[0038] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figure 1-12 As shown, the utility model provides a children's bowl with cooling and heat preservation functions.

[0040] Example 1

[0041] The bowl body includes a shell 1 and an inner liner 2. The inner liner 2 is located inside the shell 1. The shell 1 and the inner liner 2 are sealed so that a receiving chamber 3 is formed between the shell 1 and the inner liner 2. A heat insulating layer 5 is provided between the shell 1 and the receiving chamber 3. The heat insulating layer 5 is not connected to the receiving chamber 3. At the same time, a phase change heat storage agent 4 is injected into the receiving chamber 3. The melting point of the phase change heat storage agent 4 is between 45°C and 65°C. Phase change heat storage is a technology that utilizes a substance to absorb or release a large amount of heat during a phase change (such as solid-liquid, liquid-gas, etc.). When the phase change heat storage agent 4 changes from one phase to another (such as solid to liquid, or liquid to gas), it absorbs or releases a large amount of latent heat. Therefore, more heat can be stored in a smaller volume. This heat can be extracted or released by controlling the phase change process when needed. The phase change heat storage process can usually be carried out at a constant temperature or in a very small temperature range, which is limited to between 45°C and 65°C in the utility model. For the solid-liquid phase change heat storage agent 4, its volume change during the phase change process is usually small, which helps to reduce the mechanical stress and system complexity caused by the volume change. For example, during the solid-liquid phase change process, the phase change heat storage agent 4 will absorb a large amount of heat when melting, and release this heat when solidifying. When there is hot food in the inner tank 2, the accommodating cavity 3 absorbs heat. If the temperature is lower than the melting point of the phase change heat storage agent 4, the phase change heat storage agent 4 will release heat for heat preservation, so that the cooling and heat preservation effects of the children's bowl with cooling and heat preservation functions are better. When in use, the heat insulation layer 5 can reduce the heat loss of the phase change heat storage agent 4 in the accommodating cavity 3, prevent the stored heat from being lost to the outside all the time, and prevent burns during use.

[0042] The phase change heat storage agent 4 is paraffin, stearic acid, palmitic acid or polyethylene glycol. The inner liner 2 is made of 304 stainless steel.

[0043] To facilitate the grasping of the bowl, a handle 10 is also provided on the shell 1, and the handle 10 can be provided on one side or multiple sides of the shell 1, and the bowl is carried by the handle 10. And by providing a protrusion 1001 on the inner side of the handle 10, the friction force is increased, making the grasping of the bowl more stable.

[0044] like Fig. 9 As shown, in order to facilitate the injection of the phase change heat storage agent 4 into the accommodating chamber 3, an injection hole 101 is opened at the bottom of the shell 1, and the injection hole 101 is connected to the accommodating chamber 3. In order to close the accommodating chamber 3, a hole plug 8 is arranged on the injection hole 101, so that the injection hole 101 does not affect the closed state of the accommodating chamber 3, and can facilitate the injection of the phase change heat storage agent 4.

[0045] like Figure 4As shown, the hole plug 8 includes a column 801 and a cover 802. The column 801 is arranged at the bottom of the cover 802. The column 801 is inserted into the injection hole 101 to block it. The cover 802 is located outside the injection hole 101 for easy opening. An arc-shaped protrusion 8021 is arranged on the cover 802, and the user can take out the hole plug 8 through the arc-shaped protrusion 8021. The injection hole 101 is closed and not connected to the heat insulation layer 5.

[0046] like Figure 5 As shown in Figure 9, in order to prevent the hole plug 8 from affecting the placement balance of the bowl body, a bottom plate 104 and an annular protrusion 103 are provided at the bottom of the shell 1. The annular protrusion 103 is arranged on the outer edge of the bottom plate 104. The height of the bottom plate 104 is raised so that when the hole plug 8 is located in the injection hole 101, it is still located in the annular protrusion 103 and will not protrude from the annular protrusion 103. By not affecting the placement balance of the bowl body, the use of the bowl body is not affected.

[0047] like Figure 3 As shown, the sealing effect between the outer shell 1 and the inner liner 2 is better. A ramp 102 is provided on the top outer edge of the outer shell 1. The ramp 102 is inclined toward the inner liner 2. A slot 201 is provided on the top outer edge of the inner liner 2. The slot 201 is matched with the ramp 102. A sealing ring 9 is provided between the ramp 102 and the slot 201 to achieve a better sealing effect.

[0048] Example 2

[0049] In order to facilitate the processing of the heat insulating layer 5 , the air passage between the inner wall 105 and the outer wall 106 of the outer shell 1 can be set to be hollow, thereby forming the heat insulating layer 5 .

[0050] Example 3

[0051] like Figure 7 As shown, the difference between this embodiment and embodiment 2 is that a heat insulation layer 5 can also be added between the outer shell 1 and the liner 2, and the heat insulation layer 5 is located between the accommodating cavity 3 and the inner wall of the outer shell 1, and the heat insulation layer 5 is not connected to the accommodating cavity 3. The heat insulation layer 5 in this embodiment is a heat insulation material adhered to the inner wall 105 of the outer shell 1.

[0052] The thermal insulation material in Example 2 and Example 3 includes one of rock wool, glass fiber, vacuum insulation panel, and polystyrene foam.

[0053] Example 4

[0054] Based on Example 1, this embodiment is provided with a thermochromic component 6 on the outer side of the shell 1. The thermochromic component 6 includes a temperature sensing part and a temperature sensing material. The temperature sensing part is filled with the temperature sensing material. Both ends of the temperature sensing part are closed. One end is located on the outer side of the shell 1. This end is closed with a transparent material, and the other end is in contact with the phase-change heat storage agent 4. The end of the temperature sensing part in contact with the phase-change heat storage agent 4 is set to a heat-conductive material, so that the temperature sensing material can sense the temperature and change color. By allowing the user to perceive it at one end on the outer side of the shell 1, the user can observe the real-time temperature of the bowl body.

[0055] Thermochromic materials can sense temperatures between 40°C and 70°C. Thermochromic materials can be materials such as thermochromic powder, thermochromic paint, thermochromic ink, and thermochromic water slurry.

[0056] Thermochromic materials mainly change their internal molecules or structures when heated, resulting in changes in the polarization degree of the resonant structure, electrical conductivity or redox reactions of organic molecules, which in turn cause changes in the absorption and reflection spectra, thereby presenting different colors.

[0057] Example 5

[0058] like Figure 10-11 As shown, this embodiment adds a control panel 7 on the basis of Embodiment 1 and Embodiment 2, so as to facilitate the user to observe the temperature.

[0059] In order to facilitate the user to promptly detect temperature changes, a control panel 7 is provided in the insulation layer 5, and the control panel 7 is connected to a temperature sensor 701 and a display panel 702. The temperature sensor 701 determines the temperature of the inner tank 2 by sensing the temperature of the accommodating cavity 3, and then displays the real-time temperature through the display panel 702. The display panel 702 is embedded in the outer shell 1 for the user to observe.

[0060] In order to save power and energy, a power button 703 is provided on one side of the display panel 702 for turning off the display function of the display panel 702 .

[0061] Example 6

[0062] In this embodiment, based on the first embodiment, the outer shell 1 and the inner shell 2 are configured to be detachable.

[0063] In order to increase the service life of the food bowl and its convenience and practicality, the outer shell 1 and the inner liner 2 can also be set to be detachably connected, that is, the inner liner 2 and the outer shell 1 can be separated. The user can separate the inner liner 2 and the outer shell 1 for easy cleaning and self-replacement of the phase change heat storage agent 4 through the injection hole 101.

[0064] How it works

[0065] Taking paraffin as an example, paraffin has high latent heat of phase change and almost no supercooling phenomenon. It has low vapor pressure when melted, is not easy to undergo chemical reactions and has good chemical stability. After multiple absorption and release of heat, the phase change temperature and latent heat of phase change change little, and there is no phase separation or corrosiveness. Specifically, use a baby food bowl injected with paraffin. After pouring 100°C water into it, it quickly melts and absorbs a large amount of heat. Due to heat transfer, the boiling water quickly cools down to about 53°C. When the water continues to cool down below 53°C, the liquid paraffin gradually solidifies and releases the heat originally absorbed, so that the water temperature remains constant at 53°C for a long time.

[0066] Experimental content

[0067] like Fig.12 As shown, line segment 1 is an ordinary water-filled bowl, and line segment 2 is the supplementary food bowl provided by the utility model. By using the supplementary food bowl provided by the utility model and the ordinary water-filled bowl for data comparison, 100°C water is added at the same time, the temperature of the water in the bowl is measured with a thermometer, a set of data is recorded every 2 seconds, entered into a table, and a cooling curve is drawn. It is known from the experimental data that the supplementary food bowl provided by the utility model cools down 10°C faster than the ordinary water-filled bowl.
