to drive the adjusting member 312 to move. The adjusting member 312 adjusts the distance between the first massage assembly 101 and the second massage assembly 102. When the rotating shaft 20 rotates in the second direction, it rotates in the second direction but does not drive the clutch 70 to rotate, thereby preventing the adjusting member 312 from moving and thus preventing the adjusting member 312 from adjusting the distance between the first massage assembly 101 and the second massage assembly 102.

[0142] It is understood that when adjusting the distance between the first massage component 101 and the second massage component 102, the rotating shaft 20 rotates in the first direction. At this time, the rotating shaft 20 drives the adjusting component 312 to adjust the distance and causes the first massage component 101 to swing and massage. When the first massage component 101 and the second massage component 102 do not need to be adjusted, the rotating shaft 20 rotates in the second direction. At this time, the user does not have a need to adjust the distance of the massage components, and the massage components can meet the user's massage needs simply by performing kneading movements.

[0143] The clutch 70 ensures that the distance between the first massage component 101 and the second massage component 102 does not change during the massage process when the rotating shaft 20 rotates in the second direction, thus ensuring the stability of the distance between the first massage component 101 and the second massage component 102 and improving the stability of the massage process.

[0144] In some embodiments, the clutch 70 includes a one-way bearing, which is sleeved on the rotating shaft 20, and the adjusting member 312 is sleeved on the rotating shaft 20 via the one-way bearing.

[0145] Using a one-way bearing enables the engagement and disengagement of the adjusting element 312 and the rotating shaft 20, allowing the adjusting element 312 to move only when the rotating shaft 20 rotates in the first direction. The one-way bearing has a simple structure, which helps to make reasonable use of the internal space of the massage mechanism 100, thus enabling the massage mechanism 100 to be miniaturized.

[0146] Please see Figure 5 In some embodiments, the massage mechanism 100 further includes a metal sleeve 701, which is sleeved on the outside of the rotating shaft 20 and located between the clutch 70 and the rotating shaft 20.

[0147] The metal sleeve 701 effectively prevents the clutch 70 from shifting away from the rotating shaft 20 when subjected to external force. During the use of the massager, especially when the user applies pressure or makes dynamic adjustments, shifting of the clutch 70 may cause changes in the adjusted massage interval, thereby affecting the massage effect and user experience.

[0148] Secondly, the use of the metal sleeve 701 also helps to achieve the goal of miniaturization of the massager. The metal sleeve 701 allows the clutch 70 and the rotating shaft 20 to adopt a more compact design.

[0149] Please see Figure 11 , Figure 11 This is the fourth schematic diagram of the structure of the massage mechanism 100 provided in the embodiments of this application. In some embodiments, the massage mechanism 100 further includes a gear set 801, which is connected to the output shaft of the drive member 50, and the output shaft of the drive member 50 is perpendicular to the axial direction of the rotating shaft 20; and a bevel gear assembly 802, which is sleeved on the rotating shaft 20 and is connected to the gear set 801.

[0150] The drive component 50 is connected to the gear set 801 via an output shaft. The rotation of the output shaft of the drive component 50 drives the gear set 801 to rotate, which in turn drives the bevel gear assembly 802 to rotate. The output shaft of the drive component 50 is perpendicular to the axis of the rotating shaft 20. The bevel gear assembly 802 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 to drive the rotating shaft 20.

[0151] Optionally, the gear set 801 may include a first transmission gear and a second transmission gear.
