[0032] The automatic cooling fan for fish tanks of the utility model monitors the water temperature in the fish tank in real time through a temperature probe. The main control board controls the operation of the fan assembly according to the water temperature monitored by the temperature probe. The fan assembly outputs wind force to promote the air flow on the water surface of the fish tank to reduce the temperature of the fish tank. The technical solution of the utility model uses wind force to promote air flow and water surface evaporation to reduce the water temperature. Compared with the traditional fish tank cooling solution using a compressor refrigerator or a semiconductor refrigerator, the power demand of the utility model is low, thereby greatly saving energy consumption.

[0038] See also Figure 1 In a preferred embodiment, a rotating shaft 9 is provided on both sides of the air guide groove 6 to rotate and adjust the angle of the air guide groove 6 on the housing.

[0039] See also Figure 1 and Figure 5 In a preferred embodiment, a spotlight 10 integrated with the fan assembly is also included to provide lighting into the fish tank.

[0040] See also Figure 1 and Figure 5 In a preferred embodiment, the fan assembly includes a fixed bracket 11 with an adjustable fixed angle, and the fixed bracket 11 is used to fix the fan assembly on the side of the fish tank. The spotlight 10 is installed on the top of the fixed bracket 11 obliquely downward.

[0041] See also Figure 1 In a preferred embodiment, a display 12 is further included, and the display 12 is connected to the main control board 1 to display the temperature and the control interface. When the display 12 is directly mounted on the main control board 1, a window can be opened on the housing to expose the display 12.

[0042] In a preferred embodiment, the automatic cooling fan of the fish tank improves the efficiency and flexibility of cooling and lighting through careful design. The centrifugal fan is located inside the housing, sucks air through the air inlet, and cooperates with the air guide groove on the housing to achieve directional output of wind force, thereby enhancing the cooling effect. The grille vents set on the air guide groove are evenly distributed in the horizontal direction to ensure that the wind force evenly covers the water surface of the fish tank, thereby improving the uniformity and efficiency of cooling. The rotating shaft design on both sides of the air guide groove enables the user to adjust the wind force direction according to the specific needs of the fish tank, thereby further optimizing the cooling performance.

[0043] The fan assembly uses multiple fan units arranged along the length of the air guide slot. This layout not only increases the wind force, but also achieves uniform distribution of wind force, avoids the problem of local uneven wind force, and improves cooling efficiency. The flat fan unit layout design makes the entire system more compact and saves space. In addition, users can also adjust the operating status of each fan unit according to actual needs, which increases the flexibility and adaptability of the system.

[0044] In addition, the fan assembly integrates a spotlight, which realizes the dual functions of cooling and lighting, making the lighting in the fish tank more convenient. The design of the fixed bracket provides free adjustment of the installation angle, so that the fan assembly can be optimized according to the location and structure of the fish tank, improving the flexibility and adaptability of the device. The downward oblique installation of the spotlight ensures effective irradiation of light, providing suitable lighting conditions for fish and aquatic plants, which is conducive to their healthy growth. The spotlight design on the top of the fixed bracket also makes the entire device neater and more compact.

[0045] Specific examples are further exemplified below.

[0046] In this example, the automatic cooling fan system for the fish tank is configured with: a main control panel 1, which integrates a liquid crystal display 12 (for displaying temperature and mode), four control buttons (including switches, lights, modes and temperature settings); two centrifugal impellers as centrifugal fans 3, two 3W outer rotor brushless DC motors 14, an LED spotlight, a temperature probe 2 with waterproof function and a power input interface. The LED spotlight can be independently controlled by the buttons on the main control panel 1. The desired water temperature is set by the button, and the temperature probe will monitor and transmit the water temperature data to the main control panel in real time. When the real-time water temperature exceeds the set value, the main control panel activates the motor, and the motor runs to generate airflow, which changes the wind direction through the volute and the rotatable air guide groove, directly cools the water surface, accelerates air flow and evaporation, and achieves a cooling effect. The air guide groove is designed to be rotatable to meet the needs of fish tanks of different sizes and water levels. The motor and its circuit are treated with moisture-proof treatment, and the motor drive board is glued after being installed on the base to enhance the waterproof performance.

[0047] The power of the product is only 7W, but it can achieve a better cooling effect than a 140W semiconductor refrigerator, significantly saving energy. This example uses an outer rotor brushless motor, which has the advantages of low noise and long life. The system is also integrated into a full-spectrum spotlight, which has the dual functions of cooling and lighting. Only a single power cord is required for connection, using DC5V input. The installation process is simplified. During installation, it can be clamped on the edge of the fish tank or on the tie rod through a fixed bracket. No external water pipe or water pump is required, which simplifies the cooling process. In addition, the cost of this product is much lower than that of traditional compressors or semiconductor refrigerators, only one-tenth of that.

[0048] The specific embodiment also has the following features: real-time temperature display and automatic constant temperature function; LED spotlights are integrated to achieve dual uses in one machine; a modular design is adopted, and the fan, spotlight and fixing seat are equipped with unified sockets, which is convenient for users to choose whether to install the spotlight according to their needs; the fixing bracket is designed to be rotatable 90 degrees to adapt to different installation positions; the air guide slot can also be rotated up to 90 degrees to meet the diverse needs of different users.
