Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] To better understand this solution, the up and down directions of the massage comb are defined in the context of its use: closer to the head is down, and farther from the head is up. Similarly, the front of the object is defined as closer to the head, and the back of the object as farther from the head. These directional terms are not intended to limit the scope of this solution.

[0021] like Figures 1 to 14As shown, the improved massage comb includes a housing 10, a massage component 20 located at the lower part of the housing 10, a handle component 30 located on one side of the housing 10, and a rear housing component 40 located at the upper part of the housing 10. A pulling mechanism is provided between the handle component 30 and the massage component 20. The massage component 20 includes a support plate 21 located in the middle of the housing 10, a massage head component 23 located on the lower side of the support plate 21 and engaged with multiple rotating blocks 22 on the support plate 21, and a swing component located on the upper side of the support plate 21 and slidably connected with multiple rotating blocks 22 on the support plate 21. The pulling mechanism drives the swing component to swing back and forth along the circumference of the support plate 21, while the swing component drives the rotating blocks 22 and the massage head component 23 to rotate back and forth along the radial direction of the support plate 21, thereby producing a massage effect on the head (referring to the human head).

[0022] Specifically, the pulling mechanism includes a drive assembly and a lever assembly. The drive assembly is located at one end of the handle assembly 30 near the housing 10, and the lever assembly is located inside the housing 10.

[0023] Specifically, the drive assembly includes a motor 50 located near the center of the handle assembly 30, a gear assembly 52 (including a gear shaft 520) rotatably connected to a worm gear 51 on the main shaft of the motor 50, and an eccentric gear 53 meshing with the gear assembly 52 near the inner end of the handle assembly 30. In this embodiment, the gear assembly 52 includes a worm gear / gear assembly 521 rotatably connected to the worm gear 51, a double gear 522 rotatably connected to the worm gear / gear assembly 521, a single gear 523 rotatably connected to the double gear 522, and the single gear 523 rotatably connected to the eccentric gear 53. (Note: For products with low noise requirements, a worm gear is used; for products with low noise requirements, a helical gear is used instead of a worm gear to reduce costs.) The eccentric gear 53 includes a main wheel disk 530 and a gear 531 located on one side of the main wheel disk 530, and a frustum 532 located on the other side of the main wheel disk 530. An eccentric column 533 is provided on the frustum 532, and a pad 534 is provided between the eccentric column 533 and the frustum 532 (which has the advantage of making the eccentric gear 53 rotate more flexibly). The eccentric column 533 is provided with a screw hole 5331 and a positioning pin 5332. A crescent-shaped cutout 5333 is provided between the screw hole 5331 and the positioning pin (which has the function of saving material and uniform material thickness).

[0024] Specifically, the pull rod assembly includes a pull rod 60, an eccentric washer 62 disposed on a connection hole 61 at one end of the pull rod 60, and an eccentric washer 62 disposed on a connection hole 61 at the other end of the pull rod 60. The connection hole 61 and the eccentric washer 62 at one end of the pull rod 60 are rotatably connected to the eccentric gear 53 by screws.

[0025] Specifically, the rotating block 22 includes a lower rotating body 221 and an upper upwardly protruding sliding column 222. Multiple rotating blocks 22 are distributed at intervals along the circles of the support disk 21 and are tangential to the circles. Each rotating block 22 has at least two circles with unequal radii; preferably, this embodiment has two circles. The rotating body 221 has a downwardly opening U-shaped shaft groove 2211, which matches and rotatably connects to the short shaft 211 on the support disk 21. The rotating body 221 also has a locking slot 2212.

[0026] The oscillating assembly includes an oscillating disk 70 and multiple flat drum-shaped holes 71 within the oscillating disk 70. Each flat drum-shaped hole 71 is spaced apart along the circumference of the oscillating disk 70 and forms an angle with the circumference. At least two rings of flat drum-shaped holes 71 are provided. The sliding column 222 is inserted into the flat drum-shaped hole 71 from bottom to top and slidably connected to it. To ensure smooth sliding and reduce mechanical noise, a suitable amount of lubricating oil is provided in the flat drum-shaped hole 71. Since the flat drum-shaped hole 71 is fitted outside the sliding column 222 and the back-and-forth sliding range is very short, it will not cause the lubricating oil to be easily splashed onto the lamp panel assembly like the internal gears listed in the background art. This is because internal gears rotate continuously in a circle, generating centrifugal force that splashes lubricating oil onto the lamp panel assembly. In this solution, the oscillating disk 70 only oscillates back and forth in the circumferential direction, with the angle formed by the oscillation amplitude being approximately 10-15°. It does not rotate continuously in a circle, so it does not generate centrifugal force and the lubricating oil will not be splashed onto the lamp panel assembly. Meanwhile, since the flat drum-shaped hole 71 is a structure that fits outside the sliding column 222, it also solves the problem listed in the background art that the internal gear assembly requirements are high and the peripheral teeth are prone to falling off.

[0027] Specifically, the swing plate 70 has an upward eccentric column 533 near the handle assembly 30, and the connecting hole 61 and eccentric washer 62 at the other end of the pull rod 60 are rotatably connected to the eccentric column 533 by screws.

[0028] Specifically, the massage head assembly 23 includes multiple sets of massage heads 231 (for example, in this embodiment, one set consists of four massage heads 231) and a soft front shell 232 located at the tail of the massage heads 231 for fixing the tail of the massage heads 231. The soft front shell 232 is also used to cover the outer edge of the support plate 21. The tail end of the massage head 231 is provided with a hook 2311, which matches and engages with the slot 2212 on the rotating body 221.

[0029] Specifically, the handle assembly 30 includes a handle bracket 31 and a handle housing 32. The handle bracket 31, from the inside out, includes a gearbox 311 (also equipped with a gearbox cover 3111), a motor housing 312, and a battery housing 313. The gearbox 311 houses the gear assembly 52 and the eccentric gear 53. The motor housing 312 houses the motor 50. The battery housing 313 contains a rechargeable battery 3130. A circuit board assembly 314 is located on one side of the handle bracket 31. A push-button switch 3141 is located near the inner end of the handle assembly 30 on the circuit board assembly 314. A charging socket 3142 is located at the rear end of the handle assembly 30 on the circuit board assembly 3141. The handle housing 32 is snap-fitted to the side tube 11. Figure 2 .

[0030] Specifically, the rear shell assembly 40 includes a rear shell 41, a decorative cover 42 disposed on the upper side of the rear shell 41 and fastened thereto, and a sealing cover 43 disposed in the middle of the upper side of the decorative cover 42. The sealing cover 43 includes a silicone part 431, a mounting part 432, and a decorative part 433 from the inside out. To prevent loss, the silicone part 431 is designed with an integrated clasp 4311, which is clamped between the rear shell 41 and the decorative cover 42.

[0031] Specifically, the massage component 20, the outer shell 10, and the rear shell assembly 40 are provided with a through-hole essential oil box assembly 80 at their center. The essential oil box assembly 80 includes a front shell 81, multiple essential oil tubes 82, oil tube sealing rings 83, and a bracket 84. The bracket 84 is used to fix the front shell 81 and the rear shell 41.

[0032] The inner end of the handle bracket 31 is inserted through the side tube 11 of the outer casing 10 and then fixedly connected to the tail of the front shell 81 of the essential oil box assembly 80 by screws. The rear shell 41 is fixedly connected to the outer casing 10 by screws on one side and to the bracket 84 of the essential oil box assembly 80 by screws on the other side. At the same time, the inner end of the handle assembly 30 is fixed by the tail of the front shell 81 of the essential oil box assembly 80. The massage component 20 is fixedly connected to the outer casing 10 by screws.

[0033] The rear shell 41 has an umbrella-like shape, with its central part serving as the essential oil storage chamber for the essential oil container assembly 80. The essential oil container assembly 80 of this product is equipped with an effect light featuring an internal light-transmitting mechanism (including a light-transmitting hole 841 in the bracket 84 and a transparent wall of the front shell 81, i.e., the front shell 81 is made of transparent material). The effect light is mounted on a light panel assembly 85, which is fitted onto the upper side of the bracket 84. To prevent water and oil leakage, the rear shell 41 is equipped with an outer shell sealing ring 44 and an oil passage sealing ring 45. The side tube 11 has two handle sealing rings 12, and the switch hole 13 on the side tube 11 has a button sealing sleeve 14. A button 33 is also located on the switch hole of the handle shell 32. The handle assembly 30 of this design has three prominent advantages: First, it makes full use of the internal space to accommodate the gear assembly 52, motor 50, rechargeable battery 3130, circuit board assembly 314, and charging base 3142, saving internal space and reducing the thickness of the massage comb. Second, it solves the problem of hand discomfort caused by holding the massage comb above the head for extended periods, as mentioned in the background art. Third, the switch in this design is located on the handle assembly 30 near the outer shell 10, preventing accidental activation when holding the product and making it very convenient to use. Furthermore, the overall product assembly is easy due to the multiple positioning mechanisms incorporated into the design, as shown in the accompanying drawings, which will not be listed here.

[0034] In summary, the technical solution of this utility model has the following beneficial effects: This solution addresses the six shortcomings of the patent described in the background technology. The unique rear shell structure of this solution is a crucial support component for the massage comb, resembling an umbrella shape and serving multiple functions: it acts as a fixing component for the outer shell, as well as for the essential oil box assembly, securing the inner end of the handle assembly via the front shell tail of the essential oil box assembly; it also serves as a fixing component for the decorative cover and sealing cover; and its central section is the essential oil storage cavity for the essential oil box assembly. This rear shell design offers multiple advantages, including multi-functionality, efficient space utilization, reduced internal components, lower product costs, and improved assembly efficiency. The sealing cover structure of this solution is rationally designed, consisting of an inner silicone component, an mounting component, and a decorative component.

The decorative component not only enhances the appearance of the sealing cover but also effectively prevents the silicone from prolonged exposure to air, thus avoiding aging. The mounting component serves as both a fixing component for the silicone component and a fixing component for the decorative component. The hand support in this design is also an optimized structural design, integrating the gearbox, motor box, and battery box from the inside out. The hand support features multiple structural windows and partial semi-openings, cleverly utilizing the circuit board assembly as a enclosure for the motor and rechargeable battery, thus saving materials.
