Description

Technical Field

[0001] This utility model relates to the field of nursing care products technology, specifically a temperature-sensitive color-changing multifunctional bath brush. Background Technology

[0002] In people's daily cleaning and grooming processes, tools such as face brushes, body brushes, and shampoo brushes are very popular. They can better clean the skin and hair, promote blood circulation, remove dead skin cells, massage and relax, and help clean hard-to-reach areas.

[0003] However, existing bathing tools have many shortcomings. On the one hand, they cannot provide intuitive feedback on water temperature, requiring users to use a thermometer or manually test the temperature, which is cumbersome and poses a risk of scalding, especially for children, making them unsuitable for use. On the other hand, in terms of materials, bath brushes made of hard materials (such as plastic and nylon) can easily scratch the skin; while ordinary soft rubber brushes lack functional innovation and offer a limited user experience.

[0004] Currently, existing thermochromic materials are mostly used in industrial or decorative fields, and have not yet been combined with bathing tools to achieve real-time visual monitoring of water temperature. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a temperature-sensitive color-changing multifunctional bath brush.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] Thermosensitive color-changing layer, base plate, and brush area disposed on the surface of the base plate, wherein the thermosensitive color-changing layer is disposed on the surface of the base plate or the brush area, or disposed in the base plate interlayer;

[0008] The base plate has a first plate surface and a second plate surface on its two sides;

[0009] The first board surface is provided with a first brush area and a second brush area. The first brush area is located at the center of the first board surface, and multiple second brush areas are provided, with multiple second brush areas located around the first brush area.

[0010] The second plate surface is provided with a third bristle area and a fourth bristle area. The third bristle area is located at the center of the second plate surface, and multiple fourth bristle areas are provided, with multiple fourth bristle areas located around the third bristle area.

[0011] The surfaces of the first bristle area and the third bristle area are provided with a temperature-sensitive color-changing layer.

[0012] Main working principle: This temperature-sensitive color-changing multifunctional bath brush includes a temperature-sensitive color-changing layer, a base plate, and bristle areas disposed on the surface of the base plate. The temperature-sensitive color-changing layer is disposed on the surface of the base plate or the bristle areas, or disposed within a layer of the base plate. The two sides of the base plate constitute a first surface and a second surface, respectively. This double-sided design gives the bath brush more diverse functions and adaptability to various scenarios. On the first surface, a first bristle area is located in the center, surrounded by multiple second bristle areas; similarly, the second surface has a third bristle area in the center, surrounded by multiple fourth bristle areas. The rational layout of each bristle area ensures the overall balance and stability of the bath brush while meeting the cleaning needs of different parts and methods.

[0013] The first and third brush areas have a thermochromic layer sandwiched between their surfaces or base plates. This thermochromic layer is crucial for enabling the bath brush's water temperature feedback function. The thermochromic layer uses microencapsulated reversible thermochromic substances, also known as reversible thermochromic pigments (commonly called thermochromic pigments, temperature-sensitive powders, or thermochromic powders). The reversible thermochromic pigment particles are spherical, with an average diameter of 2-7 micrometers. They contain the color-changing substance and are encased in a transparent shell approximately 0.2-0.5 micrometers thick. This transparent shell is neither soluble nor melted, playing a vital protective role by effectively preventing the color-changing substance from being corroded by other chemicals, ensuring the pigment maintains its color-changing function stably under various usage conditions.

[0014] When a bath brush is immersed in water, the reversible thermochromic pigment changes color depending on the water temperature. This is because the color-changing substances within the pigment have a specific molecular structure. Under different temperature conditions, the thermal motion of the molecules changes, leading to changes in the interactions and arrangement between molecules. This, in turn, alters the pigment's light absorption and reflection properties, ultimately resulting in different colors. For example, at lower temperatures, the pigment may exhibit one color; as the temperature rises to a certain level, the pigment rapidly transforms into another color.

[0015] When using the bath brush, users can intuitively understand the water temperature by observing the color changes of the temperature-sensitive color-changing layer on the surface of the first and third bristle areas. This real-time and intuitive water temperature feedback mechanism avoids the cumbersome operation of using an additional thermometer or manually testing the temperature, greatly reducing the risk of scalding, and providing safer bathing protection, especially for children.

[0016] In summary, the temperature-sensitive color-changing multifunctional bath brush, through its unique structural design and ingenious application of the temperature-sensitive color-changing layer, utilizes the properties of reversible temperature-sensitive color-changing pigments to achieve real-time visual monitoring of water temperature, bringing users a safer and more convenient bathing experience.

[0017] Preferably, the second bristle area and / or the fourth bristle area are provided with one or more temperature-sensitive color-changing bristle units.

[0018] Preferably, the first plate surface and / or the second plate surface are covered with a thermosensitive color-changing protective layer.

[0019] Preferably, the number of the second bristle area and the fourth bristle area are equal, and each second bristle area corresponds one-to-one with each fourth bristle area.

[0020] Preferably, there are five of each of the second and fourth bristle areas, with the five second bristle areas and the five fourth bristle areas forming a pentagram shape.

[0021] Preferably, the first bristle area is provided with a plurality of first bristle units, and the plurality of first bristle units are radially distributed with the center of the first plate surface as the origin.

[0022] Each of the second bristle areas is provided with a plurality of second bristle units, which are evenly distributed in the second bristle area.

[0023] Preferably, the first bristle unit is a pyramid, and the second bristle unit is an arc-shaped protrusion.

[0024] Preferably, the distance between the end face of the first bristle unit and the first plate surface is greater than the distance between the end face of the second bristle unit and the first plate surface.

[0025] Preferably, a hanging ring is provided on one side of the base plate.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] This invention features a thermosensitive color-changing layer on the surfaces of the first and third bristle areas, employing microencapsulated reversible thermochromic pigments. When the bath brush comes into contact with water, the pigments rapidly change color with the water temperature. Users can easily and intuitively understand the water temperature by simply observing the color change of the bristle areas with the naked eye, without the need for additional tools.

[0028] It avoids the cumbersome operation of traditional bathing tools that require the use of a thermometer or manual temperature testing, greatly reducing the risk of burns caused by inconvenience or misjudgment. It is especially suitable for children, the elderly and other people who are sensitive to water temperature, thus improving the safety of the bathing process.

[0029] Meanwhile, the first panel has a first bristle area and multiple second bristle areas, while the second panel has a third bristle area and multiple fourth bristle areas. This partitioned layout gives the bath brush more functions. The first and third bristle areas can be used for targeted cleaning and massage, while the multiple second and fourth bristle areas can expand the cleaning area to meet the cleaning needs of different parts of the body.

Detailed Implementation

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] Example 1

[0039] This embodiment discloses a temperature-sensitive, color-changing, multifunctional bath brush, such as... Figures 1-4 As shown, the temperature-sensitive color-changing multi-functional bath brush uses a base plate 1 as its core support structure. The two sides of the base plate 1 form the first surface 2 and the second surface 3, respectively. This double-sided design gives the bath brush more diverse functions and adaptability to different scenarios. On the first surface 2, a first bristle area 20 is located in the center, surrounded by multiple second bristle areas 21. Similarly, on the second surface 3, a third bristle area 30 is located in the center, surrounded by multiple fourth bristle areas 31. This rational layout of the bristle areas ensures both the overall balance and stability of the bath brush, while also meeting the cleaning needs of different areas and methods.

[0040] A thermosensitive color-changing layer 5 is provided between the surface or base plate 1 of the first bristle area 20 and the third bristle area 30. This thermosensitive color-changing layer 5 is the key to realizing the water temperature feedback function of the bath brush. The thermosensitive color-changing layer 5 uses microencapsulated reversible thermosensitive color-changing material, namely reversible thermosensitive color-changing pigment (commonly known as thermochromic pigment, temperature-sensitive powder, or thermochromic powder). The particles of the reversible thermosensitive color-changing pigment are spherical with an average diameter of 2-micrometers. They contain color-changing material inside and are wrapped with a transparent shell with a thickness of 0.2-0.1 micrometers. This transparent shell cannot dissolve or melt, and it plays a crucial protective role, effectively preventing the color-changing material from being corroded by other chemicals and ensuring that the pigment can stably perform its color-changing function under various usage environments.

[0041] When a bath brush is immersed in water, the reversible thermochromic pigment changes color depending on the water temperature. This is because the color-changing substances within the pigment have a specific molecular structure. Under different temperature conditions, the thermal motion of the molecules changes, leading to changes in the interactions and arrangement between molecules. This, in turn, alters the pigment's light absorption and reflection properties, ultimately resulting in different colors. For example, at lower temperatures, the pigment may exhibit one color; as the temperature rises to a certain level, the pigment rapidly transforms into another color.

[0042] When using the bath brush, users can intuitively understand the water temperature by observing the color changes of the temperature-sensitive color-changing layer 5 on the surface of the first bristle area 20 and the third bristle area 30. This real-time and intuitive water temperature feedback mechanism avoids the cumbersome operation of using a thermometer or manually testing the temperature, greatly reducing the risk of scalding, and providing safer bathing protection, especially for children.

[0043] In summary, the temperature-sensitive color-changing multifunctional bath brush, through its unique structural design and ingenious application of the temperature-sensitive color-changing layer 5, utilizes the characteristics of reversible temperature-sensitive color-changing pigments to achieve real-time visual monitoring of water temperature, bringing users a safer and more convenient bathing experience.

[0044] In some optional embodiments, some bristles in the second bristle area 21 and the fourth bristle area 31 are made into thermosensitive color-changing bristle units 6. These thermosensitive color-changing bristle units 6 are made of special thermosensitive color-changing fiber material, mixed with ordinary bristles and woven into the second bristle area 21 or the fourth bristle area 31, or both the second bristle area 21 and the fourth bristle area 31. During bathing, when the bristles come into contact with skin or water of different temperatures, the thermosensitive color-changing bristle units 6 will change color according to the temperature change. This not only increases the fun of bathing, but also allows users to more intuitively feel the temperature differences of different parts of the body, or judge the distribution of water temperature on the bristles.

[0045] In some optional embodiments, a thermochromic protective layer 7 is applied to the surface of the first plate 2 or the second plate 3, or the first plate 2 and the second plate 3. This protective layer is uniformly applied to the plate surface through a coating process. When the entire bath brush is in different temperature environments, the thermochromic protective layer 7 can also provide a certain degree of protection for the base plate 1, preventing the thermochromic layer 5 from being scratched or worn.

[0046] In some optional embodiments, the number of second bristle areas 21 and fourth bristle areas 31 is precisely designed during the manufacture of the bath brush to ensure that the number of both is equal and that each second bristle area 21 corresponds one-to-one with each fourth bristle area 31. For example, through mold design and bristle planting process, the layout of bristle areas on each board surface is ensured to be symmetrical and the number is matched. This design of equal quantity and one-to-one correspondence ensures that the bath brush provides a similar bristle distribution and temperature-sensitive color-changing effect regardless of whether the first board surface 2 or the second board surface 3 is used. This ensures the balance and consistency of the bath brush when used on both sides, improving the practicality and user experience of the bath brush.

[0047] In some optional embodiments, five second bristle zones 21 and five fourth bristle zones 31 are provided on the base plate 1, and through precise calculation and layout, these five bristle zones are arranged in a pentagonal shape. Mold forming and bristle positioning implantation technology are employed to ensure the accurate position and shape of the bristle zones. The pentagonal shape of the bristle zones allows the bath brush to better conform to the body's curves when in contact with the body, providing a more comprehensive and comfortable cleaning effect, especially for joints or irregular areas. At the same time, this unique shape also enhances the aesthetic appeal of the bath brush.

[0048] In some optional embodiments, in the first bristle area 20, multiple first bristle units 200 are radially distributed with the center of the first plate surface 2 as the origin. A special bristle planting process ensures that the first bristle units 200 are arranged uniformly and orderly. In each second bristle area 21, multiple second bristle units 210 are evenly distributed, using a random or regular arrangement to ensure uniform bristle density within the area. The radially distributed first bristle units 200 can better concentrate their force during bathing, providing more effective cleaning for key areas such as the center of the back. The evenly distributed second bristle units 210 in the second bristle area 21 can evenly clean larger areas of the body, ensuring consistent cleaning results.

[0049] In some optional embodiments, the first bristle unit 200 is made in a pyramidal shape, using plastic or silicone material, and injection molded. The second bristle unit 210 is made in a rounded, raised shape, also using a suitable material and manufactured through a corresponding molding process. These bristle units of different shapes are then implanted into the corresponding bristle areas according to design requirements. The pyramidal-shaped first bristle unit 200, with its pointed tip, can more deeply clean pores and skin texture, effectively removing dirt and dead skin cells. The rounded, raised second bristle unit 210 can produce a gentle massage effect upon contact with the skin, promoting blood circulation while reducing skin irritation, making the bathing process more comfortable.

[0050] In some optional embodiments, during bristle fabrication, the bristle length is controlled so that the distance from the end face of the first bristle unit 200 to the first plate surface 2 is greater than the distance from the end face of the second bristle unit 210 to the first plate surface 2. A precise bristle cutting process ensures the accuracy of the bristle length. The longer first bristle unit 200 can contact the skin more deeply, providing stronger cleaning power and is suitable for cleaning areas with more dirt. The shorter second bristle unit 210 is more suitable for gentle cleaning and massage, avoiding excessive pulling and irritation to the skin, thus meeting the cleaning needs of different areas.

[0051] In some optional embodiments, a hanging ring 4 is integrally formed on one side of the base plate 1 to ensure its sturdiness and durability. The hanging ring 4 allows users to easily hang the bath brush on a hook in the bathroom for convenient storage and drying, keeping the bath brush dry and hygienic and extending its service life. Through the above specific embodiments, this temperature-sensitive color-changing multifunctional bath brush achieves an organic combination of multiple functions, providing users with a more convenient, comfortable, and enjoyable bathing experience.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
