Description

Technical Field

[0001] This utility model relates to the field of beauty tool technology, specifically a contact-type gray hair dyeing device. Background Technology

[0002] With the aging population and increasing life pressures, the gray hair population is showing a trend towards younger ages, and the market size of home hair dyeing is growing annually due to its convenience and privacy. However, existing hair dyeing tools have serious drawbacks: brush-like brush heads cause dye to seep into the hairline, solid dyes require repeated application and do not completely cover the hair roots, and during operation, dye seeps down the hair strands to the scalp, causing contact dermatitis.

[0003] Existing technologies have attempted improvements, but have failed to overcome the core contradiction between "dye contact with the scalp" and "long-lasting, even release." Current technologies have not effectively addressed the three major problems of scalp contamination, uneven coloring, and short processing time. Therefore, there is an urgent need to develop a hair dyeing tool that provides even coloring without scalp staining, meeting the needs of frequent at-home hair dyeing. Utility Model Content

[0004] To overcome the problems existing in the related technologies, this application provides a contact hair dyeing device for gray hair, which provides even coloring, prevents scalp contamination, is highly durable, and is suitable for home self-service partial gray hair dyeing, especially for delicate areas such as the hairline and sideburns.

[0005] This application provides a contact-type gray hair dye, including a receiving cavity, a cavity protective cover that is closable and connected to the top of the receiving cavity, and an adsorption area disposed on the upper part of the receiving cavity. The adsorption area includes a flexible binding surface, a first adsorption rod, a second adsorption rod, a plurality of umbrella-shaped contact units, and a hollow mesh base fixed to the lower end of the binding surface. The first and second adsorption rods are both adsorption sponges. The top surface of the contact unit is smooth and extends circumferentially to form an umbrella-shaped structure. The contact units are spaced apart on the upper part of the binding surface.

[0006] The core structure of the contact-type gray hair dyer is defined to achieve precise contact dyeing and avoid large-area contact of the dye with the scalp.

[0007] Preferably, the top of the first adsorption rod is lower than the eaves of the contact unit, and the first adsorption rods are staggered between the contact units; the top of the second adsorption rod is flush with the upper surface of the base, and the second adsorption rod penetrates vertically through the hollow part of the base.

[0008] The first adsorption rods are staggered and positioned below the eaves to prevent excessive seepage of hair dye; the second adsorption rod penetrates the base and is directly connected to the hair dye source to ensure a continuous supply. The eaves isolate the scalp, and the height difference prevents side spillage of the dye, reducing the contamination rate.

[0009] Preferably, the hollow portion of the base is a honeycomb structure with multiple apertures, and the inner wall of the honeycomb is provided with a flow guide groove.

[0010] Preferably, the receiving cavity includes a flow cavity and a detachable replacement cavity, wherein the replacement cavity is connected to the tail of the flow cavity by mutually cooperating snaps.

[0011] The detachable and replaceable cavity allows for convenient replacement of hair dye, while the snap-fit ​​connection ensures sealing and stability, preventing deterioration caused by pre-mixing of the dye solution and extending the duration of dye activity.

[0012] Preferably, the replacement cavity includes a bottom cover, a cavity shell, a cavity core, and a spring. The cavity core is disposed inside the cavity shell, and the bottom cover is fixed to the spring and snapped into the cavity shell through a protrusion structure, so that the spring presses the cavity core into the cavity shell.

[0013] Spring compression ensures full contact between the core and the flow chamber, resulting in more uniform dyeing. Both the core and the entire replacement chamber are replaceable.

[0014] Preferably, the flow cavity is provided with a flow channel extending to the hollow part of the base, and the outlet end of the flow channel is aligned with the central axis of the second adsorption rod.

[0015] The flow channel precisely delivers the hair dye to the second adsorption rod, reducing waste and improving penetration efficiency. The dye solution reaches the core of the adsorption rod directly, reducing residue and increasing dye utilization.

[0016] Preferably, the edge of the binding surface extends to form an annular fixing edge that covers the bottom periphery of the receiving cavity, and the inner wall of the annular fixing edge is provided with a wavy pleated layer.

[0017] The wavy, pleated layer provides elastic cushioning to adapt to changes in head pressure; the interference fit structure ensures a tight connection between the adsorption area and the containment cavity, preventing leakage.

[0018] Preferably, the corrugated layer forms an interference fit elastic covering structure with the bottom outer wall of the receiving cavity. The corrugated layer provides elastic cushioning to adapt to changes in head pressure; the interference fit structure ensures a tight connection between the adsorption area and the receiving cavity, preventing leakage.

[0019] Preferably, the bottom of the umbrella eave of the contact unit is provided with radially distributed microporous channels, the microporous channels extending through the thickness direction of the umbrella eave, and the density of the microporous channels decreasing from the center of the umbrella eave to the edge.

[0020] The stepped microporous channels and the contact unit eaves better reduce the pressure on the scalp, and the stepped dye seeps out from the microporous channels, resulting in uniform coloring.

[0021] Preferably, the cavity protective cover includes an outer cover and a cap-shaped inner cover, the inner cover having a moist sponge at the top inner end, and the edge of the cap having an annular sealing ring that protrudes inward.

[0022] The double-layer protective cap (outer and inner caps) prevents dust and dryness, the moist sponge maintains the humidity of the adsorption area, and the sealing ring blocks air from entering, thus prolonging the activity of the hair dye.

[0023] The technical solution provided in this application has the following beneficial effects:

[0024] (1) The umbrella brim physically isolates the scalp to prevent scalp contamination;

[0025] (2) Radial micropore channels achieve uniform coloring from the hair root to the hair tip;

[0026] (3) The elastic sealing structure allows for longer storage time when inverted;

[0027] (4) The dye solution can be replaced and reused, making it highly practical.

The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0039] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0040] To address the aforementioned issues, this application provides a lamp clamping device that is easy to install, more adaptable, and suitable for mounting surfaces of various shapes and materials. It is particularly convenient for lamps that require frequent changes in position or angle, and offers a high level of safety.

[0041] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0042] Referring to Figures 1 to 6, a contact-type gray hair dye includes a receiving cavity 1, a cavity protective cover 3 that is closable and connected to the top of the receiving cavity 1, and an adsorption area 2 disposed on the upper part of the receiving cavity 1. The adsorption area 2 includes a flexible binding surface 23, a first adsorption rod 21, a second adsorption rod 22, a plurality of umbrella-shaped contact units 24, and a hollow mesh base 25 fixed to the lower end of the binding surface 23. The first adsorption rod 21 and the second adsorption rod 22 are both adsorption sponges. The top surface of the contact unit 24 is smooth and extends circumferentially to form an umbrella structure. The contact units 24 are spaced apart on the upper end of the binding surface 23.

[0043] In the specific implementation process, open the cavity protective cover 3, align the adsorption area 2 with the gray hair area and press it; the umbrella structure of the contact unit 24 isolates non-target areas, and the hair dye seeps into the hair strands through the adsorption rod. The umbrella-shaped contact unit 24 disperses the pressure of the hair, the flexible binding surface 23 conforms to the curve of the head, and the hollow base 25 supports the adsorption structure and guides the flow of the hair dye.

[0044] The top of the first adsorption rod 21 is lower than the eaves of the contact unit 24, and the first adsorption rods 21 are staggered between the contact units 24; the top of the second adsorption rod 22 is flush with the upper surface of the base, and the second adsorption rod 22 penetrates vertically through the hollow part of the base 25.

[0045] In the basic hair dyeing process, the contact unit 24 of the contact-type gray hair dyer is pressed onto the gray hair area. The umbrella-shaped design conforms to the head shape to form an isolation zone. The hair squeezes the microporous channels to adaptively release the dye. The first adsorption rod 21 quickly covers the hair roots, while the second adsorption rod 22 slowly replenishes the dye. This achieves even coloring from the roots to the ends of the hair, with zero staining on the scalp.

[0046] The hollow portion of the base 25 is a honeycomb 251 with multi-level apertures, and the inner wall of the honeycomb 251 is provided with a flow guide groove 252.

[0047] During implementation, the hair dye flows in layers through the honeycomb holes 251, and the guide channel 252 directs it to the center of the second adsorption rod 22. This disperses scalp pressure, improves comfort, and enhances the fit.

[0048] The receiving cavity 1 includes a flow cavity 11 and a detachable replacement cavity 12, wherein the replacement cavity 12 is connected to the tail of the flow cavity 11 by mutually cooperating buckles 121.

[0049] In the specific implementation process, the dye replacement operation is carried out in a cavity consisting of a flow cavity 11 and a replacement cavity 12, which are connected by a snap-fit ​​mechanism. When replacing the dye, the replacement cavity is pressed until a "click" sound indicates that the snap-fit ​​is locked, which can quickly complete the replacement and improve the dye utilization rate.

[0050] The replacement cavity includes a bottom cover 4, a cavity shell 5, a cavity core 6, and a spring 7. The cavity core 6 is located inside the cavity shell 5. The bottom cover 4 is fixed to the spring 7 and is snapped into the cavity shell 5 through a protrusion structure, so that the spring 7 presses the cavity core 6 into the cavity shell 5.

[0051] The spring 7, when compressed, generates a restoring force, pushing the cavity core 6 towards the top of the cavity shell 5 until the cavity core 6 is fully abutted against the inner wall of the cavity shell 5; the protruding structure locks the bottom cover 4 and the cavity shell 5, forming a closed cavity. Both the cavity core and the entire replacement cavity are replaceable, allowing for greater dye conservation. When dye needs to be replenished, the cavity core can be replaced directly; when the dye color needs to be changed, the entire replacement cavity can be replaced, offering diverse options.

[0052] The flow cavity 11 is provided with a flow channel 111 extending to the hollow part of the base 25, and the outlet end of the flow channel 111 is aligned with the central axis of the second adsorption rod 22.

[0053] In the specific implementation process, the dye liquor is directly injected into the core of the second adsorption rod 22 through the guide channel 111, and the guide groove guides the flow of dye liquors of different viscosities.

[0054] The edge of the binding surface 23 extends to form an annular fixing edge that covers the bottom periphery of the receiving cavity 1, and the inner wall of the annular fixing edge is provided with a wavy pleated layer 231.

[0055] In the specific implementation process, the annular fixed edge of the binding surface 23 wraps around the bottom of the cavity, and the pleated layer 231 rebounds and seals after being deformed by pressure, and the wavy pleated layer achieves elastic sealing.

[0056] The wavy pleated layer 231 forms an interference fit elastic covering structure with the bottom outer wall of the receiving cavity 1.

[0057] For long-term storage and maintenance during implementation, the cavity protective cover includes an outer cover and a cap-shaped inner cover. The inner cover has an inwardly protruding annular sealing ring at the edge of the cap. The edge of the binding surface extends to form an annular fixing edge, and the inner wall has a wavy pleated layer that forms an interference fit with the bottom of the receiving cavity. When stored upside down, the protruding sealing ring prevents air intrusion, and the moist sponge in the inner cover maintains the humidity of the cavity.

[0058] The bottom of the umbrella eave of the contact unit 24 is provided with radially distributed microporous channels 241. The microporous channels 241 penetrate through the thickness direction of the umbrella eave, and the density of the microporous channels 241 decreases from the center of the umbrella eave to the edge.

[0059] In the specific implementation process, only the microporous channels in the overall structure of the contact unit 24 contain hair dye. While achieving physical isolation of the scalp, it can also achieve uniform hair dyeing. The radially distributed microporous channels 241 realize the gradient release of hair dye (more in the center and less at the edges), avoiding excessive skin contamination at the edges. The microporous channels 241 alleviate the deformation pressure of the contact unit and improve its durability.

[0060] The cavity protective cover includes an outer cover 31 and a cap-shaped inner cover 32. The inner cover has a moist sponge 33 at the top inner end and an annular sealing ring 34 protruding inward at the edge of the cap.

[0061] In practical implementation, the container can be stored upside down. When the protective cover is closed, the sealing ring 34 presses against the top of the receiving cavity 1, and the moist sponge 33 contacts the adsorption area 2. The moist sponge 33 maintains the sponge's moisture content, thus solving the problem of the fiber rod (first adsorption rod 21) drying out.

[0062] The technical solution provided in this application is:

[0063] 1. By isolating gray hair areas through umbrella-shaped contact units and combining dual adsorption rods to supply hair dye in stages, precise dyeing is achieved with zero skin contamination.

[0064] 2. The detachable and replaceable cavity works in conjunction with the flow channel to support quick replacement and efficient delivery of hair dye;

[0065] 3. The double-layer protective cap has a built-in moist sponge and sealing ring to block air and maintain the activity of the hair dye.

[0066] Technical effects:

[0067] 1. Solves the problems of traditional hair dyes easily staining the skin and being cumbersome to use;

[0068] 2. The flexible binding surface and wave-like pleats improve the fit of the head;

[0069] 3. The honeycomb base and microporous channels optimize the flow efficiency of hair dye and reduce waste.

[0070] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
