Description

Technical Field:

[0001] The utility model belongs to the technical field of daily necessities, and particularly refers to a temperature-sensitive color-changing basin. Background Art:

[0002] Traditional washbasins and bathtubs do not have the effect of temperature-sensitive color change. Regardless of whether they are filled with hot water or cold water, their colors are fixed. Even if there are patterns on some children's bathtubs and washbasins, it is still limited in improving the initiative and enthusiasm of children to wash their faces and take baths. In addition, the existing patterns are formed by printing patterns on a film. During the molding process of the film and the basin body, it is easy to shift, resulting in a reduction in the product qualification rate. Summary of the Invention:

[0003] The purpose of the utility model is to provide a temperature-sensitive color-changing basin that improves the fun through temperature-sensitive color change and has a high product qualification rate.

[0004] The utility model is realized as follows:

[0005] A temperature-sensitive color-changing basin includes a basin body, and a film is embedded in the inner bottom surface of the basin body. The upper surface of the film is exposed, and a temperature-sensitive color-changing layer is provided on the upper surface of the film. Limiting grooves for limiting the film during in-mold sticking injection are provided on both sides of the film.

[0006] In the above-mentioned temperature-sensitive color-changing basin, the thickness of the film is 0.03 - 0.12 mm.

[0007] In the above-mentioned temperature-sensitive color-changing basin, the thickness of the temperature-sensitive color-changing layer is 0.35 - 0.37 mm.

[0008] In the above-mentioned temperature-sensitive color-changing basin, the basin body is a washbasin body or a bathtub body.

[0009] In the above-mentioned temperature-sensitive color-changing basin, the film is a matte OPP film or a PET film.

[0010] In the above-mentioned temperature-sensitive color-changing basin, the film is circular or elliptical or polygonal.

[0011] The utility model has the following prominent advantages compared with the prior art:

[0012] 1. The utility model realizes the color change of the temperature-sensitive color-changing layer with the change of the water temperature by arranging a film with a temperature-sensitive color-changing layer on the bottom surface of the basin body, which is convenient for observing the water temperature in the basin, greatly improves the fun of using the product, and improves the initiative and enthusiasm of children to wash their faces and take baths.

[0013] 2. The two ends of the film of the utility model are provided with limiting grooves, which can position the film, ensure the fixed position between the pattern of the temperature-sensitive color-changing layer and the basin body, and improve the product qualification rate. Brief Description of the Drawings:

[0014] Figure 1 is a three-dimensional schematic diagram of the present utility model;

[0015] Figure 2 is a schematic diagram of the temperature-sensitive color-changing layer of the present utility model provided on the film;

[0016] Figure 3 is a simplified cross-sectional schematic diagram of the film and the temperature-sensitive color-changing layer provided on the basin body of the present utility model. The thickness ratios of the basin body, the film, and the temperature-sensitive color-changing layer in the figure are not in accordance with the actual situation. The purpose is to show the positional relationship between the layers.

[0017] In the figure: 1, basin body; 2, film; 3, circuit board; 4, limiting groove. Detailed Description of the Invention:

[0018] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —3:

[0019] The present utility model provides a temperature-sensitive color-changing basin, which includes a basin body 1. A film 2 is embedded in the inner bottom surface of the basin body 1. The upper surface of the film 2 is exposed, and a temperature-sensitive color-changing layer 3 is provided on the upper surface of the film 2. Limiting grooves 4 for limiting the film 2 during in-mold sticking injection are provided on both sides of the film 2.

[0020] As can be seen from the above, the film 2 of the present utility model is embedded in the basin body 1, and the two are firmly connected.

[0021] Furthermore, the film 2 is a matte OPP film or a PET film. Among them, matte OPP is a special polypropylene film. An anti-glare agent is added during the production process, which reduces the gloss of the film, increases the haze, and can eliminate the reflection on the film surface. The PET film is also known as a high-temperature resistant polyester film. In addition, it also has good tensile strength, impact strength, rigidity, toughness, and transparency, etc. The PET film has excellent mechanical properties. Its toughness is the best among all thermoplastics. Its tensile strength and impact strength are much higher than those of general films; and it has good stiffness, stable dimensions, and is suitable for secondary processing such as printing and paper bags.

[0022] In addition, the thickness of the film 2 of the present utility model is 0.03 - 0.12 mm. The thickness of the temperature-sensitive color-changing layer 3 is 0.35 - 0.37 mm.

[0023] The thickness of the film 2 and the thickness of the temperature-sensitive color-changing layer 3 can take any value within the above range.

[0024] It should be noted that the temperature-sensitive color-changing layer 3 can be made of temperature-sensitive color-changing materials that can be purchased on the market.

[0025] As can be seen from the above, the present utility model includes a basin body 1. Specifically, the basin body 1 is a washbasin body or a bathtub body. Therefore, a temperature-sensitive color-changing washbasin and a temperature-sensitive color-changing bathtub can be formed.

[0026] The shape of the thin film 2 of the present utility model can be set according to the actual situation. In this embodiment, the thin film 2 is circular, and it can also be other shapes such as oval or polygon. In specific applications, shapes such as cartoon images, vegetables, fruits, etc. can also be adopted.

[0027] The temperature-sensitive color-changing layer 3 of the present utility model displays different colors according to the temperature of the liquid in the basin body 1, which can increase aesthetic feeling and childlike interest, improve the initiative and enthusiasm of children to wash their faces or take baths, and facilitate children to develop good hygiene habits.

[0028] The production method of the present utility model is as follows:

[0029] 1. Set the temperature-sensitive color-changing layer 3 on the thin film 2 by means of ink printing or the like;

[0030] 2. Install the thin film 2 with the temperature-sensitive color-changing layer 3 into a mold, and limit the position through the limiting groove 4 on the thin film 2;

[0031] 3. Inject plastic into the mold. Finally, the thin film 2 is formed on the inner bottom surface of the basin body, and the upper surface of the thin film 2 and the temperature-sensitive color-changing layer 3 are exposed.

[0032] The above embodiments are only one of the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, all equivalent changes made according to the shape, structure, and principle of the present utility model should be covered within the protection scope of the present utility model.
