Description

Technical Field

[0001] This utility model relates to the field of household massage equipment technology, and in particular to a massager. Background Technology

[0002] With technological advancements and evolving health-conscious consumer demands, handheld massagers are gaining increasing importance due to their portability, flexibility, and immediacy in relieving muscle fatigue and improving local blood circulation. In today's fast-paced world, the demand for efficient and lightweight daily health care tools has significantly increased. Handheld massagers, with their lightweight design and ergonomic grip, can meet users' massage needs anytime, anywhere, and are gradually becoming an important tool for personal health management.

[0003] Current handheld massagers primarily utilize built-in micro-vibration motors to generate high-frequency vibrations, transmitting mechanical waves to the skin and deep tissues. This creates localized stimulation in the vibrated area, mimicking the "pressing" or "tapping" effects of traditional massage techniques to relax muscles and stimulate acupoints. However, existing technology generally relies on a single-dimensional vibration mode. The effective range is limited by the motor's vibration amplitude and frequency. When the user fixes the massager's position, the vibration energy can only cover a limited area, making it difficult to achieve large-area massage coverage within a given time. This necessitates frequent manual adjustments to expand the effective range, reducing efficiency and consistency of the experience. Furthermore, the single-dimensional vibration mode results in a less rich and varied massage sensation. Utility Model Content

[0004] The main purpose of this invention is to provide a massager that aims to expand the massage area and enrich the massage sensation per unit time by combining various movements.

[0005] To solve the above problems, the massager includes:

[0006] A housing having a receiving cavity with an opening; and

[0007] A composite motion mechanism includes a vibration motor and a first rotating assembly. The first rotating assembly includes a first rotary motor and a rotating component. The first rotary motor is disposed within the receiving cavity, and the rotating component is connected to the output shaft of the first rotary motor. The rotating component has a curved portion, and the vibration motor is disposed at the free end of the curved portion. At least a portion of the vibration motor passes through the opening to be exposed in the receiving cavity.

[0008] In one embodiment of the present invention, the massager further includes a motor mounting base, and the vibration motor is disposed in the motor mounting base; the free end of the curved portion is inserted into the motor mounting base.

[0009] In one embodiment of the present invention, the curved portion includes a first curved segment and a second curved segment connected together. The first curved segment is located closer to the first rotary motor than the second curved segment. The cross-sectional dimension of the second curved segment is smaller than that of the first curved segment. The bottom wall of the motor mounting base is provided with a locking hole, and the second curved segment passes through the locking hole.

[0010] In one embodiment of the present invention, the composite motion mechanism further includes a second rotating component, which includes a second rotating motor, an eccentric component, and a swing bracket. The second rotating motor is fixedly disposed in the receiving cavity. The eccentric component is connected to the output shaft of the second rotating component. The eccentric shaft of the eccentric component is inserted into the swing bracket so that the swing bracket performs reciprocating swing motion under the drive of the second rotating component.

[0011] The first rotary motor is connected to the free end of the swing bracket.

[0012] In one embodiment of this utility model, the swing bracket is provided with a guide groove, and the eccentric shaft of the eccentric member is inserted into the guide groove.

[0013] In one embodiment of the present invention, the free end of the swing bracket is provided with a motor fixing groove, and the first rotary motor is disposed in the motor fixing groove.

[0014] In one embodiment of this utility model, the inner peripheral wall of the housing is provided with a swing guide groove, and the outer peripheral surface of the swing bracket has a guide member, the guide member being inserted into the swing guide groove; and,

[0015] The inner peripheral wall of the housing is provided with a rotation limiting shaft, and the end of the swing bracket near the eccentric part is provided with a rotation hole, and the rotation limiting shaft is inserted into the rotation hole.

[0016] In one embodiment of this utility model, the massager is further provided with a massage soft sleeve, which covers the housing; the massage soft sleeve is provided with a massage part, and the vibration motor abuts against the massage part.

[0017] In one embodiment of the present invention, the massage part includes a covering protrusion and a massage protrusion, the covering protrusion enclosing a massage space, and the massage protrusion being located in the massage space; the vibration motor is inserted into the massage protrusion.

[0018] In one embodiment of this utility model, the covering protrusion has a corrugated bottom wall, and the corrugated bottom wall is connected to the massage protrusion;

[0019] The corrugated bottom wall conceals the opening of the receiving cavity.

[0020] In this invention, by installing a vibration motor at the free end of the curved portion of the first rotating component, the vibration motor vibrates at high frequency while the rotating component moves, causing the vibration wave to periodically sweep across the skin surface along a circular path. This effectively expands the stimulation of a single vibration source into a ring or fan-shaped area within a unit of time, significantly increasing the effective massage area and reducing the need for manual frequency adjustment by the user. Simultaneously, the high-frequency vibration of the vibration motor simulates the traditional "pressing / tapping" effect, while the rotational motion generates a shearing force similar to "kneading" or "massage." The superposition of these two mechanical modes creates a composite sensation, breaking through the monotony of a single vibration mode. This enhances the stimulation of acupoints, promotes blood flow, and provides better auxiliary health care. Furthermore, it helps users relieve stress, release emotions, and enter a relaxed state.

[0032] Please see Figure 1 The massager includes a housing 10 and a compound motion mechanism: the housing 10 has a receiving cavity 10a with an opening; the compound motion mechanism includes a vibration motor 20 and a first rotating assembly 30, the first rotating assembly 30 includes a first rotating motor 31 and a rotating member 32, the first rotating motor 31 is disposed in the receiving cavity 10a, and the rotating member 32 is connected to the output shaft of the first rotating motor 31; the rotating member 32 has a bent portion 321, and the vibration motor 20 is disposed at the free end of the bent portion 321; at least part of the vibration motor 20 passes through the opening to be exposed in the receiving cavity 10a.

[0033] In this utility model, by installing the vibration motor 20 at the free end of the curved portion 321 of the first rotating component 30, the vibration motor 20 vibrates at high frequency while the rotating component 32 moves by rotating itself, causing the vibration wave to periodically sweep across the skin surface along a circular path. This is equivalent to expanding the stimulation of a single vibration source into a ring or fan-shaped area within a unit of time, significantly increasing the effective massage area and reducing the need for manual frequency adjustment by the user. At the same time, the high-frequency vibration of the vibration motor 20 simulates the traditional "pressing / tapping" effect, while the rotational motion generates a shearing force similar to "kneading" or "massage." The superposition of these two mechanical modes creates a composite sensation, breaking through the monotony of a single vibration mode, thereby enhancing the stimulation of acupoints, promoting blood flow, and playing a better auxiliary health care role. Furthermore, it helps users relieve stress and release emotions, entering a relaxed state.

[0034] Specifically, in this embodiment, the housing 10 is composed of two symmetrical half-shells, each half-shell having an arc-shaped notch (understandably, the arc-shaped notch can be a semi-circular notch). The two half-shells are assembled and enclosed by means of bonding, snap-fitting, screwing, etc., to form a receiving cavity 10a with an opening. The power supply 60, circuit board 70, wires, and other structures of the massager are fixed in the receiving cavity 10a. At the same time, a first rotating assembly 30 is provided in the receiving cavity 10a. The first rotating motor 31 and the rotating component 32 of the first rotating assembly 30 are fixed in the receiving cavity 10a. The bent portion 321 of the rotating component 32 passes through the opening of the receiving cavity 10a. The vibration motor 20 at the free end of the bend 321 is fully exposed in the receiving cavity 10a. Meanwhile, a control panel 80 is provided outside the housing 10. The control panel 80 has multiple control buttons, each electrically connected to a circuit board 70. Both the first rotary motor 31 and the vibration motor 20 are electrically connected to the circuit board 70. By pressing different control buttons, different massage modes of the massager can be achieved. For example, in the first mode, only the vibration motor 20 is active; in the second mode, both the vibration motor 20 and the first rotary motor 31 are active. In this mode, driven by the first rotary motor 31, the rotating component 32 rotates with the output shaft of the motor. Please refer to [link to relevant documentation]. Figure 1The rotational motion shown in the diagram forms a circular trajectory at the free end of the curved section 321. The vibration motor 20 located at the free end of the curved section 321 translates along the circular trajectory while vibrating. When the massager is applied to acupoints, the combined circular motion of the vibration can increase the massage area without changing the position of the massager. The combination of two motion modes effectively enhances the stimulation of acupoints, promotes blood flow, and provides better auxiliary health care. Furthermore, it helps users relieve stress, release emotions, and enter a relaxed state. It is understood that the circumference of the motion trajectory can be changed by setting different curvatures of the curved section 321. Here, the curvature of the curved section 321 is not limited.

[0035] In one embodiment, the massager further includes a motor mounting base 11, in which a vibration motor 20 is disposed. The free end of the bent portion 321 is inserted into the motor mounting base 11. Specifically, the motor mounting base 11 has a hollow structure, thereby forming a limiting groove adapted to the size of the vibration motor 20. The vibration motor 20 is fixed in the limiting groove to ensure its stability during operation and to prevent the motor from shifting or loosening during vibration, which would affect the massage effect. At the same time, the motor mounting base 11 can ensure that the vibration motor 20 always maintains its initial posture and position during rotation, so that the vibration waves can be evenly transmitted to the skin surface, enhancing the massage effect. Furthermore, a silicone buffer layer is provided on the inner wall of the limiting groove to prevent vibration from being transmitted to the housing 10 and generating resonance noise, thereby improving the user experience.

[0036] Further, please refer to Figure 2 The curved portion 321 includes a first curved section 3211 and a second curved section 3212 connected together. The first curved section 3211 is located closer to the first rotary motor 31 than the second curved section 3212. The cross-sectional dimension of the second curved section 3212 is smaller than that of the first curved section 3211. The bottom wall of the motor mounting base 11 is provided with a locking hole, through which the second curved section 3212 passes. Specifically, the first curved section 3211, which is closer to the first rotary motor 31, has a larger cross-sectional dimension, which can play a supporting and torque-transmitting role, while providing sufficient structural strength for the entire rotating component 32. The smaller cross-sectional dimension of the second curved section 3212 makes it easier to insert into the locking hole of the motor mounting base 11. In this way, it can be ensured that the rotating component 32 maintains a precise motion trajectory during rotation, avoiding the vibration motor 20 from affecting the massage effect due to shaking during rotation, and ensuring that the vibration wave can act evenly on the skin surface. At the same time, the insertion of the second curved section 3212 into the locking hole can improve the assembly efficiency of the massager and make it easier to disassemble and replace parts during maintenance.

[0037] To further enhance the massage experience, please refer to Figure 1 and Figure 3The compound motion mechanism also includes a second rotating assembly 40, which includes a second rotating motor 41, an eccentric member 42, and a swing bracket 43. The second rotating motor 41 is fixedly disposed in the receiving cavity 10a. The eccentric member 42 is connected to the output shaft of the second rotating assembly 40, and the eccentric shaft of the eccentric member 42 is inserted into the swing bracket 43, so that the swing bracket 43 performs reciprocating swing motion under the drive of the second rotating assembly 40. Specifically, the first rotating motor 31 is connected to the free end of the swing bracket 43. The second rotating motor 41 is disposed near the bottom wall of the housing 10, and an eccentric member 42 is fixed on the output shaft of the second rotating motor 41. The swing bracket 43 has a connecting... The lateral connection of the eccentric shaft of the eccentric component 42, the swing bracket 43, the first rotary motor 31, the rotating component 32, the motor mounting base 11, and the vibration motor 20 are arranged along the first direction of the receiving cavity 10a. The swing bracket 43, the eccentric component 42, and the second rotary motor 41 are arranged along the second direction of the receiving cavity 10a. The first and second directions are perpendicular or the angle between the first and second directions tends to be right angle, thereby providing more wiring space in the receiving cavity 10a and avoiding the problem of wires from multiple motors getting tangled. The second rotary motor 41 is electrically connected to the circuit board 70. Pressing the control button can make the second rotary motor 41 drive the eccentric component 42 to rotate. Please refer to [link to relevant documentation]. Figure 1 The reciprocating oscillating motion shown in the figure is achieved by the eccentric component 42 converting the rotation of the second rotary motor 41 into the oscillation of the oscillating bracket 43 through the action of the eccentric shaft. Thus, the massager has a third mode, in which the vibration motor 20, the first rotary motor 31, and the second rotary motor 41 are all in working condition at the same time. At this time, the movement path of the vibration motor 20 is a composite movement trajectory of reciprocating oscillation and circular movement, thereby further expanding the massage area per unit time and enriching the massage sensation.

[0038] In one embodiment, please refer to Figure 3 The swing bracket 43 is provided with an eccentric guide groove 43a. The eccentric shaft of the eccentric member 42 is inserted into the eccentric guide groove 43a. Specifically, a lateral connecting part is provided on the side of the swing bracket 43 facing the eccentric shaft. The lateral connecting part is provided with an eccentric guide groove 43a. The eccentric shaft of the eccentric member 42 is inserted into the eccentric guide groove 43a and moves in the eccentric guide groove 43a, thereby driving the swing bracket 43 to perform reciprocating swing motion.

[0039] Furthermore, the free end of the swing bracket 43 is provided with a motor fixing slot, and the first rotary motor 31 is located in the motor fixing slot. The motor fixing slot can provide a stable installation position for the first rotary motor 31. By fixing the motor in the fixing slot, it can be ensured that the first rotary motor 31 will not shift or loosen during operation, thereby ensuring the stable operation of the massager.

[0040] In one embodiment of this utility model, please refer to Figure 2 The inner peripheral wall of the housing 10 is provided with a swing guide groove 10b, and the outer peripheral surface of the swing bracket 43 is provided with a guide member 431. The guide member 431 is inserted into the swing guide groove 10b. Specifically, the inner peripheral wall of the housing 10 is provided with an arc-shaped protrusion, and the arc-shaped protrusion is provided with a swing guide groove 10b along its own extension direction. At the same time, the rod-shaped guide member 431 is inserted into the swing guide groove 10b. In this way, the swing bracket 43 can be prevented from deviating from its movement. Furthermore, the inner peripheral wall of the housing 10 is provided with a rotation limit shaft 12, and the end of the swing bracket 43 near the eccentric member 42 is provided with a rotation hole. The rotation limit shaft 12 is inserted into the rotation hole to form a swing fulcrum, thereby ensuring the movement accuracy of the swing bracket 43.

[0041] In one embodiment of this utility model, please refer to Figure 4 The massager also features a massage sleeve 50, which can be made of soft and elastic materials such as silicone or sponge. The massage sleeve 50 covers the shell 10, providing a soft contact surface for the user and avoiding the discomfort that may be caused by the hard shell 10 directly contacting the skin, thus improving the comfort of use. The massage sleeve 50 has a massage part, and the vibration motor 20 abuts against the massage part, so that the vibration generated by the vibration motor 20 can be transmitted to the skin surface through the soft massage part, enhancing the gentleness and penetration of the massage, while reducing direct friction on the skin and avoiding skin damage.

[0042] Further, please refer to Figure 4 The massage section includes a covering protrusion 51 and a massage protrusion 52. The covering protrusion 51 encloses and forms a massage space, and the massage protrusion 52 is located in the massage space. The vibration motor 20 is inserted into the massage protrusion 52. Specifically, the covering protrusion 51 can enclose and form a massage space with a cross-section of any shape, such as a circle, ellipse, or square. The covering protrusion 51 can better fit the surface of the human body, making the massager more closely connected to the human body and improving the massage effect. The massage protrusion 52 is located in the central area of ​​the massage space. The side of the massage protrusion 52 facing the opening of the receiving cavity 10a has a hollow structure so that the vibration motor 20 can be inserted into the massage protrusion 52 and thus fixedly connected to the massage soft sleeve 50.

[0043] In one embodiment of this utility model, please refer to Figure 4The covered protrusion 51 has a corrugated bottom wall 511, which is connected to the massage protrusion 52. The corrugated bottom wall 511 covers the opening of the receiving cavity 10a. Specifically, the corrugated bottom wall 511 has multiple protrusion structures so that when the massage protrusion 52 undergoes compound movement, it can provide sufficient deformation margin, thereby preventing the massage soft sleeve 50 from hindering the movement of the vibration motor 20 due to self-deformation. At the same time, the corrugated bottom wall 511 covers the opening of the receiving cavity 10a, which can prevent dust and impurities from entering the receiving cavity 10a and protect the internal vibration motor 20 and other components.

[0044] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
