Abstract
Description
Technical Field
[0001] This utility model relates to the field of massager products, and more particularly to head massagers. Background Technology
[0002] A head massager is a device that helps the brain recover through massage. It massages the cerebral cortex, activates cell vitality and brain nerves, and has a brain-maintaining effect. It is also effective in relieving dizziness, headaches, neuralgia, and insomnia. The fast pace of modern work and life often leaves people in a state of fatigue, and prolonged fatigue can affect health. A head massager can unblock meridians, promote blood circulation, and help people relax.
[0003] Existing head massagers on the market achieve their massage function by rotating in a circumferential direction. This leads to a problem where, when the user has long hair, the rotating massage head can entangle the hair, resulting in a poor user experience. The existing Chinese patent application CN202223327578.7 for a massage comb addresses these shortcomings; however, it still has the following drawbacks:
[0004] (1) The ends of the first and second comb teeth that come into contact with the human head are both needle-rod structures, which will cause a stinging sensation on the human head during repeated massage.
[0005] (2) The poor design of the structure of the first protrusion and the first cam, as well as the structure of the second protrusion and the second cam, resulted in the need to set the first clearance groove and the second clearance groove, as well as the third clearance groove and the fourth clearance groove, which brought complexity to the mold structure.
[0006] (3) Multiple first comb teeth are connected end to end to form a ring structure, including the differentiated structure of active comb teeth and driven comb teeth. It also requires connecting parts between active comb teeth and driven comb teeth, resulting in a variety of parts and inconvenient assembly.
[0007] (4) The turntable and the external gear are two separate parts, which increases the mold cost and assembly time;
[0008] (5) A protective cover is also provided on the outside of the second comb tooth cover, which increases the cost of molds, materials and assembly time;
[0009] (6) The structure of the comb handle and the outer shell not only takes up space and wastes materials, but is also inconvenient to carry around.
[0010] To address these issues, this solution proposes a head massager. Utility Model Content
[0011] The purpose of this invention is to address six shortcomings in the existing patented structure of massage combs. The specific solutions are as follows:
[0012] A head massager includes a circular outer shell and a rear shell. A massage component concentric with the outer shell is provided at the front part of the outer shell. An essential oil component is provided in the middle of the massage component. A lamp panel assembly, a drive assembly, a circuit board, and a rechargeable battery are provided at the rear part of the outer shell.

The front of the swing seat is fastened to the rear of the massage rod. The front end of the massage rod is provided with a spherical massage head with an outer diameter larger than the outer diameter of the rod end. The rear protruding end of the swing seat is provided with a ball that slides in the slide rail of the track gear composite and swings radially with the slide rail. The rear of the essential oil assembly extends to the rear shell and is provided with an oil filling port. The front of the essential oil assembly is provided with multiple sliding oil outlet pipes. The sliding oil outlet pipes and the massage heads extend out of the front of the shell and contact the user's head.
[0013] Furthermore, the multiple sets of massage rods include multiple sets of massage rods on an inner ring distributed in a ring along the center of the outer shell, and multiple sets of massage rods on an outer ring.
[0014] Furthermore, the slide rail of the track gear composite includes an inner slide rail and an outer slide rail. The inner slide rail matches the ball of the swing seat at the rear of the multiple sets of massage rods on the inner ring, and the outer slide rail matches the ball of the swing seat at the rear of the multiple sets of massage rods on the outer ring.
[0015] Furthermore, an internal gear is provided on the reverse side of the track gear composite between the inner and outer slide rails, and this internal gear is rotatably connected to the drive assembly.
[0016] Furthermore, the drive assembly includes a drive housing, a motor disposed in the drive housing, a worm gear / gear composite that meshes with a worm on the motor spindle, and a double gear composite that meshes with the worm gear / gear composite, wherein another gear in the double gear composite meshes with the internal gear.
[0017] Furthermore, in each group of massage rods, the rear ends of multiple massage rods are arranged vertically at intervals on the front side of a rod base, the rear side of which is provided with two inverted buckles, and the periphery of the rod base is provided with grooves.
[0018] Furthermore, the flexible cover is provided with a plurality of recessed windows that match the rod seat, the inner wall of the recessed window is provided with a drum-shaped protrusion that matches the recessed groove, and the rear edge of the flexible cover is provided with an inward folded edge.
[0019] Furthermore, the bracket is provided with multiple strip-shaped swing windows that accommodate the swing seat, and each end of the swing window is provided with a short shaft. The flexible cover and the inner folded edge wrap around the bracket.
[0020] Furthermore, each end of the swing seat is provided with a U-shaped groove that matches the short shaft, and the front of the swing seat is provided with two buckle grooves that match the buckle.
[0021] Furthermore, the outer shell has an annular platform along its inner wall, and the annular platform has multiple screw holes and positioning holes. The inner folded edge of the flexible cover also has multiple corresponding screw holes and positioning holes. The rear edge of the bracket also has multiple corresponding screw holes and positioning pins. The positioning pins are inserted into the positioning holes on the inner folded edge and the annular platform in sequence. Multiple screws are inserted from back to front into the multiple screw holes on the annular platform, the rear edge of the bracket, and the inner folded edge to fix the outer shell, the bracket, and the flexible cover together. The track gear composite has a sliding ring, which is fitted around the middle of the essential oil component and slidably connected to the sliding platform surface in the middle.
[0022] In summary, the technical solution of this utility model has the following beneficial effects:
[0023] This solution addresses six shortcomings in the existing patented massage comb design. The flexible cover in this solution is made of silicone, offering waterproof, dustproof, and corrosion-resistant properties. It also allows for flexible movement with the massage rods, reducing mechanical noise. Furthermore, the sidewalls of the flexible cover are tightly fitted to the front edge of the outer shell, providing a seal to the front of the massager. Each massage rod is an integrated unit, molded together within the silicone mold used to produce the flexible cover, significantly reducing assembly time and improving efficiency. The spherical massage head at the front of the massage rod effectively prevents tingling on the head during massage. The oil dispenser in this solution features a spring and ball bearing structure at the front and a first sealing ring at the rear. A second sealing ring connects the front and rear oil shells, and the oil filling port on the rear shell uses a sealing cap. This ensures that the oil in the oil component does not leak or evaporate. The oil filling port is also designed very reasonably; adding oil does not require disassembling the oil component—simply pry open the piston in the sealing cap. The optimized and rational design of the swing seat structure in this solution ensures that the ball at the convex end will not interfere with adjacent objects during sliding and swinging with the inner and outer slide rails. Its U-shaped groove and snap-fit structure greatly facilitates product assembly, thereby improving assembly efficiency. The front oil shell uses a transparent material, and a light panel assembly is fitted around the rear oil shell. Multiple LEDs illuminate the front oil shell through multiple light-transmitting windows on the rear oil shell, enhancing the product's aesthetics. The lighting serves both decorative and charging / working status indication purposes. The drive assembly utilizes a drive housing, which reduces noise, prevents dust and lubricant evaporation, and better secures the motor, worm gear / gear composite, and double gear composite components, improving mechanical transmission precision. A third sealing ring is installed between the rear shell and the outer shell, ensuring a completely sealed front, back, and perimeter of the head massager, improving overall waterproofing and reducing overall mechanical noise.

[0041] Specifically, the multiple sets of massage rods 31 include multiple sets of massage rods 31 on an inner ring distributed in a ring along the center of the outer shell 10 and multiple sets of massage rods 31 on an outer ring.
[0042] Specifically, the slide rail 111 of the track gear composite 110 includes an inner slide rail 112 and an outer slide rail 113. The inner slide rail 112 matches the ball 321 of the swing seat 32 at the rear of the multiple sets of massage rods 31 on the inner ring, and the outer slide rail 113 matches the ball 321 of the swing seat 32 at the rear of the multiple sets of massage rods 31 on the outer ring.
[0043] Specifically, an internal gear 114 is provided on the reverse side of the track gear composite 110 between the inner slide rail 112 and the outer slide rail 113, and the internal gear 114 is rotatably connected to the drive assembly 60.
[0044] Specifically, the drive assembly 60 includes a drive housing 61, a motor 62 housed in the drive housing 61, a worm gear / gear composite 64 meshing with a worm 63 on the main shaft of the motor 62 (i.e., the worm 63 meshes with the lower worm gear 641 in the worm gear / gear composite 64), a double gear composite 65 meshing with the worm gear / gear composite 64 (i.e., the second gear 651 at the lower part of the double gear composite 65 meshes with the first gear 642 at the upper part of the worm gear / gear composite 64), and the other gear in the double gear composite 65, namely the third gear 652 at the upper part of the double gear composite 65, meshes with the internal gear 114. Note: If cost considerations are taken into account, the lower worm gear 641 can also be replaced by a helical gear. Detailed structure and installation of the drive assembly 60 are shown in its exploded view (e.g., ...). Figure 5 (As shown).
[0045] Specifically, in each group of massage rods 31, multiple massage rods 31 (four in this embodiment) are arranged vertically at intervals at their rear ends on the front side of a rod base 34. The rod base 34 has two inverted buckles 35 on its rear side and a groove 36 around its perimeter. Each group of massage rods 31 is an integrated structural component (that is, the massage rods 31, massage heads 33, rod base 34, inverted buckles 35, and grooves 36 are integrated into one piece), preferably made of plastic.
[0046] Specifically, the flexible cover 90 has multiple recessed windows 91 that match the rod base 34. The inner wall of each recessed window 91 has a drum-shaped protrusion 92 that matches the groove 36. The rear edge of the flexible cover 90 has an inner folded edge 93. In this design, the flexible cover 90 is preferably made of silicone. Each set of massage rods 31 plastic parts is placed into a silicone mold (not shown in the figure) used to produce the flexible cover 90 and molded together to form a silicone massage head assembly. This greatly saves assembly time and improves work efficiency.
[0047] Specifically, the bracket 100 is provided with a plurality of strip-shaped swing windows 101 that accommodate the swing seats 32. Each end of the swing window 101 is provided with a short shaft 102, a flexible cover 90 and an inner folded edge 93 that wrap around the bracket 100.
[0048] Specifically, each end of the swing seat 32 is provided with a U-shaped groove 37, which matches the short shaft 102, and the front of the swing seat 32 is provided with two buckle grooves 38 that match the buckle 35.
[0049] Specifically, the outer shell 10 has an annular platform 11 along its inner wall, which has multiple screw holes 12 and positioning holes 13. The inner folded edge 93 of the flexible cover 90 also has multiple corresponding screw holes 12 and positioning holes 13. The rear edge of the bracket 100 also has multiple corresponding screw holes 12 and positioning pins 103. The positioning pins 103 are inserted into the positioning holes 13 on the inner folded edge 93 and the annular platform 11 in sequence. Multiple screws (not shown in the figure) are inserted from back to front into the multiple screw holes 12 on the annular platform 11, the rear edge of the bracket 100 and the inner folded edge 93 to fix the outer shell 10, the bracket 100 and the flexible cover 90 to each other. The track gear composite 110 has a sliding ring 115, which is fitted around the middle of the essential oil component 40 and is slidably connected to the sliding platform 43 in the middle.
[0050] In this design, the sliding oil outlet tube 42 of the essential oil component 40 uses a spring 44 and a ball bearing 45 at the front end and a first sealing ring 46 at the rear end. A second sealing ring 49 is used at the connection between the front oil shell 47 and the rear oil shell 48 of the essential oil component 40. The filling port 41 of the rear oil shell 48 uses a sealing cap 21, ensuring that the clear oil in the essential oil component 40 will not leak or evaporate. The design of the filling port 41 is very reasonable; when adding essential oil, it is not necessary to disassemble the essential oil component 40; simply pry open the piston 22 in the sealing cap 21. The front oil shell 47 is made of transparent material. A light panel assembly 50 is fitted around the rear oil shell 48. Multiple LEDs (not shown in the figure) shine through multiple light-transmitting windows 481 of the rear oil shell 48 onto the front oil shell 47, enhancing the product's aesthetics. The lights serve both a decorative function and as an indicator of charging and operating status. In this design, a third sealing ring 23 is provided between the rear shell 20 and the outer shell 10, so that the front, back and sides of the entire head massager product are in a fully sealed state, which improves the overall waterproofness and reduces the overall mechanical noise.
[0051] The assembly process of the massage component 30 in this solution is briefly described as follows:
[0052] S1, invert the bracket 100 with the reverse side facing up, and install the U-shaped grooves 37 of the multiple swing seats 32 into the short shaft 102 of the swing window 101;
[0053] S2, the bracket 100 is fitted with a silicone massage head assembly (i.e., a composite of multiple massage rods 31 and flexible cover 90), the positioning post 103 is inserted into the positioning hole 13 of the inner folded edge 93 of the flexible cover 90, and the buckle 35 is fastened into the buckle groove 38.
[0054] S3, the track gear composite 110 is inverted and mounted on the bracket 100, so that the slide rail 111 is fitted on multiple spheres 321;
[0055] S4, insert the front oil housing 47 from the center to the middle of the flexible cover 90, bracket 100 and track gear composite 110, and then insert the pre-processed sliding oil outlet pipe 42 containing spring 44 and ball 45 into the corresponding hole of the front oil housing 47 from top to bottom after the first sealing ring 46 is fitted on it. Then, insert the second sealing ring 49 into the front oil housing 47.

[0057] S6, install the outer casing 10 onto the flexible cover 90 and the bracket 100, aligning the screw holes 12 and positioning holes 13 on the annular platform 11 with the screw holes 12 and positioning holes 13 and positioning pins of the flexible cover 90 and the bracket 100, and tighten them with screws driven into the screw holes 12; (see) Figure 10 )
[0058] S7. Insert the lamp panel assembly 50 onto the rear oil housing 48, ensuring that the positioning holes on the lamp panel assembly 50 are aligned with the screws. No screws are needed. Install the pre-prepared drive assembly 60 into the corresponding part of the housing 10 and tighten it with screws. (The drive assembly 60 will press down on the lamp panel assembly 50 to prevent it from coming out.)
[0059] S8, the rechargeable battery 80 is installed into the battery positioning block 14 of the housing 10. The rechargeable battery 80 can be attached to the lamp board assembly 50 using double-sided adhesive. The circuit board 70 is mounted on the fixing hole 611 on the drive housing 61 and fixed with screws; (see) Figure 11 )
[0060] S9, place the sealing cap 21 onto the oil filling port 41, place the button 24 on the power switch 71 of the circuit board 70, put the third sealing ring 23 into the side groove of the back cover 20, and then cover the back cover 20 onto the outer shell 10. Make sure that the button 24 and the charging socket 72 on the circuit board 70 are exposed at the corresponding holes on the back cover 20, and use screws to fasten the back cover 20 to the outer shell 10.
[0061] Special note: If a slim and stylish design is desired, this solution can be slightly modified by replacing the internal gear with an external gear and placing the drive assembly, circuit board, and rechargeable battery inside the handle.
