Description

Technical Field

[0001] This utility model patent relates to the field of stereoscopic painting technology, and in particular to a thermochromic painting. Background Technology

[0002] Ousu is a traditional sculptural art form originating in Wenzhou, Zhejiang Province. It evolved from the lacquer-piling technique in traditional Chinese lacquer art and is named after the Oujiang River basin in southern Zhejiang, where it originated. The process involves applying paint or alkyd varnish to a base with a design drawing. While the varnish is semi-dry, colored clay is piled onto the base according to the design, then pressed and smoothed with tools to create the sculpted form. Through a combination of high and low relief, a three-dimensional painting with a colored relief effect and a sense of depth is achieved.

[0003] The colored clay used in Ou clay sculpture is based on mineral pigments such as indigo, malachite, azurite, gamboge, vermilion, ochre, and lithopone, mixed with boiled tung oil. Because tung oil is clear and transparent, the resulting colors are bright and vivid. Combined with refined white clay (after processing), the clay is natural, delicate, has low shrinkage, and is durable. All of these are pure natural materials, so the colors are not easy to fade.

[0004] Thermochromic clay can be easily made by mixing thermochromic powder into colored clay, allowing for different 3D effects such as visibility and color changes through temperature-sensitive zones. However, ordinary thermochromic powder is unstable, resulting in a short color-changing period for thermochromic clay. After 1-2 years, problems such as insensitivity to color change, no color change, or uneven color change can occur, affecting the overall expression of the 3D artwork. Directly covering and repairing thermochromic coatings or clay will destroy the original 3D texture. If repair is done by partially removing and then re-sculpting, the hardening of the clay after drying and the varying depths of engravings in different designs make removal time-consuming, laborious, and difficult to achieve a flat surface suitable for re-sculpting. Therefore, a 3D artwork that allows for easy replacement of the thermochromic zone re-sculpted body is needed. Utility Model Content

[0005] The purpose of this invention is to solve existing technical problems by proposing a temperature-sensitive color-changing painting.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a temperature-sensitive color-changing painting, comprising a detachably connected heat-conducting plate and a heat-insulating base plate.

[0007] The heat insulation base plate has perforated holes, and the top surface of the heat insulation base plate is covered with a first layer of plastic. Several fixing posts for positioning the heat conduction plate are arranged along the edge of the perforated holes on the bottom surface of the heat insulation base plate.

[0008] The heat-conducting plate includes a mounting plate and a fitting block. The fitting block fits into the hollow hole. A second layer of plastic is deposited on the top surface of the fitting block, and the mounting plate is connected to the bottom surface. The mounting plate has several mounting holes that match the insertion of the fixing post. The mounting plate is also connected to a heating element. The heating element is connected to a temperature control switch via a wire. The temperature control switch controls the temperature of the heat-conducting plate.

[0009] The second sculpted body was formed by thermochromic clay.

[0010] Preferably, the number of perforated holes is not less than one, and the perforated holes and the interlocking blocks correspond one-to-one.

[0011] Preferably, the fixing column is glued to the bottom surface of the heat insulation base plate.

[0012] Preferably, the edge of the heat-insulating base plate extends downward to form a support frame, and the height of the support frame is equal to the thickness of the heat-conducting plate.

[0013] Preferably, the heating element is a heating strip arranged around the side of the mounting plate, the support frame has wire holes for threading wires, and the temperature control switch is fixed to the outer surface of the support frame.

[0014] Preferably, the temperature control switch is magnetically attached to the support frame, a magnetic sheet is attached to the inner surface of the support frame, and the temperature control switch has a built-in magnetic block that cooperates with the magnetic sheet.

[0015] The beneficial effects of this utility model are as follows: Through the detachable heat-conducting plate and heat-insulating base plate, the second plastic body can be easily separated from the first plastic body without interfering with the plastic modeling process. The failed second plastic body can be easily reshaped after removal, maintaining the temperature change effect of the 3D painting. The decorative effect of the 3D painting can also be enriched by replacing the second plastic body on different heat-conducting plates. The heat-insulating base plate effectively reduces heat consumption and extends the service life of the heating element. The structure of the heat-conducting plate and heat-insulating base plate is similar to that of commonly used base plates in Ou plastic, making it easy to use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In conjunction with the embodiments and appendices Figure 1-5 A thermochromic painting includes a detachably connected heat-conducting plate 2 and a heat-insulating base plate 11.

[0023] The heat insulation base plate 11 has a perforated hole 110, and the top surface of the heat insulation base plate 11 is molded with a first plastic body 10. The bottom surface of the heat insulation base plate 11 is provided with a number of fixing posts 112 for positioning the heat conduction plate 2 along the edge of the perforated hole 110.

[0024] The heat-conducting plate 2 includes a mounting plate 22 and a fitting block 21. The fitting block 21 fits into the hollow hole 110. A second plastic body 20 is stacked on the top surface of the fitting block 21, and the mounting plate 22 is connected to the bottom surface. The mounting plate 22 has several mounting holes 221 that are matched with the fixing post 112. The mounting plate 22 is also connected to a heating element 3. The heating element 3 is connected to a temperature control switch 5 via a wire 4. The temperature control switch 5 is used to control the temperature of the heat-conducting plate 2.

[0025] The second plastic body 20 is formed by thermochromic clay. There is at least one perforated hole 110 and one heat-conducting plate 2, and the perforated hole 110 and the interlocking block 21 correspond one-to-one. According to the temperature required for the thermochromic powder, the interlocking block and the mounting plate can be set one-to-one or one-to-many to show the thermochromic effect of different temperature zones.

[0026] Furthermore, the temperature-changing range outside the second plastic body is the first range, and the surface of the second plastic body can also be sprayed with temperature-changing ink. The temperature-changing ink displays as the base color at temperatures below the color-changing threshold and as the transparent color at temperatures above or equal to the color-changing threshold. The color-changing threshold is set below the first range, so that the second plastic body can switch between multiple forms, including the base color, the uncolored clay wrapped in the transparent layer, and the color-changing clay wrapped in the transparent layer.

[0027] The shape and position of the perforated hole 110 and the interlocking block 21 can be customized according to the design draft. In use, the first and second sculpted bodies are first shaped on the heat-insulating base plate and the heat-conducting plate, respectively. Then, the heat-conducting plate is inserted and installed from the bottom surface of the heat-insulating base plate. The assembly of the 3D image is completed through the cooperation of the interlocking block and the perforated hole. Alternatively, the heat-conducting plate can be inserted and installed from the bottom surface of the heat-insulating base plate first, so that the top surface of the heat-insulating base plate and the top surface of the heat-conducting plate are on the same horizontal plane, and then the first and second sculpted bodies are shaped. During the shaping process, the temperature can be controlled by a temperature control switch, and the interaction effect between the first sculpted body and the second sculpted body with its temperature-changing effect can be observed for real-time adjustments. When the temperature-changing effect of the second sculpted body decreases, the heat-conducting plate can be removed from the heat-insulating base plate. After repairing or replacing the temperature-changing clay to reshape the second sculpted body, the heat-conducting plate can be reinstalled on the heat-insulating base plate.

[0028] A thermochromic painting, wherein the heat-insulating base plate 11 is a ceramic tile or wooden board, and the fixing post 112 is a plastic post, which is glued to the bottom surface of the heat-insulating base plate. Alternatively, the heat-insulating base plate 11 is a heat-insulating plastic board or acrylic board, and the fixing post 112 and the heat-insulating base plate 11 are integrally molded by injection molding. The heat-conducting plate can be a heat-conducting metal plate or a silicone plate, and the Shore hardness of the heat-insulating base plate and the heat-conducting plate is not less than 75A.

[0029] Furthermore, an elastic ring 113 is fitted around the outer periphery of the fixing column 112. The outer diameter of the elastic ring is interference-fitted with the inner diameter of the mounting hole 22 to achieve a tight connection between the heat-conducting plate and the heat-insulating base plate.

[0030] A thermochromic painting has a heat-insulating base plate 11 with its edge extending downward to form a support frame 11, and the height of the support frame 111 is equal to the thickness of the heat-conducting plate 2.

[0031] A temperature-sensitive color-changing painting, wherein the heating element 3 is a heating strip arranged around the side of the mounting plate, the support frame 111 has a wire hole for threading wires, and the temperature control switch 5 is fixed to the outer surface of the support frame 111.

[0032] Furthermore, the heating strip can be a flexible, thin heating element such as a non-woven fabric heating strip or a silicone electric heating strip.

[0033] A temperature-sensitive color-changing painting, wherein a temperature control switch 5 is magnetically attached to a support frame 111, a magnetic sheet is attached to the inner surface of the support frame 111, and a magnetic block that cooperates with the magnetic sheet is built into the temperature control switch 5.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
