Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a massage device capable of performing asynchronous massage. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, massage devices are being used more and more widely in daily life. As a common health care device, massage devices are widely used in homes, medical facilities, and rehabilitation centers to relieve muscle fatigue, promote blood circulation, and improve physical comfort. Furthermore, due to... Traditional massage devices typically employ synchronous massage, where all massage units move at the same frequency and phase. Due to the lack of phase difference, synchronous massage results in relatively monotonous massage movements. While this monotonous massage method can alleviate muscle fatigue to some extent, its effectiveness is limited for different muscle groups and varying massage needs. For example, synchronous massage may not effectively simulate the complex techniques of manual massage, such as kneading and pushing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a massage device that can perform asynchronous massage. By introducing a phase change structure into the rotating device of the massage device, a phase difference can be generated between the two massage units, thereby realizing asynchronous massage.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A massage device capable of asynchronous massage includes a housing, two massage units arranged at intervals, and two rotating devices for respectively driving the massage units; at least one of the two rotating devices is configured as a phase-changing structure, the rotating device including a first turntable and a first rotating shaft, the phase-changing structure including: A first pin is fixed to the first rotating shaft and configured to rotate with the first rotating shaft; Two first stop portions are arranged circumferentially at intervals on the first rotating shaft; and The clearance space formed between the two first stops; The first pin has a first transmission end protruding from the outer circumference of the first rotating shaft. The first transmission end is adapted to press against one of the two first stop portions to transmit rotational power. When the first rotating shaft changes its rotation direction, the first transmission end disengages from one of the first stop portions and then presses against the other first stop portion after passing through the clearance space, so that a phase difference is generated between the two rotating devices to execute an asynchronous massage mode.

[0005] Furthermore, the asynchronous massage mode refers to the two massage units alternately performing massage actions with different rhythms, directions, or movements, forming a complementary or alternating massage mode.

[0006] Furthermore, when the phase difference between the two rotating devices is zero, a synchronous massage mode is executed between the two rotating devices. The synchronous massage mode refers to a massage mode in which the two massage units simultaneously perform massage actions with the same rhythm, direction, and movement.

[0007] Furthermore, the first transmission end is defined as being in a first position when it presses against one of the two first stops, and is positioned as a second position when it presses against the other of the two first stops. The first transmission end switches between the synchronous massage mode and the asynchronous massage mode when it moves between the first position and the second position.

[0008] Furthermore, the first transmission end is arranged to protrude outward along the radial direction of the first rotating shaft.

[0009] Furthermore, the clearance space allows the first pin to rotate at an angle of 30°-270°.

[0010] Furthermore, the other of the two rotating devices is configured as a phase-holding structure, which includes a second turntable and a second shaft, the second turntable and the second shaft being fixedly connected to form a phase-holding structure capable of restricting relative rotation between them.

[0011] Furthermore, the phase-preserving structure includes: Two second transmission ends protruding radially along the second shaft; and Two second stops are arranged circumferentially on the second rotating shaft; The two second transmission ends simultaneously press against the two second stop portions to form the phase holding structure.

[0012] Furthermore, the two second transmission ends are configured to have a certain phase angle difference, so as to simultaneously press against the two stop portions to transmit rotational power.

[0013] Furthermore, the massage device also includes a massage device that is linked to the rotating device via an eccentric component, the massage device being configured to be driven by the rotating device and to reciprocate along a set direction.

[0014] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model, by configuring a rotating device with a phase-changing structure, enables the two massage units of the massage device to generate a phase difference during rotation, thereby achieving asynchronous massage. Compared with traditional synchronous massage, this asynchronous massage mode can simulate more natural and diverse massage techniques, providing users with a richer and deeper massage experience, effectively enhancing the comfort and therapeutic effect of the massage. In addition, the design of the phase-changing structure allows the massage device to flexibly adjust the working state of the massage units according to the user's needs or the requirements of the massage program.

[0015] 2. The massage device of this invention can easily switch between synchronous and asynchronous massage modes as needed. When the phase difference is zero, the two massage units work synchronously, suitable for scenarios requiring a consistent massage rhythm; while when the phase change structure comes into play, it enters asynchronous massage mode to adapt to more diverse massage needs. This flexibility greatly enhances the applicability of the device and the user experience.

[0016] 3. Another rotating device of this utility model is configured as a phase-maintaining structure. Through the fixed connection of the second turntable and the second rotating shaft, and the simultaneous pressing of the two second transmission ends against the two second stop parts, the stability of the relative rotation between the rotating devices is ensured, thereby maintaining a constant phase relationship. The two second transmission ends are configured to have a certain phase angle difference (30°-180°) to meet the requirement of transmitting rotational power while simultaneously pressing against the two stop parts, further enhancing the stability and massage effect of the massage device.

[0030] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0031] Please see Figures 1-3This utility model discloses a massage device capable of asynchronous massage. The massage device includes a housing 100, two massage units 200 arranged at intervals, two rotating devices 300 for driving the massage units 200 respectively, and two massage devices 400. The massage device 400 is linked to the rotating device 300 via an eccentric member, and the massage device 400 is configured to be driven by the rotating device 300 and reciprocate along a set direction. A drive mechanism 500 and a transmission mechanism are provided inside the housing 100. In this embodiment, the drive mechanism 500 is a motor, which can be fixed to the housing 100. The transmission mechanism includes two sets of gear transmission mechanisms 600 connected to both ends of the output shaft of the motor. The gear transmission mechanism 600 includes a worm gear and gears that drive it. The transmission mechanism is a conventional technical solution in the field and will not be described in detail here.

[0032] Please see Figures 1-3 The massage unit 200 and the massage device 400 are respectively disposed on the housing 100. The devices are spaced apart along the width direction of the housing 100 and a certain distance is maintained between them. This distance is preferably approximately the same as the distance between the human shoulder and neck, which will not be elaborated further here.

[0033] Please see Figure 4 In this embodiment, one of the two rotating devices 300 is equipped with a phase-changing structure. The rotating device 300 includes a first turntable 310 and a first rotating shaft 320. Specifically, the phase-changing structure includes a first pin 301, two first stops 302, and a clearance space 303 formed between the two first stops 302. The first pin 301 is fixed to the first rotating shaft 320 and configured to rotate with the first rotating shaft 320. The two first stops 302 are arranged circumferentially at intervals on the first rotating shaft 320. In this embodiment, the first pin 301 has a first transmission end 3011 protruding from the outer circumference of the first rotating shaft 320. This first transmission end 3011 is adapted to selectively press against one of the two first stop portions 302 to transmit rotational power. Furthermore, when the first rotating shaft 320 changes its rotation direction, the first transmission end 3011 disengages from one first stop portion 302 and then presses against the other first stop portion 302 via the clearance space 303, thereby creating a phase difference between the two rotating devices 300 to implement asynchronous massage. The first transmission end 3011 protrudes radially outward from the first rotating shaft 320. The clearance space 303 can rotate at an angle of 30°-270°.

[0034] It should be noted that the asynchronous massage mode described in this application refers to the two massage units alternately performing massage actions with different rhythms, directions, or movements, forming a complementary or alternating massage mode. The movements of the two massage units are staggered or alternated, mimicking the effect of alternating hand massage or acupressure. By alternating movements, a larger area is covered, avoiding repeated stimulation of the same area and thus achieving a wider coverage. In this embodiment, when the massage head of one massage unit moves upward, the other moves downward, forming a wave-like massage. Alternating pressure is applied to the shoulders, neck, and waist to distribute pressure and avoid muscle stiffness.

[0035] Furthermore, when the phase difference between the two rotating devices is zero, a synchronous massage mode is executed between the two rotating devices. This synchronous massage mode refers to a massage mode in which the two massage units simultaneously perform massage actions with the same rhythm, direction, and movement. The massage trajectories are completely identical, such as simultaneous up-and-down movement, symmetrical kneading, or tapping. The synchronized movements of the two massage units can simulate the experience of simultaneous pressing or kneading with both hands. This massage mode is suitable for areas requiring even relaxation (such as the sides of the back, symmetrical areas of the shoulders), providing a balanced massage effect. In this embodiment, the massage heads in both massage units simultaneously move upwards from the waist to the shoulders and then synchronously return. Both can simultaneously knead the muscle groups on both sides of the spine with the same force.

[0036] In this embodiment, the first transmission end is defined as the first position when it presses against one of the two first stops, and is positioned as the second position when it presses against the other of the two first stops. When the first transmission end moves between the first position and the second position, it switches between the synchronous massage mode and the asynchronous massage mode.

[0037] Please see Figures 5-7One of the two rotating devices 300 is configured to form a phase-holding structure. This rotating device 300 includes a second turntable 304 and a second shaft 305, which are fixedly connected to form a phase-holding structure capable of limiting relative rotation between them. Specifically, the phase-holding structure includes two second drive ends 3051 protruding radially along the second shaft 305, and two second stops 306 arranged circumferentially spaced on the second shaft 305. The two second drive ends 3051 simultaneously press against the two second stops 306 to form the phase-holding structure. The two second drive ends 3051 are configured to have a certain phase angle difference to facilitate transmitting rotational power while simultaneously pressing against the two second stops 306. The phase difference between the two second drive ends 3051 is 30°-180°. In this embodiment, the two second transmission ends 3051 are configured to protrude outwards at both ends in opposite directions along the radial direction of the first rotating shaft 320. In other embodiments, the two transmission ends may also be configured to protrude outwards at both ends at a certain angle along the radial direction of the first rotating shaft 320, which will not be elaborated further here.

[0038] It should be noted that in this embodiment, one of the rotating devices 300 in the massage device is configured with a phase-changing structure, while the other rotating device 300 is configured with a phase-maintaining structure. The phase-changing structure includes a first turntable 310, a first rotating shaft 320, a first pin 301, and two first stop portions 302. The first pin 301 rotates with the first rotating shaft 320 and selectively presses against one of the two first stop portions 302 to transmit rotational power. When the first rotating shaft 320 changes its rotation direction, the first pin 301 disengages from the current stop portion and presses against the other stop portion after passing through the clearance space 303. Furthermore, the phase-maintaining structure, through the fixed connection of the second turntable 304 and the second rotating shaft 305, and the simultaneous pressing of the two second transmission ends 3051 against the two second stop portions 306, ensures the stability of the relative rotation between the rotating devices 300, thereby maintaining a constant phase relationship. This design allows the two rotating devices 300 to generate a phase difference when starting rotation or changing direction, thus achieving asynchronous massage. This design allows for more diverse massage movements and enhances the massage effect. It should be noted that in other embodiments, the two rotating devices can also be equipped with phase-changing structures simultaneously. However, the different angles at which the clearance space in the two phase-changing structures allows the first pin to rotate can also achieve a phase difference between the two rotating devices in this application to execute an asynchronous massage mode. For example, rotating one pin by 90° and the other pin by 270° can also achieve a phase difference of 180°, which will not be elaborated further here.

[0039] In this embodiment, each massage unit 200 includes a kneading head 210, which is fixed on the rotating device 300. The first rotating shaft 320 and the second rotating shaft 305, which are driven by the gear device, pass through the housing 100 and are fixed to the rotating device 300. Thus, when the motor is started, the rotating device 300 can be driven to rotate through the transmission mechanism.

[0040] Each set of massage devices 400 includes a connecting arm 410, a slider 420, and a roller assembly 430. The housing 100 has a groove extending in one direction, and the slider 420 can engage with this groove, allowing it to slide within it. In an embodiment of the invention, both ends of the connecting arm 410 are annular. The first end of the connecting arm 410 is positioned between the first turntable 310, the second turntable 304, and the housing 100. The surfaces of the first turntable 310 and the second turntable 304 opposite to the connecting arm 410 have circular eccentric members. A phase-changing structure and a phase-maintaining structure are disposed within this eccentric member. In this embodiment, the eccentric member can be inserted into and fixed to the first end of the connecting arm 410, thereby forming an eccentric connection between the first end of the connecting arm 410 and the first turntable 310 and the second turntable 304, and enabling them to move together. In other embodiments, the connecting arm 410 and the first turntable 310 and the second turntable 304 may also be connected to the eccentric position of the kneading head 210 base in other ways, which will not be elaborated on here.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
