Description

Technical Field

[0001] The utility model relates to the technical field of irons, in particular to an iron with a temperature-changing color block. Background Art

[0002] An iron is a tool used to smooth clothes. In order to improve the non-adhesion of the iron soleplate, a coating is generally provided on the iron soleplate. However, this coating does not have a color-changing function and does not change color with the increase in temperature. During the process of waiting for the iron to cool down after power-off, it is impossible to directly know whether the soleplate has cooled down completely. Especially for some irons without a matching base, this will increase the risk of scalding users.

[0003] In order to solve the above technical problems, a Chinese patent with the publication number CN218711651U discloses a soleplate temperature-changing iron, which includes an iron body with a holding handle. A soleplate is provided at the lower part of the iron body. The soleplate has a thickness and the edge of the soleplate is visible during daily use; a temperature-changing coating is provided outside the soleplate. The soleplate of the above iron is provided with a color-changing temperature-changing coating. After the iron operates, the soleplate will change color to prompt the user. However, the temperature-changing coating contacts and rubs against the clothes, greatly shortening the service life of the color-changing coating.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an iron with a temperature-changing color block aiming at the defects and deficiencies of the prior art. The bottom surface of the temperature-changing color block is higher than the bottom surface of the soleplate. When ironing clothes, the soleplate mainly contacts the clothes, thereby reducing the chance of contact and friction between the temperature-changing color block and the clothes, which is beneficial to improving the service life of the temperature-changing color block.

[0006] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0007] The utility model provides an iron with a temperature-changing color block, which includes a soleplate. Through holes are provided on the soleplate, and temperature-changing color blocks are arranged in the through holes. The bottom surface of the temperature-changing color block is higher than the bottom surface of the soleplate.

[0008] Through the above structural arrangement, the bottom surface of the temperature-changing color block and the bottom surface of the soleplate are not on the same plane. When ironing clothes, the soleplate mainly contacts the clothes, thereby reducing the chance of contact and friction between the temperature-changing color block and the clothes, which is beneficial to improving the service life of the temperature-changing color block.

[0009] It can be understood that the user judges whether the soleplate is cooled by observing the color on the temperature-changing color block.

[0010] According to the above scheme, it also includes a heating element component, and the bottom plate is fixed on the heating element component; the bottom plate and the thermochromic color block are respectively in contact with the heating element component.

[0011] Through the above-mentioned structural arrangement, the heat of the heating element assembly is transferred to the bottom plate and the thermochromic color block.

[0012] According to the above scheme, a groove is provided on the bottom surface of the heating element assembly, and the thermochromic color block is located below the groove; an edge portion is provided on the outer periphery of the thermochromic color block, and the edge portion is provided on the lower opening of the groove and is clamped between the heating element assembly and the bottom plate.

[0013] Existing thermochromic materials will become ineffective when the temperature exceeds 200°C, but the temperature of the soleplate at the highest level when the iron is in use can generally reach 210°C. During long-term use, the temperature is too high, which will easily cause the color-changing characteristics of the thermochromic color block to be lost. Through the above-mentioned structural setting, the groove is located between the heating element and the thermochromic color block, reducing the contact area between the heating element component and the thermochromic color block, and the air in the groove can play a heat-insulating role, which not only prevents the temperature of the thermochromic color block from being too high, but also meets the color-changing requirements.

[0014] According to the above solution, the heating element assembly is detachably fixedly connected to the base plate.

[0015] By providing a detachable fixed connection between the heating element assembly and the bottom plate, the edge of the thermochromic color block can be conveniently clamped between the heating element assembly and the bottom plate, thereby quickly completing the installation of the thermochromic color block.

[0016] According to the above solution, the thermochromic color block includes a substrate and a first thermochromic coating, and the first thermochromic coating is arranged on the bottom surface of the substrate.

[0017] Through the above-mentioned structural setting, the color of the first thermochromic coating will change when the preset temperature is reached; the user can judge whether the bottom plate is cooled by observing the color of the first thermochromic coating.

[0018] According to the above scheme, the first thermochromic coating is gray at room temperature and turns red after reaching the temperature change temperature. It is understandable that the color of the first thermochromic coating at room temperature and the temperature change temperature can be set according to actual needs. The utility model sets the first thermochromic coating to be gray at room temperature and turn red after reaching the temperature change temperature, so that the first thermochromic coating forms a clear contrast with the color of the bottom plate after the color change, making it easier for users to perceive the risk of scalding.

[0019] According to the above solution, the temperature-changing color patch further includes a transparent protective coating, and the transparent protective coating is disposed on the first temperature-changing coating. By providing the transparent protective coating, the first temperature-changing coating can be protected from being worn, which is beneficial to extending the service life of the first temperature-changing coating.

[0020] According to the above solution, the temperature-changing color patch includes a substrate, a red primer layer, and a second temperature-changing coating. The red primer layer is disposed on the bottom surface of the substrate, and the second temperature-changing coating is disposed on the red primer layer; the second temperature-changing coating is gray at normal temperature and becomes transparent when the temperature reaches the temperature-changing temperature.

[0021] Through the above structural arrangement, when the second temperature-changing coating becomes transparent when the temperature reaches the temperature-changing temperature, the user can see the color of the red primer layer; when the second temperature-changing coating is below the temperature-changing temperature, the color of the second temperature-changing coating blocks the color of the red primer layer.

[0022] It can be understood that the color of the red primer layer does not change with temperature.

[0023] According to the above solution, the temperature-changing color patch further includes a transparent protective coating, and the transparent protective coating is disposed on the second temperature-changing coating.

[0024] By providing the transparent protective coating, the second temperature-changing coating can be protected from being worn, which is beneficial to extending the service life of the second temperature-changing coating.

[0025] It can be understood that the temperature-changing temperatures of the first temperature-changing coating and the second temperature-changing coating can be set according to actual needs.

[0026] According to the above solution, an anti-scalding mark is provided on the bottom surface of the temperature-changing color patch. By providing the anti-scalding mark, a warning function can be achieved.

[0027] The beneficial effects of the present utility model are as follows:

[0028] A through hole is provided on the bottom plate of the present utility model, and a temperature-changing color patch is provided in the through hole. The bottom surface of the temperature-changing color patch is higher than the bottom surface of the bottom plate; such that the bottom surface of the temperature-changing color patch and the bottom surface of the bottom plate are not in the same plane. When ironing clothes, mainly the bottom plate contacts the clothes, thereby reducing the chance of contact and friction between the temperature-changing color patch and the clothes, which is beneficial to improving the service life of the temperature-changing color patch.

[0038] Through the above - mentioned structural arrangement, the bottom surface of the temperature - changing color patch 2 and the bottom surface of the bottom plate 1 are not in the same plane. When ironing clothes, mainly the bottom plate 1 contacts the clothes, thereby reducing the chance of contact and friction between the temperature - changing color patch 2 and the clothes, which is beneficial to improving the service life of the temperature - changing color patch 2.

[0042] Furthermore, the heating element assembly 3 is detachably and fixedly connected to the bottom plate 1. By setting the heating element assembly 3 to be detachably and fixedly connected to the bottom plate 1, the edge portion 21 of the temperature-changing color patch 2 can be conveniently clamped between the heating element assembly 3 and the bottom plate 1, thus quickly completing the installation of the temperature-changing color patch 2.

[0043] Furthermore, an anti-scalding mark 4 is provided on the bottom surface of the temperature-changing color patch 2. By setting the anti-scalding mark 4, a warning effect can be achieved.
