[0002] Traditionally, people dye their hair at a barbershop. However, dyeing hair at a barbershop is not only inconvenient but also very expensive. Furthermore, hair dye is mixed manually, which takes a long time. Since dyeing requires professional expertise, dyeing hair at home by non-professionals can result in poor mixing and poor dye quality, with uneven mixing and incomplete dyeing. Consequently, hair dyeing combs have become increasingly popular. These combs contain dye, allowing the dye to be squeezed out while the hair is being combed, making them easy to use.

[0003] Chinese patent CN209547325U discloses a hair dyeing comb, comprising: an upper shell, a delivery channel; at least one liquid storage tank; a hair dyeing comb head, wherein the hair dyeing comb head is arranged on a side surface of the upper shell on which an infusion hole is provided, and a liquid outlet channel connected to the infusion hole is provided on the surface of the hair dyeing comb head, and comb teeth for combing hair are provided on the side surface of the hair dyeing comb head away from the upper shell. When a user needs to use the hair dyeing comb of the present invention to dye their hair, they only need to squeeze the pressing nozzle connected to the squeezing pump to extract the hair dye in the liquid storage tank and deliver it to the hair dyeing comb head for dyeing. This is a simple method, thus meeting the user's need for dyeing hair at home.

[0035] like Figures 1 to 10 The figure shows an embodiment of a household mixing hair dyeing comb of the present invention, which includes a first shell 100 and a second shell 200. The first shell 100 is connected to a comb head 300 with a plurality of infusion holes 310 on one side surface. The first shell 100 and the second shell 200 are coaxially detachably connected. The first shell 100 has a first liquid storage tank 400 built in, and the second shell 200 has a second liquid storage tank 500 built in. The first liquid storage tank 400 and the second liquid storage tank 500 are connected to a mixer 600, and the mixer 600 is connected to the infusion holes 310. A pressing component 700 is connected between the first liquid storage tank 400 and the second liquid storage tank 500 for pressing and squeezing out the liquid in the first liquid storage tank 400 and the second liquid storage tank 500 at the same time.

[0036] During implementation of this embodiment, the first housing 100 and the second housing 200 are coaxially and vertically connected, and the first liquid reservoir 400 and the second liquid reservoir 500 are correspondingly coaxially and vertically connected. When the pressing assembly 700 is actuated, the liquids in the first and second liquid reservoirs 400 and 500 are simultaneously extruded into the mixer 600 for remixing. The mixed liquids then flow out through the infusion hole 310 of the combing head 300. This allows the user to dye their hair while combing their hair 300, simplifying the operation. The vertical arrangement of the first and second liquid reservoirs 400 and 500 of the present invention effectively solves the problem of uncomfortable grip of the hair dyeing comb, providing a natural and comfortable grip and improving the user experience.

[0037] In one embodiment, the first shell 100 is provided with an opening 110, and a slide rail 120 is provided at the opening 110. The two sides of the combing head 300 are provided with a slide groove 320 that is slidably connected to the slide rail 120. It should be noted that the slide groove 320 is not only provided on both sides of the combing head 300, but also can be provided on the top of the combing head 300. The slide rail 120 is provided on the three sides of the opening 110. The slide groove 320 is slidably connected to the slide rail 120 one by one.

A pressing block abuts the lower edge of the first snap-fit portion 130, one end of which is connected to the second housing 200. During installation, the pressing block is pressed, and the two sets of second and first clamping portions 130 retract into the interior of the second housing 200, allowing the first housing 100 and the second housing 200 to be quickly separated. During installation, the first clamping portions 130 are squeezed and retracted into the second housing 200. When the first housing 100 and the second housing 200 are in abutment and alignment, the first clamping portions 130 spring into the third clamping slots 220, completing the installation of the first housing 100 and the second housing 200. In this embodiment, the first housing 100 and the second housing 200 can be made of a metal material with good ductility.

[0039] In one embodiment, a first extrusion pump 800 is provided at the outlet of the first liquid storage tank 400, and a second extrusion pump 900 is provided at the outlet of the second liquid storage tank 500. The first extrusion pump 800 is connected to a first connecting pipe 810 that can extend into the bottom of the first liquid storage tank 400, and the second extrusion pump 900 is connected to a second connecting pipe 910 that can extend into the bottom of the second liquid storage tank 500. The pressing assembly 700 is connected between the first extrusion pump 800 and the second extrusion pump 900. During implementation, the first extrusion pump 800 and the second extrusion pump 900 can discharge liquid by being squeezed, which is easy to operate. The first connecting pipe 810 and the second connecting pipe 910 extend into the bottom of the first liquid storage tank 400 and the second liquid storage tank 500, respectively, and can suck out the liquid at the bottom of the first liquid storage tank 400 and the second liquid storage tank 500.

[0040] In one embodiment, the pressing assembly 700 includes a first connecting plate 710, a second connecting plate 720, a pressing member 730, a discharge assembly 740, and a second storage bin 750:

[0041] The first connecting plate 710 is mounted on the end of the first liquid storage tank 400, the second connecting plate 720 is mounted on the end of the second liquid storage tank 500, the discharge assembly 740 is connected between the first connecting plate 710 and the second connecting plate 720, one end of the pressing member 730 is hinged to the discharge assembly 740, and the other end of the pressing member 730 extends out of the first housing 100, and the second storage bin 750 is movably connected to the discharge assembly 740;

[0042] The discharge assembly 740 is provided with a first storage bin 746 coaxially arranged with the second storage bin 750. The first storage bin 746 and the second storage bin 750 are respectively connected to the first extrusion pump 800 and the second extrusion pump 900. The first storage bin 746 and the second storage bin 750 are connected to the two interfaces of the tee pipe 760, and the other interface of the tee pipe 760 is connected to the mixer 600.

[0043] In this embodiment, the first connecting plate 710, the second connecting plate 720 and the discharge assembly 740 can be connected as a whole, the first squeezing pump 800 squeezes the liquid into the first storage bin 746, and the second squeezing pump 900 squeezes the liquid into the second storage bin 750, and then flows into the mixer 600 through the three-way pipe 760 for mixing. Among them, when the hair dye comb is placed vertically, the two interfaces of the three-way pipe 760 are arranged horizontally, and the other interface is arranged vertically. The second shell 200 is provided with a groove at a position opposite to the other interface. When the first shell 100 and the second shell 200 are matched and installed, the groove plays a positioning role for the other interface. In addition, in this embodiment, since the second storage bin 750 is movably connected to the storage assembly, in order to facilitate the linkage of related components caused by the pressing action, the three-way pipe 760 of this embodiment adopts a hose.

[0044] In one embodiment, the first connecting plate 710 includes a first connecting portion 711 and a positioning portion 712 coaxially connected. The first connecting portion 711 is rotatably connected to the first liquid storage tank 400, and the discharge assembly 740 is coaxially movably connected to the positioning portion 712. The first liquid storage tank 400 is provided with a first flange 410 on the outer periphery of the end portion, and a first retaining edge 713 is provided on the outer edge of the first connecting portion 711. The first flange 410 is inserted into the first retaining edge 713, and the first liquid storage tank 400 is rotatably connected to the first connecting plate 710. The central angle of the first retaining edge 713 can be set to be slightly larger than 180°, so that the first connecting plate 710 can be pushed in from the side of the first liquid storage tank 400. Furthermore, the first connecting portion 711 is provided with a first hole and a second hole 715, which are interconnected. The second hole 715 is coaxial with the first connecting portion 711. The centerline of the first hole is offset from the central axis of the first connecting portion 711 and is located on the side facing away from the first retaining edge 713. The diameter of the first hole is slightly larger than the diameter of the first extrusion pump 800, allowing the first extrusion pump 800 to slide smoothly into the second hole 715 within the first hole. When installing the first liquid storage tank 400, the first extrusion pump 800 is first inserted into the first hole, and then the first connecting portion 711 is pushed until the first retaining edge 713 fully engages with the first flange 410, allowing the first extrusion pump 800 to enter the second hole 715 and become coaxial with the second hole 715. In this embodiment, the positioning portion 712 is integrally formed with the first connecting portion 711 and coaxially disposed. The diameter of the positioning portion 712 is smaller than that of the first connecting portion 711. The positioning portion 712 is provided with two sets of pivot points 716 on its outer periphery, which abut against the pressing member 730. These pivot points 716 are located at either end of the diameter of the positioning portion 712. A movable groove 717 is defined below the pivot points 716, and the second storage bin 750 is provided with a movable portion 751 that is movably connected to the movable groove 717. Furthermore, a long groove 718 is defined on the side of the positioning portion 712 to accommodate a tee pipe 760, resulting in a compact structure.

[0045] In one embodiment, the second connecting plate 720 includes a second connecting portion 721, a clamping portion 722 and a positioning boss 723 provided on the second connecting portion 721. The outer edge of the discharge assembly 740 is provided with a first clamping groove that engages with the clamping portion 722, and the interior of the second housing 200 is provided with a positioning step that matches the positioning boss 723. The second connecting portion 721 is rotatably connected to the second liquid storage tank 500. The outer periphery of the end of the second liquid storage tank 500 is provided with a second flange 510. The outer edge of the second connecting portion 721 is provided with a second clamping edge 724. The second flange 510 is clamped into the second clamping edge 724, and the second liquid storage tank 500 is rotatably connected to the second connecting plate 720. The central angle of the second clamping edge 724 can be set to be slightly larger than 180 degrees, so that the second connecting plate 720 can be pushed in from the side of the second liquid storage tank 500. Furthermore, the second connecting portion 721 is provided with a third hole and a fourth hole 726 that are interconnected. The fourth hole 726 is coaxial with the second connecting portion 721. The centerline of the third hole is offset from the central axis of the second connecting portion 721 and is located on the side facing away from the second retaining edge 724. The diameter of the third hole is slightly larger than the diameter of the second extrusion pump 900, allowing the second extrusion pump 900 to slide smoothly into the fourth hole 726 within the second hole 715. When installing the second liquid storage tank 500, the second extrusion pump 900 is first inserted into the third hole. The second connecting portion 721 is then pushed until the second retaining edge 724 fully engages the second flange 510, allowing the second extrusion pump 900 to enter the fourth hole 726 and become coaxial with the fourth hole 726. In this embodiment, a positioning boss 723 is provided on the outer edge of the second connecting portion 721. When the second liquid storage tank 500 is installed in the second housing 200, the positioning boss 723 cooperates with the positioning step to position the second liquid storage tank 500. Among them, the positioning bosses 723 can be set as two groups, and the two groups of bosses are located on two different outer peripheral surfaces above and below the second connecting part 721. In this way, the cooperation between the positioning bosses 723 and the positioning steps can play a good role in axial positioning and circumferential positioning.

[0046] In one embodiment, the discharge assembly 740 includes a positioning plate, a support rod, and a hinge shaft provided at the end of the support rod. The support rod is connected to the positioning plate, and one end of the pressing member 730 is hinged to the hinge shaft. Pressing the pressing member 730 causes the first connecting plate 710 and the first liquid storage tank 400 to descend simultaneously, and the second connecting plate 720 and the second liquid storage tank 500 to lift upward simultaneously. Specifically, the first card slot of the discharge assembly 740 is specifically provided at the edge of the positioning plate, and a concave cavity matching the positioning plate is provided on the upper portion of the second connecting portion 721. The number of the card portions 722 and the first card slots is equal, and the card portions 722 and the first card slots are evenly distributed. During installation, the positioning plate can be stably installed in the concave cavity by aligning the card portion 722 with the first card slot and rotating the positioning plate. In addition, in this embodiment, a positioning groove is provided on the positioning disk, and a positioning block 727 is provided on the second connecting disk 720. When the clamping portion 722 is aligned with the first clamping groove, the positioning block 727 is snapped into one end of the positioning groove. The positioning disk is rotated, and the positioning block 727 slides relative to the positioning groove to the other end of the positioning groove, completing the connection between the second connecting disk 720 and the positioning disk. It can be seen that the setting of the positioning block 727 and the positioning groove plays a guiding and locking role in the rotation of the positioning disk. In this embodiment, there are two groups of support rods, and the two groups of support rods are symmetrically arranged on both sides of the three-way pipe 760. There are also two groups of hinge shafts, and the two groups of hinge shafts are respectively located at the ends of the two groups of support rods. After the first connecting disk 710 and the discharge assembly 740 are installed, the two groups of support rods are just located on both sides of the long groove 718. In addition, the positioning disk is also provided with a hole groove that can accommodate the movement of the second storage bin 750.

[0047] In one embodiment, the pressing member 730 includes a connecting rod 731, a button 732, and a connecting piece 733. One end of the connecting rod 731 is hinged to the discharge assembly 740, and the connecting piece 733 is connected to the other end of the connecting rod 731. The button 732 is located on the side of the connecting piece 733 away from the connecting rod 731. The connecting rods 731 are divided into two groups, and the ends of the two groups of connecting rods 731 are respectively provided with hinge holes 734 that are hinged to the hinge axis. To facilitate the pressing operation, the second housing 200 is provided with a slot 250 that allows the button 732 to move up and down. The connection piece 733 is arranged so that when the button 732 moves within the slot 250, the connection piece 733 can cover the slot 250, ensuring an aesthetically pleasing appearance. In addition, in order to facilitate the pressing operation, the button 732 of this embodiment can be provided with an arc surface that fits the user's finger and a rolling pattern can be provided on the arc surface to increase friction. Of course, this is only a preference made to increase the convenience of operation and is not a restrictive provision of the present invention. When the button 732 is pressed, the connecting rod 731 rotates downward with the hinge axis as the center: the fulcrum 716 applies a downward force to the first connecting disk 710, the first connecting disk 710 and the first storage tank move downward at the same time, the first storage bin 746 and the first extrusion pump 800 squeeze each other, the first extrusion pump 800 squeezes the liquid in the first storage tank, and the liquid passes through the first storage bin 746 and the three-way pipe 760 and then flows into the mixer 600; at the same time, driven by the support rod, since the positioning disk and the second connecting disk 720 are engaged together, the support rod is lifted upward, driving the positioning disk and the second connecting disk 720 to be lifted upward, the second storage bin 750 moves downward relative to the positioning disk, the second storage bin 750 and the second extrusion pump 900 squeeze each other, the second extrusion pump 900 squeezes the liquid in the second storage tank, and the liquid passes through the second storage bin 750 and the three-way pipe 760 and then flows into the mixer 600. In this embodiment, the positions and sizes of the connecting rod 731, the fulcrum 716, the hinge shaft and the support rod can be set to ensure that the displacements of the first extrusion pump 800 and the second extrusion pump 900 are equal each time they squeeze, so that the volumes of liquid discharged by the first extrusion pump 800 and the second extrusion pump 900 are equal each time they press, thereby achieving the same proportional quantitative liquid discharge of the first extrusion pump 800 and the second extrusion pump 900, which helps to achieve good hair dyeing effects.

[0048] In one embodiment, the mixer 600 includes a liquid inlet 610, a plurality of mixing units 620, a liquid outlet 630, and a liquid inlet port 310. The inlet 610, the plurality of mixing units 620, the liquid outlet 630, and the liquid inlet port 310 are sequentially connected, and the plurality of mixing units 620 are evenly spaced. The inlet 610, the plurality of mixing units 620, and the liquid outlet 630 are all located within the housing. Liquid flowing in through the tee pipe 760 flows into the liquid inlet 610, is mixed by the plurality of mixing units 620, and then flows out of the liquid outlet 630. During this process, the plurality of mixing units 620 mix the liquids squeezed from the first and second liquid reservoirs 400, 500, multiple times, achieving a uniform mixing effect. This results in long-lasting hair coloring that is less prone to fading, providing the user with a better user experience. In this embodiment, the mixer 600 is located on the side of the comb 300, concealed within the first housing 100, so as not to affect the product's appearance.

[0049] In one embodiment, the mixing unit 620 includes a V-shaped rod 621 and two sets of straight rods 622, which form a diamond-shaped structure. The axis of the V-shaped rod 621 coincides with the axis of the liquid inlet 610, and the two sets of straight rods 622 are symmetrically arranged on either side of the axis of the V-shaped rod 621. The ends of the V-shaped rod 621 and the two sets of straight rods 622 respectively abut the inner walls of the housing on opposite sides. After the two liquids flow into the liquid inlet 610, they are separated into two streams at the tip of the V-shaped rod 621. A first notch 623 is provided between the V-shaped rod 621 and the two sets of straight rods 622, and a second notch 624 is provided between the two sets of straight rods 622. The two streams of liquid flow into the diamond-shaped structure through the first notch 623 and merge, then flow out through the second notch 624. After passing through multiple mixing units 620, the liquids are separated, combined, and mixed multiple times to achieve uniform mixing.
