Detailed implementation method:
[0026] like Figures 1-12 As shown, this specific embodiment adopts the following technical solution: It includes a cartoon shell 1 and a wind power source 2. The interior of the cartoon shell 1 adopts a hollow structure design, and a connecting cavity 101 is provided inside the cartoon shell 1. The wind power source 2 is installed inside the connecting cavity 101. The shell of the wind power source 2 is tightly fitted to the connecting cavity 101 and positioned by the air inlet on the bottom edge of the cartoon shell 1. An air outlet 102 is provided on the top of the cartoon shell 1. The air outlet 102 is used to blow out the air generated by the wind power source 2 to cool down the food. An air inlet 103 is provided at the bottom of the cartoon shell 1. A hanging arm 104 is provided on the cartoon shell 1. The hanging arm 104 is mainly used to hang the machine on the edge of the bowl, cup and other utensils that need to be cooled to achieve fixed air blowing and cooling. A button 105 is provided at the lower rear of the cartoon shell 1.
[0027] The wind power unit 2 consists of a first outer casing 201, a second outer casing 202, a positioning connecting piece 203, a fan 204, a battery 205, and a control panel 206. The first outer casing 201 and the second outer casing 202 are snapped together and fixed. The positioning connecting piece 203 is installed inside the second outer casing 202. An air guide plate 2031 is integrally installed above the positioning connecting piece 203. The positioning connecting piece 203 has a fan positioning seat 2032 and an air inlet 2033. The fan 204 is installed on the fan positioning seat 2032. The battery 205 is located on one side of the upper part of the positioning connecting piece 203, providing power to the entire unit. Below the battery 205 is a control panel 206, which has a fan speed adjustment button 2061 and a charging interface 2062. The fan speed adjustment button 2061 can adjust the fan speed to meet the cooling needs of different foods (e.g., a strong fan speed can be used for hot food that has just come out of the pot, and a weak fan speed can be used for warm food). The control panel 206 is responsible for circuit control, fan speed adjustment and other functions, and works together to ensure the stable operation of the main unit and achieve effective cooling of food. Both the fan 204 and the control panel 206 are connected to the battery 205 through a power cord and are powered by the battery 205.
[0028] The cartoon shell 1 is made of food-grade plastic material. The air inlet 103 of the cartoon shell 1 is equipped with a dustproof net to prevent external dust and other impurities from entering the machine and affecting the normal operation and service life of components such as the fan.
[0029] The lower center of the outer casing 201 has a positioning hole 2011. The upper and lower sides of the outer casing 201 have positioning holes 2012. The upper and lower sides of the outer casing 202 have positioning hooks 2021, which are respectively engaged and fixed with the positioning holes 2012 on the upper and lower sides of the outer casing 201. The upper end of the outer casing 202 has an air outlet 2022, and the bottom end of the outer casing 202 has a heat dissipation air inlet 2023.
[0030] The air guide plate 2031 adopts an arc-shaped structure design. The air guide plate 2031 is set between the air outlet of the fan 204 and the air outlet 102 of the cartoon shell 1. The arc-shaped design optimizes the airflow direction and accurately guides the airflow generated by the fan 204 to the air outlet, greatly improving the concentration and stability of the airflow and making the airflow more focused on cooling the food.
[0031] The fan 204 uses a small DC brushless fan to generate stable airflow. An air inlet screen 2041 is provided on one side of the fan 204 to ensure smooth airflow and filter impurities to protect the fan. The air inlet of the fan 204 corresponds to the air inlet of the wind power source host 1 at the bottom of the cartoon shell 1.
[0032] Battery 205 uses a rechargeable lithium battery with a capacity of 1000mAh. It can be charged by connecting to an external power source through the charging interface (Type-C interface), providing strong battery life. The charging interface is also compatible with common charging devices (such as mobile phone chargers, power banks, etc.) for convenient charging.
[0033] The working principle of this specific embodiment is as follows: When in use, the machine is hung on the edge of a container such as a cup or bowl using the hanging arm 104. Then, the button 105 at the bottom rear of the cartoon shell 1 is pressed, and the fan 204 is powered by the battery 205. The fan 204 draws in air from the air inlet 103, guides it through the air guide plate 2031, and blows it out from the air outlet 102 to cool the food. The fan speed can be adjusted using the fan speed adjustment button 2061 to adapt to different food cooling needs. When charging, the charging cable is inserted into the charging interface 2062 to charge the battery 205.
[0034] This specific implementation features a reasonable structural design, simple operation, and convenient use. The cartoon-shaped outer shell not only enhances the product's fun and aesthetics, but also houses a fixed fan power source. The fan power source does not need to be replaced; consumers only need to purchase shells of different shapes and cartoon designs to meet their diverse needs. The fan power source, combined with the air guide structure, generates concentrated and stable airflow for targeted cooling of food, improving cooling efficiency and solving the problem of scattered airflow from ordinary fans. Details such as the dust filter, rechargeable lithium battery, and fan speed adjustment button further enhance the product's practicality, convenience, and lifespan, making this food cooling hair dryer highly valuable for everyday use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
