Description

Technical Field

[0001] This disclosure relates to the field of health care device technology, and in particular to a protective device and a massage device. Background Technology

[0002] Massage devices, as health care instruments to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are usually designed according to the structural characteristics of different parts of the human body, such as neck massage devices, waist massage devices, and dual-area massage devices.

[0003] In related technologies, some massage devices feature adjustable massage heads to accommodate the massage needs of people with different body types. However, these devices require the integration of more motion structures, some of which need to be protected by a housing assembly. Since the housing assembly also needs to avoid obstructing other motion structures, its overall size is relatively large, hindering the miniaturization of the massage device. Summary of the Invention

[0004] This disclosure provides a protective device and a massage device. The protective device integrates some moving parts and has a compact structure and small size, which is beneficial for the miniaturization of the massage device.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a protective device is provided, including a first housing assembly and a second housing assembly. The first housing assembly and the second housing assembly cooperate to form a first protective cavity, and the second housing assembly is rotatably connected to the first housing assembly. One of the first housing assembly and the second housing assembly is provided with a limiting structure, and the other is provided with a control structure. The control structure cooperates with the limiting structure to control the rotation or fixation of the second housing assembly relative to the first housing assembly.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the limiting structure includes an internal gear, and the control structure includes a control gear set that meshes with the internal gear. The control gear set drives the internal gear to rotate, thereby driving the second housing assembly to rotate relative to the first housing assembly.

[0012] In one embodiment, the internal gear has a receiving cavity, and a driving gear and at least one driven gear are disposed within the receiving cavity. The gear carrier includes a plate that shields the receiving cavity. The first housing assembly also includes a first cover for shielding the receiving cavity. The first cover and the plate are spaced apart along the rotation axis of the driving gear to shield the receiving cavity.

[0013] And / or, the drive unit includes a worm gear, a turbine gear that engages with the drive gear, and a motor fixed to the second housing assembly. The output shaft of the motor is fixedly connected to the worm gear, and the turbine gear engages with the worm gear drive.

[0014] In one embodiment, the drive gear has a shaft connected to the turbine drive, and the first cover has a clearance hole for the shaft to pass through.

[0015] And / or, the first cover and the second housing assembly cooperate to form a second protective cavity for accommodating the worm and the turbine.

[0016] In one embodiment, the second housing assembly includes a second housing, a third housing, and a fourth housing. The second and third housings are fixedly connected to form a first protective cavity. The third housing is fixedly connected to an internal gear to allow a receiving cavity to communicate with the first protective cavity. The fourth housing is fixedly connected to the internal gear and cooperates with a first cover to form a second protective cavity.

[0017] In one embodiment, the internal gear is fixed to the second housing assembly and forms a receiving cavity; the control gear set is rotatably disposed within the receiving cavity.

[0018] In one embodiment, the limiting structure includes a first limiting portion disposed on the second housing assembly, and the control structure includes a control member movably disposed on the first housing assembly, the control member having a second limiting portion.

[0019] When the control component is in the limit state, the second limit part cooperates with the first limit part to limit and fix the first housing assembly and the second housing assembly relative to each other.

[0020] When the control element is in the released state, the second limiting part separates from the first limiting part, so that the second housing assembly can rotate relative to the first housing assembly.

[0021] In one embodiment, the first limiting part includes a limiting tooth, and the second limiting part includes a mating tooth that meshes with the limiting tooth.

[0022] And / or, the control element is swayably mounted on the first housing assembly, and one end of the control element is provided with a second limiting part, and the other end is provided with a locking part. The first housing assembly is provided with an elastic buckle part, which engages with the locking part to lock the control element in the limited position.

[0023] In one embodiment, the first housing assembly has a first receiving groove, and the second housing assembly has a second receiving groove that cooperates with the first receiving groove to form a first protective cavity.

[0024] And / or, the protective assembly also includes a retractable elastic shield fixed between the first housing assembly and the second housing assembly for shielding the first protective cavity.

[0025] According to a third aspect of the present disclosure, a massage device is also provided, including a first support component, a second support component, a first massage component movably disposed on the first support component, a second massage component movably disposed on the second support component, a power mechanism for driving the first massage component and the second massage component to move, and a protective device as described in the above embodiments. The first support component is fixedly connected to a first housing component, and the second support component is fixedly connected to a second housing component. At least a portion of the power mechanism is disposed within a first protective cavity.

[0026] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0027] When in use, the massage device has a first support component fixedly connected to a first housing component, and a second support component fixedly connected to a second housing component. The first and second housing components can then rotate relative to each other, making the angle between them adjustable. The first support component has a first massage component, and the second support component has a second massage component, thus making the massage range of both components adjustable.

[0028] This protective device integrates a limiting structure and a control structure onto the first and second housing assemblies, respectively. The control structure cooperates with the limiting structure to control the rotation or fixation of the second housing assembly relative to the first housing assembly. Simultaneously, the first and second housing assemblies form a first protective cavity to protect at least a portion of the power mechanism, improving its protective performance without affecting the adjustment of the massage range of the massage assembly. Thus, this protective device integrates a portion of the moving structure, resulting in a compact structure and small size, which is beneficial for the miniaturization of massage devices.

[0044] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0046] Massage devices, as health care tools to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and so on. Currently, there are numerous types and brands of massage devices available, giving consumers a wide range of choices. Therefore, how to win consumer favor and enhance product competitiveness has become an increasingly important issue for massage device manufacturers.

[0047] Currently, with the increasing prevalence of sedentary work and lifestyles, people are prone to neck and / or shoulder discomfort, leading to a growing market demand for massage devices that can massage these areas. For example, a shoulder and neck massager is specifically designed for the curves of the shoulder and neck. It uses shoulder massagers to massage and relax shoulder muscles, effectively relieving shoulder muscle fatigue. Simultaneously, it uses neck massagers to massage and relax neck muscles, effectively relieving neck muscle fatigue.

[0048] In related technologies, some massage devices feature adjustable massage heads to accommodate the massage needs of people with different body types. For example, in addition to the power source driving the massage components, a spacing adjustment mechanism is needed to adjust the distance between two sets of massage components, and / or an angle adjustment mechanism is used to adjust the massage range of the massage components to accommodate different massage areas or the massage needs of different body types for the same area. In this case, such massage devices need to integrate more motion structures (such as lead screw and nut mechanisms, gear and rack mechanisms, etc.), and some of these motion structures require protection by a housing assembly. Since the housing assembly also needs to avoid other motion structures, this results in a relatively large overall size, which is detrimental to the miniaturization of the massage device.

[0049] Based on this, the present disclosure provides a protective device. This protective device can integrate some moving structures, and has a compact structure and small size, which is beneficial for the miniaturization of massage devices.

[0050] To better understand the protective device of this disclosure, the following description uses a massage device incorporating the protective device.

[0051] like Figures 1 to 5 The diagram shows a structural view of the massage device and its protective mechanism. Among them, Figure 1 This is a schematic diagram of the structure of a massage device shown in one embodiment. Figure 2 for Figure 1 The diagram shows the structure of the protective device. Figure 3 for Figure 2 The diagram shows the structure of the protective device from a downward viewing angle. Figure 4 for Figure 2 A top view of the protective device shown. Figure 5 for Figure 4 The diagram shows a half-section of AA.

[0052] like Figure 1 As shown, in some embodiments, a massage device 10 is provided, including a protective device 100, a first support component 200, a second support component 300, a first massage component 400 movably disposed on the first support component 200, a second massage component 500 movably disposed on the second support component 300, and a power mechanism 600 for driving the first massage component 400 and the second massage component 500 to move.

[0053] Among them, such as Figures 2 to 5 As shown, the protective device 100 includes a first housing assembly 110 fixedly connected to the first support assembly 200 and a second housing assembly 120 fixedly connected to the second support assembly 300. The first housing assembly 110 and the second housing assembly 120 cooperate to form a first protective cavity 101, and the second housing assembly 120 is rotatably connected to the first housing assembly 110. At least a portion of the power mechanism 600 is disposed within the first protective cavity 101. One of the first housing assembly 110 and the second housing assembly 120 is provided with a limiting structure 130, and the other is provided with a control structure 140. The control structure 140 cooperates with the limiting structure 130 to control the rotation or fixation of the second housing assembly 120 relative to the first housing assembly 110.

[0054] When the massage device 10 is in use, the first support component 200 is fixedly connected to the first housing component 110, and the second support component 300 is fixedly connected to the second housing component 120. The first housing component 110 and the second housing component 120 can then rotate relative to each other, making the angle between the first support component 200 and the second support component 300 adjustable. The first support component 200 is provided with a first massage component 400, and the second support component 300 is provided with a second massage component 500, thus making the massage range of the first massage component 400 and the second massage component 500 adjustable.

[0055] The protective device 100 integrates the limiting structure 130 and the control structure 140 onto the first housing assembly 110 and the second housing assembly 120, respectively. The control structure 140 cooperates with the limiting structure 130 to control the rotation or fixation of the second housing assembly 120 relative to the first housing assembly 110. Simultaneously, the first housing assembly 110 and the second housing assembly 120 can form a first protective cavity 101 to protect at least a portion of the power mechanism 600, improving the protective performance of the power mechanism 600 without affecting the adjustment of the massage range of the massage assembly. Thus, the protective device 100 integrates a portion of the moving structure, has a compact structure, and a small size, which is beneficial for the miniaturization of the massage device 10.

[0056] Understandably, the change in the swing angle of the first housing assembly 110 and the second housing assembly 120 causes changes in the angle and distance between the first massage assembly 400 and the second massage assembly 500, thereby changing the massage range of the first massage assembly 400 and the second massage assembly 500, enabling different massage needs to be met. Compared with conventional technology, integrating the limiting structure 130 and the control structure 140 onto the first housing assembly 110 and the second housing assembly 120 respectively to adjust the massage range of the massage assemblies effectively reduces motion interference, making the protective device 100 more compact and smaller in size. This also makes the massage device 10 more compact and smaller in size, which is beneficial for the miniaturization of the massage device 10.

[0057] It should be noted that there are multiple ways to implement the first housing assembly 110 and / or the second housing assembly 120, including forming it using only one housing, splicing it together from multiple housings, or splicing it together from multiple components.

[0058] It should be noted that the specific implementation of the power mechanism 600 can be in various ways, including but not limited to a rotary power source + flexible transmission mechanism (e.g., pulley mechanism, chain mechanism, etc.), a rotary power source + gear transmission mechanism (e.g., multi-gear mechanism, etc.), a rotary power source + linkage mechanism (e.g., double swing mechanism, cam mechanism, etc.), a telescopic power mechanism 600, etc., which can drive the first massage component 400 and the second massage component 500 to move synchronously.

[0059] In some embodiments, the power mechanism 600 includes a power source, a power shaft driven by the power source, a driving member disposed on the power shaft, a first driven member for driving the first massage component to move, and a second driven member for driving the second massage component to move. The driving member drives the first and second driven members to rotate. Thus, the power source drives the power shaft to rotate, which in turn drives the driving member to rotate, and the driving member drives the first and second driven members to rotate synchronously, thereby driving the first and second massage components to rotate.

[0060] It should be noted that the driving component and the driven component can be connected by transmission mechanisms such as gear transmission mechanisms and flexible transmission mechanisms.

[0061] In some embodiments, the first protective cavity 101 can at least protect the power shaft and the active component disposed on the power shaft. In this way, damage to the power shaft and / or active component caused by the ingress of foreign objects can be reduced, thereby improving the protective performance of the massage device 10 and enhancing the durability of the massage device 10.

[0062] Furthermore, there are various ways to implement the first housing assembly 110 and the second housing assembly 120 in cooperation to form the first protective cavity 101, including but not limited to one of the first housing assembly 110 and / or the second housing assembly 120 having a receiving groove.

[0063] like Figure 3 As shown, in some embodiments, the first housing assembly 110 is provided with a first receiving groove 111, and the second housing assembly 120 is provided with a second receiving groove 121 that cooperates with the first receiving groove 111 to form a first protective cavity 101. In this way, the first protective cavity 101 is easily formed by the cooperation of the first receiving groove 111 and the second receiving groove 121.

[0064] Furthermore, the arrangement of the first receiving groove 111 and the second receiving groove 121 allows the parts of the first housing assembly 110 and the second housing assembly 120 to be nested together without interfering with their rotation, and also ensures the protective space of the first protective cavity 101, thereby improving the protective performance of the massage device 10.

[0065] It should be noted that there are various ways to implement the limiting structure 130 and the control structure 140, including but not limited to the limiting cooperation of the convex and concave parts, the locking cooperation, etc., as long as they can control the rotation or fixation of the second housing assembly 120.

[0066] like Figure 4 as well as Figure 5 As shown, in some embodiments, the limiting structure 130 includes an internal gear 131, and the control structure 140 includes a control gear set 141 that meshes with the internal gear 131. The control gear set 141 drives the internal gear 131 to rotate, thereby driving the second housing assembly 120 to rotate relative to the first housing assembly 110. When the control gear set 141 stops rotating, the second housing assembly 120 and the first housing assembly 110 are fixed relative to each other. Thus, through the cooperation between the internal gear 131 and the control gear set 141, the rotation or stopping of the internal gear 131 can be easily controlled, thereby causing the second housing assembly 120 to rotate or be fixed.

[0067] Furthermore, it is understood that the control gear set 141 can be driven or stopped manually or electrically to control the rotation or stop the rotation of the internal gear 131.

[0068] like Figure 5 as well as Figure 6 As shown, in some embodiments, the internal gear 131 is fixed to the second housing assembly 120 and forms a receiving cavity 1311. The control gear set 141 is rotatably disposed within the receiving cavity 1311. Thus, by using the receiving cavity 1311 of the internal gear 131 to accommodate the control gear set 141, the limiting structure 130 and the control structure 140 are tightly fitted, which is beneficial for reducing the size of the protective device 100 and for miniaturizing the massage device 10.

[0069] like Figures 5 to 7 As shown, in some embodiments, the internal gear 131 is fixed to the second housing assembly 120, and the control gear set 141 is rotatably disposed on the first housing assembly 110. The protective device 100 also includes a drive unit 150, which is disposed on the second housing assembly 120 and is used to drive the control gear set 141 to rotate. Thus, when the drive unit 150 starts to output power, the internal gear 131 can be driven to rotate by the control gear set 141, thereby realizing the rotation between the second housing assembly 120 and the first housing assembly 110, and realizing the adjustment of the distance and angle between the first massage assembly 400 and the second massage assembly 500.

[0070] Furthermore, the internal gear 131 is fixed to the second housing assembly 120, and the control gear set 141 is rotatably disposed on the first housing assembly 110. This facilitates assembly and reduces assembly difficulty.

[0071] like Figure 5 as well as Figure 6 As shown, in some embodiments, the first housing assembly 110 includes a first housing 112 that cooperates with the second housing assembly 120 to form a first protective cavity 101, and a gear carrier 113 fixed to the first housing 112. The control gear set 141 is rotatably disposed on the gear carrier 113. Thus, by assembling the first housing assembly 110 with the gear carrier 113 and the first housing 112, the manufacturing difficulty of the first housing assembly 110 can be effectively reduced. Furthermore, the use of the gear carrier 113 facilitates assembly with the control gear set 141, thereby improving assembly efficiency.

[0072] It should be noted that the specific number of gears in the control gear set 141 can be selected according to actual needs, as long as it can drive the internal gear 131 to rotate.

[0073] like Figure 5 as well as Figure 6As shown, in some embodiments, the control gear set 141 includes a drive gear 1411 and at least one driven gear 1412 meshing with the drive gear 1411. The drive gear 1411 is rotatably mounted on the gear carrier 113. At least one driven gear 1412 is rotatably mounted on the gear carrier 113 and meshes with an internal gear 131. The drive unit 150 is used to drive the drive gear 1411 to rotate. Thus, when it is necessary to adjust the massage range of the first massage assembly 400 and the second massage assembly 500, the drive unit 150 drives the drive gear 1411 to rotate, and the drive gear 1411 drives the internal gear 131 to rotate through the driven gear 1412, thereby driving the second housing assembly 120 to rotate relative to the first housing assembly 110. When it is necessary to fix the massage range of the first massage component 400 and the second massage component 500, the drive unit 150 stops outputting power, thereby fixing the drive gear 1411, which in turn limits the rotation of the driven gear 1412, fixing the inner gear 131, and thus fixing the first housing component 110 and the second housing component 120 relative to each other.

[0074] It should be noted that the specific structure of the gear carrier 113 can vary, as long as it can support the control gear set 141. For example, the gear carrier 113 includes a connecting shaft 1132 that rotatably engages with the control gear set 141.

[0075] like Figure 5 as well as Figure 6 As shown, in some embodiments, the internal gear 131 has a receiving cavity 1311, the driving gear 1411 and at least one driven gear 1412 are disposed within the receiving cavity 1311, and the gear carrier 113 includes a plate 1131 that shields the receiving cavity 1311. The first housing assembly 110 also includes a first cover 114 for shielding the receiving cavity 1311. The first cover 114 and the plate 1131 are spaced apart along the rotation axis of the driving gear 1411 to shield the receiving cavity 1311. Thus, by placing the driving gear 1411 and at least one driven gear 1412 within the receiving cavity 1311 of the internal gear 131, and by using the cooperation of the plate 1131 and the first cover 114 to shield the receiving cavity 1311, foreign objects can be prevented from entering between the driving gear 1411 and the driven gear 1412, and / or between the driven gear 1412 and the driving gear 1411, causing gear jamming or gear damage, thereby improving the reliability of the massage range adjustment of the massage assembly.

[0076] Understandably, the plate 1131 and the first cover 114 are used to shield the receiving cavity 1311, so as to facilitate the storage of lubricant to lubricate the control gear set 141.

[0077] Optionally, in some embodiments, the gear carrier 113 further includes a plurality of connecting shafts 1132 fixed to the plate 1131, at least one connecting shaft 1132 being rotatably connected to the driving gear, and the driven gear 1412 corresponding to the other connecting shafts 1132 one by one and being rotatably connected.

[0078] It should be noted that the drive unit 150 can be implemented in various ways, including but not limited to using a rotary power source to directly or intermittently drive the control gear set 141 to rotate, or using a linear power source + linear-to-rotary transmission mechanism to drive the control gear set 141 to rotate (for example, a linear motor + gear and rack assembly to drive the control gear set 141 to rotate).

[0079] like Figure 7 As shown, in some embodiments, the drive unit 150 includes a turbine 151 and a worm gear 152 that are driven by the drive gear 1411, and a motor 153 fixed to the second housing assembly 120. The output shaft of the motor 153 is fixedly connected to the worm gear 152, and the turbine 154 is driven by the worm gear 151. In this way, the motor 153 drives the turbine 151 to rotate through the worm gear 152, and drives the drive gear 1411 to rotate through the turbine 151. This allows the spacing between the motor 153 and the drive gear 1411 to be flexibly set, reducing the difficulty of arranging the drive unit 150 and the drive gear 1411.

[0080] Optional, see you later Figure 5 As shown, in some embodiments, the drive gear 1411 is provided with a shaft 1001 that is drively connected to the turbine 151, and the first cover 114 is provided with a clearance hole for the shaft 1001 to pass through. In this way, when the shaft 1001 is integrated into the drive gear 1411 and the first cover 114 covers the receiving cavity 1311, the shaft 1001 passes through the clearance hole to facilitate drive connection with the turbine 151, thereby realizing the drive connection between the drive gear 1411 and the turbine, which can reduce the assembly difficulty.

[0081] Optionally, such as Figure 5 As shown, in some embodiments, the first cover 114 cooperates with the second housing assembly 120 to form a second protective cavity 102 to accommodate the worm gear 152 and the turbine 151. Thus, the second protective cavity 102 protects the turbine 151 and the worm gear 152, facilitates lubrication of the turbine 151 and the worm gear 152, and prevents foreign objects from entering between the turbine 151 and the worm gear 152, causing jamming, thereby improving the reliability of the drive unit 150.

[0082] like Figure 5As shown, in some embodiments, the second housing assembly 120 includes a second housing 122, a third housing 123, and a fourth housing 124. The second housing 122 and the third housing 123 are fixedly connected to form a first protective cavity 101. The third housing 123 is fixedly connected to an internal gear 131 so that the receiving cavity 1311 communicates with the first protective cavity 101. The fourth housing 124 is fixedly connected to the internal gear 131 and cooperates with the first cover 114 to form a second protective cavity 102. Thus, by assembling the second housing assembly 120 using the second housing 122, the third housing 123, and the fourth housing 124, the manufacturing difficulty of the second housing assembly 120 can be reduced. It is also convenient to cooperate with the first housing assembly 110 to form the first protective cavity 101, the receiving cavity 1311, and the second protective cavity 102. At least a portion of the power mechanism 600, the control gear set 141, and the drive unit 150 are integrated together, making the massage device 10 more compact and facilitating miniaturization.

[0083] like Figure 8 As shown, in other embodiments, the limiting structure 130 includes a first limiting portion 132 disposed on the second housing assembly 120, and the control structure 140 includes a control member 143 movably disposed on the first housing assembly 110, the control member 143 having a second limiting portion 1431. When the control member 143 is in the limiting state, the second limiting portion 1431 engages with the first limiting portion 132 to limit and fix the first housing assembly 110 and the second housing assembly 120 relative to each other. When the control member 143 is in the releasing state, the second limiting portion 1431 separates from the first limiting portion 132, allowing the second housing assembly 120 to rotate relative to the first housing assembly 110. Thus, by manually operating the control member 143, the control member 143 can be switched between the limiting state and the releasing state, making it easy to control the second housing assembly 120.

[0084] It should be noted that the first limiting part 132 and the second limiting part 1431 can be implemented in various ways. For example, the first limiting part 132 may include multiple limiting holes, and the second limiting part 1431 may include a limiting protrusion that engages with the limiting holes. Alternatively, the first limiting part 132 may include multiple limiting protrusions, and the second limiting part 1431 may include a limiting hole that engages with the limiting holes. Alternatively, the first limiting hole may include multiple locking parts, and the second limiting part 1431 may include a locking tongue that engages with the locking parts.

[0085] Optionally, in some embodiments, the first limiting portion 132 includes a limiting tooth, and the second limiting portion 1431 includes a mating tooth that meshes with the limiting tooth. Thus, when the control member 143 is in the limiting state, the engagement of the mating tooth and the limiting tooth securely fixes the first housing assembly 110 and the second housing assembly 120 relative to each other. The limiting tooth and the mating tooth are easily separable, facilitating the control member 143 to switch from the limiting state to the released state, or vice versa.

[0086] like Figure 8 As shown, in some embodiments, the control member 143 is swayably mounted on the first housing assembly 110, and one end of the control member 143 is provided with a second limiting part 1431, and the other end is provided with a locking part 1432. The first housing assembly 110 is provided with an elastic buckle 114, which engages with the locking part 1432 to lock the control member 143 in a limited state. Thus, when the elastic buckle 114 engages with the locking part 1432, the control member 143 is reliably locked in the limited state, so that the second housing assembly 120 and the first housing assembly 110 are securely fixed. When the elastic buckle 114 deforms, the locking part 1432 is easily released, allowing the control member 143 to switch to the released state.

[0087] like Figure 9 As shown, in some embodiments, the protective assembly 100 further includes a retractable elastic shielding member 160 fixed between the first housing assembly 110 and the second housing assembly 120, the elastic shielding member 160 being used to shield the first protective cavity 101. Thus, the elastic shielding member 160 can shield the first protective cavity without affecting the relative rotation of the second housing assembly.

[0088] Optionally, the resilient shield 160 includes multiple bending structures to avoid interfering with the relative rotation of the second housing assembly and the first housing assembly.

[0089] Optionally, the material of the elastic shielding element 160 may include silicone, rubber, elastic fabric, etc.

[0090] It should be noted that the first massage component and the second massage component can be implemented in various ways, and can be moved to achieve at least one of pressing, pinching, kneading, etc.

[0091] The first and second massage components can be used to massage at least one of the following parts of the human body: neck, shoulders, back, waist, thighs, etc.

[0092] Optionally, in some embodiments, the first and second massage components can massage two areas, such as the neck and shoulders. For example, both the first and second massage components have a neck massage head and a shoulder massage head, enabling them to massage the neck and shoulders of the human body respectively.

[0093] It should be noted that "adjustment of the massage range of the first massage component and the second massage component" should be interpreted broadly, including changes in the massage trajectory of the first massage component and the second massage component, as well as changes relative to the user's body.

[0094] Combination Figure 10 As shown, when the massage device 10 is used for shoulder and neck massage, the adjustment of the massage range of the first massage component 400 and the second massage component 500 allows for adjustment of the distance between the first massage component 400 and the second massage component 500 and the human spine, and / or the vertical adjustment of the neck, and / or the vertical adjustment of the shoulders. For example, when a user uses the massage device 10 for massage, if they find that the massage position of the first massage component 400 and / or the second massage component 500 is far from the spine, while the uncomfortable area that needs massage is close to the spine, then the angle between the first housing component and the second housing component can be reduced by the cooperation of the limiting structure and the control structure, so that the first massage component 400 and the second massage component 500 move closer to the spine, thereby enabling massage of the uncomfortable area of ​​the human body.

[0095] The terms "first," "second," etc., used in the description of this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0096] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0097] It should be noted that when a component is described as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "transmittingly connected" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved. Methods such as socketing, snap-fitting, integral molding, and welding are feasible in traditional technologies and will not be elaborated upon here.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
