Description

Technical Field

[0001] This utility model relates to the field of shoulder and neck massager technology, and in particular to a shoulder and neck massager that combines kneading and tapping functions. Background Technology

[0002] In the field of healthcare equipment, shoulder and neck massagers use mechanical rolling and squeezing to knead the meridians of the shoulder and neck, stimulate acupoints, relax muscles, and promote blood circulation, thereby achieving healthcare effects.

[0003] However, existing products generally only have unidirectional low-speed kneading, lacking a tapping function, with limited techniques and insufficient stimulation depth, making it difficult to quickly relieve fatigue. To add tapping modes, manufacturers often add extra power systems and positioning sensors, resulting in more parts, thicker bodies, increased costs, and decreased reliability under continuous vibration.

[0004] The market urgently needs an integrated transmission structure that can simultaneously generate low-speed, high-torque kneading and high-speed, short-stroke tapping with a single power source. This would reduce thickness, number of parts, lower costs, and improve reliability, making shoulder and neck massagers thin, wearable, with a variety of techniques, and significantly improved cost-effectiveness. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a shoulder and neck massager that combines kneading and tapping functions, so as to solve the problem that the existing shoulder and neck massagers can only knead the neck and shoulders, without tapping function, with monotonous movements, poor massage effect, and cannot effectively relieve human fatigue.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A shoulder and neck massager that combines kneading and tapping functions includes a housing, and a drive structure is provided inside the housing. The drive structure includes a motor, a transmission component, a first drive assembly, and a second drive assembly. A first drive assembly includes a first worm, a first rotating shaft, a first transmission wheel, a second transmission wheel, and an eccentric rod. The first transmission wheel and the second transmission wheel are fixedly mounted on the second rotating shaft. The first worm and the first rotating shaft are rotatably mounted on a housing. The first worm is arranged in a direction perpendicular to the first rotating shaft. The first transmission wheel is fixedly mounted on one end of the first rotating shaft near the first worm, and the first transmission wheel meshes with the first worm. An eccentric rod is connected to both ends of the first worm, and the eccentric rod is fixed to the first swing arm by bearings. The second drive assembly includes a second worm, a second rotating shaft, a third transmission wheel, a fourth transmission wheel, an eccentric wheel, and a connecting rod. The second worm and the second rotating shaft are rotatably mounted on the housing. The third transmission wheel is fixed on the second rotating shaft and meshes with the second worm. The fourth transmission wheel is fixed at one end of the second worm. The second and fourth transmission wheels are respectively connected to the transmission component. Eccentric wheels are symmetrically fixed at both ends of the second rotating shaft. One end of each eccentric wheel is provided with a second swing arm, and the other end is hinged to a first swing arm via a connecting rod. A first massage head is fixed at one end of the first swing arm, and a second massage head is fixed at one end of the second swing arm.

[0007] Preferably, the transmission component is a third worm gear, and the output end of the motor is fixedly connected to the third worm gear.

[0008] Preferably, the first transmission wheel has more teeth than the first worm, and the third transmission wheel has more teeth than the second worm.

[0009] Preferably, it also includes a battery and a housing, wherein when the housing is fixed to the casing, it forms a receiving space for accommodating the battery, and the battery is electrically connected to the motor.

[0010] Preferably, the first massage head is spherical.

[0011] Preferably, the second worm is arranged in a direction perpendicular to the second rotating shaft, the second worm is arranged parallel to the first rotating shaft, and the second rotating shaft is arranged parallel to the first worm.

[0012] Preferably, a sealing plate is fixed to the side of the housing facing away from the neck, and the sealing plate cooperates with the housing to enclose the first transmission wheel, the second transmission wheel, the third transmission wheel, the fourth transmission wheel and the motor.

[0013] Preferably, the second massage head is provided with a plurality of micro-bulb lamps, which are electrically connected to a battery.

[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are: This utility model discloses a shoulder and neck massager that combines kneading and tapping functions. The invention utilizes a motor to drive a transmission component, which in turn rotates a fourth transmission wheel. The fourth transmission wheel then rotates a second worm gear, which in turn rotates an eccentric wheel. This achieves the kneading function of the first and second massage heads in existing shoulder and neck massagers. When the motor is activated, it drives the transmission component, which in turn rotates the second transmission wheel and simultaneously the first transmission wheel. Since the first transmission wheel meshes with the first worm gear, it drives the first worm gear to rotate. Because both ends of the first worm gear are connected... The device features an eccentric rod. When the first worm rotates, it drives the eccentric rod to move up and down, which in turn drives the first swing arm to perform a tapping motion. This causes the first massage head to tap the shoulders, while the second massage head continues to knead the neck. This achieves both tapping and kneading functions for the shoulders and neck, making the function more comprehensive, improving the massage effect, and thus better relieving fatigue. Furthermore, by using the engagement of the first worm with the first transmission wheel and the second worm with the third transmission wheel, the positions of each worm and transmission wheel are more compact, resulting in a smaller overall size of the shoulder and neck massager.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0017] like Figures 1-3 and Figure 6 As shown, this utility model provides a shoulder and neck massager with both kneading and tapping functions. The feature is that it includes a housing 1, wherein the housing 1 can be divided into a first half-shell 11 and a second half-shell 12 fixed by screws. A first drive assembly and a second drive assembly are fixedly disposed in the housing and encapsulated by the first half-shell 11 and the second half-shell 12. The screw fixation facilitates the disassembly and assembly of the first drive assembly and the second drive assembly.

[0018] The housing 1 is provided with a drive structure 2, which includes a motor 21, a transmission component 22, a first drive assembly, and a second drive assembly. The first drive assembly includes a first worm gear 23, a first rotating shaft 24, a first transmission wheel 25, a second transmission wheel 26, and an eccentric rod 27. The first transmission wheel 25 and the second transmission wheel 26 are fixedly mounted on the second rotating shaft 24. The first worm gear 23 and the first rotating shaft 24 are rotatably mounted on the housing 1. The first worm gear 23 is arranged in a direction perpendicular to the first rotating shaft 24. The first transmission wheel 25 is fixedly mounted on one end of the first rotating shaft 24 near the first worm gear 23. The first transmission wheel 25 meshes with the first worm gear 23. The eccentric rod 27 is connected to both ends of the first worm gear 23. The eccentric rod 27 is fixed to the first swing arm 3 by bearings. The second drive assembly includes a second worm gear 28, a second rotating shaft 29, a third transmission wheel 30, a fourth transmission wheel 31, and an eccentric wheel 210. The second worm gear 28 and the second rotating shaft 29 are rotatably mounted on the housing 1. The third transmission wheel 30 is fixed on the second rotating shaft 29 and meshes with the second worm gear 28. The fourth transmission wheel 31 is fixed at one end of the second worm gear 28. The second transmission wheel 25 and the fourth transmission wheel 31 are respectively connected to the transmission component 22. The eccentric wheels 210 are symmetrically fixed at both ends of the second rotating shaft 29. One end of the eccentric wheel 210 is provided with a second swing arm 4, and the other end is hinged to a first swing arm 3 through a connecting rod 211. A first massage head 5 is fixed at one end of the first swing arm 3, and a second massage head 6 is fixed at one end of the second swing arm 4.

[0019] By starting the motor 21, the motor 21 drives the transmission component 22 to move, the transmission component 22 drives the fourth transmission wheel 31 to rotate, the fourth transmission wheel 31 drives the second worm gear 28 to rotate, and the second worm gear 28 drives the eccentric wheel 210 to rotate, thereby realizing the kneading work of the first massage head 5 and the second massage head 6 of the existing shoulder and neck massager; the specific principle is existing technology and will not be described in detail here.

[0020] Based on the above, when the motor 21 is started, it drives the transmission component 22 to move. The transmission component 22 drives the second transmission wheel 26 to rotate, and at the same time drives the first transmission wheel 25 to rotate. Since the first transmission wheel 25 meshes with the first worm 23, the first transmission wheel 25 drives the first worm 24 to rotate. Since both ends of the first worm 23 are connected to eccentric rods 27, and the eccentric rods 27 are fixed to the first swing arm 3 through bearings, when the first worm 23 rotates, it will drive the eccentric rods 27 to move up and down, thereby driving the first swing arm 3 to perform up and down tapping motion, so that the first massage head 5 taps on the person's shoulders, while the second massage head 6 continues to knead the person's neck. This achieves the functions of tapping and kneading on the person's shoulders and neck, making the function more comprehensive, improving the massage effect, and thus better relieving the fatigue of the human body.

[0021] Furthermore, by engaging the first worm gear 23 with the first transmission wheel 25, and the second worm gear 28 with the third transmission wheel, the positions of each worm gear and transmission wheel are more compact, resulting in a smaller overall size for the shoulder and neck massager. Compared to multi-stage worm gear meshing, the worm gear-worm wheel layout with its 90° vertical staggered arrangement allows for a large reduction ratio in a single stage, eliminating unnecessary gears and resulting in a shorter axial dimension. The progressive contact of the helical tooth surfaces ensures smooth transmission and low noise. The independent insertion of the worm gears and their one-time press-fit with the injection-molded worm wheels simplify assembly, allow for loose tolerances, and facilitate mass production, making the entire device lighter, quieter, and more reliable, perfectly meeting the needs of wearable massagers.

[0022] like Figure 4 As shown, the transmission component 22 is the third worm gear. The output end of the motor 21 is fixedly connected to the third worm gear. The second transmission wheel 26 and the fourth transmission wheel 31 are respectively meshed with the third worm gear. When the motor 21 is started, the motor 21 drives the third worm gear to rotate, thereby driving the second transmission wheel 26 and the fourth transmission wheel 31 to rotate. The second transmission wheel 26 drives the first transmission wheel 25 to rotate, thereby driving the first worm gear 23 to rotate. The fourth transmission wheel 31 drives the second worm gear 28 to rotate, thereby driving the third transmission wheel to rotate. Among them, the first transmission wheel 25 has more teeth than the first worm gear 23, and the third transmission wheel 30 has more teeth than the second worm gear 28.

[0023] This application's transmission mechanism achieves coordinated output of two massage modes under a single motor drive through a gear pair with a specific gear ratio. Specifically, since the first transmission wheel 25 has more teeth than the first worm 23, the rotational speed of the first worm 23 can be increased, thereby increasing the frequency of the up-and-down movement of the eccentric rod 27 and ultimately increasing the tapping speed of the first massage head 5. Conversely, the third transmission wheel 30 has more teeth than the second worm 28 (i.e., the second worm 28 has fewer teeth than the third transmission wheel 30), thus relatively reducing the rotational speed of the third transmission wheel 30, which in turn reduces the rotational speed of the second shaft 29 and the eccentric wheel 210, and consequently relatively reduces the movement speed of the second massage head 6, thereby reducing the kneading speed of the second massage head 6. Therefore, under the drive of the same motor 21, this design can simultaneously achieve the faster-frequency tapping of the first massage head 5 and the slower-frequency kneading of the second massage head 6, meeting people's needs for shoulder and neck massage.

[0024] Driven by the same motor 21, and utilizing different gear ratios, the dual-mode massage of "fast tapping and slow kneading" is simultaneously achieved in the same transmission system. This not only simplifies the structure and reduces manufacturing costs, but also reduces the overall size, making the shoulder and neck massager lighter and more compact, making it easier for users to carry and use. At the same time, it meets users' dual massage needs for shoulder tapping and neck kneading, improving the massage experience and user comfort.

[0025] like Figure 5 As shown, it also includes a battery 7 and a housing 8. When the housing 8 is fixed to the housing 1, it forms a housing space to accommodate the battery 7. The battery 7 is electrically connected to the motor 21, and the battery 7 can provide power to drive the motor 21.

[0026] In one embodiment, such as Figure 1-3 As shown, the first massage head 5 is spherical. This spherical design allows for a smoother contact surface between the first massage head 5 and the human body, effectively avoiding potential localized stinging or discomfort during high-frequency tapping, significantly improving user comfort. The absence of sharp edges when in contact with the shoulder increases the contact area, disperses pressure, and reduces localized stinging. Simultaneously, the sphere can slightly slide across the skin, reducing friction damage and making the high-frequency tapping force more even and comfortable, enhancing the soft and conforming feel during kneading, and meeting the dual needs of different users for both gentle and deep massage.

[0027] In one embodiment, such as Figure 4As shown, the second worm 28 is arranged perpendicular to the second rotating shaft 29, and the second worm 28 is arranged parallel to the first rotating shaft 24. The second rotating shaft 29 is arranged parallel to the first worm 23. The second worm (28) and the second rotating shaft 29 are arranged perpendicularly, and the three shafts are parallel and orthogonally stacked in pairs, so that the kneading and tapping transmission chains are staggered at 90° in the same three-dimensional space, avoiding axial interference and significantly reducing the length and thickness of the compressor housing; the vertical meshing improves the overlap, reduces side clearance, and makes the whole machine structure more compact and smaller in size, easily achieving a thin and wearable design.

[0028] like Figure 6 As shown, a sealing plate 9 is fixed to the side of the housing 1 facing away from the neck. The sealing plate 9, together with the housing 1, encloses the first transmission wheel 25, the second transmission wheel 26, the third transmission wheel 30, the fourth transmission wheel 31, and the motor 21, so that the first transmission wheel 25, the second transmission wheel 26, the third transmission wheel 30, the fourth transmission wheel 31, and the motor 21 are in a relatively sealed environment, effectively preventing dust, sweat, and foreign objects from entering, reducing gear wear and noise, and extending the service life of the whole machine; at the same time, the sealing plate acts as a load-bearing wall, enhancing the rigidity of the housing, reducing vibration deformation, making the structure more compact, and the operation quieter and more reliable.

[0029] In one embodiment, the second massage head 6 is equipped with a plurality of micro-bulb lamps, which are electrically connected to a battery 7. The micro-bulb lamps are powered by the battery 7. The second massage head 6 integrates heating and red light therapy functions, and can output warmth and specific wavelength light while kneading / tapping, promoting local blood circulation, relaxing muscles and improving massage comfort. The light source and heat source are concentrated on the skin surface, resulting in low energy consumption, rapid heating, no need for additional wiring, simplified structure and improved user experience.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
