Abstract
Description
Technical Field
[0001] This utility model relates to the field of painting tools technology, and in particular to a painting palette that heats evenly. Background Technology
[0002] Painting is an art form that uses manual methods to imitate nature or non-nature on a flat surface to achieve a two-dimensional (planar or three-dimensional) effect. In art education, the paint palette is an indispensable tool in artistic creation. However, in cold weather, especially in northern my country where outdoor temperatures often range from -10 to -20°C, or even colder areas, the paint in the palette may freeze when art teachers lead students to paint beautiful snow scenes outdoors, making it inconvenient for students to paint. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a painting palette that heats evenly.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A uniformly heated painting palette includes a palette body. The upper surface of the palette body has a downwardly recessed inverted conical groove for holding paint. The groove wall is made of a thermally conductive material. The palette body has multiple electric heating rings inside. The multiple electric heating rings are arranged sequentially and spaced apart along the height direction of the inverted conical groove, and the heating power of the multiple electric heating rings decreases from the bottom surface to the top surface of the inverted conical groove. The inner ring of each electric heating ring is in contact with the groove wall of the inverted conical groove.
[0006] Furthermore, there are three electric heating rings, which are designated as the first electric heating ring, the second electric heating ring, and the third electric heating ring from the bottom to the top of the inverted conical groove. The first electric heating ring, the second electric heating ring, and the third electric heating ring are made of the same material, and the cross-sections of the first electric heating ring, the second electric heating ring, and the third electric heating ring are all circular, with the cross-sectional diameters decreasing sequentially.
[0007] Furthermore, the distance between the first and second electric heating rings is equal to the distance between the second and third electric heating rings and is 5mm. The cross-sectional diameters of the first, second, and third electric heating rings are 1mm, 0.8mm, and 0.6mm, respectively.
[0008] Furthermore, there are three electric heating rings, which are designated as the first electric heating ring, the second electric heating ring, and the third electric heating ring from the bottom to the top of the inverted conical groove. The cross-sectional diameters of the first electric heating ring, the second electric heating ring, and the third electric heating ring are all equal, and the materials of the first electric heating ring, the second electric heating ring, and the third electric heating ring are all different, with their corresponding heating coefficients decreasing sequentially.
[0009] Furthermore, the cross-sectional diameters of the first, second, and third electric heating rings are all 0.8 mm.
[0010] Furthermore, there are three electric heating rings, which are designated as the first, second, and third electric heating rings from the bottom to the top of the inverted conical groove. The first, second, and third electric heating rings are made of the same material, and each of them is sheet-shaped with a decreasing cross-sectional width from the bottom to the top of the inverted conical groove.
[0011] Furthermore, the cross-sectional widths of the first, second, and third electric heating rings from the bottom to the top of the inverted conical groove are 1.5 mm, 1 mm, and 0.5 mm, respectively.
[0012] Furthermore, the disc body is equipped with a controller inside, and a temperature sensor is also provided on the upper surface of the disc body. The temperature sensor and multiple electric heating rings are electrically connected to the controller.
[0013] Furthermore, the number of temperature sensors is two or more, and the two or more temperature sensors are evenly distributed around the perimeter of the disk, and each of the two or more temperature sensors is electrically connected to the controller.
[0014] Furthermore, the thickness of the groove wall of the inverted conical groove ranges from 1mm to 3mm, and the thermally conductive material is copper.
[0015] The beneficial effects of this utility model are:
[0016] This utility model provides a uniformly heated painting palette, which has an inverted conical groove formed by a downward indentation on the upper surface of the palette for loading paint. The groove wall is made of a thermally conductive material. The palette has multiple electric heating rings inside, which are arranged at intervals along the height of the inverted conical groove. The heating power of the multiple electric heating rings decreases from the bottom to the top of the inverted conical groove. The inner ring of each electric heating ring is in contact with the groove wall of the inverted conical groove. The design employs an inverted conical groove to concentrate the pigment, which is less prone to freezing compared to spreading the pigment flat, and facilitates pigment application. Furthermore, based on the unique shape of the inverted conical groove, multiple electric heating rings are configured. These rings are spaced apart sequentially along the height of the groove, with their heating power decreasing from the bottom to the top of the groove. This accommodates the varying radii of different horizontal sections of the groove, achieving uniform heating. Additionally, the groove wall is made of a thermally conductive material, and the inner ring of each electric heating ring is in close contact with the groove wall, further ensuring effective heat conduction.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0027] like Figures 1-7 As shown, this utility model provides a uniformly heated painting palette, comprising a palette body 1. The upper surface of the palette body 1 has five inverted conical grooves 11 for loading paint, with a distance of not less than 2 cm between adjacent inverted conical grooves 11. The groove walls of the inverted conical grooves 11 are made of a thermally conductive material, and the thickness of the groove walls ranges from 1 mm to 3 mm, preferably 2 mm. The thermally conductive material is copper.
[0028] The disc body 1 is provided with a plurality of electric heating rings 12. The plurality of electric heating rings 12 are arranged sequentially at intervals along the height direction of the inverted conical groove, and the heating power of the plurality of electric heating rings decreases from the bottom surface to the top surface of the inverted conical groove. The inner ring of each electric heating ring 12 is in contact with the groove wall of the inverted conical groove.
[0029] In this embodiment, the electric heating ring is implemented in the following three specific ways, as follows:
[0030] The first method involves three electric heating rings 12, designated as a first electric heating ring 121, a second electric heating ring 122, and a third electric heating ring 123 from the bottom to the top of the inverted conical groove (i.e., from the upper to the lower surface of the disc). The first, second, and third electric heating rings 121, 122, and 123 are made of the same material, and all have circular cross-sections with decreasing diameters. The distance between the first and second heating rings 121 and 122, and the distance between the second and third heating rings 122 and 123, is equal to 5 mm. The cross-sectional diameters of the first, second, and third heating rings 121, 122, and 123 are 1 mm, 0.8 mm, and 0.6 mm, respectively.
[0031] The first method described above consists of a first electric heating ring, a second electric heating ring, and a third electric heating ring, all made of the same material but with different wire diameters. By setting the specific parameters mentioned above, uniform heating can be achieved.
[0032] The second method involves three electric heating rings 12, designated as a first electric heating ring 121, a second electric heating ring 122, and a third electric heating ring 123 from the bottom to the apex of the inverted conical groove. The cross-sectional diameters of the first, second, and third electric heating rings 121, 122, and 123 are all equal, but their materials are different, with their corresponding heating coefficients decreasing sequentially. The cross-sectional diameter of each of the first, second, and third electric heating rings 121 and 122 is 0.8 mm.
[0033] The second method described above also consists of a first heating ring, a second heating ring, and a third heating ring. However, it differs from the first method in that it uses different materials but the same wire diameter. By setting the specific parameters mentioned above, uniform heating can be achieved. It should be noted that the heating coefficient is determined by the material.
[0034] The third method involves three electric heating rings 12, designated as a first electric heating ring 121, a second electric heating ring 122, and a third electric heating ring 123 from the bottom to the top of the inverted conical groove. These rings are made of the same material, are sheet-like, and their cross-sectional widths decrease sequentially from the bottom to the top of the inverted conical groove. The cross-sectional widths of the first electric heating ring 121, the second electric heating ring 122, and the third electric heating ring 123 from the bottom to the top of the inverted conical groove are 1.5 mm, 1 mm, and 0.5 mm, respectively.
[0035] The third method described above also consists of a first electric heating ring, a second electric heating ring, and a third electric heating ring. However, the main difference between this method and the first and second methods is that the electric heating ring is sheet-like, meaning that the electric heating ring can achieve surface-to-surface contact with the sidewall of the inverted conical groove, thereby improving heat transfer efficiency.
[0036] The upper surface of the disc 1 is also provided with a strip-shaped groove 13 for placing a drawing pen, and the strip-shaped groove 13 is located on one side of the inverted conical groove 11. The depth, width and length of the strip-shaped groove 13 are adapted to the drawing pen. The bottom of the strip-shaped groove 13 is also provided with anti-slip texture (not shown in the figure), and the anti-slip texture is arranged along the length direction of the strip-shaped groove.
[0037] The disk body 1 is also equipped with a controller 14 inside, and the upper surface of the disk body 1 is also equipped with two or more temperature sensors (not shown in the figure). The two or more temperature sensors are evenly distributed around the disk body, and each of the two or more temperature sensors is electrically connected to the controller 14. The controller and temperature sensors can both use existing electronic devices.
[0038] The aforementioned uniformly heated painting palette also includes a flip-top housing 2. The palette body can be detachably placed inside the housing, and can be removed from the housing 2 for use. After use, it should be cleaned, and then the palette body 1 should be placed back into the housing 2 and the cover 21 should be closed to seal it and protect the palette body.
[0039] In summary, the present invention provides a uniformly heated painting palette, which has a concave groove on the upper surface of the palette body to hold pigments. The groove wall is made of a heat-conducting material. The palette body has multiple electric heating rings inside, which are arranged at intervals along the height direction of the concave groove. The heating power of the multiple electric heating rings decreases from the bottom to the top of the concave groove. The inner ring of each electric heating ring is in contact with the groove wall of the concave groove. The design employs an inverted conical groove to concentrate the pigment, which is less prone to freezing compared to spreading the pigment flat, and facilitates pigment application. Furthermore, based on the unique shape of the inverted conical groove, multiple electric heating rings are configured. These rings are spaced apart sequentially along the height of the groove, with their heating power decreasing from the bottom to the top of the groove. This accommodates the varying radii of different horizontal sections of the groove, achieving uniform heating. Additionally, the groove wall is made of a thermally conductive material, and the inner ring of each electric heating ring is in close contact with the groove wall, further ensuring effective heat conduction.

However, the above embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. On the contrary, modifications and equivalent provisions included in the spirit and scope of the claims are all included within the scope of this utility model.
