Description

Technical Field

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

[0002] Existing head massagers typically include a comb and a handle. Because the handle is long and thin while the head is large, and the head is usually round or nearly elliptical, which are not convenient shapes for placement, head massagers can only be placed flat and cannot be placed upright or hung, making them difficult to store and taking up a lot of space when placed. Utility Model Content

[0003] To at least solve one of the above-mentioned technical problems, one objective of this utility model is to provide a head massager that can be hung up and is easy to store.

[0005] The head massager of this utility model has a hollowed-out part in the comb. The hollowed-out part can be used as a hanging hole, so that the head massager can be hung on other objects or on the wall through the hollowed-out part, so that the head massager can be better stored and save storage space. In addition, the hollowed-out part forms a gap between the middle area and the outer peripheral area, which can reduce the interference between the components in the middle area and the outer peripheral area.

[0006] In some embodiments, the head massager further includes teeth and a drive mechanism.

Detailed Implementation

[0036] Although the present invention can be readily embodied in various forms of implementation, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0037] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0038] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, inside, outside, left, right, front, back, etc.) used to explain the structure and movement of the various components of this invention are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0039] It should also be noted that when the connection between components is described as "fixed to" or "set on" another component, the component can be directly on the other component or there may be an intervening component. When a component is described as "connected" to another component, it can be directly connected to the other component or indirectly connected to the other component.

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the description of the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0041] The preferred embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. In the following embodiments, the vertical directions such as above, below, and directly below are all... Figure 2 The vertical direction is indicated.

[0042] refer to Figures 1 to 11 As shown, the head massager 10 of this utility model embodiment includes a handle 1 and a comb head 2. The comb head 2 and the handle 1 are connected. The handle 1 includes a handle housing 11, and the comb head 2 includes a head housing 21, which is connected to the handle housing 11. The comb head 2 is provided with a functional module and comb teeth 3. The comb head 2 includes a central region X and an outer peripheral region Y. The functional module is located in the central region X, and the comb teeth 3 are located in the outer peripheral region Y. A hollow portion 22 is provided between the central region X and the outer peripheral region Y, which separates the central region X and the outer peripheral region Y.

[0043] The head massager of this utility model embodiment features a hollowed-out section, allowing it to be hung on other objects or a wall for better storage and to save space. The hollowed-out section creates a partition between the central and outer areas, reducing interference between components in these areas. For example, if the central area contains a heating element, the hollowed-out section can insulate against heat, preventing the outer components from aging rapidly due to prolonged heating. Furthermore, the hollowed-out section on the comb head also enhances the aesthetics of the head massager.

[0044] The cutout portion 22 can be annular or other shapes. When the cutout portion 22 is an annular cutout ring, it can be a completely closed ring or a non-closed ring. In some specific embodiments, the cutout portion 22 is a non-closed annular cutout ring with connecting portions 23 at both ends. The connecting portions 23 connect the central region X and the outer peripheral region Y, so that the central region X and the outer peripheral region Y are not completely separated. The connecting portions allow the shell covering the central region and the shell covering the outer peripheral region to be processed into a single component, making the entire head shell easy to process and assemble. It also facilitates the passage of wires when electronic components are located inside both the central region X and the outer peripheral region X, allowing the electronic components in the central region and the outer peripheral region to be electrically connected through wires.

[0045] Comb teeth 3 are provided on the comb head 2. Multiple sets of comb teeth 3 are spaced apart. Each comb tooth 3 includes a tooth portion 32 and a linkage portion 31. The tooth portion 32 typically includes multiple columnar teeth arranged circumferentially along the head shell 21. The free ends of the columnar teeth form bumps 324 to increase the contact area with the scalp and improve massage comfort. The handle 1 includes a handle shell 11; the comb head 2 includes a head shell 21 connected to the handle shell 11. The linkage portion 31 is located inside the comb head 2. At least a portion of the teeth 32 is exposed outside the head shell 21. The bumps 324 at the free ends of the teeth 32 are used to contact the scalp for massaging the head. The linkage portion 31 is provided with a connecting groove 311. The connecting groove 311 can be formed by a recessed connecting end or by a protruding rib 312 on the connecting end, such as... Figure 10 As shown, the connecting groove 311 is formed by the spacing between the two raised ribs 312 on the connecting end of the comb tooth 3. The ribs 312 can be strip-shaped structural members or plate-shaped structural members, etc.

[0046] The comb head is equipped with teeth 4, which can be disc-shaped or ring-shaped. The ring shape facilitates the arrangement of other components in the middle of the comb head. The teeth 4 are located inside the head housing 21. The outer wall of the teeth is provided with meshing teeth 4242. The lower end face of the teeth facing the tooth part 32 is provided with a rib 41. The rib 41 is wavy in the circumferential direction of the teeth and is inserted into the connecting groove 311 of multiple comb teeth 3.

[0047] The head massager 10 also includes a drive mechanism 5, which is located within the handle housing 11 and / or the head housing 21. Specifically, the drive mechanism 5 can be located within the handle housing 11, the head housing 21, or partially within both. Preferably, the drive mechanism 5 is primarily located within the handle housing 11, with the portion connected to the teeth 4 extending into the head housing 21 of the comb. The drive mechanism 5 is connected to the teeth 4 via a transmission mechanism, enabling the teeth 4 to rotate. When the teeth 4 rotate, the engagement of the ribs 41 and the connecting groove 311 causes the comb teeth 3 to oscillate outwards and inwards. By providing wavy ribs on the lower end face of the teeth, which insert into the connecting grooves of the comb teeth, the rotation of the teeth, through the engagement of the ribs and the connecting grooves, allows the comb teeth to oscillate outwards and inwards. This design not only simplifies the structure but also achieves a comfortable, hand-like kneading massage effect.

[0048] like Figures 1-2 , Figures 6-8 As shown, the comb head 2 is circular, and the teeth 32 include multiple sets of first teeth 321 and multiple sets of second teeth 322. The multiple sets of first teeth 321 are spaced apart along the circumference of the comb head 2, and the multiple sets of second teeth 322 are also spaced apart along the circumference of the comb head and are located radially inside the first teeth 321. A set of first teeth 321 and a set of second teeth 322 that are opposite each other along the radial direction of the comb head are connected to each other and are connected to the same linkage part 31. That is, a single linkage part can drive the movement of both inner and outer comb teeth, simplifying the structure of the comb teeth, effectively saving internal space of the comb head, and reducing the number of connecting slots that the ribs need to be inserted into, making it easier to align the ribs with the connecting slots during assembly, making assembly simpler and faster.

[0049] A limiting plate 6 is provided on the side of the toothed component 4 away from the comb teeth 3. The limiting plate 6 is clearance-fitted with the upper end face of the toothed component 4. The limiting plate 6 is used to restrict the movement of the toothed component 4 away from the connecting groove 311. The limiting plate above the toothed component can prevent the scalp from pushing against the comb teeth during the massage process. If the comb teeth push against the toothed component, causing the toothed component to move upward away from the scalp, the limiting plate can prevent the toothed component from continuing to move upward when it touches the limiting plate. This keeps the toothed component in a position that can mesh with the drive mechanism, ensuring the normal movement of the comb teeth and preventing the comb teeth from detaching from the scalp.

[0050] The comb head 2 has a functional module in the middle, which can be one or more of the following: liquid storage module 7, heating element, and infrared lamp assembly. The toothed part 4 is ring-shaped and surrounds the outer periphery of the functional module 7.

[0051] In some preferred embodiments, the functional module includes a liquid storage module 7, which includes a liquid storage chamber 71 and multiple liquid outlet tubes 72. The first end of each outlet tube 72 is connected to the liquid storage chamber 71, and the outlet tubes 72 extend away from the liquid storage chamber 71 and can contact the scalp. The second end of each outlet tube 72 has an outlet. The liquid storage chamber 71 is mainly used to store medicinal liquids that promote hair growth, or medicinal liquids with effects such as promoting blood circulation and removing blood stasis. The outlet tubes 72 guide the medicinal liquid from the liquid storage chamber 71 to the scalp. The top of the liquid storage chamber 71 has an openable cover 75, which can be opened to add medicinal liquid.

[0052] A spring 73 is installed inside the liquid outlet tube 72, and a ball bearing 74 is installed at the liquid outlet. The ball bearing 74 is located at the liquid outlet to block the liquid outlet. When the ball bearing 74 contacts the scalp and is pushed by the scalp into the liquid outlet tube 72, the liquid outlet is opened and the spring 73 is compressed. When the ball bearing 74 is not pushed, the spring 73 returns to its original position, causing the ball bearing 74 to return to its original position, and the liquid outlet is blocked.

[0053] The comb head 2 also includes a head shell 21 and a lower shell 100. The lower shell 100 is connected to the head shell 21 to enclose and form the inner cavity of the comb head 2. The inner cavity facilitates the assembly of teeth, linkage parts, and some electronic components. The comb teeth 3 are connected to the lower shell 100 and extend downward in a direction away from the lower shell 100 to form teeth 32. The lower shell 100 may include a hard plastic part on the upper side and a flexible soft plastic part 1001 on the bottom end. The flexible soft plastic part 1001 is provided so that the comb teeth 3 can be elastically stretched when they swing. In order to improve the waterproof performance of the head massager, the flexible soft plastic part 1001 is integrally formed with the teeth 32 of the comb teeth 3.

[0054] The comb 2 has a middle frame 8 in its inner cavity. The middle frame 8 includes a bottom wall 81, an inner wall 82, and an outer wall 83. The toothed component 4 is located above the bottom wall 81. The middle frame 8 with the outer wall 83 can limit and protect the outer edge of the toothed component 4. The head housing 21 has a mounting cavity 211, in which the middle frame 8 and the teeth 4 are both located. The mounting cavity 211 includes a first sidewall 2111 on the outer side and a second sidewall 2112 on the inner side. The linkage part 31 has a rotating shaft 313 at both ends. The middle frame has an opening 84 for the avoidance connection groove 311. The comb teeth 3 are mounted on the lower cover 100. The upper side of the middle frame 8 is connected to the head housing 21, specifically by a snap-fit ​​connection between the inner sidewall 82 of the frame and the head housing 21. The middle frame 8 is also connected to the lower cover 100, specifically by a screw connecting the middle frame to the hard plastic part of the lower cover 100. The rotating shaft 313131 is clamped between the bottom wall 81 of the frame and the lower cover 100. This not only limits the linkage part but also allows the rotating shaft to rotate, enabling the comb teeth to swing inward or outward.

[0055] The limiting plate 6 includes a horizontal plate 61 and a vertical plate 62 bent and connected to the horizontal plate 61. The horizontal plate 61 is located above the gear 4 and is clearance-fitted with the upper end face of the gear 4. The vertical plate 62 is located between the inner ring side of the gear 4 and the second side wall 2112, and its lower end abuts against the inner side wall 82 of the frame. The top wall of the mounting cavity 211 is provided with a first top post 2113 facing the gear 4, and the first top post 2113 abuts against the upper end face of the horizontal plate 61. By setting the limiting plate with a horizontal plate and a vertical plate, the limiting plate can be fixed more conveniently. The horizontal plate abuts against the first top post, and the vertical plate abuts against the inner side wall of the frame, thereby fixing the limiting plate without the need for fixing with screws or other fasteners, effectively simplifying the fixing method of the limiting plate.

[0056] The head massager 10 also includes a power supply board 200 and a battery 300, both of which are installed inside the handle housing 11 of the handle 1. The battery 300 supplies power to the power supply board 200 and other electrical components. A sensor is located inside the head housing 21 and is connected to the power supply board 200. A first magnetic element 43 is provided on the toothed component 4. The first magnetic element 43 is preferably a magnet, but other magnetically attached components can also be used. The first magnetic element can be located in a groove formed on the upper surface of the toothed component, with a rib on the lower surface. The first magnetic element 43 is positioned between the most protruding and most recessed positions of the corresponding rib 41. The power supply board 200 controls the drive mechanism 5 to stop operating when the sensor detects the sensing signal of the first magnetic element 43. The first magnetic component is positioned between the most protruding and most recessed positions of the corresponding rib. In this position, when the head massager stops working, the corresponding comb teeth are in their original position, essentially vertically downwards. In this state, the comb teeth do not fold inwards, preventing them from trapping hair, and they also do not point outwards, ensuring the product looks aesthetically pleasing. This embodiment ensures that when the user presses the power button, the magnetic component causes the comb teeth to swing back to their original, reset position, thus preventing hair from being trapped and restoring the product to its original, aesthetically pleasing state.

[0057] The sensing element includes a Hall element 91. When the gear 4 rotates to the position of the first magnetic element 43 and approaches the Hall element 91, the Hall element 91 generates a potential difference under the action of the magnetic field of the first magnetic element 43. This potential difference forms a sensing signal, and the controller receives this sensing signal and responds.

[0058] The comb head 2 also includes a Hall circuit board 92, which is electrically connected to the power main board 200. A single Hall element 91 is mounted on the Hall circuit board 92. Multiple first magnetic elements 43 are evenly distributed on the teeth 4. The presence of multiple first magnetic elements 43 allows for a quick power-off response when the user presses the power-off button, requiring only minor rotation of the teeth, and ensuring the comb teeth remain in their original position when powered off. The top wall of the mounting cavity 211 has a second top post 2114 facing the teeth 4. The second top post 2114 abuts against the upper surface of the Hall circuit board, while the lower surface of the Hall circuit board is supported by a limiting plate.

[0059] like Figure 3 , Figure 7 and Figure 9As shown, the drive mechanism 5 includes a motor 51, a gearbox 52, and a transmission gear set. The motor 51 and gearbox 52 are located inside the handle housing 11. The output end of the gearbox 52 is provided with a bevel gear head 521. The transmission gear set includes a first bevel gear 53, a first gear 54, and a second gear 55. The first bevel gear 53 is located on the lower side near the tooth portion 32, that is, below the central axis inside the handle 1. The first bevel gear 53 meshes with the bevel gear head 521. The first gear 54 is coaxially arranged with the first bevel gear 54 and located on the upper side of the first bevel gear 54. The second gear 55 meshes with both the first gear 54 and the gear member 4. Figure 3 In the vertical direction indicated, the first bevel gear 53 is positioned on the lower side of the handle 1, and the first gear 54 is positioned on the upper side of the first bevel gear and is basically located at the central axis of the handle. In this way, in the vertical direction, the second gear, which serves as the output gear, can be at approximately the same height as the central axis of the motor and is basically located on the central axis of the handle. Consequently, the gear meshing with the second gear can also be located approximately in the middle of the comb head, allowing for better layout of the components within the comb teeth and ensuring that the thickness of the handle is controlled within an optimal range.

[0060] The head housing 21 and the handle housing 11 are integrally injection molded, such as Figures 6-8 and Figure 11 As shown, the head shell 21 and the handle shell 11 are injection molded into a single piece using plastic. Integrating the handle shell and the comb shell into a single injection molded unit avoids poor sealing at the connection point, improves the waterproof performance of the head massager, and makes it easier to use the head massager in wet environments (such as when washing hair) or to rinse and clean it with water.

[0061] The head shell 21 has a recessed cavity 212 formed in the middle towards the toothed portion 32. A liquid storage cavity 71 is disposed within the cavity 212. A first through hole 2121 is provided on the bottom wall of the cavity 212. One end of the liquid outlet tube 72 communicates with the liquid storage cavity 71, and the other end passes through the first through hole 2121 and is exposed to contact the scalp. The comb teeth 3 surround the outer periphery of the liquid outlet tube 72. By providing a downwardly recessed cavity on the head shell, the liquid storage module can be easily placed directly into the cavity, and the liquid outlet tube extends outward through the first through hole, making it very convenient to assemble the liquid storage module.

[0062] The functional module also includes a heating element 400, which can be a heating plate, heating wire, or heating film, preferably a graphene heating film. The heating plate is formed on the printed circuit board of the heating film. Using a graphene heating film can improve heating efficiency. The heating element 400 is located in the central area and below the liquid storage chamber 71. The heating element 400 is close to or attached to the bottom wall of the cavity 212, so that the heat from the heating element can be quickly transferred to the bottom wall of the cavity for more efficient radiation to the scalp, which helps to enhance the heat therapy effect on the head. In the presence of the liquid storage module, the heat can promote the absorption of the medicine by the scalp.

[0063] A connecting part 23 is provided at the tail end of the hollow section to facilitate the electrical connection between the electronic components of the outer peripheral area Y of the handle 1 or the comb head 2 and the middle area X of the comb head via wires. Specifically, wires are threaded through the connecting part, and the wires are respectively connected to the heating element 400 and the power supply main board 200. The heating element and the power supply main board can be directly connected or indirectly connected. For example, the wires in the connecting part connect the heating element to the power supply main board, or the heating element can be connected to the Hall circuit board, and then the Hall circuit board can be connected to the power supply main board via other wires.

[0064] The bottom wall of the liquid storage chamber 71 is provided with a first through hole 2121, and the heating element 400 is provided with a second through hole 4001. The liquid outlet tube 72 passes through the second through hole 4001 and the first through hole 2121 in sequence and then protrudes to form a liquid supply comb. The heating element is located below the liquid storage chamber, that is, in the area directly opposite the liquid outlet tube in the vertical direction. This allows the scalp area containing the liquid to be heated while the liquid is flowing out to the scalp, which quickly and effectively promotes the absorption of the liquid by the scalp. At the same time, the heat compress can also promote blood circulation in the scalp and help relieve symptoms such as headaches.

[0065] A temperature sensor 4002 is provided on or beside the heating element 400. A thermostat is used to control the heating range of the heating element to a suitable temperature for the human scalp, avoiding risks such as burns. The head massager also includes a heat insulation component 500, which is located between the heating element 400 and the bottom wall of the liquid storage chamber 71. The heat insulation component isolates the heat from the heating element from the liquid storage chamber, reducing the amount of medicine in the liquid storage chamber radiated by the heat from the heating element and preventing prolonged heating from affecting the efficacy of the medicine.

[0066] like Figure 3 and Figure 4As shown, the functional module also includes an infrared lamp assembly, which comprises multiple lamp bodies 6001 capable of emitting infrared light. A lamp plate 600 is located in the middle area of ​​the comb, below the liquid storage chamber 71. Multiple lamp bodies 6001 are mounted on the lamp plate 600, emitting infrared light to promote drug absorption and / or provide phototherapy to the head. The multiple lamp bodies 6001 are distributed circumferentially along the lamp plate 600. A light-transmitting area 2122 is provided on the bottom wall of the cavity 212, through which light from the lamp bodies 6001 is emitted. A light-transmitting area 2122 surrounds the outer periphery of multiple liquid outlet tubes 72. The inner wall of the light-transmitting area 2122 facing the interior of the cavity 212 has a concave structure 2123. Light from the lamp body 6001 is focused by the concave structure 2123 and emitted from the bottom wall of the cavity 212. The light emitted by the lamp body 6001 forms a ring around the liquid outlet tubes on the bottom wall of the cavity. The light-transmitting area is located on the bottom wall of the cavity containing the liquid storage module and surrounds the liquid storage tubes. This not only enables scalp therapy through red light but also allows for red light irradiation of the scalp area containing the liquid and surrounding areas while the liquid flows to the scalp, further promoting deeper penetration of the liquid and improving hair loss. Furthermore, the concave structure facing the lamp body in the light-transmitting area effectively focuses the light emitted by the lamp body, ensuring that most of the light reaches the scalp and improving the efficiency of the red light's effect on the scalp.

[0067] There are multiple concave structures 2123 distributed circumferentially. The positions of the multiple concave structures 2123 are directly opposite the positions of the multiple lamp bodies 6001 in the vertical direction. In this way, the light emitted by each lamp body directly illuminates the concave structure, resulting in a better light-focusing effect.

[0068] In some embodiments, a heating element 400 and a lamp plate 600 with multiple lamp bodies are simultaneously provided below the liquid storage cavity 71. In the vertical direction, the lamp plate 600 is located between the liquid storage cavity 71 and the heating element 400. A heat insulation element 500 is connected to the heating element 400 and disposed on the side of the heating element 400 facing the liquid storage cavity 71. The heat insulation element 500 is a mica sheet. The comb of the head massager simultaneously houses the heating element and the lamp plate. When the head massager is working, it can simultaneously activate heating and infrared irradiation functions, which can better promote the absorption of the medicine and provide a therapeutic effect on the head. Furthermore, the heating element is located on the bottom wall of the cavity, further away from the liquid storage cavity, to prevent heat from being blocked by the heating plate and thus not effectively acting on the scalp. Connecting the heat-insulating mica sheet to the heating element effectively isolates the upward-facing heat, reducing not only the impact of heating on the medicine but also the impact of heat radiation from the lamp plate.

[0069] like Figure 4 , Figure 6 and Figure 7As shown, the upper light panel 600 is larger than the heating plate, and the lamp body 6001 is positioned outside the area where the projections of the light panel 600 and the heating plate overlap in the vertical direction, so that the light from the lamp body 6001 is not blocked by the heating plate and can be directly directed towards the light-transmitting area 2122. Of course, the light panel can also be configured as a ring, with the central area directly opposite the heating plate being hollow.

[0070] Embodiments of this utility model also provide a head massager assembly, such as... Figure 12 As shown, in addition to any of the head massagers 100 described above, a holder 70 for placing the head massager is also provided. The hollowed-out portion can be hung on the holder 70. The holder 70 has a resting portion 701 that can fit into the hollowed-out portion, that is, the resting portion can be inserted into the hollowed-out portion 22, so that the resting portion 701 supports the hollowed-out portion 22, allowing the head massager to be hung on the holder 70. The resting portion is designed as a ring with a shape that is basically the same as that of the hollowed-out portion, so that the resting portion fits better with the hollowed-out portion, and the head massager is hung more stably on the holder.

[0071] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Because this application can be embodied in many forms without departing from the spirit or essence of the embodiments, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
