[0002] Rodent-proof refrigeration fan covers are designed to protect refrigeration equipment from pests such as rats when operating in low-temperature environments. Rats and other pests not only cause physical damage to equipment but can also contaminate food, affecting food safety and hygiene. Therefore, it is crucial to employ protective designs to prevent rats from gnawing on the wiring, pipes, and other components of refrigeration equipment.

[0003] While existing technologies utilize freezer hoods during refrigerator operation, rodent damage to these hoods can lead to food contamination, compromising food safety and hygiene. Therefore, those skilled in the art have developed a rodent-proof freezer hood to address the problems mentioned in the background section. Utility Model Content

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2 and 3 As shown, a protective freezer hood with rodent-proof function includes a mounting plate 4. The front end of the mounting plate 4 has four mounting holes 3 arranged in a rectangular array. A fixing device 1 is provided at the front end of the mounting plate 4. A ventilation device 2 is provided on the inner wall of the fixing device 1. A first protective cover 5 is fixedly connected to the front end of the mounting bracket 101. A second protective cover 6 is fixedly connected to the inner wall of the first protective cover 5. The first protective cover 5 is a flared outward trumpet-shaped structure, and the second protective cover 6 is a flared inward trumpet-shaped mechanism. The inner wall of the first protective cover 5 and the side walls of the second protective cover 6 can prevent rodents from climbing. A filter screen 7 is fixedly connected to the front end of the second protective cover 6. The entire device is connected to the refrigerator air vent through the mounting holes 3 on the mounting plate 4. When a rodent appears, since the side walls of the first protective cover 5 and the second protective cover 6 are both in an inclined state, it can effectively prevent the rodent from climbing to the filter screen 7 and entering the equipment, effectively achieving the purpose of preventing rodents from gnawing on the internal circuitry.

[0024] like Figure 3 , Figure 5As shown, a mounting bracket 101 is fixedly connected to the front end of the mounting plate 4, and a rail 102 is fixedly connected to the top of the mounting bracket 101. A collection box 103 is slidably arranged on the inner wall of the rail 102. A water inlet 104 communicating with the inside of the collection box 103 is opened at the bottom of the inner wall of the mounting bracket 101. Two-way screw rods 106 are rotatably connected to both sides of the inner wall of the mounting bracket 101. Locking blocks 105 are threadedly connected to both sides of the side wall of the two-way screw rods 106. A knob 107 is fixedly connected to the top of the two-way screw rods 106. The slot 203 on the ventilation device 2 is placed into the locking block 105. By rotating the knob 107, the locking block 105 can be moved by the two-way screw rods 106. The locking block 105 can be used to fix the ventilation device 2, effectively improving the overall stability of the device. It can realize the maintenance and replacement of the ventilation device 2. At the same time, the collection box 103 in the rail 102 can collect the water generated by the device and prevent it from overflowing.

[0025] like Figure 3 , Figure 4 As shown, the inner wall of the mounting bracket 101 is provided with a mounting block 202. When the locking block 105 enters the inside of the locking groove 203, the locking block 105 can be inserted into the inner wall of the locking groove 203 by rotating the knob 107, effectively installing the mounting block 202. Two locking grooves 203 are respectively opened on both sides of the mounting block 202 to cooperate with the locking block 105. A fixing frame 201 is fixedly connected to the middle of the mounting block 202. A ventilation fan blade 206 is rotatably connected to the middle of the front end of the inner wall of the fixing frame 201. A drain outlet 207 communicating with the inner wall of the water inlet 104 is opened at the bottom of the inner wall of the mounting block 202. The fixing frame 202... An electric heating plate 204 is fixedly connected to the rear end of the inner wall. A controller 205, which is electrically connected to the electric heating plate 204, is fixedly connected to one side of the rear end of the mounting block 202. A ventilation fan blade 206 is installed in the fixing frame 201 for auxiliary ventilation. During long-term use, frost will form on the surface of the ventilation fan blade 206. At this time, the electric heating plate 204 can be turned on to heat the surface of the ventilation fan blade 206 for a period of time, so that the frost on the surface of the ventilation fan blade 206 can be melted. The melted water is collected through the drain outlet 207 and collected through the collection box 103, which effectively improves the overall performance of the device.

[0026] It should be noted that this type of rodent-proof protective freezer vent cover is connected to the refrigerator air vent via the mounting holes 3 on the mounting plate 4 during use. When a mouse appears, the inclined side walls of the first and second protective covers 5 and 6 effectively prevent the mouse from climbing onto the filter 7 and entering the equipment. The slot 203 on the ventilation device 2 is placed into the locking block 105. Rotating the knob 107 moves the locking block 105 using the bidirectional screw 106, thus securing the ventilation device 2. Improving the overall stability of the device allows for the maintenance and replacement of the ventilation device 2. Simultaneously, the collection box 103 in the rail 102 can collect the water generated by the device. A ventilation fan blade 206 is installed in the mounting bracket 201 to assist ventilation. During prolonged use, frost will form on the surface of the ventilation fan blade 206. At this time, turning on the heating plate 204 can heat the surface of the ventilation fan blade 206 for a period of time, allowing the frost on the surface of the ventilation fan blade 206 to melt. The melted water is then collected through the drain outlet 207 and collected in the collection box 103.

[0027] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
