Detailed Implementation

[0033] 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 also understood that this specification should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] refer to Figures 1 to 12 As shown, the massage comb of this utility model embodiment includes a handheld part 1 and a comb head 2. The handheld part 1 includes a first housing 11; the comb head 2 includes a second housing 21, which is connected to the first housing 11; comb teeth 3 are disposed on the comb head 2, and the comb teeth 3 include multiple sets, which are spaced apart. The comb teeth 3 include tooth portions 32 and linkage portions 31. The tooth portions 32 typically include multiple columnar teeth arranged circumferentially along the second housing 21. The free ends of the columnar teeth form bumps 324 to increase the contact surface with the scalp and improve massage comfort. The linkage portion 31 is located inside the second housing 21, and at least a portion of the tooth portions 32 is exposed outside the second housing 21. The bumps 324 at the free ends of the tooth portions 32 are used to contact the scalp to massage the comb 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 9 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.

[0040] The comb head 2 is equipped with a transmission component, which can be a toothed component 4 with meshing teeth. The toothed component 4 is located inside the second housing 21. The outer wall of the transmission component is equipped with meshing teeth 42. The lower end face of the transmission component facing the toothed portion 32 is equipped with a rib 41. The rib 41 is wavy in the circumferential direction of the transmission component. The rib 41 is inserted into the connecting groove 311 of multiple comb teeth 3.

[0041] The massage comb also includes a drive mechanism 5, which is located within the comb head or handheld part 1. Specifically, the drive mechanism 5 can be located within the first housing 11, the second housing 21, or partially within both. Preferably, the entire drive mechanism is located within the first housing 11 of the handheld part, with the portion connected to the teeth 4 extending into the second housing 21 of the comb head. 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 grooves 311 causes the comb teeth 3 to oscillate outwards and inwards. This method of driving the kneading massage effect utilizes a wavy rib on the lower end face of the teeth, which inserts into the connecting groove of the comb teeth. When the teeth rotate, the engagement of the ribs and the connecting grooves causes the comb teeth to oscillate outwards and inwards, resulting in a simple structure and a comfortable, hand-like kneading massage effect.

[0042] like Figure 1 , Figures 5-7 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 circumferentially along the second housing 21, and the multiple sets of second teeth 322 are also spaced apart circumferentially along 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 radially along 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.

[0043] 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.

[0044] The comb has a liquid-filling component 7 in the middle, with ring-shaped teeth 4 surrounding the outer periphery of the liquid-filling component 7. The liquid-filling component 7 includes a liquid storage chamber 71 and multiple liquid outlet tubes 72. The first end of each liquid outlet tube 72 is connected to the liquid storage chamber 71, and the liquid outlet tubes 72 extend away from the liquid storage chamber 71 and can contact the scalp. The second end of each liquid outlet tube 72 has a liquid outlet. The liquid storage chamber 71 is mainly used to store some medicinal liquids that promote hair growth, or some medicinal liquids with effects such as promoting blood circulation and removing blood stasis. The liquid outlet tubes 72 guide the medicinal liquid in 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.

[0045] 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.

[0046] A boss 76 protruding toward the axis of the outlet pipe 72 is formed on the first end of the outlet pipe 72. One end of the spring 73 inside the outlet pipe 72 rests on the boss 76, and the other end of the spring rests on the ball bearing 74. By providing a boss protruding toward the inside of the pipe at the first end of the outlet pipe, one end of the spring can be fixed, which effectively simplifies the fixing structure of the spring. Moreover, the boss is usually integrally machined with the outlet pipe, so no additional assembly is required, which is a clever design.

[0047] The comb also includes a lower cover 100, which is connected to the second housing 21. The comb teeth 3 are connected to the lower cover 100 and extend downward in a direction away from the lower cover 100 to form teeth 32. The lower cover 100 may include a hard plastic part on the upper side and a flexible soft plastic 1001 on the bottom end. The flexible soft plastic 1001 is provided so that the comb teeth 3 can stretch elastically when they swing. In order to improve the waterproof performance of the massage comb, the flexible soft plastic 1001 is integrally formed with the teeth 32 of the comb teeth 3.

[0048] The comb has a middle frame 8 inside, which 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, which has an outer wall 83, can limit and protect the outer edge of the toothed component 4. The second 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 housing 100. The upper side of the middle frame 8 is connected to the second housing 21, specifically by a snap-fit ​​connection between the inner sidewall 82 of the frame and the second housing 21. The middle frame is also connected to the lower housing 100, specifically by a screw connecting the middle frame to the hard plastic part of the lower housing 100. The rotating shaft 313 is clamped between the bottom wall 81 of the frame and the lower housing 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.

[0049] 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.

[0050] The massage comb includes a main control board 200 and a battery 300, both of which are installed inside the first housing 11 of the handheld part 1. The battery 300 supplies power to the main control board 200 and other electrical components. A sensing element is provided inside the second housing 21, and the sensing element is connected to the main control board 200. A first magnetic element 43 is provided on the teeth 4, which is typically a magnet. The first magnetic element 43 is positioned between the most protruding and the most recessed positions of the corresponding ribs 41. The main control board 200 controls the drive mechanism 5 to stop working when the sensing element detects the sensing signal of the first magnetic element 43. When the massage comb stops working in this position, the corresponding comb teeth are in their original positions, with the comb teeth basically vertically downward. In this state, the comb teeth do not fold inward, so they will not trap hair, and the comb teeth do not point outward, so the user will not find the product unsightly. This embodiment of the solution enables the comb teeth to swing back to their original reset position when the user presses the power button, thereby preventing hair from being caught and restoring the product to its aesthetically pleasing state.

[0051] The sensing element includes a Hall element 91. When the toothed member 4 rotates to the position of the first magnetic member 43 and approaches the Hall element, the Hall element generates a potential difference under the action of the magnetic field of the first magnetic member 43. This potential difference forms a sensing signal, and the controller receives this sensing signal and responds.

[0052] The sensing element also includes a Hall circuit board 92, which is electrically connected to the main control board 200. One or more Hall elements are located on the Hall circuit board, and multiple first magnetic elements 43 are evenly distributed on the comb teeth 4. The presence of multiple first magnetic elements allows for a quick power-off response when the user presses the power-off button, requiring only a small rotation of the comb teeth, and ensuring the comb teeth remain in their original position when powered off. The top wall of the mounting cavity 211 is provided with a second top post 2114 facing the comb 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.

[0053] like Figure 2 and Figure 6 As shown, the drive mechanism 5 includes a motor 51, a gearbox 52, and a transmission gear set. The motor 51 and gearbox 52 are housed within the first 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 near the lower side of the toothed portion 32, that is, below the central axis inside the handheld portion 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 above the first bevel gear 54. The second gear 55 meshes with both the first gear 54 and the toothed portion 44. Figure 2In the vertical direction indicated, the first bevel gear is positioned on the lower side of the handle, and the first gear is positioned on the upper side of the first bevel gear and is approximately located on 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 motor axis and is approximately 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.

[0054] The second housing 21 and the first housing 11 are integrally injection molded, such as Figures 5-7 and Figure 10 As shown, the second housing 21 and the first housing 11 are injection molded into a single piece using plastic. The outer shell of the handle and the outer shell of the comb are integrally injection molded, resulting in a seamless connection between the first and second housings. This avoids poor sealing at the joint, improves the waterproof performance of the massage comb, and makes it easier to use in wet environments (such as when washing hair) or to rinse and clean with water.

[0055] The comb 2 also has a heating element 400 in its middle section. The heating element 400 can be a heating plate, heating wire, or heating film, preferably a graphene heating film. A heating plate is formed on the printing plate of the heating film. Using a graphene heating film can improve heating efficiency. In the vertical direction of the comb, the heating element 400 is located directly below the liquid storage chamber 71 to heat the scalp area contacted by the liquid outlet tube. The heating element is located directly below the liquid storage chamber, that is, in the vertical direction, directly opposite the liquid outlet tube. This allows the scalp area containing the liquid to be heated as the liquid flows out, quickly and effectively promoting the absorption of the liquid by the scalp. Moreover, the heating element can be used alone when no liquid is being used. Using the heating element alone for heat application can promote scalp blood circulation and help relieve symptoms such as headaches.

[0056] The middle part of the second housing 21 is recessed towards the toothed portion 32 to form a cavity 212. 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 pipe 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 pipe 72. By providing a downwardly recessed cavity on the second housing, the liquid filling component can be easily placed directly into the cavity, and the liquid outlet pipe extends outward through the first through hole, making it very convenient to assemble the liquid filling component.

[0057] The heating element 400 is located inside the cavity 212 and is close to or attached to the bottom wall of the cavity 212, so that the heat from the heating element can be dissipated more quickly through the bottom wall of the cavity to be transferred to the scalp. Preferably, the bottom wall of the cavity can be made of metal to improve heat conduction efficiency.

[0058] The massage comb also includes a heat insulation component 500 located between the heating element 400 and the bottom wall of the liquid storage chamber 71. This heat insulation component can be made of various materials to insulate against heat, such as heat-insulating plastic or mica sheets. The heat insulation component isolates the heat from the heating element from the liquid storage chamber, reducing the amount of medicine radiated from the heating element and preventing prolonged heating from affecting the efficacy of the medicine. Furthermore, the heat insulation component reduces the upward flow of heat from the heating element into the liquid storage chamber, allowing more heat to flow downwards towards the scalp during use, thus increasing heat utilization and preventing unnecessary heat waste.

[0059] The preferred embodiment of the heat insulation component 500 is a mica sheet, and the heating element 400 is preferably a graphene heating film or a graphene heating plate. The mica sheet is attached to the end face of the heating element 400 facing the liquid storage cavity 71. By selecting the mica sheet, not only is the heat insulation effect good, but it is also easy to fix directly to the heating element, which makes the assembly of the mica sheet simple. For example, the mica sheet can be glued to the heating plate that serves as the heating element.

[0060] A temperature sensor 80 is installed on the heating element 400. The temperature sensor 80 is used to control the heating range of the heating element to a suitable scalp temperature, avoiding risks such as burns. An elastic resin component 70 is also installed inside the comb. The elastic resin component 70 is located above the heating element 400 and below the liquid reservoir 71. The elastic resin component 70 is used to press the temperature sensor 80 firmly onto the heating element 400. Specifically, the elastic resin component can be a flexible part made of resin materials such as rubber or silicone. Fixing the temperature sensor with the elastic resin component protects the temperature sensor through its elasticity and also presses the temperature sensor firmly onto the heating element, thereby improving temperature measurement accuracy.

[0061] like Figure 12 As shown, the elastic resin part 70 has a limiting groove 702 on the side facing the heating element, and at least a portion of the temperature sensor 80 is located within the limiting groove 702. By providing the limiting groove, the temperature sensor can be better limited and protected.

[0062] The elastic resin component 70 can cover the heating element 400, meaning the size of the elastic resin component is the same as or larger than the heating element. By covering the heating element with the elastic resin component, the heat from the heating element can be isolated, reducing heat transfer to the liquid storage chamber. Therefore, the elastic resin component also serves as heat insulation, further reducing the risk of the liquid in the outlet chamber being heated. In... Figure 6In the preferred embodiment shown, a mica sheet and an elastic resin member 70, serving as heat insulation members 500, are simultaneously provided above the heating element 400. The mica sheet is attached to the upward-facing end face of the heating element 400, and at least a portion of the lower end face of the elastic resin member 70 is attached to the top of the mica sheet. In this way, both the mica sheet and the elastic resin member can isolate the heat of the heating element, providing a double heat insulation effect, allowing more heat to radiate towards the scalp.

[0063] like Figure 6 , Figure 11 As shown, a mounting post 711 extends from the bottom wall of the storage chamber 71. The mounting post 711 has a through hole for assembling the outlet pipe, allowing the outlet pipe to pass through it. The mounting post 711 extends to or below the heating element 400. The heating element 400 has a second through hole 4001, and the mounting post 711 passes through this second through hole. This means the heating element directly contacts the mounting post, not the outlet pipe. The mounting post acts as a heat insulator, preventing the outlet pipe from directly contacting the heating plate and thus avoiding heat transfer from the heating plate to the outlet pipe and then to the storage chamber, further preventing the liquid in the storage chamber from being heated.

[0064] The bottom wall of the cavity 212 has a recessed groove on the outer periphery of the first through hole 2121. A sealing element 90 is installed in the recessed groove. The sealing element 90 is used to seal the gap between the first through hole 2121 and the liquid outlet pipe 72. The lower end face of the mounting post 711 abuts against the sealing element 91. In this way, the mounting post can also serve to fix the sealing element. The multi-functionality of the mounting post effectively simplifies the fixing of the sealing element, and the structural design is ingenious.

[0065] like Figure 2 and Figure 3 As shown, a light panel 600 is also provided in the middle of the comb. The light panel 600 is located between the liquid storage chamber 71 and the heating element 400. The light panel 600 is provided with multiple lamps 6001, which can emit infrared light. The lamps that can emit infrared light are set below the liquid storage chamber. This not only achieves head therapy through red light, but also irradiates the scalp area containing the medicine and the surrounding area with red light while the medicine flows out to the scalp, further promoting the penetration of the medicine and improving hair loss problems.

[0066] The lamp body 6001 is fixed by connecting it to an elastic resin component. The lamp plate 600 is located between the liquid storage chamber 71 and the elastic resin component 70. The elastic resin component 70 has a connecting post 701, and the connecting post 701 has a limiting part 7011. The lamp plate 600 has a third through hole 6002. The limiting part 7011 passes through the third through hole 6002 through a compression deformation assembly method to connect the lamp plate 600. That is, the limiting part plays a role in preventing the lamp plate from detaching from the connecting post. The limiting part can be a snap-fit, bulge, protruding ring, etc., as long as the limiting part is larger than the diameter of the third through hole. By providing a connecting post with a limiting part on the elastic resin component, the lamp plate can be easily fixed, effectively simplifying the assembly structure of the lamp plate.

[0067] Multiple lamp bodies 6001 are distributed around the lamp panel 600. The lamp bodies 6001 are staggered from the heating element 400 in the vertical direction, so that the infrared light avoids the obstruction of the heating element and can shine on the scalp.

[0068] A light-transmitting area 2122 is provided on the bottom wall of the cavity 212, from which light from the lamp body 6001 is emitted. The light-transmitting area 2122 surrounds the outer periphery of multiple liquid outlet pipes 72. A concave surface 2123 is provided on the inner wall of the light-transmitting area 2122 facing the interior of the cavity 212. The light from the lamp body 6001 is focused by the concave surface 2123 and then emitted from the bottom wall of the cavity 212. There are multiple concave surfaces 2123 distributed circumferentially, and their positions are directly aligned vertically with the positions of the multiple lamp bodies 6001. This ensures that the light emitted by each lamp body directly illuminates the concave surface, resulting in better focusing effect. The light emitted by the lamp body 6001 forms a ring around the liquid outlet pipes 72 on the bottom wall of the cavity. The light-transmitting area is set on the bottom wall of the cavity where the liquid-adding component is placed and surrounds the liquid storage tube. A concave surface facing the lamp body is set in the light-transmitting area to effectively focus the light emitted by the lamp body, so that most of the light can hit the scalp and improve the efficiency of the red light acting on the scalp.

[0069] In some embodiments, a heating element 400 and a lamp plate 600 are simultaneously provided below the liquid storage cavity 71. In the vertical direction, the lamp plate 600 is located within the cavity and below the liquid storage cavity, specifically between the liquid storage cavity 71 and the heating element 400. A heat insulation member 500 is connected to the heating element 400 and is located on the side of the heating element 400 facing the liquid storage cavity 71. The massage comb head simultaneously houses the heating element and the lamp plate. When the massage comb is in operation, it can simultaneously activate heating and infrared irradiation functions, which can better promote the absorption of the medication and provide a combing therapy effect. 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 effectively acting on the scalp. Connecting the heat insulation member to the heating element effectively isolates the upward-facing heat, reducing not only the impact of heating on the medication but also the impact of heat radiation from the lamp plate.

[0070] like Figure 3 , Figure 5 and Figure 6 As 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.

[0071] The heat insulation component 500 is connected to the heating element 400 and is located on the upper surface of the heating element 400 facing the lamp panel 600. In this way, the heat insulation effect of the heat insulation component can protect the lamp panel, prevent heat from being transferred to the lamp panel, and protect the lamp panel.

[0072] like Figure 3 As shown, the liquid filling component 7 is located in the middle region X of the comb head 2. The comb teeth and the toothed components that serve as transmission parts are distributed on the outer peripheral region Y of the comb head 2, located outside the liquid filling component 7. There is a hollow section 22 between the middle region X and the outer peripheral region Y. Specifically, the hollow section is an annular hollow ring. That is, an annular hollow area is provided in the head to separate the liquid storage module and heating element from the outer peripheral region. This hollow ring can be used to hang the massage comb on a support with a hook or a support that is compatible with the hollow ring structure or on a wall, so as to facilitate the massage comb to be hung upright. At the same time, the hollow ring can also isolate the heat of the heating element, preventing the heat from being transferred to the outer peripheral region and affecting the components in the outer peripheral region. This ring can be a closed ring or a non-closed ring. The ring is a large semi-circle, leaving a connection area connecting the middle region and the outer peripheral region. The connection area can be used for wiring to connect the electronic components such as the heating element in the middle region to the electronic components in the outer peripheral region or the handheld part.
